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.

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 🚀
