The following cryptocoins match your criteria (sorted by popularity):
1. Monero (XMR) (1)
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.
2. Bitcoin (BTC) (3)
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.
3. Decred (DCR) (5)
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.
4. Stellar Lumen (XLM) (6)
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.
5. Lisk (LSK) (18)
6. Dogecoin (DOGE) (24)
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) (29)
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. Counterparty (XCP) (31)
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.
9. DigiByte (DGB) (36)
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.
10. Unobtanium (UNO) (39)
11. Vertcoin (VTC) (41)
12. Nxt (NXT) (42)
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. The next major release will also allow users the creation of new currencies within the system. Original announcement.
13. OKCash (OK) (45)
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.
14. Auroracoin (AUR) (46)
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.
15. Omni (OMNI) (47)
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.
16. VERGE (XVG) (48)
17. PotCoin (POT) (57)
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.
18. Peercoin (PPC) (61)
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.
19. BitCrystals (BCY) (65)
BitCrystals (BCY) are digital assets acting as both the game-fuel and the premium in-game currency in EverdreamSoft's Spells of Genesis game. BitCrystals were issued in February 2015 in a limited supply of 100 million units, 70% of which were offered for purchase during the initial BitCrystals crowdsale. BitCrystals can be traded on the Counterparty blockchain or used to purchase blockchain-based cards, playable within Moonga and Spells of Genesis. As an asset issued on the Counterparty (XCP) platform, the project does not provide an independent wallet, although a client is available from Google's Chrome Web Store as an extension for the Chrome and Chromium web browsers. Original announcement.
20. MonetaryUnit (MUE) (66)
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.
21. 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.
22. Viacoin (VIA) (84)
23. GoldBlocks (GB) (87)
GoldBlocks (GB) is a decentralised, open-source cryptocurrency forked from BlackCoin in May 2016. It's a hybrid proof-of-work/proof-of-stake (PoW/PoS) coin which can be either "mined" by a computer or "minted" through a process called "staking". The PoW part of the coin uses the X11 hashing algorithm (11 rounds of scientific hashing functions that include blake, bmw, groestl, jh, keccak, skein, luffa, cubehash, shavite, simd and echo) with a 60-second block time and a total coin supply of 24.7 million. The coin's PoS method offers a 10% annual interest on staked coins, with the total supply capped at 50 million coins. Original announcement.
24. Groestlcoin (GRS) (88)
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.
25. Paycoin (XPY) (90)
Paycoin (XPY) is a decentralised open-source cryptocurrency forked from Bitcoin and launched in late 2014 by the founders of GAWMiner.com, a well-known provider of Bitcoin mining products. The project's ambition is to deliver a cryptocoin that would be accepted by the non-technical public and seamlessly integrated into existing payment systems, both online and in physical stores, via a physical debit card. The price of Paycoin plummeted shortly after its launch, leading to allegation of a "pump-and-dump" scheme and subsequent removal of Paycoin from a popular exchange.
26. StartCOIN (START) (92)
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.
27. Titcoin (TIT) (93)
Titcoin (TIT) is a decentralised, open-source cryptocurrency launched in June 2014 as a customised fork of Bitcoin. It was designed specifically for the adult entertainment industry where privacy and anonymity are key consumer factors, while also giving consumers the ability to make discreet micropayments that carry extremely low transaction fees. Technically, Titcoin is similar to Bitcoin with some key differences, such as improved transaction speeds, modified network difficulty adjustment, higher number of coins rewarded per block (69 TIT), and higher total supply of coins (69 million TIT compared to 21 million BTC). Titcoin is notable for being the first altcoin fully recognized as a legitimate form of currency by a major industry trade organization. Original announcement.
28. Fluttercoin (FLT) (100)
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.
29. Megacoin (MEC) (110)
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. FIMKrypto (FIMK) (118)
FIMKrypto (FIMK) is an open-source cryptocurrency and payment network forked from (and compatible with) Nxt (NXT) in July 2014. It is intended as a national cryptocurrency of Finland, with a goal of offering all Finnish citizens a regular basic income. Besides being a modern cryptocurrency platform, FIMKrypto also provides numerous useful decentralised functions, such as direct transmissions of payments from person to person, strongly encrypted private messaging, and other features. As with most cryptocurrencies, nodes running the FIMK wallet software are eligible to compete for block rewards that are distributed automatically every 30 seconds. Original announcement.
31. Steps (STEPS) (122)
Steps (STEPS) is a decentralised open-source cryptocurrency launched in September 2015 as a fork of Novacoin. It is a pure proof-of-stake (PoS) coin which pays a variable interest rate depending on the amount of "staked" coins; starting from block 60,100 the PoS interest will be set to 1%. The project's future plans include various additional services, such cryptocurrency trading platform, payment gateway and web wallet. Original announcement.
