On smart-contract-enabled chains, a Full node keeps recent state; an Archive node adds all historical state from genesis. Bitcoin has no per-block historical state — chain state is the UTXO set, derived from the chain itself — so there is no separate Archive class. Chainstack Bitcoin nodes are non-pruned with
txindex enabled: every block and every transaction from genesis is queryable. Full does not mean pruned.Historical address queries (transaction history, balance at a past block) need an indexer like electrs — available as a Bitcoin Dedicated Node customization. Contact us to enable it.Method availability
