Interview with Stefan George and Martin Koeppelmann of GroupGnosis at DEVCON1 in London
In this video, I talk to the talented duo of Stefan George and Martin Koeppelmann, who have implemented a prediction market on the Ethereum blockchain called Gnosis. Previously, they ran a bitcoin prediction market called Fairlay.
Gnosis is already live and people used the market to estimate how much money Augur would raise in their token sale. We focus on the following themes:
What is the difference between their project and the Augur effort?
Advantages of decentralised prediction markets.
Swappable oracle systems and advantages offered by separating oracle logic from market logic.
Their areas of focus - back-end, market design etc.
The idea of the ultimate oracle.
Check out the video in order to gain an appreciation for alternatives to Augur.

David A. Johnston is a very active member of the Bitcoin community. Aside from speaking at about every Bitcoin conference there is, David is the Managing Director of the DApps Fund, a board member MSC Protocol Foundation, as well as Co-founder and Executive Director of the BitAngels Network.
On this episode we go deep in to decentralized applications, and who better to talk to about DApps than the creator of ""Johnston's Law"" which states ""Everything that can be decentralized, will be decentralized"". We talked to David about the recent whitepaper he co-wrote titled ""The General Theory of Decentralized Applications, DApps"" which defines the different types of DApps and a number of best practices with regards to funding, token distribution, business models etc. We also discussed the DApps Fund, BitAngels Network and the Master Protocol, and his involvement with those projects.

In the last 20 years, content publishing platforms have proliferated to an almost insane number. There are countless places where people and companies can post articles, blogs, videos, photos, live content and so on. Despite this diverse offering, little innovation has happened in monetizing content, which still mostly remains ad-based.
We're joined by Ryan X. Charles, Bitcoin Developer and Founder of Yours. Yours would like to address the monetization problem by allowing content producers to earn Bitcoin when they create good content. Yours is an in-browser application which implements a Bitcoin wallet and enables micro-transactions through their own implementation of the Lightning Network. Content Creators are paid by Curators who attribute value to the content. Curators are themselves rewarded when content they find valuable goes viral.
Topics discussed in this episode:
- Ryan's background as the Lead Developer of BitCore, and his experience at BitGo and Reddit
- What is Yours and what types of applications it enables
- The technical components of Yours
- The Yours application and how users post and access content
- Why he chose to build Yours on bitcoin
- How micropayments are implemented in Yours
- How Yours addresses the issue of copyright infringement
- What challenges Yours may face in order to reach critical mass

We've made it to episode 100! Our guest for our celebratory episode is Juan Benet, inventor of the Inter-Planetary File System and founder of Protocol Labs. IPFS is a distributed file system that seeks to connect all computing devices with the same system of files. The possibilities for IPFS could range from distributed cloud hosting to websites without central servers to even replacing HTTP. It's a project as audacious as any we've had on the podcast and Juan did an outstanding job explaining the technology and vision.
Topics covered included:
- Why HTTP is broken and how IPFS could complement and ultimately replace it
- The different technologies IPFS is based on including DHT, Git, Bittorrent and SFS
- How IPFS could enable the 'permanent web' by distributing file storage
- Content-addressing and how hosting works on IPFS
- Mutable content and the Interplanetary Naming System (IPNS)
- Filecoin and incentivizing hosting on IPFS
- Why IPFS is a great fit for smart contracts

In the short history of the Bitcoin industry, there has been an impressive amount of high profile hacks, ranging from a few hundred thousand to many millions of dollars. In all of these, customers, Bitcoin users, where robbed of their funds because poor security policies, negligence, incompetence, or plain old scamming. Recently, the cryptocurrency conversion service ShapeShift fell victim to a hack in which over $200,000 of company funds were stolen, initially by an employee, and then by a hacker to whom this employee had sold sensitive company information. Luckily, no customers lost any money as ShapeShift does not hold any funds on behalf of users.
We talked to ShapeShift CEO Erik Voorhees who walks us through this captivating ordeal, which sounds like it could be the plot of a movie. He speaks about how the company is trying to recover and what he has learned from this unfortunate event.
Topics we discussed on this episode:
- How the ShapeShift hack went down
- What steps the company has taken to avoid this from happening again
- What he learned from the hack
- ShapeShift's long-term vision as a company and product
- Ethereum's role in their recent growth
- His history as an entrepreneur in the Bitcoin space
- His views on libertarianism and the long-term impact of Bitcoin on that movement

Few crypto projects have gotten as much attention and caused as much controversy as Steem. The blockchain-based social media platform launched early this year and managed to gain real user traction building up a vibrant community of contributors. The Steem token quickly entered bubble territory reaching a market cap of almost $400m and losing 90% of its value since.
Steem Co-Founder and CEO Ned Scott joined us to discuss the ambition of the project and its short tumultous history. We also discussed some of the accusations against Steem and its unorthodox launch.
Topics discussed in this episode:
- How Steem was launched out of the BitShares community
- The different components and tokens of the Steem system
- How Steem rewards content contributors
- The controversial Steem launch and criticisms of the project
- Why Steem transitioned from Proof-of-Work to Proof-of-Stake
- The potential disbalance of power due to the Steem distribution

One of the major drawbacks of Bitcoin is its low transaction throughput. Maxing out only a handful of operations per second, there have been many proposals to scale it up so that it can compete with existing distributed database technologies. As the blockchain's demand continues to increase, it's unclear if the Bitcoin protocol will ever be able to handle thousands, if not millions of transactions per second. BigchainDB is taking a different approach. Rather than trying to scale up blockchain technology, it starts with a big data distributed database, RethinkDB, and adds blockchain features and characteristics.
Trent McConaghy, Co-founder and CTO of Ascribe and BigchainDB, joins us to talk about how this protocol may become to databases, what IPFS and Ethereum are to distributed filestorage and computing, respectively. Able to perform more than one million writes per second and capacities in the petabytes, BigchainDB has the ambition to become the world's public database platform.
Topics we covered include:
- A brief update on Ascribe since Trent was last on the show
- The motivations behind BigchainDB and that problems it's trying to solve
- How BigchainDB plans to solve the typical scalability bottlenecks found in blockchain protocols
- BigchainDB's capacity, performance and latency characteristics
- BigchainDB's consensus model, applied to RethinkDB
- Potential application for BigchainDB, in both centralised and decentralised application stacks

For decades, science and academia have leveraged distributed computing to solve massive computational problems. Distributed grid computing schemes allow donors to volunteer their desktop computer's idle resources toward scientific projects in physics, biology, and chemistry, where large amounts of parallel computing resources are necessary. Relying on software like BONIC, these networks provide features such as built-in fault tolerance and result verification. And with the proliferation of mobile and IoT, the potential for massively distributed grid networks has never been greater.
Gilles Fedak, a researcher at the French computer science research body Inria, joins us to discuss a new project which aims to build a high-performance distributed cloud infrastructure marketplace. Relying on mature grid computing technologies, iExec utilizes Ethreum to organize a peer-to-peer marketplace of computing resources, allowing anyone to rent their idle resources to grid networks. If it succeeds to execute on its vision, this game-changing project could revolutionize distributed computing through cost reduction and commoditization of resources.
Topics discussed in this episode:
- Gilles' background as a distributed computing researcher
- Distributed computing and it's applications in science and industry
- The problems we see in distributed computing networks
- The iExec project and its vision for a distributed computing resource marketplace
- How iExec works as an Ethereum smart contract
- The different components and participants of iExec
- The iExec token and upcoming crowds ale
- The project's business model and roadmap
