1. VERGE (XVG) (8)
Verge (XVG) (formerly DogecoinDark (DOGED)) is a decentralised, open-source cryptocurrency forked from Dogecoin in October 2014 and re-branded as VERGE in February 2016. The project exploited the growing popularity of the "fun" Dogecoin cryptocurrency while adding code to increase the coin's anonymity and privacy features, notably the network's ability to run on dedicated Tor nodes. Verge is a pure proof-of-work cryptocurrency that uses the scrypt hashing algorithm. The number of coins issued has been set to 9 billion during the first year and one billion per year thereafter. Original announcement.
2. Gulden (NLG) (13)
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.
3. DigiByte (DGB) (14)
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.
4. 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.
5. Reddcoin (RDD) (21)
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.
6. Dogecoin (DOGE) (23)
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).
7. BlackCoin (BLK) (26)
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. vTorrent (VTR) (27)
vTorrent (VTR) is an open-source, decentralised cryptocurrency launched in late 2014 as a fork of Shadow (SDC). The most distinctive (planned) feature of the software project was the incorporation of a BitTorrent client into the vTorrent wallet, thus trying to appeal to the many BitTorrent users while making the currency transactions more anonymous and difficult to trace. On a technical side, the coin was launched using the proof-of-work consensus mechanism and scrypt as the hashing algorithm to generate the initial pool of tokens (there was a 3% pre-mine), but was gradually moving to a proof-of-stake phase with a 5% interested rate payed to the "stakers". The vTorrent wallet is an advanced graphical software with some interesting features, such as anonymous chat, blockchain explorer and even an option to trade cryptocurrencies on the Bittrex exchange. Original announcement.
9. 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.
10. Omni (OMNI) (32)
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.
11. Monacoin (MONA) (38)
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.
12. Myriad (XMY) (39)
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.
13. NobleCoin (NOBL) (41)
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.
14. 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.
15. Gridcoin (GRC) (46)
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.
16. OKCash (OK) (52)
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.
17. Earthcoin (EAC) (53)
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.
18. Anoncoin (ANC) (55)
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
19. Bata (BTA) (56)
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.
20. Feathercoin (FTC) (57)
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.
21. Auroracoin (AUR) (58)
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.
22. PotCoin (POT) (62)
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.
23. Viacoin (VIA) (67)
Viacoin (VIA) is a decentralised, open-source cryptocurrency forked from Bitcoin in July 2014. The project's primary goal is to create a blockchain protocol, called "ClearingHouse", which would allow the building of fully decentralized exchanges and issuing of new currencies, as well as asset tracking, betting, digital voting, reputation management and going as far as allowing to form the basis of fully decentralized marketplaces. According to the project's management, these kind of services (or "sidechains") often face resistance from core Bitcoin developers when attempting to buil them on top of Bitcoin's own blockchain - hence the reason for launching the new cryptocoin. Viacoin's launch was accompanied by much attention in the media - especially because of the coin's explosive price growth (VIA reached market capitalisation of US$1 million in just a few days of trading), but also because the project was joined by Peter Todd, a well-known and experienced Bitcoin developer. Original announcement.
24. Florincoin (FLO) (69)
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.
25. Fluttercoin (FLT) (75)
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.
26. Novacoin (NVC) (76)
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).
27. Worldcoin (WDC) (78)
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.
28. ARCHcoin (ARCH) (83)
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.
29. Infinitecoin (IFC) (86)
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.
30. Netcoin (NET) (89)
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.
31. RubyCoin (RBY) (90)
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.
32. Digitalcoin (DGC) (91)
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.
33. e-Gulden (EFL) (94)
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.
34. YoCoin (YOC) (95)
YoCoin (YOC), also spelt as "Yocoin" or "YOcoin", is an open-source, decentralised cryptocurrency announced in December 2015 as a fork of Bitcoin. It is a proof-of-work coin which is generated by "mining", with scrypt as the hashing algorithm. The coin was launched publicly after a total of 15% of total supply was pre-mined; this was meant to be used only for giveaways, swap handling and YoCoin promotions. Original announcement.
35. DNotes (NOTE) (102)
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.
36. Orbitcoin (ORB) (103)
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.
37. SolarCoin (SLR) (104)
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.
38. Crypto Bullion (CBX) (105)
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.
39. FastCoin (FST) (106)
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.
40. Zeitcoin (ZEIT) (107)
Zeitcoin (ZEIT) is a decentralised open-source cryptocurrency launched in March 2014 as a fork of Peercoin. It began life as a hybrid proof-of-work/proof-of-stake coin that used the scrypt hashing algorithm for the initial generation of zeitcoins. Two months later the coin became a pure proof-of-stake (PoS) coin, initially paying an annual PoS interest of 25%, but this is expected to drop by 5% a year and eventually stay at 5% of annual PoS interest after year four. The coin features fast confirmation times of two minutes. A total of 1% of zeitcoins were pre-mined and allocated for bounties and software development. Original announcement.
41. Carboncoin (CARBON) (110)
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. The project's goal is to eliminate coin mining for profit, an aspect of Bitcoin responsible for harming the environment through excessive and unproductive use of electricity and resources. Original announcement.
42. SaffronCoin (SFR) (112)
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.
43. LeafCoin (LEAF) (114)
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.
44. Megacoin (MEC) (115)
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.
45. TrollCoin (TROLL) (117)
TrollCoin (TROLL) [formerly TrollCoin (TRL)] is a decentralised, open-source cryptocurrency launched in February 2014 as a fork of Novacoin. It is a hybrid proof-of-work/proof-of-stake (PoW/PoS) coin, using the scrypt algorithm for PoW mining and a static PoS reward of 7 TROLL. Originally TrollCoin's total coin supply was set at 9 billion, but with the release of version 2.0 (in early December 2015), the cryptocurrency was relaunched with a new blockchain and updated parameters. The total coin supply was reduced to 900 million, the proof-of-stake period limited to 7,777,777 blocks, and a proof-of-stake reward system was introduced for the first time. Original announcement.
46. CasinoCoin (CSC) (118)
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.
47. CryptoEscudo (CESC) (121)
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. HoboNickels (HBN) (125)
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.
49. PopularCoin (POP) (126)
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.
