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. 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.
3. Litecoin (LTC) (12)
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.
4. Primecoin (XPM) (23)
Primecoin (XPM) is an open-source peer-to-peer cryptocurrency that implements a unique proof-of-work system based on scientific computing and prime numbers. Besides providing security and minting to the network, Primecoin also generates a special form of prime number chains (known as Cunningham chains and bi-twin chains) which are currently not well-understood and which could be of interest to mathematical research. Original announcement.
5. Omni (OMNI) (28)
Omni (OMNI) is an open-source, decentralised cryptocurrency and communications protocol built on top of the Bitcoin blockchain. Launched in January 2015, Omni is a logical continuation of Mastercoin (MSC), a simple cryptocurrency which had been created in July 2013 as a fork of Bitcoin. Unlike Mastercoin, Omni Layer is a highly ambitious effort that seeks to take advantage of Bitcoin's blockchain to build support for additional distributed services, such as a decentralised currency exchange, digital assets trading and smart contracts. Although Mastercoin (MSC) is still traded on some exchanges, the current series of desktop wallet clients provide support for Bitcoin (BTC) and Omni (OMNI) only, while the project's web-based client (called Omniwallet) can be customised to include other assets.
6. Bitcoin Cash (BCH) (39)
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.
7. Decred (DCR) (40)
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. 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.
9. Syscoin (SYS) (46)
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.
10. Anoncoin (ANC) (49)
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
11. NavCoin (NAV) (50)
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.
12. Bitcoin Gold (BTG) (53)
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.
13. CloakCoin (CLOAK) (57)
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.
14. Namecoin (NMC) (60)
Namecoin (NMC) is a decentralized open-source cryptocurrency forked from Bitcoin in 2011. It uses the same proof-of-work algorithm and is limited to 21 million coins, but it offers several innovation, such as the ability to store data within its blockchain or merged mining. Namecoin's flagship use-case is the censorship resistant top level domain .bit, which is functionally similar to .com domains but independent of ICANN, the main governing body for domain names. In early 2014 the project released FreeSpeechMe, a Firefox plug-in that allows automatical resolution of .bit addresses. Original announcement.
15. Peercoin (PPC) (63)
Peercoin (PPC) is a decentralised open-source cryptocurrency forked from Bitcoin in 2012. Peercoin's major distinguishing feature, compared to Bitcoin and most other cryptocurrencies, is that it uses a hybrid proof-of-stake/proof-of-work system as its consensus mechanism, thus reducing the risk of certain network vulnerabilities. Other characteristics include increased energy efficiency during the mining process, no hard limit on the total number of coins issued, a 1% annual inflation, and fixed protocol-defined transaction (at 0.01 PPC) fees which are destroyed to offset the inflation rate and to self-regulate transaction "spam" by eliminating low-value payments. Original announcement.
16. LeafCoin (LEAF) (67)
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.
17. Europecoin (ERC) (73)
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.
18. EverGreenCoin (EGC) (79)
EverGreenCoin (EGC) is a decentralised, open-source cryptocurrency forked from Bitcoin and inaugurated in December 2015. It started life as a proof-of-work (PoW) coin using the X15 spectrum of hashing algorithms for generating coins, but it was converted into a pure proof-of-stake (PoS) currency some six month after its launch. It offers a 7% annual interest on staked coins. EverGreenCoin's parameters make it a faster and more environmentally-friendly cryptocurrency than Bitcoin. Initial announcement.
19. Groestlcoin (GRS) (80)
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.
20. Neos (NEOS) (81)
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.
21. Quark (QRK) (84)
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.
22. Blakecoin (BLC) (92)
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.
23. Breakout Coin (BRK) (93)
Breakout Coin (BRK) is a product of Breakout Gaming which is a new, globally accessible online gaming entertainment company that plans to provide poker, sports wagering, casino games, fantasy sports, and other popular gaming options. The original currency, Breakout Coin, was later integrated into a unique multi-currency wallet system called "Breakout Chain". While Breakout Coin (BRK) remains the principal currency for Breakout Gaming, there are also Breakout Stake (BRX) and Sister Coin (SIS) which serve to secure the ledger through a combined proof-of-stake (PoS) and proof-of-work (PoW) model. The PoS system uses Breakout Stake as the stake, minting Breakout Coin. As such, the Breakout Stake money supply will never increase, whereas the Breakout Coin money supply increases at a rate of approximately 5% per year. Breakout Chain’s PoW system produces Sister Coin as an incentive to miners. Original announcement.
24. Digitalcoin (DGC) (112)
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.
25. 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.
26. Sterlingcoin (SLG) (122)
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.
27. Freicoin (FRC) (125)
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.
28. Opal (OPAL) (127)
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.
29. 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.
