Digital points are currently widely used as a means of sales promotion by business parties. However, different business and enterprises issue different point assets respectively, the established point rules are different, the attraction of points to users is gradually reduced due to the problems of inconvenient point inquiry, complicated exchange process, over-dispersion, high exchange difficulty and the like in the process of using the points by users, the exchange rate of the existing points is low, and the business side establishes a gift bank and operates and manages a point platform and consumes a great deal of energy but does not achieve the expected target.
The method aims at the problems that the prior point application is opaque in distribution, not universal in dispersion, incapable of transferring and the like. The block chain technology which has emerged in two years depends on the characteristics of a unique consensus mechanism, non-tamper property, intelligent contracts and the like, if the block chain technology can be applied to digital point service, points of different business parties can be exchanged into the communication assets on the block chain, the digital asset communication of the business parties and users is realized, and three pain points of 'scattering, small and unavailable' of the current points are solved. The method can provide convenience for the user, meanwhile, the goal of enhancing user stickiness of a business side is achieved, and more potential users are brought to enterprises.
At present, most of digital asset exchange based on the blockchain technology is accepted through a centralized exchange, while decentralized asset exchange is decentralized exchange in a constantly atomic transaction mode, and point-to-point (P2P) exchange of two digital assets on different blockchains is promoted through an intelligent contract technology, so that the requirement on a centralized intermediary is eliminated. This approach is mostly used for cross-chain asset exchanges, but it is limited to atomic exchange object encryption algorithms, and the underlying blockchain of the public-chain asset exchange must be compatible with HTLCs (hash time lock contracts) and can accommodate additional programming functions. The HTLC atomic exchange method of the alliance chain needs to carry out the cooperation of exchange reasons through a centralized cross-chain component, but the transaction fault is easily caused by too many flows, and the transaction duration is longer.
In summary, those skilled in the art propose a method for digital asset redemption based on blockchain technology.

the first stage comprises that a user submits a conversion request to a platform, the platform checks whether the balance of the user is sufficient, and simultaneously checks and judges whether a user object receiving the asset has a digital asset wallet of an asset issuing business party;
the second stage comprises the steps that the user transfers money to the asset issuing business party at the wallet of the asset exchanging business party;
and the third stage comprises the steps that the asset issuing business party issues the digital assets to the asset receiving user of the business party, and the issued amount is the exchange rate converted amount after the exchange business party transfers the money of the wallet of the issuing business party.
Further, in the first stage, after the user submits the exchange request, the exchange service is suspended without transfer operation under the condition that the balance is insufficient or the receiving party does not have a corresponding wallet.
Further, in the second stage, the background task regularly scans the digital asset exchange task execution state of the state table and retries the error stage.
Further, in the second stage, after the deduction service is successfully exchanged, the service party performs uplink recording on the digital asset outflow.
Furthermore, in the third stage, the execution state of the first stage is confirmed again by scanning the transaction table, and if the first stage cannot be executed, the service is terminated without performing transfer operation.
Further, in the third stage, after the service is successfully issued, the service party performs uplink recording on the digital asset inflow.
Further, the reconciliation mode of the digital asset comprises:
exporting the outflow rate, the outflow quantity, the exchange quantity and the cost net value in the outflow/inflow record table of each business party;
and acquiring the balance of the refund purse stored on the blockchain by each service party.
