# Bitcoin Blockchain Search — Blocks, TXIDs & Addresses

> Learn how to search Bitcoin blocks, transaction IDs and public addresses, read confirmations and balance changes, and browse paginated explorer details.

Search Bitcoin mainnet block heights, hashes, transaction IDs and public addresses. Results show sources and snapshot times. Block transactions and address history are paginated. An address is not an entire wallet and pending change may be negative. Keep secrets out of search; lookups reach public data providers.
