Collaborative Smart Contracts (CoSC): example of real estate purchase and sale(s)

The emergence of blockchain technology has opened up opportunities for innovative solutions in various fields. One of these solutions is the concept of smart contracts(SCs), which can automate the execution of contract terms and conditions. In this paper, we introduce Collaborative Smart Contracts (CoSC), a novel approach that combines the benefits of smart contracts and collaborative decision-making. CoSC allows multiple parties to participate in the contract execution process, enabling a more transparent and fair system. We present an example of the application of CoSC in the real estate industry, specifically in the purchase and sale of properties. Our proposed approach utilizes a consortium blockchain network to create a secure and decentralized environment for CoSC. The CoSC platform facilitates communication, collaboration, and decision-making between the buyer, seller, and other relevant parties involved in the transaction. We evaluate the performance of the CoSC platform in terms of execution time, benefits, and security. With the CoSC platform, an average of 20+% success is achieved in terms of execution time. Our results demonstrate that CoSC is a promising solution for complex, multi-party transactions and can improve the efficiency, transparency, and trustworthiness of the real estate industry.
