In short
A block explorer provider is a service that reads blockchain data and presents it in a searchable form. The underlying records are facts from the chain, but labels and categorisations are added by the provider and can be wrong. For anything important, cross-checking on more than one explorer is the safer habit.
Key points
- A service that reads and displays chain data
- Transactions and balances come from the chain itself
- Address labels and tags are the provider's guesswork
- Cross-check anything important on a second explorer
Definition
A web service, and the company behind it, that collects and indexes blockchain data so transactions, addresses and blocks can be searched.
Anyone can obtain blockchain data, but running a node and turning it into something searchable takes effort. Explorer providers do that work, so you can paste a transaction hash or an address and see the state directly.
Balances and transaction histories shown are read straight from what the chain recorded. Labels such as 'this address belongs to an exchange' or 'this token looks fraudulent' are the provider's own research, and that layer can be mistaken or out of date.
Whatever you type into the search box is sent to the provider's servers, so your lookups leave a trail. It is also worth noting that a provider can be down while the chain runs normally — a page that will not load is not evidence that a transaction failed.
Watch out for
- · Labels and 'verified' badges are the provider's judgement, not a guarantee
- · Searches are logged by the provider, leaving a privacy trail
- · Fake explorers appear in search ads
