BNB Chain has introduced BEP-675, a draft proposal aimed at improving network throughput by reducing block re-execution in the validator process. The change could cut validator execution time on the critical path from 125 milliseconds to 15 milliseconds, and testnet environments show a potential doubling of throughput.
How blind signing changes block validation
BEP-675 introduces blind signing for validator blocks, allowing builders to submit executed blocks directly. Instead of validators re-running the entire block execution, they can sign off on a block that's already been processed. That removes a heavy step from the critical path, which is why the time drops so dramatically.
The proposal targets the block construction and validation workflow specifically. It doesn't rely on higher gas limits or shorter block times to squeeze out more capacity. It's a more surgical fix to the bottleneck that slows down the network.
What the testnet results suggest
On testnet, the numbers look promising. The proposal could double throughput, according to the draft. That's a significant gain for a network that processes a high volume of transactions. But the key word here is "could." The testnet isn't the mainnet, and real-world conditions can throw curveballs.
Still, the reduction from 125ms to 15ms is a big deal. It means validators spend far less time on each block, which frees up resources and lets the network handle more transactions in the same window.
Draft status and the Pasteur hard fork
BEP-675 is not live on BNB Chain mainnet. It remains in Draft status under the Pasteur network hard fork timeline. That means it's still being reviewed and tested. The community will need to weigh in, and the code will need to prove itself before any deployment.
The proposal is a technical scaling measure with real potential, but it's not a done deal. It's a draft, and drafts change. The next step is for the BNB Chain community to review the proposal and for further testing to happen on testnet. If it holds up, it could be part of the Pasteur hard fork, but that timeline hasn't been set in stone.
