'œBitcoin is the culmination of 30 years of attempts at building digital money for the internet.' '" Matt Corallo

Interview location: London

Interview date: Thursday 7th Feb, 2019

Company: Chaincode Labs

Role: CEO

What is Bitcoin? Is it digital gold? Is it money?

Whoever I put this question to, the answer always changes but one thing that is consistent is that it always retains to technology and value. Perhaps Bitcoin is therefore many things which come together to create a new type of financial infrastructure.

In this episode, I talk with Bitcoin Core developer, Matt Corallo. We discuss what makes Bitcoin work, covering topics such as the Lightning Network, fungibility and inflation. We also talk about issues important to Matt such as BetterHash and adoption.

The Third Web #16 - Urbit, Your New Server
The range of third-web platforms in development today is greater than ever. From data-centric blockchain based approaches to agent-centric designs like Secure Scuttlebut, the potential futures of the third web are rapidly expanding. Today we look at another approach with the Urbit platform. Like Secure Scuttlebutt, Urbit is agent centric. It is a deterministic operating system designed to be the filter between a user and the online services they use. I last covered Urbit in 2016 and the project is now nearing public launch. Galen Wolf-Pauly explains.What is Urbit?A personal ServerA secure computer that you actually ownStores an event log of everything that has ever happened to itThat's designed to live on any cloud serverBut be controlled by a private key that you actually ownYour Urbit is meant to replace all of the consumer cloud software that you already useHow can it possibly be better than all of the expensive software that has already been created?The basic thesis is that everything we use today runs on top of a unix of some kind.The reason we wound up in this centralised world of cloud-based software is that Unix is too complicated.Because the Unix is complicated, complicated layers between Unix and the application are needed.The Urbit solution is to rip all of that out and create a single, extremely simple, complex system.Urbit is a virtual machine, programming language, and operating system in 30,000 lines of code.For comparison, Wordpress, an application that runs on Unix is 500,000 lines of codeTechnical simplicity should turn into user interface simplicity.Additionally, by hosting your Urbit in the cloud you no longer have a middleman serving you applications, Instead you only need them to host your virtual computer. What does an Urbit future look like?A single platform allows tighter integration of, for example, productivity software like Git & Asana.As a designer, Galen looks forward to interface standardisation, -having messaging, documenting, code collaboration, task management and other consumer software working seamlessly as one system.Rather than interfaces built for many people.Do we need a new back end for a new front end? Hasn't Wechat done this?Today we use many services that have unified UIsGoogle has both email and documents but do you really trust Google to have total control and visibility into your use of those services?What if Google goes away?Being able to run a server myself that I trust will be around a long time and is secure to me makes me feel alot better. [Platform Risk]Wechat is a really great achievementApps are more like modulesBut you have given total power to a single companyThe decentralised Wechat pitch has gotten tired but Urbit is very much targeting that problem.The future of cloud computing does look like that but makes no compromises in privacy or durability.So is your vision as a designer that an individual defines their interface standard and that the applications automatically conform to that individual standard?Yes, instead of going to facebook, twitter, Google Docs, etc. and having them deliver the interface to me it is much more like installing a desktop application.In a desktop application scenario most applications make use of common interface elements because it makes more sense to the userYour computing environment should feel like your physical environment. Individuals have different preferences with regard to furnishing and it is relatively easy to pick from different modules of furniture or colours of walls. These are decisions of the size that we are comfortable making. Contrast this to computing interfaces which are like a prefab trailer, or hotel room that you wind up living in the whole time but have no power to customise, only choose between. The alternative is being a Linux SysAdmin who builds their entire interface home themselves. That tradeoff is as unfair and unrealistic as everyone physically building their own homes from scratch.To clarify, it is people working on Urbit full time who would be the ones building interfaces but those interfaces would be able to be applied to all of the applications that run on Urbit, and tweaks to those interfaces would affect all apps.Moving on from the interface. What is the advantage over existing cloud platforms? How is it possible to build something from scratch that is easier to use than the systems that have been developed by hundreds of thousands of people over the course of 30 years?Firstly, Urbit runs on Unix, the internet, TCP/IP, UDP We take the existing infrastructure and build a new layer on top.We are antagonistic toward the existing web stackUrbit is designed for an individual to useYou can think of Urbit as a personal blockchain or a 100 year computer - something that has never existed.Who is the target user?The gold standard is 'œWould I recommend this to my Mom?'More than just the technical community is interested in online privacy and security.The question is more like 'œWould I send an Urbit to my cousin?'This year your friend will be able to acquire an Urbit address and use it to chat with others and make the decision for themselves.Urbit is most interesting to somewhat technical people who are interested in unusual system software. It is also populated by small interesting micro-communitiesThe Urbit testnet has been live since 2013Does Urbit have enterprise applications?In the world of agriculture you cannot customise the software that runs in the machinery commonly available.You can't customise the software inside a Nest IoT device. You cant even connect it to a different server.Urbit operates on it's own network of devices.It is ideal for industrial IoT and can communicate on a local network.Currently data from these devices is collected and stored by third parties who represent a risk of abuse or leaks. Let's take a look at how it works, the networking and application stack.3 main components:Azimuth - the identity system. A series of Ethereum contracts. An Azimuth point is like a combination between a domain name, an email address and an IP address. There is a finite address space and each address is represented as a pronounceable phrase. In total there are ~4 billion user addresses. These addresses are divided hierarchically and have different uses in mind: 264 'œMoons' (devices), 232 'œPlanets' (user addresses), 216 'œStars' (routing nodes), 28 'œGalaxies' (protocol governors).Arvo - the Urbit OS. Very clean separation from external identity system on Ethereum, connected by a common key pair. The Arvo OS has a file system, a system for building applications, a webserver, a networking protocol which is routed over UDP, a vault for secrets or keychain, and a build system. These aree individual kernel modules that provide things from the web stack. A core kernel manages the interactions between these components. The OS is written in a custom language called Hoon which compiles to the Urbit assembly language called Nock. The result is a single deterministic function that Urbit executes every time it gets an event.Aegean?Who makes money from Urbit?Employees of the Tlon company that is developing Urbit, in the form of wages.Holders of Azimuth address space.Providers of Urbit hosting & application development services Recently, Curtis Yarvin, the founder of the Urbit project, left. Is it true that he gave all of his address space to Tlon?NoCurtis Yarvin signed over the the Galaxy addresses he held to Tlon. He retained the control of the stars.Future & FearsThe biggest threat to Urbit is success. If it begins to succeed as an alternative computing model, its possible that large players will attempt to build products that solve the same problems.Urbit's goal is not to be a single network, but rather a network of networks.It takes granular tools to map the way people interact in a computing environment and Urbit aims to make the many different permutations of human communication representable.
The Tatiana Show Ep. 178 Caleb Slade of Salt
Caleb and Tatiana have hung out at several conferences before, and she's been a big supporter of the SALT team early on. However, at the Miami conference, they were able to get a bit further into exactly what SALT lending has to offer. It appears to be a pretty cool way to leverage your holdings, and it is a US based company, so the stricter laws may be helpful. Who knows? Do your own research, but get a taste of what they have to say on this short but sweet Tatiana Show. About the Guests: Caleb Slade is co-founder and chief knowledge officer at SALT where he is responsible for cultivating and maintaining a strong company culture. He spearheads education and evangelism efforts for SALT and blockchain technology at large, and is also responsible for leveraging insights to explore opportunities for SALT to stay both relevant and innovative. Prior to co-founding, Caleb worked in mobile application development, product design, branding, marketing, customer experience and engagement, and graphic design, as well as loan collateral repossession. Caleb's work in the cryptocurrency and blockchain space for the past three years has allowed him to follow his passion for adapting emerging technologies into simple and impactful products. He holds a bachelor's degree in philosophy from the University of Colorado Denver. If you like this content, please send a tip with BTC to: 1444meJi7YjgQGNg3U8Z6qYZFA5cgz4GmjMore

