# Constructor
For Standard library version 7 or 8:
BlockInfo(timestamp: Int, height: Int, baseTarget: Int, generationSignature: ByteVector, generator: Address, generatorPublicKey: ByteVector, vrf: ByteVector|Unit, rewards: List[(Address, Int)])
For Standard library version 6:
BlockInfo(timestamp: Int, height: Int, baseTarget: Int, generationSignature: ByteVector, generator: Address, generatorPublicKey: ByteVector, vrf: ByteVector|Unit)
