Dubai of Tomorrow · Proof of record

Card No. 028 · Keyper

Founder profiles are living documents. When the story evolves, a new version of this record is created and anchored. Nothing is rewritten silently: every version below is hashed, linked to the one before it, and timestamped on Bitcoin via OpenTimestamps. This is the Anchored Record Protocol, applied to one card.

Verify this yourself
  1. Download the record chain (JSON). Each entry in versions holds the record and its sha256.
  2. Check the chain: every version's prevSha256 must equal the hash of the version before it. A broken link means tampering.
  3. Compare any hash above against the public ledger. They must match, byte for byte.
  4. Drop a version's .ots file and its hash into opentimestamps.org. Bitcoin tells the truth about when that hash existed. No trust in Dubai of Tomorrow required.

What the statuses mean: Bitcoin attested · the timestamp is confirmed in a Bitcoin block. Attestation pending · the hash is anchored with OpenTimestamps and awaiting Bitcoin confirmation, usually within hours; until then, git history is the backstop.
