Description

Cross-border money transfer method and device based on block chain and electronic equipment

Technical Field

One or more embodiments of the present disclosure relate to the field of blockchain technologies, and in particular, to a blockchain-based cross-border money transfer method and apparatus, and an electronic device.

Background

The cross-border money transfer refers to a business in which a user transfers money to a collection account opened by an overseas bank within a prescribed money transfer limit. Traditional cross-border transfers are implemented primarily based on establishing a transfer channel based on SWIFT (society for worldwide interbank financial telecommunications, global same banking and financial telecommunications association or global inter-bank financial communications association) systems. However, when cross-border money transfer is performed based on the SWIFT channel, since the SWIFT system involves inter-bank transfer and manual operation of a plurality of intermediate banks, the time efficiency and handling costs of the cross-border money transfer are poor, such as: typically, 2-5 days are required to transfer money across the border to account, and each intermediate link involved in the money transfer is charged.

In addition, for consumer users (class-C users) with less amount and frequency of cross-border remittance, the speed remittance company can provide an hour-level to-account cross-border remittance scheme for the consumer users, but the speed remittance scheme depends on a cross-border remittance transaction system of the speed remittance company, and for commercial institutions (class-B institutions) with more amount and frequency of cross-border remittance and own cross-border remittance transaction system, the speed remittance company cannot safely and reliably depend on a centralized cross-border remittance transaction system of the speed remittance company.

Blockchain technology, also known as distributed ledger technology, is an emerging technology that is commonly engaged in "accounting" by several computing devices, together maintaining a complete distributed database. The blockchain technology has the characteristics of decentralization, disclosure transparency, capability of participating in database recording by each computing device and capability of rapidly performing data synchronization among the computing devices, so that the blockchain technology is widely applied in a plurality of fields.

Blockchains are generally divided into three types: public chain (Public Blockchain), private chain (Private Blockchain) and federated chain (Consortium Blockchain). In addition, there may be combinations of the above types, such as private chain+federation chain, federation chain+public chain, and the like.

Among them, the highest degree of decentralization is the public chain. The public chain is represented by bitcoin, ethernet, and participants joining the public chain (also referred to as nodes in the blockchain) can read data records on the chain, participate in transactions, and compete for accounting rights for new blocks, etc. Moreover, each node can freely join or leave the network and perform relevant operations.

The private chain is the opposite, the write rights of the network are controlled by an organization or organization, and the data read rights are specified by the organization. In short, the private chain may be a weakly centralized system with strict restrictions on the nodes and a small number of nodes. This type of blockchain is more suitable for use within a particular organization.

The alliance chain is a block chain between public and private chains, and can realize 'partial decentralization'. Each node in the federation chain typically has an entity organization or organization corresponding thereto; nodes join the network by authorization and form a benefit-related federation, which collectively maintains blockchain operation.

In this specification, the blockchain described above is any type of blockchain that deploys an intelligent contract for cross-border money transfer; the specific type of the blockchain can comprise any one of public chains, private chains and alliance chains.

For example, in practical applications, the blockchain may be a coalition chain.

In this specification, the money transfer initiator may include any business (class B) that is located within the money transfer initiator, has a large amount and frequency for cross-border money transfer, and has a cross-border money transfer transaction system.

For example, the money transfer initiator may be a payment device system or other third party financial institution located within the home and having a cross-border money transfer transaction system.

In this specification, the first receiving and paying mechanism may include a banking mechanism located within the home and supporting cross-border money transfer; wherein the money transfer initiator opens a money transfer account at the first receiving and paying entity.

Continuing with the above example, the first receiving and payment mechanism may specifically be a banking Hangzhou branch of a sponsor located within the home, where the payment facilitator system opens a bank account (money transfer account) for cross-border money transfer.

In the present specification, the second receiving and payment mechanism may include a banking mechanism supporting cross-border money transfer located overseas.

Continuing with the above example, the second receiving and payment mechanism may be, in particular, a located overseas Douglas fir bank branch supporting cross-border money transfer.

In this specification, the money transfer recipient may include any type of money transfer recipient located overseas for receiving a cross-border money transfer of the second receiving and paying institution.

