Design Update: Split DKG and Handoff Operations #66

Open EmbeddedAndroid opened 1 year ago

EmbeddedAndroid commented 1 year ago

We need to update the design based on the discussion at the Signer hackathon. In the current design, the PoX prepare phase is distinct from the Handoff phase which contains both DKG and Signing. One problem with this, is that we need to separate DKG and signing to distinct phases. In addition to this, the new Nakamoto consensus rules allows us to run the consensus prepare phase in parallel with these phases, and run DKG immediately since the set of Stackers is known throughout the cycle.

Current state

(BTC Blocks) |----Prepare (80)----|----Handoff (20)----|-----Reward(2000)----|

Proposed update

|------- DKG (80) --------|-----Handoff (20) --------|------Reward(2000)---|

Definition of done:

The docs specify PoX phases which distinguish DKG from Handoff.

Open question. In Nakamoto consensus, signers will be running DKG as part of consensus. Could we completely avoid the DKG phase?
