The Tezos whitepaper, published in 2014, anticipated several areas that would become major issues for blockchain networks. Especially around governance and smart contract security, Tezos proposed original solutions. The project later went on to raise $232m in the biggest token sale at the time. Recently, the Tezos network launched as the first of a wave of innovative next-generation blockchain networks.
We were joined by Tezos co-founders Arthur and Kathleen Breitman to discuss the history of the project, how the network functions today and how it could develop going forward.

Public blockchains produce enormous amounts of data. In theory, anyone can access the raw contents of transaction and blocks. In practice, however, querying blockchains can prove to be a daunting task.
The difficulty lies in the fact that blockchains are particular types of distributed databases and thus carry several limitations. Most, if not all, blockchains lack the most basic SQL querying capabilities supported by nearly every off-the-shelf database system.
Take Bitcoin as an example. Its API lacks even the most basic calls which would allow a user to query any address and receive the balance. In order to achieve this, block explorers and alike have developed sophisticated middleware infrastructure that parses the blockchain, normalizes the data, and stores it in a database, where it can be queried. In the best of cases, companies offer API calls for only a limited set of operations. Google hopes to change this by freeing blockchain datasets.
We’re joined by Allen Day, Science Advocate at Google’s Singapore office. Earlier this year, he and his team released the Bitcoin blockchain as a public dataset in Big Query, Google big data IaaS offering. In August, they added Ethereum to their list of freely available public datasets, which includes US census data, cannabis genomes, and the entirety of Reddit and Github. Anyone wishing to query the data can do so in SQL on the Big Query website or via an API. For instance, a relatively simple query would return the daily mean transaction fees since the Genesis Block in just a few seconds.
Coupled with Google’s AI and Machine Learning infrastructure and other open data sets, one can only imagine the potentially groundbreaking insights we could gain from this data.

The expectation has become widespread that blockchains will end up underpinning major societal infrastructures. The narrative in the blockchain space is that networks are decentralized and trustless and thus regulation should not apply to networks directly. Legal scholar Angela C. Walch has been questioning terms like decentralization and trustlessness and argues that blockchains shift the need for trust rather than remove it. Her controversial ideas include that key developers of open-source project should be treated as fiduciaries and held accountable for the consequences of their work.
Angela Walch is a professor of law at St Mary University School of Law and a Research Fellow at the Center for Blockchain at UCL. She is a graduate of Harvard College and Harvard Law School and has been doing academic work on legal issues surrounding public blockchains since 2013.

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.

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.

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.

Since he started blogging as Two Bit Idiot in 2013, Ryan Selkis has been both industry insider and industry critic. Consistently calling out excesses and abuses, but also maintaining his sights on the long-term potential.
He recently founded Messari, a project that aims to bring more transparency and fairness to the industry. Messari has narrowed in on siloed, inaccurate and incomplete data as a key factor that allows insiders to profit at the expense of the public. We talked about the various ways in which Messari tackles that problem, ranging from a community-led effort to gather project data to the ambitious goal of a token-curated registry of stand-up projects.
