The following cryptocoins match your criteria (sorted by popularity):
1. BitShares (BTS) (4)
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).
2. Monero (XMR) (5)
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.
3. Bitmark (BTM) (6)
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.
4. CLAMS (CLAM) (7)
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.
5. AEON (AEON) (9)
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.
6. Reddcoin (RDD) (11)
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.
7. BlackCoin (BLK) (12)
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
8. Stellar Lumen (XLM) (19)
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.
9. CannabisCoin (CANN) (20)
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.
10. Monacoin (MONA) (21)
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.
11. Gulden (NLG) (26)
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.
12. Boolberry (BBR) (28)
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.
13. Auroracoin (AUR) (38)
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.
14. MintCoin (MINT) (40)
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.
15. PotCoin (POT) (42)
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.
16. Dash (DASH) (47)
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.
17. NavCoin (NAV) (48)
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.
18. Coin Magi (XMG) (50)
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.
19. Curecoin (CURE) (51)
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.
20. BitcoinDark (BTCD) (55)
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.
21. DigiByte (DGB) (56)
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. CloakCoin (CLOAK) (59)
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.
23. DigitalNote (XDN) (60)
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.
24. LeafCoin (LEAF) (61)
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.
25. Myriad (XMY) (62)
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.
26. NobleCoin (NOBL) (63)
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.
27. Syscoin (SYS) (64)
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.
28. Blocknet (BLOCK) (68)
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.
29. StealthCoin (XST) (75)
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.
30. 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.
31. Carboncoin (CARBON) (83)
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.

Original announcement.
32. Groestlcoin (GRS) (85)
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.
33. MazaCoin (MZC) (86)
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.
34. Neos (NEOS) (87)
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.

The BitSwift cryptocurrency and its blockchain run on the BlockNet platform. Original announcement.
39. NuBits (NBT) (97)
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.
40. MonetaryUnit (MUE) (100)
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.
41. Counterparty (XCP) (102)
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.
42. OKCash (OK) (106)
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.
43. 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.

Original announcement.
45. Fluttercoin (FLT) (112)
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.
46. StartCOIN (START) (115)
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.
47. CryptoEscudo (CESC) (117)
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.
48. I/O Digital Currency (IOC) (120)
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.
49. Opal (OPAL) (121)
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.
50. RubyCoin (RBY) (122)
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.
51. SolarCoin (SLR) (123)
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.
52. Sterlingcoin (SLG) (124)
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.
53. PopularCoin (POP) (127)
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.
54. SaffronCoin (SFR) (128)
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.
55. 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.
