So, these are keys that are used within digital signature schemes, and so we can assume that Alice has generated this key at some point, and that she made it public, and that Bob did the same thing, and so now they both have identities within the system, and these identities are just sequences of numbers that correspond to public keys for verification in the context of a cryptographic digital signature. This meant that their transaction data was the same, and so the TXIDs were the same also. Typically, a transaction's status can be determined by the number of confirmations it has received on the blockchain. The signature also prevents the transaction from being altered by anybody once it has been issued. Bitcoin wallets keep a secret piece of data called a private key or seed, which is used to sign transactions, providing a mathematical proof that they have come from the owner of the wallet.
