About Gas
Neo's GAS is generated with the construction of the NEO blockchain. Around the year 2039, GAS circulation will reach 100 million and production will cease. The finite limit on GAS may cause the price to rise over time. GAS dividends are also accumulated as fees to the NEO network. Users pay with GAS to deploy and run smart contracts. Fees are proportional to the computing resources consumed by the contract. These fees are distributed as a reward for their activity on the network.
