See #1345, <https://github.com/paritytech/substrate/pull/14207>. This adds all the necessary mixnet components, and puts them together in the "kitchen-sink" node/runtime. The components added are: - A pallet (`frame/mixnet`). This is responsible for determining the current mixnet session and phase, and the mixnodes to use in each session. It provides a function that validators can call to register a mixnode for the next session. The logic of this pallet is very similar to that of the `im-online` pallet. - A service (`client/mixnet`). This implements the core mixnet logic, building on the `mixnet` crate. The service communicates with other nodes using notifications sent over the "mixnet" protocol. - An RPC interface. This currently only supports sending transactions over the mixnet. --------- Co-authored-by: David Emett <dave@sp4m.net> Co-authored-by: Javier Viola <javier@parity.io>
