Hi all,
We have refreshed the proposal for BIP324, a new bitcoin P2P protocol
featuring opportunistic encryption, a mild bandwidth reduction, and the
ability
to negotiate upgrades before exchanging application messages. We'd like
to invite community members to review the BIP[1] and the related Bitcoin
Core
code[2].
The proposal has a rich history[3]. The big changes since the last public
appearance[4] are:
* Elligator-swift encoding for the pubkeys in the ECDH exchange to
obtain a pseudorandom bytestream
* x-only ECDH secret derivation
* Transport versioning that allows for upgradability
* Trafic shapability using decoy packets and a shapable handshake
* Complete rewrite of the BIP text
We look forward to your review and comments.
-Dhruv, Tim and Pieter
