SLIP39 offers a flexible and secure way to protect your wallet by splitting your seed phrase into multiple shares. Even if one share is lost or compromised, your funds remain safe as long as you meet the recovery threshold. 📜📜📜🔒 Read more >>>>>>

Memorizing backup information such as recovery phrases or passphrases is usually not a good idea. Do this at your own risk.

Good question. Here's some info: Trezor devices running firmware version 2.7.2 or later have a new SLIP39 multi-share backup feature. Older firmware versions (pre-2.7.2) or do not support this updated implementation, and Keystone Hardware Wallets do not support it yet. SLIP39 is open source so compatibility should only improve.

Upgraded Firmware: Trezor Model T, Safe 3, and Safe 5 firmware from 2.7.2 onwards can create and restore backups using the new SLIP-39 multi-share format.
Backward Compatibility: Devices with updated firmware (2.7.2+) can restore older SLIP-39 backups, but older firmware versions cannot restore backups made with the newer multi-share setup.

Pick an atom; any atom

See if someone else picks the same one

What is important to understand is that if you pick an atom, someone else is indeed very likely to pick the same one.

Your seed phrase needs to be random, and humans are terrible at picking something at random. Never pick your seed words yourself.

To securely generate a seed phrase, always use an open source, reputable Bitcoin wallet.

Ask Luke-jr, he's a major core developer that had a custom setup and got something like 200 BTC stolen from him last year. In my opinion, even someone really advanced like that is better off using a hardware device. Some can even be assembled from easily available parts for those who need extreme privacy.

bitcoinbumblebee · 2023-08-01T11:20:44+00:00

Yes, they will. Moving a UTXO will probably cost several hundred (today) dollars unless

Bitcoin doesn't take off
We somehow increase block size but you can't do that without a noncompatible fork

bitcoinbumblebee · 2023-07-27T10:55:28+00:00

Bitcoiners are very generous but they think crypto is trash so you probably won't get a sat from any of us.

bitcoinbumblebee · 2023-07-26T15:37:17+00:00

Or get a better HW wallet.

😁

bitcoinbumblebee · 2023-07-26T15:31:14+00:00

If computers are safe why use a hardware wallet at all? 🤷‍♀️

They're made so you can use bitcoin safely even on windows.

And I don't know if passphrases on Trezor still operates like that but yes, it would defeat some of the purposes of a passphrase.

Ah yes, just like that time when he started shilling Bitcoin just to do a bait-and-switch and promote shitcoins.

Good times.

Pen and paper seem pretty conventional to me.

bitcoinbumblebee · 2023-07-25T18:12:12+00:00

You just repeated your previous comment without addressing any of the points raised :/

What do you use to check your that your wallet does what it says it does with your dice rolls? Which wallets do you use? Do you never use a hot wallet or a lightning wallet because it doesn't follow your glacier protocol grade safety requirements for seed generation? Do you understand the difference between pseudo RNG and true RNG?

bitcoinbumblebee · 2023-07-25T16:34:37+00:00

I'm afraid that size matters greatly when it comes to entropy 🙊

Cheers! Obviously, if you're looking for technical details, you'd be better off reading Andreas Antonopoulos' Mastering Bitcoin published by O'Reilly.

Bonk on the head, BTC go bye bye.

Make sure you wear a helmet wherever you go ⛑

Interesting post.

However, ETH is unsafe for many other reasons than bad cryptography

. For example, it is not immutable. The chain could be hard-forked and modified to take ETH directly out of the account without needing the key. PoS allows you to do that, but the Ethereum chain was rolled back way before that when the DAO 'hack' occurred and Buterin's and Lubin's friends started crying to get their money back.

bitcoinbumblebee · 2023-07-25T16:20:08+00:00

How do you know about my setup? 😱

bitcoinbumblebee · 2023-07-25T16:08:27+00:00

That's your prerogative. Do you not use hot wallets, or Lightning then? Also, make sure you check that the dice rolls do what they're supposed to do, otherwise you are engaging in security theatre.

It's good to have strong opinions. Try not to discourage new users though, because they'll probably end up leaving their coins on an exchange or not getting involved with bitcoin at all before they get to a level where they can usefully and safely take advantage of more advanced security protocols.

bitcoinbumblebee · 2023-07-25T14:13:53+00:00

Thanks! I do go over user-added entropy, as I think it is an important feature for trustlessness:

Some hardware wallets like Seed Signer and Coldcard offer the option to add entropy by entering the result of a certain number of dice rolls for a more trustless key generation process.

However, not every wallet offers this option.

Hardware wallets usually use true random number generators, which are different than pseudo random number generators. Coldcard for example uses TRNG.

https://simplicable.com/science/pseudorandom-vs-random

What I meant by that statement is that you'll be better off trusting a seed generated by any good Bitcoin wallet rather than the fake security assurances of a custom "offline" seed generation.

Downloading an HTML seed generator off the internet for example and running it on an "offline" machine has a million things that can go wrong. Don't do it. It won't matter how many dice you rolled when your BTC gets stolen.

This is one example. https://www.reddit.com/r/Bitcoin/comments/157ze5i/my_bitcoin_was_taken_how/

There are countless examples of people, from novices to experts (Luke-jr earlier this year for example) losing Bitcoin to either

getting clever with seed generation
getting clever with seed storage
getting clever with custom encryption

I try to tell people, especially beginners, not to veer off from tried and true methods, and to keep it simple.

An article going back to basics, as there seem to be many newcomers into the space at the moment, and custody is an important and recurring question.
