The main idea of the current chain transfer technology of the blockchain is to establish a payment Channel, open the payment Channel (Channel) to process a batch of transactions, record and verify real transaction data under the chain by using some encryption algorithm mechanism, and finally send the transaction data into the blockchain to carry out actual transaction settlement and verification when the Channel is closed. Thus, the number of transactions in the blockchain is reduced greatly, and the purposes of reducing transaction fee and accelerating are achieved. The operation steps are as follows:
The first step: an intelligent contract is deployed on the ethernet, and a contract is deployed for a chain of assets.
And a second step of: and establishing a channel.
And a third step of: after the channel is established, all transactions between the two parties can be performed under the chain.
Fourth step: each time a and B sign transfer information in the chain, there is a serial number, e.g. 1 for the first time and 2 for the second time, if the channel is to be ended (if a initiates), a can send the latest, i.e. the largest, information to the smart contract while providing a lock time. If B provides updated information before the locking time expires, the A cheating date gives the locked assets to B for punishing A, and if the opposite party has no objection when the locking time expires, the contract calculates the final balance of the two parties according to the net increment and decrement of the last piece of information and sends the final balance to the two parties, and the principle is that the single-channel transfer of the thunder and lightning network is realized.
The current lightning multichannel transfer is mainly realized by a hash time lock technology, and the scheme is as follows: when Alice wants to transfer to David, but there is no payment channel between them, if Alice has a payment channel before Bob, carol has a payment channel with David. Alice can then borrow the channel between these nodes (Bob, carol) to transfer the asset to David. Before the entire transmission is completed, the transaction on this channel will be locked using the hash time lock until David confirms that payment has been received on the channel and the entire transaction will be unlocked following Alice unlocking Ha Xisuo the key with the decryption request (SecretRequest).
Finally, each sender will send the Balance Proof to the next recipient. The final state is that everyone on the channel will have a prior Balance Proof, e.g. Bob has a Balance Proof signed by Alice, carol has a Balance Proof signed by Bob, which can be used when closing a pass.
The lightning network solves the problem that the single-channel transfer is convenient, but the multi-channel use has a plurality of problems, and the application of the lightning network is also influenced, and the technical problems of the lightning network are as follows:
Firstly, the off-line problem is that: in the process of multi-channel transfer, if nodes in a payment channel are offline, a multi-channel path cannot be smoothly built.
Secondly, the path searching problem: in the multi-channel transfer, it is difficult to achieve a global view for the decentralized network to find a corresponding multi-channel transfer path, and how to select an optimal path to reduce transfer charges is also a current problem, and meanwhile, it is a difficult point of design that each payment channel node in the multi-channel has enough willingness to mortgage an asset and maintain the payment channel network.
In the scene of a alliance chain, the embodiment of the invention designs a simple and effective multichannel transfer scheme which is low in handling expense and free from node disconnection aiming at the scene of multichannel transfer under the chain. Because the number of alliance chain nodes is limited, each node is allocated with a payment channel management role, and the state of being always on is kept as the state of a blockchain node. Aiming at the problem of multi-channel path searching, a payment channel network structure is built into a payment channel network structure, a multi-channel path intelligent contract is designed, and registration and discovery of routes are realized through the path intelligent contract, so that a user can conveniently perform path selection, and in particular:
based on the hardware structure, the embodiment of the transfer method based on the blockchain is provided.
The first embodiment of the block chain-based transfer method of the present invention comprises:
when receiving a transfer request, acquiring a transfer account and a transfer account in the transfer request;
acquiring an initial node of the transfer account connection and a destination node of the transfer account connection;
traversing a node list, and acquiring a first core node connected with the starting node and a second core node connected with the destination node;
Establishing connection among the transfer-out account, the starting node, the first core node, the second core node, the destination node and the transfer-in account, and generating a payment channel transfer path;
And performing transfer operation along the payment channel transfer path.
The transfer method in this embodiment is applied to the transfer device, and before the step of the first embodiment of this embodiment, the transfer device establishes a payment channel network structure in advance (or the transfer device accesses the payment channel network structure established in advance), where the payment channel network structure refers to a network of connection relations of each node in the coalition chain, and during the transfer operation, a payment channel path can be determined according to the payment channel network structure.
