Vitalik: The Diamond iO exploration program "stealth" new paradigm may drive privacy computing into a new stage

Ethereum co-founder Vitalik Buterin published a new article introducing a novel cryptographic obfuscation technology called Diamond iO. This technology aims to address the extremely low efficiency of traditional indistinguishable obfuscation schemes, allowing programs to run while hiding internal logic and critical data. Although traditional iO technology possesses strong privacy protection capabilities, its operational costs are prohibitively high, making it nearly impractical. Diamond iO, by adopting more aggressive new cryptographic assumptions, enhances computational efficiency from "universe-level time consumption" to "planet-level time consumption," bringing it closer to practical application.Diamond iO is built on technologies such as Attribute-Based Encryption (ABE) and Fully Homomorphic Encryption (FHE). By encrypting programs, it allows users to execute the encrypted programs and obtain correct outputs without being able to view the internal code or hidden keys. This solution introduces a new input encoding mechanism and conditional decryption method, reducing computational complexity while ensuring the program logic remains hidden. Its core application scenarios include protecting programs that contain private keys, enabling secure software licensing, constructing trustless cryptographic services, and supporting blockchain and artificial intelligence systems with stronger privacy protection.However, Diamond iO is still in the early research stage, and its security relies on new cryptographic assumptions, including All-Product LWE and Evasive LWE, which require further research validation. At the same time, the technology still faces efficiency challenges such as high computational overhead and circuit depth limitations. Researchers believe that by optimizing underlying hash functions, improving homomorphic encryption schemes, and reducing security parameter requirements, Diamond iO is expected to become an important direction for advancing practical program obfuscation technology in the future.

Base Build launches Verify Onchain, using on-chain identity verification to solve the airdrop witch attack problem

According to official news, Base Build announced the launch of Base Verify Onchain to address the issue of witch attacks in the blockchain ecosystem. This feature has been launched on the Base Sepolia test network, allowing developers to implement the "one real user, one claim" rule in smart contracts. Base Build stated that traditional airdrop mechanisms are easily manipulated by bulk wallets, and a large number of rewards are often obtained by professional airdrop farmers, while users who genuinely participate in product development can only receive limited benefits.Base Verify Onchain helps project teams identify multiple wallets controlled by the same user by generating a stable identity hash for each real user, without needing to obtain users' names, account information, or other private data. Users can complete verification through existing accounts such as Coinbase, Instagram, X, and TikTok. The system then returns a verified identity credential to the smart contract, which automatically enforces rules such as claim limits, voting restrictions, or quota controls. Currently, Base Verify has been used over 300,000 times and serves collaborative projects such as Base App, Cody, Scratch, and Bracket. Base Build stated that Verify Onchain will provide fairer airdrops, token distributions, governance voting, and user incentive mechanisms for decentralized applications. Developers can use this technology to limit the number of claims per real user, allocate rewards based on real identities, or convert real-world signals into on-chain credibility, thereby reducing the impact of bots and multi-wallet manipulation on the fairness of Web3 applications.
