Ensuring transparency means keeping data safe The very nature of the blockchain as a decentralised system is said to be the reason for its immense security and credibility . Matching current transactions with previous data , not only does the blockchain store information , but it leads you to its origins .
“ When a new transaction is made , it is matched with the endpoint of the previous transaction , creating a string of events with each one validated through consensus ,” says Aldegren . “ This continuous chain is why a blockchain is often considered to be highly secure from the risk of tampering . This argument is only valid in the context of a public blockchain .”
