OrderlessChain
Pezhman Nasirifard, Ruben Mayer, Hans‐Arno Jacobsen · 2022
Blockchains often use coordination-based consensus protocols to offer trust in a Byzantine environment and to serialize transactions to preserve the application's invariants. However, coordination can be a performance bottleneck. There exist application-level invariants known as Invariant-Confluence (I-confluence), which can be preserved without coordination and benefit from improved performance. We introduce OrderlessChain, a coordination-free permissioned blockchain for the safe execution of I-confluent applications.
