Do these sites get all address data from node through json-rpc API every time?
Or, when you show it on the site, Does the site read and show the data of the node's state file directly?
If you are operating a node, I wonder if it is possible to read the balance of addresses by block height as if reading a file rather than json-rpc API.
The current goal is to find out the balance of all addresses whose balance is changed at a specific block height... The problem is that the speed is not enough to call json-rpc every time...
