摘要

The rapid development of 6G networks is transforming the traditional mobile network service model from operator-centric to a more open and collaborative ecosystem. As 6G aims to support a vast number of connected devices and diverse applications, efficient trust management, robust security, and streamlined fee settlement are crucial. Blockchain technology offers a promising solution with its decentralized and tamper-resistant features. However, the challenge of balancing decentralization, scalability, and security, known as the “Impossible Triangle,” hinders its seamless integration into 6G networks. To overcome this, we present a self-evolving high-performance sharded consortium blockchain (EvoChain) designed for 6G networks. EvoChain utilizes subjective logic scoring and a multi-agent Stackelberg game concepts for autonomous blockchain evolution. Through sharding, EvoChain partitions the network into manageable subsets, enabling concurrent transaction processing and improved scalability. Extensive simulations show that EvoChain outperforms existing solutions like Elastico and OmniLedger, with 1.28–3.06 times higher scalability and 1.46–3.35 times higher security scores.
