About Stampery

Stampery provides blockchain data certification services. They enable users to certify the existence, integrity, and ownership of data used on the Bitcoin and Ethereum blockchains.

Stampery uses the information transmitted on the bitcoin blockchain to generate dependable proof of existence, proof of integrity, and proof of ownership. Stampery's API lets users prove the existence, ownership and integrity of all their data by inserting unique identifiers for their files and data directly into the blockchains. The timestamps created by Stampery's API can be verified independently by anyone.
