Types
Chainstack supports 2 types of nodes for public chains: elastic node and dedicated node. Elastic nodes are available for all networks by default. To get a dedicated node, you’ll have to contact us directly.Modes
For most of the available public chains, Chainstack supports deploying nodes in the following modes:- Full — a node that stores full blockchain data. However, it has limitations to how many blocks are available for querying.
- Archive — a node that stores full blockchain data and an archive of historical states, which makes it possible to query any block since the chain genesis.
- Trader — a node that propagates transactions to the global mempool at high speed. See Trader nodes.
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.
