OBSIG seals a declaration before the coin exists. Name, ticker, supply, dev buy, what it is for, the declaring wallet and the instant it was signed: hashed once, written to a public record, and readable back as JSON. After the launch a worker re-reads the chain on a schedule and seals each reading with the slot it was taken at. Both halves are published, including when they disagree. OBSIG does not promise a coin will do well. It promises the record cannot be changed.
