According to CoinDesk, Ethereum researchers have proposed rebuilding the validator deposit contract to support a new cryptographic system and ultimately stop accepting deposits protected by the existing BLS signatures. This proposal targets the deposit contract, aiming to add a switch that prevents the network from accepting the currently relied-upon signature format.Currently, the contract only accepts BLS keys because their exact size is hardcoded, while the new draft allows for different key sizes, with each deposit tagged by the cryptographic system used, where BLS receives a tag of zero, reserving space for future schemes.If the proposal is approved, it will initially operate with BLS deposits, while other schemes can be registered simultaneously. Future decisions may permanently disable new BLS deposits, at which point validators who have staked using BLS keys will not disappear, but new validators will not be able to join using this method. Ethereum will ultimately need to change separately to inform validators how to check new signatures. This is part of the migration for validators, while another part is already in progress—EIP-8141 framework transaction proposals will allow regular Ethereum accounts to change the cryptographic method for approving transactions without changing their address.The urgency stems from research released in March by Google's Quantum AI research department, which outlined five quantum attack paths against Ethereum, putting over $100 billion in assets at potential risk. The Ethereum Foundation is advancing core protocol changes with a target around 2029. Currently, the amount of ETH staked in Ethereum is approximately 42.4 million, valued at about $10.4 billion.

According to GoPlus monitoring, the VSCode extension Solidity Pro has been poisoned, and historical versions have malicious capabilities such as data theft and remote execution.It is recommended that developers immediately check the relevant extensions they have installed and increase their vigilance towards third-party plugins.

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.

Ethereum Foundation researcher Toni Wahrstätter stated that the protocol architecture team hopes to prioritize the advancement of Frame Transactions (EIP-8141) and FOCIL (EIP-7805) in the Hegotá upgrade planned for 2027. Frame Transactions can collaborate with Keyed Nonces and Recent Roots (EIP-8272) and Transaction Assertions (EIP-7906) to allow privacy pools to autonomously pay transaction fees and enable wallets to set execution conditions after transaction submission.FOCIL can provide protocol layer inclusion guarantees for eligible transactions. Currently, FOCIL is the only proposal confirmed for inclusion in Hegotá, while the Frame Transactions-related proposals are among the 66 proposals under evaluation. Other candidate proposals involve transaction pricing, state growth, block access lists, and optional zkEVM proofs on the mainnet. Vitalik Buterin previously proposed enhancing Ethereum's privacy, quantum resistance, and reducing reliance on layer two networks. Hegotá will be launched after Glamsterdam, with developers planning to complete Glamsterdam by the end of 2026.

Bitcoin News posted on the X platform that Bitcoin developers have launched a new visualization tool to explain how entropy works and how to generate randomness for Bitcoin private keys.The tool covers true random number generators (TRNG), pseudo-random number generators (PRNG), rolling dice, and flipping coins.

Ethereum developers proposed a "Tapered Issuance Burn" mechanism, planning to gradually burn a portion of the idealized rewards for validators as the ETH staking ratio increases; when the staking amount approaches 50% of the total supply, the net issuance of ETH will drop to 0%. The author of the proposal stated that the ETH staking ratio exceeded one-third of the total supply in April; if not adjusted, Jerome de Tychey indicated that by January 2028, the staking amount could exceed 70 million, accounting for more than 55% of the supply.Supporters believe that excessive staking may cause small independent validators to lose economic viability first, leading to staking concentration among custodial institutions and large service providers; the plan is proposed to be implemented over 18 months, with an additional approximately 6 months reserved for preparation before potential network upgrades. Aave founder Stani Kulechov stated that once the staking rate exceeds 50%, rewards will drop to 0%, and the uncertainty of returns may weaken institutional staking and DeFi demand. He pointed out that ETH lending strategies may be affected, and this proposal is still in its preliminary stage.

