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 Episode links: Qubit Protocol Quantum attacks on Bitcoin, and how to protect against them Quantum Computers Pose Imminent Threat to Bitcoin Security - MIT Technology Review" Shor's algorithm - Wikipedia Elliptic-curve cryptography - Wikipedia This episode was hosted by Sébastien Couture, and is availble on YouTube, SoundCloud, and our website.

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 Episode links: Republic Protocol GitHub - republicprotocol/whitepaper: Republic Protocol whitepaper Dark pool - Wikipedia Shamir's Secret Sharing - Wikipedia De/Centralize - YouTube This episode was hosted by Sébastien Couture, and is availble on YouTube, SoundCloud, and our website.

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 Episode links: FOAM Website FOAM Blog This episode was hosted by Meher Roy & Sébastien Couture, and is availble on YouTube, SoundCloud, and our website.

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 Episode links: Hashed Health Website Hashed Health Blog Hashed Health Podcast This episode was hosted by Sébastien Couture, and is availble on YouTube, SoundCloud, and our website.

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 Comparing US to European regulation and why the US could end up more friendly Episode links: Coin Center Website The Bank Secrecy Act, Cryptocurrencies, and New Tokens: What is Known and What Remains Ambiguous FinCEN raises major licensing problem for ICOs in new letter to Congress.

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 Episode links: Sweetbridge Sweetbridge Whitepapers SweetTalk with Vinay Gupta & Scott Nelson This episode was hosted by Meher Roy & Sébastien Couture, and is availble on YouTube, SoundCloud, and our website.

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 the Segwit2X episode The lessons learned from founding Bloq What is Metronome and what problem does it aim to solve Metronome’s self-governance and how the system is meant to evolve The different smart contracts which make up Metronome How Metronome allows MTN tokens to move to different blockchains The economics of the protocol and the descending price auction system The upcoming Metronome token sale and development roadmap Episode links: Metronome: The Built-to-Last Cryptocurrency Metronome Owner's Manual Metronome FAQ Metronome Git Repo DSS - Dunvegan Space Systems, Inc The Long Now Foundation Bloq This episode was hosted by Brian Fabian Crain & Sébastien Couture, and is availble on YouTube, SoundCloud, and our website.

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 The Smart Contract Network Fallacy The Opportunity for Interoperable Chains of Chains Multicoin Capital Podcast This episode was hosted by Brian Fabian Crain & Meher Roy, and is availble on YouTube, SoundCloud, and our website.

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 (Part 1) Front-running, Griefing and the Perils of Virtual Settlement (Part 2) This episode was hosted by Brian Fabian Crain & Meher Roy, and is availble on YouTube, SoundCloud, and our website.
