@base is hitting pause on a milestone upgrade. After suffering two block-production halts within 24 hours, @coinbase's layer-2 network has postponed the mainnet launch of its B20 Activation Registry, the gateway to its new token standard for stablecoins and real-world assets.
The trouble began on June 25, when the first outage hit at approximately 16:03 UTC, triggered by a consensus failure linked to an invalid block sequence detected after block height 47,806,542.Block production remained stalled for roughly two hours before the team restored operations. Then, around 15:34 UTC on June 26, a second halt struck with what appears to be a similar root cause. Friday's stoppage cleared in about 14 minutes, but the back-to-back failures were enough to push the mainnet activation off the schedule entirely.
The timing was particularly pointed. Base had just scheduled its second major network upgrade, called Beryl, which introduces the B20 native token standard and cuts Ethereum withdrawal delays from seven to five days, for June 25 mainnet activation.B20 is a native token standard built directly into node software rather than deployed as a smart contract, making token issuance more efficient for stablecoins and real-world asset projects.
Base runs on a centralized sequencer, the single entity responsible for ordering transactions and producing blocks. When it fails, the entire network stops. There is no fallback, no committee of validators that can pick up the slack.The central tension the Base team now faces is that a network positioned as critical financial infrastructure remains dependent on a single sequencer, meaning a single bad block can bring the whole chain to a standstill.
No user funds were reported at risk during either incident. Base creator Jesse Pollak acknowledged the seriousness of the situation, stating that funds were safe "but a halt is not okay, and we'll use this to continue to level up Base as a platform for global, 24/7 finance."The development team has said it is actively investigating both incidents and preparing post-mortem analyses. Base confirmed that testnets remain on track and that a revised mainnet date for the B20 Activation Registry is forthcoming.
The network has scheduled Cobalt, its subsequent major upgrade, for September, which is expected to deliver account abstraction capabilities, smart account support, gas sponsorship, transaction batching, and expanded B20 features.
