Finding Nemo-Nemo: CFT DAG-based Consensus in the WAN
Rithwik Kerur, Pasindu Tennage, Philipp Jovanovic +3
This paper introduces Nemo-Nemo, a practical crash-fault tolerant (CFT) consensus protocol designed to outperform existing protocols in wide-area networks by bridging design princi…
Towards the ideals of Self-Recovery and Metadata Privacy in Social Vault Recovery
Shailesh Mishra, Simone Colombo, Pasindu Tennage +2
Social key recovery mechanisms enable users to recover their vaults with the help of trusted contacts, or trustees, avoiding the need for a single point of trust or memorizing comp…
Mahi-Mahi: Low-Latency Asynchronous BFT DAG-Based Consensus
Philipp Jovanovic, Lefteris Kokoris Kogias, Bryan Kumara +3
We present Mahi-Mahi, the first asynchronous BFT consensus protocol that achieves sub-second latency in the WAN while processing over 100,000 transactions per second. We accomplish…
Mandator and Sporades: Robust Wide-Area Consensus with Efficient Request Dissemination
Pasindu Tennage, Antoine Desjardins, Eleftherios Kokoris Kogias
Consensus algorithms are deployed in the wide area to achieve high availability for geographically replicated applications. Wide-area consensus is challenging due to two main reaso…