Continuing with the above example, the money transfer recipient may specifically include a class C user or class B institution that has opened a bank account (a recipient account) in the Douglas fir bank U.S. branch. Such as: taking a money transfer recipient as a class B institution as an example, the money transfer recipient may include a third party payment institution or a third party bank that opens a bank account in the douglas bank united states branch, such as: the money transfer recipient may specifically be a national banking U.S. branch that opens a bank account for the U.S. branch at the douglas bank.

In the present specification, the liquidity Provider may include a liquidity Provider (Liquid Provider) having a first account opened in the first receipt/payment mechanism and a second account opened in the second receipt/payment mechanism;

The liquidity provider can provide providers of money transfer, pad payment and currency exchange in the process that the remittance initiator carries out cross-border remittance to the remittance receiver through the first receiving and paying mechanism and the second receiving and paying mechanism.

Continuing with the above example, the liquidity provider may specifically include a branch bank opened by a douglas bank within, for example: the flower banker Hangzhou branches; wherein, the Douglas fir bank Hangzhou branch opens a first account in the tenderer bank Hangzhou branch and a second account in the Douglas fir bank U.S. branch.

The sender, the first receiving and paying mechanism, the mobility provider, the second receiving and paying mechanism, and the receiver may be added to the blockchain network as a node device of the blockchain to collectively maintain a blockchain ledger. Of course, in practical applications, the sender of the money transfer, the first receiving and paying mechanism, the fluidity provider, the second receiving and paying mechanism, and the receiver of the money transfer may access the blockchain by maintaining a connection with the node device on the blockchain, instead of joining the blockchain as the node device of the blockchain, and persist the data generated by itself in the blockchain.

In the present specification, when the money transfer initiator located within the environment initiates a cross-border money transfer to the money transfer recipient located outside the environment, the money transfer initiator may initiate an inquiry request for the cross-border money transfer to the blockchain.

In the present specification, the blockchain receives the cross-border money transfer request initiated by the money transfer initiator; wherein the cross-border money transfer request includes money transfer information;

continuing with the above example, the blockchain receives an enquiry request for a cross-border money transfer initiated by the payment facilitator system; wherein the request for price includes money transfer information.

In this description, further in response to the request for price inquiry, the blockchain invokes the certificate store logic in the intelligent contract to store the money transfer information in the blockchain, so that the liquidity provider performs price inquiry on the money transfer information, and stores a price inquiry result obtained by the price inquiry in the blockchain to be acquired by the money transfer initiator.

Continuing with the example above, in response to an enquiry request from the payment facilitator system for a cross-border money transfer, the blockchain invokes the validation logic in the intelligent contract to store money transfer information A in the blockchain, such that the Douglas bank Hangzhou branch (liquidity provider) enquires money transfer information A.

In one embodiment shown, the money transfer information includes a money transfer account number, a money transfer amount, a first currency, and a collection account number; and in the process of calling the certificate storing logic in the intelligent contract to store the remittance information in the blockchain, the blockchain calls the certificate storing logic in the intelligent contract to store the remittance account number, remittance amount, first currency and collection account number in the blockchain.

Continuing with the above example, the blockchain invokes the forensic logic in the smart contract to store in the blockchain a money transfer account number (e.g., that may include a user name, a card number, etc. of the money transfer account of the money transfer initiator), a money transfer amount, a first currency (e.g., that may include Renminbi), and a collection account number (e.g., that may include a user name, a card number, etc. of the collection account of the money transfer recipient).

In the present specification, after the money transfer information is stored in the blockchain, the liquidity provider obtains the money transfer information and provides an inquiry corresponding to the money transfer information.

Continuing with the example above, the Douglas fir Hangzhou branch (liquidity provider) may query for the on-chain verified remittance information A and save the query result B in the blockchain for acquisition by the payment system.

In one embodiment, the blockchain receives a request for checking, initiated by the liquidity provider, a check result obtained by a check query corresponding to the remittance information;

Wherein, the certificate storage request comprises a price inquiry result obtained by price inquiry corresponding to the remittance information; the price inquiry result includes a money transfer candidate link including a money transfer rate of a first currency relative to a second currency of the liquidity provider support pad and a money transfer commission corresponding to the money transfer amount at the money transfer rate.

