What is a blockchain explorer?¶

A blockchain explorer is a service that displays publicly available data from a blockchain in a readable form.

Avoid the dangerous assumption¶

The dangerous assumption is that the explorer is the blockchain itself or that everything it displays is complete, final and automatically accurate.

An explorer may show wallet addresses, transaction hashes, amounts, tokens, fees, block numbers, timestamps and confirmation status.

It can help investigators verify that a transaction exists and follow recorded movement between addresses. It may also expose token transfers or smart-contract interactions not obvious from a wallet summary.

Different explorers may label the same information differently.

Some use local time, some use Coordinated Universal Time and some show estimated values or added address labels.

An address label such as “exchange” or “merchant” may come from the explorer’s own analysis or third-party information.

It should not be treated as definitive attribution without corroboration.

Preserve the underlying transaction hash, complete addresses, network, block number and date accessed.

Do not rely only on screenshots or bookmarks.

Web interfaces can change, labels can be updated and services can disappear.

Where evidential significance is high, record the source and consider preserving the relevant page or data through an approved method.

An explorer normally shows on-chain activity.

It may not show internal transfers within an exchange or payment provider.

It also does not identify the human user behind an address.

When reporting, distinguish blockchain data from the explorer’s presentation, labels and interpretation.

Operational takeaway¶

Use blockchain explorers to locate and inspect on-chain records, while preserving the underlying identifiers and independently verifying any labels, attribution or interpretation.
