The SAP solution architect explained that the blockchain registry was originally designed to check the validity of records across the entire database chain every few minutes, so any changes to it are immediately recorded. Why does this happen? The fact is that the blockchain is formed as a continuously growing chain of blocks with records of all transactions, and the information in the blocks is not encrypted and is available in open form in a single database. “The cluster of blocks is called a hash, and if changes are noted in any of the blocks, then the chain of transactions changes,” the expert says.

important feature of blockchain: it eliminates the need for information intermediaries: “When using financial services, you usually rely on intermediaries whose only function is to verify the malta mobile database being transferred (for example, when making payment transactions, the bank checks the availability of funds in the client’s account).” Ed Moyle, research director at the information security association ISACA, said that unlike the traditional accounting system, which is built with government security standards in mind, blockchain relies on self-defense.

Cisco senior blockchain project manager Enup Nanra says blockchain security is not so much about advanced cryptography as it is about its openness: “Transactions are posted publicly on the network, then hashed, frozen, and verified. The transactions are then linked into consecutive blocks, and so on in a circle. The security guarantee of the technology is that to crack any block of interest to a hacker, they would have to crack the cryptographic block, and even after cracking it, this operation would have to be repeated for every node in the network, which is a virtually impossible task.”
