GetBlockProof()

arith_uint256 GetBlockProof

(

const CBlockIndex &

block

)

GetBlockProofEquivalentTime()

int64_t GetBlockProofEquivalentTime	(	const CBlockIndex &	to,
		const CBlockIndex &	from,
		const CBlockIndex &	tip,
		const Consensus::Params &
	)

Return the time it would take to redo the work difference between from and to, assuming the current hashrate corresponds to the difficulty at tip, in seconds.

GetSkipHeight()

static int GetSkipHeight ( int  height )

inlinestatic

Compute what height to jump back to with the CBlockIndex::pskip pointer.

InvertLowestOne()

static int InvertLowestOne ( int  n )

inlinestatic

Turn the lowest '1' bit in the binary representation of a number into a '0'.

LastCommonAncestor()

const CBlockIndex* LastCommonAncestor	(	const CBlockIndex *	pa,
		const CBlockIndex *	pb
	)

Find the last common ancestor two blocks have. Both pa and pb must be non-nullptr.
