Sergio Demian Lerner is a pioneering Bitcoin L2 researcher. As early as 2012, he proposed P2PTradeX, the idea behind all validating bridges. In 2016 he designed the Rootstock sidechain, including its merge-mining subsystem, and bridge, which then he helped transform into the current Powpeg, one of the first HSM-secured federated bridges. He also published the first drivechain BIP, and discovered a critical Bitcoin vulnerability affecting many Bitcoin bridges: the Merkle node type confusion. He designed the Hawkclient, a validating bridge between Rootstock and Ethereum in the PoW era. Currently he is part of the team that develops the new BitVMX disputable computing platform, a key component for building more decentralized Bitcoin bridges. As an entrepreneur, he co-founded several crypto-tech companies such as RSK Labs, Coinspect and Fairgate Labs.
