Ethereum layer 2 StarkNet hit by 4-hour outage after upgrade

Ethereum’s Layer 2 blockchain network StarkNet suffered an unexpected outage on Tuesday following its Grinta ￰0￱ recent updates, some services have been down for more than three hours, but the team partially recovered others after 20 ￰1￱ to an update from the blockchain’s developers made on X earlier today, the service interruption occurred shortly after StarkNet rolled out its Grinta upgrade, also known as StarkNet v0.14.0, around 6:00 AM ￰2￱ a statement posted on X on Sunday, StarkNet cautioned users that there would be a short downtime, explaining that transactions would not be processed during the Grinta upgrade ￰3￱ team had estimated about 15 minutes of disruption but admitted that more risks could be involved.

“Our team is actively investigating the issue and working to restore full functionality as quickly as possible. We’ll share updates as soon as we know ￰4￱ you for your patience,” StarkNet ￰5￱ Coingecko data, StakNet’s native token STRK fell by more than 3% in the last day to trade at $0.1232, possibly due to the network issues.. Incident timeline and status updates Even after the team gave assurances that the pause would be brief, the network has been experiencing disruptions and delays since Grinta was ￰6￱ to logs from StarkNet’s status page, users reported several incidents of stutters throughout the evening of Monday and the morning of September ￰7￱ up concerning Grinta ⚠️ Grinta (aka Starknet v0.14.0) is a major milestone for Starknet’s architecture, advancing both decentralization and ￰8￱ this upgrade drastically changes Starknet’s core architecture (decentralized sequencer, fee market, mempool…)… — Starknet (@Starknet) August 31, 2025 “Grinta drastically changes StarkNet’s core architecture,” the network’s Sunday post read, mentioning changes to the decentralized sequencer, fee market, and mempool.

“During this window, transactions will not be received on Mainnet to avoid incorrect processing once the network is back to normal.” Today, at around 2:28 AM UTC, StarkNet issued a “slow block creation alert” on its network status website, resolving it before posting another update an hour ￰9￱ block production was again taking longer than expected, and within the same timeframe, the team confirmed investigations were ￰10￱ hours after the first alert, gateways stopped receiving transactions, triggering an “idle gateways alert.” Though resolved minutes later, the problem recurred at 5:18 and again at 5:28 AM when StarkNet confirmed that transactions were not being ￰11￱ disruptions continued well into Tuesday daylight hours, with another block creation slowdown reported at 7:08 AM, followed by further issues at 7:18 ￰12￱ incidents were marked as resolved, but the network is reportedly still under close ￰13￱ later announced the outage lasted longer than planned and said engineers were working to restore full ￰14￱ team reiterated that service stability was a priority as the Grinta update continued to be ￰15￱ launch Grinta to improve decentralization The Grinta upgrade could push StarkNet toward decentralization, but much of the network is still under StarkWare’s centralized ￰16￱ operations, which handle the ordering of transactions, are still managed by the ￰17￱ to StarkNet’s published roadmap, the long-term goal is to distribute block validation and production among several independent ￰18￱ eventual rollout of decentralized sequencing and proving mechanisms would align the protocol with public blockchain standards, where security is maintained through community-driven consensus.

Meanwhile, the outage comes just two weeks after StarkNet announced plans to integrate Bitcoin staking into its ecosystem under proposal ￰19￱ community approved the developments with a 93.6% vote ￰20￱ integration will allow wrapped Bitcoin assets such as WBTC, LBTC, tBTC, and SolvBTC to participate in the network’s staking ￰21￱ consensus model will give Bitcoin a 25% weighting in staking power, while StarkNet’s native token STRK will hold the remaining 75%.
