DKGSet will run several tasks during a round (or epoch described in DEXON Consensus Algorithm).

Suppose the interval [0, T) and [T, 2T) are round r and r+1, respectively. (T is the round interval defined in Governance Contract)

The time t is the Consensus Timestamp of the delivered block.

@ t = T/2

DKGSet_r starts the TSIG protocol to generate CRS_r+1 = TSIG(CRS_r). DKGSet_r+1 is then decided.
After DKGSet_r+1 is decided, DKGSet_r+1 register their DKG ID. (Phase 1 of DKG + TSIG Protocol)

@ t = T * 2 / 3

DKGSet_r+1 starts the DKG protocol (Phase 2 of DKG + TSIG Protocol)

@ t = [T, 2T)

DKGSet_r+1 calculate the Block.Randomness = TSIG(Block.Hash) using TSIG protocol for each block confirmed in the round r+1. (On Chain Random Oracle)

Special Case for Round 0

CRS_0 is defined in Genesis state.
No DKGSet and Block.Randomness.
CRS_1 = HASH(CRS_0)
