According to Mars Finance, as reported by CoinDesk, Ethereum developers are refining a zero-knowledge protocol aimed at providing stronger privacy protections for on-chain interactions, starting with a matching system similar to a “Secret Santa” that is expected to evolve into a broader set of private collaboration tools. Solidity engineer Artem Chystiakov mentioned this research again in a post on the Ethereum community forum on Monday, referring to his related work first published on arXiv in January this year. The idea aims to recreate an anonymous gift exchange game on Ethereum, where participants are paired randomly, and no one knows who is giving gifts to whom. However, achieving this on a transparent blockchain requires solving several long-standing issues surrounding randomness, privacy, and resistance to Sybil attacks. Chystiakov stated that the core problem is simple: “Everything on Ethereum is visible to everyone,” the blockchain cannot provide true randomness, and the system must prevent users from signing up multiple times or assigning gifts to themselves. The proposed protocol uses zero-knowledge proofs to verify the relationship between the sender and the receiver without disclosing identity information, and it also employs transaction relays to submit operations, so that a single wallet cannot be linked to specific actions. This type of zero-knowledge layer could be applied to anonymous voting, DAO governance, reporting channels, and private airdrops or token distributions that avoid disclosing recipient information.

ETH drops 0.85% in 15 minutes: ETF inflows weaken and large holders cut positions, triggering spot selling pressure
2026-04-08 14:30 to 14:45 (UTC), the ETH spot market saw a rapid pullback, with the return rate recording -0.85%. The candlestick price range fluctuated between 2202.51 and 2227.59 USDT, with a swing amplitude of 1.13%. During this period, trading volume rose by about 10% versus the previous hour on a quarter-hour basis, short-term market volatility intensified, and mainstream investor attention noticeably increased.
The main driving force behind this unusual move is that the ETF capital inflow momentum, which was strong on April 6, significantly weakened on April 8; institutions and some of the capital that had flowed in earlier chose to realize profits in the spot market, bringing concentrated selling.
