Blind trust is a term commonly used to describe a situation where a person trusts another implicitly, without any evidence or rational basis for doing so. However, there are many other synonyms that can be used to describe this type of trust. Faith, confidence, reliance, conviction, and certainty are all words that can be used to convey the idea that someone is placing their trust in another person or institution without any visible proof. Some other synonyms that could be used include unquestioning trust, total trust, unquestionable faith, and unhesitating belief. Ultimately, blind trust is about putting your faith and trust in someone else, even when you don't have any rational reason to do so.
