Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention provides a naming method of resources, wherein the resources can be files, drawings and other resources.
Referring to fig. 1, a naming method applied to resources on a blockchain cluster may include:
s11, receiving a first transaction message sent by the electronic equipment;
wherein the first transaction message is an ODIN message. The first transaction message comprises a source address, a destination address and transaction content after signature operation. The electronic device may be a personal computer PC, a mobile phone, a tablet, etc.
Specifically, the source address is an address of a user who sends the first transaction message through the electronic device. The destination address corresponds to the target individual pointed to by the first transaction message, and may be null when the specific message definition does not require the target individual to be designated. When the destination address is not empty, it indicates that the ownership of the transaction is the user corresponding to the destination address, and when the destination address is empty, it indicates that the ownership of the transaction is still the user sending the first transaction message. The transaction includes, but is not limited to, trading, named transfer, and the like.
The transaction content after signature operation comprises a plurality of 1-of-N multi-signature output block destination address public keys, and a plurality of 1-of-N multi-signature output block destination address public keys, which are defined and encoded according to an ODIN data packet format, and are specifically defined as follows:
in the first 1-of-N multiple signature output, the first public key is fixed to the user sending the first transaction message, the second public key is fixed to the ODIN feature public key (33 bytes public key, 16 system HEX string, such as "0320a0de360cc2ae8672db7d557086a4e7c8eca062c0a5a4ba9922dee0a pref 3e12", corresponding to the address 1PPkPubRnK2ry9PPVW7HJiukqbSnWzXkbi), optionally, the third public key is encoded for the specific first transaction message content (format: the first byte takes the value of 3, the second byte is the subsequent valid data length, the 3 rd byte starts to extract 31 bytes in order from the first transaction message content, the total 33 bytes corresponds to a block-compressed public key (if less than 33 bytes are automatically appended to the tail to fill up the ASCII space character to 33 bytes);
in an optional second and further 1-of-N multiple signature outputs, a first public key is fixed for the user sending the first transaction message and a second public key is initially encoded for the specific first transaction message content.
It should be noted that the value range of N is 3 to 16, and the value is 3 according to the current block protocol standard. Each of the 1-of-N multiple signature outputs defined above is illustrated with N being 3. When N is 4, there will be four public keys in the first 1-of-N multiple signature output, and the fourth public key is the 32 th to 63 th bytes extracted from the first transaction message content in sequence. When N is other numerical value, and so on.
In addition, for the ODIN data block which can not be accommodated by 1-of-N multiple signature output, it is only necessary to expand and store into 2 nd, 3 rd and so on multiple signature output records, if it does not exceed 75 bytes, it can select to store into the following OP _ RETURN remark message. Wherein an OP _ RETURN remark message (providing no more than 75 bytes of additional storage space when a standard multi-transaction data block cannot accommodate an excess length of ODIN packets).
It should be noted that:
(1) there is a certain amount of block balance in the source address (more than 0.001 bit of the currency BTC is recommended for generating valid transaction entries to be sent from the source address to the destination address to embed the ODIN packet, where, due to the characteristics of block 1-of-N multi-signature transactions, these block amounts will not be actually paid out and will be recycled in the next ODIN message).
(2) The message cost flat fee (0.0001 BTC by default) in blocks will be paid to the block network miners who include this block of transaction data.
(3) A block change address (same as the source address, used for recycling the excess amount of the block amount of the input transaction after generating a plurality of transaction entries meeting the embedded ODIN data packet to the account of the message sender according to the block transaction protocol).
A number of 1-of-N multiple signature output block destination address public keys are key in the whole first transaction message, ODIN data blocks are embedded into multiple signature output data blocks of the block transaction and are 1-of-N output, and the first public key of each data block is fixedly the user who sends the first transaction message, so that the output currency value can be redeemed for recycling. The detailed description of the block multiple signature transaction may refer to the block protocol specification.
In addition, the format of each ODIN information data block is defined as follows in byte order:
1 st byte, message type, 1 byte.
The 2 nd byte to the end of the message are different message data distinguished by message type.
S12, when the first transaction message is legal, acquiring a plurality of second transaction messages sent by other electronic equipment in the same time period with the first transaction message;
specifically, when the first transaction message is received, whether the first transaction message is legal or not is verified, and the process of verifying whether the first transaction message is legal or not includes:
1. verifying whether the format of the first transaction message is the format specified by the ODIN data block, namely verifying the validity of the message;
2. the identity of the source address in the first transaction message is verified, and specifically, the public key is used to verify whether the first transaction message is sent from the source address.
