What is email confirmation for?
PICTURE THIS: A SENTENCE BECOMES TOKENS
The model does not read letters like humans. It reads these pieces, then predicts the next one.
Simple meaning
It proves the user owns the address before trusted actions.
WHY — Identity instead of guessing?
Why interviewers care about Identity:
who only read docs from people who shipped.
and tied to .NET MVC work.
Name the idea, why it exists, then one short example.
End with when you use it and one common pitfall.
STEPS — What happens with tokens?
Before the model can read a sentence, it goes through these steps:
- 1It proves the user
owns the address before trusted actions.
- 2Token IDs
Tokens expire.
- 3I block sensitive features
until confirmed when risk is high.
- 4Context mix
Attention looks at nearby tokens together.
- 5Next token
The model scores what should come next.
- 6Decode
IDs turn back into readable text.
EXAMPLE — See it in action
Let's see how a real sentence is tokenized (tokens may vary by model):
Note: Actual tokens and IDs depend on the tokenizer (e.g., GPT, Llama, etc.).
Key takeaway
It proves the user owns the address before trusted actions. Tokens expire.