Referring to fig. 2, the steps for establishing a payment channel network structure of a transfer device in this embodiment are specifically described, including:
And step S01, when a payment channel network structure establishment request is received, selecting a preset number of nodes from a alliance chain as core nodes, and associating the core nodes with each other to form a main payment channel.
The transfer equipment receives the request for establishing the network structure of the payment channel, selects a preset number (the preset number is set according to the number of nodes in the alliance chain, in this embodiment, the preset number is 3, the network structure of the payment channel can be a triangle networking structure, thus the payment channel path is five hops at most, the consumption of transfer charges is reduced), and the transfer equipment takes the nodes with the preset number as core nodes, and correlates each core node to form a main payment channel.
For example, referring to fig. 3, the transfer device selects three blockchain nodes from the alliance chain as core nodes of the main payment channel, the three blockchain nodes must be initiating nodes of the alliance chain, the initiating nodes of the alliance chain cannot easily exit the blockchain network, the nodes are ensured to be online constantly, transfer delay and transfer risk caused by offline nodes are avoided, then the transfer device sends an initialization method of the on-chain transaction calling path intelligent contract, an array with the length of 3 is used in the initialization method for storing addresses of the three core nodes, and the transfer device correlates the core nodes to form the main payment channel.
Specifically, step S01 includes:
Step a1, when a payment channel network structure establishment request is received, selecting an initiating node from a alliance chain, and acquiring asset information of each initiating node;
And a2, arranging the initiating nodes according to the amount of the mortgage in the asset information, acquiring a preset number of initiating nodes with the front ordering as core nodes, and associating the core nodes with each other to form a main payment channel.
When receiving a payment channel network structure establishment request, the transfer equipment selects an initiating node from a alliance chain and acquires asset information of each initiating node; the transfer equipment arranges the initiating nodes according to the height of the mortgage amount in the asset information, acquires the preset number of initiating nodes which are arranged in front as core nodes, and correlates the core nodes to form a main payment channel.
In this embodiment, the transfer account device selects the initiating node with higher mortgage amount from the alliance chain as the core node, so that the transfer account device can further ensure the transfer security. It will be appreciated that the transfer device may set the core node's mortgage amount to 3 times that of the other ordinary nodes.
Step S02, nodes except the core node in the alliance chain are evenly distributed to the core node to serve as child nodes of the core node, and connection between the core node and the child nodes corresponding to the core node is established to form a secondary payment channel.
The transfer equipment evenly distributes nodes except the core node in the alliance chain to the core node as sub-nodes of the core node, and establishes connection between the core node and the sub-node corresponding to the core node to form a secondary payment channel, namely, the transfer equipment sequentially selects the rest nodes in the alliance chain and the core node to set a payment channel path. The principle of setting the payment channel path between the rest nodes and the core nodes in the alliance chain is as follows: (1) Nodes under the same mechanism are bound under the same core node as much as possible; (2) Ensuring the balance of the number of the binding nodes of the three core nodes as much as possible; (3) selecting a nearby node according to the network condition.
And S03, forming a key value pair by the address information of the core node and the address information of the sub-node corresponding to the core node, storing the key value pair into a node list of the core node, and completing the establishment of a payment channel network structure.
The transfer equipment forms a key value pair by the address information of the core node and the address information of the sub-node corresponding to the core node, the transfer equipment stores the key value pair into a node list of the core node, namely, the transfer equipment presets a path intelligent contract, associates the sub-node with the core node to be bound through a channel setting function of the path intelligent contract, the channel setting function can find the node list of the core node through mapping < address, address [ ], then, the transfer equipment associates the key with the address information of the core node and the address information of the sub-node establishing a payment channel with the core node to form the key value pair, guarantees the key value pair to the node list of the core node, and completes establishment of a payment channel network structure.
In this embodiment, the account transferring device assigns a user role front (a public-private key pair) for managing the payment channel to each node, for example, the channel management user of the node 0 is front0, and the payment channel node is bound with the blockchain node, so that there is no situation that the payment channel node is offline to cause funds loss and channel unavailability, and the payment operation is more flexible and convenient.