In addition, the cluster receives, in real time, a transaction message sent by the electronic device, where the transaction message includes a first transaction message and a second transaction message, the first transaction message is sent by the electronic device in this embodiment, and the second transaction message is sent by an electronic device other than the electronic device in this embodiment. Wherein the number of second transaction messages is not limited.
And determining which second transaction messages are received in the same time period as the received first transaction message according to the acquired time of each second transaction message.
S13, determining a prefix part in the named identifier of the first transaction message according to the first transaction message, all the second transaction messages and the existing block chain, so that the electronic equipment generates a complete named identifier of the first transaction message according to the determined prefix part;
wherein the naming identifier includes a naming hierarchy, a prefix portion, and a suffix portion.
The constituent structure of the named identifier is now explained in connection with fig. 2.
ODIN is a unique name for a data resource object in a network, complying with the Uniform resource identifier, URI, specification. The ODIN identifier is composed of a naming system, a prefix and a suffix, as shown in the first-level ODIN domain name in FIG. 2.
A Naming System (Naming System) is used for identifying the characteristics of the ODIN domain name, and indicates that the ODIN domain name is adopted to locate the network resource, and the fixed value is a character string 'ppk'. The value does not conflict with any current network protocol prefix, and all resource identifiers starting with "ppk" are processed according to the ODIN domain name rule. The naming system is separated from the prefixes by a colon.
The prefix (prefix) is used for the unique identification of the resource owner, determined by the location where the ODIN Domain name registration transaction is written to the blockchain.
For the first-level ODIN domain name, the naming scheme of the prefix is:
BLOCK_SN.TRANS_INDEX
wherein, B L OCK _ SN is the number of the block where the ODIN domain name registration transaction is located, and TRANS _ INDEX is the offset of the ODIN domain name registration transaction located inside the block.
For an N-level ODIN domain name, the prefix consists of N parts, organized in order from left to right, separated by slashes. The naming scheme of the prefix is as follows:
PARENT_ODIN_PREFIX/SUB_BLOCK_SN.SUB_TRANS_INDEX
the method includes that a part _ ODIN _ PREFIX is a higher-level ODIN domain name PREFIX, a SUB _ B L OCK _ SN _ TRANS _ INDEX is a position in a current-level block chain where ODIN domain name registration transaction is located, and the naming mode is the same as the first-level ODIN domain name PREFIX.
Postfix (also called dss (data Suffix string)) is used for unique identification of internal resources of the same resource owner. Suffixes are optional, managed autonomously by the domain owner and guaranteed to be unique. When the destination address is empty, the domain name owner is the user sending the first transaction message, and when the destination address is not empty, the domain name owner is the user owning the destination address.
The suffix is named as:
[RESOURCE_ID]#[DATA_VERSION_SN.CHUNK_INDEX]
wherein, the RESOURCE _ ID is a RESOURCE identification number, is autonomously defined and guaranteed to be unique by a domain name owner, can be a number and a character string, but can not contain special characters such as "#", "/", and the like, and default represents default RESOURCEs; DATA _ VERSION _ SN is a resource VERSION number and is used for distinguishing different historical VERSIONs of the same resource, counting is started from 1, and the default represents the latest VERSION of the resource; CHUNK _ INDEX is a sub-data block INDEX, used for block transmission of larger-scale resources, counting from 0, and by default, indicates no data block or a full data block.
In addition, the user can expand the identification according to the requirement of the user. Based on the primary ODIN, the registrant of the primary ODIN can expand the self-defined secondary ODIN by utilizing the self-owned block chain, and write HASH keywords of a new block formed by batch packaging of the registration records of the secondary ODIN into the last bone stem block chain to obtain legal verification and ensure uniqueness. By analogy, a more multi-level ODIN identification can be formed.
After the naming identifier of the resource is determined, other users can determine the specific position of the resource according to the naming identifier of the resource, and then search the resource from the position, so as to realize the positioning and the request of the resource.
In this embodiment, the blockchain cluster determines a prefix portion in the named identifier of the first transaction message, so that the electronic device generates a complete named identifier of the first transaction message according to the determined prefix portion. Namely, the invention adopts the naming method of naming the identifier, and the user does not name the data at will, so that the data naming mode is more standardized.
