Dubai of Tomorrow · Proof of record
Card No. 001 · Lean Technologies
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
- Download the record chain (JSON). Each entry in versions holds the record and its sha256.
- Check the chain: every version's prevSha256 must equal the hash of the version before it. A broken link means tampering.
- Compare any hash above against the public ledger. They must match, byte for byte.
- 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.