Continuing with the above example, the request for depositing a certificate includes a price inquiry result B obtained by inquiring a price inquiry corresponding to the remittance information a; the poll result B may include at least one money transfer candidate link, each including a money transfer rate H of a first currency (e.g., rennet) relative to a second currency (e.g., dollar) of a douglas bank branch (liquidity provider) supporting money transfer and a corresponding money transfer fee C (e.g., a corresponding money transfer fee charged at a preset percentage of the money transfer amount) included in the money transfer information a at the money transfer rate H.

In this specification, further, in response to the request for depositing a certificate, the blockchain invokes a certificate depositing logic in the intelligent contract to store the price inquiry result in the blockchain, so that the money transfer initiator initiates a cross-border money transfer application based on the price inquiry result.

Continuing with the example above, in response to the request for evidence, the blockchain invokes the evidence-storing logic in the intelligent contract to save the price-inquiring result B in the blockchain, so that the payment facilitator system (money transfer initiator) initiates a cross-border money transfer application based on the price-inquiring result B.

In the present specification, after the price inquiry result is verified in the blockchain, the money transfer initiator may obtain the price inquiry result from the blockchain, and initiate a cross-border money transfer application request corresponding to the price inquiry result.

In the specification, the block links a cross-border money transfer application request corresponding to the price inquiry result, which is initiated by a money transfer initiator; the cross-border money transfer application request comprises a confirmation result that the money transfer initiator confirms money transfer according to the price inquiry result.

Continuing with the above example, the blockchain receives a cross-border money transfer application request initiated by the payment system and corresponding to the price inquiry result B; the cross-border remittance application request comprises a confirmation result C that the payment treasure system confirms remittance according to the price inquiry result B.

In this specification, further, the blockchain is configured to call a depositing logic in the smart contract to store the confirmation result in the blockchain in response to the cross-border transfer request, so that the liquidity provider performs a money transfer condition check based on the confirmation result, the price inquiry result, and the money transfer information, and when the money transfer condition check passes and a check result corresponding to the money transfer condition check is confirmed by a money transfer receiver, transfers money of a first currency type corresponding to the money transfer information from the money transfer account to the first account by the first receiving/paying mechanism, calculates money of a second currency type corresponding to the money transfer information based on the price inquiry result and the money transfer information by the second receiving/paying mechanism, and transfers money of the second currency type from the second account to the money transfer account by the second receiving/paying mechanism, thereby completing the cross-border transfer corresponding to the cross-border transfer request.

Continuing with the example above, in response to the cross-border money transfer request, the blockchain invokes the forensic logic in the intelligent contract to save the validation result C in the blockchain to cause the douglas bank branch (the liquidity provider) to perform a money transfer condition check based on the validation result C, the price-enquiring result B, and the money transfer information a, and when the money transfer condition check passes and the check result D corresponding to the money transfer condition check is validated by the rich bank U.S. branch (the money transfer recipient), transfer the rennet money transfer funds (the first currency transfer funds) corresponding to the money transfer information a from the money transfer account to the first account by the douglas bank branch (the first currency transfer funds) to the second account, and calculate the dollar money transfer funds (the second currency transfer funds) corresponding to the rennet money transfer funds (the first currency transfer funds) from the money transfer account to the second currency transfer account by the douglas bank branch (the second currency transfer funds) to the cross-border money transfer request.

In one embodiment shown, the confirmation includes the money transfer initiator selecting a target money transfer link from the money transfer candidate links to perform a money transfer.

Continuing with the above example where the money transfer candidate links include 10 money transfer candidate links, the confirmation result C may include the payment instrument system (money transfer initiator) selecting one or more target money transfer links from the 10 money transfer candidate links to perform the money transfer. In practical applications, the payment device system may perform target money transfer link screening according to a preference or a preset condition selected by a money transfer user, for example: the target remittance link may be ranked according to the rate of remittance and screened based on the ranking result, for example: the target money transfer links may be ranked according to the length of money transfer to account time and screened based on the ranking results.

In this specification, further, in invoking the validation logic in the smart contract to save the validation result in the blockchain, the blockchain may invoke the validation logic in the smart contract to save the target money transfer link in the blockchain.

Continuing with the example above, the blockchain may invoke the validation logic in the smart contract to save the target money transfer link included in the validation result C in the blockchain.

In one embodiment, after the confirmation result is stored in the blockchain, the mobile provider may confirm whether the present money transfer application satisfies a preset money transfer condition based on the confirmation result, the price inquiry result and the money transfer information, and submit a money transfer condition checking result to the blockchain for storing.

