EOS is a cryptocurrency designed to support large-scale applications. There are no fees to send or receive EOS. Instead, the protocol rewards the entities that run the network periodically with new EOS, effectively substituting inflation for transaction fees.
EOS is the native cryptocurrency for the EOS.IO blockchain platform with smart contract capabilities. The company Block.one created EOS.IO in September 2017 and it now has over 100 dapps with thousands of daily active users. It enables decentralized apps, or dapps, to be created by software developers. The platform is more scalable than many other blockchain networks, with the ability to process one million transactions per second without any fees.
Its dapp development capability makes EOS similar to Ethereum with the notable distinction that transaction confirmations are done through a different type of consensus system. Block producers are chosen by the EOS ecosystem through a voting mechanism known as delegated-proof-of-stake (DPoS). In order to vote, users must stake tokens for three days without selling them, putting them at risk of losing money should the price of the token drop during that time.
There is no maximum supply limit of EOS tokens. The delegated proof-of-stake model uses inflation, capped at 5% annually, to fund transactions and pay block users.
