The rise of centralized mining pools for risk sharing does not necessarily undermine the decentralization required for permissionless blockchains: Each individual miner's cross-pool diversification and endogenous fees charged by pools generally sustain decentralization, because larger pools...

Blockchain technology provides decentralized consensus and potentially enlarges the contracting space through smart contracts with tamper-proofness and algorithmic executions. Meanwhile, generating decentralized consensus entails distributing information that necessarily alters the informational...

We model platform competition with network effects, infrastructure investment, and data collection and sharing, thereby providing a unifying framework to evaluate data-related regulation and antitrust policies. Data feedback improves service quality but may concentrate market power. Dispersed...
