The core features of blockchain technology are:

Decentralization: Blockchain operates on a network of nodes, with no central authority or intermediary controlling the system. All participants have access to the same information, and any changes to the blockchain require consensus among the network.

Security: Transactions recorded on the blockchain are secured using cryptographic techniques. Each block contains a unique hash that links it to the previous block, creating a chain of blocks. This structure makes it difficult for malicious actors to alter past transactions without detection.

The process of detecting, evaluating, and prioritising risks in order to lessen or reduce their impact on a company or an individual is known as risk management. It entails identifying potential risks or uncertainties that could affect goals and then taking the necessary steps to manage or react to them.
