What Beryl Actually Changes. The hard fork targets two core areas: the consensus mechanism and block size parameters.

Why Sepolia, Why Now. The Sepolia testnet is well-suited for this kind of work.

What Comes After the Testnet. After the Sepolia activation, developers will run a thorough assessment.

Coinbase's Layer 2 network, Base, is pushing a hard fork to the Sepolia testnet. The upgrade is called Beryl, and it's basically the next step in a longer roadmap to make the…

The activation was set for June 18 on Sepolia — not mainnet, not yet. That distinction matters.

The hard fork targets two core areas: the consensus mechanism and block size parameters. Both changes are designed to push transaction throughput higher and cut latency down.

Layer 2 networks live and die on throughput. Base competes in a pretty crowded space — Arbitrum, Optimism, zkSync and others are all chasing the same users and developers.

The consensus mechanism adjustment is the more technically sensitive piece. Changes there can have ripple effects that don't always show up immediately.

The Sepolia testnet is well-suited for this kind of work. It mirrors mainnet conditions closely enough to generate useful data, but mistakes there don't cost anyone real money.

And the scale question is real. Demand on Base has grown since launch, and the infrastructure has to keep pace.
14 / 15
After the Sepolia activation, developers will run a thorough assessment. No rubber-stamping here — if the data shows problems, the fork doesn't move forward until they're fixed.

So the short version: Beryl goes live on Sepolia June 18, developers watch it closely, and the mainnet question stays open until the results come in.
