2021-03-22BIP8: fix typo: 2 retarget intervals are 4032 blocks.Jonas Nick
2021-03-22BIP8: remove redundant and conflicting sentence from param selectionJonas Nick
At the end of the param selection section it's explicitly stated that startheight _must_ be a multiple of 2016.

BIP8: allow some MUST_SIGNAL blocks to not signal

BIP8: Make signalling during LOCKED_IN recommended rather than mandatory
2020-10-17BIP8: allow some MUST_SIGNAL blocks to not signalAnthony Towns
Using the same threshold for MUST_SIGNAL as STARTED means that any chain that would have resulted in activation with lockinontimeout=false will also result in activation with lockinontimeout=true (and vice-versa). This reduces the ways in which a consensus split can occur, and avoids a way in which miners could attempt to discourage users from setting lockinontimeout=true.

2020-10-17BIP8: clarify timeoutheight behaviour and requirementsAnthony Towns
When lockinontimeout is true, we don't transition directly from STARTED to LOCKED_IN, so don't imply that we do. If startheight or timeoutheight are not on a retarget boundary, they behave as if they had been rounded up to the next retarget boundary, so to keep things simple, require them to be at a boundary. If timeoutheight is less than two retarget periods later than startheight, behaviour when lockinontimeout is true (one retarget period of STARTED, one of MUST_SIGNAL, one of LOCKED_IN, then ACTIVE) will not match behaviour when lockinontimeout is false (one retarget period of STARTED, then either LOCKED_IN or FAILED), so disallow that as well.

2020-10-15BIP8: replace FAILING with MUST_SIGNALAnthony Towns
This removes the FAILING state and adds compulsory signalling during a new MUST_SIGNAL phase during the last retarget period prior to the timeout height. This ensures that if a deployment occurs using bip8 with lockinontimeout=false and timeoutheight=N, that a later deployment using bip8 with lockinontimeout=true and timeoutheight=K, where K<N that any chain where LOCKED_IN is reached prior to height K, will be accepted as valid by nodes using either set of deployment parameters. It also ensures that the soft-fork's changed rules are only enforced on chain a retarget period after signalling indicates enforcement is expected (which was not previously the case if the FAILING to ACTIVE transition took place).

2017-04-21Further simplify BIP8.shaolinfry
There is no material change to the specification However, lockinontimeout is just an implementation detail, if not set the workflow is BIP9. As a result, BIP8 is more concisely represented in the simplified state.
