What Is the Typical Ratio of Reward Distribution between Miners and Validators in Proof-of-Activity?

There is no standard ratio for reward distribution between miners and validators in Proof-of-Activity; it is a parameter that is set by the developers of each specific blockchain. The ratio is chosen to balance the incentives for both miners and stakers.

For example, a higher reward for miners might encourage more hashing power on the network, while a higher reward for validators might encourage more staking and decentralization. The optimal ratio depends on the specific goals and design of the cryptocurrency.
