The following cryptocoins match your criteria (sorted by popularity):
1. Bitcoin (BTC) (1)
Bitcoin (BTC) is a consensus network that enables a new payment system and a completely digital money. It is the first decentralized peer-to-peer payment network that is powered by its users with no central authority or middlemen. From a user perspective, Bitcoin is like cash for the Internet. Bitcoin is the first implementation of a concept called "crypto-currency", suggesting the idea of a new form of money that uses cryptography to control its creation and transactions, rather than a central authority. The first Bitcoin specification and proof of concept was published in 2009 in a cryptography mailing list by Satoshi Nakamoto. Satoshi left the project in late 2010 without revealing much about himself. The community has since grown exponentially with many developers working on Bitcoin. Initial announcement.
2. Zcoin (XZC) (2)
Zcoin (XZC) is a decentralised, open-source cryptocurrency launched in September 2016 as a fork of Bitcoin. With a strong focus on privacy and anonymity of transactions, Zcoin uses the Zerocoin protocol and a concept called "zero-knowledge cryptographic proof" which obfuscates both the sender's and the recipient's transaction data. In effect, the protocol is capable of proving the ownership of a coin without having to reveal which exact coin one owns. Being a proof-of-work cryptocurrency, Zcoin follows the same mining scheme and halving cycle as Bitcoin, eventually generating 21 million coins; however, it uses a different hashing algorithm (Lyra2). 10% of the total Zcoin supply will be distributed to the founders reward fund. Original announcement.
3. Stellar Lumen (XLM) (3)
Stellar Lumen (XLM) is a cryptocurrency used by the Stellar payment network. Launched in July 2014 by Jed Mccaleb, the founder of the failed Mt. Gox Bitcoin exchange and the Ripple payment network, Stellar was originally based on the Ripple consensus protocol, but it was later replaced by the project's rewritten version. It is a proof-of-stake (PoS) coin with a total supply of 100 billion of stellars and an annual inflation of 1%. Unlike most other cryptocurrency projects, Stellar does not provide a desktop client and all transactions are performed through its web wallet. Furthermore, a new account can only be created by an existing Stellar user who has to send a minimum of 20 XLM to the new account; a Facebook account is mandatory to confirm the reception of funds. Original announcement.
4. PIVX (PIVX) (4)
PIVX (PIVX) [formerly DarkNet (DNET)] is a decentralised, open-source cryptocurrency launched in January 2016 as a fork of Dash. As its name original name suggested, DarkNet's focus is on privacy and anonymity of transactions as it is designed to run on anonymous networks (Tor or I2P). The coin started its life as a mineable proof-of-work currency (using the ASIC-resistant Quark algorithm) to generate some 43 million coins, but it became a pure proof-of-stake coin once the initial mining phase was completed (at block 259,200 or about 180 days since the genesis block). About 60,000 coins were pre-mined, but these were destroyed at the completion of the proof-of-work stage. The project re-branded to PIVX in February 2017. Original announcement.
5. Reddcoin (RDD) (5)
Reddcoin (RDD) is a decentralised open-source cryptocurrency forked from Litecoin in early 2014, but it was re-based on Bitcoin in August 2016. It is dedicated to tipping on social networks as a way of bringing cryptocurrency awareness and experience to the general public. Original announcement.
6. NEM (XEM) (6)
NEM (XEM), which stands for New Economy Movement, is a decentralised cryptocurrency launched in March 2015. Inspired by the Nxt project, it was written from scratch in Java. The most interesting features of the cryptocurrency include its proof-of-importance (POI) algorithm (with the level of importance determined by how many coins a wallet stores and the number of transactions made to and from the wallet), an integrated P2P-secure multi-signature account and encrypted messaging system, and an Eigentrust++ reputation system which evaluates the quality of each client's contribution to maintain the network. NEM uses a client–server model where the NIS (NEM Infrastructure Server) runs independent of the NCC (NEM Community Client); the client is designed to run locally, in a web browser. Original announcement.
7. Dogecoin (DOGE) (7)
Dogecoin (DOGE) is an open-source, decentralised cryptocurrency forked from Luckycoin (a Litecoin fork) in December 2013. Its theme revolves around Shiba Inu, a well-known Japanese dog, which gave the coin its logo. Although Dogecoin started as a "joke currency", it quickly gained popularity, users and "miners" who generate new coins and help maintain the Dogecoin network. While the cryptocurrency uses the same hashing algorithm to process transactions as Litecoin (scrypt), it features a number of differences; notably faster block generation times (1 minute), uncapped total coin supply, and higher block reward (set to 10,000 DOGE per block in February 2015).
8. Gulden (NLG) (8)
Gulden (NLG), formerly known as Guldencoin, is a decentralised, open-source cryptocurrency forked from Litecoin in March 2014. It is intended as a national cryptocurrency of the Netherlands. Like Litecoin, it uses scrypt as the hashing algorithm, but the total intended coin supply is higher than Litecoin's (1.68 billion). Additionally, Gulden uses Kimoto's Gravity Well to adjust coin mining difficulty. The Subway franchise in the Dutch town of Leeuwarden was the first restaurant to accept Gulden, thus starting a tentative cryptocurrency revolution in the country. Original announcement.
9. Monero (XMR) (9)
Monero (XMR) is a decentralised open-source cryptocurrency forked from Bytecoin in April 2014. The coin's fundamental feature is privacy - it aims to be a digital medium of exchange with untraceable payments, unlinkable transactions and resistance to blockchain analysis. This is achieved thanks to a proof-of-work algorithm called CryptoNight, developed by the CryptoNote project. CryptoNote uses so-called "ring signatures", a sophisticated scheme that demands several different public keys from a group of users for verification. As such, the exact person behind a Monero transaction is not known; this results in considerable increase of privacy compared to Bitcoin and its forks. Original announcement.
10. Vcash (XVC) (10)
Vcash (XVC), formerly Vanillacoin (VNL), is a decentralised open-source cryptocurrency launched in December 2014. It was re-branded to Vcash in April 2016. Developed from scratch, it is a fast and privacy-oriented cryptocurrency, featuring ZeroTime (8-second transaction confirmations without the need of masternodes) and DarkPP (a framework for building decentralised DarkNet applications). The Vcash wallet application is a lightweight and easy-to-use cryptocurrency client with one special feature - a built-in command-line interface for passing Remote Procedure Call (RPC) commands. Vcash is a hybrid proof-of-work/proof-of-work cryptocurrency that allows both mining and staking with an annual interest of 0.7%. Original announcement.
11. CLAMS (CLAM) (11)
Clams (CLAM) is a decentralised, open-source cryptocurrency forked from Blackcoin in May 2014. Clams were initially distributed to 3,208,032 BTC, LTC and DOGE addresses based on the 12 May 2014 snapshots of the three respective blockchains. Each of these address received 4.60545574 CLAM. 63,381 addresses have been dug comprising 291,898.39 CLAM. If all the distributed CLAM were dug up, the total money supply would be 15,009,015.13. There was no proof-of-work stage and the network is secured by proof-of-stake only. Original announcement.
12. Deutsche eMark (DEM) (12)
Deutsche eMark (DEM) is a decentralised, open-source cryptocurrency forked from Litecoin in 2013. Originating in Germany, the project is a nostalgic attempt to re-create the country's old "Deutschmark" as a digital currency. It is a hybrid proof-of-work/proof-of-stake cryptocurrency with SHA-256 as hashing algorithm. A total of 20 billion coins will be produced, with the first 500 million proof-of-work coins mined by the year 2051, exactly 50 years after the introduction of the euro. Original announcement.
13. VERGE (XVG) (13)
Verge (XVG) (formerly DogecoinDark (DOGED)) is a decentralised, open-source cryptocurrency forked from Dogecoin in October 2014 and re-branded as VERGE in February 2016. The project exploited the growing popularity of the "fun" Dogecoin cryptocurrency while adding code to increase the coin's anonymity and privacy features, notably the network's ability to run on dedicated Tor nodes. Verge is a pure proof-of-work cryptocurrency that uses multiple hashing algorithms to mine new coins. The number of coins issued has been set to 9 billion during the first year and one billion per year thereafter. Original announcement.
14. Zcash (ZEC) (14)
Zcash (ZEC) is a decentralised, open-source cryptocurrency launched in October 2016 as a fork of Bitcoin. Its main focus is on privacy and anonymity of transactions. The project uses a technology called "Zerocash", a cryptographic currency protocol that does not reveal the origin, destination and the amount of the payment in the blockchain; instead, the correctness of the transaction is demonstrated via the use of a cryptographic concept called "zero-knowledge proof". Like Bitcoin, Zcash is a proof-of-work cryptocurrency generated by mining with a total supply set at 21 million coins. The block time is just 2.5 minutes (four times faster than Bitcoin's), but the reward is initially set to 12.5 ZEC per block (four times fewer than Bitcoin's). For mining, Zcash uses the Equihash hashing algorithm. Zcash is a heavily-funded corporate entity which has introduced a "founders' reward" where 10% of all mined coins is being distributed to the stakeholders in the Zcash Company.
