Let's say a player encounters an enemy on a grid-based game, how can I generate a random number on chain to generate the enemy basic characteristics ( HP, strength, agility... ) at the time of the attack? Or the amount of a treasure contained in a chest?

According to this answer and this implementation by Asbjornenge one way is to originate a contract and use its address as a seed to get randomness, and provides entropy using Harbinger Oracle. How is this address generated and how predicatble is it?

Is there a faster/safer/better/less predictable way to get randomness on chain if the game manages a great amount of ꜩ, or should I go with Asbjornenge's implementation?

Thanks

You can use Acurast data providers to generate secure random bytes from inside a TEE(Trusted Execution Environment)

How does it work?

You schedule a job in this contract where you provide the script for generating the random bytes and a few other job configurations, like the destination contract(Your game).

Currently, the jobs can only be registered by the administrator. Let me know if you are interested, I can put you in contact with the developers.

The job will look like this: enter image description here
