Ethereum developers are advancing a zero-knowledge protocol aimed at enhancing the privacy of on-chain interactions. The first application of this protocol is a “Secret Santa” matching system, allowing participants to randomly exchange gifts anonymously, laying the groundwork for broader future private coordination tools.
Solidity engineer Artem Chystiakov shared relevant research on the Ethereum community forum, where he first published his findings on arXiv in January this year. The solution allows participants to register Ethereum addresses and verify the relationship between the sender and receiver through zero-knowledge proofs without revealing their identities. At the same time, transaction relayers are used to submit transactions, avoiding the association of personal wallets with operations, ensuring anonymity.
In the proof of concept, each participant submits a unique digital signature and a random number, broadcasting the transaction through a relay to ensure that no one can trace the submitter. The receiver uses these random numbers to encrypt the delivery details, which can only be decrypted by their designated “Santa Claus”. After the match is completed, the protocol only discloses the identity of the receiver to the designated sender, keeping complete anonymity for other participants.
The system addresses long-standing issues of randomness, privacy, and resistance to Sybil attacks on the blockchain, while providing a reference for the construction of Ethereum's privacy framework. The zero-knowledge layer can be applied in the future to anonymous voting, DAO governance, reporting channels, or private airdrops and token distributions, facilitating the secure coexistence of encryption systems in privacy and regulated financial scenarios.
This innovation demonstrates the potential of zero-knowledge technology in protecting on-chain identities and transaction privacy, bringing more practical privacy tools to the crypto ecosystem. (CoinDesk)

Robert Kiyosaki warns of a “fake coin” crash, insisting Bitcoin is the safest asset for 2026
Robert Kiyosaki, in a recent post, said that Bitcoin and Ethereum could become the safest investments of 2026, because the United States continues to print money, debt is rising, and inflation is worsening. He criticized the safety of U.S. Treasuries as “the biggest lie,” and noted that real assets and cryptocurrencies can preserve wealth during inflation. His investment recommendations include holding Bitcoin, gold, silver, and commodities. Although some of his predictions weren’t accurate, some of his long-term predictions have come true.
