Mint any ECC Token
Can be invoked only in special contracts.
Converts SHELL to VMSHELL at a 1:1 ratio.
Q in the end stands for ‘quiet’ which means that if there is not enough Shell, it will not throw an exception.
If the account balance does not have the required number of tokens, the exchange will be made for the entire available amount. That is, MIN(available_tokens, want_cnt_to_convert).
Mint some VMSHELL tokens, allowed by available credit in Dapp Config for this Dapp Id
Calculate reward for BK after epoch ended.
Calculate minstake for BK epoch start.
Verify Groth16 zero-knowledge proof prepared based on JWT token and extra salt password to prove that the user owns some OpenId account (Google, Facebook, Kakao accounts etc). Takes as input the proof, related public input Poseidon hash and index of verification key.
Note: public_inputs must be prepared using POSEIDON instruction.
Calculate POSEIDON hash function. This hash function is designed for now especially for ZkLogin protocol needs. It takes as input all public ZkLogin data related to OpenId authentication (i.e. some public fields of JWT token and extra public data).
Note: There is: zkaddr = Poseidon(JWT.stable_id, JWT.iss, User salt password), where JWT.stable_id and User salt password are secrets. ephimeral_pub_key is a temporary key that will be used sign transactions (i.e. the related secret key) till Unix timestamp max_epoch (ephimeral_pub_key is embedded into JWT.nonce and JWT is a kind of TLS certificate for ephimeral_pub_key). modulus is RSA JWK public fresh modulus published by OpenId provider (the JWK is used to sign JWT tokens). iss_base_64, index_mod_4 is JWT public data describing OpenId provider. header_base_64 is JWT public data containing “kid” (key id) of JWK.
