Daniel co-founded that organization last year with Michael Goldstein and Pierre Rochard to educate the Bitcoin community on the foundational ideas that led to the creation of Bitcoin. The Satoshi Nakomoto Institute is dedicated to shedding light on the ideological history of Bitcoin and keeping its controversial roots from being marginalized. Topics discussed included: - What it means to be a libertarian, crypto-anarchist. - The perception of Bitcoin and the future of the bitcoin ecosystem - The viability of alternative currencies Links mentioned in this episode: - The Satoshi Nakamoto Institute: http://nakamotoinstitute.org - Bitcoinist.net: http://bitcoinist.net/author/daniel-krawisz/ - Youtube channel: https://www.youtube.com/channel/UCZTnjU-KAiuZl7g-dNHUyUg Sponsors: - Gems: http://getgems.org/ - Shapeshift: https://shapeshift.io/ - Fairlay: http://fairlay.com/ Show notes: http://epicenterbitcoin.com/podcast/056 SoundCloud: http://soundcloud.com/epicenterbitcoin/eb-056 Epicenter Bitcoin is hosted by Brian Fabian Crain & Sébastien Couture. - Visit our website: http://epicenterbitcoin.com - Subscribe to our newsletter: http://epicenterbitcoin.com/newsletter - Twitter: http://twitter.com/epicenterbtc

It's the original decentralized autonomous organization idea that has informed many projects that have been on the podcast (Swarm, Ethereum, Factom, Storj, etc). For Matan, the vision originally led to found decentralized ride-sharing application LaZooz. One year ago, he left LaZooz to found Backfeed, which is building the tools that so far have been missing to make mass collaboration without a central party possible. Topics covered included: - How he became interested in blockchains and started the ridesharing application LaZooz - Backfeed's vision for a social operating system for decentralized organizations - The role of reputation, proof-of-value and tokens in Backfeed - The applications Backfeed is currently building - The business of model of Backfeed Links mentioned in this episode: - Backfeed website http://bit.ly/1TkgZJw - Backfeed: An Introduction for Mere Mortals http://bit.ly/1nuzS0B - Matan Field DevCon Talk about Backfeed http://bit.ly/1UmNogV Sponsors: - Ledger Nano: Smart card security for your Bitcoins - Get 10% off your first order when you use the code EPICENTER at http://ledgerwallet.com - Hide.me: Protect your privacy and personal data with a free VPN account at Hide.me/epicenter Show notes: http://epicenterbitcoin.com/podcast/115 YouTube: https://youtu.be/SsCxgez1XBo SoundCloud: http://soundcloud.com/epicenterbitcoin/eb-115 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

The deterministic nature of Etehreum-style blockchains makes it impossible for them to incorporate functions allowing them to do things such as make API calls to websites and data feeds. Though oracles are often cited as the solution to this problem, they require users to place a high level of trust in their operators, a model which would undermine the very nature of a decentralized smart contract. Ari Juels, a Professor at Cornell Tech (Jacobs Institute) and former Chief Scientist of RSA, joins us to discuss his work on Authenticated Data Feeds for Smart Contracts. These 'Town Crier' feeds would act as bridges between smart contracts and websites, srapping data over TLS and feeding to to a smart contract. Relying on sophisticated hardware enclave technology (Intel SGX), one who uses a Town Crier feed would not need to trust its operator as code execution would be guaranteed signed by the hardware. Topics discussed in this episode: - Ari's background in cryptography and cryptocurrencies - The pain points with oracles as we describe them today - The idea behind Authenticated Data Feeds - The hardware and software architecture of the Authenticated Data Feed model and how hardware isolation works - How Authenticated Data Feeds could be used to create criminal smart contracts - The differents ways in which criminals could use Authenticated Data Feeds to release bounties for crimes such as private key theft or even murder - Countermeasures which may prove effective in fighting criminal smart contracts - The Initiative For Cryptocurrencies & Contracts (IC3) and its raison d'être Links mentioned in this episode: - Ari Juels' website: http://www.arijuels.com - Town Crier: An Authenticated Data Feed for Smart Contracts (white paper): http://www.initc3.org/files/tc.pdf - The Ring of Gyges: Investigating the Future of Criminal Smart Contracts (white paper): http://www.initc3.org/files/Gyges.pdf - IC3 - The Initiative For Cryptocurrencies & Contracts: http://www.initc3.org/ Sponsors: - Jaxx: Wallets that Unify the Blockchain Experience Across Devices - http://jaxx.io Watch or listen, Epicenter is available wherever you get your podcasts.

The web of documents as abstractly conceived by Tim Berners Lee needed a browser for users to explore the content of these documents. Similarly, the Ethereum dev team is working on a ‘DApp browser’ to explore the web of smart contracts running on the Ethereum blockchain. Here, I interview Alex van der Sande and Fabian Vogelsteller who are lead developers of Mist, the Ethereum Dapp browser. At the Devcon, they demoed an early version of the browser with wallet functionality, ability to upload and see contracts on Ethereum. They used this early version to create a company running purely on the blockchain. This was a very impressive demo, and the videos for the demo shall be uploaded by the Ethereum Dev team. Our interview covers themes such as: The vision behind mist, and why Ethereum needs a Dapp browser. The difference between this early release and the full blown browser. Challenges in building the browser. Next steps. Check this video in order to gain an appreciation of how users will interact with smart contracts in the future.
