Every time I stop and re-start Geth, I wait for it to discover peers. Can I instead export my list of currently connected peers and use them as bootnodes in my next start? I know this list will act as a central peer database but still, more peers should mean more safety, right? I would really appreciate a code snippet for this.

As i know there is not built in option to do so, however you could do it using a script : i am trying here to give you some response elements. the following snippet to output all the connected peers


you need to write a script which read the outputs and use them as bootnodes

  • Great! Thanks. Maybe we need to write (or append) them to a file and read them later to construct the --bootnodes flag. I will try this and share if I succeed. Thanks again for the help!
