I find it hard to believe that something like this is not possible, as the use of public/private keys is a major bonus of digital identities.
I need to write a Javascript function to take in an ethereum address and return its public key. I know how to get the public key from a signature, but it is harder than I thought to get a transaction signature, web3 cannot return one I believe.
Can I use something in ParityJS to grab a transaction hash from input address account, and get the signature from it?
Someone please tell me this is possible, I am losing hope...