According to The New York Times, Chinese AI models are rapidly gaining popularity in the African developer community due to their low cost, open-source customization, and better handling of local languages, while leading American models like OpenAI and Anthropic are primarily closed-source and paid. Ugandan developer Ernest Mwebaze chose Alibaba's model over Meta or Google products when building a multilingual AI system called Sunflower aimed at local languages, which is now widely used by local farmers to obtain weather and planting information.The report states that similar adoption trends are spreading in countries like Kenya, Nigeria, and Ghana, covering multiple fields such as law, education, and business services. Chinese open-source models (such as DeepSeek and Qianwen) allow for free download and modification, while leading American models are often closed-source and paid, creating significant cost and accessibility differences in middle- and low-income countries. Industry insiders point out that the rapid penetration of Chinese AI in Africa is bringing long-term competitive pressure to American AI giants.

ChianCatcher news, including Ethereum Foundation's Justin Drake and five other researchers and developers, proposed draft EIP-8363 (Tapered Issuance Burn), which aims to significantly reduce validator consensus layer rewards as the ETH staking ratio increases. When the staking amount approaches 60.25 million ETH (approximately 50% of the total supply), the deduction ratio will reach 100% and will be gradually implemented over 18 months.The proposal aims to address the current situation where the staking ratio has exceeded 33%, preventing ETH from being overly concentrated in large custodial institutions and liquid staking protocols, and reducing issuance dilution. Critics, including Aave founder Stani Kulechov and Ether.Fi CEO Mike Silagadze, argue that this move could force independent validators to exit, weaken institutional demand, and impact the DeFi market. The proposal is currently still in the early draft stage and has not yet been approved or included in an upgrade.

Bitcoin News posted on the X platform that Bitcoin Core developer instagibbs stated that he successfully reproduced the reported COLDCARD vulnerability on a newly initialized COLDCARD MK3 device, using only the number of button presses during the setup process, and said, "Sorry, now is the time to panic."He believes the issue affects MK2/MK3 devices but stated that it is currently not possible to confirm whether MK4 has a vulnerability. Developer Antoine Poinsot indicated that the key difference is that MK4 uses a hardware random number generator to provide entropy for the seed and actually uses the microcontroller's true random number generator (TRNG), while MK3 does not. The proof of concept and mnemonic verification are still under review.

According to Jinshi, multiple banks are in talks to provide a $15 billion loan to a data center developer collaborating with Anthropic, with Google providing financial guarantees and chip support.

Ronald Keung, the head of Asian Internet Research at Goldman Sachs, stated that as the global usage of Chinese AI models surges, developers may begin to charge commercial licensing fees to cloud platforms for hosting their open-weight models. Currently, most Chinese models are released under permissive licenses such as the MIT License, allowing any user to use, modify, and host them for free, including for commercial purposes.Keung pointed out that Chinese AI models like Kimi K3 from the Dark Side of the Moon and GLM-5.2 from Zhiyu AI have performance levels that are close to those of leading models in the United States. The adoption rate among small and medium-sized enterprises, both domestically and globally, is very fast, and even large enterprises are beginning to consider using Chinese models. Goldman Sachs believes that model developers can convert the growing use of open-source into actual revenue by requiring third-party service providers to purchase commercial licenses to run model inference on their own infrastructure.

Nine financial institutions and Bitcoin companies announced the joint establishment of the Bitcoin Security Alliance, with founding members including Anchorage Digital, ARK Invest, BlackRock, Block, Blockstream, Coinbase, Fidelity, Galaxy, and Strategy, covering the entire chain of institutions such as custody, trading, infrastructure, payments, and asset management.The alliance commits to providing a total of $15 million in funding over the next three years to support developers and researchers in the field of Bitcoin security, including long-term work to prepare Bitcoin for the future era of quantum computing. Each member independently decides which developers, researchers, or organizations to direct their funding towards. The daily operations of the alliance are coordinated on a voluntary basis by Brink Executive Director Mike Schmidt, with Brink being a nonprofit organization that funds Bitcoin open-source developers.The alliance clearly states that it does not formulate or direct Bitcoin protocols, does not express opinions on specific protocol changes, and does not represent Bitcoin or its developers—Bitcoin development continues to be carried out by a globally decentralized community of contributors. Its positioning is to emulate the model of industry organizations that have long supported open-source software, providing resources and attention to developers without controlling the underlying work.Strategy CEO Phong Le stated, "As long-term holders, ensuring the security of Bitcoin for generations is our greatest incentive"; BlackRock's Global Head of Digital Assets Robert Mitchnick pointed out that the work of Bitcoin core developers is "extremely important," and this commitment will provide "significant additional funding" for Bitcoin's long-term security needs. The alliance will also serve as a reliable source of information for investors, the public, and the media in the field of Bitcoin security, with plans to publish and continuously update materials related to Bitcoin security in the coming months.

