'''Modified thresholds''' -The 1915 threshold (based on in BIP 34's 95%) does not have to be maintained for eternity, but changes should take the effect on the warning system into account.

In particular, having a lock-in threshold that is incompatible with the one used for the warning system may have long-term effects, as the warning system cannot rely on a permanently detectable condition anymore. '''Conflicting soft forks''' At some point, two mutually exclusive soft forks may be proposed. The naive way to deal with this is to never create software that implements both, but that is making a bet that at least one side is guaranteed to lose. Better would be to encode "soft fork X cannot be locked-in" as consensus rule for the conflicting soft fork - allowing software that supports both, but can never trigger conflicting changes. diff --git a/bip-0039.mediawiki b/bip-0039.mediawiki index c44ad3e..b553666 100644 --- a/bip-0039.mediawiki +++ b/bip-0039.mediawiki @@ -139,4 +139,4 @@ Haskell - https://github.com/haskoin/haskoin .NET C# (PCL) - https://github.com/NicolasDorier/NBitcoin -JavaScript - https://github.com/bitpay/bitcore-mnemonic +JavaScript - https://github.com/bitpay/bitcore-mnemonic, https://github.com/bitcoinjs/bip39 diff --git a/bip-0068.mediawiki b/bip-0068.mediawiki index 0082db3..0303924 100644 --- a/bip-0068.mediawiki +++ b/bip-0068.mediawiki @@ -49,6 +49,8 @@ The block produced time is equal to the median-time-past of its previous block.
