Beyond the entrepreneurial activity Martin has done research on the economic incentive structure of different consensus mechanisms and scalability solutions via state channels. Martin co-hosts the Ethereum meetup groups in the Silicon Valley and San Francisco. Finally, Martin is well known for his work and research on “basic income on the blockchain: Circles” - a new currency built on top of Ethereum that aims to implement a basic income as monetary policy.
