Meta issue ABI suggestion

[leoloco]

Is your feature request related to a problem? Please describe. Implementing complex cryptography in smart contracts is painful and error-prone. Thus, I suggest adding some cryptography features to the ABI.

Describe the solution you'd like I suggest support for the following:

• BLS signatures
• VRF (verifiable random function) verifier, based on chainlink's VRF for example
• Multiparty threshold ECDSA scheme verifier

Describe alternatives you've considered The logic of suggested functions could be implemented as a smart contract or smart contract lib. But it is great to have a built-in standardized option.

We need exact algorithm variants, can you investigate ?

@leoloco is it still relevant ?

[leoloco]

It is not needed at the moment, so it is irrelevant
