In episode 15, Bill architected a solution to ensure all the users on his blockchain were given a unique identifier. His approach consisted of essentially leveraging the randomness of a user’s private key to ensure each identifier is unique. A disadvantage Bill pointed out with this is that a user may forget their private key and ultimately lose access to their account. To circumvent this issue, Bill proposed the usage of a mnemonic, that is composed of 12 to 24 words, to act as the private key since it’s simpler to keep track of and hard to guess.
In this video, Bill will add additional validation mechanisms to his blockchain nodes. Bill will do this to verify the authenticity and destination of a transaction. Bill will read the first byte of the signature to determine if a transaction is destined for his nodes. Next, He’ll check if the signature is following the rules defined in his protocol. Watch and learn how to implement additional security on your blockchain and calculate a user’s address from a transaction’s signature.