Continuing with the above example, the Douglas fir Hangzhou branch (liquidity provider) performs a money transfer condition check based on the confirmation result C, the price inquiry result B, and the money transfer information A, and submits a check result D corresponding to the money transfer condition check to the blockchain for deposit.

The specific contents included in the money transfer condition check are not particularly limited in the present specification. Such as: in practical applications, the checking of the money transfer condition may specifically include checking whether the first account and the second account are normal (not frozen) and whether the balance of account funds of the corresponding currency in the first account and the second account is sufficient, whether the target money transfer link is normal, whether the change of the exchange rate and the exchange fee requires re-checking, and whether the sum and the use of the money transfer funds exceed any one or a combination of regulatory limits according to the confirmation result C, the price checking result B and the money transfer information a.

The money transfer condition checking result comprises a checking result that the mobility provider confirms whether the money transfer application meets the preset money transfer condition or not based on the confirmation result, the price inquiry result and the money transfer information;

the money transfer condition inspection result may specifically include an inspection result of whether the money transfer condition inspection is passed or not passed.

In the present specification, further, the blockchain receives a certificate-preserving request initiated by the liquidity provider to preserve the money transfer condition inspection result; and in response to the request for depositing the money transfer information, invoking depositing logic in the intelligent contract to store the money transfer condition checking result in the blockchain, so that the money transfer receiver confirms the money transfer information based on the money transfer condition checking result, and depositing the confirmed result in the blockchain.

Continuing with the above example, a request for depositing a money transfer condition check result D initiated by a block link receiving a douglas bank Hangzhou branch (liquidity provider); in response to the request for deposit, deposit logic in the intelligent contract is invoked to store the money transfer condition inspection result D in the blockchain, so that the national banking U.S. branch (money transfer receiver) confirms the money transfer information A based on the money transfer condition inspection result D, and a confirmed result E after confirmation is stored in the blockchain.

In one embodiment, when the money transfer condition check result is passed and the money transfer condition check result is confirmed to be passed by the money transfer receiver, the blockchain receives a request for storing a check initiated by the first receiving and paying mechanism to store the frozen information for freezing money transfer funds of the first currency corresponding to the money transfer information; wherein the freeze information is used to indicate a first amount of money transfer funds of a first currency deducted from the money transfer account.

Continuing with the above example, when the money transfer condition inspection result E is a money transfer condition inspection pass and the money transfer condition inspection result E is confirmed to pass by the united states branch of the foreign bank (money transfer receiver), the block link receives a request for depositing the frozen information F, which is initiated by the hangzhou branch of the remitter bank (first receiving and paying institution) and which freezes the money of the rendition currency (money transfer of the first currency) corresponding to the money transfer information a; wherein the freeze information is used to indicate a first amount of RMB (money transfer funds of a first currency) deducted from a money transfer account of the payment system.

In the present specification, further, in response to the certification request, the blockchain invokes certification logic in the smart contract to store the frozen information in the blockchain, so that the money transfer initiator and the liquidity provider check the frozen information and the money transfer information, and certify the checked result in the blockchain.

Continuing with the example above, in response to the certification request, the blockchain invokes the certification logic in the smart contract described above to save the frozen information F in the blockchain to cause the payment facilitator system (money transfer initiator) and the douglas bank Hangzhou branch (liquidity provider) to verify based on the frozen information F and the money transfer information a, respectively, and to certify the verification results G1, G2 after the respective verifications in the blockchain. For example, in practical applications, the payment device system (money transfer initiator) and the douglas bank Hangzhou branch (liquidity provider) can check whether the first amount in the frozen information F is consistent with the money transfer amount in the money transfer information A, so that the risk that the first receiving and paying mechanism or the corresponding block chain link point is wrongly used, or the amount of frozen funds caused by the first receiving and paying mechanism when the first receiving and paying mechanism is attacked by hackers or viruses is tampered with can be avoided.

In practical applications, the check result may specifically include a result that the remittance initiator and the liquidity provider check the frozen information and pass or fail.

In one embodiment, when the first collection/payment mechanism verifies the verification result, the blockchain receives a verification request initiated by the first collection/payment mechanism to verify the remittance information corresponding to the frozen information; wherein the deposit information indicates a second amount of money transfer funds of the first currency to be deposited into the first account.