15. AEON (AEON) (15)
AEON (AEON) is an open-source, decentralised cryptocurrency forked from Monero in June 2014. Like its parent, AEON uses the CryptoNight proof-of-work consensus mechanism and "ring signatures", thus making the transactions private and untraceable. The focus of the developers is to build an anonymous cryptocurrency that is faster, lighter and more mobile-friendly than Monero. Initial announcement.
16. Boolberry (BBR) (16)
Boolberry (BBR) is a decentralised, open-source cryptocurrency launched in 2014. The software behind the project is based on CryptoNote, a technology that provides much increased privacy and anonymity of transactions. Boolberry's benefits include: cryptography with ring signatures for unlinkability of transactions, separate wallet and daemon for extra security and cloud compatibility, flexible RPC-like network protocol with forward and backward capability for extended network interaction, and new ASIC-resistant hash algorithm called Wild Keccak. Boolberry enhances the CryptoNote technology to address several issues with other CryptoNote-based coins, such incomplete anonymity and block chain bloat. Original announcement.
17. BitShares (BTS) (17)
BitShares (BTS) is a brand of open-source software based on the as blockchain technology as used by Bitcoin. Unlike bitcoins, which do not produce any income for their owners, BitShare can be used to launch Decentralized Autonomous Companies (DACs) which issue shares, produce profits and distribute profits to shareholders. As such, BitShares is about making profitable companies that people want to own shares in, thus creating return for the shareholders. The first DAC launched by this proces was called BitSharesX, a decentralized asset exchange based in Hong Kong. BitShares was originally launched under the name of ProtoShares (PTS); it was later renamed to BitShares (PTS) and "reloaded" in November 2014 by merging several products into BitShares (BTS).
18. BlackCoin (BLK) (18)
BlackCoin (BLK), formerly BlackCoin (BC), is an open-source peer-to-peer cryptocurrency originally forked from Novacoin in February 2014. After a brief proof-of-work (scrypt) period, BlackCoin has switched to a pure proof-of-stake consensus mechanism which pays a compound annual interest of up to 1% to the stakeholders, depending on the amount of blackcoins staked. On the technical side, BlackCoin's confirmation times of just 64 seconds make it one on the fastest coins around. One interesting aspect of the project is its BlackCoinPool.com mining pool which mines other alternative cryptocurrencies and uses the proceeds to purchase blackcoins on the free market; this creates demand for the currency and it also stabilises its market rate. Original announcement
19. Bytecoin (BCN) (19)
Bytecoin (BCN) is a decentralised, anonymous cryptocurrency written from scratch and launched in July 2012. Its concept is based on the CryptoNote technology which focuses on privacy and anonymity of transactions. It comes with a number of unique features, such as ring signatures to make payments untraceable, an exchange protocol to make transactions unlinkable, and several others. Some other interesting features of the cryptocurrency include "egalitarian" proof-of-work mechanism and an analysis-resistant blockchain. Bytecoin is designed to be easily mined on an average personal computer while being resistant to mining with specialised ASIC hardware. The Bytecoin software is available in two variants - as a Bytecoin reference client that uses a command-line interface to manage transactions and to mine coins, or a Bytecoin wallet with an easy-to-use an intuitive graphical user interface. Original announcement.
20. Ripple (XRP) (20)
Ripple (XRP) is a native currency of Ripple, a payment protocol, currency exchange and remittance network. Launched in 2012, Ripple's mission is to enable secure, instant and nearly free global financial transactions. It is based around a shared, public database which uses a consensus process that allows for payments, exchanges and remittance in a distributed process. Despite being owned and operated by a company (based in the USA) and being the custodians of the majority of XRP tokens, the Ripple network is decentralised and it can operate even without the enterprise behind it. In the beginning, Ripple provided both web-based and desktop wallets clients for users to download; this was however discontinued in late 2016 in favour of an official Ripple gateway at GateHub.net. Unofficial Ripple desktop wallets are also available from third-party resources.
21. DigiByte (DGB) (21)
DigiByte (DGB) is a decentralised, open-source cryptocurrency and payment network launched in January 2014 as a fork of Bitcoin. Compared to its parent, DigiByte uses five highly advanced cryptographic algorithms, it provides faster transaction times with full confirmations every 3 minutes, and it can handle up to 140 transactions per second. The project plans to supply a total of 21 billion coins over 21 years. Original announcement.
22. Stratis (STRAT) (22)
Stratis (STRAT) is a blockchain platform launched in August 2016. It permits developers and enterprises to test and deploy Blockchain-based applications, equipping programmers with a Blockchain building interface using C# and the Microsoft .NET Framework. The cryptocurrency of the same name started life as a proof-of-stake token (using the X13 range of hashing algorithms), but it became a pure proof-of-stake coin at block 12,500. Stratis' initial wallet was a standard Qt-based application forked from Blackcoin, but the project also develops a custom, privacy-oriented wallet (called Breeze) which uses TumbleBit, payment hub that allows parties to make fast, anonymous, off-blockchain payments through an untrusted intermediary called the Tumbler. Initial announcement.
23. GoldCoin (GLD) (23)
GoldCoin (GLD) is a decentralised open-source cryptocurrency forked from Litecoin in May 2013. It is a proof-of-work coin using "Golden River" (a variant of scrypt developed in house) as its hashing algorithm. The philosophy behind the coin's generation was modeled on the real-life finite supply of physical gold which is to be exhausted after 100 year of mining, creating some 123 million of goldcoins in the process. While GoldCoin wasn't pre-mined, it was launched with a highly disproportionate reward structure that dramatically favoured insiders and early miners. Original announcement.
24. Golem (GNT) (24)
Golem (GNT) is a cryptocurrency token issued on the Ethereum network by the project of the same name. The goal of the Golem project is to build a global, open-sourced and decentralised supercomputer. It describes itself as the "Airbnb of computing", a decentralized sharing economy of computing power where anyone can make money "renting out" their computers or developing and selling software. Unlike many popular cryptocurrencies, Golem is not mined or staked; instead, the entire complement of 1 billion tokens, of which 18% were reserved for the project's founders and developers, were issued at the launch. Original announcement
25. Bitmark (BTM) (25)
Bitmark (BTM) is a decentralised, open-source cryptocurrency forked from Bitcoin in July 2014. The project's main goals are to maintain a stable cryptographic currency network and to promote wide-scale adoption of the coin through an initiative called "marking".

Steemit, whose chief technology officer is BitShares founder Daniel Larimer, promises a fast-paced development, including a user-friendly graphical wallet client. Original announcement.
35. Ethereum (ETH) (35)
Ethereum (ETH), launched in July 2015 after a successful fund-raising period, is an open-source, decentralised cryptocurrency platform with "smart contracts", a set of scripts which run on top of Ethereum's blockchain and which automatically enforce contracts and agreements. It is also a development platform that makes it easy to build decentralised applications using Ethereum's own scripting language. The currency behind the Ethereum network is called "Ether". While the developers intended Ether to be just a token (rather than currency) to pay for computation and network maintenance, Ether (often referred to as "Ethereum") is actively traded on many digital currency exchanges. Original announcement.
36. Decred (DCR) (36)
Decred (DCR) is a decentralised, open-source cryptocurrency launched in February 2016 by a group of former Bitcoin developers. The new project aimed to address concerns over the increasing centralization of power in Bitcoin and a growing conflict of interest between the user community and those funding the Bitcoin project. On the technical front, Decred is a hybrid proof-of-work/proof-of-stake (PoW/PoS) cryptocurrency which can be both mined (using the BLAKE-256 hashing algorithm) and staked. The project offers a choice between a graphical web-based wallet and a command-line client for all popular operating systems, including the BSDs. Original announcement.
37. DigitalNote (XDN) (37)
DigitalNote (XDN) is a decentralised, open-source cryptocurrency launched as "duckNote" in May 2014 and renamed to DarkNote in September 2014 and again to DigitalNote in June 2015. It was originally forked from Bytecoin. DigitalNote's main focus is on privacy and anonymity of transactions; this is achieved thanks to a technology called CryptoNote. CryptoNote's two main features are "ring signatures" (where several users sign a payment message, making it impossible to determine who exactly received the payment) and "unlinkable transactions" (thanks to automatic generation of unique single-use private keys). Besides serving as a payment network, DigitalNote also provides an ability to send encrypted messages to anyone in the world. Original announcement.
38. LeafCoin (LEAF) (38)
Leafcoin (LEAF) is a decentralised, open-source digital currency forked from Bitcoin in early 2014. The project launched with a mission to help funding the preservation and re-forestation of rainforests through Leafcoin Foundation. Original announcement.
