*CoinSummit London Conference Series - July 10 and 11, 2014* In this episode we talk to Olivier Janssens, a Bitcoin early adopter and investor, and his associate Andrew Turner. We discussed Olivier’s recent $100,000 bounty replace the Bitcoin Foundation. He told us why he chose Mike Hearn’s Lighthouse project as the winner of 40% of that bounty and the effect that Lighthouse could have on Bitcoin core development funding. We also interviewed Michael Jackson. He’s the former COO of Skype and currently a VC at Mangrove Partners. We discussed the recent EBA opinion paper. We also talked about his experiences with the regulation of new and disruptive technologies from his days at Skype as well as investing in Bitcoin companies.

However, mobile phones from the early 2000's could arguably run more complex operations than these networks combined. While blockchains themselves may never reach the level of computational power of modern computers, they may be leveraged as the underlying verification layer for centralized computing. We're joined by Jason Teutsch and Christian Reitwiessner. They are 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. Truebit makes clever use of proof systems and game theory to build a protocol where a Task Giver can ask a third party, the Solver, to execute a complex computation in exchange for a reward. Not limited to Solidity, these could be executed in traditional languages such as Go, Python or C++. Verifiers could then challenge the results, incentivising the Solver to be honest or see his reward be stripped away. This incentive structure would guarantee fast and reliable results while eliminating the need for a trusted third party. Topics discussed in this episode: - Jason and Christian respective backgrounds in the ecosystem. - The core problem being addressed by Truebit - Why a scalable decentralized computational resource is desirable - How Truebit makes use of proof systems and game theory to enable trusted computations off-chain - How the verification game works the incentive structures proposed in Truebit - The various use cases for Truebit - How Truebit could allow for blockchain interoperability without the need for ""blockchain of blockchains"" type networks Links mentioned in this episode: - TrueBit Website: http://truebit.io - TrueBit Subreddit: https://www.reddit.com/r/truebit/ - TrueBit: Scalable Computation talk by Christian Reitwiessner at Ethereum Meetup in Berlin: https://www.youtube.com/watch?v=sO2tEOBBFOE - Slides for the Scalable Computation talk: https://chriseth.github.io/notes/talks/truebit_meetup_2017-03 Sponsors: - Jaxx: Wallets that Unify the Blockchain Experience Across Devices - http://jaxx.io This episode is also available on : - Epicenter.tv: https://epicenter.tv/177 - YouTube: http://youtu.be/QY0OUTaIWIc - Souncloud: http://soundcloud.com/epicenterbitcoin/eb-177 Watch or listen, Epicenter is available wherever you get your podcasts.
