I am syncing the blockchain with geth and I type "eth.syncing" to check the progress. I notice that "highestBlock" does not change. It's the same as it was when I started syncing a few days ago.
I assume it refers to the highest block at the time I started. So my question is what significance that has. Will the RPC start to work when I catch up to "highestBlock" or only when I catch up to the actual, current highest block?
