| 요약 | As distributed systems become more federated and cross-domain, we are forced to rethink some of our core abstractions. We need heterogeneous systems with rigorous consistency and self-authentication guarantees, despite a complex landscape of security and failure tolerance assumptions. I have designed, built, and evaluated heterogeneous distributed algorithms with broad applications from medical privacy to blockchains.This dissertation examines three novel building blocks for this vision.First, I show that serializable transactions cannot always be securely scheduled when data has different levels of confidentiality. I have identified a useful subset of transactions that can always be securely scheduled, and built a system to check and execute them.Second, I present Charlotte, a heterogeneous system that supports composable Authenticated Distributed Data Structures (like Git, PKIs, or Bitcoin). I show that Charlotte produces significant performance improvements compared to a single, universally trusted blockchain.Finally, I develop a rigorous generalization of the consensus problem, and present the first distributed consensus which tolerates heterogeneous failures, heterogeneous participants, and heterogeneous observers. With this consensus, cross-domain systems can maintain ADDSs, or schedule transactions, without the expensive overhead that comes from tolerating the sum of everyone's fears. |
