Abstract

Coded blockchain leverages error correction codes to create coded fragments that are then stored in a distributed manner by nodes. Its primary objective is to reduce the storage requirements of participants or nodes, achieving efficient storage and fault tolerance. However, nodes store arbitrary coded fragments, which leads to high communication cost when a node attempts to decode a block. To this end, this paper proposes a novel reinforcement learning inspired distributed protocol to assign coded fragments to nodes. Specifically, nodes learn to store coded fragments based on a feedback signal that relates to storage of coded fragments and communication cost incurred when a node attempts to decode a block. After convergence, the proposed protocol is compared with existing centralized and distributed blockchain encoding storage methods. The results show that nodes have 7% higher reward, and critically, their communication cost is lower by 55%. In summary, the reinforcement learning-based distributed protocol proposed in this study provides an effective solution for enhancing the storage and transmission performance of encoded blockchains.
