In this video, I discuss how to sign a Bitcoin message, in order to cryptographically prove that you control a particular Bitcoin address and the Bitcoin associated with it.

For this example, I use a Trezor hardware wallet to sign a message associated with a Bitcoin address that I control, and then I use a different website to verify the signed message.

I also walk through the privacy implications of trusting this external website, which can certainly log my IP address and associate it with that particular Bitcoin address.

If you are not using your own Bitcoin node, then you are using someone else's node whenever you interact with the Bitcoin blockchain.

For reasons of security and privacy, it is always much better to run your own node, in order to eliminate unnecessary layers of trust.
