Ajay Prakash & Gavin Brennen: Qubit Protocol – Quantum Computing & The Coming Threat to Crypto
With the advent of mature quantum technologies, many of the critical cryptographic protocols which secure the Internet, financial transactions and even military secrets may become susceptible to new attack vectors. For instance, while it may take a computer millions of years to decipher a public key’s corresponding private key, a sufficiently powerful quantum computer might achieve this in a reasonable amount of time. With this reality looming over us, many in the blockchain space worry that someone with access to a quantum computer might one day have the ability to steal their hard-earned crypto.
We’re joined by Ajay Prakash and Gavin Brennen, founders of the Qubit Protocol, a decentralized blockchain-enabled governance protocol that is meant to select and fund the best startups in the quantum world. As a co-author of the recent paper “Quantum attacks on Bitcoin, and how to protect against them,” Gavin walks us through the primary threats that quantum computing poses on Bitcoin. Among the major vulnerabilities are hashing functions and Elliptic Curve algorithms used for digital signatures, both fundamental components of Bitcoin, as well as many other blockchain protocols.
Topics covered in this episode:
What are quantum technologies and how they differ from the existing paradigm
The areas and industries which are to benefit most from quantum computing
A refresher on hashing algorithms as one-way functions
What a quantum attack on Bitcoin mining might look like
How Elliptic Curve digital signature algorithms work and how public and private keys are generated
The three types of attacks a quantum computer could perform digital signatures
The expected timelines for these attacks to be viable
The potential countermeasures which could circumvent quantum attacks on Bitcoin
The Qubit Protocol as a DAO to fund quantum technology startups and the challenges of investing in the quantum space
The project’s roadmap and upcoming ICO

Loong Wang & Taiyang Zhang: Republic Protocol – A Decentralized & Trustless Crypto Dark Pool
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 intervention of a trusted third party.
Topics covered in this episode:
Taiyang and Loong’s respective backgrounds
Dark pools, their role in traditional financial markets, and their economic impact
Dark pools in crypto markets
The Republic Protocol and the problems it aims to address
The different components and participants of the Republic Protocol
The Shamir Secret Sharing Scheme and its role in protecting orders from being divulged to the public
The role of nodes in Republic Protocol’s DHT network
The purpose of the REN token as an incentive mechanism protecting against malicious actors
Republic Protocol’s use of atomic swaps for decentralized settlement
The project’s recent ICO and release roadmap

Ryan John King: FOAM – A Geospatial Proof of Location Protocol for Blockchains and Dapps
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 participants to arrive at consensus on whether an event or agent is verifiably at a particular point in time and space.
Topics covered in this episode:
Ryan’s background and how he became involved in the space
How geospatial tracking works and the pitfalls of GPS
The vision for FOAM and the problem it is trying to solve
The proposed Crypto-Spatial Coordinate Standard
FOAM’s Spacial Index fullstack visualizer
The Proof of Location Protocol proposed by FOAM
Low-power radio networks and their role in the system
The civil and business applications for FOAM

Corey Todaro & John Bass: Hashed Health – Rebooting The Healthcare Industry
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 episode:
John and Corey’s respective backgrounds in the building technology for the healthcare sector
Nashville as a hub for the US healthcare industry
What is Hashed Health and what problems the company is trying to solve
The particular issues facing the US and global healthcare sectors
How healthcare in the US differs from that of European countries
The different entities of Hashed Health: Hashed Collective, Hashed Labs, and Hashed Enterprise
Hashed Enterprise and the products they are building for the industry

Bob Summerwill: Sweetbridge – Rewriting the Operating System for the World Economy
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 up by enabling individuals and organizations to borrow from themselves interest-free.
Topics covered in this episode:
Bob’s background as a game developer
How Bob got involved with Ethereum and his role at The Ethereum Foundation
What is the Sweetbridge and how it aims to transform global business
How one can use Sweetbirdge to collateralize assets and borrow money
The different protocol layers of Sweetbridge
How Bridgecoin and Sweetcoin work, and their respective roles
The role and goals of the Sweetbridge Alliance
The upcoming token sale
The project roadmap and upcoming product releases

Jeff Garzik: Metronome – Of Bitcoin Satellites and Built-to-Last Chain-Hopping Tokens
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

Amir Bandeali & Will Warren: 0x Protocol and the Decentralized Exchange Frontier
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
