1. Omni (OMNI) (24)
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.
2. Diamond (DMD) (27)
Diamond (DMD) is a decentralised, open-source cryptocurrency launched in July 2014. As a hybrid proof-of-work/proof-of-stake coin, it combines various interesting aspects of other popular cryptocurrency projects, including Bitcoin, Litecoin, Novacoin, Luckycoin (random block feature) and Florincoin (support for transaction comments). Other features include very low transaction fees, steady coin supply at one diamond per block for eight years, and a limited number of total coins capped at just 4.38 million. Original announcement.
3. Dogecoin (DOGE) (36)
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).
4. Earthcoin (EAC) (43)
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.
5. Emercoin (EMC) (44)
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.
6. GoldCoin (GLD) (45)
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.
7. Deutsche eMark (DEM) (53)
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.
8. Anoncoin (ANC) (60)
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
9. Unobtanium (UNO) (63)
Unobtanium (UNO) is a decentralised open-source cryptocurrency forked from Bitcoin in 2013. It derives its name from a fictional engineering and scientific term that describes an extremely rare or impossible-to-obtain element. Members of the UNO community often measure the amount of their UNO cryptocurrency holdings in kilograms rather than coins. Unobtanium is a rare, SHA-256 proof-of-work cryptocurrency with the maximum supply of just 250,000 coins. With 0% pre-mining and no replacements for lost unobtaniums, it is considered a "fair-mined" cryptocurrency, with scarcity being its most distinguished feature. Original announcement.
10. Nxt (NXT) (65)
Nxt (NXT) is an open-source cryptocurrency and payment network launched in November 2013 by anonymous software developer BCNext. Created from scratch and written in Java, it uses proof-of-stake, a method of achieving distributed consensus and securing a cryptocurrency network, to provide consensus for transactions. As such, there is a static money supply and no mining. Nxt is specifically conceived as a flexible platform to build applications and financial services around. It has an integrated asset exchange (comparable to shares), messaging system and marketplace. Future releases will also allow users the creation of new currencies within the system. Original announcement.
11. Gridcoin (GRC) (66)
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.
12. Feathercoin (FTC) (69)
Feathercoin is an open-source digital currency forked from Litecoin in 2013. The project's main innovation is NeoScrypt, a processor-intensive hashing algorithm that makes it difficult to mine coins with specialist hardware, such as ASIC. Another interesting feature of Feathercoin is the implementation of "advanced checkpointing" in its blockchain to guard against the "51% attack", a known vulnerability in the Bitcoin software. The developers of Feathercoin have been experimenting with additional software and hardware projects not found in most other cryptocurrencies, e.g. development of ATMs and Point-of-Sales equipment, T-shirt wallets, laser-etched physical coins and several Raspberry Pi-based projects. Original announcement.
13. Quark (QRK) (72)
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.
14. Blakecoin (BLC) (76)
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.
15. Florincoin (FLO) (77)
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.
16. Netcoin (NET) (80)
Netcoin (NET) is a decentralised, open-source cryptocurrency forked from Litecoin and Peercoin in September 2013. Originally it was a pure proof-of-work currency with scrypt as its hashing algorithm, but later the project added a custom proof-of-stake mechanism which it called Personal Investment Rate (PIR). This was meant to increase Netcoin's adoption and savings rate as "stakers" were awarded NET coins based on the number of coins already present in their wallets. As a further incentive to keep the network healthy, Netcoin has implemented what it calls Open Wallet Incentive (OWI), a declining rate of reward for those wallet users who do not stake. Original announcement.
17. Zetacoin (ZET) (82)
Zetacoin (ZET) is a decentralised open-source cryptocurrency forked from Bitcoin in 2013. Zetacoin is similar to Bitcoin, but it uses newer technologies to improve the transfer speed; zetacoins are usually received within 30 seconds, making them ideal for swift, smaller, day-to-day transactions. The second important difference is that Zetacoin is inflationary. The initial supply of 160 million zetacoins are supplemented with a further 1 million coins per year, making up for lost coins and sustaining the increasing demand for the coin. Zetacoin was not pre-mined at launch and is therefore considered as a "fair-mined" cryptocurrency. Original announcement.
18. Primecoin (XPM) (84)
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.
19. Infinitecoin (IFC) (87)
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.
20. Worldcoin (WDC) (91)
Worldcoin (WDC) is a decentralised open-source digital currency secured by cryptography. Forked from Bitcoin in 2013, the project's primary goal is to create a business-friendly payment system that would become the choice for merchants and consumers for everyday transactions. Worldcoin prides itself for having very fast transaction speeds, fully confirmed in less than 60 seconds. The coin's creators hope to sponsor world-changing projects, starting with an installation of a Worldcoin community-sponsored clean water well in Kenya. Original announcement.
21. YBCoin (YBC) (93)
YBCoin (YBC), sometimes spelt as Ybcoin, is a decentralised, open-source cryptocurrency launched in China in June 2013 as a fork of YACoin which itself was a fork of Novacoin. It is a pure proof-of-stake coin providing an annual interest of 1% on staked coins. It is a popular coin in China where it has reached substantial trading volumes and high market capitalisation. However, it is not traded on any of the main altcoin exchanges outside its country of origin. Original announcement.
22. FastCoin (FST) (95)
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.
23. HoboNickels (HBN) (96)
HoboNickels (HBN) is a decentralised cryptocurrency launched in September 2013 as a fork of Novacoin. It is a hybrid proof-of-work/proof-of-stake coin. Original announcement.
24. Novacoin (NVC) (98)
Novacoin (NVC) is a decentralised open-source cryptocurrency forked from Peercoin in February 2013. Like its parent, it uses a hybrid proof-of-work / proof-of-stake consensus protocol, with scrypt as its preferred hashing algorithm. Novacoin has no hard cap limit except for the 2 billion maximum that has been entered for coding purposes; this can be lifted in the future if needed. Original announcement (in Russian).
25. Crypto Bullion (CBX) (99)
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.
26. Digitalcoin (DGC) (101)
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.
27. CasinoCoin (CSC) (120)
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.
28. Megacoin (MEC) (121)
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.
29. Orbitcoin (ORB) (123)
Orbitcoin (ORB) is a decentralised, open-source cryptocurrency launched in July 2013 as a fork of Novacoin. It is a hybrid proof-of-work/proof-of-stake coin with a total coin supply of just 3.77 million units. As such, orbitcoins can be both mined (using the NeoScrypt hashing algorithm) and minted (SHA-256) - both methods carry a fixed reward of 1 ORB. Other features of the cryptocurrency include: one-minute combined block target, time warp and "instamining" protection, advanced checkpointing against 51% attacks, and very low transaction fees. Original announcement.
