Key pillar of blockchain for cybersecurity

Keys pillar of blockchain cybersecurity

Let’s look closer at each of these characteristics:

  • Confidentiality — The blockchain provides extensive capabilities for ensuring a user’s anonymity. User keys are the only link between a user and their data. However, these keys are also easy to anonymize. As a result, while being open and offering rich opportunities for transaction tracking, a blockchain allows users to maintain an unprecedented level of anonymity.
  • Data integrity — Blockchains are designed as ledgers where every block is linked to nearby blocks using cryptographic hash functions. Therefore, once a transaction is recorded on the blockchain, it can’t be altered or deleted. Any changes made to the already recorded data are processed as new transactions.
  • Availability — Having a large number of nodes ensures blockchain resilience even when some nodes are unavailable. And as each node in the network has a copy of the distributed ledger, the correct blockchain remains accessible to other peers even in the case of a compromised node.
