+
+This section outlines the fundamentals of and operations for Optimism.
+
+Deploying an Optimism node with Chainstack provides you with a near-instantly fully synchronized Optimism node.

+
+# Debug and trace APIs
+
+A dedicated Optimism full or archive node has the `debug_*` API methods enabled. For the full list of the available debug and trace API methods, see [Debug namespace](https://geth.ethereum.org/docs/rpc/ns-debug).
+
+## Usage examples
+
+You can debug and trace transactions by replaying them in the Ethereum Virtual Machine to get the execution details in the exact same way as they happened on the chain.
+
+Note that to debug and trace transactions, you need to have historical states on the node. Optimism full nodes keep historical states for the immediately previous 128 blocks. Optimism archive nodes keep historical states for the entire chain.
+
+### debug_traceBlockByNumber
+
+Trace all transactions included in a block with [debug_traceBlockByNumber](https://geth.ethereum.org/docs/rpc/ns-debug#debug_traceblockbynumber):
+
+``` sh
+curl -H "Content-Type: application/json" -d '{"id": 1, "method": "debug_traceBlockByNumber", "params": ["BLOCK_NUMBER", {"tracer": "callTracer"}]}' ENDPOINT
+```
+
+where
+
+* BLOCK_NUMBER — the number of the block in hex to get the traces of included transactions.
+* ENDPOINT — your node HTTPS endpoint.
+
+See [View node access and credentials](/platform/view-node-access-and-credentials).
+
+For example, trace all smart contract interactions in block 21972089:
+
+``` sh
+curl -H "Content-Type: application/json" -d '{"id": 1, "method": "debug_traceBlockByNumber", "params": ["0x14F4479", {"tracer": "callTracer"}]}' https://nd-123-456-789.p2pify.com/3c6e0b8a9c15224a8228b9a98ca1531d

+
+# Modes
+
+Chainstack supports deploying an Optimism node on the mainnet in the following modes:
+
+* Full node — a node that stores full blockchain data.
+* Archive node — a node that stores full blockchain data and an archive of historical states.
+
+To be a part of the Optimism mainnet, you can deploy either a full node or an archive node.
+
+With a full node, you can query the historical state of the Optimism mainnet at only the latest 128 blocks.
+
+To be able to query the historical state of the Optimism mainnet at any block, you need an archive node.
+
+See [Geth JSON-RPC methods](https://eth.wiki/json-rpc/API#the-default-block-parameter) that support querying at a block number.
+
+Query example to get the balance of an address at different block numbers through an archive node:
+
+``` js
+> eth.getBalance("0x06908fdbe4a6af2be010fe3709893fb2715d61a6","latest")
+187186839646605076
