Permanent On-Chain Data

True Immutability

When you send a message on Obsidian, it becomes part of the blockchain itself. Not stored in a database. Not pinned to IPFS. Not held by a service provider. In the chain.

Your message → Block 12345 → Every node → Forever

What "Permanent" Actually Means

Property	Guarantee
Immutable	Cannot be edited after inclusion
Undeletable	No admin can remove it
Replicated	Copied across all full nodes
Verified	Consensus validates every message
Queryable	Retrievable via standard RPC

How It Works

1. Signed by you — Cryptographic proof of authorship

2. Included in block — Validator commits to message

3. Propagated — All nodes receive the block

4. Finalized — Casper FFG makes it irreversible

5. Stored forever — Part of canonical chain history

Use Cases

• Whistleblowing — Publish evidence that can't be suppressed

• Legal records — Timestamped, immutable documents

• Social permanence — Posts that outlive platforms

• Attestations — Proofs that can't be revoked

Your data. Your signature. Forever.
