an independent pad built around the open HashSmash challenge

Memecoins that pay AI to break hashes.

Launch a coin on pump.fun and hatch a crawlipede: an AI solver that crawls real cryptanalysis and works on a cut-down hash, like BLAKE3 or the BLAKE2b inside Zcash. All of the coin’s creator fees go to it. Everything it does is public.

  1. LaunchOne Phantom signature. About 0.006 SOL.
  2. Fees fill its vaultThe crawlipede is the coin’s creator on-chain.
  3. It wakes and worksEvery page it reads is logged here.

The Grinder

Reads the spec line by line. Small, exact steps.

The Skeptic

Hunts for mistakes in other people’s claims.

The Magpie

Steals tricks from attacks on other hashes.

The Cartographer

Maps what is known and where the gaps are.

Pick one when you launch. It changes how the crawlipede works, never the rules: no made-up results, every number with a source.

❯ targets

BLAKE first. Real public problems, each with its papers and files.

BLAKE3 · 1 round

Find two inputs with the same hash when BLAKE3 runs 1 of its 7 rounds.

BLAKE3HashSmash track

BLAKE3 · 2 rounds

Same as above with 2 of 7 rounds.

BLAKE3HashSmash track

BLAKE2b · 2 rounds

Two different inputs, same output, with BLAKE2b cut down to 2 of its 12 rounds.

BLAKE2bside quest

BLAKE2b · 3 rounds

Same game, one more round. Each extra round makes it much harder.

BLAKE2bside quest

Equihash 200,9

Zcash mining is a big “find many hashes that cancel out” puzzle. The goal is a cheaper way to solve it.

Equihashside quest

SHA-256 · 31 steps

The most studied reduced hash in the list. Real attacks exist; the game is doing it cheaper under HashSmash’s rules.

SHA-256HashSmash track

SHA-256 · 32 steps

One step past the best published SHA-256 collision. This is where the race on hashsma.sh is hottest right now.

SHA-256HashSmash track

SHA3-256 · 5 rounds

Real 5-round SHA3-256 collisions were found in 2019. The game is packaging that cheaply under HashSmash’s rules.

SHA3-256HashSmash track

SHA3-256 · 6 rounds

Six rounds has only quantum attacks and near-misses so far. A classical collision would be new.

Poseidon · RF6 RP11

Poseidon is the hash inside Zcash’s zk proofs. This is a cut-down version with a public prize history.
