Detailed Description
The present application is described in further detail in with reference to the drawings and the examples, it being understood that the specific examples are set forth herein for the purpose of illustration only and are not intended to be limiting.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
Fig. 1 is a flowchart of a risk control method for managing digital assets according to an embodiment of the present invention .
As shown in fig. 1, in this embodiment, the present invention provides methods for controlling digital asset hosting risk for a user end, where a blockchain is configured with a contract for managing the money drawing amount of a hosted account, and a device running the user end is configured with a plurality of third-party identity authentication distributed applications (third-party identity authentication DAPP) specified by a blockchain, where the method includes:
s12, in response to the current user' S quota operation, generating quota transactions and sending the quota transactions to the nodes of the block chain for broadcasting, packaging and executing through the contract, and recording the quota transactions on the block chain;
s14, accessing the third-party identity authentication distributed application for identity authentication, generating an identity authentication transaction and sending the identity authentication transaction to a node of a block chain for broadcasting, packaging and executing through a contract after the identity authentication of the third-party identity authentication distributed application is completed, generating a money-withdrawing result according to the money-withdrawing transaction and the identity authentication transaction to update the money-withdrawing amount of the current user and recording the money-withdrawing amount on the block chain;
s16: and acquiring the money drawing amount of the current user.
For example, a user A hosts 10000 XXA coins, and a hosting service end transfers corresponding 10000 YYY _ XXA tokens to a hosting account of the user A on an th blockchain (wherein, the hosting principle can refer to CN201811151114.0 patent), in the embodiment, a th contract for managing the money lifting amount of the hosting account is configured on a th blockchain, three third party identity authentications DAPP specified by th blockchain are configured in a device of a running user end of each user, SFRZ1, SFRZ2 and SFRZ3, and the money lifting amount is initially configured to be 500 YYYY _ XXA tokens/day.
Taking the example that the user A has extracted 50XXA coins on the same day, when the user A needs to extract 2000 XXA coins, the user side of the user A acquires the residual coin lifting amount of 450XXA coins on the same day by acquiring the data of the th block chain and displays the coin lifting amount in the display interface, and after the user A acquires the information, the user side inputs the money lifting operation of lifting the coin lifting amount of the same day to 2500XXA coins.
In step S12, in response to the above mentioned denomination-raising operation by the user a, the user side of the user a generates a request to raise the current day denomination degree to the denomination trade tx1 of the 2500XXA currency and sends it to the node of the th blockchain.
After the node of the block chain receives tx1, broadcasts tx1, packs tx1 into blocks, executes tx1 by the contract of , records tx1 on the block chain , and waits for receiving a corresponding authentication transaction to process a quota request of tx 1.
In step S14, the user side of the user a accesses (may randomly select, select a default item, or be selected by the user) third-party authentication DAPP, for example, accesses SFRZ1 to complete authentication, wherein in this embodiment, the user side of the user a should provide a hash value hash of tx1 (tx1) when invoking the interface to access SFRZ1 for generating an authentication transaction, and in further embodiments, other information for searching for tx1, for example, may be configured to be an amount-providing request number assigned to tx1, or other different information that may be understood by those skilled in the art.
After the user A completes identity authentication, the SFRZ1 generates an identity authentication transaction tx2 according to an identity authentication result and hash (tx1) and sends the identity authentication transaction tx2 to a node of a block chain .
After receiving tx2, broadcasts tx2, packs tx2 into blocks, executes tx2 according to the above contract, finds tx1 according to hash (tx1), and confirms whether the identity authentication of the user A is successful according to the identity authentication result in tx 2:
if not, the quota request of tx1 fails, and the quota degree of the current day of the escrow account of the user A is unchanged;
if yes, the quotation request of tx1 is successful, and the quotation of the current date of the managed account of user A is modified to 2500XXA and recorded on the block chain.
In step S16, the user end of the user a obtains the money-drawing amount of the user a on the current day through the data of the block chain, and displays the money-drawing amount on the display interface, so that the user a can perform the money-drawing of the 2000 XXA coins after knowing that the money-drawing amount is successful.
