Abstract :
Present indirect contribution transaction protocols are vulnerable to sybil attacks where one or more attackers can forge a large number of fictitious nodes. In this paper, we propose a decentralized sybil-resilient contribution transaction protocol. It allows nodes to obtain service for use from remote nodes, while restricting the amount of service which sybil nodes receive from honest nodes even in the face of a large number of attack edges. We verify this property by running it on random graphs with different lengths of contribution transaction chains.
