Hashing It Out #6: Stuart Popejoy

ABOUT THIS EPISODE

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 #34: Storj - Shawn Wilkinson & JT Olio

File storage has long been known as a centralized solution. Storj seeks to change this with their decentralized file storage and retrieval architecture. We'll go over their design, engineering goals, and challenges. We dive deep into how erasure codes can be used to mitigate replication requirements, how trust is managed on their decentralized platform, and how one can be incentivized to donate their storage space and bandwidth to the world through their network.

Hashing It Out #33: Loom Network / Plasma Cash - Georgios Konstantopoulos

Plasma is one of the strongest candidates for Layer 2 scaling solutions. Since the Plasma whitepaper was released in August 2017, there's been a multitude of Plasma implementations experimenting with the idea. On this episode we feature Georgios Kosntantoploulos, Lead Researcher at Loom Network, to talk about Plasma, the different variations, and the future of scaling through Layer 2 solutions.

Hashing It Out #32: Grid+ - Alex Miller & Karl Kreder

Grid+ is one of the most legitimate and exciting products utilizing blockchain in the space, so we're very excited to present Alex Miller (CTO) and Karl Kreder (VP Hardware) on our program. We discuss their line of blockchain appliances, how they're built, their design philosophies, and the challenges in building hardware for blockchains. We get to hear some of their thoughts on the future of blockchain and consensus protocols, and where they see the world moving into the future as decentralization becomes and adopted norm.

Hashing It Out #31: Pokt Network - Michael O'Rourke & Luis C. de Leon

This episode features Michael O'Rourke (CEO) and Luis C. de Leon (CTO) of Pocket. Pocket is a chain-agnostic decentralized AWS for blockchain full nodes. In a world where full nodes become more expensive to run, Pokt aims to have people host their nodes in their network by registering it with their Proof of Stake blockchain. Using Pokt tokens, someone can rent usage of the full node, using the node's stake as a guarantee of availability, removing the concern of maintaining one's own hardware (virtual or otherwise) to create a decentralized application.
