This update strengthens the incentive not to confirm double-spends after
time T (30 seconds). To grow and stabilize adoption, it is necessary to
influence the miner of the block after a deprecated block, who in turn
is concerned with the block after that. Accordingly, the disincentive is
changed from a simple delay to a temporary chain work penalty, which can
be negative. Hal Finney first suggested this in 2011.
The penalty is graduated in two steps based on the respend gap, for
reasons explained within. I believe it is the minimum required to
achieve the intended result.
