SKN | Coinbase’s Base Blockchain Recovers After Two-Hour Outage Caused by Consensus Failure

• Coinbase-backed layer-2 network Base resumed normal operations after a nearly two-hour outage caused by a consensus issue that halted block production.

• The network identified an invalid block sequencing event as the cause, preventing new blocks from being created until engineers restored healthy block production.

• The outage occurred just hours before Base successfully completed its scheduled Beryl network upgrade, which introduces faster withdrawals and new token standards.

• Despite the disruption, Base confirmed that all user funds remained secure and pledged to release a full post-mortem explaining the incident.

Base Network Suffers Rare Block Production Halt

Coinbase-backed Ethereum layer-2 blockchain Base returned to normal operations after experiencing a rare network outage that temporarily halted block production for nearly two hours.

The issue began when Base engineers detected unhealthy block production across the network. After investigating the disruption, the team determined that an invalid block had been sequenced due to a consensus problem, preventing new blocks from being produced.

Engineers isolated the issue, restored healthy block building, and synchronized network infrastructure before confirming that the ecosystem had fully recovered.

The development marks one of the few significant outages experienced by Base since its launch.

Consensus Issue Temporarily Stopped the Network

According to Base’s engineering team, the disruption originated from a consensus failure that allowed an invalid block to enter the sequencing process.

Because Ethereum layer-2 networks rely on continuous block sequencing to process transactions, the invalid block prevented subsequent blocks from being generated until the issue was resolved.

Following the recovery, Base confirmed that healthy block production had resumed across the network and stated that a detailed post-mortem will be released after engineers complete their investigation into the root cause.

User Funds Remained Safe Throughout the Incident

Base creator Jesse Pollack reassured users that no customer funds were at risk during the outage.

While acknowledging that any network halt is unacceptable, Pollack said the incident provides an opportunity to further strengthen Base as infrastructure designed for continuous, around-the-clock global financial applications.

The network emphasized that the interruption affected transaction processing rather than the safety or integrity of assets stored on the blockchain.

Beryl Upgrade Successfully Completed

The outage occurred only hours before Base’s scheduled Beryl network upgrade, which proceeded successfully after services were restored.

The Beryl upgrade introduces several enhancements aimed at improving network performance and institutional adoption.

Among the key improvements are reduced withdrawal waiting times and support for a new token standard designed specifically for tokenized real-world assets and stablecoins.

These upgrades reflect Base’s broader strategy of expanding beyond traditional crypto applications toward institutional blockchain infrastructure.

Blockchain Reliability Remains in Focus

Although major blockchain outages remain relatively uncommon, the incident highlights the operational challenges facing rapidly growing blockchain networks.

Base previously experienced a shorter outage lasting approximately 33 minutes in August 2025.

Other blockchain ecosystems have encountered similar issues. Earlier this year, layer-1 network Sui experienced multiple temporary outages following a network update that unexpectedly interrupted block production.

As blockchain adoption grows, network reliability, redundancy, and consensus resilience continue to be major priorities for developers supporting financial applications that operate around the clock.

Outlook

Base’s quick recovery demonstrates the growing operational maturity of major blockchain infrastructure providers, but the outage also serves as a reminder that even leading networks remain vulnerable to technical failures. As decentralized finance, tokenized assets, and institutional blockchain applications continue expanding, maintaining uninterrupted network availability will become increasingly critical to supporting global financial activity.
