What is Cronos?
Cronos Chain is an open-source public blockchain network that is a fully decentralized, high-speed, low-commission network designed for public use to drive mass adoption of blockchain technology through usage scenarios such as payments, DeFi and NFT.
Native CRO is the Cronos network's own (native) currency, which provides nearly instant CRO transactions with minimal fees.
ERC20 CRO tokens are created and hosted on the Ethereum blockchain, where ETH network commissions are required for cryptocurrency transactions.
