**Super** **Representatives**: Special accounts in TRON that have the rights to receive citizen votes, produce blocks, and vote on proposals. Any account can apply to become a Super Representative (it costs 9999 TRX).

**FullNode**: A node that holds all data in TRON.

**SuperNode**: SuperNode is a full node deployed by Super Representatives, and private keys are passed as parameters when running. Therefore, SuperNodes are actually running the full node code.

**Wallet**: A common type of client used for interacting with blockchain; relative to the wallet, blockchain can be considered as a server.

**Blockchain Explorer**: Initially used to display blockchain data, it now also includes functions for interacting with the blockchain.

**TRX**: The token on the TRON blockchain.

**Freeze**: In the consensus implementation plan of TRON’s DPoS, freezing TRX can obtain voting rights.

**Vote**: In the consensus implementation plan of TRON’s DPoS, voting for Super Representatives.

**Staking Rewards**: Voting for Super Representatives can earn certain profits based on the proportion of votes.

**Proposal/Voting Request**: Some parameter changes in the TRON network need to be agreed upon, these parameters are packaged into a proposal; Super Representatives conducting a ballot on the proposal is known as initiating a voting request.

**Bandwidth**: A kind of resource required for any transaction to go on-chain in TRON. It can be obtained by freezing TRX.

**Energy**: A kind of resource needed to run smart contract transactions in TRON. It can be obtained by freezing TRX.

**Smart Contract**: Code written in Solidity language.

**Virtual Machine**: A module used to execute smart contracts.

**Compiler**: Compiles smart contracts into instructions opcode recognizable by the virtual machine.

**OPCODE** (Instruction Opcode): The code generated after the compiler compiles, which can be recognized and executed by the virtual machine.

**Precompiled Contract**: A method implemented in the virtual machine to implement some special features, which can be understood as functioning in the same way as OPCODE.

**Internal Transaction**: Extra transactions triggered during smart contract transactions, such as transfer transactions triggered in the smart contract transaction.

**Private Key/Public Key/Address**: Private key-public key pair, address corresponding to the public key.

**Multisignature**: A mechanism for distributing various permissions of an account. For example, a transfer transaction can be set to require signing from 2 accounts to trigger.

**RPC/HTTP Interface**: Interface exposed by the blockchain to the outside world.

There are two basic token standards on TRON:

**TRC-10 standard**: Native application tokens, like BTT etc.

**TRC-20 standard:** Smart contract standard, similar to ERC-20. Tokens designed under the TRC-20 standard run compiled on the TRON Virtual Machine (TVM) and are deployed afterwards, examples are WIN, JUST, and USDT.
