The Zcash Foundation released Zebra versions 4.5.3 and 5.0.0 to address a critical soundness vulnerability in the Orchard zero-knowledge proof circuit. Version 4.5.3 temporarily disables Orchard operations via an emergency soft fork, while version 5.0.0 activates NU 6.2, re-enables Orchard using the patched circuit, and permanently closes the vulnerability.
Uniswap founder Hayden Adams posted that he is deeply grateful for the long-standing funding and multifaceted support provided by the Ethereum Foundation (EF), but he specifically clarified that Uniswap was not incubated by the EF; rather, he participated as an external grant recipient with close personal ties to the EF. Previously, EF Chair Aya Miyaguchi and co-founder Vitalik Buterin publicly shared their views on the EF’s future direction. Miyaguchi noted that one reason for proposing the EF’s mission framework at the end of last year was the growing deviation in technical discussions.
Odaily Telegram CEO Pavel Durov stated that the native token of The Open Network (TON) will be renamed to Gram, reverting to its original name as outlined in the project's early whitepaper. TON will remain the name of the blockchain network, while Gram will serve as the name of its native currency.Durov noted that this renaming is the fourth step in the seven-step "Make TON Great Again" plan, and the entire transition is expected to take approximately three weeks. The remaining three initiatives have yet to be disclosed.Previously announced steps include the TON network upgrade, increased transaction settlement speed, significantly reduced fees, and Telegram's plan to replace the TON Foundation as the ecosystem's primary manager and largest validator.
Odaily news: The Zcash Foundation has announced the release of Zebra 4.5.1 version update to fix a consensus-critical security vulnerability and strongly recommends that all node operators upgrade immediately. The vulnerability, identified as GHSA-2prc-cj5x-4443, involves a sigops (signature operation count) counting error in P2SH transactions, which could lead to potential consensus fork risks. This fix corrects an incomplete patch in the previously released 4.5.0 version, which was just released yesterday.The Zcash development team stated that the issue stems from discrepancies in sigop counting logic between different implementations, which could cause nodes to produce different results when verifying transactions, thereby affecting consensus consistency on the chain. The fix resolves this by reverting and adjusting the Rust implementation logic to ensure alignment with the expected protocol behavior.The Zcash Foundation emphasized that there is currently no workaround for this issue, and upgrading to 4.5.1 is the only method to ensure nodes remain on the correct chain and avoid potential fork risks.
According to The Block, the Sui Foundation released an incident report on May 31, disclosing three consecutive outages on its mainnet from May 29 to 30—each traced back to two independent bugs introduced in the v1.72 upgrade. The first two outages were caused by a gas fee calculation error stemming from the newly launched “address balance” feature: funds were deducted even when transactions were canceled, resulting in negative account balances and subsequent validator node crashes. The third outage was triggered by a latent vulnerability in the random number generator during node restarts, preventing the network’s epoch from closing normally. The Sui Foundation stated that all known issues have now been resolved; user funds remained unaffected throughout the incidents, and no settled transactions were rolled back. The Foundation plans to further enhance its fault-tolerance mechanisms to ensure future similar bugs impact only individual transactions—not the entire network.
According to The Block, the Cardano Foundation confirmed that the Cardano Summit 2026 will not be held this year, as the on-chain treasury funding proposal failed to reach the required supermajority threshold of 66.67%. The revised proposal sought a grant of 7.8 million ADA—approximately $2 million—but ultimately secured only 65.21% support from DReps’ staked voting power and was therefore rejected. The summit had been scheduled to take place in Singapore on October 5–6. Separately, EMURGO’s sponsorship proposal for TOKEN2049 has been approved.
: The Zcash Foundation has released version 4.5.0 of its node client, Zebra. This update includes multiple security fixes, addressing a critical consensus vulnerability and several high-severity Denial of Service (DoS) issues. All node operators are strongly urged to upgrade immediately.Key fixes in this release include a sigop counting error in P2SH script parsing (which could cause a consensus fork with zcashd), a logic flaw in NU5 block validation caching, a crash risk related to transparent address balance overflow, along with multiple crash and resource exhaustion vulnerabilities in RPC interfaces and mempool processing. The Foundation stated that some vulnerabilities could be exploited by malicious nodes, leading to node stalls, restart loops, or even permanent stoppage.Additionally, this version adds support for ZIP-213 (enabling shielded coinbase outputs to Sapling) and optimizes network performance and security boundaries. This includes limiting resource allocation during the pre-handshake phase, fixing risks related to multi-threaded queue abuse, and enhancing the misbehavior scoring mechanism.The Zcash Foundation stated that this update addresses over 80 security reports from the ZCG Vulnerability Disclosure Program (spanning April to May 2026), covering multiple layers including consensus security, memory management, RPC processing, and the P2P network attack surface. Officials emphasized that there is no alternative to this upgrade; upgrading is the only way to ensure nodes do not experience a chain split and remain secure.
According to PR Newswire, the Open Transaction Layer (OTL) officially launched on May 28 as an open industry initiative aimed at establishing a unified transaction coordination standard for on-chain finance. OTL defines shared protocols among institutions, non-custodial wallets, and AI agents for identity verification, messaging, and transaction coordination—covering the entire transaction lifecycle, including discovery, compliance, and settlement. The founding alliance comprises over 25 members, including leading financial institutions, payment service providers, and blockchain foundations such as Fireblocks, Checkout.com, Cross River Bank, MetaMask, Robinhood, Securitize, Wintermute, Solana Foundation, and Polygon. OTL’s technical specifications are built upon mature standards including W3C Decentralized Identifiers (DIDs) and ISO 20022, and adopt a modular five-layer architecture covering Identity, Session, Transport, Messaging, and Application layers. The specifications have been published under an open-source license at otl.network, and the alliance is also open to additional institutional participation.
the US Depository Trust and Clearing Corporation (DTCC) and the Stellar Development Foundation have announced a partnership to deploy DTC custody asset tokenization services on the Stellar network, with the associated assets expected to go live in the first half of 2027.DTCC received a no-action letter from the US SEC in December 2025, authorizing it to conduct real-world asset tokenization business. The two parties will focus on the on-chain conversion of highly liquid assets, including Russell 1000 constituent stocks, major index ETFs, US Treasuries, and various bonds. This collaboration leverages the Stellar network to establish a compliant on-chain channel, representing a significant step in the integration of traditional financial infrastructure with blockchain technology and will further expand the application scenarios for real-world asset tokenization.
