Reto Trinkler & Mona El Isa: The Polkadot Protocol - One Blockchain To Connect Them All (158)
Support the show, consider donating: 145PoPHFLFYTTRe1wMZtdzYqsgptgfTKmY (http://bit.ly/2fWcvKF)
System scalability and extensibility of system features are two central problems around which research in the cryptocurrency / blockchain industry has centered. For example, the Blockstream sidechains project foresaw hundreds of blockchains coordinating together to form an ‘Internet of Chains’ delivering extensibility to the Bitcoin system.
Recently, Dr. Gavin Wood, co-founder of Ethereum and Parity, put forth Polkadot, a technical vision to achieve the similar end-goals using different system architecture. Polkadot could enable individual blockchain networks to share security and communications infrastructure with other blockchain networks, forming in effect an ‘Internet of Blockchain networks’.
Melonport, a team based out of Zurich, has taken up the challenge of deploying the Polkadot network and also building decentralized asset management software on the same network. In this episode we converse with Mona El Isa and Reto Trinkler, co-founders of Melonport, in order to discover more about the overall vision.

In the crowded race to become the leading ‘Bitcoin 2.0’ platform, Counterparty has stood out by avoiding fancy crowdsales and instead building a platform that works. The protocol, which sits on top of Bitcoin and thus benefits from the security of its mining power, allows issuing assets, paying dividends or trading in a decentralized way. Over the past year, it has been the platform of choice for many crowdsales and is also what powers LTBCoin.
Co-Founder Robby Dermody joined us for a discussion of the features and evolution of the project.
Topics covered included:
- Why they create the initial XCP supply by destroying bitcoins
- What the different components of the Counterparty system are
- What distinguishes embedded consensus systems like Counterparty
- Why crowdfunding has become a major use case for Counterparty
- Why Counterparty’s Ethereum-style smart contracts will play an important role in the future
- Their new company Symbiont, which aims to commercialize Counterparty's technology

When Jed McCaleb discovered Bitcoin, there didn't even exist an online marketplace to trade the cryptocurrency yet. The experienced founder who had earlier started file sharing site eDonkey, acted fast and started the first Bitcoin exchange MtGox which he later sold to now-infamous Mark Karpeles. Jed later founded the pioneering Ripple project before leaving to start Stellar.
We discussed his journey through the industry and the ambitious plans Stellar has to create an open financial system that will give access to financial services to a much broader spectrum of humanity.
Topics covered included:
- Jed's early involvement in the industry and founding of MtGox and subsequently Ripple
- Why Jed left Ripple and started Stellar
- How Ripple and Stellar differ
- The Stellar Consensus Protocol
- Why the organization behind Stellar is a non-profit foundation
- Stellar's focus on developing markets and Nigeria in particular

One of the shortcomings of decentralized smart contracts is their inability to retrieve information from the outside world. 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

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

It's a project as audacious as any we've had on the podcast and Juan did an outstanding job explaining the technology and vision.
Topics covered included:
- Why HTTP is broken and how IPFS could complement and ultimately replace it
- The different technologies IPFS is based on including DHT, Git, Bittorrent and SFS
- How IPFS could enable the 'permanent web' by distributing file storage
- Content-addressing and how hosting works on IPFS
- Mutable content and the Interplanetary Naming System (IPNS)
- Filecoin and incentivizing hosting on IPFS
- Why IPFS is a great fit for smart contracts
- How he wants to build and monetize core internet protocols with his company Protocol Labs