39. Auroracoin (AUR) (39)
Auroracoin (AUR) is a decentralised, open-source cryptocurrency launched in January 2014 as a fork of Litecoin. It was intended as a national cryptocurrency of Iceland and distributed to the citizens of the country to use as an alternative payment option that could circumvent Iceland's foreign exchange restrictions introduced after the 2008 financial crisis. In March 2016, Auroracoin was re-based on DigiByte, replacing the original scrypt hashing algorithm with a multi-algo combination of Grøstl, Qubit, scrypt, SHA-256 and Skein. Certain other parameters were also updated, including the block confirmation time which was decreased to 61 seconds. Original announcement.
40. IOTA (IOT) (40)
41. Lisk (LSK) (41)
42. CannabisCoin (CANN) (42)
CannabisCoin (CANN) is a decentralised, open-source cryptocurrency forked from Bitcoin and Peercoin in May 2014. It was conceived as a payment solution for marijuana dispensaries, retailers and merchants and it is backed by marijuana wherever it is accepted. Technically, CannabisCoin is a proof-of-work cryptocurrency which uses the ASIC-resistant X11 hashing algorithm and Kimoto's Gravity Well (KGW) for adjusting the mining difficulty. The total coin supply is capped at 92 million. Original announcement.
43. BitcoinDark (BTCD) (43)
BitcoinDark (BTCD) is a decentralized cryptocurrency, forked from NovaCoin in 2014, providing groundbreaking privacy and anonymity. It features two unique characteristics: Teleport, which allows for anonymous transfer of funds by cloning and exchanging standard denominations of currency, and Telepathy, which encrypts communication sent across the network and masks the other user's IP address. Unlike many other cryptocurrencies, BitcoinDark encourages ASIC mining (i.e. generating coins with specialist hardware), which is a much more energy efficient way of generating coins than CPU/GPU mining. Original announcement.
44. Cardano (ADA) (44)
Cardano is an open-source project creating a decentralised platform which includes a cryptographic currency unit called ADA (equaling one million Lovelaces) and which allows complex, programmable transfers of value. The principal software stack powering the platfrom is called "Cardano Settlement Layer" (cardano-sl, written in Haskel), while its graphical desktop wallet client is known as "Daedalus". Cardano's ADA is a proof-of-stake cryptocurrency which uses a custom algorithm called "Ouroboros". The software is developed by Input Output Hong Kong (IOHK) and the entire project is managed by Cardano Foundation, a non-profit organisation.
45. Curecoin (CURE) (45)
Curecoin (CURE) is a decentralised, open-source cryptocurrency forked from Litecoin and launched in May 2014. It is a hybrid proof-of-work/proof-of-stake coin which means that curecoins can be both mined (using the SHA-256 hashing algorithm) and minted (through the staking process). The project's mission is to take advantage of the available computing power that mines/mints curecoins to help with the process of protein folding (via Stanford University's Folding@home distributed computing project) and thus indirectly help researchers who work on curing diseases, such as cancer or Alzheimer's. Original announcement.
46. Ethereum Classic (ETC) (46)
Ethereum Classic (ETC) is an open-source, decentralised cryptocurrency platform announced in July 2015 when the original Ethereum (ETH) blockchain was hard-forked following a security breach. Although the hard fork option was excessively debated and eventually approved by the Ethereum Foundation, many users felt that this move represented censorship and interference with a project that was supposed to be "decentralised". This disagreement brought about the birth of Ethereum Classic, a project whose main goal is to ensure the survival of the original Ethereum blockchain. As a result, the currency of Ethereum (called "ether") now exists in two forms, ETC and ETH, with both being actively traded on a number of cryptocurrency exchanges. The Original announcement.
47. NAV Coin (NAV) (47)
NAV Coin (NAV) is a decentralised, open-source cryptocurrency launched in July 2014. It was rebranded several times - from Summercoin, which was a fork of Bitcoin, to Navajocoin, Navajo Coin and finally NAV Coin. After 100,000 proof-of-work blocks (using the X13 collection of hashing algorithms), the cryptocurrency has switched to a pure proof-of-stake (PoS) consensus, with a diminishing rate of PoS interest that started at 20% and ended at 5% per annum starting from the third year on. The project's primary focus is on creating a cryptocurrency with enhanced privacy and anonymity of transactions. Original announcement.
48. Komodo (KMD) (48)
Komodo (KMD) is a decentralised, open-source cryptocurrency launched in September 2016. It has evolved from BitcoinDark (BTCD) and is developed by the same developer ("jl777"), but the underlying software was forked from Zcash and the new cryptocurrency runs on the SuperNET platform, using SuperNET's infrastructure and software applications. Focusing on privacy and anonymity of transactions, Komodo deploys a "delayed proof-of-work" (dPoW) consensus mechanism which relies on pre-voted notary nodes and which is secured by the Bitcoin (BTC) network. It uses Zcash's "zero knowledge proof" to (optionally) make transactions anonymous and untraceable. Initial announcement.
49. Myriad (XMY) (49)
Myriad (XMY), previously known as Myriadcoin (MYR), is a decentralised, open-source cryptocurrency forked from Zetacoin in February 2014. Myriad's most interesting innovation is the ability to mine the coin using five different hashing algorithms - Grøstl, scrypt, SHA-256, Skein, Yescript. As such, it is available for mining by traditional methods (CPU and GPU) as well as specialised mining using ASIC hardware. This multiple hashing algorithm was designed to make Myriad mining fair and accessible to all and to encourage even distribution of coins. Original announcement.
50. YoCoin (YOC) (50)
YoCoin (YOC), also spelt as "Yocoin" or "YOcoin", is an open-source, decentralised cryptocurrency announced in December 2015 as a fork of Bitcoin. It is a proof-of-work coin which is generated by "mining", with scrypt as the hashing algorithm. The coin was launched publicly after a total of 15% of total supply was pre-mined; this was meant to be used only for giveaways, swap handling and YoCoin promotions. Original announcement.
51. Zclassic (ZCL) (51)
Zclassic (ZCL) is a decentralised, open-source cryptocurrency launched in November 2016 as a fork of Zcash. It comes with the exact same parameters as its parent (21 million coins, 2.5 minute block time, initial reward of 12.5 ZCL per block, Equinox hashing algorithm), but it does away with the 20% "founders' reward" fee introduced by the heavily-funded Zcash project. It also removed Zcash's "slow start" to mining where the initial reward to miners was set to a very low value for the first month. Like Zcash, Zclasic focuses on transaction privacy and anonymity, using the Zclassic is a pure community effort with no pre-mine or insta-mine and no reward for the developers. Original announcement.
52. Blocknet (BLOCK) (52)
Blocknet is a project attempting to create a peer-to-peer protocol between nodes on the blockchains of participating cryptocurrencies. Blocknet was initiated by XCurrency (XC), but it was later extended by several other cryptocurrency projects all of whom have representation on the Blocknet Foundation's Board. This groundbreaking initiative enables open-ended communication and delivery of services between users of participating cryptocurrencies, thus effectively uniting the community that has been fractured by hundreds of cryptocurrency projects. To maintain Blocknet's network and services, the project issues its own "tokens of value" as a reward to those who participate in maintaining a healthy network. This makes Blocknet (BLOCK) a proof-of-stake cryptocurrency which is actively traded on a number of popular altcoin exchanges. Original announcement.
53. Europecoin (ERC) (53)
Europecoin (ERC) is a decentralised, open-source cryptocurrency forked from Novacoin in May 2014. After two weeks of mining which generated some 137 million coins, Europecoin became a pure proof-of-stake cryptocurrency with a variable interest (from 2.5% to 15% per year) depending on the maturity of the coins held. A total of 1% of the coins were pre-mined. In July 2016, the coin was relaunched under a new development team and as a proof-of-work cryptocurrency based on Bitcoin. Original announcement.
54. NuBits (NBT) (54)
NuBits (NBT) is a decentralised open-source cryptocurrency launched in late 2014 by Peercoin developer Jordan Lee. Unlike most other cryptocurrencies, NuBit coins are not mined, but rather issued by the project's shareholders whose primary goal is to maintain a 1:1 NuBit peg to the US dollar. In the case of hyperinflation of the US dollar, the shareholders can vote to peg NuBits to a different currency or to a basket of commodities. By creating more coins to keep prices down and by increasing interest rates on parked coins to restrict supply, the NuBit projects hopes to have created a stable cryptocurrency with limited volatility.
55. Dash (DASH) (55)
Dash (DASH) is a decentralised, open-source, digital cryptocurrency project forked from Litecoin in January 2014. Compared to Litecoin, Dash offers stronger transaction privacy and anonymity, while its software is more resistant to mining with specialist hardware. Better privacy is achieved through a technology called Darksend, a coin-mixing service that combines identical inputs from multiple users into a single transaction with several outputs which obfuscates the flow of funds. Dash has also developed and implemented a hashing algorithm called X11 which uses a sequence of 11 rounds of hashing for its proof-of-work consensus mechanism. To adjust mining difficulty over time, Dash uses an algorithm called Dark Gravity Wave, also developed in-house. The cryptocurrency project was formerly known as Darkcoin (DRK), but it was rebranded to Dash in March 2014. Original announcement.
