TOTEM SDK: an open toolset for token controlled computation managed by blockchain

Abstract

As a part of using the Internet, surging over the past decade, a wide range of data has been generated at a breakneck pace from various sources such as social media, banking sectors and governments. Many organizations have changed their work culture and adopted Big Data analytic to gain various benefits from the data being produced. Nevertheless, sharing this big data was always a tremendous challenge for scientists and engineers as it involves a large volume and sensitive data, which cannot be handled by the conventional way of data analysis. TOTEM: Token for controlled computation, accounts for an innovative concept that integrates both blockchain technologies and big data systems and uses their advantages to present a better, secure and more cost-effective solution for both data owners and data consumers. The TOTEM architecture (US Patent No.: US11,121,874 B2) aims to overcome security and privacy breaches and prevent moving large data sets across the network for analysis. Totem is an entity used in TOTEM architecture for putting constraints on computational operations. Authorised users in the network are allowed to write their own code in a specific format through a TOTEM defined SDK for analysing the data provided by the data owner. The SDK, along with the deployed smart contracts in the network, form a pre monitoring system that keeps track of totem entity value associated with each users’ submitted codes using an estimator table. In this article, we will focus on the layers of this TOTEM defined SDK and further explain how the SDK interacts with the code, analyze it within the layers and finally how it responds to it.
