Generating safe random numbers (VDF related)

[exander77]

Is there a way to generate safe random number securely in Chialisp?
Can this functionality be implemented based on VDF?

[exander77]

Hello, can I get some info about this. I would like to build a project which needs safe random number generation and I was waiting for the Chia as a possible platform because it has VDF.

I am looking through codes and I am not sure if I can access VDF results inside the contract code.

It depends on how you defined random. Clearly you can only write deterministic programs, so at best you'll have pseudo random numbers. The question then is what you seed them with.

@arvidn I was reading through VDF and if I understand it correctly, VDF basically generates a random number that can anybody can verify, but nobody can arrive at it sooner. It is still deterministic, but because the result of the function is delayed nobody can know it beforehand. I would like to use it inside the smart contract to evaluate an event.

Any progress on this?

[arvidn]

I don't imagine there will be any progress on this until someone makes a concrete proposal. It would be challenging, because the consensus is already set in stone, and blocks/spend bundles can be validated "in a vacuum", i.e. the clvm program can be executed and validated without knowing which block it might end up in.

Yep, I am also interested in a solution or in a solution proposal.
It would be awesome to have some similar functionality in chia like: https://chain.link/chainlink-vrf
