The following cryptocoins match your criteria (sorted by popularity):
1. Monero (XMR) (1)
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.
2. Bitcoin (BTC) (2)
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.
3. Factom (FCT) (3)
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.
4. Shadow (SDC) (4)
5. Zcash (ZEC) (5)
6. Gulden (NLG) (6)
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.
7. Decred (DCR) (7)
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.
8. Bytecoin (BCN) (9)
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.
9. Ethereum (ETH) (10)
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.
10. Stellar Lumen (XLM) (11)
11. BitShares (BTS) (12)
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 PhotoShares (PTS); it was later renamed to BitShares (PTS) and "reloaded" in November 2014 by merging several products into BitShares (BTS).
12. NEM (XEM) (13)
13. Dash (DASH) (14)
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.
14. NAV Coin (NAV) (15)
15. 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.
16. CLAMS (CLAM) (17)
Clams (CLAM) is a decentralised, open-source cryptocurrency forked from Novacoin 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.
17. Emercoin (EMC) (18)
EmerCoin (EMC) is a decentralised, open-source cryptocurrency created in late 2013 and based on technologies from Bitcoin, Namecoin and Peercoin. It is a hybrid proof-of-work/proof-of-stake (PoW/PoS) coin which uses the SHA-256 hashing algorithm to "mine" the coins and it also offers a 6% annual interest on staked coins. EmerCoin implements the RFC3489 (STUN) protocol that uses geographically distributed servers for external IP discovery. Another interesting feature of EmerCoin lies in its blockchain which provides a name-value storage system, including an integrated DNS server for *.coin, *.emc, *.lib, *.bazar domains. Original announcement.
18. BitcoinDark (BTCD) (19)
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.
19. Litecoin (LTC) (20)
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.
20. Steem (STEEM) (21)
21. CureCoin (CURE) (22)
CureCoin (CUR) is a decentralised, open-source cryptocurrency forked from Litecoin in November 2013. 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.
22. Lisk (LSK) (23)
23. Sia (SC) (24)
24. vTorrent (VTR) (25)
25. Burstcoin (BURST) (26)
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.
26. Counterparty (XCP) (27)
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.
27. Dogecoin (DOGE) (28)
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).
28. Bitmark (BTM) (29)
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.
29. Feathercoin (FTC) (30)
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.
30. NuBits (NBT) (31)
31. BlackCoin (BLK) (32)
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
32. Vcash (XVC) (33)
33. GoldCoin (GLD) (34)
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.
34. VeriCoin (VRC) (35)
35. Storjcoin X (SJCX) (36)
36. Syscoin (SYS) (37)
37. YoCoin (YOC) (38)
38. 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.
39. Europecoin (ERC) (40)
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.
40. Nxt (NXT) (41)
41. Unobtanium (UNO) (42)
42. Gridcoin (GRC) (43)
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.

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.
46. Ethereum Classic (ETC) (47)
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.

51. Anoncoin (ANC) (52)
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
52. Bata (BTA) (53)
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.
53. Capricoin (CPC) (54)
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.
54. DigiByte (DGB) (55)
DigiByte (DGB) is a decentralised, open-source cryptocurrency and payment network launched in January 2014 as a fork of Bitcoin.

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.
63. BitCrystals (BCY) (65)
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.
64. Blocknet (BLOCK) (66)
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.
65. Breakout Coin (BRK) (67)
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.
66. CannabisCoin (CANN) (68)
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.

69. Worldcoin (WDC) (71)
70. Deutsche eMark (DEM) (72)
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.
71. e-Gulden (EFL) (73)
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.
72. I/O Digital Currency (IOC) (74)
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.
73. MintCoin (MINT) (75)
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.
74. ziftrCOIN (ZRC) (76)
75. Crypto Bullion (CBX) (77)
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.
76. Digitalcoin (DGC) (78)
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.
77. Groestlcoin (GRS) (79)
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.

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.
86. Florincoin (FLO) (88)
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.
87. Monacoin (MONA) (89)
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.
88. NeuCoin (NEU) (90)
89. Paycoin (XPY) (91)
90. Primecoin (XPM) (92)
91. Quark (QRK) (93)
92. Blakecoin (BLC) (94)
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.
93. EarthCoin (EAC) (95)
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.
94. Fluttercoin (FLT) (96)
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.
95. MazaCoin (MZC) (97)
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.
96. MonetaryUnit (MUE) (98)
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.
97. SaffronCoin (SFR) (99)

100. DNotes (NOTE) (103)
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.
101. GoldBlocks (GB) (104)
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.
102. CloakCoin (CLOAK) (105)
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.
103. Megacoin (MEC) (106)
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.
104. NobleCoin (NOBL) (107)
105. BitSwift (SWIFT) (108)
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%.

Original announcement.
107. FastCoin (FST) (110)
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.
108. Freicoin (FRC) (111)
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.
109. Zeitcoin (ZEIT) (112)
110. CasinoCoin (CSC) (113)
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.
111. CryptoEscudo (CESC) (114)
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.
112. FIMKrypto (FIMK) (115)
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.
113. Infinitecoin (IFC) (116)
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.
114. Krypton (KR) (117)
Krypton (KR) is a decentralised, open-source cryptocurrency launched in February 2016. It started life as an Ethereum "sidechain", but following a devastating 51% attack in September 2016, the project abandoned the Ethereum base and forked to become an independent proof-of-work cryptocurrency at first, moving to proof-of-stake blockchain September 2016. Krypton, USA-based startup founded by Stephanie Kent, aims provide an easy way to register decentralised autonomous organisations (DAO), create smart contracts and build distributed applications. Compared to Ethereum, it offers fewer initial coins (2.69 million), faster block speed (15 seconds) and lower inflation. Original announcement.
