A Blockchain Approach to Support Digital Contracts

Distributing computing that work with policies that flirt with democracy, in which parties can interact without an intermediary, has gained strength. In this way, an attractive idea is to support digital contracts by removing the third party and allowing the group to create and store contracts in a reliable and secure way, where contracts are immutable and easily retrievable. We propose a Blockchain approach to aid the management of digital contracts. The proposal considers contract encryption, digital signature, and protocols for chaining blocks with data related to digital contracts. We develop a prototype to ensure the viability of our proposal. We also present a case of use to demonstrate the prototype usage. We argue that proposal and implementation together create an appropriate environment for research and education purposes.
