EB119 – Adam Gibson: A New Kind Of Auditing - Cryptographic Proof Of Online Accounts
Support the show, consider donating: 1E4wyGGWVanUqbGxZvy3PTg2FtxSre7YqX (http://bit.ly/1PMCqNV)
A pioneering feature of Bitcoin is verifiability of transactions: It is designed to enable low-power devices and high end computers alike to be able to verify occurrences on the blockchain.
This observation led our guest, Adam Gibson, to wonder why webpages aren't so easily verifiable as a Bitcoin transaction? Can I prove to you that I have certain bank account balance over the internet? Why do we submit photocopies of passports rather than furnishing a cryptographically verifiable proof of citizenship by logging on to a Government site?
Born out of this intellectual itch is the TLS Notary protocol. It pioneers a new kind of auditing that enables participants to prove that a certain https page was in their browser. This protocol paves the way to brilliant designs for Proof of Reserves, Smart contract oracles and Decentralised fiat-to-bitcoin exchange.
Topics covered included:
- Why is the current Web structured to be not easily verifiable?
- What is TLS and how does it work?
- How TLS differs from SSL.
- The TLS Notary protocol
- Capabilities and limitations of TLS Notary.
- Applications of TLS Notary including provably honest smart contract oracles.

In their relatively short lifespan, blockchain technologies have already undergone significant milestones. Bitcoin’s blockchain, often referred to as Blockchain 1.0, features a simple database ledger that records transactions in a chronological order and represents the state of the network to participants. Ethereum, or Blockchain 2.0, introduced the notion of smart contracts. Microsoft’s Bletchley Project introduces a new modular architecture which might mark a new milestone for blockchain technologies.
Marley Gray, Principal Program Manager Blockchain at Microsoft, joins us to talk about Microsoft’s approach to blockchain architecture. With enterprise in mind, Bletchley introduces the concept of “Cryptlets”, the core building blocks for introducing a secure middleware tier into blockchain application infrastructure. These computational units, running off-chain, on secure trusted container enclave hardware, could provide trusted data to on-chain smart contract logic.
Topics discussed in this episode:
- Marley’s background and experience at Microsoft
- Why Microsoft is aggressively pursuing blockchain technologies (compared to other large tech companies like Amazon, Google, Facebook, etc)
- Microsoft’s Azure Blockchain-as-a-Service offering
- Project Bletchley, its goals and the problems it is trying to address
- The primary use cases in which Bletchley may provide value
- How Bletchley addresses the issue of deploying consortium style blockchains
- What are Cryptlets and how do they relate to Bletchley
- How Cryptlets are different from Oracles
- How Cryptlets could provide data to Ethereum-style smart contracts

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.
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

I caught up with Jamie Burke and Aron van Ammers, who are exploring a really cool direction - credit unions built using smart contracts.
Credit Unions are organisations that match borrowers and lenders that have some level of mutual trust - for example connecting alumni of a university who have liquidity with current students needing liquidity (loans).
We explore how smart contracts could enable the next generation of credit unions through themes such as:
Current challenges with credit unions - underutilisation of capital, governance challenges.
Advantages of moving to a smart contract architecture.
Participants and design of money circle.
Potential challenges with the idea.
The team behind Money Circles.
Check out the video to get an appreciation of how global jurisdiction independent blockchains and smart contracts could enable normal people to better achieve their financial aims and build a better society.

When Robin Hanson invented the concept of prediction markets almost thirty years ago, he felt he had stumbled on a concept with huge implications. By allowing people to bet on the likelihood of future events, prediction markets promise to allow better forecasts and better decision making.
Research into the area has been vibrant, culminating in Hanson's concept of Futarchy: A prediction-market based governance system. At the same time, the real-world applications have been few and far.
Hanson, an associate professor of economics at George Mason University, joined us to discuss his invention, futarchy and the challenges of disruptive technology.
Topics covered included:
- How prediction markets can surface information
- The history of prediction markets
- How futarchy works
- Whether futarchy could settle the blocksize debate
- Why prediction markets failed to get wide adoption
- How Bitcoin is facing a similar adoption challenge

Levin Keller is known to many in Berlin as the man who warned everyone about the dark scenario where buying Bitcoins in Europe would be subject to VAT. As with the VAT issue, Levin was also concerned with the complexity of filing tax returns. For merchants and companies dealing in Bitcoin, keeping track of gains and losses makes proper accounting a messy ordeal.
His startups, Coyno, hopes to solve that by providing standalone, read-only bookkeeping for your existing wallets. Coyno allows you to import the public seed from your HD wallet and keeps track of transactions. The service, currently in beta, reads your wallets' public addresses and stores bookkeeping information whenever a transaction occurs. By recording the exchange rate at the time of transaction, Coyno can generate reports of taxable events, allowing users to more easily file their taxes. By allowing Coyno to read all your wallets, it's able to differentiate incoming and outgoing transaction from funds being moved within your organization, a feature lacking from other reporting tools.
Levin also talks about his journey of being incubated at the Axel Springer Plug and Play Accelerator in Berlin. He also weighs in on some of the challenges of building a Bitcoin startup and attracting investors in Europe.

What Bitcoin did for money, OpenBazaar is trying to achieve for commerce. Born as a fork of the Dark Market project, OpenBazaar aims to facilitate online trade by removing unneeded middlemen. Built as an open source protocol, users simply install the application on their computer to gain access to marketplaces available on the network. From the app, they may also place items or services for sale by creating ""Ricardian contracts"", which get propagated to the network and made accessible to everyone to see. The protocol, which uses Bitcoin as a means of payments, utilises multi-signature transactions. This makes it possible for transacting parties to include third-party arbitrators, who may intervene in the event of a dispute. We talked to Brian Hoffman, the project's Lead Developer, about this paradigm-shifting project and the potential it has to disrupt person-to-person marketplaces such as eBay. Currently in beta, OpenBazaar is due for a full release in Q1-Q2 of 2015.
Topics we discussed:
- History and current status of the project
- Mechanics of a simple transaction on OpenBazaar
- Ricardian contracts
- OpenBazaar's proposed arbitration model
- Reputation and the important role it plays in peer-to-peer trading
- Business models that may be threatened by this technology
