Capacity history of a specific address

[Keith-CY]

This feature comes from the community.

It would be great if the ckb balance history is available on the address page. But API is more desirable because the team proposed this request can host their own page.

There is currently no account system in the system to record account balance changes.

The only available data is the balance snapshot of the CKB address on the blockchain, but this data is periodically cleaned up. The historical balance record of the address requires cell queries, which involve extensive statistical calculations and can cause performance issues.
