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.

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.

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.

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.

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.

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.

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.

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 contract programming language development, and formal verification efforts in the blockchain space.
We also cover his efforts to express the Ethereum virtual machine using the K framework, and to develop a new virtual machine technology, called IELE, specifically tailored to the blockchain space. Check out the episode to understand a game changing technology in the formal verification and smart contract safety space.

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 use of this technology.
In this episode, we are joined by Dr. Amrit Kumar and Dr. Ilya Sergey to discuss Scilla, the smart contract language of the upcoming Zilliqa blockchain. In a previous episode, we’ve already covered the vision and technical approach of Zilliqa to solve the transaction scalability problem of permissionless blockchains. This episode focuses specifically on their smart contract language development efforts.

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.
