in the ecosystem of a single blockchain, they are the single source of truth that is an open api-like thing that no company can control
therefore it’s safer to build then on twitter, facebook, apple, etc.
the entire ecosystem may be a fraud, but if it is not then it’s incredibly enduring. i have more faith that i can get what the balance of an account is in 10 years from ethereum than i do from my banks api staying stable or open.
