Starknet Restarts Block Production After Outage

Starknet is back online following an outage early Tuesday, with block production restored and most RPC providers functioning again as the remaining nodes upgrade. This information comes from an update shared on social media and activity observed via the blockchain's explorer. Earlier today, the Ethereum Layer 2 network faced several hours of downtime, which suspended on-chain transactions on the zero-knowledge rollup while builders addressed the problem. The project acknowledged the situation with a statement saying, 'Starknet is currently experiencing downtime.' Starknet operates as a ZK Layer 2 blockchain that batches transactions off-chain and posts cryptographic proofs to Ethereum. Its aim is to reduce fees and enhance throughput while benefiting from Ethereum's security. To stabilize the network, developers executed a chain reorganization from block No. 1,960,612, which involved roughly one hour of activity. They indicated that the chain did not process transactions submitted between 2:23 a.m. and 4:36 a.m. UTC as developers prioritized restoring regular services. Users whose transactions do not appear on-chain may need to resubmit them. A comprehensive analysis of the incident is planned, with a detailed retrospective on the full timeline, root cause, and long-term prevention measures to follow. This outage occurred as Starknet introduces new initiatives, including a recently approved measure granting bitcoin stakers limited influence in consensus, and continuous efforts on its SN Stack for app chain development. Multi-hour disruptions are rare on Starknet. QuickNode status data indicates 100% uptime in recent months, aside from a brief hiccup in July lasting around 15 minutes. The last similar unplanned outage was on April 5, 2024, lasting four hours due to a rounding error bug that triggered a chain reorganization.
