Core Insights - Starknet, an Ethereum layer-2 system utilizing zero-knowledge rollups, faced a mainnet outage lasting over two hours, raising concerns about its operational stability as it approaches 2026 [1][2]. Group 1: Outage Details - The outage halted block production for just over two hours, preventing users from submitting or finalizing transactions [2]. - Following the incident, block production resumed shortly after the issue was publicly acknowledged, with new blocks appearing minutes later [4]. Group 2: Network Performance Metrics - Starknet has processed over 264 million transactions since its launch and supports over 56,000 active accounts, with average transaction fees below one cent [3]. - The total value locked in Starknet is approximately $840 million, indicating significant user engagement despite the recent outage [3]. Group 3: Impact on Decentralized Finance - The outage interrupted Starknet's ambitions to serve as a bridge for Bitcoin-related decentralized finance (BTCFi) within the Ethereum ecosystem [5]. - This incident follows a challenging year for Starknet, including a severe outage in September 2025 after a major upgrade, which lasted around nine hours and required users to resubmit transactions [6][5]. Group 4: Underlying Issues - A post-mortem of the September outage identified that inconsistent views of Ethereum among different sequencers, due to RPC provider issues, disrupted block proposals [7].
