最新报道:Bitcoin advocates highlight concerns over proof-of-stake (PoS) systems potentially creating an "oligarchy" of large validators, as knowledge proofs emerge as a possible alternative. Critics argue PoS favors wealthy participants who can afford significant stakes, centralizing control. Researchers suggest zero-knowledge proofs (ZKPs) could decentralize validation by allowing smaller participants to verify transactions without high capital requirements. Ethereum's shift to PoS has intensified debates over blockchain governance models, with Bitcoin remaining committed to proof-of-work (PoW) for its perceived neutrality. The discussion reflects broader tensions in crypto between scalability, security, and decentralization priorities.
