Key points
- TRON is a blockchain network designed for smart contracts and decentralized applications, with its own token called TRX.
- TRX is used to pay for network resources, vote for block producers, and participate in governance.
- TRON is known for high throughput and low fees, but it has faced criticism over centralization and its association with Justin Sun.
What is TRON?
TRON is a public blockchain network that runs smart contracts—programs that execute automatically when conditions are met. It was created to support decentralized applications (dapps), digital entertainment, and content sharing without relying on a central authority. The network has its own cryptocurrency, called TRX, which is used to pay for transactions, secure the network, and take part in decisions about its future.
TRON’s market capitalization ranks it 8th among all cryptocurrencies, with 95,041,010,992 TRX in circulation. That makes it one of the largest blockchain projects by market value, though its technology and community differ from better-known networks like Ethereum.
How does TRON work?
TRON uses a consensus mechanism called Delegated Proof of Stake (DPoS). In simple terms, TRX holders who stake their coins vote for 27 “Super Representatives” (SRs), who take turns producing a block every three seconds. Votes are recounted every six hours, and a block becomes irreversible once 19 different SRs have built on it, usually in about a minute (TRON consensus documentation). This design allows TRON to process many transactions quickly and keep fees very low compared to networks that rely on energy-intensive mining.
The network runs the TRON Virtual Machine (TVM), which is largely compatible with the Ethereum Virtual Machine (EVM), meaning developers can port many Ethereum-based applications to TRON with minimal changes (the TRON docs list the differences). TRON also has its own token standards, such as TRC-20 for fungible tokens and TRC-721 for non-fungible tokens (NFTs). These are similar in purpose to Ethereum’s ERC-20 and ERC-721 standards.
To use the network, you need “resources” called Bandwidth and Energy. Every activated account gets 600 free Bandwidth, which refills over 24 hours; a simple TRX transfer uses about 270, so the free allowance covers about two a day. Smart contract calls, including every USDT transfer, also need Energy, which has no free allowance: you either stake TRX to get it or burn TRX to pay for it (resource model). Staking TRX also gives you voting power, which you can use to support Super Representatives. Unstaked TRX can be withdrawn 14 days later.
What a USDT transfer costs on TRON
USDT on TRON is a TRC-20 smart contract, so sending it uses Energy as well as Bandwidth. We checked 25 recent USDT transfers on 5 November 2026: each used 64,285 Energy when the recipient already held USDT and 130,285 Energy when it did not, plus about 345 Bandwidth. Without staked or delegated Energy, the network burns TRX at the current rates of 100 sun per Energy and 1,000 sun per Bandwidth (1 TRX = 1,000,000 sun), as listed in the TRON resource documentation.
| Transfer | TRX burned if you have no staked resources | In US dollars now |
|---|---|---|
| USDT to an address that already holds USDT | 64,285 × 100 sun = 6.43 TRX | $1.969 |
| USDT to an address that has never held USDT | 130,285 × 100 sun = 13.03 TRX | $3.9906 |
| Plain TRX transfer after the free Bandwidth is used up | About 270 × 1,000 sun = 0.27 TRX | $0.082701 |
If the sender’s free Bandwidth is also used up, a USDT transfer burns another 0.345 TRX or so for Bandwidth. TRX price as of 14 Nov 2026, 23:15 UTC. Staking TRX, or having Energy delegated by another account, lowers the cost a lot, which is why many wallets and exchanges do so. These rates are chain parameters that Super Representatives can change by vote, and TRON’s dynamic Energy model can raise the Energy that very busy contracts use. For Bitcoin and Ethereum costs right now, see our network fees page.
What is TRX used for?
TRX is the native asset of the TRON network. It serves several core functions:
- Paying for resources: Users burn or stake TRX to get Bandwidth and Energy for transactions and smart contracts.
- Staking and voting: Staking TRX grants voting rights to help elect Super Representatives, who secure the network (our staking guide compares this with other networks).
- Governance: TRX holders elect the Super Representatives, and the 27 active SRs propose and vote on changes to network parameters, such as fees and rewards, as an on-chain committee (TRON docs).
- Medium of exchange: TRX is traded on many exchanges and used within the TRON dapp ecosystem, including DeFi and gaming.
