If you have 8 connections, then it means you are only doing outbound connections which might be the case if you just want to use your client to execute your own personal transactions, not verify everyone else's. If you have more than 8 connections, then it means you are accepting inbound connections and are acting as a full node good for you.

Two additional ways to get information about your node is to use GetNetTotals which returns information about network traffic, including bytes in, bytes out, and the current time, and GetNetworkInfo which provides information about your connections to other nodes. You can also just tail the debug. It shows current block height i. If your block count matches the block height from those sites, your block chain is in sync.

If it does not match the difference in block height is how far you are behind approximately 10 minutes per block.

In other words, how can I detect whether blocks lower down in the array need to be replaced? How frequently does this happen?

Active Oldest Votes. There are also two forks: One branching off at height and extending to height It has status "valid-headers", which means we heard about the headers for this block, but by the time they were verified, we already had an equivalent or better block available, so we did not attempt to download the forked block at height One branching off at height and extending to height It has status "valid-fork", which means we actually heard about this block at a time when it was the best block, and proceeded to download and validate it, which was succesful.

Later the branch was overtaken by the branch that is leading up to our current tip. Pieter Wuille Pieter Wuille Do you also know what headers-only means? Why would a node receive a block header headers-only but not download the rest of the block?

Or to put it another way, why would a node download a full block valid-headers if the node knows that we already have a valid block at the same height? In that case we don't bother downloading the rest of the block data. Question 1 The chain with the most work needs to be the tip.

I'm assuming you are working through bitcoind: So I would simply go through the a list of all blocks received ever A-E and X-Z in my array and find the block with the most total work.

Question 2 You can then count forks that your node has seen in a couple of ways: checking any blocks that are referenced by as the previousblockhash by multiple blocks. Louis Louis 6 6 bronze badges.
