Blockchain Glossary

Plain-language definitions for address, gas, hash, EVM, Layer 2, DApp and other common terms.

Safety principle

Never share your seed phrase, private key or verification code. Review the address, network and request details before you sign, approve or transfer.

Address, private key and seed phrase

How to evaluate it

Address, private key and seed phrase is a distinct part of understanding Blockchain Glossary. Separate interface labels from on-chain facts: an address identifies an account, the selected network determines where the asset and transaction exist, and a signature or approval can change permissions or trigger execution. The goal is not to memorize button positions. A safer habit is to identify the request, the network, the permission being granted and the result you expect before you confirm anything.

Address, private key and seed phrase is a distinct part of understanding Blockchain Glossary. Separate interface labels from on-chain facts: an address identifies an account, the selected network determines where the asset and transaction exist, and a signature or approval can change permissions or trigger execution. Fees, confirmation speed and supported features vary across networks. A wallet interface is only one view of the activity; the corresponding blockchain record remains the stronger reference for transaction status.

Gas, blocks and confirmations

Operational and risk points

Gas, blocks and confirmations is a distinct part of understanding Blockchain Glossary. Separate interface labels from on-chain facts: an address identifies an account, the selected network determines where the asset and transaction exist, and a signature or approval can change permissions or trigger execution.

Use a least-privilege mindset. Never share a seed phrase, private key or verification code, and do not lower your review standard because a request claims to be support, an airdrop, an upgrade or an urgent notice.

EVM, Layer 2 and bridges

EVM, Layer 2 and bridges is a distinct part of understanding Blockchain Glossary. Separate interface labels from on-chain facts: an address identifies an account, the selected network determines where the asset and transaction exist, and a signature or approval can change permissions or trigger execution. A repeatable sequence helps: verify the source, check the address and network, review the amount or permission, then keep the transaction hash and verify confirmation on-chain. Stop when details conflict.

DApps, signatures and approvals

Operational and risk points

DApps, signatures and approvals is a distinct part of understanding Blockchain Glossary. Separate interface labels from on-chain facts: an address identifies an account, the selected network determines where the asset and transaction exist, and a signature or approval can change permissions or trigger execution.
