post-quantum launch attestations

Every launch, sealed.

When a coin launches on QUANT, its launch record is hashed, signed with a one-time hash-based key and chained to the record before it. No elliptic curves: checking it needs SHA-256 only, so it holds up even against quantum computers. Verification runs right here in your browser.

The digest covers the mint, creator wallet, name, ticker, image hash, metadata, website, launch transaction, time and the previous record. Change any of it and the waveform changes completely.

how a launch gets sealed

Hashed. Signed. Chained.

01

Hashed

The full launch record is written as canonical JSON and hashed with SHA-256. That digest is the coin's fingerprint.

digest = SHA-256(record)
02

Signed

A one-time WOTS+ key signs the digest: 67 hash chains, w=16. Each key is a leaf in a Merkle tree, used once and burned.

σ[i] = H^d[i](sk[i]) · climb to root
03

Chained

Every record carries the digest of the one before it. Nothing can be removed or rewritten later without breaking the chain.

record.prev = digest(n − 1)
