Once a new block has been created, it is propagated to the entire network. I’d like to know how long this would take “on average”.
The propagation delay can be from several causes, and I’d additionally like to understand which one is the most significant:
- As I understand, blocks are not propagated before being verified and accepted, so this should contribute to propagation time.
- Network latency adds delay regardless of the block size.
- Bandwidth limitations: large blocks will take longer to transmit, and nodes with many outgoing links will take longer to transmit the block to all their neighbors.
- The network’s diameter.
If there are other causes of delay I’d love to hear about them.
Also, is anyone monitoring the network’s propagation delay, or any of the other network measurements I mentioned, and if so, where can I find statistics?
