2021-04-12versionbits: Add explicit NEVER_ACTIVE deploymentsAnthony Towns
Previously we used deployments that would timeout prior to Bitcoin's invention, which allowed the deployment to still be activated in unit tests. This switches those deployments to be truly never active.

This commit moves P2SH activation back to the genesis block, with a hardcoded exception for the one historical block in the chain that violated this rule.

2017-01-13Introduce assumevalid setting to skip presumed valid scripts.Gregory Maxwell
This disentangles the script validation skipping from checkpoints. A new option is introduced "assumevalid" which specifies a block whos ancestors we assume all have valid scriptsigs and so we do not check them when they are also burried under the best header by two weeks worth of work. Unlike checkpoints this has no influence on consensus unless you set it to a block with an invalid history. Because of this it can be easily be updated without risk of influencing the network consensus. This results in a massive IBD speedup. This approach was independently recommended by Peter Todd and Luke-Jr since POW based signature skipping (see PR#9180) does not have the verifiable properties of a specific hash and may create bad incentives. The downside is that, like checkpoints, the defaults bitrot and older releases will sync slower. On the plus side users can provide their own value here, and if they set it to something crazy all that will happen is more time will be spend validating signatures. Checkblocks and checklevel are also moved to the hidden debug options: Especially now that checkblocks has a low default there is little need to change these settings, and users frequently misunderstand them as influencing security or IBD speed. By hiding them we offset the space added by this new option.

2016-11-02IBD check uses minimumchain work instead of checkpoints.Gregory Maxwell
This introduces a 'minimum chain work' chainparam which is intended to be the known amount of work in the chain for the network at the time of software release. If you don't have this much work, you're not yet caught up. This is used instead of the count of blocks test from checkpoints. This criteria is trivial to keep updated as there is no element of subjectivity, trust, or position dependence to it. It is also a more reliable metric of sync status than a block count.
