According to official news, the Aleph Zero mainnet has been successfully upgraded to version 13.4. In the new version, the maximum supply of Aleph Zero is capped at 520 million AZERO. This change is a key step in achieving greater predictability and long-term stability of the network economy. The new inflation model introduces an exponentially decreasing issuance rate. 27 million AZERO will be issued in the first year after the upgrade, replacing the previous model, which issued 30 million AZERO per year, aiming to gradually reduce inflationary pressure over time.
