Brave R&D: THEMIS: Progressive Decentralization with Smart Contracts and Sidechains (Part 2)

In the first blog post of this series, we presented a straw-man version (StrawTHEMIS) of THEMIS. THEMIS is a decentralized ad platform designed by the Brave Research team. We described (i) how a user is rewarded for the interactions with ads, and (ii) how an advertiser can verify the integrity of the billing and performance reporting of their ad campaigns. 

However, StrawTHEMIS does not provide all the properties we aim to achieve, particularly in terms of trust. The design of StrawTHEMIS  requires a centralized entity (called the campaign manager) which is entrusted with the task of orchestrating the running of the underlying protocol. Moreover, there are no mechanisms to enforce or verify the integrity and validity of how the campaign manager orchestrates the protocol. Thus, users and advertisers alike need to take it on trust that their policies are respected when the payouts are calculated, a deficiency we tackle as the next stage of progressive decentralization.

In this blog post we present the full version of THEMIS. We explain how the problems mentioned above are addressed and how THEMIS could be used in the context of BAT. First, we introduce the technical concepts required to reason about the protocol. Next, we outline the full THEMIS protocol and each of its phases. We then discuss how BAT could be used to incentivize participants to perform useful work to the network and how misbehaving participants are challenged. In addition, we present an open-source implementation of both client-side and smart contract logic for THEMIS. Finally, we discuss the scalability and performance of the protocol, based on both client-side and end-to-end measurements in production-like environments.