#278 Daniel Lehnberg & Michael Cordner: Grin - Cypherpunk Mimblewimble
Three years ago, a mysterious txt file signed by a pseudonymous Tom Elvis Jedusor was dropped in the Bitcoin-Wizards IRC channel outlining a proposal called Mimblewimble. It proposed a novel way of combining many ideas from Bitcoin research in order to create a new blockchain protocol that will be highly scalable and increase privacy, while still using the same cryptographic assumptions as Bitcoin. A few months later this project was picked up by another pseudonymous individual who started working on an implementation he called Grin. Grin slowly began to draw attention from the Bitcoin community and got a lot of traction. We join Michael Cordner (Yeastplume) and Daniel Lehnberg, two of the core developers of the Grin blockchain. In this episode we discuss some topics around Grin's cypherpunk origins, privacy and scalability features, no-premine fair start, and interesting monetary policy.Topics discussed in this episode:Origins of the Mimblewimble proposal and the prior work it draws uponAndrew Poelstra's contributions to improving and fixing the original proposalScalability and fast sync times achieved through mimblewimble's UTXO set compressionHow UTXO compression when combined with the Dandellion p2p protocol can increase privacyChanges in user experience from Bitcoin to MimblewimbleBeginning of the Grin project as an implementation of the Mimblewimble protocolComparision to BEAM, a competing Mimblewimble implementationInnovating on fair Proof of Work through dual Cuckoo CycleGrin's Monetary Policy and the Mining Fair StartLinks mentioned in this episode: MimbleWimble OriginAndrew Poelstra's Improved PaperIntroduction to GrinGrin for BitcoinersGrin NewsletterMichael Cordner on TwitterDaniel Lehnberg on TwitterSponsors: Azure: Deploy enterprise-ready consortium blockchain networks that scale in just a few clicksSupport the show, consider donating: BTC: 1CD83r9EzFinDNWwmRW4ssgCbhsM5bxXwg ( 1M4dvWxjL5N9WniNtatKtxW7RcGV73TQTd ( 0x8cdb49ca5103Ce06717C4daBBFD4857183f50935 ( episode is also available on :Epicenter.tvYouTubeSoundcloudWatch or listen, Epicenter is available wherever podcasts are distributed.Epicenter is hosted by Brian Fabian Crain, Sƒbastien Couture, Meher Roy, Sunny Aggarwal & Friederike Ernst.

