Well, it's the right word. If you're going to do a hardfork by changing the timestamp definition, you're already doing a hardfork. At that point, you've already crossed the Rubicon and might as well put in any other necessary changes (e.g. to transaction locking), because it will be as much of

Good Afternoon, I am certain that as soon as we identify solutions they should be implemented. Basic life skills assert that procrastination is always a form of failure, where we could have realised and accomplished further yet we waited and in our present state could not ascertain what was

What, no. The `k` value is calculated implicitly, because there's only one value of it that could ever be valid - if `k` is 1 too small, we're 70 years too far back, and then the block will violate median of last 11. If `k` is 1 too large, we're 70 years too far in the future, then the block

Hi, BIP 42 is a code base consensus soft fork that at the time of activation does not really manifest as a fork because nobody is running any code not already applying it. Can a similar thing be done in 17 years? (I haven't really made sense of this year 2038 problem, I don't know or understand

yes but ... just for the sake of argument ... if a change such as this wraparound interpretation is made anytime in the next 5 years it'll be over a *decade after that *before any wrapped-around timestamp is legitimately mined ... and by then nobody will be running incompatible (decade old) node

Your solution seems to solve the problem of chain halting, but there are more issues. For example: if you have some time modulo 2^32, then you no longer know if timestamp zero is related to 1970 or 2106 or some higher year. Your "k" value representing in fact the most significant 32 bits of

It's well-known. Nobody really cares, because it's so far off. Not possible to do by softfork, no. It is possible to do by something that becomes a hardfork in 80 years, though, which is probably good enough. I proposed a solution, but nobody was really interested. Let's see if anyone bites

It seems that Bitcoin Core will stop working in 2038 because of assertion checking if the current time is non-negative. Also, the whole chain will halt after reaching median time 0x in 2106. More information: https://bitcointalk.org/index.php?topic=5365359.0 I wonder if that kind of
