#signdigitalsovereigninfra $SIGN @SignOfficial Tokenization is a fundamental concept in modern computing and artificial intelligence. A token represents a unit of data, such as a word, character, or symbol, that algorithms can process efficiently. In natural language processing, text is broken into tokens so models can analyze meaning, patterns, and context. Tokens also play a crucial role in security systems, where they act as digital keys to verify identity and grant access. From blockchain to APIs, tokens enable communication, authentication, and value exchange. Understanding tokens helps developers design smarter systems, improve performance, and build more secure and scalable digital solutions across many modern industries
