Research interest
I study fundamental aspects of permissionless blockchains and cryptocurrencies.
My research mainly combines techniques from Cryptography and Distributed Computing.
Hopefully my PhD thesis will be able to (partly) answer (some of) the following three questions:
- Scalability: How can permissionless blockchains process thousands of transactions per second?
- Decentralisation: How can permissionless blockchains prevent being controlled by a few powerful people/authorities?
- Egalitarianism: How can permissionless blockchains even the voting power of the rich and the poor?
