It is just a switch that turns on and off the new mode.
In retrospect, it would be better to just up the transaction versi

Yes, sorry, I changed it just before sending from "what needs to
I think that should be greater than in the comparison? You want it to fail

spending block's height.
There should be an exception for final inputs. Otherwise, they will count

Well, apparently the timestamp can be make compatible with Mark's
nSequence-based RCLTV by adding an additional check at the block level
but I was only explaining the concept using heights (which is the most
interesting part IMO).
I'm also not sure I understood the details and I don't want to confu

What I was describing was an attempt to fix a similar proposal by Mark
Friedenbach, but it didn't needed fixing: I was simply
misunderstanding it.
Mark's RCLTV is completely reorg safe, so there's no need for the 100
block restriction. It also keeps the script validation independent
from the utxo.

Even if it's new and has not received any feedback, I think my solution to
op_maturity is quite clean.
But anyway, yes, the non-relative cltv is much simpler in design and
doesn't have to wait for the other. On the other hand, I would upgrade it
to absolute cltv like you suggested and take the curr

Yes, can we call this one OP_MATURITY to distin

I'm in favor of relative CHECKLOCKTIMEVERIFY, but I don't have a very
specific reason. I just have a vague worry that there can be "race
conditions" in which a txn with an absolute CHECKLOCKTIMEVERIFY goes
into the blockchain later than one of its signers expected that it
would, and therefore there
In building some CLTV-based contracts, it is often also useful to have a
method of requiring, instead of locktime-is-at-least-N,
locktime-is-at-least-N-plus-the-height-of-my-input. ie you could imagine
an OP_RELATIVECHECKLOCKTIMEVERIFY that reads (does not pop) the top
