The ambitious goal of the project is to form an decentralized organizations that efficiently makes investment decisions and generates a return for the token holders. Computer Science professor Emin Gün Sirer and researcher Vlad Zamfir joined us to discuss the various security issues with the daring project and why they've called for a temporary moratorium on funding proposals. Topics covered included: - How the DAO works - What the role of the curators is - What splits are and how they became a way to withdraw funds - Why the DAO has a bias towards approving proposals - How attackers could 'stalk' token holders when withdrawing their funds - How the DAO can be upgraded Links mentioned in this episode: - A Call for a Temporary Moratorium on The DAO Blog Post http://bit.ly/28ftfC1 - A Call for a Temporary Moratorium on The DAO Full Paper PDF http://bit.ly/1TRJgo9 - EB132 – Stephan Tual: Building A Universal Sharing Network On Ethereum And A $150M DAO http://bit.ly/25IMFk4 - Understanding the DAO Accounting http://bit.ly/22JmkNn - The DAO website http://bit.ly/1PAkhcq - Meher's 'split DAO' reward token attack http://bit.ly/1U42Wau Sponsors: - GTEC: Blockchain Innovation Award epicenterbitcoin.com/gtec - Hide.me: Protect your privacy and personal data with a free VPN account at Hide.me/epicenter Show notes: http://epicenterbitcoin.com/podcast/134 SoundCloud: http://soundcloud.com/epicenterbitcoin/eb-134 Epicenter Bitcoin is hosted by Brian Fabian Crain, Sébastien Couture & Meher Roy. - Visit our website: http://epicenterbitcoin.com - Subscribe to our newsletter: http://epicenterbitcoin.com/newsletter - Twitter: http://twitter.com/epicenterbtc

For example, the Blockstream sidechains project foresaw hundreds of blockchains coordinating together to form an ‘Internet of Chains’ delivering extensibility to the Bitcoin system. Recently, Dr. Gavin Wood, co-founder of Ethereum and Parity, put forth Polkadot, a technical vision to achieve the similar end-goals using different system architecture. Polkadot could enable individual blockchain networks to share security and communications infrastructure with other blockchain networks, forming in effect an ‘Internet of Blockchain networks’. Melonport, a team based out of Zurich, has taken up the challenge of deploying the Polkadot network and also building decentralized asset management software on the same network. In this episode we converse with Mona El Isa and Reto Trinkler, co-founders of Melonport, in order to discover more about the overall vision.

What is still more nebulous, but could turn out just as disruptive is how smart contracts while transform the legal system and our understanding of what contracts are and how they work. Legal researcher Lukas Abegg who is currently finishing his PhD on patent law issues around 3d printing and has been researching smart contracts as well joined us to discuss the question whether code is law and what blockchain can learn form 3d printing. Topics covered included: - The patent law questions around 3d printing - How legal issues around 3d printing are like issues around smart contracts - How information theory can help us conceptualize smart contracts - The thesis of Lessig's book 'Code is Law' - The case for law regulating code - Why Alternative Dispute Resolution has big potential for blockchain applications Links mentioned in this episode: - Code is Law?
