Blockchain basics

What a transaction hash tells you

A transaction hash is a public identifier for a blockchain transaction. It can help you inspect a record, but it does not reveal every fact about the people or circumstances behind it.

What you can inspect

Depending on the network, a block explorer may show the transaction hash, block number, timestamp, sender and recipient addresses, amount, fees, confirmation status, and token transfers.

What confirmations mean

Confirmations indicate that additional blocks have been added after the block containing the transaction. Different networks and applications use different practical thresholds for considering a transaction final.

What a hash cannot do

A hash is not a password and it is not a recovery credential. It cannot be used to reverse a confirmed transaction. If an exchange account or hosted wallet is involved, account-specific questions should be handled through that provider's verified official support channel.

Safety reminder: Never share a seed phrase, private key, password, or one-time authentication code with someone who contacts you about a crypto transaction.
