2017-07-14Remove confusing MAX_BLOCK_BASE_SIZE.Gregory Maxwell
Some people keep thinking that MAX_BLOCK_BASE_SIZE is a separate size limit from the weight limit when it fact it is superfluous, and used in early tests before the witness data has been validated or just to compute worst case sizes. The size checks that use it would not behave any differently consensus wise if they were eliminated completely. Its correct value is not independently settable but is a function of the weight limit and weight formula. This patch just eliminates it and uses the scale factor as required to compute the worse case constants. It also moves the weight factor out of primitives into consensus, which is a more logical place for it.

SequenceLocks functions are used to evaluate sequence lock times or heights per BIP 68. The majority of this code is copied from maaku in #6312 Further credit: btcdrak, sipa, NicolasDorier

2015-11-03Restore MedianTimePast for locktime.Gregory Maxwell
Revert "Revert "Add rules--presently disabled--for using GetMedianTimePast as endpoint for lock-time calculations"" This reverts commit 40cd32e835092c3158175511da5193193ec54939. After careful analysis it was determined that the change was, in fact, safe and several people were suffering momentary confusion about locktime semantics.

endpoint for lock-time calculations" This reverts commit 9d55050773d57c0e12005e524f2e54d9e622c6e2. As noted by Luke-Jr, under some conditions this will accept transactions which are invalid by the network rules. This happens when the current block time is head of the median time past and a transaction's locktime is in the middle. This could be addressed by changing the rule to MAX(this_block_time, MTP+offset) but this solution and the particular offset used deserve some consideration.
2015-10-23Add rules--presently disabled--for using GetMedianTimePast as endpoint for ↵Mark Friedenbach
lock-time calculations The lock-time code currently uses CBlock::nTime as the cutoff point for time based locked transactions. This has the unfortunate outcome of creating a perverse incentive for miners to lie about the time of a block in order to collect more fees by including transactions that by wall clock determination have not yet matured. By using CBlockIndex::GetMedianTimePast from the prior block instead, the self-interested miner no longer gains from generating blocks with fraudulent timestamps. Users can compensate for this change by simply adding an hour (3600 seconds) to their time-based lock times. If enforced, this would be a soft-fork change. This commit only adds the functionality on an unexecuted code path, without changing the behaviour of Bitcoin Core.
