Eric Larchevêque: Ledger – How to Build an Industry-Leading Cryptocurrency Security Company
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 the company managed to scale without imploding

Grigore Rosu: The K Framework – A Framework to Formally Define All Programming Languages
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.
Topics covered in this episode:
Grigore’s background with NASA and work on formally verified correct software
Motivations to develop K framework
Basic principles behind the operation of K framework
How K deals with undefined behavior / ambiguities in a language definition
The intersection of K framework and smart contract technology
Runtime Verification’s collaboration with Cardano
KEVM and IELE, smart contract virtual machines developed by Runtime Verification
Broader implications of the K framework for the blockchain industry

Amrit Kumar & Dr.Ilya Sergey: Scilla – A Formal Verification Oriented Contract Language
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.
Topics covered in this episode:
Updated on Zilliqa’s progress since our last episode
The technology of mechanised proofs
Dr. Ilya Serger’s effort to mechanically prove safety properties of a blockchain consensus network
Aims of the Scilla language
Future capabilities enabled by the Scilla language
Developer experience and perspective using formal verification tools
How Scilla compares to Michelson, Tezos’ approach to smart contract languages with a similar end goal
Current state of development of Scilla, and next milestones
