ePrint Report: Rollerblade: Replicated Distributed Protocol Emulation on Top of Ledgers

Dionysis Zindros, Apostolos Tzinas, David Tse

We observe that most fixed-party distributed protocols can be rewritten by replacing a party with a ledger (such as a blockchain system) and the authenticated channel communication between parties with cross-chain relayers. This transform is useful because blockchain systems are always online and have battle-tested security assumptions. We provide a definitional framework that captures this analogy. We model the transform formally, and posit …
