Example 1:

In registration link, the data record of a digital transaction in assets real name information intelligent contract block is created.The data The real name information of storage user in record.

The real name information may include at least one of: Real Name, perfect instrument information, gender, certification mailbox, registration Cell-phone number, generated block are transferred accounts the information such as address.The identification information that the Real Name can be approved by official, for example, The name that is registered in household register writes on name on identity card or passport etc..

For real name information to be saved by the block forms of broadcasting, obtaining alliance's chain (block chain network) interior supervisory node (should One kind that node can be block chain node being monitored, the monitoring node can be one kind of supervisory node in some cases) ballot is really Recognize by being stored by accounting nodes after verifying.

Real name information is defined as saving using the form of key-value pair in intelligent contract, major key use (E-mail address, The identification informations such as social account), it is worth for the data entity of real name information.

Real name information in intelligent contract is stored on each block chain node of block chain, is referred to by contract address To the contract informations such as the real name information of its user and address of transferring accounts.

Specific transferring step can include:

It initiates transfer request and identifies the addressing for the address that transfer accounts based on the side of being transferred in transfer request

When transaction, after the side of producing selects the side of being transferred to, a transfer request can be initiated (with directly filling in other side E-mail address Location, alternatively, if being unwilling to directly display E-mail address in transaction, by the E-mail address and generation information Mapped, formed mapping relations), then at this time transfer request carry be the code name for having mapping relations with E-mail address Information.

Transfer accounts address generation but generate one by one, for example, an address of transferring accounts is currently generated, if transferring accounts address not yet It receives and transfers accounts, then the address of transferring accounts maintains effectively or within a specified time to maintain effectively always, while shielding other and transferring accounts ground The generation of location, in this way, the side of being transferred to is made only to be corresponding with an address of effectively transferring accounts.Herein effective can are as follows: Ke Yijie Receive the address transferred accounts.Therefore the address if the existing block of user is transferred accounts, a new address will not be created again.Pass through The functional query of real name information intelligent contract goes out the real name information of target user and its address of transferring accounts of carrying.

Block is generated to transfer accounts address, it may include:

According to the private key of the block wallet of target user, counted using elliptic curve encryption algorithm (ECDSA-secp256k1) Calculate public key corresponding to the private key.

The cryptographic Hash of public key is calculated, for example, calculating the Keccak-256 cryptographic Hash of public key；

Take rear 20 bytes that cryptographic Hash is calculated.

It transfers accounts the digital signature of address, comprising:

Using symmetric encipherment algorithm (AES), to transfer accounts, address is signed, and encrypted result is encoded using base64, Key is the E-mail address of user.It is signed simultaneously using same principle to promoter account address.

It is transmitted together with other Transaction Informations by block after digital signature.Block herein is packaged can include: will be counted Word signature and Transaction Information (transfer information corresponding to front) are written in the block of block chain.

Verifying before block packing can include:

The address of transferring accounts for the both sides that transfer accounts is verified, using the E-mail address of target user (side of producing) to address of transferring accounts It is encrypted.

If the ciphertext after encryption is consistent with signature ciphertext, it is verified.Otherwise Fail Transaction, affairs of transferring accounts are returned Rolling.

Transfer result confirmation, it may include:

This link is improving performance, the mode of portion centers can be taken in alliance's chain, each side specifies supervisory node.Example Such as, the both sides that transfer accounts are verified, the E-mail address of target user is used to encrypt as key pair address of transferring accounts；And/or If the ciphertext after encryption is consistent with signature ciphertext, it is verified.Otherwise Fail Transaction, transaction rollback of transferring accounts.

The side of producing is no longer needed in digital asset process of exchange using this exemplary automatic addressing scheme of transferring accounts Complicated block address is remembered, without worrying that mistake is filled in address.For the side of being transferred to, then it is not necessarily to as each side of producing user It goes to generate an address of transferring accounts, equally without the Problem-Error for worrying address, promotes transactions velocity, ensure that the accurate of transaction Property.

The core key point of automatic addressing of transferring accounts is, stores real name information using block chain, usurps real name information not Change；It is digitally signed in block transfer procedure using real name information, guarantee address of transferring accounts is authentic and valid；Block is packaged and hands over Easily confirmation link carries out sign test to digital signature, verifies the authenticity of transaction.

This example is based on all the problems above, and a kind of block of proposition is transferred accounts the solution of automatic addressing.It solves In public chain transaction because during complicated block address circulate between user, it is easy to appear various wrong and generates dispute The problem of, while providing the transparent just trading environment that private chain cannot provide.And trading efficiency is improved, ensure that state Execution of the laws and regulations of the system of real name of family in digital asset process of exchange.

Example 2:

Step 1: saving real name information, specifically can include:

An intelligent contract is created, intelligent contract will generate after being created to be stored in the block chain of block chain generation Contract information.

Construct the data structure of a real name information set (key-value pair, major key be registration email, value is data knot Structure body), which defines including but not limited to properties: address name, the birthday, perfect instrument type, has gender Effect passport NO., perfect instrument photo, registion time, block are transferred accounts, and (a key-value pair set, different types of number provide for address The contract address of production corresponds to different addresses of transferring accounts), certification mailbox, registration phone number.

When registration, real name information, which will store, to be stored within a block by intelligent contract.

