1. 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.
2. Shadow (SDC) (3)
Shadow (SDC), previously known as SDCoin and ShadowCoin, is a decentralised, open-source cryptocurrency forked from Blackcoin in July 2014. The project's primary focus is on transaction anonymity. Shadow features "ShadowSend", a zero-knowledge, dual-key stealth address and ring signature protocol that enables near-instant, untraceable, unlinkable and trustless transactions. Some of the project's other features include ShadowChat, a peer-to-peer, end-to-end encrypted messaging platform, and Cryptobrowser, an HTML-based wallet offering IP obfuscation and deep integration with the Tor network and the coin's other features. Shadow is a proof-of-stake cryptocurrency generating a 2% annual interest on staked coins. Original announcement.
3. 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.
4. Litecoin (LTC) (18)
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.
5. NEM (XEM) (20)
NEM (XEM), which stands for New Economy Movement, is a decentralised cryptocurrency launched in March 2015. Inspired by the Nxt project, it was written from scratch in Java. The most interesting features of the cryptocurrency include its proof-of-importance (POI) algorithm (with the level of importance determined by how many coins a wallet stores and the number of transactions made to and from the wallet), an integrated P2P-secure multi-signature account and encrypted messaging system, and an Eigentrust++ reputation system which evaluates the quality of each client's contribution to maintain the network. NEM uses a client–server model where the NIS (NEM Infrastructure Server) runs independent of the NCC (NEM Community Client); the client is designed to run locally, in a web browser. Original announcement.
6. Burstcoin (BURST) (27)
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.
7. 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).
8. NuBits (NBT) (29)
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.
9. 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.
10. 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.
11. Auroracoin (AUR) (44)
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.
12. Reddcoin (RDD) (47)
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.
13. Bata (BTA) (51)
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.
14. DigiByte (DGB) (55)
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.
15. ARCHcoin (ARCH) (61)
ARCHcoin (ARCH) is a decentralised, open-source cryptocurrency launched in October 2014 in Portugal. 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.
16. Myriad (XMY) (65)
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.
17. Peercoin (PPC) (67)
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.
18. CannabisCoin (CANN) (69)
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.
19. e-Gulden (EFL) (71)
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.
20. I/O Digital Currency (IOC) (72)
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.
21. MintCoin (MINT) (73)
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.
22. Digitalcoin (DGC) (80)
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.
23. Groestlcoin (GRS) (81)
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.
24. RubyCoin (RBY) (86)
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.
25. MazaCoin (MZC) (90)
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.
26. Fluttercoin (FLT) (97)
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.
27. Quark (QRK) (98)
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.
28. FastCoin (FST) (103)
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.
29. 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.
30. Infinitecoin (IFC) (113)
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.
31. MonetaryUnit (MUE) (115)
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.
32. Opal (OPAL) (116)
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.
33. Rimbit (RBT) (118)
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.
34. Sapience (XAI) (119)
