How nodes maintain shared state
When working through “How nodes maintain shared state”, separate what the interface displays from what the blockchain records. A wallet can organize information, prepare a request and show the result, but the selected network ultimately determines transaction and contract state. For Public Chains, confirm the network, account and destination rather than relying only on familiar buttons or visual cues.
A practical review sequence is source, target, permission and outcome. Identify where the request came from, what address or contract it affects, what authority it is asking for, and what may happen after approval. This turns a vague sense that a request “looks normal” into a set of facts that can be checked before acting.
If the interface does not match expectations, avoid immediately repeating the action. Check the selected network, whether a transaction hash exists, whether an explorer shows the record, and whether the token or contract address matches the intended asset. Confirmation can take time, especially when a network is congested.
Security boundaries remain important throughout Public Chains. imtoken will never ask for a seed phrase, private key or verification code. Do not send those secrets to anyone or enter them into an unfamiliar website. Before a transfer, signature or approval, review the address, network, amount, spender and permission scope. Third-party DApps and smart contracts can introduce risks outside a wallet’s control.
The goal is not to memorize every term. It is to build a repeatable method for checking context before acting, then verifying the result afterward.
Key point
Public chains are maintained by distributed nodes that agree on blocks and transaction state. Confirmations, transaction hashes and block height are different ways of observing that public state.

Practical checklist
- Verify the domain or source before connecting.
- Confirm the intended network and account.
- Never share a seed phrase, private key or verification code.
- Review amount, gas, signer, spender and permission scope when relevant.
- Use a transaction hash or block explorer to verify on-chain state.
