Odaily reported that Ethereum co-founder Vitalik Buterin recommended the "The Interfold" project in a post, stating that more people should learn about Interfold. It is a general implementation version of the MACI (Minimal Anti-Collusion Infrastructure) concept he has repeatedly called for over the past decade. Essentially, this project is a privacy protocol optimized for scenarios such as voting and secret auctions, allowing more people to pay attention to and understand this technological advancement.Vitalik also stated that the core mechanisms of Interfold include generating threshold encryption keys, users submitting votes on-chain with ZKP eligibility proofs, performing arbitrary computations within Fully Homomorphic Encryption (FHE) followed by threshold decryption. This enables unconditional voter anonymity, Ethereum-level censorship resistance, and ensures correctness through ZK over FHE, among other strong security guarantees. The main limitation at present is the high cost of complex computations (such as multiplication operations); only additive vote counting is mature. Optimizations based on slashing are being advanced, with a long-term goal of implementing obfuscation techniques to eliminate reliance on M-of-N committees.

Odaily reports that Aztec Labs has announced the acquisition of Obsidion, the development company behind the privacy identity verification tool ZKPassport. The core team of Obsidion will join Aztec Labs to continue advancing the development of ZKPassport and related privacy products.According to the announcement, Obsidion co-founders Michael Elliot and Theo Madzou will join Aztec Labs. The transaction amount and other terms have not been disclosed. Aztec Labs also stated that it will continue to maintain the open-source nature of the ZKPassport protocol and its iOS mobile application, emphasizing its long-term commitment to privacy protection and an open ecosystem.

On-chain sleuth ZachXBT posted on his personal channel that chain tracking analysis shows at least approximately $25 million in presale funds from two investment schemes related to Gurhan Kiziloz show signs of commingling. These funds were transferred to pay for promotions by KOLs and streamers, linked to his online gambling platform. ZachXBT stated that the fundraising materials for the related presale projects, BlockDAG Network and ZKP, did not disclose that the funds would be used to support other businesses. However, on-chain data reveals that after the funds were pooled across multiple addresses, they were transferred via cross-chain bridges to exchanges and then to promotional payment addresses.ZachXBT also named several related addresses, including the Spartans KOL payment address and the BlockDAG / ZKP presale wallets, and advised investors to stay away from the BlockDAG, ZKP, and Spartans projects. Currently, some retail investors are continuously complaining on social media about the use of these funds.

Odaily reports: Binance Wallet has announced the participation threshold for Phase 2 of the zkPass (ZKP) Booster event. Users must have 61 Alpha points to participate, and joining this event will consume 5 points.

According to Arkham data, the zkPass team's multi-sign address (0xEF1) transferred a total of 10,000,000 ZKP to Binance over the past 30 minutes, valued at approximately $796,100.Currently, the circulating supply of ZKP is 268 million, and this distribution accounts for about 3.73% of the total circulating supply. ZKP is currently trading at $0.07964, with a 24-hour decline of 7.35%. Its circulating market cap now stands at $21.37 million.

Odaily News One of the "Big Four" accounting firms, EY, has announced the launch of the EY Blockchain Privacy Sandbox. This is a web-based development environment designed to help businesses and developers experiment with privacy-preserving smart contracts on public chains compatible with the Ethereum Virtual Machine. It is reported that this sandbox environment is based on the open-source technology Starlight, allowing developers to transform standard Solidity smart contracts into applications with privacy-preserving features while retaining the original contract logic. It also provides example projects that can be explored, copied, and modified to accelerate proof-of-concept development.Currently, the EY Blockchain Privacy Sandbox is primarily used for experimentation and validation, supporting enterprises in assessing the feasibility of privacy smart contracts, testing functionalities, and validating application scenarios, completing the verification process before formally integrating Starlight. EY stated that this tool lowers the technical barrier for conducting privacy experiments on public chains by providing an easy-to-use web environment. Starlight, as the underlying ZKP compiler, is already open-source, and developers can integrate privacy features through its GitHub repository. As enterprises' demand for protecting data privacy on public chains increases, attention on zero-knowledge proof technology continues to rise. Related reports indicate that the global ZKP market is expected to reach approximately $7.6 billion by 2033. (PRNewswire)

Odaily News Vitalik posted an article today stating that 2026 is the year to regain computing self-sovereignty, emphasizing that he has begun reducing data leaks to centralized services. Vitalik mentioned that he switched to Fileverse encrypted documents and Signal/Simplex/Session messaging apps (all of which are decentralized open-source applications) last year, and in 2026, he will further transition to OpenStreetMap/Protonmail and decentralized social platforms to protect location and communication privacy.Vitalik also discussed the progress and challenges of locally deployed LLMs, suggesting that combining technologies like ZKP, TEE, and FHE could pave the way for efficient and privacy-preserving computation in the future.
