Minimizing Mempool Dependency in PoW Mining on Blockchain: A Paradigm Shift with Compressed Block Representation for Enhanced Scalability, Decentralization and Security.

본문 미리보기

While existing Proof-of-Work (PoW) based blockchain protocols have demonstrated innovative potential, they face inherent limitations regarding scalability, efficiency, and decentralization. The compact block propagation method, though effective in reducing network bandwidth and propagation delay in ideal environments, suffers from performance degradation due to mempool inconsistencies among nodes. This paper proposes a novel block propagation and consensus protocol that mitigates the blockchain'
