Glen Weyl: Radical Markets – Uprooting Capitalism and Democracy for a Just Society
The rise of populism and increasing inequality have led to widespread questioning of democracy and capitalism. Glen Weyl, a political economist and Principal Researcher at Microsoft, along with legal scholar Eric Posner, published a book called ‘Radical Markets’. Radical Markets explores how restructuring property rights and voting systems could lead to more efficient markets and a more just society. Glen joined us to discuss the book and why the blockchain space is a fertile testbed to explore these radical new ideas.
Topics covered in this episode:
Why blockchain is on a trajectory to exacerbate inequality and fail at improving the world
Why property should be seen as a monopolistic institution
How property rights create inefficient markets
The radical idea of transforming property rights via a Common Ownership Self-Assessed Tax (COST)
How the one-person-one-vote system contributed to the crisis of democracy

Clement Lessage & Federico Ast: Kleros – Crowdsourced Arbitration for Blockchain Applications
Dispute resolution is the process by which contracting parties settle disagreements. Whether in the form of litigation, arbitration, or other means of mediation, every contract defines a dispute resolution mechanism and jurisdiction. It is the metaphorical Lady Justice, measuring the strength of each party’s arguments, and reaching a decision based on evidence.
Smart contracts are unique in this sense. Unlike traditional contracts, they are rigid and deterministic. Written in computer code, nuances in human language and vagueness of terms do not exist in this realm. There are no judges, no jury, just calculated execution.
The DOA hack and other similar events have prompted observers of the space to express the need for smart contract dispute resolution. Some have suggested “exit switches” that would allow for human intervention when edge cases appear. But could the arbitration process be integrated into the smart contract and on the blockchain?
We’re joined by, Federico Ast and Clement Lessage, respectively CEO and CTO of Kleros. This dispute resolution layer provides contracting parties with a fast and secure process for arbitration. The system is broken up into courts and sub-courts, each specializing in specific matters like e-commerce, insurance, and transport. In the event of a dispute, parties submit their case to Kleros, where a crowd of expert jurors analyses the evidence. When all votes are cast, the decision is enforced by the smart contract, which may unlock funds, or provide parties with additional time to fulfill the terms of the agreement. Clever incentive mechanisms reward jurors who vote with the crowd, making Kleros resistant to bribe attacks and collusion between jurors.
Topics covered in this episode:
Federico and Clement’s respective backgrounds, including a crowd arbitration project called Jury.
The vision behind Kleros and the problem it addresses
The case for crowd-sourced jurors as a means to find the best judgment
The game theory and incentive mechanisms embedded in Kleros
Kleros’ hierarchical system of courts and sub-courts
How jury selection works and who administers courts
The system’s built-in governance mechanism and its purpose
The Kleros token, Pinkaion coin, and it’s utility in the system
“Doge on Trial,” a clever experiment to find authentic doges
The current status of the project and roadmap

Uri Klarman: bloXroute – Layer-0 Scaling with the Blockchain Distribution Network
Until now, proposals to improve blockchain scalability have addressed the problem in one of two ways. One seeks to increase efficiency by optimizing the blockchain or improving the consensus algorithm. The other comes in the forms of layer-2 solutions such as payment channels or side chains.
However, none have addressed the core bottleneck to scalability: TCP/IP network limitations. Improving the speed at which blocks propagate through the network is the layer-0 problem few people consider when thinking about scaling.
Fundamentally, network bottlenecks are what prevent blockchains from increasing their transaction throughput. Raising the block size or reducing the time between blocks has devastating effects on usability as the probability of a fork increases. At a certain point, the blockchain simply breaks as forks occur faster than blocks can propagate to all validators.
Remarkably, the web figured out how to scale decades ago with the invention of Content Distributions Networks, or CDN. This is what enables platforms like YouTube to steam thousands of hours of video to hundreds of thousands of people every second. However, traditional centralized scaling solutions lack the privacy and censorship resistance necessary to serve the decentralized web.
We’re joined by Uri Klarman, CEO of bloXroute. Founded by a team of researchers and systems designers from Northwestern and Cornel University, including Emin Gün Sirer, bloXroute allows practically every blockchain network to “scale today.”
As a scalability infrastructure service, their Blockchain Distribution Network, or BDN, sits underneath blockchain networks. Anyone operating a miner can use the BDN without any changes to their consensus algorithm or protocol. By simply pointing their software to a bloXroute node, miners immediately benefit from propagation speeds orders of magnitude higher than the time which is currently required for blocks to be seen by all validators. This global network of servers is optimized to receive and stream massive amounts of transaction data to vast networks of nodes and miners.
While bloXroute relies on some level of centralization, it is provably neutral and cannot discriminate based on the contents, provenance or destination of a block. It also includes clever redundancy mechanisms which ensure availability in the event of an attack on the network.
Topics covered in this episode:
Uri’s journey as an academic working in the field of networking
Defining the blockchain scalability problem as a networking problem
Past work and attempts to scale blockchains
The vision behind bloXroute and the problem it aims to solve
The Blockchain Distribution Network (BDN) and its technical architecture

