Archive Node Checker
Historical Data Availability
Verify if your RPC endpoint supports archive requests (states older than 128 blocks). Crucial for historical analysis.
Infrastructure Tool
Advanced diagnostics module. Connect an endpoint to analyze.
Understand Archive Nodes vs Full Nodes
Archive nodes store the full blockchain state at every block, enabling historical queries. Full nodes only store the latest state, which is enough for normal validation but not for detailed historical lookups.
What is a full node?
A full node downloads and verifies every block from the genesis block but only maintains the latest state of the blockchain. It can validate transactions and provide current balances but cannot query historical states without additional indexing.
What is an archive node?
An archive node stores the complete state at every block in addition to all blocks. This allows you to query historical balances, smart contract storage at any block, and reconstruct the state of the blockchain at any point in time.
When to use archive nodes
Archive nodes are essential for explorers, analytics platforms, historical audits, and tools that require accurate queries of past states. Full nodes are sufficient for most wallets and validators that only need the latest state.
