Technical Field

The present application relates to the field of network technologies, and in particular, to a method, an apparatus, a system, a node device, and a storage medium for integrating numerical values.

Background

With the development of network technology, numerical value transfer is involved in more and more scenes. Electronic payment is a value transfer process. The electronic payment refers to that a user sends a value transfer request to certain electronic equipment through a network, and the electronic equipment transfers a certain value in an account of the user to other accounts according to information in the value transfer request.

In a scenario of processing a value transfer process by using a blockchain technique, a user generally sends a value transfer request to a blockchain system through a network, the blockchain system generates a block based on the value transfer request, identifies the block, and when the identification passes, deletes an unconsumed Transaction Output (UTXO) to be transferred from a payment account in an account table, and adds a certain value of UTXO to the payment account in the account table. For example, if user a needs to pay for user B3-tuple and user a does not have a 3-tuple denomination UTXO in its account, the node device in the blockchain system may delete the 5-tuple denomination UTXO in user a's account, add a 3-tuple denomination UTXO in user B's account, and add a new 2-tuple denomination UTXO in user a's account.

However, as the number of value transfer times increases, some UTXOs with small or irregular denominations may not be easily spent, which may result in more and more UTXOs in the account and larger occupied storage space, so that the load of the node device in the block chain becomes larger and larger, and therefore, a method for integrating the values to reduce the number of the UTXOs in the account is needed to reduce the storage space occupied by the UTXOs in the account.

Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

Fig. 1 is an implementation environment of a numerical integration method provided in an embodiment of the present application, and referring to fig. 1, the implementation environment may include a terminal 101, a server 102, and a plurality of servers 103, where two of the terminal 101, the server 102, and the plurality of servers 103 may be connected through a network to implement data interaction, and the plurality of servers 103 are all node devices in a blockchain system, where a network formed by the plurality of servers 103 may be a Peer-to-Peer (P2P) network, and node devices in the P2P network are all peers, that is, have the same status.

The terminal 101 refers to a user equipment, the server 102 is an external device of the blockchain system, the terminal 101 may directly perform data interaction with the blockchain system to obtain a numerical integration service provided by the blockchain system, and may also obtain the numerical integration service from the blockchain system through the server 102, which is not limited in this embodiment of the present application.

In the embodiment of the present application, each server (node device) in the blockchain system has its own blockchain, where the blockchain includes a plurality of blocks, and each block may record therein different content of the value transfer request or content of the value integration request, and of course, may also record other content, which is not limited in this embodiment of the present application.

The following is a description of the terms referred to in this application:

intelligent contract: the contract program automatically executed according to specific conditions is an important way for a user to interact with the block chain and realize business logic by utilizing the block chain.

The numerical integration method may be applied to an electronic device, which may be the terminal 101, the server 102, or any one of the servers 103, and the following description will be given by taking an example in which the terminal 101 or the server 102 and the server 103 interact with each other in the embodiment shown in fig. 2. Fig. 2 is a flowchart of a numerical integration method provided in an embodiment of the present application, and referring to fig. 2, the method may include the following steps:

201. the electronic device obtains UTXO information for the target account from an account table of the blockchain system.

In the embodiment of the application, the electronic device can detect the UTXO information in the target account and perform numerical integration on the UTXO when the UTXO meets the numerical integration condition, so that the number of the UTXO in the target account is reduced, and the storage space occupied by the UTXO in the target account is reduced.

Wherein the target account may be any user account. The node device of the block chain system generally stores the account table, and the account table is used for storing UTXO in the account. In the account table, each account usually has its corresponding index information, and the electronic device can obtain UTXO information of a certain account according to the index information. In this embodiment of the present application, the electronic device may obtain UTXO information of the target account from an account table of the blockchain system according to the index information of the target account; wherein, the index information is the account address of the target account; or, the index information is a transaction hash value. Of course, the index information may also be other information that can uniquely identify the target account, which is not limited in this embodiment of the application.

Specifically, the electronic device may send an information acquisition request to the blockchain system, and the blockchain system acquires the UTXO information of the target account according to the index information carried in the information acquisition request and sends the UTXO information to the electronic device, which is of course, the electronic device may also acquire the UTXO information in other manners, for example, the electronic device may access and read an account table stored in any node device in the blockchain system, and locally generate an account table copy according to the read content, so as to acquire the UTXO information of the target account, which is not limited in this embodiment of the present application.

