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.
