About TRON Blockchain
What is TRON?
TRON is a high-throughput Layer 1 blockchain founded by Justin Sun in 2017. It was designed to support decentralized applications (DApps) and content sharing at scale, with a focus on high performance and low transaction costs. TRON has grown into one of the largest blockchain networks by transaction volume and total value locked.
Key Technical Specifications
Consensus
Delegated Proof of Stake (DPoS)
Throughput
~2,000 TPS
Block Time
3 seconds
Base Transaction Fees
Near-zero
The combination of DPoS consensus and optimized block production enables TRON to handle high transaction volumes while maintaining fast finality and minimal fees for users.
TRX: The Native Token
TRX is TRON's native cryptocurrency. It serves several critical functions in the network:
Staking: Users can stake TRX to earn rewards and participate in network security
Governance Voting: TRX holders vote to elect Super Representatives (SRs) who produce blocks
Transaction Fees: TRX is used to pay for bandwidth and energy costs when executing transactions
Base Currency: TRX serves as the primary settlement currency for on-chain activity
Token Standards
TRON supports multiple token standards:
TRC-20: Fungible tokens, analogous to ERC-20 on Ethereum. TRON is one of the largest networks for USDT transfers, with many users choosing TRC-20 USDT for its low fees and fast settlement.
TRC-721: Non-fungible tokens (NFTs) for unique digital assets
TRC-1155: Multi-token standard supporting both fungible and non-fungible assets in a single contract
Account Model
Each TRON account is identified by an address starting with the letter T. An account can:
Hold TRX and any TRC-20, TRC-721, or TRC-1155 tokens
Execute transactions and interact with smart contracts
Manage associated resources: Bandwidth and Energy
Bandwidth is consumed for basic transaction data transfer; Energy is consumed when executing smart contract operations. This resource model separates simple transfers from computationally intensive operations and enables predictable fee structures.
Smart Contracts
TRON uses the TRON Virtual Machine (TVM), which is compatible with Ethereum's EVM (Ethereum Virtual Machine). Developers can write smart contracts in Solidity and deploy them on TRON with minimal modifications. This EVM compatibility has facilitated the migration of many DeFi protocols and DApps from Ethereum to TRON.
TRON Governance
TRON's DPoS consensus is governed by:
27 Super Representatives (SRs): Elected block producers who validate transactions and produce blocks. SRs receive block rewards and voting rewards.
SR Partners: Entities that support SRs and share in rewards
SR Candidates: Nodes that compete to become Super Representatives through community voting
Token holders stake TRX to vote for their preferred SRs. Voting power is proportional to staked TRX, and the top 27 candidates by votes become Super Representatives.
Architecture Overview
The following diagram illustrates TRON's layered architecture:
TRON's Resource Model and TronZap
TRON's resource model—Bandwidth and Energy—is what makes services like TronZap possible. By staking TRX or renting resources, users can obtain the Bandwidth and Energy needed to execute transactions without paying per-transaction fees. TronZap leverages this model to provide convenient resource management for TRON users.
For a detailed explanation of how Bandwidth and Energy work, see TRON Resource Model.
