Dark pools have existed for as long as there have been financial markets. Over-the-counter, or OTC markets, are sometimes also referred to as ‘upstairs trading,’ evoking the era when firms and high-net-worth individuals would meet in the upper quarters of financial markets to make large trades privately. A dark pool is a private forum where one has access to high volumes of liquidity outside the boundaries of public markets. Orders and trades represented in dark pools typically remain confidential outside the purview of the general markets, thus preventing undesirable market impact. We’re joined by Taiyang Zhang and Loong Wang, who are respectively CEO and CTO of Republic Protocol. Republic operates as a decentralized dark pool for cryptocurrency trading pairs such as Ether, ERC20 tokens, and Bitcoin. Buy and sell orders remain confidential in a hidden order book until matched without any of the parties having access to the underlying details. Trades are settled using cross-chain atomic swaps without the inte

In just over ten years, geospatial tracking has gone from being a niche technology used by the military and outdoor enthusiasts to mass adoption, available to just about every connected device in existence. GPS and other location-tracking systems not only allows us to find our way and share our location but is critical to businesses and governments. However, while GPS has become a standard thanks to its accuracy and availability, decentralized applications can’t rely on its location data as it can be easily spoofed and lacks reliability. We’re joined by Ryan John King, CEO of FOAM, a blockchain protocol which aims to offer secure location services independent of external centralized sources such as GPS. FOAM introduces a novel crypto-spacial coordinate system that is better suited to blockchains than standard addresses or latitude and longitude coordinates. It also provides a Proof of Location Protocol, which leverages long-range low-power radio networks, and incentive mechanisms, allowing network participant

The healthcare industry is paradoxical. On the one hand, treatment technologies represent some of the most advanced science known to humankind, while some administrative tasks are still performed using paper and fax machine. Studies have shown that the administrative costs of healthcare can represent up to one-third of the total cost of care. Also, as diagnosis, treatment, and care, becomes increasingly data-driven and patient-specific, the industry needs to adopt more secure and robust technologies to manage patient data and communications between the patient and the different participants in the healthcare supply chain. We are joined by John Bass and Corey Todaro, who are respectively CEO and CPO of Hashed Health, an innovation firm focused on accelerating the meaningful development of blockchain and distributed ledger technologies for the industry. Hashed Health works to build solutions which leverage blockchain to solve some of the most important challenges facing this sector. Topics covered in this episo

Over the past year, as cryptocurrencies and ICOs started to go mainstream, we have seen a huge surge in regulatory activities. In the US, many different regulatory bodies including SEC, CFTC and FinCEN stepped forward to regulate crypto projects in different ways. Seemingly contradictory statements have added to confusion and fear of a broad crackdown looming. We were joined by CoinCenter Director of Research Peter Van Valkenburgh to shed clarity on recent developments and understand where things are heading. Topics covered in this episode: The recent congressional hearings about cryptocurrencies and ICOs How the US regulatory environment for cryptocurrencies evolved in the last year Whether overly broad and contradictory regulation is emerging in the US Understanding the difference between CFTC and SEC Why CFTC regulating existing cryptocurrencies and SEC ICOs would be a good outcome Why decentralized exchanges will be a likely target by SEC The recent letter by FinCEN about ICOs and money transmission Comp

According to the World Bank, universal financial access is vital to reducing poverty, and lack of access to credit plays a significant role in widening inequalities between developed and developing nations. For producers at the end of the supply chain, and who typically have little access to capital, waiting for customers to pay for their products puts them at high financial risk and threatens their livelihood. What if there was a way to bring more liquidity to global supply chains, by allowing anyone to create liquidity from their existing assets. We’re joined by Bob Summerwill, Community Ambassador at Sweetbridge, an ambitious project that aims to change the way global business operates at a fundamental level. While supply chains account for about two-thirds of the World’s GDP, value is trapped in non-liquid assets sitting in warehouses, on store shelves, or in the form of outstanding invoices. Sweetbridge acts as a sort of OSI model for global business. In the Sweetbridge economy, working capital is freed

We were joined by Anson Zeall, who is one of the leaders of Singapore’s blockchain and FinTech community.

