Developing Web3 Applications: A Technical Guide for TRON​

Introduction​

With the rise of decentralized applications (dApps) and blockchain technology, Web3, as the core concept of the next-generation internet, is transforming the way we interact with the digital world. Web3 is not just a technological trend; it represents a new value system and economic model. As one of the leading public blockchains globally, TRON is providing essential infrastructure for the development of Web3.

In this technical blog, we will walk you through how to develop Web3 applications on TRON, covering key concepts, the development process, tools, and resources. This guide will help developers enter the TRON ecosystem and start building and deploying their own Web3 applications.

1. What is Web3 and TRON?​

Introduction to Web3​

Web3 refers to the decentralized internet, aiming to give users control over their data and identity through blockchain technology. In Web3, decentralized applications (dApps) replace traditional centralized applications. Web3 emphasizes trustlessness, decentralization, and direct interactions between users and applications via smart contracts and cryptocurrencies.

Introduction to TRON​

TRON is a public blockchain designed to build a decentralized internet and storage infrastructure. It features a high-performance architecture that provides fast and low-cost transactions while supporting smart contract development. TRON is compatible with Ethereum’s smart contracts (ERC-20 and ERC-721), making it easy for developers to migrate or interoperate with applications on other blockchains.

With its high throughput and low transaction fees, TRON has attracted numerous dApp developers and is becoming a critical part of the Web3 ecosystem.

2. Developing Web3 Applications on TRON​

To develop Web3 applications on TRON, you need to understand the following key concepts and tools:

(1) Smart Contracts​

TRON allows developers to write smart contracts in Solidity, making it Ethereum-compatible. Smart contracts are self-executing code that automates transaction and data storage operations in a trustless manner.

How to Develop TRON Smart Contracts:

• Solidity Programming: TRON supports Solidity-based smart contract development, fully compatible with Ethereum. You can use existing tools and libraries like Remix and Truffle to write and test TRON smart contracts.

• Deploying Contracts: After writing a smart contract, you can deploy it to TRON’s mainnet or testnet using TRON’s deployment tools.

(2) TRC-20 and TRC-721 Standards​

TRC-20 is the token standard on TRON, similar to Ethereum's ERC-20, which allows you to create transferable tokens. TRC-721 is the non-fungible token (NFT) standard, allowing you to create unique and trackable digital assets.

• TRC-20 Tokens: You can create your own token and perform transfers or other operations on the TRON network.
• TRC-721 NFTs: You can create and trade non-fungible digital assets like digital art, in-game items, etc., using TRC-721.

(3) Web3.js and TronLink Wallet​

To interact with the TRON blockchain, you will need to use a JavaScript library like Web3.js (or TronWeb) to interface with the blockchain from a web browser.

TronWeb is similar to Web3.js and enables web developers to easily interact with the TRON blockchain, smart contracts, accounts, and transactions. With TronWeb, you can send transactions, query balances, and call smart contract functions.

TronLink Wallet is the primary wallet plugin in the TRON ecosystem, allowing users to easily connect to the TRON blockchain and manage TRX and TRC-20/721 tokens. As a Web3 developer, you can interact with users through TronLink wallet to send transactions, authorize operations, etc.

3. Core Features of TRON Blockchain​

(1) High Throughput and Low Transaction Fees​

TRON’s design optimizes for high throughput, allowing it to handle thousands of transactions per second (TPS). Compared to other blockchains like Ethereum, TRON offers lower transaction fees, making it an ideal choice for developing dApps.

(2) Efficient Resource Management Model​

TRON has a resource model that includes Energy and Bandwidth, which are the core resources required to perform transactions and execute smart contracts. Users can acquire these resources by staking TRX or by directly purchasing energy through services like CatFee.IO.

• Energy: Used to pay for smart contract execution fees.
• Bandwidth: Used to pay for regular transfer transactions.

On TRON, users can adjust their resource usage based on their needs, ensuring a seamless transaction experience without worrying about network congestion or high fees.

(3) Cross-Chain Interoperability​

TRON supports cross-chain interoperability, which means you can easily transfer assets between TRON and other blockchains. For example, through TRON's cross-chain bridge, users can move assets from Ethereum to TRON and vice versa.

4. Deploying TRON dApps​

To deploy a TRON dApp, follow these basic steps:

(1) Develop Smart Contracts​

Write smart contracts using Solidity or other supported programming languages, ensuring the functionality and security of the contract.

(2) Test the Contract​

Test the contract on TRON’s testnet to ensure it performs as expected in a live environment.

(3) Interact with the Front-End​

Use TronWeb to integrate TRON blockchain functionality into your web application, allowing you to interact with smart contracts, send transactions, and more.

(4) Deploy to Mainnet​

Once testing is complete, deploy the contract to the TRON mainnet, and users can begin interacting with your dApp.

TRON Dynamic Energy Model: Optimizing Resource Consumption and Improving Network Efficiency​

What is the TRON Dynamic Energy Model?​

The TRON (波场) Dynamic Energy Model (TIP-491) is a mechanism that dynamically adjusts the future energy consumption of a contract based on its known energy usage. This mechanism aims to prevent excessive resource consumption by a few contracts, thereby ensuring the robust, stable, and balanced development of the ecosystem. In this article, we will dive into the working principles of the Dynamic Energy Model, related APIs, and how the community is preparing for its implementation, while also introducing how you can optimize your TRON transaction experience by purchasing and managing energy through CatFee.IO.

