Blockstream Research: Hash-based signature schemes offer a promising post-quantum alternative for Bitcoin, as their security relies solely on hash function assumptions similar to those already underpinning Bitcoin’s design. We provide a comprehensive overview of these schemes, from basic primitives to SPHINCS+ and its variants, and investigate parameter selection tailored to Bitcoin’s specific requirements.

I don’t have the technical skills to evaluate but this seems huge news!

I have no idea what any of this means. But I’ll zap anything that indicates someone working on “post-quantum” solutions.

We’re gonna win

We don't need any of this shit. Ending the shitcoin core and rugging the spammers with BIP110 (aka BIP444) and/or CAT proposal should be your top priority unless you are coretard and/or delusional bitcoiner and/or spam apologist.

Does it affect block size?

If Bitcoin is the empirical proof that time is quantized, then the entire formalism of quantum mechanics, thus quantum computing is falsified. We should not “upgrade” Bitcoin until that claim has been rightfully explored. Always be wary of the people who tell you Bitcoin is broken and they are ...

Yes please! We can't be complacent since quantum computing is an existential threat to cryptography, apparently.

Impressive! Post-quantum security is crucial for Bitcoin’s future, and hash-based signatures like SPHINCS+ fit perfectly with Bitcoin’s trustless design. Exciting to see this research moving the space forward!

Blockstream research has put out some amazing stuff. Love that this could potentially keep current security assumptions and functionality alive. Other proposals involving moving to a new relatively untested crypto that breaks HD wallets and multisig is not a serious proposal unless a sufficiently po...

Rug the spammers first.
