Joey Krug: Augur – A Decentralized Crowdsourced Prediction Market Built on Ethereum

Prediction markets are fascinating financial instruments which have proven to be accurate at making predictions on things like the outcome of elections, geopolitical events and sporting events. But in our heavily regulated financial world, they are the subject of much controversy. In 2013 for instance, a well-known US prediction market, Intrade, was forced to shut down following a civil suit filed by the CFTC. While some people consider prediction markets to be a useful tool for society, others consider them to be a form of gambling, which is one of the reasons why they have been met with such resistance in certain countries. A purely decentralized prediction market would operate outside the scope of the regulated financial world and be resistant to censorship and outside intervention. We’re joined by Joey Krug, Co-Founder and Core Developer at Augur, a decentralized prediction market built on Ethreum. The project, which was initially meant to be a Bitcoin sidechain, has ported to Ethereum and is currently in beta on the Testnet. Users can forecast real-world events, such as the outcome of the US election, and earn profits if they are accurate in their predictions. Reporting on events is crowdsourced using a consensus-based system similar to proof-of-stake. Topics covered in this episode: How prediction markets work The controversy around prediction markets The Augur project and what it is trying to achieve The evolution of Augur The different components of Augur Reporting on events and the reputation token Security, attack vectors and how they can be mitigated Augur’s business model The ethical aspects of prediction markets Augur’s structure and governance Episode links: Augur Augur Git Repo Augur Docs EB139 – Martin Köppelmann: Gnosis – The Ethereum Prediction Market EB97 – Paul Sztorc: Truthcoin & Prediction Markets, From Information-Overload To Crowd Intelligence EB98 – Robin Hanson: Futarchy, Prediction Markets And The Challenge Of Disruptive Technology EB141 – Ralph Merkle: Revolutionizing Democracy Using DAOs This episode is hosted by Brian Fabian Crain and Sébastien Couture.

Claire Warren & Scott Farrell: DnA Contracts – Bringing Human Discretion to Smart Contracts

Blockchain smart contracts are self-executing contracts composed of computer code. These programs, which are executed by the entirety of the network, enforce the rules described within the code. Effectively, in this realm, code is law. And as we’ve seen recently, altering the outcome of that code after it has been deloyed, should we later realize that it was flawed or did not produce an intended result, can be messy. In addition, there are instances where human intervention can be necessary or even desirable. Take a mortgage agreement for example. Should a smart contract be entrusted with the responsibility of making a decision when the borrower can no longer make his payments? In cases such as this, subjective human intervention is be necessary. Scot Farrell and Claire Warren, lawyers at the global law firm King & Wood Mallesons, think that humans should not be automated out of every process. While code is logical and predictable, it cannot act reasonably or take into account certain unforeseen events. They have proposed DnA contracts (Digital and Analog), where automation can occur when absolute automation is possible, but where humans may intervene at the edges and provide input when needed. Topics covered in this episode: What issues DnA contracts are trying to address The basic concepts behind DnA contrats The scenarios where DnA contracts may be valuable Examples of DnA contracts applied to interest rate swaps and mortgages How DnA contracts could be integrated with blockchain technologies The impact of DnA contracts on legal services Episode links: How to use humans to make “smart contracts” truly smart DnA Contracts proposal on GitHub This episode is hosted by Meher Roy and Sébastien Couture.

Ralph Merkle: Revolutionizing Democracy Using DAOs

Legendary scientist and cryptography pioneer Ralph Merkle joined us to discuss his recent paper on DAOs. Merkle examined how the voting mechanisms in today’s democracies are flawed and how a decentralized, transparent DAO making decisions using prediction markets could create more efficient democratic systems. Topics covered in this episode: Merkle proofs, Merkle Roots and his early forays into cryptography Blockchains as living organisms Why DAOs will be subject to a Darwinian evolutionary process Why voting is flawed and we need new governance methods to save democracy The concept of a DAO democracy How prediction markets and futarchy would help govern a DAO democracy Episode links: Ralph Merkle DAO Democracy Paper [PDF] Ralph Merkle's Homepage Ralph Merkle's Wikipedia page EB98 - Robin Hanson: Futarchy, Prediction Markets Tim Urban: Why Cryonics Makes Sense Alcor - Life Extension Foundation This episode is hosted by Brian Fabian Crain and Meher Roy.