Continuing with the above example, when the check result G1 and the check result G2 are verified by the state branch of the banking host (first receiving and paying mechanism), the block link receives a certificate storing request for storing the imported information H corresponding to the frozen information F initiated by the state branch of the banking host (first receiving and paying mechanism); wherein the remittance information H indicates a second amount of the rendition's banknote (money remittance of the first currency) remitted into the first account.

In this specification, further, in response to the certification request, certification logic in the smart contract is invoked to save the incoming information in the blockchain so that the money transfer initiator and the liquidity provider verify whether the first amount and the second amount are consistent and certify the verification result in the blockchain.

Continuing with the example above, in response to the certification request, certification logic in the smart contract is invoked to save the aggregated information H in the blockchain to cause the payment facilitator system (money transfer initiator) and the douglas bank Hangzhou branch (liquidity provider) to verify that the first and second amounts are consistent and to certify the verification result J in the blockchain. The risk of maliciously tampering the amount of the funds imported by the first receiving and paying mechanism or the corresponding block chain link point thereof when the first receiving and paying mechanism is hacked or invaded by viruses can be avoided.

In practical applications, the verification result may specifically include a result that the verification passes or fails.

In one embodiment, the blockchain receives a request for depositing the payment information initiated by the first receiving and payment mechanism when the verification result is that the first receiving and payment mechanism passes and the first currency money transfer funds corresponding to the payment information have been transferred from the payment account to the first account; wherein the deduction information is used for indicating that money transfer funds of the first currency corresponding to the money transfer information have been transferred from the money transfer account to the first account.

Continuing with the above example, when the verification result J is passed and the first currency money transfer funds corresponding to the money transfer information H have been transferred from the money transfer account to the first account by the first receiving and payment mechanism, the block links the request for depositing the deduction information K initiated by the first receiving and payment mechanism; wherein the deduction information K is used to indicate that money transfer funds of the first currency corresponding to the money transfer information H have been transferred from the money transfer account to the first account.

In this specification, further, in response to the certification request, certification logic in the smart contract is invoked to store the deduction information in the blockchain to enable the second receiving and payment institution and the remittance receiver to obtain the deduction information.

Continuing with the example above, in response to the certification request, certification logic in the smart contract is invoked to save the deduction information K in the blockchain for retrieval by the douglas bank U.S. branch (second payor) and the national bank U.S. branch (sender).

In one embodiment, when the second receiving and paying mechanism calculates a third amount of money transfer funds of the second currency corresponding to the money transfer funds of the first currency based on the price inquiry result and the money transfer information and verifies the third amount based on the fee deduction information, the blockchain receives a certificate storing request initiated by the second receiving and paying mechanism for storing the third amount; in response to the deposit request, deposit logic in the smart contract is invoked to store a third amount in the blockchain for retrieval and validation by the money transfer recipient and the liquidity provider.

Continuing with the above example, calculating a third amount of dollar money transfer funds (second currency money transfer funds) corresponding to the Renminbi money transfer funds (first currency money transfer funds) based on the price-inquiring result B and the money transfer information A at the Douglas fir U.S. branch (second receiving and payment institution), and checking the third amount based on the fee deduction information K (for example, checking whether the product of the money transfer funds related to the fee deduction information K and the exchange rate related to the price-inquiring result B is consistent with the third amount or not, and if so, depositing the third amount), and blocking a request for depositing the third amount initiated by the Douglas fir U.S. branch (second receiving and payment institution); in response to the deposit request, deposit logic in the smart contract is invoked to store a third amount in the blockchain for retrieval and validation by the national banking U.S. branch (money transfer recipient) and the douglas bank Hangzhou branch (liquidity provider).

In one embodiment, when the money transfer recipient and the liquidity provider confirm the third amount and the second receiving and delivering mechanism pre-transfers money of the second currency from the second account to the receiving account, the blockchain receives a request for depositing a fourth amount of money of the second currency pre-transferred to the receiving account initiated by the money transfer recipient, and in response to the request for depositing, the depositing logic in the smart contract is called to store the fourth amount in the blockchain so that the second receiving and delivering mechanism and the liquidity provider verify whether the fourth amount and the third amount are identical, and the verification result is deposited in the blockchain.

