177 - Jason Teutsch & Christian Reitwiessner: TrueBit, Scalable Off-Chain Computations for Ethereum
April 4th, 2017 by
epicenterbitcoin We're joined by Jason Teutsch and Christian Reitwiessner, the co-authors of a visionary whitepaper which describes Truebit. This protocol would allow complex computations to be executed on off-chain systems while being validated by Ethereum miners. The results of these computations would consequently be available to on-chain smart contracts. Read More -

175 - Miguel Vias: XRP's Future for Cross-Border Payments
March 21st, 2017 by epicenterbitcoin For a long time the native asset of the Ripple network XRP was the cryptocurrency with the second biggest market cap. But with much of the supply controlled by Ripple, it remained surrounded by controversy. Still, XRP remains an interesting asset to enable cross-border payments in the future. Miguel Vias recently joined Ripple after a long career on Wall Street to develop XRP as a liquid and widely accepted asset. Read More -
174 - Carsten Stöcker: How Blockchains Will Power the Energy Grids of Tomorrow
March 14th, 2017 by epicenterbitcoin Carsten Stöcker, Senior Manager Machine Economy & Blockchain at Innogy, shares his vision for how blockchains will serve as the transactional fabric for tomorrow's smart grids. In this new paradigm, energy is locally produced and blockchains provide the rails on which radically different local energy markets can be built. The German utility has been conducting blockchain experiments for several years and is soon releasing the Mobility Transaction Platform moveX. The Ethereum-powered platform will serve an ecosystem of electric vehicles with transaction layer needed for charging, car sharing and mobility as a service. Read More -

170 - Jae Kwon: Cosmos - The Internet of Blockchains
February 14th, 2017 by epicenterbitcoin We're joined by Jae Kwon, CEO and Founder of Tendermint, the team which will soon launch the Cosmos Network. Cosmos aims to build the internet of blockchains: A global network of blockchains, connected through hubs that allow trustless token transfer. Jae joined us to discuss the Cosmos vision, the underlying Tendermint consensus algorithm and upcoming fundraiser. Read More -
169 - Prof. Silvio Micali: A New Scalable and Secure Approach to Byzantine Fault Tolerant Consensus
February 7th, 2017 by epicenterbitcoin We're pleased to be joined by Professor Silvio Micali, a computer scientist at MIT, who is known for his work in many of the technologies blockchains rely on today. Prof. Micali describes the concept of Algorand, an alternative approach to proof of work which offers high security guarantees while allowing the network to scale with demand. Relying only on a trivial amount of computation to validate transactions, Algorand also reduces the probability of network forks to near-zero. It uses novel mechanisms to select validators for blocks and enabling them to come to consensus on them. Read More -
168 - Rick Dudley: The Future of Ethreum as a Strongly Typed Proof-of-Stake Blockchain Network
January 31st, 2017 by epicenterbitcoin We're joined by Rick Dudley, an opinionated and passionate blockchain developer who is actively involved in multiple projects. He works as a DevOps at Monax, works closely with Vlad Zamfir on implementing Casper in Ethereum, is a leading member of the Coala organization and is Founder and CEO of the startup Vulcanize. Rick gives us insider insights on Ethereum and on how the project may evolve, in particular, once Casper is implemented and when more robust, strongly typed language VMs are made available to the protocol.

167 - Peter Harris: Democratizing the Music Industry with the Streaming Music Cooperative Resonate
January 24th, 2017 by epicenterbitcoin After the successful Ethereum crowdfunding campaign, musician and web developer Peter Harris saw a path to creating a fair, decentralized music streaming platform. Out of that Resonate was born. Peter joined us to discuss why the dysfunctional structure of the music industry results in a bad deal for musicians and why a decentralized platform supported by blockchain technology and run as a cooperative represents a better way forward.

166 - G. Andrew Stone & Andrew Clifford: Bitcoin Unlimited
January 16th, 2017 by epicenterbitcoin Years into the controversy around how to scale Bitcoin, there have been many challengers to Bitcoin core's dominance. After XT, Classic and others have faded, Bitcoin Unlimited has been gaining traction and emerged as plausible new way forward. Bitcoin Unlimited wants to make the block size a parameter that is set by miners and nodes, but not fixed at a network level. They argue a natural fee market would emerge, allowing Bitcoin to rapidly scale and realizing its promise of electronic cash as well as store of value. The project is also member-driven, with democratic decisions driving its development decisions. Core developer G. Andrew Stone and Bitcoin Unlimited President Andrew Clifford joined us for the episode. Read More -

164 - Ari Juels: Using Hardware Enclaves to Provide Trusted Data to Smart Contracts
January 2nd, 2017 by epicenterbitcoin Ari Juels, a Professor at Cornell Tech 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, one who uses a Town Crier feed would not need to trust its operator as code execution would be guaranteed signed by the hardware. Read More -
