ADAP-CBR: An Ageing Demand-Aware Prefilling Compact Block Relay Protocol for Efficient Block Propagation in Bitcoin Blockchain Networks

This research focuses on improving the efficiency of blockchain networks. Currently, blockchains struggle to scale due to inefficient communication between nodes. To address this, a new protocol called Demand-Aware Prefilling Compact Block Relay (DAP-CBR) is developed. DAP-CBR proactively includes relevant transactions in blocks based on node demand, reducing redundant data transmission and accelerating block propagation. Building on this, an Ageing Demand-Aware Prefilling Compact Block Relay (ADAP-CBR) is introduced, which further optimises performance by prioritising transaction types. These advancements contribute to more scalable and efficient blockchain systems, enabling broader adoption and real-world applications.
