According to The Block, Ethereum ecosystem core contributor Nethermind announced that after a "comprehensive review," it will exit the LayerZero decentralized validation network (DVN) business and migrate its cross-chain infrastructure to the Chainlink network. Nethermind stated that it has ceased operations of LayerZero's DVN and joined the Chainlink network as a node operator and strategic technology provider.In the future, Nethermind will provide engineering tools, infrastructure services, and integration support for blockchain application developers. It is reported that this shift occurred after the LayerZero ecosystem experienced a security incident. In April of this year, the rsETH cross-chain bridge of Kelp DAO was attacked, resulting in a loss of approximately 116,500 rsETH, valued at about $292 million at the time. Following this incident, several companies have begun to shift their cross-chain operations from LayerZero to Chainlink. However, Nethermind did not explicitly state whether this migration is directly related to the Kelp DAO incident, nor did it disclose any specific technical issues with LayerZero or changes in commercial terms between the two parties.

The official urges users to upgrade as soon as possible, while noting that the Windows version of Decrediton has not yet been released and is expected to be launched the following day.

Sei announced the launch of the Eidos upgrade, which involves a comprehensive reconstruction of the on-chain storage layer. Eidos is one of the three parts of the Sei Giga upgrade trilogy, following the consensus layer Autobahn and the execution layer Ares, which have been progressively advanced. Eidos is responsible for addressing the most critical storage bottleneck in blockchain scalability.Core changes include: replacing the traditional Merkle tree with FlatKV and LtHash, allowing state updates to shift from chain-based hash recalculation to constant time operations; migrating EVM state to an independent database, with historical data moved to off-chain archives, and nodes retaining only the content necessary for real-time operations.Sei's long-term goal for the Giga upgrade is 200,000 TPS, and Eidos is a key underlying support for achieving this goal. This upgrade represents an update to the technical roadmap, and the specific implementation effects will need to be validated in the future. Node operators can configure migration according to Sei's official documentation.

The attention economy platform Kaito AI launched the browser extension Kaito Pulse on August 18, which can directly integrate users' public holdings and other off-chain activities on platforms like Polymarket and Hyperliquid into the X timeline, and synchronously introduce the attention metric Aura to measure the attention signals generated by users' statements and actual behaviors. Users can accumulate Aura by installing the extension, using Yaps to receive initial Aura, verifying transactions, or engaging in creator activities.Subsequently, well-known analyst @0x_ultra released a source code analysis stating that the extension has multiple data collection behaviors, including generating a unique device fingerprint through GPU rendering, device model, and audio tests, and associating it with the X account; recording user behaviors such as scrolling duration, clicks, searches, bookmarks, etc., during X sessions, and sending heartbeat packets every 30 seconds; reading subscription plans and usage for ChatGPT and Claude during verification, as well as wallet balances, holdings, profits and losses, and deposit/withdrawal records on platforms like Binance. The extension only allows communication with the Kaito domain, and the ZKTLS part is based on the open-source project Primus branch. Kaito officials have not yet responded to this.

The Wyoming Stablecoin Committee has migrated its issued Frontier Stable Token (FRNT) from LayerZero to Chainlink's cross-chain interoperability protocol CCIP, and will completely discontinue the LayerZero token implementation after completing a comprehensive security review. CCIP will serve as the sole cross-chain infrastructure for FRNT under a multi-year contract. This is the first time a U.S. government entity has publicly changed blockchain infrastructure for security reasons, and FRNT is currently the only stablecoin issued by a U.S. public institution, fully backed by fiat reserves, with reserve earnings used to support the state's school foundation projects. The token has been deployed on chains such as Ethereum, Base, and Avalanche, with a current market cap of less than $1 million.This decision was announced four months after the Kelp DAO bridge based on LayerZero was attacked, resulting in the theft of approximately 116,500 rsETH (worth about $292 million at the time), an incident that triggered a wave of industry security reviews and migrations. To date, nearly $15 billion in related assets have migrated from LayerZero to Chainlink, with early movers including Kelp, Solv Protocol, Re, and Kraken. Subsequently, BitGo chose CCIP and completed a migration of approximately $7.7 billion in wrapped Bitcoin, bringing the total to the current level. According to a case study by LayerZero in January of this year, Wyoming had previously operated its own decentralized validation network and controlled validation and compliance functions.

Ethereum developer kevaundray submitted the EIP-12188 proposal, suggesting to shorten the consensus layer block retention window to reduce storage pressure on nodes. The proposal is currently in the public review stage and has received support from some Ethereum client developers.Developer DApplion expressed support for the proposal, while Lighthouse client contributor michaelsproul believes that this adjustment will not significantly impact Lighthouse's operation. The proposal points out that as the demand for Ethereum historical data changes, reducing the retention time for historical blocks in the consensus layer can optimize node resource usage.It was mentioned in the discussion that historical data pruning in the execution layer may affect some long-running nodes' ability to provide old block data, but developers believe this will not threaten network security or the normal operation of nodes. Currently, EIP-12188 has not yet been merged and still requires further review and community discussion.

According to official news, the credit delegation layer project Twyne announced the completion of its seed round financing, which was co-led by Cyber Fund and Ethereal Ventures. Twyne aims to build a Credit Delegation Layer that connects idle credit in the lending market with parties in need of credit, addressing the issue of collateral depositors' credit being locked and half of the market's credit being idle while the other half urgently needs credit.Twyne stated that in the current lending market, credit often remains with the party depositing collateral, leading to a mismatch between supply and demand. The project will promote the flow and efficient allocation of credit through the credit delegation layer.
