The same qualities that make blockchain valuable for regulatory compliance and accountability make it a worthwhile tool in protecting data integrity. "Blockchain is a decentralized, tamper-proof mechanism. It holds all the information the systems need to operate, from passwords to policies," says Greatwood. "No one node has all the information required to make any change."
Other vendors use blockchain qualities like the linked timestamping that is a critical part of Bitcoin to verify the integrity of data within the blockchain. Guardtime, which had the initial business responsibility for creating a formally verifiable security system for the Estonian government, has expanded its offerings to include integrity verification for both commercial and government customers.
Because a blockchain will record and verify any change to the data, it is an inherently suitable tool for protecting (and verifying) the integrity of a data set.
