Syncing a Bitcoin Node: Tips and Tricks

Does syncing a node take longer over time? Seems like it would, right?

Actually, it’s getting quicker. The blockchain hasn’t ballooned much since 2014, barely hitting 600GB. And our internet speeds? Way faster now! Used to be 2-5 mbps, now we're talking 500-1000 mbps.

But the blockchain grows daily, so syncing a 200MB node vs a 900MB one... definitely different stories. Still, the recent updates made the sync process more efficient. Try syncing with an old version, you'd be waiting forever.

When was the last time you synced a full node? IBD requires more resources now. With the UTXO set around 12GB, you really need extra RAM. A big dbcache helps too, otherwise, you’re bottlenecked.

Good point, but remember, everything’s gotta be processed. So your CPU is key too. If it’s slow, that might hold you back.

Download speeds aren't the focus with IBD anymore. It’s about I/O, CPU, and RAM. Ideally, keep chainstate in RAM during IBD to speed things up.

Can I run a full node on a local server and connect my wallet on a different PC? How would I set that up?

Absolutely, you can do that. You’ll need rpcbind and rpcallowip in your bitcoin.conf to allow connections.

Just make sure you do this locally. Connecting publicly could expose you to risks. Who knows who’s tracking that data?

FYI, RPC isn’t encrypted. SSL support got dropped ages ago. It’s safer to have a secure direct tunnel to your computer instead of using unencrypted RPC.

Yeah, I should’ve said unencrypted. And there’s a way to set up a TLS tunnel to a bitcoin node using stunnel. I can dig it up for you if you want, just need to find it on my server.