We’re joined by Jeff Garzik, who was among the very first developers to work with Satoshi in the early days of Bitcoin. Later, he was a core developer at Bitpay and even tried to put a Bitcoin node on a satellite in space. Today, he is co-founder at Bloq, a company providing enterprise-grade blockchain infrastructure. Bloq recently announced a new project called Metronome that challenges some of the design and governance principles of many public blockchain networks. Metronome is cryptocurrency that sits on top of existing blockchains and aims to allow tokens to easily move from one network to the other. A series of standard blockchain contracts allow for daily descending price auctions to occur automatically, and for users to buy and sell the tokens using a Bancor-like system with built-in liquidity. Topics covered in this episode: Jeff’s background as a web developer at CNN and as a Linux developer His early days in Bitcoin working with Satoshi His thoughts on Bitcoin governance and lessons learned from th

That decentralized networks represent a massive investment opportunity is no longer a controversial view. In the last year alone, over 200 funds dedicated to investing in cryptoassets have been created. But the principles and frameworks to understand this new world are still in its infancy. One fund at the forefront of advancing this understanding has been Multicoin Capital. Their Founders Kyle Samani and Tushar Jain joined us to discuss some of the concepts they use to invest in decentralized networks. Topics covered in this episode: Google Glass and the origin story of Multicoin Capital Why the most used smart contract platform will produce the winning store of value Why they are bearish on Bitcoin Why money is best thought of as an adjective not a noun Differentiating between work, payment and burn-and-mint tokens Why work tokens capture network value better than payment tokens The future of Multicoin Episode links: Multicoin Capital Website New Models for Utility Tokens Blockchains: A New Social Order

Decentralized exchanges have been a holy grail in the cryptocurrency space, since at least the MtGox hack. They promise to derisk the act of exchanging cryptocurrency by leaving custody of funds in the hands of the users. And they should be resistant to regulatory pressure, creating a permissionless way to trade cryptocurrencies. Among decentralized exchange projects, 0x has gained by far the most traction in the short time since launching. Co-founders Will and Amir joined us to discuss the 0x protocol, the emerging 0x economy and the vibrant community they’ve built. Topics covered in this episode: How Will and Amir started 0x The definition of a decentralized exchange and why decentralized custody is key The 0x architecture Why 0x built a protocol and not just a decentralized exchange The role and business model of relayers The 0x token and its economy The 0x governance process Episode links: 0x: The Protocol for Trading Tokens 0x Whitepaper Front-running, Griefing and the Perils of Virtual Settlement (Pa

We’re joined by Greg Meredith and Nash Foster of the RChain Cooperative. A fundamentally new kind of blockchain platform, RChain is rooted in a formal model of concurrent and decentralized computation. Powered by the Rho Virtual Machine, and secured by Casper proof-of-stake, RCain is partitioned, or shareded by default, forming a network of coordinated and parallel blockchains. The project, which is formed as a coop, leverages correct-by-construction software development to produce a concurrent, compositional, and massively scalable blockchain. Topics covered in this episode: How Rchain spun out of the Synereo project The primary objectives RChain seeks to establish The fundamental principles of RChain and RLang The concepts of concurrency and parallelism in simple terms How building concurrent systems implies scalability The unique features of Casper consensus in the context of RChain The importance of namespaces in RChain Why this project was started as a cooperative The current status of the project and r

Zeppelin Co-Founder and CTO Manuel Araoz joined us to discuss his journey from building one of the first non-financial Bitcoin applications in 2012 to improving development and security practices for Ethereum smart contracts. We discussed the OpenZeppelin framework, a library of audited smart contracts as well as their new project zeppelin_os. Through on-chain, well-vetted and upgradeable smart contracts zeppelin_os aims to make developing Ethereum applications both easier and more secure. Topics covered in this episode: Manuel’s journey in the blockchain space from proof of existence to BitPay to Streamium to Zeppelin Why Manuel moved away from a pure Bitcoin focus to working on Ethereum Why Zeppelin focuses on smart contract security How smart contract security evolved since the start of Ethereum The OpenZeppelin framework of audited Ethereum contracts Why zeppelin_os and standardized, upgradeable on-chain contracts are the next evolutionary step The core component of zeppelin_os: Kernel, SDK and markeplac

Hashgraph is a new consensus algorithm that radically differs from proof-of-work as well as proof-of-stake consensus algorithms. While work on Hashgraph begun in 2012, it’s design is radically different from today’s blockchain architectures. The Hashgraph team claims that it has found an optimal consensus algorithm design that will be impossible to significantly improve upon. We were joined by Mance Harmon, who is CEO of the Swirlds, the company developing Hashgraph. Our conversation covered the origin story of hashgraph, how it compares to existing consensus algorithms and how Hashgraph works. Topics covered in this episode: Leemon Baird and Mance Harmon’s long history of building companies together What motivated Leemon Baird to start working on Hashgraph in 2012 The existing categories of consensus algorithms and their problems How Hashgraph consensus combines voting and gossip protocols The performance characteristics of Hashgraph How a public Hashgraph network could look like Episode links: Hashgraph