In the embodiment of the present application, the electronic device may be the terminal 101 in fig. 1 or may be the server 102. When the electronic device is a server 102, the relationship between the server 102 and a terminal 101 may be different, wherein the terminal 101 refers to a user device. Specifically, the following three cases may be included:

in one case, the electronic device is the terminal 101 described above.

The terminal may obtain UTXO information of the target account from the account table of the blockchain system, that is, the user equipment may access the account table to obtain UTXO information of a certain account from the account table.

In one possible implementation manner, the terminal may access the node device in the blockchain system through an installed client or through a web portal to acquire the UTXO information of the target account. In a specific possible embodiment, an access interface of the node device may be set in the client or in the web portal, and the terminal may access the account table on the node device through the access interface. In a possible implementation manner, the terminal may further obtain UTXO information of the target account from the account table and provide the UTXO management function of the target account for the user. For example, the terminal may provide the sum of the denomination of the UTXO of the target account for the user according to the obtained UTXO information of the target account, that is, the user may learn the "balance" in a certain account through a "wallet" in the terminal.

In one case, the electronic device is the server 102, and the server 102 stores a unique key of the target account provided by the terminal 101.

The terminal may provide the unique key of the target account to the server, and the server may manage the target account according to the unique key. For example, this case may be an account escrow, in which the terminal escrows the target account to the server, that is, the terminal gives the server the management right of the target account, and the server may perform any operation on the target account through the unique key.

In one case, the electronic device is the server 102, and the key with the target account partial authority provided by the terminal 101 is stored in the server 102.

The terminal can delegate a part of business functions of the target account to the server and the server completes the business functions. The unlocking method may specifically be implemented by using a multiple signature technology, where the multiple signature technology may be an M-N multiple signature technology, where N is the total number of public keys, and M is at least M public keys of the N public keys required for unlocking. For example, a multiple signature technique 1-2 may be adopted, that is, the terminal generates two pairs of keys for the target account, where there are two private keys and two public keys, and unlocking may be performed using one of the public keys, and of course, the public key needs to be a public key corresponding to the private key used for locking. The terminal may provide one pair of keys to the server and may also set an operation right for the key, that is, the key has a partial right of the target account. In a possible implementation manner, the terminal may also generate a plurality of private keys and a public key for the target account, where the public key may be used to unlock information locked by any one of the plurality of private keys.

202. And when the UTXO in the target account is determined to meet the numerical value integration condition according to the UTXO information, the electronic equipment determines a first quantity of UTXOs to be transferred out and a second quantity of UTXOs to be transferred in the target account according to the UTXO information and the numerical value integration rule.

The electronic device may detect whether the UTXO in the target account meets a numerical value integration condition according to the obtained UTXO information, and if so, may perform the following steps related to numerical value integration, and if not, may perform the above steps 201 and 202, and continue the detection. In one possible implementation manner, the electronic device may periodically perform step 201 described above, and perform a step of detecting whether the UTXO in the target account meets the value integration condition.

The condition that the UTXO in the target account meets the value integration condition may include: the number of UTXOs in the target account is greater than a first number threshold; or the number of UTXOs with the denomination less than the denomination threshold in the target account is greater than a second number threshold; or the storage space occupied by the UTXO in the target account is larger than a preset capacity. The first quantity threshold, the second quantity threshold, the denomination threshold, or the preset capacity may be preset by a relevant technician, or may be adjusted by a user according to the actual use requirement of the user. It should be noted that, the above are only examples in which the UTXO in the target accounts meets the value integration condition, and the value integration condition may be preset by a relevant technician according to an actual service function or requirement, or set by a user according to an actual use requirement of the UTXO, and in a possible implementation manner, the value integration conditions of different accounts may also be different, which is not limited in this embodiment of the present application.

For example, a number upper limit may be set in the electronic device, and the electronic device may determine that the number integration is required when it detects that the number of UTXOs in the account is large and the number upper limit has been reached. Alternatively, if the electronic device detects that the number of small-denomination UTXOs is large and the upper limit of the number is reached, it may be determined that numerical integration is required. Or a capacity upper limit may be set in the electronic device, the electronic device may detect a storage space occupied by the UTXO in the account, and if the occupied storage space is large and reaches the capacity upper limit, it may be determined that numerical value integration is required.

