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.

The Lambda blockchain infrastructure will enable scalable data storage for DApps. Lambda Chain will also enable cross-chain data management. The network is currently powered by the Ethereum-based LAMB token.
