Cryptography is the process of converting ordinary text into unintelligible text and vice-versa. It is used to store and transmit data so that only those intended can read and process it. Cryptography protects data from theft or alteration and authenticates users.^[1]

Trust

An entity trusts another entity when the first one makes the assumption that the second one will behave exactly as the first entity expects.^[2] Trust is predictability. Identification, authentication, accountability, authorization, and availability support confidence in predictability. Trust is a set of binary relationships based on individual identity or unique characteristic validation.^[3]

In computer science, trust refers to the generation of authorities or user access/privileges through cryptography.
Zero Trust (ZT) is a cybersecurity paradigm concerned with moving defenses from static, network-based perimeters to a focus on users, assets, and resources.^[4]
Cryptocurrencies use proof of work (PoW) to achieve trust.
Trusted certificates create secure connections to a server via the Internet.
Trusted Notifiers
