Hashing It Out is a podcast which dives into the weeds with tech innovators in blockchain infrastructure and decentralized networks to learn more about what they build and the problems they face head on to overcome.

I appreciate the fact that these guys are explaining some of the complex processes associated with blockchain deployments.

Looking forward to more

I’ve been listening to the Bitcoin Podcast Network for a few months now and really enjoy it. They provide a number of regular programs that center on different topics in the space and most will find something there that they enjoy.

One thing that was missing (until now) is a more in-depth discussion of the development efforts and technology behind these emerging blockchain initiatives.

This podcast is excellent for any casual listener that wants to garner an appreciation or understanding of the technical details behind some of these projects. It is also excellent for anybody who is keen on developing in the space and might not be aware of the languages or utilities currently being employed to address emergent problems. 

This is easily my favorite program now. Well worth a listen!

In this Part 1 of 2 on Maker, we talk about the cryptoeconomics behind creating a stable token pegged to the USD.

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.

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. **Links** https://storj.io/ https://github.com/Storj/

Liam Horne

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.

Brandon Goodell

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! Links  https://www.getmonero.org/resources/research-lab/ https://github.com/b-g-goodell https://monerokon.com/  Sponsorship:Thanks again to Trail of Bits for sponsoring this week's episode.   Go check out their great article on how to safely store cryptocurrency and while you're there, check out all their content on the blog!  Stay safe out there.

Niran Babalola

So you have a decentralize app you want to use... how do you know its smart contracts are safe? That's where Panvala comes in! Using their system you can certify the security and authenticity of your smart contracts and obtain a mark in proof of this certification. On this episode we talk with its co-founder, Niran Babalola, about their smart contract registry and certification system. We learn of its process, development, and larger implications. We learn what it takes to get from zero to one in a project that requires community participation to improve the certification process. Links https://www.panvala.com/ https://twitter.com/niran

Michael O'Rourke

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.
