Marley Gray: Project Bletchley - Microsoft's Blockchain 3.0 Architecture (Episode 161)
Support the show, consider donating: 1JqE3eCwn7PeFNZUq6U2LExwxFqGBS9eqM (http://bit.ly/2gl9HIP)
In their relatively short lifespan, blockchain technologies have already undergone significant milestones. Bitcoin’s blockchain, often referred to as Blockchain 1.0, features a simple database ledger that records transactions in a chronological order and represents the state of the network to participants. Ethereum, or Blockchain 2.0, introduced the notion of smart contracts. Microsoft’s Bletchley Project introduces a new modular architecture which might mark a new milestone for blockchain technologies.
Marley Gray, Principal Program Manager Blockchain at Microsoft, joins us to talk about Microsoft’s approach to blockchain architecture. With enterprise in mind, Bletchley introduces the concept of “Cryptlets”, the core building blocks for introducing a secure middleware tier into blockchain application infrastructure. These computational units, running off-chain, on secure trusted container enclave hardware, could provide trusted data to on-chain smart contract logic.
Topics discussed in this episode:
- Marley’s background and experience at Microsoft
- Why Microsoft is aggressively pursuing blockchain technologies (compared to other large tech companies like Amazon, Google, Facebook, etc)
- Microsoft’s Azure Blockchain-as-a-Service offering
- Project Bletchley, its goals and the problems it is trying to address
- The primary use cases in which Bletchley may provide value
- How Bletchley addresses the issue of deploying consortium style blockchains
- What are Cryptlets and how do they relate to Bletchley
- How Cryptlets are different from Oracles
- How Cryptlets could provide data to Ethereum-style smart contracts

What Bitcoin did for money, OpenBazaar is trying to achieve for commerce. Born as a fork of the Dark Market project, OpenBazaar aims to facilitate online trade by removing unneeded middlemen. Built as an open source protocol, users simply install the application on their computer to gain access to marketplaces available on the network. From the app, they may also place items or services for sale by creating ""Ricardian contracts"", which get propagated to the network and made accessible to everyone to see. The protocol, which uses Bitcoin as a means of payments, utilises multi-signature transactions. This makes it possible for transacting parties to include third-party arbitrators, who may intervene in the event of a dispute. We talked to Brian Hoffman, the project's Lead Developer, about this paradigm-shifting project and the potential it has to disrupt person-to-person marketplaces such as eBay. Currently in beta, OpenBazaar is due for a full release in Q1-Q2 of 2015.
Topics we discussed:
- History and current status of the project
- Mechanics of a simple transaction on OpenBazaar
- Ricardian contracts
- OpenBazaar's proposed arbitration model
- Reputation and the important role it plays in peer-to-peer trading
- Business models that may be threatened by this technology

As blockchain technologies mature, new protocol specifications are emerging, which take unique approaches to software design and how consensus is achieved. We have talked about Multchain and OpenChain in the past, but Tendermint promises to be a viable solution for many permissioned blockchain use cases. It’s design is modular, meaning that the application layer (smart contract) and the consensus layer are completely independent. This provides added flexibility and allows for business logic to be written in practically any programming language. In addition, its unique approach to consensus, a round-robin Proof-of-Skate algorithm, is much better suited for permissioned blockchain scenarios than Proof-of-Work.
Meher and Sebastien talk to Tendermint co-founders, Jae Kwon, Dustin Byington and Ethan Buchman, about this promising new blockchain protocol and how it is different from other projects we’ve seen so far.
Topics covered in this episode include:
- How Tendermint came to be and how it has evolved since its creation
- Smart contract programming and the Tendermint Socket Protocol (TMSP)
- How Tendermint makes use of the Ethereum Virtual Machine (EVM)
- Tendermint’s approach to PoS consensus and its scalability benefits
- Use case for permissioned and public blockchains
- Future plans and business models

In the short history of the Bitcoin industry, there has been an impressive amount of high profile hacks, ranging from a few hundred thousand to many millions of dollars. In all of these, customers, Bitcoin users, where robbed of their funds because poor security policies, negligence, incompetence, or plain old scamming. Recently, the cryptocurrency conversion service ShapeShift fell victim to a hack in which over $200,000 of company funds were stolen, initially by an employee, and then by a hacker to whom this employee had sold sensitive company information. Luckily, no customers lost any money as ShapeShift does not hold any funds on behalf of users.
We talked to ShapeShift CEO Erik Voorhees who walks us through this captivating ordeal, which sounds like it could be the plot of a movie. He speaks about how the company is trying to recover and what he has learned from this unfortunate event.
Topics we discussed on this episode:
- How the ShapeShift hack went down
- What steps the company has taken to avoid this from happening again
- What he learned from the hack
- ShapeShift's long-term vision as a company and product
- Ethereum's role in their recent growth
- His history as an entrepreneur in the Bitcoin space
- His views on libertarianism and the long-term impact of Bitcoin on that movement

Many people think of Bitcoin as the ultimate contender against the power of central banks, most importantly the Federal Reserve System. But that is certainly not the only way that cryptocurrencies and the blockchain can be used and one particularly interesting idea is that central banks could issue their own cryptocurrencies.
To discuss how this could be done and what the consequences could be we were joined by David Andolfatto, a Vice President of Research at the Federal Reserve Bank of St. Louis and a professor of Economics at Simon Fraser University.
Topics covered included:
- What makes good money? How does Bitcoin fare in comparison?
- What is Fedcoin and how could it work?
- Why the tension between a governments desire for control and the desires for 'permissionless innovation' could make this difficult to implement
- Whether Fedcoin would threaten fractional reserve banking
- Why competition between currencies, both governmental and non-governmental, could be a good thing

Peter Thiel argued in his book 'Zero to One' that the way to build a great and highly profitable company is to build a monopoly. But with decentralized technologies, there is a real question whether these monopolies can be built or whether the monopolies will end up being publicly owned goods (like Bitcoin) that can't be monetized directly.
William Mougayar, who is an experienced tech executive and angel investor, has been writing extensively about these issues and was one of the investors in OB1, the venture-backed company launched by the founders of the decentralized market place Open Bazaar. He joined us for a discussion of the cryptocurrency space, Ethereum, Open Bazaar and monetizing decentralized technologies.
Topics covered included:
- Bitcoin as the new, thin cloud
- His long-term predictions about where the space is going
- What kind of business models are the most promising
- Why he chose to invest in OB1, the company behind Open Bazaar
- What the state of Venture Capital in the cryptocurrency space is

Many of our viewers may also be following the Chris before coffee show hosted by Chris Ellis. Chris is a passionate entrepreneur focusing on leveraging Bitcoin to improve the lives of content creators.
Here, I catch up with him to talk about his project ProTip and his effort to distribute cheap Bitcoin nodes in the developing world.
ProTip is a cool chrome extension that allows users to donate money to all the content creators whose content they consumed. The extension works in the background, monitors websites visited and then divides an allocated weekly budget of the users to the creators of the websites.
We talked about:
How does ProTip work?
How ProTip solves the problem of high mental cost of monitoring micropayments?
How his solution preserves user privacy and can enable content creators to have better lives.
His new project for spreading cheap bitcoin nodes in developing nations.
Watch the video to discover a very interesting content monetization mechanism and a dynamic crypto-personality.
