Bitcoin PQC outputs and Ethereum PQ signatures plus ERC-8415

Post-quantum cryptography proposals led activity on Bitcoin and Ethereum forums. Separate threads examined ERC-8415 mechanisms for registry latency in real-world asset and NFT settings.

Bitcoin PQC output types and CISA bundling

Sipa initiated a Delving Bitcoin thread that centralizes discussion of PQC output types including P2MR and P2TRv2 together with CISA bundling for quantum resistance. Eight participants exchanged 27 messages on the constructions. The exchange matters for developers tracking how Bitcoin may harden transaction outputs against quantum threats.

ML-DSA verification precompiles

A small Ethereum Magicians thread proposed ML-DSA verification precompiles in a draft EIP and debated tradeoffs versus EIP-8288 STARK aggregation for post-quantum signatures. Three participants contributed nine messages on efficiency and security options. The comparison is useful for Ethereum developers preparing on-chain signature verification for a post-quantum setting.

ERC-8415 load leveling for RWA registries

Two participants discussed how ERC-8415 uses asynchronous buffering to decouple settlement speed from off-chain registry throughput for real-world asset latency. They clarified that downstream rollback remains an application-level concern. The approach addresses practical performance limits in tokenized asset systems.

Asynchronous NFT register projection draft

An author posted an early working draft of ERC-8415 covering time-indexed NFT holder projections and received limited UX-focused replies. Two participants took part across eight messages. The draft extends registry projection ideas relevant to NFT application builders.
