4. Participate in the Ethereum community

Participation in the Ethereum community is the key to entering the Ethereum world. You can follow Ethereum-related social media, forums, blogs, etc., participate in discussions and exchanges, and learn about the latest Ethereum technologies and projects.

When using Ethereum to carry out the above activities, you need to pay attention to protecting your asset security and privacy, do not disclose or transmit the private key to others at will, and ensure that you use a safe trading platform and legal tokens.

What can I do to get into Ethereum?

On Ethereum, you can do the following:

1. Use Ethereum (ETH) for transactions, such as buying and selling digital currencies, participating in decentralized financial (DeFi) applications, etc. The following are some examples and suggested analysis tools.

(1) Common cryptocurrency exchange references:

Coinbase, Binance, Kraken, Bitfinex, etc. are examples.

These exchanges provide convenient trading methods and multiple digital currency trading pairs, and also provide relatively complete security and customer support.

(2) Common decentralized exchanges:

Uniswap, SushiSwap, Curve, etc. are just examples.

These decentralized exchanges do not require centralized intermediaries, but implement transaction functions through smart contracts. The advantages of decentralized exchanges include that buyers and sellers can conduct transactions directly, and the transaction process is more secure, open and transparent, etc., but the transaction volume is relatively small compared with centralized exchanges.

Here are some popular cryptocurrency exchange analysis and usage analysis websites:

(1) CoinMarketCap: It is used to analyze the overall situation of the cryptocurrency market, including market value ranking, price trend, trading volume, etc., and can also obtain basic information of exchanges.

(2) CoinGecko: Similar to CoinMarketCap, it provides real-time cryptocurrency prices, market capitalization, and trading volume information, as well as information on exchanges, projects, and indicators.

(3) CryptoCompare: Provide information on the cryptocurrency market, including price, market value, trading volume, exchange information, etc.

(4) Nomics: Provide real-time data and historical data of the cryptocurrency market, including price, market value, trading volume, exchange data, etc.

(5) DappRadar: used to track the use of decentralized applications (Dapps) on the blockchain, including information such as the type of Dapp, number of users, and transaction volume.

(6) DeFi Pulse: It is used to track the usage of decentralized finance (DeFi) projects, including the project's locked funds, number of users, transaction volume and other information.

(7) Debank: It is a cryptocurrency data analysis platform that provides various cryptocurrency and decentralized finance (DeFi) data. Its main functions include wallet management system, data analysis, etc.

These sites provide a wealth of data and analytical tools that can help users better understand cryptocurrency markets and exchange usage.

2. Create your own tokens and issue and trade them on Ethereum through smart contracts.

To create your own token on Ethereum, you can follow these steps:

The following is an example of Ethereum token creation, including four steps:

(1) Determine the token specification

First, we need to determine the specifications of the token. In this example, we use the ERC-20 standard to create tokens. ERC-20 is one of the most commonly used token standards on Ethereum. It defines the basic functions and operation methods of tokens, such as token names, symbols, total supply, balance inquiries, transfers, and more.

(2) Deploy smart contracts

Next, we need to use the Solidity language to write the token smart contract, and use the Ethereum development tools to compile and deploy.

Suppose we have written a contract called MyToken using Solidity, which contains the functions and operations defined by the ERC-20 standard. Then we can use Remix in the Ethereum development tools to compile smart contracts, and use tools such as Ganache to simulate the Ethereum network for deployment and testing.

(3) Test tokens

Before deploying to the main network, we need to use the Ethereum test network for token testing to ensure that its functions and operations are working properly.

We can use the Metamask wallet in the Ethereum development tool to connect to the Ethereum test network (such as Rinkeby, Kovan, etc.), and then use the test function in Remix to test operations such as token transfers and balance inquiries. During the testing process, attention needs to be paid to whether there are bugs or vulnerabilities to ensure the security and reliability of the token.

