WebFeb 23, 2024 · Blockchain can be defined as a shared ledger, allowing thousands of connected computers or servers to maintain a single, secured, and immutable ledger. Blockchain can perform user transactions without involving any third-party intermediaries. In order to perform transactions, all one needs is to have a wallet. WebCryptographic techniques are used to ensure secrecy and integrity of data in the presence of an adversary. Based on the security needs and the threats involved, various cryptographic methods such as symmetric key cryptography or public key cryptography can be used during transportation and storage of the data. opticas orsovision ibague
