All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Fig. 1 is a flowchart illustrating a method for chain anti-cheating on a digital asset, which is suitable for being executed by an electronic device, such as a computer or a server of an owner of the digital asset, according to an exemplary embodiment. As shown in fig. 1, the method comprises the steps of:
S1A, constructing a first multi-signed address for receiving respective verifier signatures. The validator, for example, a property asset, can be, for example, a sales licensor, an environmental report issuing agency, a tenant, a creditor, and so forth.
And S2A, creating transaction information, polling each verifier, and waiting for the verifier signature fed back by each verifier, wherein the verifier signature comprises each compliance process signature. In a preferred embodiment, the transaction information is created without broadcast, indicating that incomplete information is available at the time, and that the data need not be linked.
For example, construct a transaction Tx1{ (a1), (a2),., (An) }, where (a1) represents the signature of the waiting verifier a1, where (a2) represents the signature of the waiting verifier a2, and where (An) represents the signature of the waiting verifier An.
When the verifiers are polled, the verifiers are further polled for compliance process departments that have signature information, such as compliance process A11, A12, A1n for verifier A1. In effect, polling is initiated separately for the verifier's compliance flow, e.g., for verifier A1, the down-chain flow Tx1{ (a11), (a12),. ·, (A1n) } is initiated, where (a11) represents the signature of the waiting compliance flow a11, where (a12) represents the signature of the waiting compliance flow a12, and where (A1n) represents the signature of the waiting compliance flow A1 n.
After each compliance process department carries out signature respectively, the completion is finished (A1), and the signature is fed back to the initiator.
And S3A, obtaining all the signature of the verifier to form complete transaction information. That is, after all the compliance process signatures of all the verifiers are obtained, complete transaction information is formed and the uplink is completed.
In an alternative embodiment, the broadcast is done as soon as this step is completed. Therefore, the real-time performance of data chaining can be improved, and the whole network can immediately know that the digital assets are chained.
In another alternative embodiment, the broadcast is not performed at the completion of this step, and the transaction to construct the asset transfer is awaited until the broadcast is performed after the asset transfer is completed. This can reduce the amount of calculation and reduce the economic cost.
According to the digital asset uplink anti-cheating method provided by the embodiment of the invention, when digital asset transactions need to be linked, a multi-signature address is constructed and a transaction is created, then each verifier is polled until all compliance process signatures of all verifiers can be obtained to finish data uplink, and each compliance process of the verifier is added to the uplink process, so that the authenticity of data can be ensured.
After the step S3A, when the digital asset owner needs to cancel the transaction, the method may further include the following steps:
S4A, polling each verifier, and waiting for the verifier signature fed back by each verifier, wherein the verifier signature comprises each compliance process signature;
S5A, when all the verifier signatures are obtained, canceling the transaction information.
According to the above scheme, if the owner of the digitized asset wishes to chain down the asset, the transaction is cancelled by polling the various validators, entering a signature confirmation, and never broadcasting the transaction, even if the broadcast fails according to the characteristics of the blockchain.

Optionally, the polling unit 22 is further configured to poll each verifier when the digital asset owner needs to cancel the transaction, and wait for the verifier signature fed back by each verifier, where the verifier signature includes each compliance process signature;
the transaction composing unit 23 is further configured to cancel the transaction information when all the verifier signatures are obtained.
Optionally, the broadcast is not made when the digital asset owner creates the transaction.
Optionally, the broadcast is done while composing the complete transaction information.
Optionally, when the complete transaction information is formed, the transaction for forming the asset transfer is waited until the asset transfer is completed and then broadcast.

S1B, constructing a second multiple signature address, wherein the second multiple signature address is used for signing in each compliance process;
S2B, when polled by the digital asset owner, waits for each compliance process signature. Specifically, a poll is initiated to the compliance flow, for example, for verifier A1, initiate a down-chain flow Tx1{ (a11), (a12),., (A1n) }, where (a11) represents the signature of the waiting compliance flow a11, where (a12) represents the signature of the waiting compliance flow a12, and where (A1n) represents the signature of the waiting compliance flow A1 n.
And S3B, when all the compliance process signatures are obtained, feeding back a verifier signature to the digital asset owner, wherein each compliance process signature is included. After each compliance process department carries out signature respectively, the signature (A1) of the verifier is completed and is fed back to the first multi-signature address created by the initiator.
