Ethereum core developer Sina Mahmoodi announced his departure from the Ethereum Foundation after more than seven years in office. Mahmoodi joined the Ethereum Foundation after graduating from university in 2019 and participated in the development of EthereumJS, eWASM, and the Geth client, with Geth becoming a key infrastructure in the Ethereum ecosystem.He stated that his belief in Ethereum as a decentralized global settlement layer has never changed and that he will take a break before deciding on his next direction.

Cross-border payment company Airwallex co-founder and CEO Jack Zhang stated that stablecoins are becoming an important channel for global capital flow, but sovereign financial systems still determine how to incorporate them, rather than the other way around. As the adoption of stablecoins grows, this trend will intensify. The Central Bank of Brazil has included virtual asset services in its foreign exchange and international capital regulatory framework, Vietnam is working on building a regulated crypto market while banning crypto assets as a means of payment, and the Philippines has indefinitely extended the suspension of virtual asset service provider licenses, all indicating that the adoption of stablecoins will occur within the regulatory frameworks of various countries.He noted that technology is making business more globalized, while financial sovereignty is becoming more localized, and governments will continue to set their own rules for currency, data, identity, and payments. The most enduring stablecoin infrastructure needs to connect sovereign financial systems, provide deep liquidity, and offer reliable conversion between stablecoins and fiat currencies for businesses. Airwallex, with a focus on corporate accounts, has obtained a central bank payment institution license in Brazil and acquired MexPago, the holder of the IFPE license in Mexico, to access the local financial systems of major economies in Latin America. It bets that AI and stablecoins will drive more global business, making regulated local connections more valuable.

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.

According to Finsmes, AI architecture development company Pathway announced the completion of a $30 million seed round financing, with participation from Id4 Ventures, TQ Ventures, Red Bridge Ventures, Kadmos Capital, and WS Investment, an investment institution under Wilson Sonsini. Databricks Chief AI Scientist Jonathan Frankle also joined as an angel investor.Pathway is developing the "Post-Transformer" architecture called BDH (Biologically-inspired Dynamic Hierarchy), aiming to address the limitations of current Transformer models that continuously rely on more data, GPUs, energy, and capital expansion. Unlike traditional large models that require periodic retraining, BDH can continuously learn with less data and achieve ongoing adaptation.It is reported that the company has appointed former Google DeepMind Gemini product head Adam Kurzrok as Chief Product Officer, responsible for the product direction based on the BDH model, including model packaging, evaluation systems, and commercial deployment.

Derek Chiang, founder of ZeroDev and former employee of Offchain, announced his joining of Ethlabs, stating that he will focus on promoting Ethereum technologies such as real-time proofs, light clients, and fast confirmations into practical products and commercial scenarios.He mentioned that the current adoption of many underlying Ethereum technologies is still significantly lagging behind their potential, for example, some cross-chain bridges still rely on multi-signature verification for L1 deposits; he hopes that Ethlabs will become a market force for the implementation of Ethereum technologies, persuading developers to adopt them through technical and product advantages rather than just ideology.

Bankr developer deployer tweeted that the token issuance platform Pools.fun launched by Sushi will release an official protocol token. Among the protocol's total fees, 30% will be used for buybacks and burns, while an airdrop is also planned, and a points system will be established. The trading volume of users and the trading volume generated by deploying tokens on its platform will be taken into account.Currently, fees have started to accumulate and will be used for buybacks once the token is launched. Previously, it was reported that Pools.fun is a joint launch by Bankr and Sushi to compete against the Robinhood chain token issuance platform pools.trade under Uniswap.

Bitcoin News posted on the X platform that Luke Dashjr stated that the developer meeting is "progressing smoothly," and related plans are being advanced, aiming to change Bitcoin's proof-of-work algorithm through a hard fork.The developers are expected to announce the selected hash algorithm tomorrow and enable RTDS starting from the first block. Discussions are also underway regarding block size reduction and replay protection. At the time of this announcement, reports indicated that Dashjr is no longer a licensed user of the BIP content repository. If this proposal is implemented, the change in the proof-of-work algorithm will create an independent blockchain and essentially form a new altcoin, with existing BTC holders receiving tokens on the forked chain.

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.
