Marley Gray: Project Bletchley – Microsoft’s Blockchain 3.0 Architecture
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 covered 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

Mona El Isa & Reto Trinkler: The Polkadot Protocol – One Blockchain to Connect Them All
System scalability and extensibility of system features are two central problems around which research in the cryptocurrency / blockchain industry has centered. For example, the Blockstream sidechains project foresaw hundreds of blockchains coordinating together to form an ‘Internet of Chains’ delivering extensibility to the Bitcoin system.
Recently, Dr. Gavin Wood, co-founder of Ethereum and Parity, put forth Polkadot, a technical vision to achieve the similar end-goals using different system architecture. Polkadot could enable individual blockchain networks to share security and communications infrastructure with other blockchain networks, forming in effect an ‘Internet of Blockchain networks’.
Melonport, a team based out of Zurich, has taken up the challenge of deploying the Polkadot network and also building decentralized asset management software on the same network. In this episode we converse with Mona El Isa and Reto Trinkler, co-founders of Melonport, in order to discover more about the overall vision.

Leanne Kemp: Everledger – Detecting Diamond Fraud and Theft
As is the case with most luxury goods, the diamond industry is faced with the issues of theft, fraud, and counterfeiting. Illegal activity is present at every level of the supply chain, which collectively costs the industry and its insurers hundreds of millions of dollars each year. In recent years, international treaties and regulation have been put in place in an attempt to combat illegal activity, but criminals are most often a step ahead.
Leanne Kemp, CEO of Everledger, joins us to explain how her company is using advanced geological techniques, and blockchains, to bring more traceability to the diamond industry. Everledger, whose clients include many of the largest insurance companies, builds software which allows for a diamond’s unique characteristics to be hashed and notarized in the blockchain. Hence, a stone’s provenance, and the trail of ownership can be traced, therefore limiting the opportunities for fraud and making it difficult for stolen diamonds to re-enter the market.
Topics covered in this episode:
Leanne’s background as a technologist
A broad overview of the diamond industry
A look at the diamond supply chain
What roles banks and insurance companies play in the supply chain
How diamonds are uniquely fingerprinted
The Kimberly process and other regulations
Everledger’s technology stack and business model
Other sectors which can also benefit from increased traceability

Mike Hearn & Richard Gendal Brown: Corda – A Distributed Ledger for Financial Services
Attracting over 70 of the world’s biggest financial institutions to its consortium in just over a year, R3 has accomplished a formidable task. Aiming to rethink the fabric of the financial system, they first conducted experiments testing blockchain platforms for their member and last year began developing their own distributed ledger platform: Corda.
The effort to build Corda was lead by R3 CTO Richard Brown and the former Bitcoin developer and R3 lead architect Mike Hearn. In a wide-ranging discussion, we covered the vision of the project and why it represents a radical departure from existing blockchain platforms.
Topics covered in this episode:
The origin story of R3
Why existing blockchain designs didn’t meet their needs
How the R3 team lead a design effort to develop a new platform from scratch

Greg Meredith: Synereo – Rebuilding the Attention Economy from the Ground Up
As content becomes more and more abundant and immediately available at our fingertips, our limited attention is a barrier for those whose business it is to attract and harness it. In this context, large (social) media companies understand that attention is a scarce commodity, and, as has been demonstrated, those who control attention wield enormous power over our society.
We’re joined by Greg Meredith, CTO of Synereo, to talk about how this new Blockchain platform rebuild the attention economy. In a sense, Synereo is to attention, what Bitcoin is to money, in effect, removing intermediaries from the transaction between those who have attention, and those who wish to attract it. Greg, also gives his insights on how functional programming languages could allow for verifiable computational smart contracts.
Topics covered in this episode:
Greg’s background as a mathematician and his work on Microsoft’s BizTalk Process Orchestration
How he transitioned into the crypto-currency space
What is Synereo and what the project is trying to achieve
Greg’s thoughts on the attention economy and how it is fundamentally broken
Synereo’s technology stack
How Vlad Zamfir’s Casper consensus algorithm influenced Synereo
Rholang, Synereo’s functional smart-contracting language
Synereo’s economic model and product roadmap

Alex Wearn: Decentralized Capital and Government Currencies on Ethereum
A topic which is often discussed is the limited use of Ethereum applications without stable cryptocurrencies. Prediction markets are a prime example of this. When one makes a prediction using Ether, he or she is in fact entering into to speculations: one being the outcome of the actual prediction, the other being the price of Ether when the prediction resolves. Projects like Maker DAO try to solve the problem by developing complex systems to ensure that a blockchain token keeps its value in sync with fiat currencies. But Decentralized Capital is taking a different approach by issuing fiat-pegged tokens on Ethereum that are backed by bank deposits. CEO Alex Wearn joined us to explain their approach to providing a fundamental piece of Ethereum infrastructure.
Topics covered in this episode:
The problem Decentralized Capital is trying to solve
What the architecture of Decentralized Capital looks like
The relationship between Crypto Capital and Decentralized Capital
Why the ability of freezing and confiscating assets is required
Some of the best use cases for Decentralized Capital
The regulatory environment of Decentralized Capital
