Random number oracle by Open Solutions

Random number oracle - it is an Oracle for generating deterministic digital signatures for random numbers generation on the Waves blockchain. It includes 2 functions: sign and sendtoBlockchain

Sign($data)

Description

Signs incoming data with three RSA private keys and returns an array containing message and 3 RSA signatures.

Parameters

$rsa->setHash('sha256'); - to use a different hashing method, replace sha256 with your own

Require

• (string) $data - message for sign (tx.id)

Return

• array : array includes message and 3 RSA signs

message returns as string, sign returns as byte array

sendtoBlockchain($data)

Creates Invoke transaction with arguments and broadcast it to the blockchain

Parameters

• $wk = new WavesKit('T'); - T for Testnet, W for Mainnet
• $seed = 'your seed here'; - change your seed here on your own seed phrase
• $dApp = 'your dApp address'; - change your dApp address on your dApp address
• tx = $wk->txInvokeScript($dApp, 'dApp method', $args, $payments); - change dApp method on your @Callable function name

Require

(array) $data - result of Sign function

Return

tx.id|error

tx.id if transaction was broadcasted, error on failure
