abstract var diffBits: Long

abstract val hash: Hash256

Return this block's hash. Uses a cached value if one exists. If you change the block be sure to call calcHash() or invalidateHash() to update this value either greedily or lazily respectively

abstract fun BCHdeserialize(stream: BCHserialized): BCHserialized

abstract fun BCHserialize(format: SerializationType = SerializationType.UNKNOWN): BCHserialized

abstract fun calcHash(): Hash256

Force recalculation of hash. To access the hash just use #hash, to force recalc call "changed()"

Link copied to clipboard
abstract fun changed()

Communicate that this object has been changed, so recalculation of cached data is needed

abstract fun validate(cs: ChainSelector): Boolean

run checks (such as verifying POW claim) & return true if the block header is consistent
