Summary
- On Thursday, Base experienced over two hours of downtime due to a problem that interrupted block production.
- The network has resumed operations and is proceeding with a scheduled upgrade.
- In the previous month, there was a partial outage that impacted withdrawals.
Base, the Ethereum layer-2 network developed by the cryptocurrency exchange Coinbase, was offline for more than two hours on Thursday due to a block production issue.
The problem emerged around noon ET, just hours before a planned upgrade, as noted on the network’s status page .
At approximately 12:20 p.m. ET, the network announced on X, "Base Mainnet is currently halted while the team works on an issue with block production. All funds are secure, and we’ll provide updates as soon as possible."
By around 1:00 p.m. ET, the network had pinpointed the issue, but a resolution was still pending.
Blocks are being produced, and we’re observing applications and infrastructure coming back online as their Base nodes are restarted and synchronized.
Recovery should be swift for each application/infrastructure provider once the node restarts are underway.
Thank you for your patience while we resolved this.

The network's status page indicated, "We continue to debug and have isolated a consensus issue that led to an invalid block being sequenced. This blocked the creation of new blocks."
About an hour later, the sequencing of new blocks resumed normally, although the team was still investigating the underlying cause of the disruption.
This incident marks the first block production and deposit problem on the network's mainnet in the last 90 days, as per its status page . However, in May, the network experienced around 30 hours of delays in withdrawals.
A spokesperson for Coinbase has not yet responded to a request for comment from Decrypt.
The network is currently in the process of implementing its Beryl hardfork upgrade, which aims to introduce a new token standard for stablecoins and tokenized real-world assets (RWAs) while also reducing withdrawal delays.
Although blockchain outages are relatively rare, they have occurred periodically, affecting overall network operations. Earlier this year, the layer-1 network Sui experienced outages over three consecutive days due to gas and validator issues on its mainnet. The well-known layer-1 network Solana has also had significant outages in the past, though it hasn’t reported a mainnet problem since February 2024.
