Hashing It Out #12: Full Casper Chain v2 - Casper + Sharding

ABOUT THIS EPISODE

A set of notes were just released for a revised version of the Casper protocol which merges its goals with sharding research. It uses a beacon chain to behave as a source of randomness with the RANDAO being central to that chain. This enables a commitee of validators to be selected for validating individual shards rather than the entire chain and sign it using BLS signatures. Corey Petty and Collin Cusce discuss these notes and try to suss out what this means for Ethereum if it were implemented.

Hashing It Out #11: NuCypher - John "Tux" Pacific & David Nunez

In this episode, we dive into NuCypher. NuCypher is an encryption library for managing key access on decentralized networks. We talk about proxy re-encryption, how access is granted, and the creation of their node network. We also discuss the topic of fully homomorphic encryption and the role of privacy in future decentralized applications.

Hashing It Out #10: TrueBit - Harley Swick

TrueBit is one of the more impressive decentralized projects, and we're really excited to have had the chance to interview Harley Swick, core developer on the project. We talk to him about TrueBit, how it works, it's significance, how it differentiates itself from other off-chain computation projects. We go over some of the many, many applications of decentralized off-chain computation projects and how they can improve world resource utilization. Amazing and really exciting stuff!

Hashing It Out #9: Rick Dudley

The prodigious Rick Dudley talks with us about his work as a consensus subject matter expert. He lends us his experience and wisdom in consulting for the creation of Byzantine Fault Tolerant systems. We also delve into what it takes to build a completely decentralized public data storage system and why it's such a difficult problem.

Hashing It Out #8: Mahnush Movahedi

We talk with Mahnush Movahedi of DFINITY to explain the fundamental innovation behind DFINITY's consensus system. She explains how threshold relay works, how groups are determined in consensus, and how cryptographic deterministic randomness drive consensus as a fast and light-weight substitute for Proof of Work. We learn about how this impacts the architecture for state and network protocol design. This episode really shows why Mahnush, a PhD Yale postdoctoral computer scientist with a focus on multiparty computation, would choose DFINITY as the project to join to innovate on consensus protocols.
