Coordinated under BEP-673, the upgrade integrates three specific proposals—BEP-682, BEP-695, and BEP-675—to improve ~~the network’s~~ security, governance, and throughput. Security enhancements focus on cross-chain bridge verification by rejecting duplicate validator signatures to prevent voting power ~~inflation.~~ inflation (BEP-682). Governance and staking are also being strengthened through ~~stricter validator key management, ensuring~~ BEP-695, which ensures retired consensus keys lose administrative authority and blacklisted addresses are barred from signature-based governance votes. To increase transaction capacity, ~~the upgrade~~ BEP-675 modifies the block production ~~process. By~~ process by allowing builders to submit fully executed blocks for validator ~~review,~~ review. While the ~~network aims to reduce processing time. Testnet~~ 450-millisecond block interval remains unchanged, testnet benchmarks ~~indicate~~ indicated that ~~this optimization~~ validator processing time could ~~significantly~~ drop from 125 milliseconds to 15 milliseconds. This optimization aims to increase transaction ~~throughput, potentially raising speeds~~ throughput from approximately 1,237 transactions per second (TPS) to 2,324 TPS. ~~To prepare for the activation, node~~ Node operators ~~are~~ were required to upgrade to version ~~1.7.7.~~ 1.7.7 prior to activation.
