b"Asset Transfer Sample for Azure Blockchain Workbench\n====================================================\n\nOverview\n---------\n\nThe asset transfer smart contract covers the scenario for buying and selling\nhigh value assets, which require an inspector and appraiser. Sellers can list\ntheir assets by instantiating an asset transfer smart contract. Buyers can make\noffers by taking an action on the smart contract, and other parties can take\nactions to inspect or appraise the asset. Once the asset is marked both\ninspected and appraised, the buyer and seller will confirm the sale again before\nthe contract is set to complete. At each point in the process, all participants\nhave visibility into the state of the contract as it is updated.\n\n\n\nThere are four personas in this demo contract \xe2\x80\x93 the seller as the initiator, and\nthe other three personas (buyer, appraiser, and inspector) as participants. As\nindicated in the visual above, at certain stages in the contract, there are\nvarious actions which participants can take. The logic written in the smart\ncontract will modify the state accordingly based on which actions are taken.\n\n

\n\nWorkflow Details\n----------------\n\n\n\nThe following state transition diagram articulates the possible flows, and the\nvarious transition functions at each state. Each user is only allowed to take\ncertain actions depending on the application role. Instance roles indicate that\nonly the user with the application role assigned to the specific contract is\nable to take actions on the contract.\n\nThe happy path highlighted shows in a given asset transfer contract, an instance\nowner can place an asset up for sale, and a potential buyer can place an\noffer.\xe2\x80\xafThe two parties can negotiate and once an offer amount is agreed upon, an\ninspector and an\xe2\x80\xafappraiser\xe2\x80\xafworking for the instance buyer will\nparticipate.\xe2\x80\xafAfter their involvement, the buyer and the owner can choose to move\nforward and ultimately complete the transaction.\n\nApplication Files\n-----------------\n\n[AssetTranfer.sol](https://raw.githubusercontent.com/truffle-box/azure-asset-transfer-box/master/contracts/AssetTransfer.sol)\n"
