Let's say, that 20 years ahead, Bitcoins crypto is not considered secure anymore. More precisely the key length is to short for it to be safe. Be it the HASH or private/public key. What would our options be?
Could we simply increase the keylength for the wallets and make it mandatory? Would that be a hard fork?
Or could we just use a soft fork and advise users to switch to a new more secure wallet?

1 Answer 1


This would be a hard fork, and a difficult one to develop at that.

  • Thank you! But I am right in thinking, that this would be the only way to ensure that Bitcoin would stay secure in that case, right?
