Nodes & consensus
Nodes & consensus is a practical part of understanding Public Chains. Learn how public chains record shared state through nodes, blocks, transactions, confirmations and explorers. Before acting, confirm that the active account, target network and intended outcome all match, then review the parameters shown in the request.
Nodes collectively maintain network state, although consensus and block-production rules differ by chain. The balances and transactions shown in a wallet ultimately come from that public state.
For Nodes & consensus, a repeatable sequence is useful: verify the source and network, check the address or contract, review the amount, permission or fee, and keep a transaction hash when one is created. This does not remove every risk, but it makes decisions easier to explain and problems easier to trace.
Practical checks
- Verify the network and account before working with nodes & consensus
- Double-check important addresses, contracts, amounts or permissions
- Never send a seed phrase, private key or verification code to anyone
Blocks & transactions
Blocks & transactions is a practical part of understanding Public Chains. Learn how public chains record shared state through nodes, blocks, transactions, confirmations and explorers. Before acting, confirm that the active account, target network and intended outcome all match, then review the parameters shown in the request.
Blocks organize transactions into an ordered history. A transaction gains more confirmations as later blocks are added, but the practical threshold for “enough” confirmations varies by network and use case.
For Blocks & transactions, a repeatable sequence is useful: verify the source and network, check the address or contract, review the amount, permission or fee, and keep a transaction hash when one is created. This does not remove every risk, but it makes decisions easier to explain and problems easier to trace.

Confirmation
Confirmation is a practical part of understanding Public Chains. Learn how public chains record shared state through nodes, blocks, transactions, confirmations and explorers. Before acting, confirm that the active account, target network and intended outcome all match, then review the parameters shown in the request.
A block explorer can query public data by address or transaction hash. It is useful for checking broadcast status, block inclusion and fees, but it does not replace confirming the recipient and network before sending.
For Confirmation, a repeatable sequence is useful: verify the source and network, check the address or contract, review the amount, permission or fee, and keep a transaction hash when one is created. This does not remove every risk, but it makes decisions easier to explain and problems easier to trace.
