Dear decentralized node operators:

We recommend updating block_mined_polling_interval_sec to 5 in qsp-protocol-node/blob/develop/resources/config.yaml#L71

Recently we noticed some rate-limiting on requests that results in throttling for some nodes. Updating polling interval to 5 would solve the rate limiting issue, thanks!
