A Post-Quantum Path for BIP 324

Bitcoin mailing list post about making BIP 324, the peer to peer encryption BIP for Bitcoin, post quantum secure. https://groups.google.com/g/bitcoindev/c/n_5WuKVYqwI/m/lBooLis3AQAJ

BIP452: P2P UTXO Set Sharing

“PR2137 introduces BIP452, which introduces the possibility to share the UTXO set over the P2P layer. The proposal defines a way to improve the assumeUTXO feature by providing a way for new nodes to receive the UTXO set directly from peers, instead of from external sources.” - bitcoin++ Insider Edition

BIP 450: Formosa—Seed encoding by themed mnemonic stories

Formosa builds upon BIP-0039 by organizing mnemonic words into themed sentences with syntactic roles (e.g., subject, verb, adjective, object, place). Each sentence draws vocabulary from a coherent semantic domain — medieval fantasy, science fiction, nature, finance, or any custom theme — enabling the user to form vivid mental images that reduce memorization effort per bit of entropy. https://github.com/bitcoin/bips/blob/master/bip-0450.mediawiki

BIP 449: OP_TWEAKADD - x-only key tweak addition

This proposal defines a new tapscript opcode, OP_TWEAKADD, that takes an x-only public key and a 32-byte integer t on the stack and pushes the x-only public key corresponding to P + t*G, where P is the lifted point for the input x-coordinate and G is the secp256k1 generator. The operation mirrors the Taproot tweak used by BIP340 signers and enables simple, verifiable key modifications inside script without revealing private keys or relying on hash locks. https://github.com/bitcoin/bips/blob/master/bip-0449.md

Nostr Silent Wallet

Tim Bouma implemented on-chain zaps using silent payments (some related privacy concerns that still apply and some fun technical drama over original on-chain zap PR).

CUBE: Bitcoin smart contracts built on Ark

Cube is a virtual machine designed to enable trusless smart contract execution natively on Bitcoin. Providing a fully trustless execution environment with unilateral exit, Cube ensures users retain complete control over their funds. https://medium.com/cube-bitcoin/introducing-cube-8b3702e470a5

Nimdolf: Non-interactive Mint Delegation on Liveness Failure

This proposal improves liveness guarantees for custodial ecash mints with on-chain reserves. It allows a mint operator to delegate control of mint reserves to third-party mint operators in a non-interactive way. https://gist.github.com/lukechilds/302e7fa04b09d6e4568bdcd64cb43356
