The opBNB community has accomplished a mainnet exhausting fork that was launched on the testnet early Tuesday morning. The Fourier mainnet exhausting 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 response to opBNB Community Improve: memo GitHub has halved blocking instances from 500ms to 250ms with the Fourier exhausting fork, and has applied a number of modifications to enhance stability, finality dealing with, and node efficiency.
opBNB is a layer 2 Ethereum Digital Machine (EVM) appropriate community constructed utilizing an OP stack that extends purposes 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 right now’s X publish, the primary change delivered by means of the Fourier exhausting fork was the implementation by way of pull request #305, which reduce the block interval in half. Lowering block instances to 250 milliseconds means opBNB improves transaction processing pace and responsiveness for purposes deployed on the community.
opBNB simply accomplished a mainnet exhausting fork about an hour in the past. Block time lowered 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 keep up 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 an alternative of counting on the newest layer 1 head.
This adjustment addresses anticipated modifications within the BNB Sensible Chain, the place block instances are set to drop to 450ms. Validators can generate as much as 16 consecutive blocks underneath new situations. Nonetheless, large-scale reorganizations require greater affirmation thresholds on each validators and sequencers, which might delay deposit transactions by a number of minutes.
In response to BNB developer Joey Chang, the Fourier exhausting fork additionally bundles a number of fixes that impression node reliability by including help for compiling opBNB with Golang model 1.24.x and compatibility with Home windows working programs.
Pull request #324 fastened an error in block quantity calculation that would happen throughout lengthy shutdowns, and lengthy outages now full appropriately 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 operating op-geth in fastnode mode resulting from 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 resulting from lacking state info.
This failure induced the op-node’s foremost loop to exit and cease block synchronization, however the repair now’s that in fastnode mode, the op-node will anticipate insecure blocks from the peer-to-peer community with out requesting block derivation from the op-geth.
Additional fixes embrace resolving the map concurrency concern in reference metrics by way of pull request #326 and including Fourier hardfork timestamps to mainnet parameters by way of pull request #328.
BNB Chain data 40% improve in TVL in 2025, token maintains $900 degree
The opBNB improve comes towards the backdrop of an energetic yr for the Binance Chain ecosystem, with end-2025 statistics exhibiting TVL growing by 40.5% year-on-year and day by 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 day by day energetic customers. BNB, the blockchain’s native token, not too long ago broke by means of 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 worth correction pushed the value again beneath the following technical resistance at $918.
This worth transfer comes forward of the Fermi exhausting fork scheduled for January 14th, which is predicted to extend the processing capability of the BNB chain to twenty,000 transactions per second.
