Understanding TRON: A Comprehensive Guide to the Blockchain Ecosystem

·

TRON is a decentralized, open-source blockchain protocol established by Justin Sun in 2017. Designed as a blockchain-based operating system, its primary mission is to decentralize the internet and create a robust infrastructure for decentralized applications (DApps). The TRON protocol has gained global recognition for its high efficiency, scalability, and minimal transaction fees. It also enhances compatibility with Ethereum smart contracts through a flexible and pluggable smart contract platform.

By leveraging blockchain and distributed storage technologies, TRON has developed a worldwide entertainment ecosystem that enables free content sharing. This system empowers users to freely publish, store, and own data, while also facilitating the subscription, distribution, and trading of digital assets in a decentralized, autonomous manner.

How the TRON Network Operates

Similar to Ethereum, developers can build applications on the TRON protocol. Network nodes are responsible for packaging transactions and producing blocks to ensure operational stability. A key differentiator for TRON is its consensus mechanism. While Ethereum initially used Proof-of-Work (PoW), TRON introduced a modified Delegated Proof-of-Stake (DPoS) model.

Holders of TRX, TRON’s native cryptocurrency, can vote for 27 Super Representatives (SRs). These SRs maintain the network, process transactions, and generate blocks. In return, they receive TRX as rewards.

Becoming a Super Representative

Any account in the TRON network can apply to become a Super Representative candidate or vote for one. The top 27 candidates with the most votes become SRs and gain block production rights. Candidates ranked 28th to 127th are designated as partners, while the remainder are candidates. Votes are tallied every six hours, meaning the list of SRs updates at the same interval.

Voting and Reward Distribution

To vote, an account must hold TRX tokens. By freezing TRX, users obtain TRON Power (TP)—1 TP for each frozen TRX. The more TP a candidate accumulates, the higher their ranking. Unfreezing TRX results in the loss of TP and invalidates any votes cast in the current round.

Block rewards in TRON are distributed to SRs and partners each time a new block is created. These rewards come from two sources:

  1. Block Rewards: SRs receive 16 TRX per block generated. They may keep a portion of this reward and distribute the remainder to their voters based on a predetermined commission ratio.
  2. Vote Rewards: SRs and partners receive 160 TRX per block. These rewards are allocated according to the number of votes received, and are subsequently distributed to voters after deducting the commission ratio.

The commission ratio—typically set at 20% by default—is the percentage SRs and partners retain for themselves. Candidates may adjust this ratio to attract more voters; a lower ratio means more rewards for supporters.

Calculating Block Rewards

The TRON network produces a block every three seconds, resulting in 28,800 blocks per day. With each block yielding 16 TRX, daily block rewards total 460,800 TRX. Assuming the default 20% commission ratio, daily rewards for an SR and their voters are:

Calculating Vote Rewards

SRs also earn 160 TRX per block from vote rewards, totaling 4,608,000 TRX daily. Using the default commission ratio, vote rewards are calculated as:

TRX Tokenomics and Utility

TRX is TRON’s native utility token, with a total supply of 100 billion. It was initially distributed through a 2017 ICO that raised $70 million. After the mainnet launch in June 2018, TRX’s price experienced steady growth. Between 2018 and 2020, its value remained relatively stable amid a subdued market. However, the 2021 bull run—driven by the rise of DeFi, GameFi, and NFTs—propelled TRX to an all-time high of $0.18. It currently trades around $0.07.

New TRX is minted through network maintenance (460,800 TRX daily) and voting mechanisms (4,608,000 TRX daily). TRX holders can use the token to access network resources.

Resource Allocation

Transactions and interactions on TRON consume resources, which are categorized into three types:

  1. Storage: Used for on-chain data storage. Unlike bandwidth and energy, storage does not require TRX purchases due to TRON’s unique memory model.
  2. Bandwidth: Measures the size of transaction data stored on the blockchain. Larger transactions consume more bandwidth.
  3. Energy: Quantifies the computational power required by the TRON Virtual Machine (TVM) to execute operations. Smart contract transactions consume energy.

Bandwidth Points

Each account receives 1,500 free bandwidth points daily. If this allowance is exhausted, users must burn TRX to acquire additional bandwidth. Stake TRX to obtain more bandwidth.

Bandwidth usage priority is as follows:

  1. Bandwidth from staked TRX
  2. Free daily bandwidth
  3. TRX burning (if bandwidth is insufficient)

All transactions except queries consume bandwidth. For example, transferring TRX requires the sender to pay bandwidth costs—similar to Ethereum’s gas fees.

Energy

Smart contract execution consumes energy based on computational complexity. There is no free energy; users must stake TRX to obtain it. If energy reserves are insufficient, TRX must be burned to cover costs.

Token issuance is a primary use case for energy, as creating and interacting with token contracts requires significant computational resources.

TRON’s Development Timeline and Roadmap

Since its inception in 2017, TRON has evolved into a top-tier public blockchain by market capitalization. Key milestones include:

TRON’s long-term vision unfolds across six phases:

  1. Exodus: Distributed content sharing via peer-to-peer storage (e.g., IPFS)
  2. Odyssey: Economic incentives for content creation and distribution
  3. Great Voyage: Transition from "fan economy" to "fan finance"
  4. Apollo: User-generated token issuance and value transfer
  5. Star Trek: Decentralized prediction markets and gambling platforms
  6. Eternity: Decentralized gaming platforms and crowdfunding

Key Applications and Ecosystem Features

TRON ranks among the top 15 blockchains globally. Its high throughput, scalability, and low fees have enabled diverse applications in payments, decentralized exchanges, gaming, and wallets. Examples include the Spend credit card (TRX payments), TRON ATMs, and Peiwo’s TRX-based virtual gifts.

TRC-20 Token Standard

TRC-20 is TRON’s technical standard for token contracts. It is widely adopted, most notably by Tether’s USDT stablecoin. As of 2022, over 32 billion USDT tokens were issued on TRON, rivaling Ethereum’s ERC-20 USDT supply.

SunSwap DEX

SunSwap is TRON’s first decentralized exchange protocol. It enables instant swaps between TRC-20 tokens without commissions. Users can provide liquidity or trade to earn rewards. Its total value locked (TVL) exceeds $800 million.

USDD Stablecoin

USDD is an over-collateralized decentralized stablecoin backed by BTC, USDT, and TRX at a minimum 130% collateral ratio. Managed by TRON DAO Reserve, it operates across multiple blockchains. Its current collateral ratio exceeds 300%.

JustLend Lending Protocol

JustLend is TRON’s official lending platform, allowing users to earn interest on deposits and borrow assets. Its total deposit volume exceeds $3.6 billion.