Manfred Karrer: Bitsquare – The Decentralized Open-Soure Cryptocurrency-Fiat Exchange

Exchanges are often criticized as a central point of failure of the cryptocurrency space. This isn’t without justification as, in recent years, we have seen a number of exchanges get hacked, robbed, or embezzled by their founders, which is far from insignificant. One proposed alternative are decentralized exchanges that would allow people make peer-to-peer trades using sophisticated smart contracts. However, there remains the fundamental challenge of interfacing with the legacy banking system. Manfred Karrer joins us for a lengthy discussion on Bitsquare, a decentralized cryptocyrrency exchange which supports most fiat currencies and cryptocurrencies. Built to be a decentralized equivalent of LocalBitcoins, the Bitsquare client, which connects to the peer-to-peer network, uses Tor by default, which makes it almost completely anonymous. There are also a number of safeguards in place to eliminate the potential for fraud and theft, as well as an arbitration system to resolve disputes between traders. Topics covered in this episode: The motivation behind Bitsquare The Bitsquare client and user experience A walkthrough of a typical trade The mechanics of the order book The fiat currency transfer mechanism The current and future arbitration process Manfred’s thoughts on DAOs Bitsquare’s product roadmap Episode links: Bitsquare Website Bitsquare Whitepaper Risk Analysis Arbitration System Github Repo This episode is hosted by Meher Roy and Sébastien Couture.

Martin Köppelmann: Gnosis – The Ethereum Prediction Market

Few things arouse among free market believers and enthusiasts of decentralization as prediction markets do. By allowing people to bet on any range of outcomes they promise more efficient markets and better information. Few people have worked with as much dedication on making the promise of prediction markets a reality as Martin Köppelmann. After founding the Bitcoin prediction market Fairlay, he turned to Ethereum and started the Ethereum-based prediction market Gnosis. We discussed his views on the DAO heist, differences between Fairlay and Gnosis and their upcoming tokensale. Topics covered in this episode: How the DAO heist happened and what we should learn from it The Bitcoin prediction market Fairlay From Fairlay to Gnosis: Building a prediction market on Ethereum The Gnosis architecture Gnosis’ planned crowdsale and DAO Gnosis business model and what will determine the value of the tokens The difference between Gnosis and Augur Episode links: Gnosis Website Gnosis Forum Fairlay 7 Reasons to Make a Prediction The Big TheDAO Heist FAQ - Part 1 The Big TheDAO Heist FAQ - Part 2 EB98 - Robin Hanson: Futarchy and Prediction Markets episode This episode is hosted by Brian Fabian Crain and Meher Roy.

Arthur Breitman: Tezos – A Self-Amending Crypto-Ledger

The lack of an explicit governance mechanism has created deep problems for Bitcoin. Ethereum, with the DAO-related soft/hard-fork discussions, may face similar challenges ahead. Yet, already in 2014 Arthur Breitman quietly started working on cryptocurrency network Tezos that has an explicit mechanism to let coinholders vote on protocol upgrades. Our discussion with Breitman centered around how explicit governance could lead to a more secure and evolutionary protocol. We also discussed Tezos’ approach to smart contract that tries to prevent bug-riddled and insecure smart contracts such as the DAO which has thrown Ethereum into a deep crisis. Topics covered in this episode: Why stakeholders voting on forks can prevent consensus attacks The mechanics of Tezos’ governance How an upgrade mechanism could allow Tezos to rapidly and radically evolve Why the programming language in which smart contracts are written is crucial for security Why a functional language that allows formal proofs such as OCaml is more suited for smart contracts than Ethereum’s solidity The road ahead for Tezos Episode links: Tezos website Tezos position paper [PDF] Tezos whitepaper [PDF] This episode is hosted by Brian Fabian Crain and Meher Roy.

Stephen Palley: Lawmodynamics – How to Sue a DAO

For many the promise of decentralized applications and DAOs is to be beyond the limitations and rigidity of the existing legal system. There is no question that where DAOs can roam freely, innovation can accelerate. But can the law, courts and regulations be left behind so easily? Lawyer Stephen Palley joined us to discuss what happens when the new and old worlds collide and how courts will look at what goes on in the land of DAOs and DApps. Topics covered in this episode: Whether trust is reduced, removed or just shifted elsewhere in blockchain systems If creating decentralized applications could create liability risks Why courts will impose a legal structure if a formal one doesn’t exist The concept of jurisdiction and how it could affect DAOs Why one should be careful with saying a DAO provides insurance Episode links: How to Sue A DAO Blockchain Jurisdiction Smart Contracts and Smart Lawsuits Blockchain and the First Law of Lawmodynamics Smart Contracts, Performance and Trust DAO Insurance Company, Inc All of Stephen Palley's LinkedIn Posts EB125 Florian Glatz: Defining a Legal Framework for DAOs EB132 Stephan Tual: A Universal Sharing Network and a $150m DAO This episode is hosted by Brian Fabian Crain and Meher Roy.
