Continuing the discussion from Blockchain Security:
Blockchains are secured through a variety of mechanisms that include advanced cryptographic techniques and mathematical [models of behavior and decision-making]. Blockchain technology is the underlying structure of most cryptocurrency systems and is what prevents this kind of digital money from being duplicated or destroyed.
The use of blockchain technology is also being explored in other contexts where data immutability and security are highly valuable. A few examples include the act of recording and tracking charity donations, medical databases, and supply chain management.
However, blockchain security is far from being a simple subject. Therefore, it is important to understand the basic concepts and mechanisms that grant robust protection to these innovative systems.
