Without account passwords or manual review, how does the blockchain know that a transfer was sent by you?
Signatures are secure because of the elliptic curve discrete logarithm problem: calculating a public key from a private key is fast, but deriving the private key from the public key is practically impossible.
A signature is bound to the specific content it signs. Change even a single byte, and the original signature will no longer verify.
Learning this won't make me money right away, but it can help me avoid a few basic mistakes.
Don't put all your savings into a single project.
