DRPoS Consensus Algorithm
Overview
MIRENA adopts Delegated Random Proof-of-Stake (DRPoS), where 17 elected Block Producers (BP) and 6 randomly selected Block Observers (BO) participate in each round to generate blocks in a randomized order.
This model reduces excessive resource costs, while ensuring integrity by allowing random nodes to monitor and validate the elected producers.
DRPoS enhances all three elements of the blockchain trilemma — security, scalability, and decentralization — addressing the limitations of traditional PoW and PoS models.
The block production structure is optimized for 3-second block times, with 23 nodes (17 BPs + 6 BOs) creating blocks every round.
This fixed group structure enables finality within just 51 seconds, with minimal overhead compared to traditional hash-based methods, resulting in superior verification speed and bandwidth efficiency.
