Dear Lisk community,

With this email I want to kickstart the discussion and gather your 
feedback regarding the LIP "Introduce robust peer selection and banning 
mechanism". You can find a short summary of the LIP and link to the LIPS 
repository below.


This LIP proposes a new implementation of the P2P layer of Lisk 
introducing a robust peer selection with periodic shuffling and banning 
mechanism. We further suggest to refine the gossip-based flooding 
mechanism for blocks, transactions and signatures in order to improve 
information propagation. Together the proposed changes make the Lisk 
peer-to-peer network ready to scale to a large number of nodes and 
further increase the robustness of the network.
