Node software whitelisting #20

Open SurfingNerd opened 3 years ago

SurfingNerd commented 3 years ago

One of the problems we have encountered was due the fact that the P2P communication picks up all kind of node software and all kind of (Ethereum like ?!) networks. Since DMD is it's own ecosystem, it is not required to talk to ethereum, rinkeby, xDai, and so on. Therefore, we can just whitelist our software version and stop communication with other nodes. That would especially a big leap for the #15

Disabling peers Nodesoftware whitelisting does not block peers for the future. example filtered grep output. The same Peers get disabled over and over again.

Thesis: It is just the besu client software that keeps to be tenacious to try to reconnect, if there was a communication in the past.
