Cryptography-Based Bootstrapping Scheme for Permissionless Sharding Blockchain
Ziqiang Xu, S. Ahmad Salehi, Naveen Chilamkurti · 2024
This paper proposes a secured bootstrapping protocol based on BLS aggregated signatures. The protocol provides a secure, efficient identity endorsement and verification scheme for permissionless sharding blockchain and effectively prevents the Sybil attack during the bootstrapping process. Our results show that our scheme is secure and supports large-scale networks. Our scheme performs better than the current methods in preventing the Sybil attack.