When the electronic device determines that the UTXO in the target account meets a value integration condition according to the UTXO information, the electronic device may send a value integration request to the blockchain system, where the value integration request is used to instruct the blockchain system to convert a first number of UTXOs in the target account into a second number of UTXOs, where the second number is smaller than the first number, so that the number of UTXOs in the target account may be reduced, a storage space occupied by the UTXOs in the target account may be reduced, and a load of a node device in the blockchain may be reduced.

Before sending the value integration request, the electronic device may determine specific content of the value integration request, where the specific content may include a first number of UTXOs to be transferred out and a second number of UTXOs to be transferred in the target account. Specifically, the value integration rule adopted by the process of determining the first number of UTXOs and the second number of UTXOs by the electronic device may be preset by a person skilled in the art, which is not specifically limited in the embodiment of the present application, and the following only gives a few examples of the possibilities:

in one possible implementation, the electronic device may treat all UTXOs in the target account as the first number of UTXOs to be transferred out, and determine a sum of the denominations of the second number of UTXOs according to a sum of the denominations of the first number of UTXOs. The electronic device may determine the sum of the denominations of the second number of UTXOs according to the sum of the denominations of the first number of UTXOs by: and the electronic equipment determines the maximum value in each denomination range as the denomination of the second quantity of UTXOs according to the denomination range to which the denomination of each UTXO in the target account belongs, wherein the second quantity is one or is more than one.

For example, the electronic device may integrate all the UTXOs in the target account, and for the denomination of the second number of UTXOs, when the second number is one, the electronic device may integrate all the UTXOs in the target account into one UTXO, and the denomination of the second number of UTXOs is also fixed. When the second number is greater than one, the electronic device may integrate all the UTXOs in the target account into a second number of UTXOs, and a different denomination range may be set in the electronic device, for example, [0,5], (5-10], … …, and if the denominations of the first number of UTXOs are 4, 6, 3, and 2, respectively, 5 and 10 may be used as the second number of UTXOs.

In one possible implementation, the second amount may be determined according to historical transaction information of the target account, for example, a maximum number of transactions performed in parallel in the historical transaction information may be determined as the second amount. Of course, the second number may be a preset number, or the second number may be determined according to the sum of the denomination of the determined second number of UTXOs and the denomination of the first number of UTXOs, which is not limited in this embodiment.

In one possible implementation, the electronic device may treat the UTXOs in the target account having a denomination less than the denomination threshold as the first number of UTXOs and determine a sum of the denominations of the second number of UTXOs based on the sum of the denominations of the first number of UTXOs.

For example, the denominations of the UTXOs included in the target account are 20, 13, 8, 5, 4, 1, and 9, for example, the denomination threshold is 10, the electronic device may use the UTXOs with the denomination less than 10 as the UTXOs to be transferred out, that is, the first number may be 5, the first number of UTXOs may be 8, 5, 4, 1, and 9, and the determination process of the second number of UTXOs is the same as in the foregoing implementation manner, which is not described in detail herein.

In one possible implementation manner, the electronic device may use, according to the historical transaction information of the target account, the UTXOs in the first range of denominations in the target account as the first number of UTXOs, and use the UTXOs in the second range of denominations as the second number of UTXOs, where the first range of denominations is a range of denominations of the UTXOs in the historical transaction information, where the frequency of the UTXOs in the historical transaction information is smaller than the first frequency threshold, and the second range of denominations is a range of denominations of the UTXOs in the historical transaction information, where the frequency of the UTXOs in the historical transaction information is larger than the second frequency threshold.

For example, if it can be determined in the historical transaction information of the target account that the UTXO with the denomination of 20, 50 or 100 is frequently used by the user or the UTXO with the denomination range of [20,100] is frequently used by the user and the UTXO with the denomination range of [0,20] is rarely used by the user, the electronic device may use the UTXO with the denomination range within [0,20] in the current account as the UTXO to be transferred out, use the denomination of the UTXO to be transferred into 20, 50 or 100, or use [20,100] as the denomination range of the UTXO to be transferred into.