Guy Zyskind: Enigma – Providing Scalable Privacy-Preservation to Smart Contacts
Privacy and scalability are arguably the most challenging issues blockchains face. Scalable privacy-preserving state machines are inherently difficult. While cryptocurrencies like Zcash have proven trustworthy for simple transactions, privacy in smart contract platforms is an entirely different animal.
We’re joined by Guy Zyskind, CEO of Enigma, a platform for scalable decentralized apps which preserves privacy. The Enigma network treats Ethereum smart contracts as “secret contracts” and can perform computations on encrypted data. Inputs are broken into pieces and distributed to network nodes which perform computations on a segment of the full data. Once returned to the Ethreum chain, data is reassembled and may be decrypted to reveal the result. Leveraging secure multi-party computation and Trusted Execution Environments (TEE), Enigma prevents a malicious actor from gaining access to the input data and the computation results.
Topics covered in this episode:
Guy’s background and secure computation research at MIT
The different approaches to privacy preservation in computing
The different multi-party computations methods and how they work
Fully Homomorphic Encryption in the context of MPC
How Enigma would preserve privacy for a simple application like tallying votes
How Enigma reads encrypted data from the Ethereum network and leverages Trusted Execution Environments to perform computations
How developers build smart contracts which use Enigma
The role of the Enigma token as an incentive mechanism
How Enigma ensures network availability by penalizing nodes which go offline
The current state of the project and upcoming milestones

Martin Becze: Primea – The Next-Generation Blockchain Operating System
Martin Becze is a researcher at Dfinity working on a next-generation “Blockchain Operating System” called Primea – a continuation of his work on the eWASM project from his time at the Ethereum Foundation. Primea is an actor based IPC layer intended for use with WebAssembly programs.
Martin first learned about Ethereum in 2014 and was immediately drawn into the possibilities opened by having a contracting virtual machines on a blockchain. While the EVM was impressive, Martin saw the possibility for greater usability and efficiency by using the new WebAssembly standards being created, and so led a team at the Ethereum Foundation in the creation of a new blockchain virtual machine, called eWASM. We learn about Martin’s experience on the eWASM project and how the limitations of backwards compatibility led him to begin writing a brand new execution environment from scratch, rethinking some of the core designs and mechanics of the EVM – this project became known as Primea. Martin explains many of the fundamental design shifts involved with the Primea platform, including his focus on using the actor-based model and object capabilities (and what these even mean!). He also lays out how the Primea platform fits into the larger design of the Dfinity blockchain.
Topics covered in this episode:
eWASM – Ethereum flavored WebAssembly (eWASM) Design.
Primea – an actor based IPC layer intended for use with WebAssembly programs.
Webassembly
Dfinity – blockchain-based cloud computing project. Its aim is to develop a decentralized internet computer that will become the cloud 3.0.

Evan Shapiro & Izaak Meckler: Coda – A Succinct Blockchain
One of the key scalability challenges with public cryptocurrency blockchains is that their size grows linearly with the number of transactions. Mature blockchains such as Bitcoin and Ethereum contain >170GB and >1 TB of historical data respectively. New nodes joining these chains need to download this data and verify it in order to become a “full node”. The number of full nodes is a key measure of decentralization, and difficulty becoming a full node translates into future centralization.
In this episode, we are joined by the duo of Evan Shapiro and Izaak Meckler, CEO and CTO at O(1) Labs respectively. O(1) Labs is a pioneering company that uses zkSNARK technology in order to construct a cryptocurrency blockchain, called Coda, that solves the blockchain size scalability bottleneck. New nodes joining the Coda network will be able to trustlessly boot up in under a minute by verifying cryptographic proofs that attest to the validity of the current chain. This technology has great potential to enable decentralization, and for one blockchain to be a light client of another blockchain.
Topics covered in this episode:
Scalability challenges of current cryptocurrencies
Background on O(1) Labs and their mission statement
How Coda uses succinct computational integrity technology (zkSNARKs) to enable further decentralization of blockchains
Snarky – a domain specific language for zkSNARK computations