Continuing with the above example, when the third amount is confirmed to pass by the national bank U.S. branch (money transfer recipient) and the douglas bank Hangzhou branch (liquidity provider) and the douglas bank U.S. branch (second money transfer funds) is pre-transferred from the second account to the collection account, the block links a request for a deposit of a fourth amount of dollar transfer funds (second money transfer funds) pre-transferred to the collection account initiated by the national bank U.S. branch (money transfer recipient) and the douglas bank U.S. branch (liquidity provider), in response to the request for a deposit of the fourth amount is saved in the block chain by invoking deposit logic in the smart contract to verify that the fourth and third amounts are in agreement by the douglas bank U.S. branch (second money transfer institution) and the douglas bank Hangzhou branch (liquidity provider), and the verification result L is deposited in the block chain.

In one embodiment, when the verification result is that the second money transfer funds of the second currency of the fourth amount are actually transferred to the collection account by the second receiving and paying mechanism, the blockchain receives a certification request initiated by the second receiving and paying mechanism to certify the actually transferred information; the actual transfer information is used for indicating that money transfer funds of the second currency corresponding to the money transfer information are actually transferred to the collection account.

Continuing with the example above, when the verification result L is that the verification passes and the fourth amount of dollar money transfer funds (money transfer funds of the second currency) is actually transferred to the collection account by the douglas bank united states branch (second collection and payment mechanism), the block links the certification request initiated by the douglas bank united states branch (second collection and payment mechanism) to certify the actual transfer information M; wherein the actual transfer information M is used to indicate that the money transfer funds of the second currency corresponding to the fourth amount of money transfer information a have been actually transferred to the collection account.

In this specification, further, in response to the certification request, certification logic in the smart contract is called to store the actual transfer information in the blockchain, so that the liquidity provider and the remittance receiver acquire and confirm the actual transfer information.

Continuing with the example above, in response to the certification request, certification logic in the smart contract is invoked to save the actual transfer information M in the blockchain to cause the douglas bank Hangzhou branch (liquidity provider) and the national banking U.S. branch (remittance receiver) to acquire and confirm

In one embodiment, the blockchain receives a request for depositing the cross-border money transfer to the account receipt information initiated by the sender when the actual transfer information is confirmed to be passed by the liquidity provider and the sender; in response to the deposit request, invoking deposit logic in the smart contract to store the cross-border transfer to account receipt information in the blockchain to cause the liquidity provider, the second receipt and payment mechanism, the first receipt and payment mechanism, and the transfer initiator to acquire.

Continuing with the above example, when the actual transfer information M is confirmed to pass by the douglas bank Hangzhou branch (liquidity provider) and the national bank U.S. branch (remittance receiver), the block links to receive a deposit request initiated by the national bank U.S. branch (remittance receiver) to deposit the cross-border remittance to the account receipt information N; in response to the deposit request, deposit logic in the smart contract is invoked to store cross-border remittance to account receipt information N in the blockchain to cause the douglas bank branches (liquidity provider), douglas bank branches (second payor institution), the tenderer bank branches (first payor institution), and the payment instrument system (remittance initiator) to be acquired, such that each participant involved in the cross-border remittance can quickly determine that the cross-border remittance is completed.

In the process of calling the intelligent contract to carry out the cross-border money transfer in the above embodiments, when each party of the cross-border money transfer (money transfer initiator, mobility provider, first receiving and paying mechanism, second receiving and paying mechanism, money transfer receiver) confirms and verifies each information (such as money transfer information and information related to the money transfer information) of the cross-border money transfer transaction, the confirmation party of each information can be checked in addition to the specific content of each information, and the confirmation party of each information is completely consistent with each party set when the intelligent contract is initially created; in addition, it may be further detected in real time whether the accounts (remittance account, first account, second account, collection account) respectively corresponding to the parties of the cross-border remittance are frozen, for example: in practical application, in the cross-border money transfer process, any one or more of a money transfer account of a money transfer initiator, a first account of a mobility provider, a second account of a mobility provider, and a collection account of a money transfer receiver may be frozen due to failure of internal verification of a wind-controlled back money laundering system of each participant of the cross-border money transfer or verification of a money transfer wind-controlled back money laundering system of a national regulatory agency, at which time, the various confirmation results and verification results involved in the above embodiments may be set as failed by the corresponding each participant; otherwise, the pass is set by the respective participants.
