Ethereum Execution Client ethrex Launches Public Testnet for Privacy EIPs

Ethereum execution client ethrex has announced the launch of a public testnet on Glamsterdam to test EIPs tied to the Ethereum privacy roadmap. The testnet supports five EIPs: EIP-8141 (frame transactions), EIP-8250 (key randomness), EIP-8272 (recent root), EIP-7805 (FOCIL), and EIP-8369 (VOPS profile). Each implementation meets the latest specification requirements. The frame transaction implementation aligns with the latest execution spec test release. The testnet is permissionless, allowing anyone to sync, establish peer connections, transact, and fund accounts via a faucet.

a16z Crypto says blockchains need four core capabilities to function as financial infrastructure

a16z Crypto argues that blockchains are moving closer to serving as real financial infrastructure, but raw throughput alone is not enough. In a piece authored by the firm and carried by MarsBit with a Chinese translation by ChainCatcher, the discussion shifts from the old debate over cost and transaction-per-second limits to a broader set of requirements that financial markets impose on any system they rely on. The article identifies four capabilities that matter most: predictable inclusion of transactions, resilient access so participants are not forced through a single gatekeeper, clear and knowable ordering rules, and privacy protections that shield trading intent before execution. It notes that total industry blockchain throughput has risen by more than 100x over the past five years, with some live systems now processing tens of thousands of transactions per second, yet says that speed by itself does not answer whether a trade will be included on time or handled under rules market participants can anticipate. The piece also points to research areas such as strong chain quality, deterministic ordering rules, timelock encryption, and threshold encryption. Its main conclusion is straightforward: if blockchains are to support institutions issuing stablecoins, tokenized assets, and onchain trades, they must meet the operational standards financial markets already expect from core infrastructure.

Trezor says ShipMonk breach exposed about 80,700 customer records, not private keys

Trezor said on Sept. 4 that a data breach tied to logistics partner ShipMonk was much larger than first disclosed, with another 67,000 U.S. customers affected and the total reaching about 80,700 people. The leaked data includes names, email addresses, phone numbers, shipping addresses, and order numbers, while some customers had only partial information exposed. Trezor said its own systems, hardware wallets, private keys, wallet backups, seed backups, and device data were not affected. The distinction matters because the breach did not expose wallet contents, but it did reveal who bought hardware wallets and where they live. That leaves customers open to targeted phishing, extortion, theft, and other real-world threats. Trezor said the newly identified records came from orders placed between November 2019 and August 2021 and should have been deleted. The company said it had repeatedly requested deletion under its contract and data policies and had received written confirmation, but the records remained in ShipMonk’s systems. Trezor is now preparing an anonymous shipping option, including a dedicated checkout flow, locker pickup, neutral packaging, generic sender information, and automatic deletion of shipping identifiers after delivery. The feature is expected in the EU in September 2026 and in the U.S. by year-end, though it will not undo the leak of the roughly 80,000 records already exposed.

Primus Labs and AllScale Partner to Test Private Payroll on BNB Chain

Primus Labs, a zero-knowledge proof computing platform, has partnered with AllScale, a self-custody stablecoin neobank, to test the Private Payroll feature on BNB Chain. The feature uses zero-knowledge proofs to keep salary amounts encrypted while allowing verifiable settlements. Primus stated that the collaboration aims to add confidentiality to existing financial infrastructure, enabling institutions and privacy-conscious individuals to use confidential on-chain financial services without building a separate system.

Google to Mandate Developer Verification for APK Sideloading, Global Rollout by 2027

Google is set to mandate developer identity verification for APK sideloading, starting September 30, 2026 in Brazil, Indonesia, Singapore, and Thailand, with a global rollout by 2027. Critics including Tuta and EFF say the move "Apple-fies" Android, threatening the open sideloading ecosystem that crypto wallets and privacy tools rely on. Google claims sideloaded apps carry over 50 times more malware than Play Store apps, but opponents argue the real motive is control and profit. The policy also introduces limited accounts and advanced flows for users who need to install unverified apps.

a16z Crypto says blockchains need four capabilities to serve as financial infrastructure

a16z Crypto argues that throughput alone will not make blockchains suitable for real financial markets. In a new article, the firm says networks that aim to support onchain trading, stablecoins, and tokenized assets must meet four core requirements: predictable transaction inclusion, resilient market access, clear ordering rules, and privacy before execution. The piece says industry-wide blockchain throughput has increased by more than 100x over the past five years, with some production systems now processing tens of thousands of transactions per second. Even so, financial institutions care about more than speed. They need to know when a transaction will be included, how it will be ranked against other orders, whether access depends on a single operator, and whether sensitive trading intent will be exposed before execution. The article also points to research on “Strong Chain Quality,” a framework intended to reduce dependence on a single queue controlled by one operator, and discusses work on deterministic ordering rules, MEV-related risks, timelock encryption, and threshold encryption. Its central claim is that onchain finance becomes viable only when speed is paired with predictable execution, robust access, unambiguous priority rules, and pre-trade confidentiality.

ECB progress report on digital euro focuses on offline payments, privacy and holding limits

The European Central Bank has released a progress report on the preparation phase of the digital euro, outlining work on three areas at the center of the project: offline functionality, privacy safeguards and holding limits. The report makes clear that the update does not amount to final approval for issuance. Any decision on whether the digital euro is ultimately launched still depends on the European legislative and political process. According to the report, offline payments remain a core design feature because they are intended to preserve cash-like reliability in emergencies, during network outages and in remote areas. Privacy is described as a politically sensitive issue tied to public acceptance, with the ECB trying to strike a balance between anti-money laundering requirements and user privacy. The report also discusses holding caps designed to reduce the risk of large deposit outflows from banks and to protect commercial bank liquidity. The ECB frames the digital euro as central bank money rather than Bitcoin or a decentralized stablecoin, while its ongoing development shows that digital settlement and programmable payments have moved into the policy mainstream.
