The Ethereum smart contract operation process includes six main steps: 1. The development preparation stage requires the installation of Node.js, Solidity compiler, configuration of the development environment and preparation of storage; 2. The contract writing and compilation requires the use of the Solidity language to define the structure and generate bytecode and ABI; 3. The deployment of the contract requires connection to the network, creation of transactions, and signature to obtain the deployment address; 4. The contract interaction is divided into read (call) and write (sendTransaction) operations; 5. Monitoring and event processing involves listening to events and querying transaction status; 6. Security considerations include testing logical vulnerabilities, setting gas parameters, permission control and using security libraries.

Detailed explanation of the operation process of Ethereum smart contract

1. Development preparation phase

Before operating an Ethereum smart contract, developers need to complete the following preparations:

  • Install Node.js and npm/yarn package manager

  • Install Solidity compiler (solc) or use Remix online IDE

  • Configure development environments (such as Truffle, Hardhat, or Foundry frameworks)

  • Prepare Ethereum storage (MetaMask, etc.) and obtain testnet ETH

2. Contract writing and translation

Operation process:

  1. Writing smart contract code (.sol file) using Solidity language

  2. Define contract structures, state variables, functions, and events

  3. Compile Solidity code into EVM bytecode and ABI interface via compiler

 // Example: simple storage contract pragma solidity ^0.8.0;contract SimpleStorage {
    uint storedData;

        function set(uint x) public {
        storedData = x;
    }

        function get() public view returns (uint) {
        return storedData;
    }}

3. Deploy the contract

Operation steps:

  1. Connect to the Ethereum network (main network or test network)

  2. Interact with blockchain using Web3.js or Ethers.js library

  3. Create a contract to deploy transactions, including:

    • Compiled bytecode

    • Constructor parameters (if any)

    • Specified gas limit and gas price

  4. Signing transactions with storage private key

  5. Broadcast transactions to the network and wait for miners to pack

  6. Get the contract deployment address (contractAddress in transaction receipt)

4. Contract interaction

Main operation methods:

Read operation (call): free query of contract status

javascript
 const value = await contract.methods.get().call()

Write operation (sendTransaction): Gas fee needs to be paid to modify the status

 await contract.methods.set(123).send({from: account})

5. Monitoring and event handling

  • Listen to contract events:

javascript
 contract.events.EventName({
    filter: {key: value},
    fromBlock: 'latest'}, (error, event) => console.log(event))
  • Query transaction status:

 const receipt = await web3.eth.getTransactionReceipt(txHash)

6. Safety precautions

  • Strictly test contract logic to avoid loopholes such as reentry

  • Set gas limits and gas prices reasonably

  • Add permission control for important operations

  • Consider using security libraries like OpenZeppelin

The complete operation process involves multiple links of development, testing, deployment and interaction, and each step needs to be handled with caution to ensure the contract runs safely and reliably.

Huawei HarmonyOS 6 system cancels the 'NEXT' suffix: It will be native Hongmeng in the future Huawei HarmonyOS 6 system cancels the 'NEXT' suffix: It will be native Hongmeng in the future Sep 24, 2025 pm 04:12 PM

The latest news on September 18th, Huawei HarmonyOS6 has launched multiple rounds of preview version push for developers, and has recently opened the experience qualification to some users who have tried it out for the first time. According to user feedback, the current system name no longer displays the "NEXT" suffix, and it is officially renamed to HarmonyOS6.0. Huawei initially proposed the name HarmonyOSNEXT for the first time at the developer conference in August 2023, aiming to mark the Hongmeng system entering a new stage of development and realizing true native self-development. HarmonyOSNEXT's most core breakthrough is to completely adopt the underlying system architecture developed independently, completely remove the Linux kernel and Android AOSP code, and only run applications based on the HarmonyOS kernel.

Win10 Blue Screen: Kernel Win10 Blue Screen: Kernel Sep 25, 2025 am 10:48 AM

Everyone knows that there are many types of blue screen phenomena in Windows 10. When blue screen occurs, many people often don’t know how to deal with it. Since most of the code displayed on the blue screen is obscure and difficult to understand, many users are confused and difficult to solve the problem on their own. Today, let’s talk about how to effectively deal with Kernel_Security_check_Failure blue screen code. This blue screen code usually indicates that there are problems with the driver, and the most common errors are network cards and graphics drivers. The reasons for the KERNEL-SECURITY-CHECK-FAILURE blue screen may be as follows: There are compatibility issues with network card drivers. The graphics card driver version does not match or is damaged. In response to this situation,
