A 2020 perspective on “A fair contract signing protocol with blockchain support”

摘要

The development of the blockchain with its different virtues (decentralized trust, auditability, accessibility, immutability of their operations, etc.) has allowed centralized applications to find a solution to their problems, such as trust, scalability, etc. One of these applications is the electronic signature of contracts which is a key point for the deployment of electronic transactions in the field of e-commerce. We have used the blockchain for contract-signing to avoid the use of centralized trusted third-parties, in a simple way, and where the use of any blockchain solution, allowing data to be published at a reasonable cost, can be easily integrated in our proposal, involving Bitcoin-based solutions (e.g., Litecoin or Dash) or Ethereum. Our results can help other authors to consider more factors, and not just the technological aspects, when selecting a blockchain solution.
