EDPoS Node Negotiation Process
The number of Token votes held by the EDPoS node is used as the
weight of the block, and the fixed block node series is generated by
random number calculation. After the establishment of EDPoS
mechanism, random Numbers are generated through negotiation
between EDPoS nodes. The negotiation process takes place once a
minute, and fair random calculations are made through weighted
verifiable key sharing (VSS) and Byzantine fault tolerance.
Each round of consultation includes the following procedures: 1. Node
registration; 2. Encrypted sharding data distribution;3. Secret Footage
released; 4. Data reconstruction and random beacon calculation.
Before each round of negotiation, each EDPoS super node needs to use
ECC algorithm to generate a set of private keys: {a0,a1...,at-1}, and the
corresponding public key: {A0, A1..., At-1}, satisfies Ai = aiG, (i = 0,1...,t -
1). t is the threshold value of reconstructed data, and the maximum value
of t is 50 according to the effective EDPoS super node.