Furthermore, in the present embodiment, the payment channel network structure may be updated according to the service scenario, for example, a new node is added, or a node exits, specifically:
When detecting that the node exits the alliance chain, acquiring a node address of the exiting node;
And writing the node address of the exit node into a cancellation channel function, obtaining a core node associated with the exit node and a node list of the core node, and deleting the node address of the exit node in the node list.
That is, when the transfer equipment detects that the node exits the alliance chain, the transfer equipment acquires the node address of the exiting node; the transfer apparatus writes the node address of the exit node into a cancel channel function, which finds a core node associated with the exit node and a node list of the core node through mapping < address, address [ ], and then deletes the node address of the exit node in the node list. In this embodiment, the common node in the payment channel network structure may be flexibly deleted, so that the payment channel network structure is flexible.
Referring to fig. 4, fig. 4 is a flowchart illustrating a first embodiment of a blockchain-based transfer method of the present invention, the blockchain-based transfer method including:
step S10, when a transfer request is received, a transfer-out account and a transfer-in account in the transfer request are acquired.
The transfer equipment receives the transfer request, the triggering mode of the transfer request is not particularly limited, namely, the transfer request can be actively triggered by a user, or can be automatically triggered by the transfer equipment, when the transfer equipment receives the transfer request, the transfer equipment acquires a transfer account and a transfer account in the transfer request, the transfer equipment judges whether the transfer account and the transfer account are directly connected, if the transfer account and the transfer account are directly connected, the transfer equipment directly executes transfer operation, and if the transfer account and the transfer account are not directly connected, the transfer equipment executes transfer operation according to an established payment channel network structure, and particularly:
step S20, obtaining the starting node of the transfer account connection and the destination node of the transfer account connection.
The transfer equipment obtains the starting node of the transfer account connection, namely, a decentralised structure when the transfer equipment allies with a chain, and the transfer equipment can directly determine the starting node of the transfer account connection according to the source of the transfer request, but can not directly obtain the destination node of the transfer account connection, so that the transfer equipment needs to perform query and determination, and specifically comprises:
Step b1, acquiring an initial node connected with the transfer account, and sending a query request containing the identification of the transfer account to a alliance chain;
Step b2, receiving feedback information according to the query request, and taking a node which sends the feedback information in the alliance chain as a destination node connected with the transfer account;
And b3, if feedback information according to the query request is not received, sending the query request to a server, and acquiring the destination node connected with the transfer account fed back by the server.
Namely, the transfer equipment acquires an initial node connected with the transfer account, and the transfer equipment sends a query request containing the identification of the transfer account to the alliance chain; the transfer equipment receives feedback information of nodes in the alliance chain according to the query request, and takes the node which sends the feedback information in the alliance chain as a destination node for account transfer connection.
If the transfer equipment does not receive the feedback information of the query request, namely, the alliance chain does not actively feed back the destination node corresponding to the transfer account, at the moment, the transfer equipment sends the query request to the server, so that the server sends the destination node connected with the transfer account to the transfer equipment according to the query request.
In this embodiment, each node in the payment channel network structure needs to upload its own information to a central server at regular time. Thus, the user can conveniently inquire the information of each node in the payment channel network structure through the transfer equipment, so that the user comprehensively considers the network topology of the whole payment channel network structure, and it can be understood that the server stores non-core data only as reference data and does not respond to the normal transfer of each node in the payment channel network structure.
Step S30, traversing the node list, and obtaining a first core node connected with the starting node and a second core node connected with the destination node.
The transfer equipment traverses a node list of each core node in the payment channel network structure, and acquires a first core node connected with the starting node and a second core node connected with the destination node so that the transfer equipment establishes a payment channel path.
And step S40, establishing connection among the transfer-out account, the starting node, the first core node, the second core node, the destination node and the transfer-in account, and generating a payment channel transfer path.