56. Orbitcoin (ORB) (56)
Orbitcoin (ORB) is a decentralised, open-source cryptocurrency launched in July 2013 as a fork of Novacoin. It is a hybrid proof-of-work/proof-of-stake coin with a total coin supply of just 3.77 million units. As such, orbitcoins can be both mined (using the NeoScrypt hashing algorithm) and minted (SHA-256) - both methods carry a fixed reward of 1 ORB. Other features of the cryptocurrency include: one-minute combined block target, time warp and "instamining" protection, advanced checkpointing against 51% attacks, and very low transaction fees. Original announcement.
57. PascalCoin (PASC) (57)
PascalCoin (PASC) is a decentralised, open-source cryptocurrency launched in August 2016. It was written from scratch in Pascal. Unlike most other cryptocurrencies, PascalCoin is designed to work without an operations history (i.e. locally stored blockchain), yet it is still able to control double spending and check balances. Instead of storing balances on the blockchain, PascalCoin offers a safebox system similar to a bank account and complete with a short, easy-to-remember account number. PascalCoin is generated by proof-of-work "mining", with an average block time of 5 minutes and the initial reward of 100 PASC (halving roughly every four years). Initial announcement.
58. CloakCoin (CLOAK) (58)
CloakCoin (CLOAK) is a decentralised, open-source cryptocurrency launched in June 2014 and re-launched in October 2016 under a new management and based on Bitcoin Core. It was one of the first coins focusing on privacy and anonymity of transactions and this quest was further enhanced after the relaunch as the developers implemented an off-chain peer-to-peer coin mixing arrangement called Enigma, provided by a Tor-like routing system named CloakShield. CloakCoin is a pure proof-of-stake (PoS) cryptocurrency that offers an interest of 6% per annum on staked coins, but users are also eligible to a share in the network's 1.8% transaction fee for their support towards Enigma transactions. Original announcement.
59. VeriCoin (VRC) (59)
VeriCoin (VRC) is a decentralised and open-source cryptocurrency forked from Blackcoin in May 2014. It features a variable interest rate which fluctuates depending on how many coins are "staking"; as more coins are used to support (stake) the network, the interest rate climbs.The project has developed several innovative features into its software, such as VeriBit - a service that allows the user to pay for items with VeriCoin wherever Bitcoin is accepted, and VeriSMS - a text-based gateway and wallet system that enables VeriCoin users to make transactions by sending SMS messages. Original announcement.
60. MintCoin (MINT) (60)
MintCoin (MINT) is a decentralised, open-source cryptocurrency forked from Novacoin in February 2014. The project used the proof-of-work mechanism to generate coins by "mining" during the first five weeks of its existence before becoming a pure proof-of-stake cryptocurrency. The "staking" process uses a variable interest rate at 20% the first year. After that it decreases by 5% per year until the 4th year when it reaches a constant annual interest rate of 5%. Since the vast majority of the coins are and will be generating by "staking", it is considered an energy-efficient coing, compared to Bitcoin and other proof-of-work cryptocurrencies. Original announcement.
61. Bitcoin Gold (BTG) (61)
Bitcoin Gold (BTG) was launched on 12 November 2017 by hard-forking the original Bitcoin (BTC) blockchain at block number 491,407 and switching to a new proof-of-work algorithm (Equihash). This has created a bifurcation of the Bitcoin blockchain. The original Bitcoin blockchain continues on unaltered, but a new branch of the blockchain has split off from the original chain. This new branch is a distinct blockchain with the same transaction history as Bitcoin up until the fork, but then diverges from it. As a result of this process, a new cryptocurrency was born. The purpose of Bitcoin Gold is to make Bitcoin mining decentralised and available to anybody; this is in contrast to Bitcoin (BTC) mining which has been dominated by large mining farms running highly specialised equipment.
62. BitSwift (SWIFT) (62)
BitSwift (SWIFT) is a decentralised, open-source cryptocurrency forked from Novacoin and launched in October 2014. It is a pure proof-of-stake (PoS) coin, with the annual PoS interest set at 3%. The project's developers plans include, among other features, seamless integration with fiat currencies which would enable worldwide money transfers at zero cost. The BitSwift cryptocurrency and its blockchain run on the BlockNet platform. Original announcement.
63. Qora (QORA) (63)
Qora (QORA) is a decentralised open-source cryptocurrency launched in April 2015 and written from scratch, in Java. As a pure proof-of-stake cryptocurrency, Qora relied on initial public offering for the supply and distribution of the 10 billion coins in existence. Besides a unique wallet client, the cryptocurrency also offers a number of innovative features, such as password-protected wallets that can be regenerated from seeds, differential block times which allow addresses to generate blocks after just ten confirmations, an ability to register a key-value pair that can be used for various purposes and even traded, encrypted messenger service or data storage. Original announcement.
64. StealthCoin (XST) (64)
StealthCoin (XST) is a decentralised, open-source cryptocurrency forked from Novacoin in July 2014. As its name suggests, the project attempts to provide a complete anonymity solution for cryptocurrencies. This is achieved by using a concept called StealthAddress, a cryptographic blockchain obfuscation technique where innumerable destination addresses can be created from each public receiving address; the destination addresses can not be linked to each other or to the public receiving address. Another interesting feature of the cryptocurrency is StealthText, a multi-platform anonymous cryptographic SMS transaction sending technology. StealthCoin has a fair distribution with nearly four hours of low block rewards, a small premine of 1%, and the long-term energy efficiency of proof-of-stake minting. Original announcement.
65. Titcoin (TIT) (65)
Titcoin (TIT) is a decentralised, open-source cryptocurrency launched in June 2014 as a customised fork of Bitcoin. It was designed specifically for the adult entertainment industry where privacy and anonymity are key consumer factors, while also giving consumers the ability to make discreet micropayments that carry extremely low transaction fees. Technically, Titcoin is similar to Bitcoin with some key differences, such as improved transaction speeds, modified network difficulty adjustment, higher number of coins rewarded per block (69 TIT), and higher total supply of coins (69 million TIT compared to 21 million BTC). Titcoin is notable for being the first altcoin fully recognized as a legitimate form of currency by a major industry trade organization. Original announcement.
66. Feathercoin (FTC) (66)
Feathercoin is an open-source digital currency forked from Litecoin in 2013. The project's main innovation is NeoScrypt, a processor-intensive hashing algorithm that makes it difficult to mine coins with specialist hardware, such as ASIC. Another interesting feature of Feathercoin is the implementation of "advanced checkpointing" in its blockchain to guard against the "51% attack", a known vulnerability in the Bitcoin software. The developers of Feathercoin have been experimenting with additional software and hardware projects not found in most other cryptocurrencies, e.g. development of ATMs and Point-of-Sales equipment, T-shirt wallets, laser-etched physical coins and several Raspberry Pi-based projects. Original announcement.
67. Bitcoin Cash (BCH) (67)
Bitcoin Cash (BCH) was created on 1 August 2017 by hard-forking the original Bitcoin (BTC) blockchain at block number 478,558. At this point the Bitcoin blockchain split into two separate chains, with the Bitcoin Cash (BCH) token effectively becoming a new "altcoin" (even though the idea was to make Bitcoin Cash the dominant form of Bitcoin). The reason for the hard fork was a disagreement among the leading developers on the issue of scaling the Bitcoin (BTC) software which, in its original form, could no longer cope with the ever increasing number of transactions. The new Bitcoin Cash (BCH) software has solved the scaling problem by increasing the block size to 8 MB (up from 1 MB in Bitcoin), thus improving the transaction speed dramatically. The Bitcoin Cash software does not have a centralised development system and it relies on several separate development teams which provide wallet clients; these include Bitcoin ABC, Bitcoin Classic, Bitcoin Unlimited and Bitcoin XT. Original announcement.
68. e-Gulden (EFL) (68)
e-Gulden (EFL), also known as Electronic Gulden, is an open-source, decentralised cryptocurrency forked from Litecoin in March 2014. It is intended as the national cryptocurrency of the Netherlands, bringing back the nostalgic feeling of the times before the country adopted the common European currency. Besides providing a digital payment solution, the project also has advocacy goals, promoting saving over consumption and attempting to preserve scarce natural resources. e-Gulden was heavily pre-mined, with 50% of the total coin supply retained by the e-Guilder Foundation. Original announcement.
69. Bata (BTA) (69)
Bata (BTA) is a decentralised, open-source cryptocurrency forked from Litecoin and launched in May 2015. The project's focus is to provide strong privacy and transaction anonymity features by integrating its wallet client with anonymous I2P and Tor networks. Like its parent, Bata is a proof-of-work coin that uses the scrypt hasing algorithm for "mining", although the total coin supply has been limited to just 5 million (less than a quarter of Litecoin's). The cryptocurrency derives its name fromt the word "barter". Original announcement.
