Mir-BFT: Scalable and robust BFT for decentralized networks
This paper presents Mir-BFT, a robust Byzantine fault-tolerant (BFT) total order broadcast protocol aimed at maximizing throughput on wide-area networks (WANs), targeting deployments in decentralized networks, such as permissioned and Proof-of-Stake permissionless blockchain systems.

State machine replication scalability made simple
Consensus, state machine replication (SMR) and total order broadcast (TOB) protocols are notorious for being poorly scalable with the number of participating nodes. Despite the recent race to reduce overall message complexity of leader-driven SMR/TOB protocols, scalability remains poor and the throughput is typically inversely proportional to the number of nodes.

IPC subnets land on Filecoin Spacenet
The Interplanetary Consensus framework (IPC), formerly known as Hierarchical Consensus, addresses two challenges of blockchain networks, transaction volume and application heterogeneity. In doing so, it boosts the capabilities of the Filecoin network.
