A MORE OPEN INTERNET, A BRIGHTER TOMORROW. INDEX:80 ONLINE
PUBLIC REGISTRY + CARDANO PROOF

REGISTRY/HISTORY

A PUBLIC RECORD OF WHAT INDEX:80 PUBLISHED.

INDEX:80 freezes a copy of its public project registry on a regular schedule. Each snapshot stays available as ordinary JSON, while its SHA-256 fingerprint is published to Cardano so the record can be checked independently.

HOW IT WORKS

THE PUBLISHING PROCESS

Simple by design: one public file, one fingerprint, one manually approved Cardano transaction.

01

LIVE REGISTRY

The current approved INDEX:80 public registry is the source.

02

FREEZE SNAPSHOT

A permanent JSON copy is created for that release.

03

HASH + APPROVE

SHA-256 is calculated and the transaction is approved locally in Lace.

04

CARDANO PROOF

The fingerprint is recorded on Cardano and linked back here.

PLANNED CADENCE: WEEKLYSnapshot preparation can be automated. Cardano signing always requires manual wallet approval.
