Bitcoin is a digital asset and a payment system that was first published in 2008 and published as an open source software in 2009, invented by a person or a team from Satoshi Nakamoto. System peer-to-peer; Users can directly process without the tool. The transactions are verified by network nodes and saved in a publicly distributed book called block chain. The transactions are verified by network nodes and saved in a publicly distributed distributed book called block chain. The notebook uses bit fatigue as a calculation unit. The system works without a central repository or a single administrator; this led the US Treasury to classify bitmapping as a decentralized virtual currency. Although previous systems exist, Bitcoin is called the first crypto money. Bitcoin is more accurately defined as the first decentralized digital currency. It is the largest of its kind in terms of the total market value.

Litecoin is a peer-to-peer Internet currency that provides instant zero cost payments to everyone in the world. Litecoin is a completely decentralized open-source global payment network without a centralized authority. The mathematical network protects and enables individuals to control their own finances. Litecoin has faster process approval times and improved storage efficiency than the leading math-based currency. Litecoin is a proven business environment that is complementary to Bitcoin with its huge industry support, trade volume and liquidity.

Ethereum is a decentralized platform running smart contracts: applications that are fully programmed and running applications that are not likely to be downtime, censorship, fraud or third-party interference. Ethereum is how the Internet works. In August 2014, Ethereum met with fans from all over the world. It was developed by ETHDEV with contributions from great minds all over the world.

Ripple is a real-time payroll payment system for currency exchange and network. RTXP is called the ripple transaction protocol or the wavelength protocol; It is also called the Ripple Transaction Protocol or the Wavelength protocol; Ripple is based on XRP, a distributed open source Internet protocol, consensus logbook, and local encryption feature. Launched in 2012, Ripple was created to perform secure, immediate and almost completely free financial transactions at any size and without any chargeback.

Monero (XMR) is open source encryption that focuses on privacy, localization and scalability in Windows, macOS, Linux, Android and FreeBSD in April 2014. Monero uses a public ledger to record transactions when new units are created by a process called mining. Monero aims to improve on the existing encryption design by making the amount of sender, receiver and every process done and the mining process more equitable.

Dash (formerly Darkcoin and XCoin) is open-source peer-to-peer encryption. On Bitcoin's feature set, it now offers instant operations, custom operations, and operates a self-managed and self-financing model that allows the Dash network to pay individuals and businesses to pay for a work that adds value to the network. Dash's decentralized governance and budgeting system makes it a decentralized autonomous organization.

DOGE, "Doge" is an encryption feature that has a Shiba Inu dog-like logo from the Internet nozzle. Introduced as a "joke currency" on December 6, 2013, Dogecoin quickly developed its own online community and reached a capital inflow of US $ 60 million in January 2014. As of December 2017, it reached a capital size of USD 1 billion. Dogecoin had a rapid start-up coin production program compared to other crypto currencies: 100 billion coins were circulated in the middle of 2015, and from now on, $ 5,256 billion of coins would continue to be distributed each year.

NEM is a peer-to-peer encryption and blocking platform launched on March 31, 2015. NEM, built with the C ++ version in Java, has a specified target of a wide distribution model and has developed new features to block technology such as the proof of importance (POI) algorithm, multi-signed accounts, encrypted messaging and the like. NEM block chain software is used in a commercial block chain called Mijin which is tested by Japanese financial institutions and private companies.

IOTA is an open source distributed notebook focused on providing secure communication and payment between machines. IOTA, which uses direct acyclic graph (DAG) technology instead of traditional block chain, is a system that is free of charge, independent of the size of the transaction, fast validation times, number of transactions that the system can perform simultaneously and it is easily scalable. IOTA, David Sønstebø, Sergey Ivancheglo, Dominican Schiener and Dr. Founded by Serguei Popov. IOTA is audited by the non-profit organization IOTA to improve technology and ensure that all developers are unlicensed to work together. As of December 2017, the market value of IOTA is $ 9 billion and is the eighth largest cryptographic encryption in the circulation.
