    Introducing Private Multisig -- a special multisig where no one sees who votes or how votes on proposals. The ballots are encrypted, and the whole voting process is non-interactive. Achieved via ZKP + ECC ElGamal + DKG + HE. Trustless and permissionless. No TEE needed.

    Pumpfun raising $500mil in 12 minutes sets a new bar of idiotism and mental deficiency in crypto. Instead of supporting projects that push the tech frontier by researching the fundamentals of privacy, decentralization, and scalability, we are putting the funds in a shithole of

    Dear @Uniswap, I am writing this letter to you because your dapp is still blocked and can't be used in Ukraine. We had this conversation before and despite my efforts to convince you why it is legal to access the dapp from Kyiv (support ticket 169045), nothing has changed since

    Guys, I think we fucking did it. Today I opened the @Uniswap app and was able to use it from Kyiv without a VPN. It is just amazing what X and public awareness can do. DeFi is for everyone.

    Have you heard of a Cartesian Merkle Tree (CMT)? It's the first Merkle tree with O(log n) complexity that uses just n storage (down from 2n), as all the nodes, not just leaves, store useful information. CMT is deterministic and particularly good for on-chain and ZK applications.

    Introducing ZEX v0.1, a confidential peer-to-peer DEX that requires no protocol-level modifications or co-processors to operate. Privacy assumptions impose very tight constraints, making DeFi use cases almost impossible to implement. Confidential tokens are usually very limited

    I've been building this project for the last 3 years. We now have the biggest collection of on-chain Merkle trees, uint512, Schnorr signatures, various security utils, finance primitives, design patterns, and Bitcoin parsing libs. So close to 250 stars.

    Rarimo and zk-proofs-of-passport is wild magic and I'm proud to be one of the magicians behind the protocol.

    Rarimo - How a Passport Becomes a Digital Identity
    Rarimo turns a physical passport into an anonymous digital identity on the blockchain. The protocol uses Zero-Knowledge proofs to verify that you possess a valid, government-issued passport without...

    My preliminary understanding of the Balancer exploit is the following: The attacker performs a massive "batchSwap", so that tokens are only moved after the entire batch execution, exploiting the calculation of "in" tokens given "out" tokens. During many internal swaps, the swap

    If you understand the math behind the MulDiv library, you are better than 99% of Solidity developers.