Step 2: generating address of transferring accounts can include:

Address Hash (hash) of generation, such as:

" 0x5127f78B7f22405c4248ad08865b553A0d053bBD ", wherein " 0x " is Fixed CP, instruction The address can be Hash Round Robin data partition corresponding to address of walking around.

Step 3: the digital signature for address of transferring accounts, the account book node of block chain network is broadcasted and is stored in after digital signature In.

Step 4: the addressing for address of transferring accounts, specifically can include:

The real name information of user is stored in the memory space of contract address direction in the form of key-value pair.

" 0x254247d6735fa73036ef9e3b3a2bf1a18377a2e2 " is the contract address of certain digital asset.

It may be defined in this way in this real name information intelligent contract, program passes through functional query address:

Map realNameInfo；// real name information

function queryAddrss(string email,address contractAddress){

Return realNameInfo [emial] [contractAddress] } // it is passed to the E-mail address authenticated With contract address.

For example, function queryAddrss is the E-mail address of incoming certification and the letter for exporting contract address Number.In above-mentioned function, " contractAddress " represents the contract address；" email " represents aforementioned electronic email address.

The operation of digital signature can be as follows:

It is signed using symmetric cryptography (AES) mode, such as using the address hash above, key is test@ 163.com.So encrypted result are as follows:

“2y1SFEYvDipKOx4Ybe707R64v5D0U6xhzkwEfu1QrzWA6XIXn9vGgWNjENK0Lm6k”

Step 5: the verifying of digital signature, it may include: address is encrypted in the way of previous step digital signature in plain text After compare.

Example 3:

As shown in figure 8, this example provides a kind of transfer account method based on block chain, comprising:

It transfers accounts beginning:

The target user for selecting transaction, can correspond to the aforementioned selection side of producing mark；

Judge whether to have generated the address of transferring accounts of block chain, if it is not, enter generate block chain transfer accounts address the step of, If so, the address of transferring accounts to both sides is digitally signed；

Block chain miner's node verifies digital signature；

If being proved to be successful, block chain miner handles Transaction Information (corresponding to transfer information above-mentioned) packing；

If authentication failed, terminates this and transfer accounts.In some cases, the method also includes requests to transfer request Side (the i.e. aforementioned side of producing) sends failure prompt of walking around, and failure cause is gone back in the failure prompt of transferring accounts described in some embodiments, with Promote user experience.

Other block chain miner nodes carry out verifying digital signature to address of transferring accounts, if being verified, success of transferring accounts, and note It records in block of transferring accounts.

Example 4:

As shown in figure 9, the block chain network includes the following three types block chain link the present embodiment provides a kind of block chain network Point:

This example, the supervisory node, miner's node and the account book node are relatively independent node；For example, Any two in the supervisory node, miner's node and the account book node are all disposed on different physical equipments, Alternatively, corresponding on the virtual unit of setting cloud platform；So, it can be ensured that the function of each node has enough separating degrees, To reduce the performance requirement to single equipment, to simplify building for block chain network, while single equipment being avoided to add up excessively Load, leads to the problem that the speed of response is slow.

This example, the storage logic and data operation logic of the account book node are separation, are independent from each other.Such as This, by storing the decoupling of logic and data operation logic, account book node can voluntarily layout data be stored, data can be deposited It stores up in off-line device or the network equipment, is not limited to this node, while some long-term unused blocks can also be deleted, with section Save the consumption of storage resource；Alternatively, some data that do not inquire for a long time of compression, can equally save the consumption of storage resource.

In this example, the block chain network can be alliance's block chain network, and the block chain can be alliance's block chain, Alliance's chain that alliance's block chain network generates.Alliance's chain is different from the public chain towards all public and is only oriented in a certain group The privately owned chain in portion；On the one hand alliance's chain realizes the transparence of data supervision towards multiple groups relative to privately owned chain, it is ensured that The safety of data；On the other hand relative to public chain, the supervision of alliance's chain is easier.

It is described to store the block chain independently of the storage logic of the data manipulation logic, including it is following at least it One:

Deletion meets the block data for meeting the first preset condition in the block chain；

The block for meeting the second preset condition in the block chain is stored into predetermined storage equipment, wherein described pre- Surely storage equipment is the off-line device or the network equipment independently of the account book node.

The block data for meeting the first preset condition may include at least one of:

Duration apart from current time has reached the block data of the first preset duration, although when an account book knot removal Partial data, other account book nodes can save complete data；

Delete the block data for the digital asset currently destroyed or recalled.

Pass through the deletion of block data, it is possible to reduce storage resource needed for memory block chain.

In some embodiments, delete block data can using block data as granularity, can also using block as granularity, if with Block is that granularity can simplify deletion.

For example, some blocks are dumped in off-line device or the network equipment, to reduce the account book node itself The storage resource of required offer.

The block for meeting the second preset condition may include at least one of:

Duration apart from current time has reached the block of the second preset duration；Optionally, second preset duration Less than first preset duration；

The block for the digital asset that transfer has currently been destroyed or recalled.

Optionally, which is characterized in that the method also includes:

Receive the block chain query request that client is sent；

Receive the verification result of the identity information of the client of supervisory node broadcast；

If the identity information of the client responds the block chain query request by verifying.

The authentication of the request of block chain query in this example is executed by supervisory node, in this way, the account book section Point can reduce work load, to retain more resource response block chain queries and the generation of block chain and storage.

Block data herein may include the data of aforementioned middle generation of transferring accounts.
