Made Bitcoin 100x harder to crack for a quantum attacker. Stupid simple: force it to solve 100 keys instead of one within 10 min block time.
No fork, no new opcodes, no direct-to-miner relay.

Multisig was designed to distribute trust, we reuse it to multiply the computational work required to forge a Bitcoin spend.
Runs on Bitcoin Core today.

they just evacuated my daughter's school and dozens other schools in all of Rome over a bomb threat
that's a new one

most annoying when your paper last page contains literally ONE line so now I have to go find some sentence to delete cause no way I will have a full extra page in my paper that has ONE line
ugh

Did we push round 39 SHA256 collision attack below 100 bits? Yes we did.
Kudos to @cyberaxe for the method that cut 15 bits at once and @FrostForger for optimisations!

SHA-256 is not broken, but its security margin lost 1 more round this year:
Last week I found a collision attack on reduced 39-round that improves prior art by over 30 bits and the first differential attack on that round better than generic search on @yukonresearch Hashsmash board.

The attack rests on the same method as prior art ePrint 2026/1120 with new insights that first 2 state words could remain free, allowing a critical condition at step 16 rebuilt as a claw-search problem rather than a probabilistic filter. Took days of watching SAT logs, burning cores and arguing with Claude on what's possible to get a result close to generic search.

Since my initial submission, other hashsmash participants sraiw, @cyberaxe, @privacymage, @lamb356_ and @geeknik pushed it down by over 6.5 bits, currently estimated at 118.15 bits. The tree of submissions is hard to follow, so I put the construction, insights and numbers into a blog and am working on detailed technical report.

It's fascinating to see an initial structural observation develop into an improvement in the reduced-round collision frontier within days. AI is now a real aid in cryptanalysis and open collaboration speeds it up.

Saw an exciting and very rare relief today showing a helmeted gladiator combat from 3rd century.
With gladiators being such a part of popular culture, surprisingly few stone carved depictions survive until today. Carving was expensive and rarely done for slaves/worker class, so this person must have been a superstar of his generation!
Found in Diocletian Baths museum in Rome.