Why is the Dynamic Energy Model Needed?​

Currently, over 85% of resource consumption on the TRON network is concentrated in a few contracts, and some of the transactions calling these contracts are of low value or even fraudulent. If this continues, it will not only affect user experience but also hinder the healthy growth of the TRON dApp ecosystem. Network capacity is limited, and when it’s filled with a large number of low-value transactions, other transactions will have to wait longer, leading to a poor experience for users.

By introducing the dynamic energy model, low-value transactions will incur higher costs, thereby reducing their impact on the network, and ensuring the smooth operation of other dApps. In this way, the dynamic energy model helps improve the allocation of network resources, preventing over-concentration of resources on a few contracts, and ensuring the ecosystem remains diverse, robust, and well-balanced.

Moreover, CatFee.IO, as a leading energy provider in the industry, offers reliable energy purchasing services, enabling users to easily acquire the energy they need during times of network congestion, thus avoiding transaction failures caused by insufficient energy.

How Does the Dynamic Energy Model Work?​

The Dynamic Energy Model introduces an energy_factor variable for each contract, which starts at 0. The final energy consumption when a user calls a contract is calculated as follows:

Transaction energy consumption = Transaction energy consumption * (1 + energy_factor)

During the TRON network's maintenance period (currently 6 hours), if the basic energy consumption of a contract exceeds a certain threshold, the energy_factor will increase in the next maintenance period. After this increase, users will consume more energy when sending the same transaction. However, the energy_factor will not increase indefinitely, as it has a maximum value. If the basic energy consumption of the contract falls below the threshold in a maintenance period, the energy_factor will gradually decrease, eventually returning to 0.

Advantages of CatFee.IO​

CatFee.IO provides a convenient service for purchasing and leasing energy for TRON users. When a contract consumes too much energy or the network is congested, you can quickly buy the necessary energy from CatFee.IO, ensuring that your transactions go through smoothly. Compared to burning TRX directly for energy, CatFee.IO offers more transparent and stable prices, reducing the additional costs caused by network fluctuations.

For example, if you need to make a large USDT transfer and the destination address doesn’t hold USDT, you might need up to 130,000 energy. Through CatFee.IO, you can easily purchase this energy and ensure a smooth transaction process.

How is the Energy Factor Calculated and Controlled?​

In the Dynamic Energy Model, the energy_factor for each contract is dynamically adjusted based on the contract's resource usage. The calculations for adjusting the energy_factor are as follows:

1. Increasing energy_factor: When the basic energy consumption of a contract exceeds the threshold, the energy_factor increases. The formula is:

   energy_factor = min((1 + previous_energy_factor) * (1 + increase_factor) - 1, max_factor)

2. Decreasing energy_factor: When the basic energy consumption of a contract falls below the threshold, the energy_factor decreases. The formula is:

   energy_factor = max((1 + previous_energy_factor) * (1 - decrease_factor) - 1, 0)

This mechanism ensures that a contract's energy consumption is dynamically adjusted based on its historical usage, helping to allocate resources more efficiently and avoid resource over-concentration.

How to Optimize Energy Management with CatFee.IO?​

If you often encounter transaction failures due to insufficient energy, you can quickly purchase the energy you need through CatFee.IO. For example, when transferring USDT, if the recipient address does not hold USDT, you may need up to 130,000 energy. By purchasing energy through CatFee.IO, you can ensure that your transactions are processed smoothly.

Compared to burning TRX for energy, purchasing energy through CatFee.IO is typically more efficient and cost-effective. You can choose the appropriate energy package according to your needs, minimizing the risk of additional costs caused by network congestion or fluctuations.

How to Obtain Chain Parameters of the Dynamic Energy Model?​

Once the dynamic energy model is enabled, users can call the /wallet/getchainparameters API to get related network parameters, as shown below:

$ curl -X POST http://127.0.0.1:8092/wallet/getchainparameters
{
   "chainParameter": [
       ……
       {
           "key": "getDynamicEnergyThreshold",
           "value": 2000000
       },
       {
           "key": "getDynamicEnergyIncreaseFactor",
           "value": 2000
       },
       {
           "key": "getDynamicEnergyMaxFactor",
           "value": 25000
       }
   ]
}

These parameters help you understand the energy usage on the network, and make adjustments according to your needs. If you'd like to know more about how to use CatFee.IO to obtain these parameters and optimize your energy management, feel free to reach out to us.

How to Prepare for the Dynamic Energy Model?​

The dynamic energy model will be deployed in a future version of TRON and enabled through network governance voting. dApp users don’t need to make special preparations, but they should understand the working principles of the dynamic energy model. When the model is activated, if a user interacts with a heavily used contract, the energy consumption for the same type of transaction may vary in different periods due to the penalty mechanism.

Wallets, exchanges, and dApps involved in estimating and displaying transaction fees should include the energy fee generated by punitive consumption when estimating TRC20 token transfer and smart contract call fees. Additionally, if you need to show the breakdown of transaction fees to users, punitive energy consumption should also be considered and displayed.

Conclusion​

The TRON Dynamic Energy Model optimizes network resource allocation by dynamically adjusting the energy consumption of contracts based on their historical usage. By increasing the cost for resource-intensive contracts, it reduces their future resource occupation without affecting other dApps. This model makes the allocation of energy resources on the chain more efficient, prevents over-concentration of network resources, and ensures the balanced development of the TRON ecosystem.

By combining CatFee.IO's energy purchasing services, TRON users can more efficiently manage their energy consumption, ensuring smooth transactions even during times of high demand. Whether you're a dApp developer or an average user, understanding the dynamic energy model and leveraging CatFee.IO for energy management is key to optimizing your TRON transaction experience.
