The outage was the second major network disruption in 2025, with both incidents requiring a block reorganization that rolled back some activity. The team behind Starknet, an Ethereum layer‑2 (L2) scaling network, released a post-mortem report outlining the root cause of the temporary mainnet downtime on Monday. The root cause of the mainnet downtime was a discrepancy in the network state between the blockifier execution layer and the proving layer that checks that the execution layer is processing transactions correctly, according to the report. The Starknet team explained: This incorrect execution never saw L1 finality thanks to Starknet’s proving layer,” the StarkNet team said, highlighting how the proving layer functioned properly by flagging the error and not committing the faulty transactions to the ledger.

Starknet, an Ethereum ZK‑rollup network used for decentralized finance and gaming, is facing mainnet downtime following previous outages in 2025. Starknet, an Ethereum layer‑2 network that uses zero‑knowledge (ZK) rollups, is experiencing fresh mainnet disruption as the project enters 2026. In an X post, the Starknet team said the network was facing downtime and that engineers were “actively investigating the issue and working to restore full functionality as quickly as possible,” without immediately disclosing a root cause. At the time of writing, the network had been experiencing downtime for just over two hours. Starknet is a ZK‑rollup–based layer 2 that batches transactions offchain and posts cryptographic proofs to Ethereum, aiming to deliver higher throughput and lower fees for smart contracts, decentralized finance and gaming applications while inheriting Ethereum’s base‑layer security.

Anchorage Digital has added custody and staking for Starknet’s STRK token, expanding the token's utility for institutional investors in the US. Anchorage Digital, a chartered crypto bank in the United States, has launched custody and staking support for Starknet’s native token, STRK, seeking to address investors’ appetite for yield generation on digital assets. According to a Wednesday announcement, staked STRK currently yields an annual percentage rate (APR) of 7.28%. Anchorage, offering STRK custodian services since January, is expanding the token’s utility. “Anchorage Digital has a long-standing relationship with Starknet and now is opening the door to institutional custody and staking of STRK,” the company said in a statement.

BitcoinOS and Starknet are on the verge of adding smart contract functionality to Bitcoin — with, or without, the controversial OP_CAT fork. BitcoinOS and Starknet arent waiting around for the controversial OP_CAT hard fork to add new functionality to Bitcoin, with both projects devising innovative ways to scale Bitcoin using zero-knowledge (ZK) proofs right now. The projects have both demonstrated it’s possible to verify ZK-proofs on Bitcoins existing mainnet even if Bitcoins ultra-simple scripting language makes it difficult and expensive. This could create genuine Bitcoin L2s that inherit much of its security, and unlock the intriguing possibility of creating programmable tokens on Bitcoin itself. Best known as an Ethereum L2, Starknet wants to use the tech to scale Bitcoin to thousands of transactions per second, up from just 7 TPS today. “The ecosystem in Starknet is very, very enthusiastic about also expanding to Bitcoin,” co-founder Eli Ben-Sasson tells Magazine. BitcoinOS, meanwhile, claims it will s...
