| Bottom line | From its public pages, HCS is the cheapest way here to put hashes on a public ledger at a price you can compute. You build the proof handling yourself, and there is no plan, contract or vendor audit report. | From its public pages, OriginStamp is a long-running anchoring API with two chains, batching and webhooks. The price is an offer, and a few docs pages describe an older anchoring method. | From its public pages, Truestamp has the strongest proof portability here: two chains, self-contained bundles and an open-source offline verifier. Only the free plan can be used today. |
