I would like to promote the following feature in bitcoin core:
./bitcoind -walletseed
or
./bitcoin-cli -walletseed
or
./bitcoin-qt -walletseed
where
Why? I think, that it is too little, to have HD-wallets introduced only for getting rid of the 100 keypair limit!
What people are using bitcoin core? Not the guys from the street! It is used by the more experienced people. And those know about the limit.
With this feature, one could generate its own seeds via some USEFUL method, e.g. throwing a dice and transforming the result to some integer. I am serious! Some method that is suitable for long term archiving, because the resulting string is more readable and can be carved in stone. I don't want to carve a hex number in stone, even though this is the lesser problem. And I don't want to use second hand software to reproduce the keypairs.
To further stress this: Modern storage media are NOT an alternative!!! And I won't mess around with the bitcoin core source code, even though, it seems to be a no-brainer to add this functionallity.
Please add this simple feature to bitcoin core.
