BTC is a cryptocurrency and worldwide payment system. It is the first decentralized digital currency. Its conception is peer-to-peer and transactions take place between users directly, without an intermediary.

It is a hard fork of the cryptocurrency bitcoin. The bitcoin scalability debate led to the hard fork on August 1, 2017, which resulted in the creation of a new blockchain.

A blockchain is a continuously growing list of records, called blocks, which are linked and secured using cryptography. Each block typically contains a cryptographic hash of the previous block, a timestamp and transaction data. By design, a blockchain is inherently resistant to modification of the data. It is "an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way."

A cryptocurrency is a digital asset designed to work as a medium of exchange that uses cryptography to secure its transactions, to control the creation of additional units, and to verify the transfer of assets.

ETH is a cryptocurrency whose blockchain is generated by the Ethereum platform. ETH can be transferred between accounts and used to compensate participant mining nodes for computations performed.

LTC is a peer-to-peer cryptocurrency and open source software project released under the MIT/X11 license. Creation and transfer of coins is based on an open source cryptographic protocol and is not managed by any central authority.

XRP is a cryptocurrency running on a currency exchange and remittance network created by the Ripple company. The network is built upon a distributed open source Internet protocol, consensus.