(4) Issue tokens

When the token smart contract is tested, we can deploy it to the Ethereum mainnet, allowing others to trade and use the token on Ethereum.

Before deploying the contract to the main network, it is necessary to ensure that there is enough ETH in the Ethereum wallet to pay the transaction fee (Gas Fee). Then we can use tools such as Truffle in the Ethereum development tools to deploy smart contracts to the Ethereum main network. After successful deployment, we can find the address of the token contract we created on the Ethereum blockchain and start trading and using the token on Ethereum.

The above is an example of Ethereum token creation, which includes four steps: determine token specifications, deploy smart contracts, test tokens, and issue tokens. This example is for reference only, and needs to be adjusted according to specific situations in actual operation.

3. Develop smart contracts to realize multiple functions, such as decentralized voting, gambling, coordination, etc.

The following is an example of a simple smart contract that can be used to store and query an integer value:

1// SPDX-License-Identifier: MIT

2pragma solidity ^0.8.0;

3

4contract SimpleStorage {

5 uint256 private value;

6

7 function setValue(uint256 newValue) public {

8 value = newValue;

9 }

10

11 function getValue() public view returns (uint256) {

12 return value;

13}

14}

In this contract, the value variable is used to store an integer value, the setValue function is used to set the value value, and the getValue function is used to get the value value.

It can be compiled to bytecode using the Solidity compiler, and the bytecode can then be deployed on the Ethereum network. After deployment, the value can be set and retrieved by calling functions on the smart contract.

4. Participate in the Ethereum community, contribute to the development of blockchain technology, participate in open source projects, social media, forums, etc.

To get involved in the Ethereum community, here are some suggestions:

(1) Learning Ethereum and smart contracts: To participate in the Ethereum community, you need to be familiar with Ethereum blockchain technology and smart contract development. You can learn by reading relevant technical documents, taking online courses, and practicing writing smart contracts.

(2) Participate in community activities: Participate in online and offline activities of the Ethereum community, such as Meetups, online forums, developer conferences, etc. These activities allow you to communicate with other developers and gain new knowledge and opportunities.

(3) Participate in open source projects: You can find many open source Ethereum-related projects on GitHub, and you can participate in them and contribute to programming, document writing, testing, etc., which can give you a deeper understanding of the Ethereum ecosystem. and connect with other developers.

(4) Join social media: Join the social media of the Ethereum community, such as Twitter, Reddit, and Discord, follow and participate in discussions, and learn about the latest technology development, market dynamics, and community activities.

(5) Create your own projects: Use the knowledge you have learned and open source tools to create your own Ethereum projects, which can not only exercise your skills, but also contribute to the Ethereum community.

In conclusion, participating in the Ethereum community requires continuous learning and active participation, making connections and contributing to the community.

5. Combine Ethereum with other technologies to explore more application scenarios and business value, such as combining with the Internet of Things, artificial intelligence, supply chain, etc. There are many ways to connect Ethereum with other technologies. The following are some common The way:

(1) Using Oracles: Oracles is a bridge technology that can introduce external data into the blockchain, enabling Ethereum smart contracts to interact with other data sources. Through Oracles, Ethereum can interface with traditional data sources, APIs, IoT devices, and more.

(2) Interact with other blockchains: Ethereum can interoperate with other blockchains through cross-chain technology, such as realizing transactions between Ethereum and Bitcoin through atomic swaps. In addition, data between different blockchains can also be interconnected through consensus bridging technology.

(3) Use distributed storage technology: Ethereum can be combined with other distributed storage technologies, such as IPFS (InterPlanetary File System), through which distributed file storage and sharing can be realized.

(4) Integrate other blockchain applications: Ethereum can achieve richer functions by integrating other blockchain applications. For example, payment applications of other blockchains can be integrated to realize decentralized payment in Ethereum.

In short, to connect with other technologies on Ethereum, it is necessary to choose an appropriate connection method and carry out corresponding technical implementation and integration.