In one possible implementation, when determining the first number of UTXOs and the second number of UTXOs, the electronic device may determine the size relationship between the sum of the denominations of the first number of UTXOs and the sum of the denominations of the second number of UTXOs by:

in one case, the first number of UTXOs is the same as the sum of the denominations of the second number of UTXOs.

Generally, when providing a value transfer service for a user, a node device in a blockchain may charge a certain fee, and in the value integration method provided in the embodiment of the present application, in order to reduce a load condition of the node device in the blockchain, the value integration is performed on the UTXO in the account of the user, which may be a maintenance manner for the device in the blockchain system, and possibly the user does not actually have a desire to perform the value integration actively, so that the method may further include: when the value integration is carried out on the target account, the fee of the value integration service is not charged. That is, the sum of the transferred-in and transferred-out UTXO denominations is the same when the target account is subjected to value integration.

Specifically, the utility of the numerical integration service can be improved by realizing intelligent contracts, or specifying that the transferred-in and transferred-out denominations of the numerical integration request are the same when the block chain system is established, without charging fees. Of course, the above process may also be implemented in other manners, for example, all transfer-in addresses of the charges that are charged are rewritten into account addresses of the target accounts, which is not limited in this embodiment of the application.

In one case, the sum of the denominations of the first number of UTXOs is the sum of the denominations of the second number of UTXOs and a preset denomination.

The predetermined denomination is the cost of integration through the blockchain system. For example, a commission is required for transferring value from the blockchain system, and the value integration process is also a value transfer process, and the preset denomination can be transferred into the account of the blockchain system. Then a portion of the first number of UTXOs in the target account may be transferred back to the target account after being integrated, and another portion may be transferred to the account charged for the predetermined denomination. The preset denomination is preset in the block chain system by a relevant technician, and certainly, the preset denomination of the UTXO collected in the value integration process may be set to be smaller than the denomination of the UTXO collected in the value transfer process.

Based on the value integration condition and the value integration rule, the UTXO in the target account is subjected to value integration, so that the number of UTXOs in the target account can be reduced, the load of node equipment is reduced, the integrated UTXO is easier to cost, and convenience is brought to the UTXO use of a user.

203. The electronic device sends a value integration request to the blockchain system.

The electronic device may send a numerical integration request to the blockchain system after determining the content of the numerical integration request. Generally, the electronic device may store an address of any node device in the blockchain system, and the electronic device may obtain the address and send the value integration request to the address.

In a possible implementation manner, the value integration request may carry a key of the target account, and it should be noted that the electronic device may lock the value integration request by using a private key and then send the value integration request to the blockchain system, that is, send the value integration request after signing the value integration request, and the blockchain system may unlock the value integration request by using a corresponding public key.

In the first two cases, the key is the unique key of the target account provided by the user equipment, corresponding to the three cases in step 201. In the last case, the key is a key provided by the user device with partial rights to the target account. If the multiple signature technology is adopted, the terminal entrusts the target account to the server, the terminal can lock the numerical value integration request by using a private key of the terminal, the server can also lock the numerical value integration request by using the private key with partial authority of the target account provided by the terminal, the block chain system can be unlocked by using the public key corresponding to the private key, and the public key adopted by the block chain system for subsequent unlocking and the numerical value integration request are correspondingly stored, so that the numerical value integration task specifically initiated by a user can be known.

The process of locking the numerical value integration request by the private key is also the process of generating the signature information, and the signature information is carried by the numerical value integration request. If the electronic device adopts a mode of managing the target account by a plurality of private keys and one public key, the blockchain system can correspondingly store the signature information carried by the numerical value integration request and the numerical value integration request in the subsequent process, so that the initiator of the numerical value integration request can be known. Of course, in the step 203, the value integration request may further include other contents, for example, rules referred to by the value integration process or transaction initiation time, which is not limited in the embodiment of the present application.

The above step 202 and step 203 are processes of sending a value integration request to the blockchain system when it is determined that the UTXO in the target account meets the value integration condition according to the UTXO information, so that the blockchain system can subsequently provide the value integration service for the electronic device according to the value integration request.

204. When a value integration request is received, the block chain system generates a block based on the value integration request, and identifies the block, wherein the value integration request is triggered by the fact that the UTXO in the target account meets a value integration condition.

