CrustChain: Resolving the blockchain trilemma via decentralized storage and proof-of-capacity consensus.

ABSTRACT: The blockchain trilemma-achieving scalability, security, and decentralization simultaneously-remains an unsolved challenge in distributed systems. This paper introduces CrustChain, a novel framework that advances decentralized storage and consensus via three key innovations: (1) a reputation-weighted (where node influence scales with storage contribution and historical reliability) Proof-of-Capacity mechanism with temporal Sealed-Post (SPoSt) challenges, (2) hybrid erasure-network coding for 82% storage cost reduction, and (3) MDP-optimized sharding for sub-second cross-shard latency. By combining storage resource guarantees with a sharded validation layer, CrustChain processes 1,450 transactions per second (TPS) at sub-second latency while maintaining a chain quality score (fraction of bl
