NEO has two native tokens, NEO (abbreviated symbol NEO) and NeoGas (abbreviated symbol GAS).GAS is the fuel token for the realization of NEO network resource control, with a maximum total limit of 100 million. The NEO network charges for the operation and storage of tokens and smart contracts, thereby creating economic incentives for bookkeepers and preventing the abuse of resources. The minimum unit of GAS is 0.00000001.
NEO, with a total of 100 million tokens, represents the right to manage the network. Management rights include voting for bookkeeping, NEO network parameter changes, and so on. The minimum unit of NEO is 1 and tokens cannot be subdivided.
In the genesis block of the NEO network, 100 million NEOs are generated, GAS has not yet been generated. 100 million GAS, corresponding to the 100 million NEO, will be generated through a decay algorithm in about 22 years time to address holding NEO. If NEO is transferred to a new address, the subsequent GAS generated will be credited to the new address.
The NEO network will set a threshold by voting to exempt GAS from a certain amount of transfer transactions and smart contract operations to enhance the user experience. When a large amount of spam transactions occur, NeoID can be used to prioritize transactions and smart contracts with qualified identities. Transactions and smart contracts with no qualifying digital identities can get priority by paying GAS.