According to Bitcoin Laws, New Hampshire’s “Blockchain Foundation” bill HB 639 advanced today, with the state House and Senate reaching agreement on a compromise version of the bill—after each chamber had previously passed different versions. As disclosed, the bill aims to protect several related “rights,” including the right to pay with cryptocurrency, run nodes, and conduct mining activities.
According to The Defiant, the Ethereum Foundation’s Kohaku Initiative has released an SDK for integrating privacy protocols into Ethereum wallets. A functional 4337 mempool relay supporting private transactions is now available in version v0.0.1-alpha.21 of the kohaku-eth/railgun integration. This SDK aims to integrate shielded-pool protocols—such as Railgun, Tornado Cash, and Privacy Pools—directly into wallet interfaces, reducing reliance on centralized relay infrastructure. Kohaku has also demonstrated a CLI-based wallet and is advancing integration with production-grade wallets like Ambire, while simultaneously developing post-quantum accounts, multisig support, and hardware wallet compatibility.
Vitalik Buterin stated that the Ethereum Foundation (EF) is not the “center of Ethereum,” but rather “a node within the ecosystem,” and is currently transitioning toward a smaller, more opinionated, and more sustainability-focused organizational structure. He explained that the Foundation will prioritize allocating its limited resources to work essential for Ethereum’s viability as a censorship-resistant, control-resistant, open, private, and secure system—work that would be unlikely to happen without the Foundation’s involvement—while also reducing ETH sales. Vitalik further noted that Ethereum should not pursue only maximum throughput and low latency, but should instead aim to be “impressive” in areas such as formal verification, chain availability consensus, and reducing reliance on intermediaries. He emphasized that the Foundation’s new structure is expected to gradually stabilize over the coming months.
Blockchain researcher and investor William Mougayar has come to the defense of the Ethereum Foundation, arguing that the public has long misunderstood its role and that it is "executing its mission precisely."Mougayar stated that ETH, the Ethereum network, and the Ethereum Foundation itself are three distinct entities: ETH is an asset, Ethereum is a shared computing infrastructure, and the Foundation is a non-profit organization responsible for driving protocol development, with one of its goals being to "gradually make the founder irrelevant."He pointed out that many critics want the Foundation to take on responsibilities like marketing ETH or attracting institutional capital, which would be akin to "expecting the IETF to run a Super Bowl ad for TCP/IP." He emphasized that the Ethereum Foundation is currently on a "subtraction path," strengthening the network by advancing protocol upgrades, funding fundamental research, and reducing its own centralized influence.Recently, the Ethereum Foundation has faced community criticism for selling ETH, unstaking, and a lack of public communication. Data shows that the Foundation has completed its third OTC sale this month to BitMine Immersion Technologies, cumulatively selling approximately 25,000 ETH worth about $47 million. Additionally, the Foundation has recently unstaked over 38,000 ETH in total, with a combined value nearing $90 million. (Cointelegraph)

The Zcash Foundation released its Q1 2026 report, disclosing total liquid assets of approximately $36.7 million, including roughly $12.11 million in cash, 506,556 USDC, 85,412 ZEC (valued at ~$21.2 million), 41.8 BTC (valued at ~$2.85 million), and 12.02 ETH (valued at ~$25,000). The Zcash Foundation added that, although the first quarter of this year saw personnel changes within the Electric Coin Company’s development team and governance-related disputes, network operations remained unaffected, with transactions and block production continuing normally. On the regulatory front, the U.S. Securities and Exchange Commission (SEC) has concluded its investigation without taking any enforcement action, thereby resolving long-standing regulatory uncertainty.
Adam Hollander, Chief Marketing Officer of OpenSea, stated that the next cycle of NFTs could look very different from the speculative frenzy of 2022, which saw over $1.6 billion in trading volume. Speaking to The Block at Consensus Miami, Hollander noted that it "makes perfect sense" to put assets like collectible cards, luxury watches, and digital tickets on-chain for trading, and that these could be the core drivers of a new wave of NFTs.Adam Hollander emphasized that although avatar-based NFTs like Bored Apes and CryptoPunks have experienced a value crash, NFT technology still has potential to prove ownership of both digital and physical assets. He believes the previous NFT boom relied too heavily on speculation, with buyers treating NFTs more like a digital casino rather than focusing on their technology and real-world value. The future application of NFTs will be driven by actual demand for collectibles, in-game items, AI tools, and more. The development of artificial intelligence will also lower the barrier to creating digital art, animations, and games, thereby accelerating NFT adoption.Regarding platform development, OpenSea is working to build an ecosystem that allows users to manage all their crypto assets and NFTs across different wallets and chains, while optimizing the user experience. This includes simplifying the onboarding process, supporting Apple Pay-like fiat payments, and displaying NFT prices in US dollars. When asked about the delay in launching the much-anticipated SEA token, Hollander stated that the decision lies with the OpenSea Foundation, and he personally has no further information on the timeline. He emphasized that if the token were merely an "airdrop meme coin," it would not create value for users. (The Block)
