This post will cover details of the type of cryptography used in Bitcoin and similar Blockchain protocols. Please note that other Blockchains might use alternative cryptographic algorithms. Some Blockchains, for example, use more privacy-preserving cryptography, like for example Zcash (Zero-knowledge proofs), Monero (Ring Signatures). . The dark side of Bitcoin: Misusing cryptography . By For example, someone may put out a contract to kill a significant individual. First, the person willing to carry out the task will have to provide the time and place for the assassination. When the crime is complete, several …

Public key cryptography to the rescue. The genius of public key cryptography is that it utilises two encryption keys. The first key, known as the public key, is used to encrypt information. It can be publicly shared with anyone, for example over the internet. . For Bitcoin Nonce example, proof of work, using hash functions, was considered as a means to combat email spam by forcing email senders to find a hash value for the email (which included a timestamp to prevent pre-computation of useful hashes for later use) that had an arbitrary number of leading zeroes, by hashing the same input with a large