70. DNotes (NOTE) (70)
DNotes (NOTE) is a decentralised, open-source cryptocurrency forked from Litecoin in February 2014. Compared to its parent, it has only a few minor modifications, such as the use of Kimoto's Gravity Well (patched for the "time warp" issue), a total supply of 500 million coins, and an annual 5% block reward reduction for coin miners. Besides developing the cryptocurrency, the project has also launched a number of unique initiatives; this includes attempts to attract more women to the cryptocurrency world by giving away free DNotes, programs offering solutions for student debt, and provisions of various savings incentives for the unbanked, children, and retirees. Original announcement.
71. PotCoin (POT) (71)
PotCoin (POT) is a decentralised, open-source cryptocurrency forked from Litecoin in January 2014. It was created with the goal of becoming the standard form of payment for the legalised marijuana industry. Technically, PotCoin is almost identical to Litecoin, with just a few differences: a shorter block generation time, quicker halving schedule, and a higher maximum number of coins. As a result of its name and nature, the cryptocurrency attracted a fair amount of attention in mainstream media and, unlike most cryptocurrencies, PotCoin was deemed sufficiently notable to keep a Wikipedia page. Original announcement.
72. MazaCoin (MZC) (72)
MazaCoin (MZC) is a decentralised open-source cryptocurrency forked from Zetacoin in March 2014. It was conceived as a result of signing a memorandum of understanding with the Oglala Sioux Tribe, a native American tribe in North America. An inscription was placed into the genesis block to remind the users about the reasons behind creating MazaCoin. It reads: "The Black Hills are not for sale. 1868 is the LAW!", referring to the Sioux treaty with the US government signed in 1868. The cryptocurrency uses the proof-of-work consensus mechanism, with a total of 2.4192 billion coins mined during the first five years, followed by 1 million coins per year thereafter. Original announcement.
73. Monacoin (MONA) (73)
Monacoin (MONA) is a decentralised, open-source cryptocurrency forked from Litecoin and launched in January 2014 in Japan. Compared to its parent, the total coin supply is set to four times that of Litecoin (105 million), while the mining difficulty is re-targeted every block using the Dark Gravity Wave difficulty algorithm. The coin's block time generation of 1.5 minutes is faster than Litecoin's 2.5 minutes. Monacoin was launched with a 0% pre-mine. Original announcement.
74. vTorrent (VTR) (74)
vTorrent (VTR) is an open-source, decentralised cryptocurrency launched in late 2014 as a fork of Shadow (SDC). The most distinctive (planned) feature of the software project was the incorporation of a BitTorrent client into the vTorrent wallet, thus trying to appeal to the many BitTorrent users while making the currency transactions more anonymous and difficult to trace. On a technical side, the coin was launched using the proof-of-work consensus mechanism and scrypt as the hashing algorithm to generate the initial pool of tokens (there was a 3% pre-mine), but was gradually moving to a proof-of-stake phase with a 5% interested rate payed to the "stakers". The vTorrent wallet is an advanced graphical software with some interesting features, such as anonymous chat, blockchain explorer and even an option to trade cryptocurrencies on the Bittrex exchange. Original announcement.
75. Blakecoin (BLC) (75)
Blakecoin (BLC) is a decentralised, open-source cryptocurrency forked from Bitcoin in October 2013. It was the first cryptocoin project to employ BLAKE-256 (a candidate for the US National Institute of Standards and Technology hash function competition to become the new SHA-3 standard) as its hashing algorithm. BLAKE-256 is reportedly faster than the SHA-256 algorithm used by Bitcoin. It also employs a custom asymmetrical difficulty re-target algorithm. The reward for mining Blakecoin is set to 25 blakecoins plus inflation which is calculated as square root of (difficulty * block height). Original announcement.
76. Florincoin (FLO) (76)
Florincoin (FLO) is a decentralised cryptocurrency forked from Litecoin in July 2014. Like its parent, it is a proof-of-work coin that uses the scrypt hashing algorithm to mine coins and process transactions. However, the project has implemented or has plans to implement several interesting additions, such as very fast transaction times (40 seconds), a decentralised messaging system, and a storage/backup database (called Alexandria) which the developers plan to use to power decentralised applications of the future. Florincoin was launched with a 0% pre-mine. Original announcement.
77. Zeitcoin (ZEIT) (77)
Zeitcoin (ZEIT) is a decentralised open-source cryptocurrency launched in March 2014 as a fork of Peercoin. It began life as a hybrid proof-of-work/proof-of-stake coin that used the scrypt hashing algorithm for the initial generation of zeitcoins. Two months later the coin became a pure proof-of-stake (PoS) coin, initially paying an annual PoS interest of 25%, but this is expected to drop by 5% a year and eventually stay at 5% of annual PoS interest after year four. The coin features fast confirmation times of two minutes. A total of 1% of zeitcoins were pre-mined and allocated for bounties and software development. Original announcement.
78. Anoncoin (ANC) (78)
Anoncoin (ANC) is a digital cryptocurrency, created in June 2013 as a fork of Bitcoin, with the focus on privacy and anonymity of its users. The software's main feature is the built-in support for two decentralised networks (I2P Darknet and Tor), thanks to which it is impossible to determine the IP address of the user making a transaction. To enhance the user's anonymity even further, the Anoncoin developers plan to implement a new feature called "Zerocoin", which will allow users to make untraceable and unlinkable transactions. With I2P, Tor and Zerocoin, Anoncoin will provide one of the most anonymous cryptocurrencies on the market. As with most cryptocoins, the project's computing network is maintained by "miners", running the Anoncoin software, who generate new coins by processing transactions into blocks. Original announcement
79. Earthcoin (EAC) (79)
Earthcoin (EAC) is a decentralised, open-source cryptocurrency forked from Litecoin in December 2013. The project has implemented a special payout system that depends on various aspects of the earth and its movement, with special bonuses awarded at the completion of seasons, moon cycles and calendar months. Earthcoin delivers extremely fast transaction speeds of 30 seconds. Two percent of the total coin supply were pre-mined and used for promotions, giveaway, bounties, development and long-term support of the project. Original announcement.
80. Unobtanium (UNO) (80)
Unobtanium (UNO) is a decentralised open-source cryptocurrency forked from Bitcoin in 2013. It derives its name from a fictional engineering and scientific term that describes an extremely rare or impossible-to-obtain element. Members of the UNO community often measure the amount of their UNO cryptocurrency holdings in kilograms rather than coins. Unobtanium is a rare, SHA-256 proof-of-work cryptocurrency with the maximum supply of just 250,000 coins. With 0% pre-mining and no replacements for lost unobtaniums, it is considered a "fair-mined" cryptocurrency, with scarcity being its most distinguished feature. Original announcement.
81. Vertcoin (VTC) (81)
Vertcoin (VTC) is a decentralised open-source cryptocurrency forked from Bitcoin and launched in early 2014. It attempts to negate some of Bitcoin's shortcomings, namely circumvent the effect of ASIC (Application Specific Integrated Circuit) computing which tends to monopolise coin mining. As such, it claims to be able to stop the infamous 51% attack, a known vulnerability in Bitcoin. This feature is achieved through the use of a memory-intensive hashing algorithm called "Adaptive N-Factor" (or "Scrypt Adaptive N-Factor", or "scrypt-n" for short) which discourages the use of ASIC systems. The coin was launched with no pre-mining, except for three blocks to test the software. Original announcement.
82. Burstcoin (BURST) (82)
Burstcoin (BURST) is an open-source, decentralised cryptocurrency launched in August 2014. It is based on Nxt, but it replaces the parent's proof-of-stake way of generating coins with a new mining concept called "proof-of-capacity". Proof-of-capacity uses the miners' unused hard drive space, rather than their processors or graphics cards, to generate new coins. Besides developing a cryptocurrency, the project also offers a decentralised marketplace and other features. The Burstcoin wallet is a Java-based client that runs locally inside any web browser. Original announcement.
83. Factom (FCT) (83)
Factom (FCT) is a decentralised, open-source cryptocurrency platform launched in September 2015. Unlike Bitcoin whose blockchain is used for currency transactions only, Factom comes with an enhanced blockchain that allows anyone to add new entries to the blockchain, including contracts and agreements in the form of scripts and applications. In other words, Factom creates an additional data layer (a record-keeping system) on top of the blockchain. As an incentive to maintain the network and to distribute the blockchain, Factom issues "factoids", or tokens that can be traded on cryptocurrency exchanges. Original announcement.
84. Namecoin (NMC) (84)
Namecoin (NMC) is a decentralized open-source cryptocurrency forked from Bitcoin in 2011. It uses the same proof-of-work algorithm and is limited to 21 million coins, but it offers several innovation, such as the ability to store data within its blockchain or merged mining. Namecoin's flagship use-case is the censorship resistant top level domain .bit, which is functionally similar to .com domains but independent of ICANN, the main governing body for domain names. In early 2014 the project released FreeSpeechMe, a Firefox plug-in that allows automatical resolution of .bit addresses. Original announcement.