Proof of Love Ep. 5 Women in Politics
I was blown away by Carey Wedler's talk at the 5th annual Anarchapculo in Mexico. It's a popular topic that people love to speculate on: "Why aren't there more women in the Libertarian movement?" The neat thing about Carey's talk was that she talks a lot about the social programming that I have noticed since I was a kid, especially with the advent of Brittany Spears and other more modern pop stars. This has overflow into politics, and she posits why there may be such a left lean among women. That doesn't mean we all have to be stuck in the left/right paradigm though! We talk about Carey's speech, the way to handle creepers, how to say no and not feel guilty about it, along with conference etiquette in an upbeat convo that hopefully will provide a little insight into the female psyche. About the Guests:Carey Wedler is an activist, journalist, and editor in the freedom community. She began her journey toward anarchism on Youtube, and her videos eventually connected her with Carey's videos and reporting focus on challenging the violence, hypocrisy, and cognitive dissonance of statism and American politics while advocating for peace, liberty, and voluntary solutions to government-created problems, as well as spiritual and emotional healing to sustain free societies. She is also a certified yoga instructor.Do you have a burning question, or a show idea for us?

#277 Amaury Sechet: Bitcoin Cash - Part 2
Amaury Sƒchet is the lead developer of Bitcoin ABC, the largest client for the Bitcoin Cash blockchain. Amaury first got started with Bitcoin in 2010 and closely followed the Bitcoin block size debate as it progressed through the early years of Bitcoin. Predicting the eventual failure of SegWit2x, Amaury was part of the original team that helped coordinate the Bitcoin Cash hard fork, timing it with the activation of SegWit on the main Bitcoin blockchain. We discuss with Amaury the roadmap for Bitcoin Cash, especially with regards to their approach to scalability. We cover many of the novel features the Bitcoin Cash development teams are innovating on such as Canonical Transaction Ordering and Avalanche Pre-Consensus, as well as cover some of the more juicy drama that plagued the Bitcoin Cash community in late 2018, leading to split off of Bitcoin SV.Topics discussed in this episode:Block Size Debates in BitcoinOrigins of Bitcoin Cash and the ForkYear 1 Technical Development of Bitcoin CashBitcoin ABC vs Bitcoin SVFuture RoadmapLinks mentioned in this episode: Bitcoin Cash RoadmapGraphene WhitepaperAvalanche Post-ConsensusThe Case for Canonical Transaction OrderingBitcoin ABC vs Bitcoin SV HashwarBitcoin NG EpisodeEthCC MeetupSponsors: Cosmos: Join the most interoperable ecosystem of connected blockchainsAzure: Deploy enterprise-ready consortium blockchain networks that scale in just a few clicksSupport the show, consider donating: BTC: 1CD83r9EzFinDNWwmRW4ssgCbhsM5bxXwg ( 1M4dvWxjL5N9WniNtatKtxW7RcGV73TQTd ( 0x8cdb49ca5103Ce06717C4daBBFD4857183f50935 ( episode is also available on :Epicenter.tvYouTubeSoundcloudWatch or listen, Epicenter is available wherever podcasts are distributed.Epicenter is hosted by Brian Fabian Crain, Sƒbastien Couture, Meher Roy, Sunny Aggarwal & Friederike Ernst.
