The Ethereum Foundation disclosed the results of a recent interoperability meeting held by core developers in the Svalbard archipelago of Norway and updated the key technical progress for the next phase upgrade, Glamsterdam. During the meeting, multiple client teams collaborated on network scalability and execution layer optimization, making progress in several directions. Developers confirmed that based on the comprehensive results of ePBS, BAL optimization, and the EIP-8037 repricing mechanism, a consensus on the "trusted path" after Glamsterdam has been reached.In terms of the execution layer, ePBS (External Proposer Separation Architecture) has been stably running in the multi-client Glamsterdam-devnet, and the external block builder process has completed end-to-end testing, covering almost all client implementations. Meanwhile, EIP-8037 has been finalized, establishing the fixed cost_per_state_byte model, and complete repricing parameter output has been achieved in bal-devnet-6. The scalability direction Hegotá has also made progress. The FOCIL-related prototype has a runnable implementation, and the scope of account abstraction (AA) requirements has been defined, with the next phase entering the multi-client development network verification stage.Current development focus remains on the final implementation of Glamsterdam while advancing the Hegotá scalability design and subsequent Strawmap route evolution. The development network is online, and functionalities such as FOCIL are expected to continue deepening in the next phase of testing. At the organizational level, this interop meeting also marks the formal initiation of leadership structure adjustments within the Protocol Cluster. The new leaders include Will Corcoran, Kev Wedderburn, and Fredrik. Will Corcoran is responsible for zkVM proof and post-quantum consensus coordination, Kev Wedderburn leads zkEVM development, and Fredrik is in charge of protocol security and the Trillion Dollar Security project.Original Protocol Cluster leadership team members Barnabé Monnot and Tim Beiko will gradually step back from management roles, and Alex Stokes is entering a leave period.

According to market news, LayerZero Labs co-founder and CEO Bryan Pellegrino had a heated debate with security researchers today in the ETHSecurity Community Telegram group. The core controversy includes: since LayerZero Labs can immediately upgrade a default library contract without a time limit to forge messages (similar to the case where rsETH was hacked), the LZ OFT, valued at over $3 billion, is recently at risk of being stolen; researcher Banteg pointed out that mainstream projects like Ethena and EtherFi were still using this default library contract weeks ago, and currently, there is still $178 million worth exposed to risk, with these funds coming from projects that are still using the default library.On-chain data shows that LayerZero Labs multi-signature signers participated in non-multi-signature activities such as meme coin trading, DEX exchanges, and cross-chain bridging, which means that the multi-signature keys in the formal environment were connected to websites, increasing phishing risks. Regarding the multi-signature signers of LayerZero using production environment keys for trading activities, Bryan confirmed that the related transactions were completed by members of the multi-signature team, but denied that it was "meme coin trading," explaining it as "testing PEPE on the LZ OFT token standard," and stated that the involved member has been removed. Bryan also suggested that project parties "directly fix configurations" instead of using default configurations to reduce risks. Banteg subsequently tagged a long list of LayerZero users still using the default library contract, pointing out that these projects should migrate to fixed configurations as soon as possible.

The Chief Information Security Officer of Slow Fog, 23pds, disclosed that a privilege escalation vulnerability named Dirty Frag has been exposed in Linux systems, with complete details and exploit code now public. This vulnerability allows any local low-privilege user to directly obtain root privileges on almost all mainstream Linux distributions. It is classified as a deterministic logic flaw, and the attack does not rely on complex race conditions, resulting in a very high success rate without causing kernel crashes, posing significant danger. Linux users are advised to upgrade their systems promptly.

According to CoinDesk, Solana co-founder Anatoly Yakovenko stated at Consensus Miami 2026 that the major upgrade of the Solana network, "Alpenglow," is expected to be launched this year, possibly as early as next quarter.Yakovenko said that the Alpenglow upgrade aims to bring transaction confirmation speeds close to the physical limit of "light speed," enhancing the network's speed, reliability, and transaction certainty, shifting from Solana's early innovations to a more mature phase focused on performance guarantees and reliability. This is crucial for time-sensitive applications such as financial applications.

According to FinanceFeeds, Alex Thorn, the research director of Galaxy Digital, stated that as advancements in quantum computing hardware accelerate, the Bitcoin community is shifting from decentralized debates to forming a preliminary consensus on quantum threats. The core direction is to gradually introduce post-quantum cryptography (PQC) through soft forks, achieving an upgrade of the address system and long-term security assurance.The report points out that the current Bitcoin signature mechanism, which uses the Elliptic Curve Digital Signature Algorithm, can theoretically be cracked by Shor's algorithm. Approximately 2 million BTC from early p2pkh addresses are at risk because their public keys have been exposed, facing the potential risk of "collecting first and decrypting later." The community tends to promote a "migration window" mechanism to guide users in transferring their assets to new quantum-resistant addresses, and after a multi-year grace period, to implement freezing or destruction of untransferred assets to prevent large-scale market impacts in extreme situations. Additionally, the consensus includes enhancing "cryptographic agility," which allows protocols to switch signature algorithms without interrupting the network.The current proposal leans towards a dual-signature mechanism that uses ECDSA and PQC (such as Dilithium) in parallel, ensuring security redundancy while facilitating a smooth transition. Analysts believe that this approach transforms the quantum threat from a "black swan event" into a manageable technological upgrade, helping to solidify Bitcoin's security foundation as a long-term store of value asset.

The Zcash Foundation officially announced the release of Zebra version 4.4.0. This update fixes multiple consensus-level critical security vulnerabilities and strongly recommends that all node operators upgrade immediately. This includes a denial-of-service vulnerability that can cause new blocks to stop being discovered permanently, consensus divergences caused by errors in block signature operation (sigops) counting, anomalies in the processing of transparent transaction signature hashes, and risks of memory allocation amplification attacks.The Zcash Foundation stated that some of these vulnerabilities could cause Zebra nodes to accept blocks that are rejected by zcashd, leading to chain forks. If not updated in a timely manner, nodes may face risks such as interruption in block discovery, consensus forks, and resource consumption amplification, and there are currently no alternative mitigation solutions.

Syndicate has released an update regarding the recent security incident, stating that the leakage of private keys led to the malicious upgrade of bridging contracts on two chains, resulting in the theft of approximately 18.5 million SYND (about $330,000) and around $50,000 in customer tokens. Affected users will receive full compensation, and SYND holders will receive additional compensation.The attack involved multi-stage reconnaissance, infrastructure mapping, vulnerability exploitation development, and precise timing, ruling out the possibility of insider involvement. The root cause of the vulnerability was the storage of private keys in a password manager, and the upgrade process did not utilize multi-signature or hardware signing. Syndicate is strengthening security measures, including adding an encryption layer outside the password manager and implementing multi-signature or hardware signing for the upgrade path.
