BTP Litepaper Discussion

Hey y’all. We released the new Litepaper for BTP a few weeks ago (May 2022). This details the decentralized cross-chain transmission protocol that is being developed by the Icon Foundation in collaboration with IconLoop and the Icon Community.

Litepaper means that it is a technical summary. It is focused on communicating the technical protocol designed in support of the BTP product in an academic manner, but it is not intended to be published in an academic journal.


  • On-chain, light client solution
  • Hub model
  • Planned Network Proposal to modify Icon Network to add “BTP blocks”


Please give your feedback! Any key points that you think are interesting, comparisons to existing products, issues that you spot. All of that is more than welcome!
