The "Macle" project consists in the creation of a platform based on blockchain technology, aimed at facilitating the connection between customers and designers for their professional projects. The main objective is to simplify and improve the collaboration process by providing a secure and transparent space for creative transactions and exchanges. "Macle" offers customers the opportunity to publish their projects and describe their specific needs. Designers can then explore available opportunities and offer their services based on their expertise and portfolio. Thanks to blockchain, transactions are secure and information is recorded transparently, reinforcing trust between stakeholders. The "Macle" platform also facilitates the management of contracts, payments and copyrights through the use of smart contracts and payment mechanisms integrated with blockchain. By promoting direct collaboration between customers and designers, "Macle" aims to optimize the efficiency and transparency of the professional creative process. The platform also offers designers the opportunity to build their reputation and expand their professional network by working on a variety of projects.
