Neo, formerly known as Antshares, is an open-source community-driven blockchain platform developed in 2014.The MainNet of Neo was introduced in October 2016 and uses a unique dual-token concept with NEO and GAS tokens. While NEO is the specialized network token, GAS tokens are utilized to conduct Neo blockchain transactions and are distributed by storing NEO in wallets.Neo's technology is driven by its dBFT (Delegated Byzantine Fault Tolerance) consensus algorithm, which tries to prevent untrustworthy players from participating in the blockchain's operation, and incorporates the usage of the NeoVM with smart-contract functionality.
