What gets published?
01Your content stays local
The browser computes SHA-256 from the exact bytes.
02Your wallet signs a memo
One memo instruction. No transfer, token approval or server-held private key.
03The ledger is the receipt
Verification requires successful execution and finalized commitment.
A digest is evidence of publication, not evidence that the original content is true. This workflow does not attest to physical radio transmission or BLS consensus.
