If an upcoming arduous fork entails a change to new methodology for key-pair/deal with era, how precisely is it going to be carried out? How would all of the outdated addresses going to alter to ones which might be appropriate with the brand new algorithm and the way is the switch of possession going to be performed precisely?
For the blockchain to maintain the identical state after the fork, there must be a brand new deal with for every outdated (incompatible) deal with that holds the identical quantity of BTC and has the identical proprietor.
A technique I can consider is including assist for each the outdated and new key-pair/deal with era strategies briefly, after which immediate all homeowners holding addresses generated utilizing the outdated methodology to ship their BTC to new addresses generated utilizing the newer methodology, and at last dropping assist for the outdated methodology. With ~30 million distinctive BTC addresses as of at present, and a present block dimension able to processing 2-7 transactions per second, this transition would wish between 50-173 days to finish, throughout which the blockchain is totally incapacitated, and miner charges being larger than common. I suppose it may additionally entice any BTC that hasn’t been transferred to a brand new deal with by homeowners in a well timed method throughout the outdated, incompatible deal with.
