Abstract
Encointer is a cryptocurrency using a novel consensus mechanism called Proof-
Of-Personhood which is based on people meeting physically at regular intervals
in order to attest each other's personhood. After having a digital identity which
is provably linked to a real human being, each user receives a universal basic
income in one of Encointer's local community currencies. The protocol requires
complex logic to be calculated on the blockchain like verifying geolocations or
assigning users to meetups in order to guarantee the security of the system. To
ensure Encointer's scalability to a large number of users it is crucial that those
computations are as e cient as possible which is not yet the case. In this thesis
we present solutions to three major scalability problems of Encointer, evaluate
them in terms of runtime and security and provide implementations that are
ready to be merged into Encointer's production system. Show more
