Hashing It Out #12: Full Casper Chain v2 - Casper + Sharding Jun 19, 2018

Show notes

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 Jun 14, 2018

Show notes

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 Jun 09, 2018

Show notes

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 Jun 08, 2018

Show notes

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 Jun 07, 2018

Show notes

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.

Hashing It Out #7: MIMIR Blockchain Solutions May 15, 2018

Show notes

On this stupendous episode of Hashing It Out, we touch base with Hunter Prendergast and Forrest Marshall of MIMIR Blockchain Solutions about the technology behind their multi-chain blockchain service provider system. They discuss some of the economics behind developing their staking mechanism for ensuring trust in their network. We get into some of the challenges their system is tackling and it's unique approach which sets it apart from Layer 2 scaling solutions that exist.

Hashing It Out #6: Stuart Popejoy May 08, 2018

Show notes

This week's episode features Stuart Popejoy, founder of the Kadena, creator of the Pact smart contract language, and engineer/designer of the Chainweb blockchain protocol. We go in-depth on design decisions for Pact, how language simplicity impacts the security and adoption of second generation blockchains, how formal verification can be used to improve certainty in smart contracts, and the over-emphasis of Turing completeness for a very domain-specific language such as smart contracts. We go into the design behind Chainweb, an unboundedly scalable Proof of Work blockchain architecture, which expects to reach a whopping 10,000 tx/sec (864,000,000 tx/day) on its first year of release.

Hashing It Out #5: Zaki Manian May 02, 2018

Show notes

We had the pleasure of interviewing Zaki Manian, prolific engineer, Founder of SkuChain, Head of Tendermint Labs, Advisor on the Interchain Foundation, and Executive Directory of the Trusted IoT Alliance. Phew, that's a lot of hats. Zaki gives us a glimpse into what it's like designing a scalable, secure consensus protocol. We speak to him about the philosophy behind scaling solutions, the differences in approach to consensus mechanisms, the role of blockchain as the world grows accustom to trust, and get a really solid look into the history of the blockchain space that led to where we are today.

Hashing It Out #4: William O'Beirne Apr 24, 2018

Show notes

Will O'Beirne of MyCrypto talks with us about front end dapp development, conveying trust to your end-user on trustless networks, deployment methodology for decentralized systems, and what it takes to build a product in this early stage of blockchain development. We also go over some of the project libraries and tools used in creating MyCrypto. It's a compelling take on how UX design can inform product growth.

Hashing It Out #3: Fabian Vogelsteller Apr 17, 2018

Show notes

Fabian Vogelsteller, creator of the Mist wallet, Web3.js, the history of the ERC20 Token standard, and his ERC725 Identity proposal. He speaks to us about his new industry effort, Lukso (https://www.lukso.io/), which marries blockchain to luxury goods supply chain solutions. He speaks to us about adoption, data governance, industry network effects, and how to bring enterprises to blockchain. We get into his thoughts on standardization to build open communication protocols for building bridges between collaborators, regulators, and end consumers to ensure data integrity. We speak to him about the impact of the ERC20 standard proposal and how it has fostered a $6 billion ecosystem.
