kernel: chainparams updates for 26.x

fanquake commented at 4:19 pm on October 4, 2023: member

Update chainparams pre 26.x branch off.

Note: Remember that some variance is expected in the m_assumed_* sizes.

Closes #28572.

Consider merging #25970 first and also doing the steps there, perhaps? Can easily be deferred ’til after branch off and next release though.

Incorporated this. We haven’t changed the values since the initial merge. Updating now seems ok.

nit: Could update https://github.com/bitcoin/bitcoin/blob/master/doc/release-process.md#before-branch-off to bump the example pull to https://github.com/bitcoin/bitcoin/pull/28591, as the process now includes a new step?

ACK 100b7c9b6713aa32281077b0bed6d8daecdc20be – only checked assumevalid and minimum chain work, not header sync params.
