Blockchains are secured through a variety of mechanisms that include: - Advanced cryptographic techniques - Mathematical models of behavior - Decision-making.
Consensus refers to the ability of the nodes within a distributed blockchain network. Typically, the process of achieving consensus is dependent on the so-called consensus algorithms. Immutability, refers to the ability of blockchains to prevent alteration of transactions that have already been confirmed.
Blockchains rely heavily on cryptography to achieve their data security. The so-called cryptographic hashing functions are of fundamental importance.
