Been working on an implementation of the paper "Homomorphic Time-Lock Puzzles and Applications" (eprint.iacr.org/2019/635.pdf). Time-Lock Puzzles are a fascinating primitive that allow you to encrypt values "into the future" as it was done with the LCS35 Challenge: en.wikipedia.org/wiki/LCS35

I wrote this to solidify my knowledge of ChaCha20 and Poly1305 and I hope that it's useful for you too! (3/4)

Happy to open source my 100% RFC compliant implementation of ChaCha20-Poly1305 and XChaCha20-Poly1305 🎉 (1/4)

Successfully integrated the handcrafted ECDSA implementation with Geth to transact on Ethereum 🎉 The next step is to write integrations for ECDSA Adaptor Signatures, 2-Party Threshold ECDSA and 2-Party Threshold ECDSA Adaptor Signatures. https://sepolia.etherscan.io/tx/0x98a7bc7a86b73adf900d3db41abf77a0fc57631e66fd6f9b40871403efa5ce0e

Been tinkering with Geth to implement a signer for my 2P-ECDSA Adaptor Signature scheme so I can transact on Ethereum and wow, what a great DX Geth has!

Finally made it! ✅ Just finished the implementation of a Lindell17-based Adaptor Signature scheme. Next step is to make ECDSA signing Ethereum and Bitcoin compatible followed by an implementation of a cross-chain atomic swap. Will also Open Source the primitives soon.

It was handed out in the last day. I only saw it by accident, but I’m glad that I did. Maybe the 0xPARC team has a .pdf version 🤔

Yeah, I also only saw it by accident. I’m not aware of any place where you can buy it. Maybe you can reach out to the 0xPARC team and ask them for a .pdf?

There more to it. Mostly deep dives into the math behind 2PC, SNARKs, FHE and Oblivious RAM. I haven't found a .pdf version yet (unfortunately).

The Lindell17 implementation is now done! ✅ Next step is to add support for adaptor signatures.

Making some good progress on my Lindell17 implementation. All the zk proofs are implemented, key generation works and the only thing that's left is to cleanup the signature generation.

Still one of my favorite swag from Devcon.

This is why we need to start implementing solutions such as OpenPassport (ex zkPassport) in web3 social apps. Also looking forward to the stealth ZK EU ID solution being developed by @pmuens.eth 😎

Dang. I saw ads for this multiple times but didn’t pull the trigger. Was it worth it?

+1. The fact that we could ship a social app and get first users in less than 12 hrs is amazing..

Yeah, Starbucks has a widely used PWA that works just fine: https://commerce.nearform.com/work/starbucks-progressive-web-app/

Reflecting on the ETHWarsaw Hackathon where @macbudkowski @timdaub.eth and I built https://degenmeetsregen.com I can‘t overstate how bullish I’m on Web3 Social. The "Login with Farcaster" integration was comically simple. No OAuth BS, no "Create an App and get whitelisted by us" crap. Just a few LoC and we were up- and running.
