NEO is a community-driven open source platform. Using blockchain technology and digital identity, developers can digitize and automate asset management through smart contracts. Based on blockchain technology, NEO converts real-world assets into digital assets, realizes intelligent management through smart contracts, and users select digital certificate certification agencies to realize identity authentication. NEO is used to realize the management rights of the NEO network. NEO is one of the public chain projects with relatively high popularity in domestic and foreign communities. The NEO blockchain combines a series of technologies such as peer-to-peer networks, Byzantine fault tolerance, digital certificates, smart contracts, superconducting transactions, and cross-chain interoperability protocols to allow you to manage your smart assets quickly, efficiently, safely, and legally. NEO has two native tokens built in, NEO (abbreviated symbol NEO) and NeoGas (abbreviated symbol GAS). NEO is a management token with a total of 100 million copies, which is used to realize the management rights of the NEO network. Management rights include voting for bookkeeper elections and changing NEO network parameters. The minimum unit of NEO is 1, which cannot be divided. GAS is a fuel token with a maximum total limit of 100 million, which is used to realize resource control when using the NEO network. The NEO network charges fees for token transfers and the operation and storage of smart contracts, thereby providing economic incentives for bookkeepers and preventing resource abuse. The minimum unit of GAS is 0.00000001.
