Hashing It Out #23: Avalanche - Emin Gün Sirer

ABOUT THIS EPISODE

Revolutionary! On this episode we have the brilliant Dr. Gün Sirer to whet our appetites for Avalanche, a new category of consensus protocol. He distinguishes Avalanche from Paxos/RAFT systems, blockchain, and traditional gossip networks to show how this new algorithm prevents double spends while allowing for high throughput (early tests supporting over 1200 tx/s). We learn about his new coin, Ava, which will test the limits of Avalanche's public consensus on a global scale! The future is exciting!

Hashing It Out #35: Constantinople Postponement - Trail of Bits & ChainSecurity

Back with season 2 of Hashing It Out, and we have a doozy! This Episode features Trail of Bits and ChainSecurity to talk about their amazing last-minute catch of EIP-1283's impact on the Constantinople Ethereum hard fork. We go over how they found it, what recommendations they made, and how the hard fork was postponed to quickly. We also discuss the tooling behind analyzing such a vulnerability, the true impact had it been released, and how the processes around hard fork release candidates could be altered by this detection.

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.
