The blocks are storage units one by one, and all communication information of all block nodes in a certain time is recorded. The blocks are linked by random hashing (also called hash algorithm), the latter block contains the hash value of the former block, and as the information exchange expands, one block is successive to one block, and the result is called a block chain.

Fig. 1 schematically illustrates a system architecture 100 suitable for use in the blockchain-based information processing methods and apparatus of embodiments of the present disclosure. It should be noted that fig. 1 is only an example of a system architecture to which embodiments of the present disclosure may be applied to assist those skilled in the art in understanding the technical content of the present disclosure, but does not mean that embodiments of the present disclosure may not be used in other devices, systems, environments, or scenarios.

Fig. 2 schematically shows a schematic diagram of a business architecture description model of an embodiment of the present disclosure.

As shown in FIG. 2, business architecture description model 200 may include textual descriptions and associations of business architecture flow model 201, product model 202, and entity model 203, which are currently in use in enterprises.

Flow model 201: the method refers to the fact that services in different service fields are divided based on planning, executing and supervising value flows of the services, each value flow is divided into different activities, tasks are decomposed in the activities, the tasks are decomposed into flow descriptions after steps according to service rules and conditions, and five levels (service fields-value flows-activities-tasks-steps) are shared.

For example, in the process model 201 of banking, the business domain generally includes, but is not limited to: personal deposit, personal account, credit card, personal loan, etc. Value streams generally include, but are not limited to: business planning, business preparation, service clients, etc. Activities generally include, but are not limited to: making a management system, issuing a credit card, withdrawing funds from the credit card, returning a credit card debt, and the like. Tasks generally include, but are not limited to: identifying individual customers, monitoring real-time fraud risk, accepting credit card funds withdrawal applications, settling foreign exchange, etc.

Product model 202 is a set of standard structures that define enterprise products, including product lines, product groups, base products, saleable products, and associations between products.

For example, in a banking product model 202, generally include, but are not limited to: debit cards, credit cards, quasi-credit cards, international debit cards, and the like.

The entity model 203 records the service content of each service object, and each service object includes a core entity, a life cycle (state of the core entity), subordinate entities (describing attribute information of the core entity), association relations among the service objects, and constraint conditions.

It should be noted that, the business architecture may include, in addition to the foregoing process model 201, product model 202, and entity model 203, a one-to-one association relationship or a one-to-many association relationship between the hierarchical members.

It should be noted that fig. 2 is only an example of a model included in the service architecture description model to which the embodiments of the present disclosure may be applied, so as to help those skilled in the art understand the technical content of the present disclosure, but it does not mean that the service architecture description model of the embodiments of the present disclosure may not include other models, and as the service is updated and extended, the model included in the service architecture description model is iterated and updated continuously.

In this context, it is to be understood that the terms involved in this invention include blockchain, blockchain networks, ledgers, smart contracts and consensus. Where a blockchain is a storage structure of encrypted, chained transactions formed by blocks. The header of each block can include the hash value of all transactions in the block and also the hash value of all transactions in the previous block, so that the tamper resistance and the anti-counterfeiting of the transactions in the block are realized based on the hash value; the newly generated transactions, after being filled into the block and passing through the consensus of the nodes in the blockchain network, are appended to the tail of the blockchain to form a chain growth. A blockchain network refers to a collection of nodes that incorporate new blocks into the blockchain by way of consensus. Ledgers are a collective term for blockchains (also known as ledger data) and state databases that are synchronized with blockchains. Wherein the blockchain records transactions in the form of files in a file system; the state database records transactions in the blockchain in the form of different types of key-value pairs for supporting quick queries for transactions in the blockchain. The intelligent contract, also called chain code or application code, is deployed in a node of the blockchain network, which is triggered to execute according to a condition, and the node executes the intelligent contract invoked in the received transaction to update or query the key value of the state database for data. Consensus refers to a process for agreeing on transactions in a blockchain among a number of nodes involved, the agreed blocks being appended to the tail of the blockchain, mechanisms for achieving consensus including workload certification, equity certification, stock authority certification, elapsed amount of time certification, and the like.
