GAS is generated with each new block. With the increasing rate of new block generation, the total limit of 100 million GAS will be achieved in about 22 years.

Each year around 2 million blocks will be generated and the initial generation will be 8 GAS per block. There will be an annual reduction of 1 GAS per block, per year, to coincide with the passing of every 2 million blocks. The reduction will continue down to just 1 GAS per block and will be held at that rate for around 22 years. After the 44 millionth block the total GAS generated will have reached 100 million and from this point there will be no further generation of GAS from new blocks. According to this release curve, 16% of the GAS will be created in the first year, 52% of the GAS will be created in the first four years, and 80% of the GAS will be created in the first 12 years.

These GAS will be distributed proportionally in accordance with the NEO holding ratio, recorded in the corresponding addresses. NEO holders can initiate a claim transaction at any time and claim these GAS tokens at their holding addresses.
