Our regulatory expert Siân Jones joined us to discuss her work on a regulatory framework for distributed ledger technology (DLT) for Gibraltar. We discuss how the framework differs from other efforts and aims to attract rather than curtail blockchain businesses. We also covered why the rapid changes require the flexibility of a principle-based approach to regulation. Finally, we discussed current trends around ICOs and how they could be impacted by regulation.

The saying goes: if you’re not paying for it, it’s likely that you’re the product. And with the rise of targeted ads, user behavior tracking, and alike, more and more users are turning to ad blocking software to protect their privacy and improve their browsing experience. In the last 25 years, the content monetization and Internet advertising industries have evolved to become complex ecosystems with multiple intermediating layers between users, publishers, and advertisers. This has created a situation where user’s rights are constantly violated and where little accountability exists.
We’re joined by Brendan Eich, Founder, and CEO of Brave. As an early Internet pioneer, Brendan created Javascript while working at Netscape in the mid 90’s, and helped found the Mozilla Foundation and Mozilla Corporation, where he served as CEO for several years. Brave is a new desktop and mobile browser which blocks ads and tracking by default. This has the advantage of drastically improves page load times while protecting users’ privacy. But Brave is much more than just a browser. Their team will launch the Basic Attention Token, which will serve as the currency of attention marketplaces between publishers, advertisers, and users. With the ambition to turn the Internet advertising industry on its head, this new attention economy marketplace will eliminate the need for unneeded intermediaries, provide publishers with new content monetization models and remunerate users when they chose to share their data with advertisers.

Data is the new oil, and those who control massive amounts of it have a major competitive advantage. That advantage becomes exponential when that data is used to teach artificial intelligence. Companies such as Google, Facebook and Amazon have a far greater probability of building strong AI than smaller actors simply by the sheer amount of user data and metadata they possess. Let’s now envision an alternate reality where big data lives on public infrastructure and is accessible to anyone who wishes to use it for the purpose of teaching AI. Big data as a public resource could have the potential to enable vast amounts of innovation at the edges, far greater than that of a small set of incumbents building large centralized AI systems.
We’re joined by Trent McConaghy, who is the CTO and Co-founder of BigchainDB and Ascribe. Trent brings along a special surprise guest, Fred Ehrsam, former Co-founder at Coinbase. For the first half of the show, we have a fascinating discussion with Trent and Fred about the intersection of AI and blockchain technologies, and the implications of publicly available data sets on innovation in AI. For the second half of the show, we talk with Trent about the public implementation of BigchainDB, the Interplanetary Database (IPDB), and the applications for a public big data storage network accessible to all of humanity.

Naming systems are an important component of any networked information system. It’s difficult to imagine how the Internet could have been adopted by the masses had it not been for the Domain Name System, which translates machine-readable IP addresses into human-readable domain names. Blockchains, with their long and complex address formats, suffer from a similar problem. One might think a solution would be to apply the same naming system architecture we have for the public Internet to public blockchains. But DNS, in the eyes of many, is a largely flawed system. Centrally controlled by the Internet Corporation for Assigned Names and Numbers (ICANN), Internet domain names are vulnerable to censorship and barriers to entry are kept artificially high – registering a new Top Level Domain (ex: .epicenter) costs hundreds of thousands of dollars.
We’re joined by Alex Van de Sande and Nick Johnson to discuss their approach to creating an open, secure and decentralized naming system for the Ethereum Network. The Ethereum Naming System (ENS) allows users to register .eth domain names, which can be used in supporting Ethereum wallets and clients. Names are reserved by placing a deposit in a smart contract and can be mapped to any Ethereum addresses. So rather than sending funds to 0x8cd…0935, one would simply need to type a memorable name like epicenter.eth into their wallet. Backed by the Ethereum Foundation, ENS will likely become the defacto standard for name registration in Ethereum.

The road to mainstream adoption of blockchain technologies is a long one. Although the user experience of wallets has greatly improved since the dark days of command-line only interfaces, decentralized applications continue to struggle with onboarding non-technical users.
Jarrad Hope and Carl Bennetts, join us to discuss Status, a mobile Ethereum client which aims to turn the standard wallet experience on its head. At its core, Status is a mobile instant messenger client that leverages the Whisper protocol for secure peer-to-peer communication. Through its familiar messaging interface and elegant design, users can chat and send Ether directly in the app. As the first implementation of Ethereum’s Light Client Protocol, users may also use decentralized applications such as uPort, Gnosis and Aragon on their mobile phones. Built as an open source project, Status’ developer platform also allows developers to easily port their Dapps to the app.

Anyone who has ever started a company knows just how tedious that process that can be. Whether it’s establishing a shareholder’s agreement, defining the company’s constitutional structure, raising funds, or transferring shares, corporate governance procedures remain largely paper-based, requiring validation from multiple stakeholders, and their lawyers. Blockchain technologies, and specifically smart contracts, provide the rails upon which these processes can be digitized and streamlined, reducing operational costs, eliminating errors and automating menial tasks.
Manu Thanabalan, CTO of Otonomos, joins us to discuss how his company is leveraging smart contracts to accelerate incorporation and automate corporate governance. Otonomos provides the tools and services which allow for anyone to start a company in any of the jurisdictions they support. Using their platform, founders are able to define board members and issue shares, while captables are kept up-to-date in real-time. Day-to-day governance mechanisms and standard procedures such as voting and share transfers are automated through a smart contact, which complies with local jurisdictional regulation.

Years into the great Bitcoin scaling debate no solution is in reach. Neither bigger blocks nor Segregated Witness have anywhere near consensus support. With the conflict escalating, a Bitcoin fork has become a real possibility.
Electrum Developer Thomas Voegtlin joined us to discuss the state of the Bitcoin scaling debate. We discussed Bitcoin Unlimited, ASICBoost, SegWit activation without miner support and how a Bitcoin fork could play out. Possible outcomes include that Bitcoin Unlimited gains a majority of hashing power and starts mining bigger blocks. In the event of a fork, a proof-of-work change could be done to defend the minority chain from miner attacks. And lately a proposal was brought forward to activate SegWit without the support of the hashing power.

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 the commoditization of resources.

Bitcoin and Ethereum miners collectively make up what is perhaps the most powerful computational resource in the world. 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.
