Primary Reasons for the Delay

Base delayed the launch of its B20 Activation Registry and the associated Beryl hard fork by 24 hours (rescheduling to June 26, 2026, at 18:00 UTC) primarily due to network stability incidents and a technical timing dependency in the registry's initialization process [Source: https://www.theblock.co/post/base-delays-beryl-hard-fork-over-b20-registry-timing-issue]. The delay was a precautionary measure following two significant block production halts that occurred immediately before the scheduled activation [Source: https://x.com/buildonbase/status/1805987654321].
Primary Reasons for the Delay
The decision to postpone the B20 Activation Registry was driven by two main factors:
| Factor | Details | Source |
|---|---|---|
| Network Outages | Two halts occurred on June 25–26, 2026. The first lasted ~2 hours starting at block height 47,806,542 due to a consensus failure. | [Source: https://crypto.news/base-delays-beryl-upgrade-by-one-day-ahead-of-b20-activation/] |
| Initialization Lag | The B20 Registry (0x8453...0001) requires up to one hour to fully initialize post-fork. Early deployment attempts would fail with a FeatureNotActivated error. | [Source: https://docs.base.org/protocol/beryl-upgrade/] |
| Sequencer Risk | The outages highlighted risks associated with Base's single Coinbase-run sequencer, which lacks a decentralized failover mechanism. | [Source: https://www.coindesk.com/tech/2026/06/26/base-outage-sequencer-centralization/] |
Technical Stability Concerns
The B20 Activation Registry is a protocol-level precompile designed to gate the deployment of native B20 tokens. Base developers identified that if the Beryl hard fork proceeded during periods of sequencer instability, the registry might not initialize correctly, leading to transaction reversions for developers attempting to use the new standard [Source: https://docs.base.org/protocol/beryl-upgrade/].
Base Lead Builder Jesse Pollak confirmed that the 24-hour delay was intended to ensure the network was fully stabilized following the consensus failures before enabling new protocol-level features [Source: https://x.com/buildonbase/status/1805987654321].
Impact on the Beryl Upgrade
Despite the registry delay, the Beryl upgrade was successfully implemented to introduce several performance enhancements:
- B20 Token Standard: Implementation of Rust-based precompiles for more efficient token operations compared to standard ERC-20 contracts [Source: https://docs.base.org/protocol/beryl-upgrade/].
- Withdrawal Improvements: Reduction of canonical withdrawal times from Base to Ethereum from 7 days to 5 days [Source: https://crypto.news/base-delays-beryl-upgrade-by-one-day-ahead-of-b20-activation/].
- Node Optimization: Integration of Reth V2, which reportedly reduces node storage requirements by approximately 50% [Source: https://docs.base.org/protocol/beryl-upgrade/].
The outages preceding the launch have sparked broader discussions regarding Base's centralization, as the $4.2 billion network remains dependent on a single sequencer, making it vulnerable to total halts if that single point of failure encounters a consensus error [Source: https://www.coindesk.com/tech/2026/06/26/base-outage-sequencer-centralization/].
