A general peer-to-peer based distributed computation network

Abstract

We consider how a decentralised computation system would work when each participant could create computation code as well as executing other participants’ code. A protocol is proposed that allows such collaboration to take place, assuming that no participant can be trusted. We consider briefly how the computation code itself can be executed in a safe manner. The primary focus of this thesis is to investigate how to increase the reliability of the computation results, as some participants can be assumed to return incorrect results. Furthermore, a prototype that demonstrates the key principles of the theoretical results is also developed. The methods developed are found to be correct and working, but unfortunately does not contribute very much in terms of functionality or advantages for the end user.
