Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the method and system for transaction based on block link according to the present invention are further described in detail with reference to the accompanying drawings and embodiments.
Example 1:
as shown in fig. 1, the present embodiment provides a telephone charge transaction method based on block chains, which is applied to a buyer and a seller, where the buyer and the seller are both parties agreed in advance, and the buyer and the seller may be users of the same operator or users of different operators. In this embodiment, taking the buyer as the user to which the first operator belongs and the seller as the user to which the second operator belongs as an example, the block chain-based telephone charge transaction method includes:
In this embodiment, the transaction amount is a telephone charge amount agreed by the buyer and the seller for the transaction. In another embodiment, the intelligent contract further comprises the identity information of the buyer and the seller, and/or the transaction time, wherein the identity information comprises the name, the identification number, the address, the gender and the work unit information. The transaction time is the time at which the buyer and seller signed the smart contract.
Specifically, there are two different ways in which a buyer signs an intelligent contract with a seller through a seller node via a buyer node. One mode is that a buyer node and a seller node respectively receive a buyer part and a seller part of an intelligent contract template issued by a telephone charge transaction equipment node, wherein the buyer part/seller part of the intelligent contract template comprises a telephone number, a transaction amount and transaction time of the buyer/seller to be filled; the buyer uploads the buyer part of the filled intelligent contract template to the telephone charge transaction equipment node through the buyer node, and the seller uploads the seller part of the filled intelligent contract template to the telephone charge transaction equipment node through the seller node; the telephone rate transaction equipment node generates an intelligent contract according to the buyer part and the seller part of the filled intelligent contract template. The other mode is that a buyer uploads an initial contract determined by negotiation to a telephone charge transaction equipment node through a buyer node and a seller node respectively, wherein the initial contract comprises telephone numbers, transaction amount and transaction time of the buyer and the seller, and the telephone charge transaction equipment node generates an intelligent contract according to the initial contract determined by the negotiation of the two parties.
In this embodiment, the blockchain network includes a buyer node, a seller node, and a telephone charge transaction device node, where the telephone charge transaction device node is connected to the buyer node and the seller node respectively. In one form, the telephone transaction instrument node generates an intelligent contract based on the buyer portion and the seller portion of the populated intelligent contract template, the method further comprising: the telephone charge transaction equipment node judges the transaction amount filled by the buyer and the transaction amount filled by the seller, and when the judgment result is that the transaction amount filled by the buyer is less than or equal to the transaction amount filled by the seller, the transaction amount in the generated intelligent contract is the transaction amount value filled by the buyer; and when the judgment result is that the transaction amount filled by the buyer is larger than the transaction amount filled by the seller, the transaction amount in the generated intelligent contract is the transaction amount value filled by the seller. In another mode, the transaction amount in the initial contract is a value determined by the buyer and the seller according to the actual needs and conditions of the two parties. It should be noted that in both modes, the intelligent contract generated by the telephone transaction equipment node finally includes the signature of the buyer and the signature of the seller.
Optionally, before the buyer and the seller jointly sign the smart contract through the buyer node and the seller node, the method further comprises: the seller inquires the remaining telephone charge or the credit line of the seller account from the second operator node through the seller node to determine the maximum telephone charge line capable of trading, wherein the maximum telephone charge line capable of trading is the difference value between the remaining telephone charge and a preset second threshold value, or the maximum telephone charge line capable of trading is the difference value between the credit line and the preset second threshold value.
In this embodiment, the blockchain network further includes a first operator node and a second operator node, where the telephone charge transaction device node is connected to the first operator node and the second operator node, respectively. The seller sends a request for inquiring the remaining telephone charge or the credit line of the seller account to the telephone charge transaction equipment node through the seller node, and the telephone charge transaction equipment node sends the request to the second operator node. The determination of the maximum amount of the telephone charges that can be traded includes two cases, one case is that when the seller is a prepaid subscriber (i.e. when enough telephone charges are charged to the seller's account in advance), the maximum amount of the telephone charges that can be traded is the difference between the remaining telephone charges of the seller's account and a preset second threshold value. The preset second threshold value may be preset by the seller node according to the seller user requirement, or preset by a second operator node to which the seller belongs. For example, if the value of the second threshold is set to 100 yuan, the seller may trade the maximum telephone charge amount obtained by subtracting 100 yuan from the remaining telephone charge amount of the seller's account. In the second case, when the seller is a postpaid subscriber (i.e. a subscriber with a credit limit overdriven), the maximum available credit limit is the difference between the credit limit of the seller's account and the second threshold.
Optionally, before the seller inquires the second operator node about the remaining telephone charge or credit of the seller account through the seller node, the method further comprises: the buyer inquires the arrearage condition of the buyer account from the first operator node through the buyer node to determine whether the telephone charge transaction can be carried out; when the arrearage duration is smaller than a preset first threshold value, determining that the telephone charge transaction can be carried out on the account of the buyer; and when the arrearage duration is greater than or equal to a preset first threshold value, determining that the telephone charge transaction cannot be carried out on the account of the buyer.
In this embodiment, the buyer sends a request for inquiring the arrearage condition of the buyer account to the telephone rate transaction equipment node through the buyer node, and the telephone rate transaction equipment node sends the request to the first operator node. The preset first threshold value can be preset by the first operator node to which the buyer belongs according to the requirement. For example, the value of the first threshold is set to 6 months, and when the arrearage duration of the buyer account is greater than or equal to 6 months, that is, the buyer account arrearage shutdown is greater than or equal to 6 months, it is determined that the buyer account is not available for the telephone charge transaction.
