A Decentralized and Collaborative Platform Design for Paid Feedback Service Based on Block-Chain Technology

Ethereum is a recently developed platform technology which can support smart contract and operates based on block-chain technology. The concept of smart contract is to provide automatic service program on top of block-chain, and plays the roles of ensuring the execution of contracts’ contents. The execution of smart contract is open and transparent, and therefore can reduce the uncertainty of transaction. There is also the ERC standard for the digital token, and enables the compensations after fulfillment of contracts. Smart contract is also capable of interflowing with digital wallet, digital exchange，or other smart contracts' tokens.The proposed proposal is to develop a decentralized and collaborative platform for paid feedback service, and the design is based on Ethereum's smart contract. Every user can make a request of service with promised compensations of digital token, or providing solutions to earn contracts’ compensation. Valuable services are therefore circulated in this platform. The mutual trusts among all participants are ensured by the underlying decentralized block-chain technology. The usually disadvantaged participants, from unequal information acquirement, can now become more active without the hesitation.
