There are endless ways to derive entropy from existing hash algos.
for example you can do sha256("weak password 4")
this gives you
b4424dd47712534183a59c2bf448ef713ac976af320f1a14180e76b44a85e9d1
You can split that output at the 7th digit. easy to remember because you have had 7 broken bones.
b4424dd< - >47712534183a59c2bf448ef713ac976af320f1a14180e76b44a85e9d1
you can swap the parts
47712534183a59c2bf448ef713ac976af320f1a14180e76b44a85e9d1 < b4424dd
Too simple. but in order to test every common weak password, now takes 64x as long. What if you split that hash into groups of 3, and assemble them differently? What if you take half of them and produce another hash?
What if you used sha512?
With a few simple methods like these, part of your algo is secret, so an attacker can never attack it on account of having weak seed entropy such as a short password.
Take notes and practice recovering the output from time to time.
It likely improves security across the broader ecosystem for there to exist many hundreds of different seed derivation schemes.
What will save this and many other schemes from brute force adventurism, is the fact that once you use this to generate the master private/public key pair > individual key pairs > address hashes, there is no way to tell how the seed was derived.
So unless you go announcing it on the web, (too late for you) brute force attacks have to come through the hash-wall, and derive a private signing key from a matching public key.
This is not publicly know to be possible. Social engineering is where it's at: do not post on Facebook that each of your family members is memorizing 3 words for you.
Hey, can you tell whether one is able to send sats from multiple lightning channels to satisfy an order; or does it need to be a single transaction?
since argentine folks are so enamoured with governemnt, none of them will will only declare only a limited portion of their holdings to get the tax rebate, right?
What are the fees like for sending to on-chain address from muun balance?
Assuming it costs more than chain fees.
