Trusted timestamping

A timestamp is a proof of existence of a document at a certain time relying on the security of the blockchain and the cryptographic hash function. Applications may involve a digital signature verification, a defensive publication. Blockchain is an immutable transaction log of a distributed ledger database. After finalization a timestamp cannot be changed. Blacknet is a decentralized network that maintains a public blockchain. Trusted timestamping will be implemented in version 0.3 on the proof of stake blockchain.