Unlike some tokens that are only used for fees, TRX also plays a central role in the network’s security and decision-making. The more TRX you stake, the more influence you have over which block producers operate the chain.
Notable history
TRON was founded in 2017 by Justin Sun, a Chinese-born entrepreneur. The project held an initial coin offering (ICO) in 2017, raising millions of dollars before launching its mainnet in 2018. Initially, TRX was issued as an ERC-20 token on Ethereum; after the mainnet launch, holders swapped those tokens for native TRX on the TRON blockchain.
In 2018, TRON acquired BitTorrent, the peer-to-peer file-sharing company, and later integrated its technology into the TRON ecosystem. The network has also been involved in high-profile partnerships and acquisitions, though some have drawn scrutiny. For example, in 2023, the U.S. Securities and Exchange Commission (SEC) charged Justin Sun and three companies he controls with fraud and unregistered securities offerings related to TRX and BitTorrent tokens. Sun denied the allegations. In March 2026 the SEC ended the case: under a proposed settlement, Rainberry (formerly BitTorrent Inc.) agreed to pay a $10 million civil penalty over wash trading of TRX in 2018 and 2019, without admitting or denying the allegations, and the SEC dismissed all claims against Sun, the Tron Foundation and the BitTorrent Foundation with prejudice (SEC litigation release 26496).
TRON has also become a major platform for stablecoin transfers, particularly Tether (USDT). A large share of USDT in circulation runs on TRON because of its low fees and speed (see our report on daily USDT transfer volumes and our stablecoin guide). This has made TRON a key piece of infrastructure for crypto trading and payments, especially in emerging markets.
Main risks and criticisms
TRON’s DPoS model, while efficient, has been criticized for being more centralized than Bitcoin or Ethereum. With only 27 Super Representatives producing blocks, a small number of entities can have significant influence over block production. Critics argue this makes the network less resistant to censorship and collusion.
The project’s close association with Justin Sun is another point of contention. Sun is a polarizing figure known for aggressive marketing and publicity stunts. The SEC case, although now closed, raised concerns about regulatory risk for TRX and related projects (see crypto regulation basics).
Additionally, some observers question the level of genuine decentralization in TRON’s dapp ecosystem, noting that many applications are controlled by a small group of developers. As with any blockchain, smart contract bugs, hacks, and scams are also risks. Users should do their own research before interacting with any dapp.
How TRON compares to alternatives
TRON is often compared to Ethereum, Binance Smart Chain (now BNB Chain), and EOS. All are smart contract platforms, but they differ in design and community.
| Feature | TRON | Ethereum | BNB Chain |
|---|---|---|---|
| Consensus | Delegated Proof of Stake | Proof of Stake | Proof of Staked Authority |
| Speed | A block every 3 seconds | A block every 12 seconds (base layer) | High |
| Typical fees | Simple transfers often free; token transfers need Energy (see above) | Variable, often higher | Low |
| EVM compatible | Yes | Yes (native) | Yes |
| Notable use | Stablecoin transfers, dapps | DeFi, NFTs, dapps | DeFi, dapps |
TRON’s main advantage is its combination of fast blocks and low costs for users who stake TRX or receive delegated Energy, which makes it attractive for stablecoin transfers and simple dapps. However, Ethereum remains the largest smart contract platform by total value locked and developer activity, while BNB Chain benefits from its connection to the Binance exchange ecosystem.
Frequently asked questions
Is TRON a good investment?
We do not give investment advice. TRX is a volatile asset, and its value can go up or down based on market conditions, adoption, and regulatory developments. Always do your own research and consider your risk tolerance.
Can I mine TRX?
No, TRX cannot be mined. New TRX is created as rewards for block production: currently 8 TRX per block for the Super Representative that produces it, plus 128 TRX per block shared among the top 127 candidates and their voters. Fees paid by burning TRX remove coins at the same time, so the supply can grow or shrink depending on how busy the network is.
What is the difference between TRX and TRC-20 tokens?
TRX is the native coin of the TRON blockchain. TRC-20 tokens are created on top of TRON using the TRC-20 standard, similar to how ERC-20 tokens work on Ethereum. They are separate assets but rely on TRX to pay for network resources.