Over the past year, cryptoassets have exploded in popularity. From a mere $18bn at the start of 2017, the aggregate market cap of all cryptoassets recently reached $820bn as interest in Bitcoin and its cousins went mainstream. Jack Tatar and Chris Burniske joined us to discuss their new book ‘Cryptoassets: The Innovative Investor’s Guide to Bitcoin and Beyond’. It is one of the first systematic views on cryptoassets from a mainstream investor’s perspective. Topics covered in this episode: How Jack and Chris originally became interested in Bitcoin and cryptoassets Why the term cryptoassets is a good umbrella term for the different kinds of tokens The different categories of cryptoassets: Cryptocurrencies, cryptocommodities and cryptotokens How cryptoassets fit into an overall investment portfolio How to value cryptoassets Whether we are in a cryptoasset bubble and expectations for the future Episode links: Cryptoassets on Amazon Cryptoassets - Book Website Cryptoasset Valuations – Chris Burniske – Medium Wh

A significant part of the modern digital economy, is underpinned by machine learning models that are trained to perform tasks such as facial recognition, content curation, health diagnostics etc. Data to train machine learning models is the essential commodity of this century – a sentiment captured by epithets such as “”Data is the new oil””. Today’s dominant AI paradigm has companies focus their efforts on gathering data from their users in order to train models and monetise usage of the model. This model has many consequences such as loss of privacy for the user, consolidation of data in a handful of large companies, low access to data for startups and a fundamental impossibility of collecting sensitive data such as markers for depression. Our guest, Andrew Trask, is building OpenMined – a platform that merges cryptographic techniques such as homomorphic encryption and multi-party computation and blockchain technology to create the ability to train ML models with private user data. OpenMined will allow AI c

Blockchain technologies are changing the way we think about data archival and storage. For instance, most database systems can only capture the current state of a data set. This means we must rely on secondary backup systems to ensure historical data can remain accessible, a stark contrast from what the most basic of blockchains provide out of the box. Database systems that offer immutability and historical context for data would be greatly beneficial for companies as it would make internal and external audits much less costly and time-intensive. We’re delighted to bring you an interview with Flip Filipowski and Brian Platz. Flip is a veteran entrepreneur whose career spans 50 years, having worked for and founded some of the world’s largest software companies of the 80’s and 90’s. He is also the CEO of SilkRoad Equity and a Founding Partner of Tally Capital. Brian’s background includes having founded A List Appart in 1994, which is among the oldest and most influential web development blogs, and SilkRoad Tech

The prospect of providing digital cross-border payments for the world’s unbanked and underbanked population has always been one of the key use cases for Bitcoin. Cryptocurrencies can be seen as a way for people in developing countries to participate in the global financial market by allowing easy cross-border payments, cheap remittance transactions, and simplified lending options. We’re pleased to be joined by Elizabeth Rossiello, CEO and Founder of BitPesa. BitPesa provides companies in frontier markets with the financial infrastructure to facilitate commerce and payments, where traditional financial markets are known to be fractured and expensive. As an early Bitcoin company founded in 2013, BitPesa is now present in a handful of African countries and provides essential financial services to businesses, allowing them to send and collect payments, and perform quick and affordable Forex trades. Topics covered in this episode: Elizabeth’s journey to Bitcoin and BitPesa BitPesa’s vision and how it compares exi

Tim’s unbiased, honest, and sometimes controversial opinions provide a refreshingly realistic view of blockchain adoption and applications of this technology by people and businesses. Cutting through the hype, the over-sold press releases ad the blind optimism of a completely decentralized economy, Tim’s insights provide a sobering look at the state of the blockchain. Topics covered in this episode: Tim’s background and recent departure from R3 The current state of the enterprise blockchain market The state of Bitcoin in the context of the recent price increase Tim’s thoughts on the recent spike in ICO’s The rumors and concerns surrounding Bitfinex and Tether The rise of Bitcoin and cryptocurrencies as an asset class Current problems in Bitcoin: governance and centralization of power Tim’s new project: Post Oak Labs Episode links: Tim's Blog: Great Wall of Numbers Bitcoin Is Now Just A Ticker Symbol and Stopped B

We were joined by Founder Adam Perlow and Developer Asher Manning of Zen, a public blockchain project focused on building a decentralized financial system. The core premise of Zen is that none of the public blockchain networks are focused on financial asset. Zen is aiming to fill that gap through a Bitcoin-like UTXO architecture that supports multiple asset and smart contracts to enforce complex ownership rules. We talked through their original design choices, their use of formal verification, connection to Bitcoin and vision for a fully decentralized financial system. Topics covered in this episode: Why existing public blockchains are ill-suited for financial instruments Why Zen chose to use a Bitcoin-like UTXO architecture How Zen uses formal verification to allow smart contracts without a virtual machine or needing gas How the Active Contract Set reduces the burden on the miners Walking through creating, trading and settling a call option on Zen How Zen allows payments to be settled in Bitcoin Getting dat
