A Deep Dive into Mysticeti: The New Consensus Powering Sui

Written by Fieldlnwza007, infographics by EarthMysticetiIn July, Sui announced a shift from using Narwhal and Bullshark as their consensus protocol to Mysticeti[1]. In this article, I will do my best to simplify the Mysticeti paper and explain how Mysticeti works and why it was chosen from my perspective, while preserving the core ideas.Narwhal and Bullshark RecapTo understand the need for Mysticeti, let’s first review Narwhal and Bullshark. If you’re familiar with these protocols, feel free ...

Celestia: A Summary of How Fraud Proofs and Data Availability Proofs Work

1 OverviewData availability (DA) is crucial to the functionality and security of blockchains. In traditional monolithic blockchain structures, full nodes retrieve blocks from peers to verify the integrity of the entire history of their chain based on predefined rules. This process relies on the assumption that data on the blockchain remains consistently "available" for access by all nodes in the network. This principle holds not just for layer-1 blockchains but also for layer-2 blockchains, w...

Introduction to Walrus: A Note on How the Red Stuff Protocol Works

1. IntroductionSo far, we’ve discussed two decentralized storage networks: Celestia [1] and Espresso [2]. Unlike traditional decentralized storage systems that rely on full replication, where every node stores a complete copy of the original data, Celestia and Espresso use erasure coding. This method splits data into encoded fragments, allowing reconstruction from only a subset of these fragments. By requiring nodes to store only a small fraction of the encoded data (much smaller than the ful...