85. GoldBlocks (GB) (85)
GoldBlocks (GB) is a decentralised, open-source cryptocurrency forked from BlackCoin in May 2016. It's a hybrid proof-of-work/proof-of-stake (PoW/PoS) coin which can be either "mined" by a computer or "minted" through a process called "staking". The PoW part of the coin uses the X11 hashing algorithm (11 rounds of scientific hashing functions that include blake, bmw, groestl, jh, keccak, skein, luffa, cubehash, shavite, simd and echo) with a 60-second block time and a total coin supply of 24.7 million. The coin's PoS method offers a 10% annual interest on staked coins, with the total supply capped at 50 million coins. Original announcement.
86. Gridcoin (GRC) (86)
Gridcoin (GRC) is a decentralised, open-source cryptocurrency forked from Litecoin in 2013. Originally it was a proof-of-stake currency with scrypt as its hashing algorithm, but the original client is now being discontinued in favour of a new client called "Gridcoin Research", launched in October 2014. The most distinguishing feature this cryptocurrency is a consensus mechanism called "Proof of Research" which is able to cryptographically verify BOINC (Berkley Open Infrastructure for Network Computing) computing tasks and which rewards the client with a cryptographic token for completing the task. BOINC currently hosts a series of scientific projects including cancer research, drug candidate testing, high-energy physics, space mapping and disease control. Original announcement.
87. Groestlcoin (GRS) (87)
Groestlcoin (GRS) is a decentralised, open-source cryptocurrency forked from Bitcoin in March 2014. The project's focus is to enable anybody with a standard computer to mine coins, using either the computer's central processing unit (CPU) or its graphcs processing unit (GPU). Groestlcoin is a hybrid proof-of-work/proof-of-stake coin which uses the ASIC-resistent Grøstl hashing algorithm to complete proof-of-work blocks. Starting at block 150,000, coins can also be generated by "staking" at a 2% annual interest. The total number of coins was set to 105 million, with the initial block reward at 25 GRS; this is reduced by 6% every 10,080 blocks. The block time is 60 seconds, while the difficulty is recalculated after each completed block of transactions. Original announcement.
88. Peercoin (PPC) (88)
Peercoin (PPC) is a decentralised open-source cryptocurrency forked from Bitcoin in 2012. Peercoin's major distinguishing feature, compared to Bitcoin and most other cryptocurrencies, is that it uses a hybrid proof-of-stake/proof-of-work system as its consensus mechanism, thus reducing the risk of certain network vulnerabilities. Other characteristics include increased energy efficiency during the mining process, no hard limit on the total number of coins issued, a 1% annual inflation, and fixed protocol-defined transaction (at 0.01 PPC) fees which are destroyed to offset the inflation rate and to self-regulate transaction "spam" by eliminating low-value payments. Original announcement.
89. Viacoin (VIA) (89)
Viacoin (VIA) is a decentralised, open-source cryptocurrency forked from Bitcoin in July 2014. The project's primary goal is to create a blockchain protocol, called "ClearingHouse", which would allow the building of fully decentralized exchanges and issuing of new currencies, as well as asset tracking, betting, digital voting, reputation management and going as far as allowing to form the basis of fully decentralized marketplaces. According to the project's management, these kind of services (or "sidechains") often face resistance from core Bitcoin developers when attempting to buil them on top of Bitcoin's own blockchain - hence the reason for launching the new cryptocoin. Viacoin's launch was accompanied by much attention in the media - especially because of the coin's explosive price growth (VIA reached market capitalisation of US$1 million in just a few days of trading), but also because the project was joined by Peter Todd, a well-known and experienced Bitcoin developer. Original announcement.
90. Worldcoin (WDC) (90)
Worldcoin (WDC) is a decentralised open-source digital currency secured by cryptography. Forked from Bitcoin in 2013, the project's primary goal is to create a business-friendly payment system that would become the choice for merchants and consumers for everyday transactions. Worldcoin prides itself for having very fast transaction speeds, fully confirmed in less than 60 seconds. The coin's creators hope to sponsor world-changing projects, starting with an installation of a Worldcoin community-sponsored clean water well in Kenya. Original announcement.
91. Quark (QRK) (91)
Quark (QRK) is an experimental digital currency that enables instant payments to anyone, anywhere in the world. Quark uses peer-to-peer technology to operate with no central authority; managing transactions and issuing money are carried out collectively by the network. Quark's most distinguished feature is its focus on transaction security as it uses nine rounds of secure hashing (three of which use random hashing algorithms) from six different hashing algorithms to encode Quark transactions. Original announcement.
92. ARCHcoin (ARCH) (92)
ARCHcoin (ARCH) is a decentralised, open-source cryptocurrency launched in October 2014 in Portugal. It is a pure proof-of-stake coin which pays a variable interest rate of between 3 - 20%, depending on the state of the ARCHcoin network. The project's main goal is to develop a centralised business model on top of a decentralised blockchain - by offering a platfrom for various investment niches (ARCHprojects) and allowing integration of advanced blockchain services. Original announcement.
93. Breakout Coin (BRK) (93)
Breakout Coin (BRK) is a product of Breakout Gaming which is a new, globally accessible online gaming entertainment company that plans to provide poker, sports wagering, casino games, fantasy sports, and other popular gaming options. The original currency, Breakout Coin, was later integrated into a unique multi-currency wallet system called "Breakout Chain". While Breakout Coin (BRK) remains the principal currency for Breakout Gaming, there are also Breakout Stake (BRX) and Sister Coin (SIS) which serve to secure the ledger through a combined proof-of-stake (PoS) and proof-of-work (PoW) model. The PoS system uses Breakout Stake as the stake, minting Breakout Coin. As such, the Breakout Stake money supply will never increase, whereas the Breakout Coin money supply increases at a rate of approximately 5% per year. Breakout Chain’s PoW system produces Sister Coin as an incentive to miners. Original announcement.
94. Carboncoin (CARBON) (94)
Carboncoin (CARBON) is a decentralised, open-source cryptocurrency forked from Luckycoin (which was, in turn, forked from Litecoin) in February 2014. It is designed to fund the planting of millions of trees worldwide to address the problem of soaring emissions. The project's goal is to eliminate coin mining for profit, an aspect of Bitcoin responsible for harming the environment through excessive and unproductive use of electricity and resources. Original announcement.
95. EverGreenCoin (EGC) (95)
EverGreenCoin (EGC) is a decentralised, open-source cryptocurrency forked from Bitcoin and inaugurated in December 2015. It started life as a proof-of-work (PoW) coin using the X15 spectrum of hashing algorithms for generating coins, but it was converted into a pure proof-of-stake (PoS) currency some six month after its launch. It offers a 7% annual interest on staked coins. EverGreenCoin's parameters make it a faster and more environmentally-friendly cryptocurrency than Bitcoin. Initial announcement.
96. Neos (NEOS) (96)
Neos (NEOS) is a decentralised, open-source cryptocurrency forked from Bitcoin in August 2014. It is a proof-of-work coin that uses the same hashing algorithm as Bitcoin (SHA-256), but it also has a number of interesting features, such as a theft recovery mechanism. Other features of the Neos wallet client include in-wallet trading (one-click withdrawal, mass order cancellation, one-click deposit); in-wallet block explorer; encrypted messaging; live statistics and market data; in-wallet mining worker statistics and mining calculator; dashboard news; multi-currency conversion data (Bitcoin and 21 other currencies supported); the ability to export transactions; one-click wallet updates with automatic notification; automatic 24-hour wallet backups. Original announcement.
97. Zetacoin (ZET) (97)
Zetacoin (ZET) is a decentralised open-source cryptocurrency forked from Bitcoin in 2013. Zetacoin is similar to Bitcoin, but it uses newer technologies to improve the transfer speed; zetacoins are usually received within 30 seconds, making them ideal for swift, smaller, day-to-day transactions. The second important difference is that Zetacoin is inflationary. The initial supply of 160 million zetacoins are supplemented with a further 1 million coins per year, making up for lost coins and sustaining the increasing demand for the coin. Zetacoin was not pre-mined at launch and is therefore considered as a "fair-mined" cryptocurrency. Original announcement.
98. OKCash (OK) (98)
OKCash (OK) is a decentralised, open-source cryptocurrency forked from BlackCoin in November 2014 (originally as PimpCash before its rebranding to OKCash in April 2015). It is a pure proof-of-stake coin which pays a variable interest rate - it started with 69%, but this was reduced to 20% after the first year which will be followed by 10 more "halvings" in the coming years. Original announcement.
