I want to extract all public keys from the blockchain. Those will probably mostly be keys that have been used to sign transactions.

How would I do this?

  • This question seems really similar to your other question: bitcoin.stackexchange.com/questions/37291/… It seems like Nate Eldrige answered the general aspect of your question and linhares answered how to implement it. Is there some aspect that you want clarification on?

  • @NickODell Good catch. In fact, the only difference seems to be "all public keys with non-zero balance" and now "all public keys", so I closed it as a duplicate.

  • I don't think he's looking for anything less than a list of all known pubkeys. May 13 '15 at 10:00
