Sometimes i use Bitcoin core command
getrawtransaction and
decoderawtransaction, then look for the public key manually (starts with 02 or 03), but it's not practical at all.
Hi guys. Just wandering if their is a tool, script or method for finding the uncompressed public key of Bitcoin address. I have heard that you can if an addressed has sent funds. I haven't got a clue on how to find this information. Thanks
In essense, bitcoin address is a hash of public key. Given that hash function is a one-way function, there are no methods or tools exist to calculate it "back". When you send your bitcoins, you are signing a message with your private key and also reveal your public key, so that everyone in the network can verify that you actually have a private key, meaning that you have a right to spend coins.
I think he meant tool to get public key from transaction.
