Last night, Base Chain experienced a 33 minute network disruption that halted block production.
This was due to an automatic handoff to an unhealthy mainnet sequencer in the high-availability cluster. We quickly switched to a healthy mainnet sequencer and Base Chain resumed normal operation.
We have run a full postmortem to share what happened, how we addressed the issue, and the steps we are taking to prevent similar incidents in the future.
Fusaka is coming to Ethereum and bringing more blobs for @base users with it.
Time for a technical deep dive 🧵
We'll go over why this work is important and what Base has been doing to accelerate Fusaka’s timeline in collaboration with @OPLabsPBC, @testinprod_io, and @soneium
First, some background:
Blob TXs were introduced by EIP-4844 in the Dencun upgrade and brought data availability (DA) fees paid by rollup users down by >100x
May’s Pectra upgrade doubled the blob target/block from 3 to 6, which opened up much needed throughput for rollups
Fusaka will allow Ethereum to ramp up to a target of up to 48 blobs/block on a scheduled and safe basis via PeerDAS and BPO hardforks
Why PeerDAS?
Rollups have proven to be an effective way to scale Ethereum and onboard many additional users. Ethereum L1 only provides 96 KiB/s DA at current blob limit, which equates to ~1000 tx/s across all rollups.
PeerDAS helps scale Ethereum by allowing beacon nodes to sample a subset of rollup blob data (instead of all of it), which allows the L1 to handle more blob throughput overall.
PeerDAS will allow blob throughput to scale by ~8x, while keeping user fees low!
This 10x change makes Base the fastest EVM chain to date, bringing effective block times from 2 seconds down to 200 milliseconds —and they're live on testnet right now + coming to mainnet in Q2
Flashblocks are sub-blocks issued by the block builder and streamed to nodes every 200ms, allowing for early confirmation times with native revert protection
