Title: Do I need to sync with the network to sign a message ?
Post by: OmegaStarScream on February 04, 2016, 08:30:13 AM
I'm wondering if I need to download the whole blockchain to be able to sign a message ? I'm using Bitcoin Core btw .

nope. just tried it and it works fine. heck I didn't even connect to the internet. so I'm sure all you need is the private key.

I see , thanks then and I assume that It should be the same for verifying since you don't even need a private key for verifying signed message unlike signing them.

Correct, signing and verification happen locally and no blockchain data is needed.