In one possible implementation manner, the electronic device may send a value integration request to any node device in the blockchain system, and after receiving the value integration request, the node device may generate a block based on the value integration request, where the block includes content of the value integration request. Of course, the node device may also generate a block based on a plurality of value integration requests or value transfer requests, and broadcast the block to other node devices, so that the blockchain system may recognize the block.

For example, the process of the node device generating the block may be: the last block in the current blockchain is called the first block, that is, the first block is the block with the highest block height in the current blockchain, and the block being generated by the node device is called the second block. The node device may obtain all information of the first block from the block chain, so as to obtain a block header feature value of the first block based on all information of the first block, perform feature value calculation on information of a contract to be stored in the second block and a value integration request, and obtain a block body feature value of the second block, and further, the node device may store the block header feature value of the first block and the block body feature value of the second block (which may further include a version number, a difficulty value, and a time stamp) to a block header of the second block, and store the information of the contract and the value integration request to a block body of the second block, thereby generating the second block. Thus, the first block and the second block are related by the characteristic value of the block head of the first block, and the aim of connecting blocks in series in a block chain can be achieved. Of course, the above is only an example of generating a block, and the embodiment of the present application does not limit the specific generating process of the block.

Wherein, when the blockchain system identifies the block, it may determine whether the information of the block is accurate, and as to the content of the above-mentioned value integration request in the block, any node device in the blockchain system may query, in an account table stored locally, whether each UTXO in the first number of UTXOs exists and is used, and may determine whether the sum of the transferred-in and transferred-out denominations of the value integration request is the same, wherein the UTXOs need to be able to be queried in the account table and are not used, and the sum of the transferred-in and transferred-out denominations of the value integration request is the same, and the value integration request may be valid, and of course, the identity information of the sender of the value integration request may also be verified, and in a possible implementation manner, after each node device verifies the block, the verification result may be broadcast to other node devices, when the verification result of the node device in the blockchain system that is greater than the preset ratio passes, the blockchain system may determine that the block passes the consensus, and certainly, the specific implementation process of the broadcast verification result and the preset ratio may be preset by a related technician or may be adjusted by the related technician. The blockchain system may perform steps 205-206 described below when it determines that the block passes the consensus.

205. When the block passes the consensus, the blockchain system adds the block to the blockchain.

206. The blockchain system converts the first number of UTXOs in the target account to the second number of UTXOs in an account table of the blockchain system.

Step 205 and step 206 are performed by the blockchain system performing value integration when the block passes the consensus, and recording the process of value integration content at this time. Each node device in the blockchain system may add the block to the blockchain as the block passes the consensus. The node device may further update its own account table information, and the node device may delete the first number of UTXOs from the account table and add the second number of UTXOs to the account table, that is, delete the spent UTXOs from the account table and add an unused UTXO to the account table. Therefore, the account table comprises the UTXO in each account, the block adding step in the block chain of each node device in the block chain system is synchronously performed with the UTXO information updating in the account table, and the accuracy of the account information can be ensured. It should be noted that, the blockchain system may first perform step 205 and then perform step 206, may first perform step 206 and then perform step 205, and may also perform step 205 and step 206 at the same time, which is not limited in this embodiment of the present invention.

It should be noted that, for any node device in the blockchain system, when the block passes the consensus, the node device may perform the step 205 and the step 206, so that the information recorded by each node device is consistent, and the accuracy of the account information can be ensured.

In a possible implementation manner, in the latter case in step 202, the sum of the denominations of the first number of UTXOs is the sum of the denominations of the second number of UTXOs and a preset denomination, and the blockchain system may further add the UTXOs with the denominations of the preset denomination in the account table in the account of the blockchain system.

207. The blockchain system sends an integration success message to the electronic device.

The integration success message is used to inform the electronic device that the first number of UTXOs in the target account has been successfully converted to the second number of UTXOs.

208. The electronic equipment receives the integration success message sent by the blockchain system.

When the electronic device receives the integration success message, integration success prompt information can be displayed in the interface so as to prompt the change condition of the UTXO in the user target account.

The steps 204 to 208 are performed by the blockchain system or the electronic device when the blocks are identified, and in one possible implementation, the blocks may not be identified, and when the blocks do not pass the identification, the blockchain system may ignore the value integration request. That is, if the block does not pass the consensus, the blockchain system may not add the block to the blockchain, e.g., the block may be discarded, and of course, the blockchain system does not need to modify the account table.

