This way, if it needs a lot of blocks, it will only request new ones as previous requests are fulfilled, allowing the peers to control the pace of updates and not overwhelming the network. On a node running the Bitcoin Core client, you can list the peer connections with the command getpeerinfo:. Almost all full nodes also help the network by accepting transactions and blocks from other full nodes, validating those transactions and blocks, and then relaying them to further full nodes. This operation differs by operating system: Keep in mind that new nodes require other nodes that are willing to serve historic blocks. Full blockchain nodes maintain a complete and up-to-date copy of the bitcoin blockchain with all the transactions, which they independently build and verify, starting with the very first block genesis block and building up to the latest known block in the network. Fewer nodes will result in less traffic usage as you are relaying blocks and transactions to fewer nodes. If valid, they are removed from the orphan pool and added to the transaction pool, completing the chain that started with the parent transaction. It will then receive an inv message from its peers containing the hashes of the next blocks in the chain.
