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

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

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

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

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

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