Accordingly, the blockchain system may also send an integration failure message to the electronic device. The integration failure message is used for informing the electronic device that the UTXO in the target account is not successfully subjected to value integration. So that the electronic device can receive the integration failure message sent by the blockchain system. In one possible implementation manner, the electronic device may also display an integration failure prompt message in the interface when receiving the integration failure message, so as to prompt that the integration process of the UTXO in the user target account fails. The electronic equipment can also display prompt information to prompt a user that numerical value integration operation can be carried out again. Of course, the electronic device may further re-execute the steps 201 to 203 without being triggered by the user, which is not limited in this embodiment.

As described above by taking the example that the value integration request is sent from the electronic device outside the blockchain system to any node device in the blockchain system through the embodiment shown in fig. 2, in a possible implementation manner, any node device in the blockchain system may further generate the value integration request when detecting that the UTXO in the target account meets the value integration condition, so as to obtain the value integration request. This implementation is described in detail below with the embodiment shown in fig. 3. Fig. 3 is a flowchart of a numerical integration method provided in an embodiment of the present application, where in the embodiment of the present application, the numerical integration method is applied to an electronic device, and the electronic device may be any one of the servers 103, that is, any node device in a blockchain system, referring to fig. 3, the method may include the following steps:

301. the node equipment acquires UTXO information of a target account from an account table of the blockchain system.

An account table is stored in each node device in the block chain system, and the node device may obtain UTXO information of the target account from the locally stored account table, where step 301 is similar to step 201 described above, and this is not described in detail in this embodiment of the present application.

In a possible implementation manner, the node device may periodically perform step 301, and detect whether the UTXO in the target account meets the value integration condition based on the acquired UTXO information, and if so, may perform step 302 described below, and if not, may continue to perform the steps of acquiring and detecting.

302. And when the UTXO in the target account is determined to meet the numerical value integration condition according to the UTXO information, the node equipment determines a first quantity of UTXOs to be transferred out and a second quantity of UTXOs to be transferred in the target account according to the UTXO information and the numerical value integration rule.

The specific content of the value integration request may also be determined when the node device determines that the UTXO in the target account needs to perform value integration, and the specific determination process is the same as that in step 202, which is not described herein again.

303. The node device generates a value integration request and generates a block based on the value integration request.

The difference between step 301 to step 303 is that the node device obtains the value integration request, and step 303 is different from step 203, in that the node device may generate the value integration request after determining the specific content of the value integration request, and may also generate a block including the content of the value integration request, so that step 304 described below may be performed to broadcast the block to other node devices.

304. The node device sends the block to other node devices in the blockchain system.

The node device broadcasts the block to other node devices in the blockchain system so that the blockchain system can perform step 305, described below, to identify the block.

305. The node device shares the block with other node devices in the blockchain system.

The steps 303 to 305 are processes of generating a block and commonly identifying the block based on the value integration request, wherein the block generation process is the same as the process of step 204, and the block chain system can commonly identify the content of the value integration request in the block and also commonly identify other contents in the block, which is not described herein. When the block passes the consensus, each node device may perform steps 306 and 307 described below.

306. When the block passes the consensus, the node apparatus adds the block to the blockchain.

307. The node device converts the first number of UTXOs in the target account into the second number of UTXOs in an account table of the blockchain system.

Step 306 and step 307 are the same as step 205 and step 206, and any node device in the blockchain system can execute step 306 and step 307, which is not described herein again. Like step 205 and step 206, the execution order of step 306 and step 307 is not limited in this embodiment of the application.

In one possible implementation, the block may also fail to pass consensus, each node device in the blockchain system may ignore the value integration request, and the node device may discard the block, not add the block to the blockchain, and not modify the account table.

According to the embodiment of the application, when the UTXO in the target account is detected to meet the numerical value integration condition through the block chain system, numerical value integration is directly carried out, the UTXO with a large quantity in the target account is converted into the UTXO with a small quantity, so that the quantity of the UTXO in the target account can be reduced without user operation or operation of equipment outside the block chain system, the storage space occupied by the UTXO in the target account is reduced, and the load of node equipment in the block chain system is reduced.

All the above optional technical solutions may be combined arbitrarily to form optional embodiments of the present application, and are not described herein again.
