The opBNB community has accomplished a mainnet laborious fork that was launched on the testnet early Tuesday morning. The Fourier mainnet laborious fork was then migrated to mainnet round 03:00 UTC on Wednesday, and former Binance CEO Changpeng Zhao confirmed its completion an hour later.
In line with opBNB Community Improve: memo GitHub has halved blocking occasions from 500ms to 250ms with the Fourier laborious fork, and has applied a number of adjustments to enhance stability, finality dealing with, and node efficiency.
opBNB is a layer 2 Ethereum Digital Machine (EVM) suitable community constructed utilizing an OP stack that extends functions on top of the BNB chain. The blockchain has a block measurement of 100 million gasoline and options constantly low transaction charges with an emphasis on excessive throughput.
Fourier improve reduces block spacing and fixes P2P node derivation
As praised by Zhao in at this time’s X put up, the primary change delivered by the Fourier laborious fork was the implementation through pull request #305, which lower the block interval in half. Decreasing block occasions to 250 milliseconds means opBNB improves transaction processing pace and responsiveness for functions deployed on the community.
opBNB simply accomplished a mainnet laborious fork about an hour in the past. Block time diminished from 500ms to 250ms.

Shorter block intervals additionally scale back affirmation time, making interactions really feel nearer to real-time for customers and builders. Nonetheless, node operators had been instructed to improve op-geth to model 0.5.9 to take care of blockchain compatibility with the brand new protocol guidelines.
One other change has come Pull request #319This fixes the way in which the community handles layer 1 references utilized by the sequencer and derivation logic. opBNB now makes use of the ultimate layer 1 block as a reference level as a substitute of counting on the most recent layer 1 head.
This adjustment addresses anticipated adjustments within the BNB Sensible Chain, the place block occasions are set to drop to 450ms. Validators can generate as much as 16 consecutive blocks beneath new circumstances. Nevertheless, large-scale reorganizations require increased affirmation thresholds on each validators and sequencers, which might delay deposit transactions by a number of minutes.
In line with BNB developer Joey Chang, the Fourier laborious fork additionally bundles a number of fixes that impression node reliability by including assist for compiling opBNB with Golang model 1.24.x and compatibility with Home windows working programs.
Pull request #324 mounted an error in block quantity calculation that would happen throughout lengthy shutdowns, and lengthy outages now full accurately on restart. If a node is down for a protracted time frame, block calculations could also be incorrect when restarted.
Resolved a problem that affected nodes working op-geth in fastnode mode as a result of a tough fork, stopping them from retaining full state knowledge. When a compute node makes an attempt to derive a brand new block utilizing the engine API, empty block roots can happen as a result of lacking state info.
This failure precipitated the op-node’s essential loop to exit and cease block synchronization, however the repair now could be that in fastnode mode, the op-node will watch for insecure blocks from the peer-to-peer community with out requesting block derivation from the op-geth.
Additional fixes embrace resolving the map concurrency difficulty in reference metrics through pull request #326 and including Fourier hardfork timestamps to mainnet parameters through pull request #328.
BNB Chain information 40% improve in TVL in 2025, token maintains $900 stage
The opBNB improve comes towards the backdrop of an lively 12 months for the Binance Chain ecosystem, with end-2025 statistics exhibiting TVL rising by 40.5% year-on-year and each day buying and selling quantity reaching 10.78 million. report.
The BNB Chain has over 700 million distinctive addresses, and each BNB Sensible Chain and opBNB have averaged over 4 million each day lively customers. BNB, the blockchain’s native token, not too long ago broke by the $910 resistance zone and rose practically 2% to commerce above $920 as the remainder of the cryptocurrency market continues its restoration.
As of this report, BNB is up 5% over the previous seven days and is 33% off its all-time excessive of $1,370 reached final October. BNB reached an intraday excessive of $921.47, however a value correction pushed the value again under the following technical resistance at $918.
This value transfer comes forward of the Fermi laborious fork scheduled for January 14th, which is predicted to extend the processing capability of the BNB chain to twenty,000 transactions per second.