The transfer equipment establishes connection among the transfer account, the starting node, the first core node, the second core node, the destination node and the transfer account, and generates a payment channel transfer path so that the transfer equipment performs transfer operation along the payment channel transfer path.
And S50, performing transfer operation along the payment channel transfer path.
The transfer device performs a transfer operation by messaging along each node in the transfer path of the payment channel, specifically, alice now wants to transfer n AAA assets to Bob with reference to fig. 3, but Alice and Bob do not establish a corresponding payment channel. If Alice locates at the starting node 3 of the organization and bob locates at the destination node 7 of the organization, alice first invokes the route searching function of the path intelligent contract, that is, the route searching function searches the address information of the starting node 3 and the address information of the destination node 7, the transfer equipment obtains the payment channel path from the starting node 3 to the destination node 7, and the main logic of the route searching function is as follows:
The transfer equipment traverses a payment channel node list of the core nodes according to the input payment channel node address information, finds a first core node 0 establishing a payment channel with the starting node 3 according to the address information of the starting node 3, and similarly finds a second core node 2 establishing the payment channel with the destination node 7 according to the address information of the destination node 7, and returns a payment channel path: alice-originating node 3-first core node 0-second core node 2-destination node 7-Bob.
It can be understood that Alice obtains a payment channel path of Alice-initiating node 03-first core node 0-second core node 2-destination node 7-Bob through the route searching function, then Alice inquires the mortgage balance of each node in the channel through the transfer equipment, evaluates whether the transfer can be successfully performed, and performs the transfer operation after evaluating that the transfer can be successfully performed.
The payment channel network structure in this embodiment is different from the blockchain network networking architecture in that the payment channel network structure in this embodiment is designed as a triangle networking architecture, and is composed of three core nodes (refer to fig. 3, node 0, node 1 and node 2), and other blockchain nodes can select which one of the three main nodes to establish a state channel according to the network condition. The triangle networking structure in this embodiment can realize the shortest path of transfer, and ensure that at most five hops can reach nodes, because the shorter the path is, the less the handling fee is.
In the embodiment, a node list is preset, and a payment channel transfer path is constructed when a transfer request query node list is received to determine the node through which the transfer passes, so that the node in the payment channel transfer path is ensured to be online at all times, the delay condition of the transfer is effectively avoided, the efficiency of multi-channel transfer is improved, and the risk of the transfer is reduced when the node is online at all times; meanwhile, the transfer path of the payment channel formed according to the node list is shortest, so that the procedure cost of transfer operation is reduced.
Further, on the basis of the above-described embodiment of the blockchain-based transfer method of the present invention, a second embodiment of the blockchain-based transfer method of the present invention is proposed.
This embodiment is a refinement of step S50 in the first embodiment of the present invention, and the difference between this embodiment and the above embodiment is that:
Acquiring the transfer amount in the transfer request, acquiring the number of payment channels in the payment channel transfer path, and determining the procedure cost corresponding to the payment channel transfer path;
The transfer amount, the payment channel number and the commission fee are used as transmission information, the signature of the transmission information is sent to the starting node, the transmission information is processed by the starting node and then forwarded to a first core node, the transmission information is processed by the first core node and then forwarded to a second core node, the transmission information is processed by the second core node and then forwarded to a destination node, and the transmission information is processed by the destination node and then forwarded to a transfer account;
And receiving a decryption request fed back by the transfer account, decrypting the transmission message so that the transfer account obtains the transfer amount and completes transfer operation.
The transfer device creates a new transfer message (locked transfer message) according to the transfer request, and the locked TRANSFER MESSAGE change rule is as follows: transferred _current (transferred): invariable, lock=lock (n, hash, expiration), lock is a hash time Lock, n is transfer amount, secret is hash value, expiration is timeout; the transfer equipment sets a locking amount, wherein the locking amount locked_current=locked_current+n+n is step/1000.0, step is the number of remaining channels in a payment channel transfer path, locksroot = merkelroot of a new lock; sequence number nonce for each transfer = nonce+1.