In this embodiment, after the telephone rate transaction device node generates the intelligent contract, the telephone rate transaction device node writes the intelligent contract signed by the buyer and the seller into the block, and broadcasts the intelligent contract in the block chain network, and each node in the block chain network completes verification and storage of the intelligent contract according to the consensus mechanism. The block information comprises a block chain head and a block main body, wherein the block chain head comprises a Mercker root, a previous block hash and a timestamp; the block body includes phone numbers of the buyer and the seller, transaction amount, and transaction time.
And 103, deducting the telephone charge with the same amount as the transaction amount from the seller account by a second operator node corresponding to a second operator to which the seller account belongs according to the intelligent contract, and charging the telephone charge with the same amount as the transaction amount into the buyer account by a first operator node corresponding to a first operator to which the buyer account belongs according to the intelligent contract, wherein the first operator and the second operator are the same operator or different operators.
In this embodiment, if the buyer and the seller are users of different operators, because each node in the blockchain network stores an intelligent contract signed by the buyer and the seller together, the second operator node to which the account of the seller belongs deducts a telephone fee equal to the transaction amount from the account of the seller according to the intelligent contract, and the first operator node to which the account of the buyer belongs charges the account of the buyer with the telephone fee equal to the transaction amount according to the intelligent contract. It should be noted that after the telephone fee transaction, the second operator and the first operator perform settlement regularly according to the transaction (for example, daily settlement), and the settlement between different operators may adopt the prior art, and thus, the details are not described herein. If the buyer and the seller are users of the same operator, the operator node deducts the telephone charge equal to the transaction amount from the seller account according to the intelligent contract, and then charges the telephone charge equal to the transaction amount into the buyer account. It should be noted that, in the case where the buyer and the seller are subscribers of the same carrier, the settlement between carriers is not involved after the telephone charge transaction. The telephone charge transaction method based on the block chain can realize telephone charge transaction between accounts of different operators or the same operator, enables the telephone charge transaction between the accounts to be rapid and convenient, improves the service quality of telecommunication operators and can also improve the consumption perception of users. And the method adopts the block chain technology, thereby forming the transaction record which can not be tampered, so as to be convenient for inquiring and confirming after the transaction.
Specifically, the second operator node corresponding to the second operator to which the seller account belongs deducts a telephone charge equal to the transaction amount from the seller account according to the intelligent contract, and the first operator node corresponding to the first operator to which the buyer account belongs charges a telephone charge equal to the transaction amount in the buyer account according to the intelligent contract, including two different modes. One way is as follows: the first operator node includes a first operator charging system and the second operator node includes a second operator charging system. The charging systems of different operators are mutually independent, the telephone charge transaction equipment node is respectively connected with the charging system of the first operator and the charging system of the second operator, and because each node in the block chain network stores an intelligent contract, the charging system of the second operator deducts telephone charge with the same amount as the transaction amount from the seller account according to the intelligent contract, and the charging system of the first operator node charges telephone charge with the same amount as the transaction amount from the buyer account according to the intelligent contract, thereby realizing the telephone charge transaction between the accounts. If the buyer and the seller are the users of the same operator, the charging system of the operator node correspondingly carries out fee deduction and recharging operations. In this embodiment, the first operator charging system and the second operator charging system may implement corresponding fee deduction or recharging operations according to the contents of the intelligent contract broadcasted in the blockchain network, and the telephone fee transaction between the accounts may be implemented only by modifying the charging system of each operator.
The other mode is as follows: the first operator node further comprises a first operator business system and the second operator node further comprises a second operator business system. The business systems of different operators are mutually independent, the telephone charge transaction equipment node is respectively connected with the first operator business system and the second operator business system, the first operator business system is connected with the first operator charging system, and the second operator business system is connected with the second operator charging system. The telephone charge transaction equipment node simultaneously sends the telephone numbers, transaction amounts and transaction time of buyers and sellers in the intelligent contract to a business system of a first operator node and a business system of a second operator node to respectively form a first business record and a second business record, the business system of the second operator node sends a fee deduction instruction to a charging system of the second operator node according to the second business record so that the charging system of the second operator node deducts telephone charges with the same amount as the transaction amounts from accounts of the sellers, and the business system of the first operator node sends a recharging instruction to the charging system of the first operator node according to the first business record so that the charging system of the first operator node charges telephone charges with the same amount as the transaction amounts in accounts of the buyers. Thereby effecting a transaction for a fee between the accounts. If the buyer and the seller are users of the same operator, the business system of the operator node sends a deduction instruction and a recharging instruction to the charging system of the operator node according to the corresponding business records, so that the charging system of the operator node carries out deduction and recharging operations. The charging system and the business system of the first operator node and the charging system and the business system of the second operator node in the embodiment do not need to be modified, and can realize the telephone charge transaction between accounts of different operators or the same operator, so that the cost is low and the realization is easy.
In the block chain-based telephone charge transaction method provided by this embodiment, the second operator node to which the seller account belongs deducts a telephone charge equal to the transaction amount in the intelligent contract from the seller account according to the intelligent contract signed by the buyer and the seller in the block chain, and the first operator node to which the buyer account belongs charges a telephone charge equal to the transaction amount in the buyer account according to the intelligent contract signed by the buyer and the seller in the block chain, so that telephone charge transaction between accounts is realized quickly and conveniently, the requirement of giving the telephone charge or paying the telephone charge by the user is met, and the user perception is improved. In addition, the intelligent contracts signed by the buyer and the seller are stored by adopting the block chain technology, so that a transaction record which cannot be tampered can be formed for inquiring after transaction. If the telephone charge transaction between accounts is realized by adopting the mode that the telephone charge transaction equipment node is connected with the charging system of the operator node, the charging system of the operator needs to be modified. If the telephone charge transaction between the accounts is realized by adopting the mode that the telephone charge transaction equipment node is connected with the business system of the operator node, the charging system and the business system of each operator do not need to be modified, the cost is lower, and the realization is easy.
