> Should we plan for a reset of testnet?
Surprisingly, it is a very good question. However, replacing testnet3 with
testnet4, by just dropping support for the old network, should not be
called "reset", but rather "abandon". So, the question is: should we mine a
new Genesis Block, at height one, on top of the current Genesis Block from
testnet3, and trigger the biggest possible chain reorganization, where the
whole chain is reorged in a backward-compatible way?
Also I wonder, if that method of introducing testnet5, by doing it on top
of testnet4's Genesis Block is worth considering. Because then, some
planned changes, like entirely dropping the difficulty reset, could be
potentially turned from hard-fork into just a regular soft-fork, supported
by hashrate majority.
And of course, reorging everything is an edge case, that we may want to see
on any testnet first, before anyone will succeed with that on the main
network, if SHA-256 will ever be broken, and if re-hashing the whole chain
will be needed.
