Hashing It Out #42 - Monero Research Lab - Brandon Goodell Apr 26, 2019

Show notes

We shouldn't pick favorites, but this is definitely one of our favorite episodes so far. We have the extreme pleasure of learning from Brandon Goodell, Research Associate at Monero Research Lab, about Monero, how it's designed, privacy in Monero and how it compares to other coins like ZCash, scalability, and consensus mechanisms in general. This is exactly the kinda conversations we built this show for, and there were more than one eye opening moments. Definitely scope this one out!

Hashing It Out #41 - MyCrypto - Harry Denley Apr 04, 2019

Show notes

Ahoy-hoy! Today we have Director of Security at MyCrypto, Harry . We talk about phishing attacks! No, not assaults at jam band concerts, the kind where you lose your money. We go over the process of finding these attacks, reacting to them, and staying ahead of the scammers. We talk about the tools used to intercept and analyze these attacks, and the processes surrounding gathering the evidence against the attackers. Harry is doing amazing work, and he's really putting effort into keeping us all safe. Thanks, Harry!

Hashing It Out #40 - Liam Horne - L4 Mar 29, 2019

Show notes

Liam Horne is a developer, decentralization expert, and an open source entrepreneur with a focus on state channels. L4 and Counterfactual have released a new development playground that lets software engineers learn and play with state channels right from their browser. Liam gives us insights on what it's taken to get to this point, where the state of state channel development is right now, and where we're going with layer 2 solutions for scaling blockchains.

Hashing It Out #37 - Base Zero - Matt Zimmerman and Ken Sedgwick Mar 09, 2019

Show notes

Managing crypto keys is difficult enough for private holders, but when managing large portfolios of cryptocurrency assets on an institutional level, the risk surface increases tremendously. Base Zero has devised a suite of tools to manage multisignature signing over an air-gapped signing device and a sharded backup system to ensure security for large organizations. This unique approach enables these institutions to mitigate risk associated with large fund transfers without any one single person being able to compromise the system and with highly secured disaster recovery.

Hashing It Out #36: Dan Robinson - HTLCs (And why they suck) Feb 13, 2019

Show notes

We have the pleasure to present one of the more entertaining speakers at SBC19, Dan Robinson. After two talks on Hash Time Locked Contracts (HTLCs), he drops a massive bomb in with a slide deck entitled, "HTLCs (And why they suck)." Lively and entertaining, we have him step through is thoughts on HTLCs and the alternate solutions to this technique that Interleger implements. Bombastic show chocked full information and analysis!

Hashing It Out #35: Constantinople Postponement - Trail of Bits & ChainSecurity Jan 19, 2019

Show notes

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 Dec 19, 2018

Show notes

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.

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.
