const CBlockHeader pblock,
const Consensus::Params params,
const CBlockIndex pindexAnchorBlock 
)
noexcept

Compute the next required proof of work using an absolutely scheduled exponentially weighted target (ASERT).

With ASERT, we define an ideal schedule for block issuance (e.g. 1 block every 600 seconds), and we calculate the difficulty based on how far the most recent block's timestamp is ahead of or behind that schedule. We set our targets (difficulty) exponentially. For every [nHalfLife] seconds ahead of or behind schedule we get, we double or halve the difficulty.

◆ ResetASERTAnchorBlockCache()

void ResetASERTAnchorBlockCache ( )
noexcept

ASERT caches a special block index for efficiency.

If block indices are freed then this needs to be called to ensure no dangling pointer when a new block tree is created. (this is temporary and will be removed after the ASERT constants are fixed)
