What Are Energy and Bandwidth in the Tron Network?
On the Tron Network blockchain, token transaction fees depend on two system resources.
If a wallet does not have enough of them, the network deducts the fee in TRX. If the resources are available, no TRX is spent.
- Energy
- for smart contracts
- Bandwidth
- for data written to the block
What Is Bandwidth
Bandwidth is consumed by almost every transaction on the Tron Network and pays for the amount of data written to the blockchain.
Every activated address receives a small daily allocation of free Bandwidth. That is usually enough for a few simple operations, such as a TRX transfer.
What Is Energy
Energy is required to execute smart contracts. A standard TRX transfer does not need Energy, but a USDT transfer does because it runs through a TRC-20 contract.
During the transfer, the network checks balances, executes contract code, and updates sender and recipient data. Energy is consumed by these computations.
What to keep in mind
If a wallet was just created or has never held TRC-20 tokens before, the first such transfer may require a double fee. That is how Tron Network works.
