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.
Zcash is a decentralized privacy-centered currency, allowing users to partly conceal the details of their transactions, such as sending and receiving parties and the amount. It is possible due to innovative technology the developers have come up with, zero-knowledge proving. Zcash is a fork of Bitcoin protocol, thus they share some similarities, such as the total amount of coins to be minted and block reward halvings. Advanced privacy is the main major improvement.
Ethereum is currently the most ambitious blockchain project. It runs its own cryptocurrency, called Ether, but goes beyond being just digital currency. Ethereum is a decentralized platform that allows building smart contracts: decentralized applications (dapps) that run as they coded without any possibility of censorship, downtime, fraud or third parties interference. The applications can move value through Blockchain and represent the ownership of property. The big idea behind Ethereum has attracted millions of users (crypto-enthusiasts, miners, investors) and boosted the market value of Ether coins, making it the most popular cryptocurrency after Bitcoin.
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. BCN is based on CryptoNote, an open-source technology for anonymous cryptocurrencies. It utilizes ring signature and one-time addresses for completely anonymous payments. CryptoNote is designed in a way, which makes block chain analysis impossible. CryptoNote is focused on CPU-mining in order to make the special purposes devices useless.
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.
AEON coin [AEON]
AEON coin is the anonymous cryptocurrency which is based on the CryptoNote protocol and uses the CryptoNight algorithm.
PascalCoin is a new cryptocurrency written from scratch, and is designed to work without an operations history, yet is able to control double spending or check balance. Instead of storing balances on the blockchain, PascalCoin offers a safebox system similar to a bank account.Pascal Coin is a cryptocurrency for humans, not only for geeks. Since its account system is very similar to a bank account by design, PascalCoin is an easy to understand and easy to work with cryptocurrency. Through easy to remember account numbers instead of cryptographic addresses, everybody can have an overview of how it is designed.
