Alejandro Ranchal-Pedrosa is a Senior Protocol Researcher at scroll.io, working on improving the security, scalability and cost of the scroll ZK-Rollup for Ethereum. Prior to Scroll, Alejandro worked as a Protocol Researcher at Protocol Labs, primarily focused on providing faster finality for Filecoin through a novel architecture for longest-chain blockchains and a novel BFT consensus protocol designed for fast finality in open systems (F3 and GossiPBFT). At Protocol Labs, Alejandro also worked on providing crypto economic guarantees to Filecoin’s user-spawned subnets that interoperate in the Filecoin ecosystem (IPC), and on designing and implementing a framework for SMR systems (Mir). Before Protocol Labs, Alejandro worked at CEA Paris proposing protocols for scaling payment channels networks, as well as at IMT Paris and UAB Barcelona, where he found two critical attacks common to the Lightning Network and all its implementations. During his PhD at the University of Sydney, he worked on scaling Blockchains through subnets, increasing Blockchains' security through novel faults and game theoretical models, and enhancing Blockchains' decentralization via committee sortition proposing novel random beacon protocols, under the supervision of Vincent Gramoli.

François Garillot is a research engineer with deep experience in blockchain consensus and distributed systems. He was an early contributor to advanced BFT protocols, working on the team that developed and formally verified the Libra (Diem) blockchain’s consensus algorithm. He worked on what is now the Aptos, Flow and Sui blockchains, and was the lead of the consensus team at Mysten into 2023. François has a background in distributed systems, type systems and programming languages. As a blockchain engineer, he has helped design high-throughput, robust networks and is passionate about bridging theory with practice. François is based in Montreal and enjoys pushing the limits of decentralized technology through both research and hands-on engineering.

Gavin is a computer scientist and blockchain developer best known as a co-founder of Ethereum and the creator of Polkadot. He played a crucial role in the early development of Ethereum, designing its smart contract programming language, Solidity, and serving as the project's first Chief Technology Officer (CTO). Wood also wrote the Ethereum Yellow Paper.

Wood founded Parity Technologies, where he developed the Substrate framework and the Polkadot network. Wood is widely recognized as a thought leader in blockchain governance, decentralization, and Web3 technologies.

Dr. Paul Dylan-Ennis (aka polar) is Lecturer/Assistant Professor in the College of Business, University College Dublin. He is the author of Absolute Essentials of Ethereum (Routledge, 2024). He is on the Strategic Council at the Aragon Foundation, co-Organizer of ETHDublin and contributor to CoinDesk.

I'm a Research Engineer mostly interested in designing practical, full-featured, composable, and configurable fault-tolerant replication systems, as well as exploring clear and expressive ways to implement them. I'm also enthusiastic about exploring alternative programming models for distributed computing. I think that decentralized Byzantine-fault tolerant mechanisms should dominate in future computing systems, and I'm very excited about working towards that.

I like to think of myself as someone discovering smart solutions to hard problems and doing this for the common good. In that, I believe in open source, open innovation and collaboration.

This is why I decided to found Replica_IO, an open-source framework for building practical distributed replication mechanisms. If you're also excited about this initiative, feel free to contact me! Let's make a breakthrough in designing and implementing distributed replication protocols for the future of decentralized computing 🚀

I am a software engineer and lead developer for Polkadot.

I started in the Ethereum ecosystem 7 years ago, and have been building on Polkadot for the last 6 years.

Before that, I was working at Microsoft on their Azure Cloud platform.
