Base Delays Important Upgrade After Back-to-Back Network Outages
Base's B20 token standard was set to open for issuers on June 26, but a second chain stall in two days has delayed the B20 token launch.
The network finished its Beryl upgrade on June 25, which carries B20 alongside faster withdrawals and lighter node software. Switching on B20 issuance depends on a separate registry that Base has not confirmed live.
Back-to-Back Stalls Revive Sequencer Concerns
Base block production turned unhealthy on June 26, hours before B20 was due to activate at 6pm UTC. The team reported a chain halt with symptoms matching the previous day and restored blocks in about 15 minutes.
A day earlier, an invalid block froze the sequencer at block 47,806,542 and stopped production for close to two hours. Recovery both times required ecosystem node operators to restart their machines.
Neither stall touched user funds, which stay settled on Ethereum. The repeat failures instead put scrutiny back on the sequencer, the single Coinbase-run engine that orders Base transactions.
Base reached Stage 1 decentralization in 2025 with fault proofs and a 10-member security council. Those changes hardened proofs and upgrades, not the lone sequencer that stalled.
The network ran nearly two years without a halt until a 20-minute outage in August 2025 first flagged its sequencer centralization risk. The June stalls now hit the largest Ethereum Layer 2, which holds about $4 billion in deposits, per DefiLlama.

B20 Launch Waits on the Activation Registry
B20 is built into Base, Coinbase's Layer 2 network, as node software rather than a deployed contract. It mirrors the ERC-20 standard, so wallets and exchanges need no changes.
Base documentation said B20 issuance was anticipated for 6pm UTC on June 26, then up to an hour for its activation registry to switch on. Until that happens, deployment calls revert.
With the recent network stability issues, we're pushing back the B20 Activation Registry mainnet enablement to ensure a smooth rollout. Sepolia and Vibenet remain on track.
We'll share a revised date shortly.— Base Build (@buildonbase) June 26, 2026
The standard targets stablecoin and real-world asset issuers with built-in supply caps, roles, and transfer policies. Base still issues no native token, yet now markets itself as an issuance venue.
Beryl also cut canonical withdrawals to Ethereum from seven days to five, freeing capital for bridging providers sooner.
What to watch
Base has promised a full post-mortem on the consensus bug behind both halts. Whether it enables B20 before fixing the repeat stalls will test Base's scaling roadmap, which courts institutional issuers.
