Bitcoin is decentralized digital currency that enables instant payments to anyone, anywhere in the world. Bitcoin uses peer-to-peer technology to operate with no central authority: managing transactions and issuing money are carried out collectively by the network. The original Bitcoin software by Satoshi Nakamoto was released under the MIT license. Most client software, derived or "from scratch", also use open source licensing.
Litecoin is a peer-to-peer Internet currency that enables instant payments to anyone in the world. It is based on the Bitcoin protocol but differs from Bitcoin in that it can be efficiently mined with consumer-grade hardware. Litecoin provides faster transaction confirmations (2.5 minutes on average) and uses a memory-hard, scrypt-based mining proof-of-work algorithm to target the regular computers with GPUs most people already have. The Litecoin network is scheduled to produce 84 million currency units. One of the aims of Litecoin was to provide a mining algorithm that could run at the same time, on the same hardware used to mine Bitcoins. With the rise of specialized ASICs for Bitcoin, Litecoin continues to satisfy these goals. It is unlikely for ASIC mining to be developed for Litecoin until the currency becomes more widely used.
Bytecoin is a first CryptoNote-based cryptocurrency. A CPU-mined coin, it's primary advantages are extraordinary transaction untraceability and unlinkability features. BCN is stated to be much more anonymous than Bitcoin and all its existing forks. The developers claim a person’s right to privacy is their primary concern and strictly observe their own privacy. Bytecoin was started on July 4th, 2012.
Ethereum or Ether is a cryptocurrency designed to pay for the computational purposes of the Ethereum network. The name of the coin comes from the name of the platform intended to allow a network of peers to administer their own stateful user-created smart contracts in the absence of central authority.
QuazarCoin is a new cryptocurrency based on the CryptoNote and uses the CryptoNight algorithm. QCN protects your data and privacy with help of completely anonymous transactions with ring signatures.
Monero is a new coin using the CryptoNote protocol. It's based on Bytecoin, which was coded from scratch and is not a descendent of Bitcoin. XMR was launched on April 18, 2014.
DigitalNote is an experimental open-source cryptocurrency based on CryptoNote technology and CryptoNight algorithm. It is a fork of Bytecoin - the very first implementation of CryptoNote. Nobody own or control DigitalNote. It is a scalable decentralized cryptocurrency with strong privacy protection. DigitalNote uses ring signatures, to provide unlinkable and untraceable transactions.
Dashcoin is a Next generation anonymous cryptocurrency and the first automatically mutating cryptocurrency created with CryptoNote technology.
