In the modern world, technology is progressing very quickly and one day there may come a moment when the reliability of a 24-word seed phrase will not be enough (it looks like the eternal fight between a shield and a sword). Is it possible to solve this problem by increasing the number of words to 36 or 48?
Yes, increasing the number of words generally increases its security. Rather, larger entropy will be encoded into more words.
It's as simple as: the higher the entropy, the higher its security: 2^256 (
24 words minus checksum) is stronger than 2^128 (
12 words minus checksum).
But 2^128 is currently secure enough.
Was it originally possible to choose a 12 and 24 word bitcoin wallet seed-phrase as it is now, or did the ability to choose 24 words come later? That is, a kind of option: reliable and more reliable. If the seed-phrase was expanded to 24 words later, what was the reason for this? What reason prompted? If anyone is aware of those events.
In
BIP39 standard, it's always been possible to generate 24word seed phrase ever since it's proposed.
But the option in different wallets/client to generate 12 or 24 words by default depends on their own implementation of BIP39.
They can go higher than 24 if they decided to do so.
For non-BIP39 wallets, it also differs per wallet since it's their own implementation of "
seed phrase"; for that, research each wallet's history.