99. CasinoCoin (CSC) (99)
CasinoCoin (CSC) is a decentralised, open-source cryptocurrency forked in July 2013 from Litecoin, although it also imported some features from Bitcoin, Feathercoin and Digitalcoin. It is designed specifically for the online casino gaming. It was launched as a response to increasing difficulties to deposit funds for online casino gaming due to deposit restrictions between centralised financial institutions and online casino platforms. The total coin supply is set to 336 million none of which were pre-mined. Original announcement.
100. Crypto Bullion (CBX) (100)
Crypto Bullion (CBX), formerly known as Cryptogenic Bullion, is a decentralised, open-source cryptocurrency forked from Novacoin in June 2013. During the first few years it was a hybrid proof-of-work/proof-of-stake currency which allowed coin generation by both mining (using the scrypt hashing algorithm) and staking (at 1.5% annual interest), but with the release of version 2.0 in December 2015 Crypto Bullion became a pure proof-of-stake coin (at an annual interest of 2%). It has a block interval of 65 seconds and a difficulty-retarget every 2 blocks. Crypto Bullion's goal is to become a universally-accepted digital asset with all of the properties of gold - portable, divisible, fungible, scarce, durable, non-consumable, and a store of wealth. Original announcement.
101. Nxt (NXT) (101)
Nxt (NXT) is an open-source cryptocurrency and payment network launched in November 2013 by anonymous software developer BCNext. Created from scratch and written in Java, it uses proof-of-stake, a method of achieving distributed consensus and securing a cryptocurrency network, to provide consensus for transactions. As such, there is a static money supply and no mining. Nxt is specifically conceived as a flexible platform to build applications and financial services around. It has an integrated asset exchange (comparable to shares), messaging system and marketplace. Future releases will also allow users the creation of new currencies within the system. Original announcement.
102. Novacoin (NVC) (103)
Novacoin (NVC) is a decentralised open-source cryptocurrency forked from Peercoin in February 2013. Like its parent, it uses a hybrid proof-of-work / proof-of-stake consensus protocol, with scrypt as its preferred hashing algorithm. Novacoin has no hard cap limit except for the 2 billion maximum that has been entered for coding purposes; this can be lifted in the future if needed. Original announcement (in Russian).
103. Opal (OPAL) (104)
Opal (OPAL) is a decentralised, open-source cryptocurrency released in September 2014 as a re-branded OnyxCoin. The project's main focus is on developing what it calls "Opacity technologies", which implement several unique features in the cryptocoin's blockchain. These include encrypted messaging (messages can be encrypted, stored and sent anonymously to contacts), opaque addresses (mathematical functions to protect personal financial transactions and keep them hidden from public view), and in-wallet trading using the Bittrex exchange. All these features are available directly in Opal's custom-built wallet. Original announcement.
104. Capricoin (CPC) (105)
Capricoin (CPC) is a decentralised, open-source cryptocurrency forked from Novacoin in July 2015. It is a pure proof-of-stake (PoS) coin, paying a diminishing interest rate that started at 2% per annum. Of the projected supply of 208 million coins, 200 million were pre-mined; about half of that amount was designating for future distribution to users maintaining the network and staking the coins. Capricoin is a reasonably fast coin, providing transaction confirmation times of just 60 seconds. Original announcement.
105. Fluttercoin (FLT) (106)
Fluttercoin (FLT) is a decentralised, open-source cryptocurrency launched in March 2014. Although it uses a hybrid Proof-of-Work/Proof-of-Stake consensus mechanism, the project has introduced a new mining rewards system named Proof-of-Transaction (FLT coins are mined simply by receiving or sending them) which should act as an economic stimulus designed to gain merchants' acceptance and make the coin circulate in the digital economy. Some of the more interesting features incorporated in the custom Fluttercoin wallet include Flutterspeed (speeds up the download of the blockchain on new installations), Fluttershare (ability to share stake rewards with another address), Block Browser (to browse the blockchain from within the wallet) and encrypted messaging. Original announcement.
106. Rimbit (RBT) (107)
Rimbit (RBT) is a decentralised cryptocurrency launched in May 2014 as a fork of Novacoin. It is a pure proof-of-stake coin which is not generated by mining.
107. UnbreakableCoin (UNB) (108)
UnbreakableCoin (UNB) is a decentralised, open-source cryptocurrency forked from Bitcoin in March 2014. Original announcement.
108. Sterlingcoin (SLG) (109)
Sterlingcoin (SLG) is a decentralised, open-source cryptocurrency forked from Bitcoin in 2014. The project's primary goal is to provide an energy-efficient cryptocurrency, using technologies and innovations from PeerCoin and Novacoin, such as the proof-of-stake consensus mechanism. It uses the X13 hashing algorithm for increased resistance to coin mining with specialist hardware. Original announcement.
109. Counterparty (XCP) (110)
Counterparty (XCP) is a decentralised financial platform and distributed, open-source Internet protocol built on top of the Bitcoin blockchain and network. Counterparty provides users with a functioning decentralized digital currency exchange, as well as the ability to create virtual assets, issue dividends, create price feeds, bets and contracts. Counterparty also has a native currency that trades on cryptocurrency exchanges as XCP. XCP is not mined; instead, it was issued using a provable method called "proof of burn" which involves sending bitcoins to a special address that renders them permanently unspendable. Original announcement.
110. CryptoEscudo (CESC) (111)
CryptoEscudo (CESC) is a decentralised open-source cryptocurrency forked from Litecoin in March 2014. As the names suggests, it is intended as a national cryptocurrency of Portugal, borrowing the name of the old Portuguese currency before the country's adoption of the euro. CryptoEscudo differs from Litecoin in that its difficulty adjustment mechanism is based on Kimoto's Gravity Well where mining difficulty is adjusted after every single completed block of transactions. The cryptocurrency's total coin supply is capped at one billion units of which 45% were pre-mined. One half of the pre-mined coins is intended for an airdrop to the citizens of Portugal, while the other half is safeguarded for a future repayment of Portugal's national debt. Original announcement.
111. Freicoin (FRC) (112)
Freicoin (FRC) is an open-source, decentralised cryptocurrency launched in December 2012 as a fork of Bitcoin. Compared to the parent, it comes with an interesting economic ideology as well as a concept of "demurrage". The cryptocurrency imposes a negative 5% interest rate called demurrage fee (distributed to the miners) which is designed to encourage users of Freicoin to deploy the money for its original purpose - as a means of exchange, rather than as a store of value. On the technical side, Freicoin is a proof-of-work cryptocurrency that uses the SHA-256 hashing algorithm for mining the coins. The design of Freicoin specifies that during the initial money creation period (approximately three years), 80% of the generated Freicoins are to be distributed by the Freicoin Foundation via donations and only 20% are awarded to the miners. The total coins supply is set to 100 million freicoins. Original announcement.
112. Infinitecoin (IFC) (113)
Infinitecoin is an open-source peer-to-peer cryptocurrency forked from Litecoin in 2013. Some of its features include high circulation volume (at 90.6 billion coins), fast transaction times, an advanced check-pointing system that limits the effect of 51% attacks, and a wallet message system that warns users to postpone transactions if security issues are discovered. Original announcement.
113. I/O Digital Currency (IOC) (114)
I/O Digital Currency (IOC) is a decentralised cryptocurrency forked from Novacoin in July 2014. It is a pure proof-of-stake cryptocurrency, except for the initial 14-day proof-of-work period that generated a total of 16 million coins by mining - using the X11 array of hashing algorithms. There was no pre-mine. The proof-of-stake stage carries a 2% percent interest rate on staked coins and the total coin supply is set to 22 million. IOCoin comes with an interesting innovation called IONS (I/O Name Server), a feature that allows sending and receiving payments by using a registered user name. Besides a standard Qt-based wallet, the project developers also provide a more modern alternative based on HTML5. Original announcement.
114. MonetaryUnit (MUE) (115)
MonetaryUnit (MUE) is a decentralised open-source cryptocurrency forked from Quark in July 2014. The project's main feature is a special 8-way random hashing algorithm which is designed to preserve the coin's ability to be mined with standard home computers, rather than highly specialist ASIC systems. The coin supply is capped at a rather massive one quadrillion, although with its decreasing inflation target it will take centuries to reach that level. Around 78 million of MonetaryUnit coins were mined before the end of January 2015 and this number is projected to grow to around 1.15 billion by early 2049. The cryptocurrency's client is a standard Qt5-based wallet with several useful additions, including a blockchain explorer, mining and market information pages, and a blockchain-based chat room. Original announcement.
115. Netcoin (NET) (116)
Netcoin (NET) is a decentralised, open-source cryptocurrency forked from Litecoin and Peercoin in September 2013. Originally it was a pure proof-of-work currency with scrypt as its hashing algorithm, but later the project added a custom proof-of-stake mechanism which it called Personal Investment Rate (PIR). This was meant to increase Netcoin's adoption and savings rate as "stakers" were awarded NET coins based on the number of coins already present in their wallets. As a further incentive to keep the network healthy, Netcoin has implemented what it calls Open Wallet Incentive (OWI), a declining rate of reward for those wallet users who do not stake. Original announcement.
