Neo N3 Network Update: 3-Second Block Time and GAS Adjustment
The Neo Council has approved and executed a proposal on Neo N3 MainNet to reduce block generation time to 3 seconds (setMillisecondsPerBlock=3000) and adjust GAS issuance to 1 GAS per block (setGasPerBlock=100000000).
Block time improves network responsiveness and transaction finality, while GAS per block ensures the GAS issuance rate remains stable.
The governance action bundled two chained native contract invocations into a single atomic proposal executed via the Policy contract. The proposal passed with 13 out of 21 Council votes, exceeding the required quorum of 11.

This update optimizes Neo N3 for future network demand and represents a strong example of decentralized governance in action, where Council members collaborate to make coordinated protocol-level decisions in the long-term interest of the Neo ecosystem.
