Indexer
Software that scans a blockchain from a defined start point and reconstructs inscription ownership, metadata, and balances for wallets and markets.

An indexer is off-chain software that reads every relevant transaction from a blockchain (ideally from genesis or a known deployment height) and builds a queryable view of inscriptions, transfers, and token balances.
Without an indexer, raw chain data is hard for end users to interpret. Wallets and marketplaces typically depend on one or more indexers; if indexers disagree, users may see conflicting ownership or listing states.
Early Doginals infrastructure providers (for example Doge Labs, later wound down) and collection-operated stacks (including tooling associated with Doginal Dogs, which publicly describes full-chain indexing from block zero) illustrate how critical indexers are to day-to-day UX.
