ConsensusLab

ConsensusLab’s vision is to be the go-to place for scalable decentralised consensus research. In the true spirit of Protocol Labs Research, we aim to become a hub for the collaborative advancement of human knowledge on this challenging topic. Together with a wide network of academic and industry partners, and in collaboration with other open projects, our team will be building an engine for the decentralised web.

Winkle: foiling long-range attacks in proof-of-stake systems
Winkle protects any validator-based byzantine fault tolerant consensus mechanisms, such as those used in modern Proof-of-Stake blockchains, against long-range attacks where old validators’ signature keys get compromised. Winkle is a decentralized secondary layer of client-based validation, where a client includes a single additional field into a transaction that they sign: a hash of the previously sequenced block.

SoK: Tools for game theoretic models of security for cryptocurrencies
Cryptocurrencies have garnered much attention in recent years, both from the academic community and industry. One interesting aspect of cryptocurrencies is their explicit consideration of incentives at the protocol level, which has motivated a large body of work, yet many open problems still exist and current systems rarely deal with incentive related problems well.

ConsensusLab: supercharging our consensus research
We are excited to announce the launch of ConsensusLab, a new research group focused on scalable consensus for decentralised systems and a part of Protocol Labs Research. Consensus — loosely defined as global agreement on the state of a decentralised network across its mutually untrusting participants — has been known to be at the heart of decentralised systems ever since the inception of Nakamoto’s Proof-of-Work (PoW) consensus.

Marko Vukolić joins PL Research as ConsensusLab Lead
Protocol Labs Research is excited to announce that Marko Vukolić is joining us to establish and lead the ConsensusLab, which will explore and develop methods of coordinating distributed systems. We asked Marko why he decided to join PL Research, what he will be working on, and to share his thoughts about future technological developments:
