A Case Study for Blockchain in Contract: FutureText Prototype for Electronic Contracts Signing and Data Recording

EasyChair Preprint no. 3086

Abstract

This paper proposes a convenient, economical and environmentally friendly way to complete the Privately Offered Fund contracts based on shared permission blockchain. There are three main contributions of applying blockchain technology into the contracts. First, in order to reduce the CO2 emission from printing, delivery and mostly for the sake of security, we present an electronic procedure for signing and keeping the Privately Offered Fund Contracts. Second, we design and implement FutureText prototype using Hyperchain, which helps us share privacy information among stakeholders while keeping forged signature, counterfeited seal and twin-contracts away. Finally, to follow the legitimacy and compliance, we put forward methods for both authentication and signature of tripartite contracts. Besides, we put encrypted contracts on blockchain while keeping original contracts on local hosts using heterogeneous storage, and that helps to alleviate the storage pressure on blockchain.

Keyphrases: Authentication, Blockchain, electronic contract, heterogeneous storage, tripartite signature