The above embodiment exemplifies the method shown in fig. 1 by using the initial configuration of the denomination as 500 tokens/day, tx1 requests to raise the denomination of the withdrawal on the current day, in further embodiments, the initial configuration of the denomination of the withdrawal in the above method may be also, according to actual needs, the fixed quota in every th cycle (for example, every day, every week or every month, etc.), the proportion of the second fixed quota in every th cycle (which may be initially configured by and allowed to be modified by the user, or may be configured by the user himself when creating the escrow account), or other different configurations that may be understood by those skilled in the art, and tx1 may request to raise the withdrawal on multiple days or days, etc., all of which may achieve the same technical effect.
In addition, it should be noted that the third-party identity authentication DAPP may be decentralized managed by a decentralized manager of the blockchain (for example, management committee/super node/all users, depending on which types of blockchains the blockchain is specifically configured for), when there is abnormal behavior such as service abnormality or cheating in the third-party identity authentication DAPP, the user side may generate a complaint transaction according to corresponding evidence and send the complaint transaction to the node of the blockchain to trigger the complaint procedure, and regarding the management procedure after triggering the complaint procedure, a person skilled in the art may understand the decentralized management procedure, which is not described herein again.
In the embodiment, the contract for managing the escrow account money lifting amount is configured on the blockchain, and whether the money lifting amount is lifted is judged according to the contract sent by the user end and the identity authentication transaction sent by the third party identity authentication appointed by the blockchain after the user performs identity authentication, so that the escrow account is controlled by the contract configured on the blockchain and the third party identity authentication server manageable by the blockchain, the escrow service and the wind control service are separated, and the decentralized management of the wind control strategy configuration management is realized.
In a preferred embodiment, the contract is further used for judging whether the rate-offer transaction triggers wind control authentication according to a pre-configured wind control strategy when the rate-offer transaction is executed, recording a judgment result on the blockchain, so that a wind control server side obtains the judgment result, performs wind control investigation when the rate-offer transaction triggers the wind control authentication, generates a wind control transaction according to the investigation result and sends the wind control transaction to a node of the th blockchain, and executes the wind control transaction to record the investigation result on the th blockchain;
generating the rate-increasing result according to the rate-increasing transaction and the identity authentication transaction comprises generating the rate-increasing result according to the rate-increasing transaction, the identity authentication transaction and the investigation result.
Specifically, taking as an example a configuration of a pneumatic control policy to identify an abnormal quota request (e.g., multiple quota request in a short time, multiple quota request in a single day, large quota request in a short time, abnormal quota identified based on user characteristics, abnormal quota identified based on business characteristics, etc.), when a quota request of tx1 is identified as an abnormal quota request when a quota transaction tx1 is executed by an contract, a pneumatic control authentication is triggered, and abnormal quota request information is generated and recorded on block chain.
After the wind control server acquires the abnormal quota increasing request information, manual wind control investigation or automatic wind control investigation can be performed according to a preconfigured wind control flow, a wind control transaction tx3 is generated according to the investigation result, and tx3 is sent to the node of the block chain.
After receiving tx3, the th blockchain node broadcasts tx3, packs tx3 into blocks, executes tx3 according to the th contract, and records the investigation result on the th blockchain, so that when tx2 is executed, whether the quota request is successful is judged according to the identity authentication result and the wind control investigation result.
Preferably, to avoid that the client sends tx2 in advance before tx3 succeeds in execution and tx2 cannot succeed in execution, tx2 needs to be retransmitted, th contract may be configured to determine whether tx1 triggers the wind-controlled authentication when tx2 is executed:
if yes, judging whether the th block chain records the corresponding tx 3:
if yes, judging whether the quota request is successful according to tx1, tx2 and tx 3;
if not, recording tx2 on the block chain and waiting for the corresponding tx3 before timeout, and judging whether the block chain has the corresponding tx2 when executing tx3, if yes, judging whether the quota request is successful according to tx1, tx2 and tx 3.
The above embodiment further configures a wind control policy not limited to limit note-lifting in a contract, and a wind control service party performs wind control investigation when triggering wind control authentication, so that further improves a wind control mechanism.
Preferably, in any method, when the money withdrawal transaction before or after the withdrawal is configured as a payment transaction, a deferred payment parameter can be configured in the payment transaction based on a wallet retrieval scheme (see CN201410533888.5 patent), so as to combine the wind control of the escrow account with the on-chain deferred withdrawable payment.
