<p>The implementation relies on BitcoinJ's NioClient attempting a handshake, but if that fails (for example when there isn't a locally running Bitcoin node), NioClient logs errors and exception to console, which is a bit annoying since we're already properly handling each case. Here's a screenshot:</p>

<p>We could get the relevant BitcoinJ's logger and suppress it while we're doing these checks, but that feels a bit hacky (or does it?). Tell me how you feel about that.</p>
