Background
Smart contracts are key components of blockchain technologies and applications that allow trusted transactions to be conducted without third parties, which transactions do not require human intervention, are traceable, are irreversible, etc. The concept of Smart Contracts was first introduced in 1995 by Nick Szabo, "a Smart contract is a set of commitments (commitments) defined in Digital form, including agreements on which contract participants can execute the commitments" (Nick Szabo: "Smart Contracts: Building Blocks For Digital marks"), which has greater execution power and reduced transaction costs than conventional Contracts. The block chain technology provides the most critical credible environment for executing the intelligent contract, and paves the way for the wide application of the intelligent contract.
The content of the intelligent contract is a business contract based on a business process, and the expression form of the intelligent contract is a piece of executable computer code. The mismatch in the knowledge field is a challenge in the application of intelligent contracts and increases the risk of the intelligent contracts. The main problems encountered during conventional intelligent contract management are as follows:
1. the intelligent contract has no visual design interface, the contract development must rely on technical personnel, the risk of mismatching of contract business and code logic is caused, deviation is generated, an effective management mechanism is lacked, human errors are difficult to avoid, and the difficulty of business popularization is large.
2. The development, deployment and debugging of the intelligent contract are complicated, and the difficulty in development, deployment and debugging is further increased because the block chain is distributed.
3. The intelligent contract development and implementation technologies of different block chain platforms are different, and a uniform implementation standard does not exist, so that the difficulty of cross-chain data interaction is increased.
Therefore, if the creation of the intelligent contract can be freed from the limitation that the programmer is required to participate, and the intelligent contract is more intelligent in the management of the whole life cycle of the intelligent contract, the intelligent contract has a significance which cannot be underestimated for the popularization of the intelligent contract.

Example 2
Intelligent contract management system based on containerization technology
As shown in fig. 3, the present embodiment provides an intelligent contract invocation flow based on containerization technology, which includes the following steps:
step 201: the on-chain application initiates a call request. The application on the chain wants to call the intelligent contract to realize the interaction with the block chain, and the application initiates a contract calling request gateway through the API gateway and inputs the parameter information of the situation. The API gateway matches the containers of the standard intelligent contracts.
Step 202: the API gateway routes standard contract services. The API gateway registers standard intelligent contract service, binds the services of the gateway and sets a routing path, and the API gateway searches the corresponding standard intelligent contract service according to the routing table.
Step 203: the standard intelligent contract invokes the adapter. And after receiving the data interaction request with the block chain account book, the standard intelligent contract calls an adapter of the matching chain. The adapter encapsulates the calling interface implementation of the underlying chain, and can provide convenient chain calling service.
Step 204: the adapter calls an on-chain intelligent contract. And after receiving the call request of the standard intelligent contract, the chain adapter calls the contract on the corresponding chain to realize the data operation of the ledger through the anchoring relation between the standard intelligent contract and the contract on the chain.
Step 205: the on-chain intelligent contract operates on block chain account data. After the on-chain contract receives the request transmitted by the adapter, the block chain account data is operated, including the inquiry of the data on the uplink chain of the data and the like. The record of the operation is written into the block, the result of the operation is returned upwards step by step, and the processing result is directly received by the application.
Step 206: data of the contract operation under the chain. After the contract on the standard intelligent contract calling chain carries out data interaction with the account book, the operated data is packed simultaneously to be used as an operation data set of the standard contract, the data on the chain and the data under the chain are mapped and anchored one by one and written into a database under the chain to be used as data backup and buffering on the chain.