That is, alice signs this transaction (locked TRANSFER MESSAGE) and sends it to the initiating node 3. Note that the lock amount requires on-band fees (fees are forwarded via five lanes, one thousandth of each lane, depending on the path of the payment lane transfer). Similarly, the initiating node 3 assembles and signs the locked TRANSFER MESSAGE (locked transmission message) according to the rule, and then sends the signed signal to the first checking node 0; the first core node 0 assembles and signs the locked TRANSFER MESSAGE according to the rule, and then sends the signed signature to the second core node 2; the second core node 2 assembles and signs the locked TRANSFER MESSAGE according to the rule and then sends the signed signature to the destination node 7; the destination node assembles and signs the locked TRANSFER MESSAGE according to the rules described above and then sends it to Bob.
Bob sends SecretRequest (decryption request) message to Alice after receiving the signature, requesting Ha Xisuo password; after all relay nodes in the confirmation channel finish hash time locking, alice sends a message secret which reveals the secret to Bob. After Bob has obtained this secret, bob sends a message to the destination node 7 in-chain to reveal the secret, informing him that this secret information is known.
The destination node 7 checks whether the secret is the password of the hash time lock, and if the check is successful, sends an unlocking message to Bob, and updates the latest balance proof to Bob. Locks will be removed from the pending lock list and the transferred _count, locked_count and locksroot values updated.
The destination node 7 sends a message to the previous hop second core node 2 revealing the secret, the second core node 2 checks if the secret is a hash time-locked password, and if successful, updates the latest policy proof to send to the destination node 7. The lock will be removed from the pending lock list and the transferred _amount, locked_amount and locksroot values updated; and so on for the first core node 0, the originating node 3, alice.
Eventually Alice updates the latest balance proof to front0 and updates transferred _account (transfer amount), the values of locked_account and locksroot, and the multi-channel transfer is successfully ended. Because the payment channel node is bound with the blockchain node, the payment channel node is always on-line, and the situation that transfer cannot be performed due to the fact that a certain node is suddenly off-line in the transfer process is avoided.
According to the transfer account equipment, multichannel transfer operation is carried out according to the transfer path of the payment channel, and as the payment channel nodes are bound with the blockchain nodes, the payment channel nodes are always online, so that the situation that transfer cannot be carried out due to the fact that a certain node is suddenly offline in the transfer process is effectively avoided.
Further, on the basis of the above-described embodiments of the blockchain-based transfer method of the present invention, a third embodiment of the blockchain-based transfer method of the present invention is proposed.
This embodiment is a step subsequent to step S40 in the first embodiment of the present invention, and differs from the above-described embodiment in that:
acquiring transfer amount in the transfer request, and acquiring mortgage amounts of the starting node, the first core node, the second core node and the destination node in the transfer path of the payment channel;
comparing the transfer amount with each mortgage amount, and judging whether a mortgage amount smaller than the transfer amount exists;
if the mortgage amount smaller than the transfer amount exists, outputting prompt information;
And if the mortgage amount smaller than the transfer amount does not exist, executing the step of executing the transfer operation along the transfer path of the payment channel.
Namely, the transfer equipment acquires the transfer amount in the transfer request, and the transfer equipment acquires the mortgage amounts of an initiating node, a first core node, a second core node and a destination node in a transfer path of a payment channel; that is, each node in the payment channel network structure may automatically upload information such as its own mortgage amount locking amount to the server, and the transfer apparatus inquires the server to obtain the mortgage amount of each node.
The transfer equipment compares the transfer amount with each mortgage amount and judges whether the mortgage amount smaller than the transfer amount exists or not; if the mortgage amount smaller than the transfer amount exists, the transfer equipment judges that the risk of the payment channel path is higher, and the transfer equipment outputs prompt information when the mortgage amount is insufficient; and if the mortgage amount smaller than the transfer amount does not exist, executing the step of executing the transfer operation along the transfer path of the payment channel.
In this embodiment, after the payment channel transfer path is generated, risk assessment is performed according to the mortgage amount of each payment channel in the payment channel transfer path, when the risk of the payment channel transfer path is high, prompt information is output to prompt for increasing the mortgage amount, and when the risk of the payment channel transfer path is low, payment operation is performed to improve the security of the transfer operation.
