BSC Confirms Pasteur Hard Fork Release Date at the End of August
BNB Chain has confirmed that the Pasteur hard fork for the BNB Smart Chain (BSC) mainnet will activate at 02:30 UTC on August 25, 2026. Node operators must upgrade to client version 1.7.7 by that time to avoid network disconnection.
The hard fork, packaged under the BEP-673 meta-proposal, consolidates three other proposals: BEP-682, BEP-695, and BEP-675.
BEP-682 aims to secure cross-chain bridges by fixing a vulnerability where validator signatures in asset transfers could be counted multiple times, allowing a threshold to be met with fewer genuine signatures. The update ensures duplicate signatures are removed before counting.
BEP-695 addresses a flaw in staking and governance systems where a validator's old consensus key, after being rotated for maintenance, could retain its administrative privileges. The fix ensures retired keys immediately lose their authority and prevents validators from avoiding slashing through key rotation.
BEP-675 aims to increase network throughput. It allows a block proposer to submit a pre-executed block, reducing the time validators spend re-executing transactions. Testnet results showed validator execution time dropped from 125ms to 15ms, and throughput increased by nearly 88% to 2,324 TPS, with average block gas usage rising significantly.
Node operators must follow detailed upgrade procedures. Developers using the BEP-675 scheme may need to run a full node instead of a light client, as they are now responsible for creating fully executed blocks.
