Why gas exists
Blockchain networks meter computation, storage or transaction processing as scarce resources, and gas expresses that execution cost, commonly paid with a native network asset. A useful way to understand this is to connect the concept with its operating conditions and the result recorded on-chain. imtoken focuses on making network, transaction and permission details understandable before users confirm an action. The wallet interface can prepare and display an action, but the selected network ultimately records transaction state, so a clickable button is not proof that every parameter is correct.
For practical use, define the intended outcome first and then review the items related to why gas exists one by one. Confirm the network and account context, check the address, asset or requesting contract, and only then review fees, permissions and confirmation details. Separating these checks makes it easier to identify whether an unexpected result comes from the network, transaction parameters, a contract or local display state.
A helpful learning model for why gas exists is to divide an action into preparation, submission, network confirmation and follow-up review. Blockchain networks meter computation, storage or transaction processing as scarce resources, and gas expresses that execution cost, commonly paid with a native network asset. Preparation checks whether conditions match, submission checks the exact request, confirmation verifies what the network recorded, and follow-up review covers transaction history and any permissions that remain active.
- Confirm the network, account or requester related to why gas exists
- Verify the address, network and amount before a transfer; consider a small test when appropriate
- Read signature and approval details instead of treating later requests as automatically trusted
- Keep the transaction hash or other information needed to verify on-chain status
What to do when the result differs from expectations
If the interface, network state or outcome does not match what you expected, avoid repeatedly submitting the same action. Confirm the active network and account, then use the transaction hash, a suitable block explorer or contract information to establish what has already happened. For why gas exists, distinguishing a local display issue from a transaction already recorded on-chain is an important first step.
Fee changes and transaction speed
Demand, transaction complexity and fee mechanics can change actual cost; paying more does not make an incorrectly addressed or unintended transaction correct.

How a transaction hash locates a record
The hash produced after submission is a key identifier for checking whether a transaction is pending, confirmed, failed or otherwise changed in network state.

Confirmation depth and final state
After block inclusion, later blocks increase confirmation depth; what counts as sufficient confirmation depends on the network and use case.
