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

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

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).
