Q & A

1.What are the triggering conditions for smart contracts?
It can be a time condition, specific transaction behavior, reaching a certain value, etc., such as executing a payment on a certain date or triggering a transfer when the account balance reaches a certain amount.

2.What is the execution environment of smart contracts?
Execute in the virtual machine of the blockchain, different blockchains have different virtual machines, such as Ethereum's EVM.

3.Can the code of smart contracts be modified?
It is generally difficult to modify, but some have upgrade mechanisms that require strict processes and designs to be followed.

4.How do smart contracts interact with external data?
Using a oracle to obtain external data, such as obtaining price information of goods in the real world.

5.What skills are required for the development of smart contracts?
Requires proficiency in programming skills (such as Solidity), understanding of blockchain principles, security knowledge, etc.

6.What is the storage method of smart contracts?
Stored on the blockchain in the form of bytecode, occupying a certain amount of block space.

7.What is the legal status of smart contracts?
At present, it is still under continuous development and definition, and some countries and regions have begun to recognize its legitimacy and effectiveness.

8.What are the costs of smart contracts?
This includes development costs, deployment costs (which may require payment of certain tokens as transaction fees), and possible maintenance costs.

9.What factors affect the running speed of smart contracts?
Affected by factors such as the performance of blockchain itself (such as TPS), contract complexity, network conditions, etc.

10.How can smart contracts achieve multi-user interaction?
Through the interface and functions of the contract, different users can call the functions of the contract to achieve interactions such as transactions and collaborations.
