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.

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.

ChainCatcher news, Lido announced that its Simple DVT (Distributed Validator Technology) module has been deployed on the Ethereum mainnet. This Simple DVT module (sDVTm) is the second mainnet module of the Lido protocol, designed to leverage the technology provided by Obol and SSV Network to offer independent and community stakers the opportunity to participate in running validators using Lido. After intensive testing on the testnet, all aggregated performance metrics exceeded the minimum targets. Additionally, Lido mentioned that a performance report will be submitted to the DAO after the first Obol network cluster validator has been active for 30 days, paving the way for future network expansion. Meanwhile, the third SSV network testnet is nearing completion and has also exceeded all minimum performance standards. Lido plans to release a comprehensive review after the testnet concludes and submit a proposal regarding the entry of SSV network participants into the mainnet.Lido stated that with the launch of the Simple DVT module, it is expected that over 250 new node operators will join the Lido protocol in the coming months, which will increase Lido's node operator base by 676%. This marks the beginning of the initial implementation phase of the Simple DVT module, with more Obol-based clusters expected to join the mainnet in the coming months, and a DAO proposal is anticipated to be submitted to incorporate SSV network participants into the mainnet.

ChainCatcher news, Lido officials stated that in the past 24 hours, contributors to Lido DAO were informed of a platform vulnerability affecting the active node operator (InfStones) of Lido on Ethereum, which had been exploited at some point over the past few months. This vulnerability was disclosed to InfStones by security researchers dWallet Labs in July 2023. The node operator announced that the vulnerability has been resolved.The vulnerability involved the potential exposure of root-level access to 25 validator servers to external attackers who may not be related to the Lido protocol, which could include critical materials. It is currently unclear whether contributors included servers and/or keys related to Lido validators within the scope of the affected systems.Contributors to Lido DAO have drawn the following conclusions regarding the aforementioned vulnerability: there is no indication that any keys were leaked due to this vulnerability; however, as a precaution, InfStones voluntarily withdrew all validators and rotated to new keys, awaiting DAO voting. All ETH from the withdrawn validators will flow back to the Lido protocol through the withdrawal process and will subsequently be re-staked into available keys in the buffer.
