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. Dogecoin (DOGE) (2)
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).
3. VERGE (XVG) (4)
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.
4. Zcoin (XZC) (7)
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.
5. Bytecoin (BCN) (8)
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.
6. Monero (XMR) (11)
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.
7. Sia (SC) (12)
Sia is an open-source, decentralised storage platform where users contribute disk storage from their computers to form a decentralized network. This disk storage space is available for rent. The Sia software provides a Bitcoin-like blockchain with smart contracts and strong encryption which ensures secure, reliable and private decentralised storage. As a payment medium the network uses Siacoin (SC), a proof-of-work (PoW) cryptocurrency, which can be generated by standard PoW mining (using the BLAKE hashing algorithm) or it can be purchased on a cryptocurrency exchange. Original announcement.
8. AEON (AEON) (13)
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.
9. Boolberry (BBR) (15)
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.
10. Gulden (NLG) (16)
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.
11. Zcash (ZEC) (19)
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.
12. Bitmark (BTM) (20)
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". The developers focus on implementing features that would make the software easy to use, yet free of unnecessary bloat. Some of the coin's technical parameters include: block time of 120 seconds; block maturity and difficulty re-target of 720 blocks (1 day); block reward of 20 BTM; total supply of about 27.58 million of coins with supply halving every 3 years and with intermediary decreases every 18 months. Original announcement.
13. CannabisCoin (CANN) (21)
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.
14. Litecoin (LTC) (22)
Litecoin is an open-source, peer-to-peer Internet currency forked from Bitcoin in 2011. Like Bitcoin, it enables instant, near-zero cost payments to anyone in the world. Litecoin's decentralised network is secured by complex mathematical computation which allows individuals to control their own finances. Compared to Bitcoin, Litecoin features faster transaction confirmation times and improved storage efficiency. It has emerged as the second most popular cryptocurrency, after Bitcoin. Original announcement.
15. Monacoin (MONA) (23)
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.
16. Steem (STEEM) (24)
Steem (STEEM) is an open-source, decentralised cryptocurrency created to reward posters on Steemit.com, the blockchain-based social media network. It is a proof-of-work coin available for mining by individual users via the project's software application written in Python. The initial code was experimental, with a unique consensus algorithm that discourages mining by large mining pools. Steemit, whose chief technology officer is BitShares founder Daniel Larimer, promises a fast-paced development, including a user-friendly graphical wallet client. Original announcement.
17. Syscoin (SYS) (29)
Syscoin (SYS) is an open-source peer-to-peer cryptocurrency. It attempts to extend Bitcoin's blockchain to provide not only digital money, but also to build a marketplace or a brokerage, and to enable the issuance and exchange of digital certificates. In essence, the project uses the blockchain's cryptographic features to build applications that will solve real-world problems or deliver useful solutions, e.g. verify wills, create trusts or build community trading platforms. Syscoin was launched in April 2004 with an 8% pre-mine, part of which was offered to early investors. Original announcement.
18. DigitalNote (XDN) (30)
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.
19. Diamond (DMD) (36)
Diamond (DMD) is a decentralised, open-source cryptocurrency launched in July 2014. As a hybrid proof-of-work/proof-of-stake coin, it combines various interesting aspects of other popular cryptocurrency projects, including Bitcoin, Litecoin, Novacoin, Luckycoin (random block feature) and Florincoin (support for transaction comments). Other features include very low transaction fees, steady coin supply at one diamond per block for eight years, and a limited number of total coins capped at just 4.38 million. Original announcement.
20. GoldCoin (GLD) (39)
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.
21. DigiByte (DGB) (41)
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. Auroracoin (AUR) (42)
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.
23. Komodo (KMD) (43)
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.
24. PotCoin (POT) (47)
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.
25. Zclassic (ZCL) (48)
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.
26. Dash (DASH) (50)
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.
27. DNotes (NOTE) (51)
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.
28. YoCoin (YOC) (54)
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.
29. Coin Magi (XMG) (56)
Coin Magi (XMG) is a decentralised, open-source cryptocurrency forked from Peercoin in September 2014. It is a hybrid proof-of-work/proof-of-stake cryptocurrency that allows coin generation by both mining and staking. Its mining method uses a unique M7M hashing algorithm, along with a particularly designed block rewarding system. As such, mining can only be accomplished using standard CPUs, allowing anybody with modest hardware to participate in the coin generation process, while disallowing large mining farms from taking part in mining. Original announcement.
30. LeafCoin (LEAF) (57)
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.
31. Anoncoin (ANC) (58)
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
32. Bitcoin Cash (BCH) (59)
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.
33. Worldcoin (WDC) (60)
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.
34. Myriad (XMY) (61)
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.
35. Viacoin (VIA) (62)
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.
36. Bitcoin Gold (BTG) (63)
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.
37. Europecoin (ERC) (64)
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.
38. Bata (BTA) (67)
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.
39. Feathercoin (FTC) (69)
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.
40. Neos (NEOS) (70)
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.
41. PascalCoin (PASC) (73)
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.
42. e-Gulden (EFL) (75)
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.
43. 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.
44. Unobtanium (UNO) (79)
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.
45. 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.
46. MazaCoin (MZC) (83)
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.
47. Quark (QRK) (86)
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.
48. Titcoin (TIT) (88)
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.
49. Blakecoin (BLC) (90)
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.
50. Carboncoin (CARBON) (93)
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.
51. Earthcoin (EAC) (94)
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.
52. Gridcoin (GRC) (96)
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.
53. Zetacoin (ZET) (102)
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.
54. CasinoCoin (CSC) (107)
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.
55. MonetaryUnit (MUE) (108)
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.
56. UnbreakableCoin (UNB) (110)
UnbreakableCoin (UNB) is a decentralised, open-source cryptocurrency forked from Bitcoin in March 2014. Original announcement.
57. CryptoEscudo (CESC) (112)
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.
58. Freicoin (FRC) (113)
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.
59. Counterparty (XCP) (115)
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.
60. Digitalcoin (DGC) (116)
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.
61. Megacoin (MEC) (118)
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.
62. StartCOIN (START) (119)
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.
63. Infinitecoin (IFC) (121)
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.
64. FastCoin (FST) (125)
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.
65. SaffronCoin (SFR) (129)
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.
