Epicenter - Learn About Blockchain, Ethereum, Bitcoin And Distributed Technologies

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 C

We are joined by Ryan Zurrer, Principal and Venture partner, at Polychain capital. Polychain capital is a breakout crypto hedge fund with over $100 million in assets under management, and large investments in major crypto projects such as Dfinity, Polkadot, Filecoin and Vest. Ryan was the first person to join Olaf Carlson Wee in managing this fund. He built multiple companies in the wind energy industry prior to making a switch to the cryptocurrencies. In this episode, we go behind the scenes of the Polychain success story. We get details on what crypto hedge funds are, how Polychain got started, reasons for its breakout success, its approach to blockchain investments and the current challenges of running a crypto hedge fund. Ryan also walks us through Polychain’s interest areas – Layer 1 blockchain protocols such as Filecoin, Dfinity and Polkadot; and financial derivative protocols. If you want to understand how some of the leading minds allocate capital at a large scale in the cryptocurrency industry, check

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 enable

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. Topics covered in this episode: Ryan’s start into the crypto industry as pseudonymous blogger Two Bit Idiot His insights from being the Digital Currency Group’s first employee CoinDesk and the challenges of journalism in crypto Why poor and inaccurate information benefits industry insiders at the expense of retail investors Messari’s mission to le

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

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 de

The 2016 Ethereum hard fork left us with two distinct Ethereum chains. While the main Ethereum chain dwarfs Ethereum Classic in terms of market cap, ETC has sustained its position as a significant actor in the broader blockchain ecosystem. ETC’s recent listing on Coinbase demonstrates its credibility as a significant industry player. We’re joined by Anthony Lusardi, Director of the Ethereum Classic Cooperative, an organization who’s goal is to promote the development of the Ethereum Classic Network. Similarly to other industry organizations, The Cooperative invests in core development of the ETC blockchain, community building, marketing, and brand awareness. Topics covered in this episode: Anthony’s background and how he became involved in the crypto community The Ethereum Classic Cooperative and the goals of the organization What the ETC ecosystem looks like two years after the fork The people and companies contributing to the project and building on the platform The overlap and friction points with the bro

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 decent

When the Bitcoin Foundation fell apart and funding for Bitcoin core development was needed, the MIT founded the Digital Currency Initiative to step in. In the years since, the DCI has evolved into a vibrant center of cutting edge research on some of the most difficult challenges around blockchain technology. DCI Director Neha Narula joined us to discuss the DCI’s position between academia and industry, their policy on conflicts of interest, and their most fascinating research topics. Topics covered in this episode: How her interest in distributed systems and scaling lead led her to the blockchain space The mission and history of the MIT’s Digital Currency Initiative How cryptocurrency might evolve over time as an academic field The DCI’s project on digital fiat currency How zkLedger could enable privacy-preserving auditing for distributed ledgers Why sharding is unlikely to succeed in the short- and medium term Why Neha is most optimistic about layer 2 approaches to scaling like lightning network The story o

Before founding what is now one of the most successful companies in the cryptocurrency industry, Eric Larchevêque and his co-founder opened La Maison du Bitcoin, a Bitcoin education center and co-working space in the second district of Paris. It was through chance encounters in this space that Leger was born in the basement of 35 rue du Caire, where the company also operated a Bitcoin exchange desk and a handful of crypto miners. Eric Larchevêque, CEO of Ledger, joins us again since his last appearance as a guest 200 episodes ago. We discuss the meteoric rise of Ledger from a ten-person team to now nearly 150 people across three continents. This fascinating discussion is a master class in product development, scaling at lightning speed, and staying true to your vision when everyone is pushing you to change course. Topics covered in this episode: Eric’s background and how he became involved in the Bitcoin space La Maison du Bitcoin and the early days of Ledger in Paris The meteoric growth of Ledger and how th

While many cryptocurrency holders have thought about how to secure their assets, how to pass on cryptoassets in case of one’s death is rarely on people’s mind. Lawyer Pamela Morgan has been helping people and organizations build solutions to safely store their cryptoassets and has recently turned her attention to inheritance planning. Though we have often explored the legal issues surrounding blockchains and cryptocurrencies on Epicenter, never have we discussed the topic of inheritance. We discussed her new book “Cryptoasset Inheritance Planning” and how people can design a simple plan to give heirs a high chance of recovering assets in less than an hour. Topics covered in this episode: How an impassioned talk on Bitcoin by Andreas Antonopoulos started her crypto journey Common misconceptions lawyers have about crypto Her work through Empowered Law on educating lawyers Third Key Solutions and building non-custodial key management solutions The most frequent mistakes people make when it comes to protecting c

In the past few years, we witnessed the development of multiple smart contract languages – Solidity, Viper, Michelson, Scilla etc. These languages need to enable developers to write correct, predictable behavior smart contract code. Each language development effort therefore ends up spending resources into building formal verification toolsets, compilers, debuggers and other developer tools. In this episode, we are joined by Grigore Rosu, Professor of computer science at UIUC (University of Illinois at Urbana-Champaign) for a deep dive into the K framework. The K framework is mathematic logic and language that enables language developers to formally define all programming languages; such as C, Solidity and JavaScript. Once a language is formally specified in the K framework, the framework automatically outputs a range of formal verification toolsets, compilers, debuggers and other developer tools for it. Updates to the language can be made directly in K. This technology has massive implications for smart cont

With the rise of smart contract technology, we’ve become acutely aware of the need for smart contract code to accurately reflect the intentions of its author; and for the code to have certain (safe) behaviors in all circumstances. Creating the languages and software tools to enable ordinary developers to write safe contracts has become an intense research endeavor in the cryptocurrency space. Scilla is a Turing incomplete intermediate level language; inspired from the paradigms of functional programming and formal verification; that makes it easy for smart contract developers to automatically prove statements about smart contract behavior. For example, Scilla could allow a future multi-signature smart contract author to mathematically prove that funds in that contract would always be retrievable by certain addresses (and never get stuck like the Parity incident). The ability to mathematically prove such safety properties of the smart contract has the potential to be an enabling invention prior to widescale us

As a society, we have organized as tribes, hierarchies, and markets to accomplish the most impressive of achievements. Human cooperation and collective organization are present at nearly every significant milestone in the history of human civilization. As we move towards an increasingly connected and automated society and economy, there will become a need for decentralized infrastructure which enables companies and markets to make fast decisions at scale. We’re joined by Matan Field, CEO of DAOstack, a new platform that aims to become the operating system for collective intelligence. DAOstack is building a toolset to allow decentralized governance and building self-organizing collectives at scale. Topics covered in this episode: Matan’s background and journey since founding Backfeed What is a DAO and the necessary components to create a functional DAO The role of DAOs in today’s society and over the long-term DAOstack as “WordPress for DAOs” The different layers of DAOstack and their respective roles Hologra

With the advent of mature quantum technologies, many of the critical cryptographic protocols which secure the Internet, financial transactions and even military secrets may become susceptible to new attack vectors. For instance, while it may take a computer millions of years to decipher a public key’s corresponding private key, a sufficiently powerful quantum computer might achieve this in a reasonable amount of time. With this reality looming over us, many in the blockchain space worry that someone with access to a quantum computer might one day have the ability to steal their hard-earned crypto. We’re joined by Ajay Prakash and Gavin Brennen, founders of the Qubit Protocol, a decentralized blockchain-enabled governance protocol that is meant to select and fund the best startups in the quantum world. As a co-author of the recent paper “Quantum attacks on Bitcoin, and how to protect against them,” Gavin walks us through the primary threats that quantum computing poses on Bitcoin. Among the major vulnerabiliti
