【Introduction of the smart contract for Public Procurement 】

  • This is a smart contract in order to realize a highly transparent public procurement (tender & bid).
  • Split a large contract into several small contracts. (and they are managed with NFTs)

 

【Workflow】

  • ① A project is created by a project owner (e.g. Goverment, etc...)
    • smart contract publish NFTs for each project (bit & tender)

  • ② Bidders submit proposal of conditions for a project owner.

  • ③ Once a proposal is chosen, a project owner submit a contract agreement with a chosen bidder.
    • smart contract publish NFTs for each contract （in order to identify owner of each contracts） => Each NFT is associated with IPFS backed contract agreement.

  • ④ A project owner (e.g. Goverment, etc...) deposit money for the best bidder.
