Improving resistance to Sybil attacks in decentralized networks using the RTCT protocol
This paper proposes Random Time Challenge-Tokens (RTCT) as a mechanism to economically enforce honest participation and deter Sybil attacks at the network level, and shows that RTCT can exponentially increase an attacker’s costs with higher challenge difficulty, making networks more resilient.
