Neo formally know as Antshares is a decentralized open sourced cryptocurrency and blockchain platform aiming to utilize blockchain and digital identity to digital assets and automating the task of managing these digital assets using smart contracts. Their vision is to build a smart economy on blockchain. Speaking of how Neo works, it uses a improved version of Proof-of-Stake consensus mechanism called Delegated Byzantine Fault Tolerance (DBFT) which makes Neo Hard Fork proof, meaning blocks cannot be split, transactions cannot be revoked or rolled backed once finalized. Apart from the Neo coin, there is one more token in the Neo network called NeoGAS which is the fuel that drives smart contracts in the Neo network. Gas is generated with each block and collected gas is distributed among the holders of Neo coin proportional to their share of the network. Gas generated from the transactional fees are used to incentivize Consensus nodes for keeping the network up and running. An interesting point to note here is that unlike Neo, Gas is divisible up to 8 decimal places.