116. NobleCoin (NOBL) (117)
NobleCoin (NOBL) is a decentralised, open-source cryptocurrency forked from Florincoin in January 2014, but it was later re-based on Peercoin's source code. Registered as a business entity in Australia, the project's focus is on transparency, philanthropy and digital currency education as it attempts to become the forefront of international philanthropic efforts using cryptocurrencies for direct donations at near zero costs. Technically, NobleCoin is a pure proof-of-stake (PoS) cryptocurrency with the annual stakers' interest rate set at 8%. Original announcement.
117. BitCrystals (BCY) (118)
BitCrystals (BCY) are digital assets acting as both the game-fuel and the premium in-game currency in EverdreamSoft's Spells of Genesis game. BitCrystals were issued in February 2015 in a limited supply of 100 million units, 70% of which were offered for purchase during the initial BitCrystals crowdsale. BitCrystals can be traded on the Counterparty blockchain or used to purchase blockchain-based cards, playable within Moonga and Spells of Genesis. As an asset issued on the Counterparty (XCP) platform, the project does not provide an independent wallet, although a client is available from Google's Chrome Web Store as an extension for the Chrome and Chromium web browsers. Original announcement.
118. Digitalcoin (DGC) (119)
Digitalcoin (DGC) is a decentralised open-source cryptocurrency forked from Bitcoin in 2013. Developed by Digitalcoin Foundation, the software makes use of multi-algorithm hashing (scrypt, SHA-256 and x11) for increased transaction security. Original announcement.
119. RubyCoin (RBY) (120)
RubyCoin (RBY) is a decentralised open-source cryptocurrency launched in February 2014. Initially, it appeared to be a fork if Litecoin, with a proof-of-work consensus mechanism, scrypt hashing algorithm, a total supply of 60 million coins, and a modest 2% premine. Starting with the November 2014 release of RubyCoin's wallet version 2.0, the cryptocurrency has switched to a pure proof-of-stake consensus mechanism, paying a flat 5% interest on staked coins to support the network. Its desktop client is a Qt5-based application with a custom ruby-coloured theme. Original announcement.
120. TrollCoin (TROLL) (121)
TrollCoin (TROLL) [formerly TrollCoin (TRL)] is a decentralised, open-source cryptocurrency launched in February 2014 as a fork of Novacoin. It is a hybrid proof-of-work/proof-of-stake (PoW/PoS) coin, using the scrypt algorithm for PoW mining and a static PoS reward of 7 TROLL. Originally TrollCoin's total coin supply was set at 9 billion, but with the release of version 2.0 (in early December 2015), the cryptocurrency was relaunched with a new blockchain and updated parameters. The total coin supply was reduced to 900 million, the proof-of-stake period limited to 7,777,777 blocks, and a proof-of-stake reward system was introduced for the first time. Original announcement.
121. SolarCoin (SLR) (122)
SolarCoin (SLR) is a decentralised and open-source cryptocurrency forked from Litecoin in early 2014. It is backed by two forms of proof of work; one is the traditional cryptographic proof of work associated with a digital currency, while the other is Solar Renewable Energy Certificate (SREC) that has been generated and independently verified by a third party. SolarCoin is equitably distributed using both of these proofs of work as a means to reward renewable energy production. The intent is to provide an incentive to produce more solar electricity by rewarding the generators of solar electricity. In September 2015 the coin has become a pure proof-of-stake cryptocurrency paying an annual interest rate of 2%. Original announcement.
122. StartCOIN (START) (123)
StartCOIN (START) is a decentralised, open-source cryptocurrency forked from Litecoin in June 2014. It was conceived as the first cryptocurrency to support crowdfunding (through the StartJOIN.com platform), a way for start-up companies to raise funds in the Internet era. Technically, StartCOIN is a proof-of-work coin that uses the X11 array of hashing algorithms, DigiShield as the difficulty retargeting mechanism, and fast 1-minute transaction confirmation time. The total coin supply is 84 million startcoins, half of which were pre-mined; these are continuously being donated to new start-ups and active StartJOIN users. Original announcement.
123. FastCoin (FST) (124)
FastCoin (FST) is a decentralised open-source cryptocurrency forked from Litecoin in May 2013. Like its parent, FastCoin is a proof-of-work coin that uses scrypt as its hashing algorithm. However, it differs from Litecoin in that it deploys a custom difficulty adjustment mechanism to prevent "instamining", a process of rapid coin generation by insiders and very early adopters. It was launched with a zero pre-mine. FastCoin features a block generation target rate of 12 seconds with just 4 confirmations required, making it one of the fastest cryptocurrencies on the market in terms of block confirmation times (48 seconds). Original announcement.
124. FIMKrypto (FIMK) (125)
FIMKrypto (FIMK) is an open-source cryptocurrency and payment network forked from (and compatible with) Nxt (NXT) in July 2014. It is intended as a national cryptocurrency of Finland, with a goal of offering all Finnish citizens a regular basic income. Besides being a modern cryptocurrency platform, FIMKrypto also provides numerous useful decentralised functions, such as direct transmissions of payments from person to person, strongly encrypted private messaging, and other features. As with most cryptocurrencies, nodes running the FIMK wallet software are eligible to compete for block rewards that are distributed automatically every 30 seconds. Original announcement.
125. Megacoin (MEC) (126)
Megacoin (MEC) is a decentralised and open-source cryptocurrency forked from Bitcoin in 2013. Megacoin's total coin cap is limited to 42 million, with the number 42 derived from Hitchhiker's Guide to the Galaxy which identifies 42 as the "answer to the ultimate question of life, the universe and everything". The second interesting characteristic of Megacoin is the use of "Kimoto's Gravity Well" (a conceptual model of the gravitational field surrounding a body in space) as the mining difficulty re-adjustment algorithm. Original announcement.
126. SaffronCoin (SFR) (127)
SaffronCoin (SFR) is a decentralised, open-source cryptocurrency forked from Bitcoin in April 2014. The project improves on the original in that it enables its proof-of-work mining process using five different hashing algorithms (the default SHA-256, along with BLAKE, Grøstl, scrypt and X11), thus making it more difficult for large crypto-mining farms to monopolise the coin-generation process. SaffronCoin's second most interesting feature is its multi-tasking wallet client. Developed using the WebKit web browser engine, the wallet provides not only standard payment features, but also standard web content, a tweet box, data feeds from cryptocurrency exchanges, built-in IRC chat, and a number of other innovative features. Original announcement.
127. HoboNickels (HBN) (129)
HoboNickels (HBN) is a decentralised cryptocurrency launched in September 2013 as a fork of Novacoin. It started as a hybrid proof-of-work/proof-of-stake (PoW/PoS) coin, but the PoW part was later phased out. The software offers a generous interest on staked coins ranging from 20% to 100% annually. Original announcement.
128. PopularCoin (POP) (130)
PopularCoin (POP) is a decentralised open-source cryptocurrency forked from Litecoin in January 2014. It started as a proof-of-work cryptocurrency with a total supply of 4.9 billion coins and no premine, but the coin will eventually become a hybrid proof-of-work/proof-of-stake cryptocurrency, with the proof-of-stake part being called "proof of participation". This feature gives users an extra incentive to run the PopularCoin client as it generates free coins by allowing the participant to cast a vote on supplied polls for popular media in the entertainment sector. Original announcement.
129. YBCoin (YBC) (131)
YBCoin (YBC), sometimes spelt as Ybcoin, is a decentralised, open-source cryptocurrency launched in China in June 2013 as a fork of YACoin which itself was a fork of Novacoin. It is a pure proof-of-stake coin providing an annual interest of 1% on staked coins. It is a popular coin in China where it has reached substantial trading volumes and high market capitalisation. However, it is not traded on any of the main altcoin exchanges outside its country of origin. Original announcement.
130. Steps (STEPS) (132)
Steps (STEPS) is a decentralised open-source cryptocurrency launched in September 2015 as a fork of Novacoin. It is a pure proof-of-stake (PoS) coin which pays a variable interest rate depending on the amount of "staked" coins; starting from block 60,100 the PoS interest will be set to 1%. The project's future plans include various additional services, such cryptocurrency trading platform, payment gateway and web wallet. Original announcement.
131. Storj (Not ranked)
Storj is a project that uses the blockchain technology to provide decentralised cloud storage shared by users running the Storj software. Storj (STORJ), formerly Storjcoin X (SCJX) and released in July 2014, is an open-source cryptocurrency that supports the Storj network and is offered as a reward to those users who choose to provide storage space on their computers using the project's easy-to-configure Storj Share application. A separate software program, MetaDisk, is available to those who want to store files on the Storj cloud network. While Storjcoin X can be traded on major altcoin exchanges, it is not an independent cryptocurrency; it is issued on top of the Counterparty (XCP) protocol instead. The total supply of SJCX coins is limited to 500 million. Original announcement.
