ChainCatcher news, according to Protos, Bitcoin developers recently disclosed details of a high-risk software vulnerability named CVE-2024-35202. According to senior core developers, over 13% of home and commercial computers executing Bitcoin rules globally are affected by a remote shutdown vulnerability.The vulnerability affects nodes running versions of Bitcoin Core prior to 25.0, allowing attackers to crash nodes by manipulating block transaction messages. The vulnerability originates from Core's compact block protocol, which uses shortened transaction identifiers to reduce internet bandwidth usage. Attackers can trigger conflicts in these identifiers, causing nodes to request complete blocks. While requesting complete, untruncated blocks is a security precaution, versions of the software prior to 25.0 have flaws in the logic for handling subsequent blocktxn messages.In short, nodes can be forced into an invalid state by manipulating logic gates, leading to a complete crash. Although there is no economic incentive for ordinary attackers, developers strongly recommend that node operators update to the latest version. The credit for discovering and disclosing this vulnerability goes to Niklas Gögge, and Bitcoin Core 25.0 has resolved this issue.

ChainCatcher message, the Unichain white paper states that to become a validator in UVN, node operators must stake UNI tokens on the Ethereum mainnet. The staking status is tracked in Unichain's smart contract, which receives notifications of staking and withdrawal operations through a native bridge. Unichain's blocks are divided into fixed-length Epochs. At the beginning of each Epoch, the current staked balance is snapshot, and Unichain chain fees are collected and calculated for the reward value of each staked token.Participants can also stake and vote for validators, thereby increasing the staking weight of that validator. A limited number of validators with the highest staking weight will be considered the active set and will be eligible to publish proofs and receive the designated rewards for that Epoch.

ChainCatcher news, according to ACCESSWIRE, the Ethereum Layer2 network Metis plans to launch a community selection process for its first batch of external sequencer node operators, initiating governance roles for distributed network ownership and partial withdrawals for sequencer node operators.Metis introduces a decentralized sequencer node pool, allowing anyone to join and have governance rights over the network. Node operators will also receive a share of the revenue, involving the sorting of rewards and fees. For the first batch of external sequencer node operators, the community can start voting from June 24 to June 28.

According to ChainCatcher, as reported by Cointelegraph, Louisiana has amended its legislation to prohibit the use of Central Bank Digital Currencies (CBDCs) and set rules for miners and node operators. The revised law will take effect in August 2024.These amendments are referred to as the "Blockchain Fundamental Law," which prohibits Louisiana from participating in testing, accepting, or requiring the use of CBDCs for payments. However, other digital currencies are not included in the legal prohibition. The bill states, "No regulatory agency shall participate in the Federal Reserve's Central Bank Digital Currency testing."Louisiana has also implemented strict controls on foreign-owned digital asset mining companies. The state's legislation prohibits foreign entities from acquiring or maintaining any ownership interest in digital asset mining operations within Louisiana.Starting from August 1, 2024, foreign-controlled companies currently engaged in digital asset mining in Louisiana will have one year to completely divest their interests. The law imposes significant penalties for non-compliance, with fines up to $1 million or 25% of the foreign entity's ownership interest in the mining operation.

In the coming two weeks, ARPA will gradually disclose its operator partners.

According to ChainCatcher, citing informed sources from CoinDesk, over 30 validators were kicked out of the Solana Foundation's delegation program last weekend. Although they remain validators on the network, they are no longer eligible to receive rewards for validating transactions on the Solana blockchain. Another source stated that many of the operators are Russian. In total, 32 operators were removed, who collectively held 1.5 million SOL, accounting for about 0.5% of the staked amount in the program.ChainCatcher previously reported that, according to The Block, the Solana Foundation announced that it had removed a group of validator operators from the delegation program due to their involvement in "sandwich" attacks on Solana users.
