Linea says some Yield Boost validators will exit after MetaMask Staking incident

Linea said some validators supporting its Yield Boost vault are exiting for security reasons following the MetaMask Staking incident. The project said vault funds and control remain unaffected, but net staking yield used for ecosystem incentives will temporarily decline while the validators are withdrawn and replaced. The team said it is closely monitoring the situation. The update follows an earlier statement from MetaMask on Oct. 1. At the time, MetaMask said it was responding to a security incident affecting part of its infrastructure. The company also said it was coordinating with customers, partners, and security advisers, and was proactively exiting affected validators involved in non-custodial staking operations.

Celestia says Fibre hit 3.07 Tb/s in benchmark with 120 validators

Celestia said its data availability system, Fibre, reached sustained throughput of 3.07 terabits per second in an end-to-end benchmark involving 120 validators. The test covered the full pipeline, including data encoding, distribution, storage, validator signatures, and on-chain commitment submission. The team said the result came from an experimental benchmark and should not be read as evidence that the Celestia mainnet is currently handling real user traffic at the same rate. Based on the figure disclosed, the throughput would be enough to support a theoretical capacity of nearly 2 billion transactions per second. Celestia added that performance in a live production setting still needs to be validated. The update was reported by Techub, citing NewsBTC.

Cosmos Hub’s 25-Hour Halt Shows Where Blockchain Consensus Actually Breaks

Cosmos Hub stopped producing blocks at height 33,086,740 on Sept. 22 after validators representing more than one-third of total voting power went offline, and the network resumed roughly a day later after a coordinated restart. The article argues that the incident was not a direct attack on Cosmos Hub itself. Instead, the chain was pulled into the fallout from a governance exploit on Neutron, where an approved proposal let an attacker use chain-level privileges to change contract administrators and move assets. According to a Cosmos Labs post-mortem cited in the piece, about 1.7 million ATOM was bridged into Cosmos Hub before Neutron stopped, prompting some Hub validators to halt nodes to prevent further movement. Recovery came through a Gaia v28.3.0 patch and a one-time state change that moved 1,227,121 ATOM from the attacker’s address into a 4-of-6 multisig managed by Nansen, Keplr, Enigma, Silknodes, Kiln, and Polkachu. Beyond the incident itself, the article uses Bitcoin, Ethereum, and Solana as comparisons to explain why decentralization does not mean a chain can never stop, and why private key control is not the same thing as control over consensus.

MetaMask exits 17,000 Ethereum validators after reward payments were diverted

MetaMask said it has proactively begun exiting 17,000 affected Ethereum validators after a security incident tied to part of its infrastructure, covering more than 523,000 staked ETH valued in the report at about $1.4 billion. The company said there was no immediate threat to MetaMask wallets and that the issue was limited to its non-custodial staking operations. Security researcher 0xKaden said block rewards from 18 MetaMask validators were sent to the wrong fee recipient, an address funded by Tornado Cash, with the total diverted rewards reported at less than $1,000. On-chain analyst Emmett Gallic also flagged a 133,300 ETH transfer from wallets labeled Lubin/ConSensys a few hours before MetaMask’s statement, though the report said there is no indication that transfer was suspicious. The validator exits pushed Ethereum’s staking exit queue to its highest level of the year, rising from roughly 200,000 ETH on Wednesday to more than 700,000 ETH on Thursday, while the wait time increased from three and a half days to nearly two weeks. Lido said it expects the ETH to be deposited again after an exit, withdrawal, and re-entry cycle that could take up to 45 days because of the extended entry queue.

About 523,000 ETH tied to voluntary validator exits as MetaMask incident points to altered reward address

Monitoring data cited by Kaden suggests the earlier security incident involving MetaMask validators may be linked to a change in the block reward recipient address. According to Kaden, 19 MetaMask validators received block rewards, but rewards from 18 of them were not sent to the correct fee recipient address. Instead, the funds were routed to an address identified as being funded by Tornado Cash, listed as 0x98B9...24A3. Kaden said the attacker appears to have stolen about 0.36 ETH in rewards. At this stage, Kaden said there is no sign that the attacker had the ability to withdraw staked ETH. Separate data also shows that about 17,000 validators have voluntarily exited, involving roughly 523,000 ETH. Kaden added that it remains unclear whether the attacker was able to modify all fee recipient addresses. The report focuses on the reward flow tied to validators and does not state that staked principal was extracted.

Kaden says attacker in MetaMask security incident diverted about 0.36 ETH in validator rewards

On-chain researcher Kaden said a MetaMask security incident appears to have redirected validator rewards away from their intended destination. According to Kaden, 18 out of 19 block reward payments earned by validators were not sent to the designated fee recipient. Instead, the funds were routed to an address backed by Tornado Cash funds. Kaden estimated that the attacker ultimately obtained about 0.36 ETH from those rewards. Kaden also said MetaMask has proactively exited roughly 17,000 validators tied to about 523,000 ETH. The remarks were published in a post linked in the source material. No additional details beyond those statements were provided in the input.

Osmosis says maintenance phase is ending and active development will resume with three OSMO proposals

Osmosis, a decentralized exchange protocol in the Cosmos ecosystem, said its maintenance mode over the past several months is about to end and active development will restart. The team said its first step will be to simplify the core product, with work focused on streamlining tokenomics, narrowing treasury deployment, and making the network faster to act when needed. As part of that plan, Osmosis outlined three OSMO changes that will all be submitted to on-chain governance. The proposals include cutting inflation further to reduce newly issued OSMO entering circulation, ending the flow of newly minted OSMO into the community pool, and shifting the network to rely more on real revenue. The team also proposed burning most of the OSMO held in the community pool, along with OSMO previously distributed from that pool, and limiting treasury liquidity provision to core liquidity pools, with a full list to be released before the changes take effect. In addition, Osmosis said it plans to reduce the active validator set to 30, arguing that a smaller set would help with security incident response and chain upgrade coordination while fitting a lower-inflation model.

ether.fi says WEETH has no exposure to Ethereum node operator security incident

ether.fi said on X that it is aware of an earlier security incident involving an Ethereum node operator, but added that WEETH has no exposure to the issue and will not be affected. The protocol said all funds remain safe. Earlier the same day, MetaMask said it was handling a security incident affecting part of its infrastructure. According to MetaMask, there is currently no evidence of any direct threat to MetaMask wallets. As a precaution, the company said it is working with customers, partners and security advisers to proactively move affected validators in order to protect the safety of its non-custodial staking business. The statements were cited by ChainCatcher in a market analysis newsflash.
