The Zcash developers have completed the consensus rule changes for the Ironwood upgrade and plan to activate this upgrade in July. This upgrade will introduce a new privacy transaction pool based on the Orchard protocol to replace the old Orchard pool, and adjustments will be made to ensure that the circulating supply of ZEC remains constrained.According to the developers' plan, Ironwood will introduce a "flag" mechanism between the old and new Orchard pools, restricting the old pool from receiving new transactions while allowing for change generation as a privacy protection measure. After the upgrade is activated, the old Orchard pool will be prohibited from receiving new deposits, and wallets will route new transactions to the new pool.The developers stated that this design combines the existing turnstile mechanism to ensure that the circulating supply of ZEC cannot be infinitely minted and allows users to migrate their funds to the new pool to reduce potential risks.

AMIKO announced the completion of the full-platform Agent runtime upgrade, with the underlying platform migrated to the self-developed open-source architecture OpenHermit. According to information from the project team, existing users have completed the system transition, and new users will directly operate on the OpenHermit architecture after registration. Meanwhile, the AMIKO ecosystem development segment has officially entered the open phase.AMIKO is an identity and social infrastructure aimed at the AI Agent era, focusing on four aspects: identity, productivity, social interaction, and economy, with the goal of enabling users to have AI Twins, Companions, Assistants, and Experts that can represent them in actions, communication, and collaboration. OpenHermit is AMIKO's self-developed open-source Agent runtime, designed for large-scale production-level deployment scenarios, supporting stable hosting and low-cost continuous operation of a large number of Agents.During the internal testing phase, OpenHermit has gained discussions and code contributions within the global developer community, and the related code repository has been opened on GitHub. Documentation and quick start guides can be viewed at openhermit.ai.This upgrade is also seen as a product landing point for AMIKO's recent strategic actions. Previously, AMIKO received strategic investment from the American technology investment firm High Ridge Holdings and reached a strategic equity partnership and comprehensive ecological cooperation with Feixiaohao.With the completion of the underlying architecture upgrade, independent developers and professional teams can develop and deploy products and services within the platform ecosystem based on AMIKO's infrastructure covering identity, productivity, social interaction, and economy. AMIKO stated that its goal is to become a universal Agent infrastructure platform in the AI-native era, allowing the flow of identity, productivity, social interaction, and economy to occur naturally between users and Agents.

According to CoinDesk, in April this year, the cross-chain bridge KelpDAO based on LayerZero suffered an attack of $292 million, triggering a deposit run of up to $8.45 billion in the DeFi lending protocol Aave within 48 hours. In response to external doubts about the protocol's risk control capabilities, Aave founder and CEO Stani Kulechov stated that this incident precisely proves Aave's "resilience."Kulechov stated at the Proof of Talk conference in Paris that Aave V3 has withstood multiple market cycles and remains stable even in extreme market conditions. He believes that recent DeFi security incidents mainly stem from third-party infrastructure rather than vulnerabilities in the protocol's own smart contracts.However, according to risk analysis firm LlamaRisk, the attacker exploited a vulnerability in KelpDAO to mint worthless collateral and deposited it into Aave, subsequently withdrawing real wETH, resulting in approximately $123.7 million in bad debt for Aave V3. To address the crisis, Aave DAO urgently allocated 25,000 ETH, and Kulechov personally injected an additional 5,000 ETH, with a total rescue scale of about $300 million.In response to the exposed systemic risks, Aave is planning to restructure its risk management framework through the V4 upgrade. The new version will adopt a modular "Hub-and-Spoke" design, replacing the traditional liquidity pool model, allowing the protocol to implement independent risk pricing for different collateral types and freeze specific collateral assets before risk spreads, thereby reducing the likelihood of chain reactions triggered by cross-chain bridge failures.

Four.meme announced the launch of OpenFour, planning to upgrade from a single Meme coin Launchpad platform to an open modular token issuance infrastructure on the BNB Chain.

According to The Block, the Sui Foundation released an incident analysis report on the recent three interruptions of the mainnet, attributing the three network outages that occurred last Thursday and Friday to two independent vulnerabilities introduced by the v1.72 version upgrade. The first interruption lasted about six and a half hours, while the second and third occurred on Friday morning and afternoon, respectively.The first two interruptions were caused by the "address balance" feature introduced in v1.72, which exposed flaws in the transaction fee deduction method. When a transaction was canceled due to insufficient funds, the network would still spend those funds, resulting in a negative balance that caused the validation node reconciliation process to crash. The foundation acknowledged that the temporary fix pushed urgently on Thursday carried known interruption risks, and the team accepted this risk to quickly restore on-chain services, which led to another network interruption on Friday morning.The third interruption was triggered by another undisclosed random state vulnerability, occurring when the validation nodes restarted to install the fix patch. Sui stated that user funds were never at risk, that both vulnerabilities have been fixed, and that a mechanism to forcibly terminate stalled epochs has been established. The foundation also mentioned that AI agents with access to its production systems significantly accelerated the diagnostic process.