According to Bitcoin Magazine, Lightning Labs has released the alpha version of Wavelength, a toolkit that provides self-hosted Bitcoin payment capabilities for developers and AI agents through a simple non-custodial API, without the need to run nodes, manage channels, or obtain liquidity.Wavelength supports on-chain Bitcoin, Lightning Network payments, and settlement layers similar to Ark, with each off-chain payment using standard BOLT 11 invoices, allowing interoperability with existing Lightning Network. AI agents can call the API through the Model Context Protocol (MCP), hold balances, and pay for API calls in the smallest units, among other services. Wavelength is live on Signet and testnet, with mainnet access by invitation only, initially supporting Bitcoin, and stablecoin support planned through Taproot Assets.

Starknet announced the opening of its privacy development stack to developers, launching a privacy SDK and privacy wallet API, allowing applications, wallets, and protocols to integrate private balances, private transfers, and related DeFi interaction features based on STRK20.

According to official news, NEAR Protocol announced the launch of Confidential Intents, opening NEAR's confidential execution infrastructure to all developers. Developers and dApps can provide users with confidential trading features through the NEAR Intents 1 Click Swap API.NEAR stated that Confidential Intents uses encryption rather than proof generation, requiring no client-side proof and not increasing wallet complexity; each user's data is encrypted individually rather than pooled for obfuscation. Integration only requires adding one parameter, with no need for reconstruction. Over $1.5 billion in ZEC has been settled through NEAR Intents, and within weeks of going live on near.com, 42% of transaction volume used the confidential mode, with daily confidential TVL exceeding $30 million.

According to the information, the MiniMax M 3.0 model previously ranked first in the Artificial Analysis open-source model leaderboard.

According to CoinDesk, Bitcoin developers are discussing the removal of the explicit Replace-by-Fee (RBF) signal from the Bitcoin Core wallet. Developer rkrux stated that since full-RBF has become the standard strategy, the BIP 125 RBF signal has become redundant and may leave unnecessary wallet chain fingerprints.Community member Murch noted that stopping the sending of replaceability signals is not simply about removing "fingerprints," as each sender still has to choose a sequence number for each input; currently, about 75% of transactions have used specific sequence numbers, primarily MAX-2. rkrux indicated that the default input sequence number should adopt best practices recognized by a broader wallet community.

According to Rest of World, in order to significantly reduce operating costs, American developers and startups are accelerating the adoption of Chinese AI models such as DeepSeek, Minimax, and Kimi. Due to their high cost-effectiveness in handling common tasks like code writing, the market share of Chinese AI models is rapidly increasing. Data shows that in May, the Token usage share of DeepSeek on the service provider Vercel platform surged from less than 1% to 17%. Additionally, it is reported that Microsoft is also exploring the use of DeepSeek or other open-source models as a low-cost alternative for Copilot.However, despite the popularity of Chinese AI models in the market due to their price advantage, many American companies and developers choose to access these models indirectly through local servers or American cloud service providers, constrained by domestic political scrutiny and data security concerns. This has led to Chinese AI companies facing high usage rates while still struggling to effectively convert traffic into substantial direct revenue and long-term enterprise-level customer trust in the U.S. market.
