Proof-of-Social-Capital: A Consensus Protocol Replacing Stake for Social Capital
For blockchain researchers and developers, this work offers a new paradigm for consensus that leverages social interactions, though it is theoretical and lacks empirical validation.
The paper proposes a novel consensus protocol that replaces financial stake with social capital (trust and influence from social interactions) to improve fairness and decentralization in blockchains. The theoretical framework integrates zero-knowledge proofs and verifiable credentials, but unresolved issues like off-chain bribery remain.
Consensus protocols used today in blockchains often rely on computational power or financial stakes - scarce resources. We propose a novel protocol using social capital - trust and influence from social interactions - as a non-transferable staking mechanism to ensure fairness and decentralization. The methodology integrates zero-knowledge proofs, verifiable credentials, a Whisk-like leader election, and an incentive scheme to prevent Sybil attacks and encourage engagement. The theoretical framework would enhance privacy and equity, though unresolved issues like off-chain bribery require further research. This work offers a new model aligned with modern social media behavior and lifestyle, with applications in finance, providing a practical insight for decentralized system development.
