WORKit is a decentralized ecosystem, where clients can find the most suitable freelancers for their needs and freelancers can be paid for their services through escrow based on smart contracts. WORKIT reduces transaction costs and realizes fair distribution by overcoming the shortcomings of the existing platform economy through decentralization and de-monopolization. In a protocol economic system, market participants are free to create and participate in certain rules (protocols). In the on-demand decentralized WORKIT ecosystem, freelancers are guaranteed to be paid for services through escrow based on smart contracts, and clients' funds are safely preserved until freelancers complete mutually agreed-upon tasks.
