![]() ![]() The Notary service then calculates a single hash by using the received file hashes, and then sends the new hash to the Etherium (Blockchain-based distributed computing platform). ![]() It is impractical to store big chunks of data in a blockchain, which is why Acronis products will only send file/backup hashes to the Notary service. To summarize, a blockchain is an append-only database with transaction order and the following data protection properties:Īcronis Notary service: How does it work?Īcronis Notary is the universal solution for timestamping and fingerprinting any data objects and streams. If someone attempts to cheat the system, they can be easily identified. The blockchain creates trust because a complete copy of the chain, which shows every transaction, is held by the entire network. So, the consensus of nodes is required to add the block into the blockchain. Whenever new transactions occur, the blockchain is authenticated across this distributed network, before the transaction can be included as the next block on the chain. The blockchain resides across a network of computers (nodes). ![]() No centralized "official" copy exists and no user is "trusted" more than any other. Every node in a decentralized system has a copy of the blockchain. It consists of data-structure blocks that may contain data or programs, with each block holding batches of individual transactions, and the results of any blockchain executables. A blockchain is a distributed database that maintains a continuously growing list of records that are secured from tampering and revision. ![]()