Besides providing a canonical naming system, the invention also has the following advantages:
1. autonomy. The ODIN identifier is generated and managed autonomously by the applicant based on decentralized blockchain technology, and the generation and management rules are completely open without centralized control mechanism. Thus, organizations and individuals, except those in possession of the administrative keys, have no authority to control and tamper with.
2. And (4) safety. The owner of each ODIN identifier in the ODIN system correspondingly possesses a pair of public and private keys of asymmetric encryption technology, the data content which is automatically issued can be signed through the private key, and the individual who receives the data content can be verified through the public key. Thus, it can be ensured that the received data is trusted by the source and not tampered with.
3. Uniqueness. The ODIN identifier uniquely identifies an open access index of any data content object (e.g., text, pictures, sound, data, images, software, etc.) so that the data content object can be accurately identified and extracted by a person.
4. Is permanent. Because data resources in a network have great dynamics and a large amount of data is generated and invalid in a short time, the current technical scheme can change along with the change of attributes such as a holder of a data content object or a storage address, and data confusion is caused. In order to solve this problem, the ODIN identifier is generated once and remains unchanged, and does not change with changes in attributes such as the holder of the data content object identified by the ODIN identifier or the storage address, and the permanence is ensured.
5. Compatibility. In the prior art, the MAC address is adopted to name the sensor, so that the functions of discovering and identifying the sensor equipment are realized, but the method is only suitable for a local network and cannot be used as a universal naming method for the Internet. The ODIN system is compatible with existing identifiers (e.g., international standard book number ISBN, international standard publication number ISSN, international standard text code ISTC, publisher identifier PII, etc.).
6. Interoperability (interoperability). The existing scheme adopts a resource naming method of fixed-length digital coding, the naming process depends on the centralized allocation of a management mechanism, the efficiency is not high, the total number of names has an upper limit, and the data generation and failure speed is difficult to adapt. However, the ODIN processing system can be compatible with different computer operating systems on the network while processing the same data and with different time-varying technical systems.
7. And (4) dynamically updating. The prior art scheme depends on the existing domain name system, and shows that the provider section and the classification section are defined by the domain name of the server, so that the information name resolution process needs to be completed by means of the domain name resolution system, and the resolution efficiency is not high. However, the ODIN system can make fast dynamic updates to its metadata, applications, and service functions.
Alternatively, on the basis of the embodiment of the resource naming method, referring to fig. 3, step S13 may include:
s21, packaging the first transaction message and all the second transaction messages to generate a block;
specifically, the first transaction message and all the second transaction messages are sequentially arranged and packaged to generate the block.
S22, executing a block chain consensus operation on the generated blocks to add the blocks into the existing block chain and generate a new block chain;
the blockchain consensus operation is to determine a destination blockchain node from all blockchain nodes, and enable all blockchain nodes to acknowledge the destination blockchain node, and add a blockchain to the block in all blockchain nodes.
Optionally, on the basis of this embodiment, step S22 includes:
1) determining a target blockchain node from at least one blockchain node;
specifically, the POW algorithm may be used to select the target blockchain node. When the target block chain node is selected, the target block chain node can be selected randomly, or the target block chain node can be determined through a certain workload certification or an authorized share certification.
2) The target block chain node sends the generated block to all other block chain nodes;
wherein the target blockchain node sends the generated block to all other blockchain nodes, so that each blockchain node owns the block.
3) And respectively adding the blocks into the respective existing block chains by the target block chain node and the block chain link points of the received blocks to generate a plurality of same new block chains.
Specifically, each block link adds the block owned by itself to the tail end of each stored block chain, forming a plurality of new identical block chains.
S23, generating a prefix portion in the named identifier of the first transaction message according to the location of the tile in the new tile chain and the location of the first transaction message added to the tile.
Specifically, the blocks record legitimate transactions and are packaged into blocks linked to the chain, with the number of transactions in a particular block being determined by the rules of the different block chains.
A prefix portion in the named identifier of the first transaction message is generated based on the location of the tile in the new chain of tiles and the location of the first transaction message added to the tile. Namely, the number of the block where the first transaction information is located and the offset located inside the block are determined.
It should be noted that, in the present embodiment, the steps S22 and S23 are an implementation manner of determining the prefix portion in the named identifier of the first transaction message according to the generated tile and the existing tile chain, and in addition, other implementation manners may also be used to determine the prefix portion in the named identifier of the first transaction message according to the generated tile and the existing tile chain.
