Similar to POI, the PoD selects the accounts with high influence. All accounts are ranked according to their liquidity and propagation (Nebulas Rank).
Top-ranked accounts are selected
Chosen accounts pay deposit and are qualified as the blocks Validators (Validators Set is dynamic, changes in Set may occur after Epoch change.)
Algorithm pseudo-randomly chooses block Proposer
After a new block is proposed, Validators Set (each Validator is charged a deposit) participate in a round of BFT-Style voting to verify block (1. Prepare stage -> 2. Commit Stage. Validators should have > 2/3 of total deposits to validate Block)
Block is added. Block rewards : each Validator rewarded with 1 NAS.
