TL;DR: The Community Discussion Around Post-Quantum Transaction Signatures

When NIST finalized ML-DSA as FIPS 204 in August 2024, it gave the cryptography world its first standards-blessed answer to "what replaces ECDSA on the day a Cryptographically Relevant Quantum Computer (CRQC) actually shows up?" Gradually, the conversation has moved from mailing-list theory into working code, with several chains entering the proof-of-concept and performance-benchmarking phase and turning what used to be a thought experiment into a concrete engineering problem. This talk is a TL;DR on where the community discussion around Post-Quantum Transaction Signatures (PQTS) actually stands today. We'll walk through several of the better-known proposals in plain language, looking at how each chain is navigating the trade-offs between signature size, state bloat, verification cost, and migration path. The goal isn't to crown a winner, but to leave you with a clear mental map of the design space and the open questions worth following.
