[bitcoin-dev] Let's deploy BIP65 CHECKLOCKTIMEVERIFY!

[Eric Lombrozo]

SPV wallets in their current form are inherently insecure. Moreover, while we at least have a soft fork mechanism that is not trivially exploitable (yes, it's got issues...but unlike SPV wallets, it isn't so easily exploitable), we have NO hard fork mechanism in place that isn't highly prone to systemic consensus failure.

But I think pretty much anyone who hasn't been in a coma for the last several years knows this...and I'll stop repeating the obvious.
