Are hardware wallets sufficient? They are what all the normie crypto outlets suggest but Ledger hardware is closed source and could one day be exploited. I don't want to be bogged

use a liveusb like tails on an airgapped PC to generate a wallet, for peace of mind you can send a small amount to it then try signing an offline transaction to ensure you can send and receive funds with it. Buy a few metal backups like a cryptosteel and back up the seed phrase, store this in a safe or somewhere nobody will find it. Format the USB. Now you have a secure metal wallet

this it's basically the most secure way to spend them but all someone needs is your pin to do it, so I still wouldn't store the bulk of your savings in a hardware wallet. also first rule of crypto, DO NOT TALK ABOUT CRYPTO, or at least how much of it you have and how you store it.

Too late for that, I was dumb enough to trust even a single person and now the cat is out of the bag. Do you have any particular resources on paper wallets? I think I'm clever enough to figure it out but I'm not interested in learning how to use Linux.

>> No.21540690

>>21540515
Funds are not actually stored in the wallet. It's not like a vault with dollar bills in it.

The wallet contains your keys, the cryptographic codes to get access to the money.

Those codes can be stored on a piece of paper, just as well, made out into a nice phrase like horse battery staple.

>> No.21540877

>>21540690
Yes, I understand that the hardware wallet just provides you with a way to interface with the blockchain and use your keys to access your crypto. But you still have to generate a seed phrase that has to be physically stored somewhere, the same as a paper wallet. What I'm wondering is whether or not there is a big difference between using a hardware wallet or a paper wallet to interface with the blockchain, since even with a paper wallet you have to use open source software to sign your transactions.

here is the thing trezor has some serious pros but when ledger came out only ledger was hardened against side-channel attacks. not sure what is the situation now since years have passed.

i don't like either of them i think the default security and backup and restore protocols (the manufacturers instructions how to use them) are insanely retarded and just plain fucking bad.

while you can use them safely and securely if you do they don't actually add to your security but at least cost you money and exposure (like customer data leaks)

this!
at least do a 2/3 grpouping

basically you divide your 24 word seed into 3 columns of 8. A, B, C

then store at 3 separate locations: AB, BC, AC

better yet, use shamirs... because it's more secure with a partial exposure like 1 location compromised.

well the main difference is cracking a safe is about 3 hours of work with a hammer and a portable plasma cutter.

a hardware wallet secured by pin can be broken with a few grand in equipment and say under 9 hours with delivery.

while a good strong passphrase protected encrypted paper wallet would ruin a galactic empire financially to break into.

the liveusb is for making a paper wallet, it's a different usecase than the hardware wallet. Using a hardware wallet for cold storage is a waste of $60, because you'd just be using it as an expensive seed phrase generator

Yes but I can use your 2/3 grouping technique for the 24 word seed of a hardware wallet.

>>21541981
Physical security of seed words is the same whether using a paper wallet or storing the seed words of a hardware wallet. The physical wallet itself does represent a point of failure but theoretically you could use one Ledger / Trezor to generate as many different wallets as you want, and then grind the Ledger / Trezor into dust and buy a new one when you want to cash out.

>> No.21542350

using a trezor with a 25th passphrase/stealth wallet that is strong enough like 20+ chars is not actually bad security. you can even leave a decoy wallet protected by the pin in case you are coerced.

Ledger absolutely adds security. No one can make any transfers from your accounts without physically confirming on your Ledger device. Hackers have no way around this short of coming to your house and physically forcing you to do it.

And even then, you can create a dummy seed phrase that links to a fake wallet while your main stash stays safe.

>Yes but I can use your 2/3 grouping technique for the 24 word seed of a hardware wallet.
that's still only 3 locations of which you need 2. i got like 6 physical locations and as many digital (on multiple continents redundancy) all secured cryptographically and any one of them will give me full access.

i think my scheme is better cheaper and more resilient but you are on the right path at least.

Ahhhh! okay now I see. As long as you use open source hardware / open source software hardware wallet (Trezor) then you're paying the premium for the UI and the fact you don't need to use it on an air gapped PC (Since the hardware wallet signs the transactions internally right?)

I think I'm dumb enough that it's not worth the risk of fucking something up with a paper wallet. ( Assuming we can all agree that there is no risk of Trezor being compromised with open source hardware and software)

thing is you can fully test your protocols without making a single crypto transaction to it but you can also just try it out with like 0.0001 btc.

once you are confident you got everything right did your recovery tests and got the secure redundancy stashed away that's when you send actual money to the wallets.

i don't use seed derived wallets because they use deterministic hierarchic key generation which becomes vulnerable to quantum based attacks after the first transaction even if you only use an address once. any private key generates the entire hierarchy. a single key compromised will end you.

i use encrypted private keys on my bip38 paper wallets. i also like to dip the paper into molten paraffin to make it not only water and rot proof but pretty much everything proof (except fire).

so yeah i store encrypted private keys in the cloud. unencrypted seed would be a horribly idea.

one more thing to anyone using seed based wallets: commit 6 words to memory for fucks sake!

also let's say quantum comuters become a threat and you generated 6 wallets with the same passphrase store them together with addresses and all, after the first tx one of your pubkey is exposed a q computer can churn the private key and from that the recovery of your passphrase is trivial. compromising your remaining wallets...

like i said theoretically ou get a few hours of security with hardware wallets and safes. few hours to a day. after that all your bets are off.

with a proper paper wallet encrypted with a 20+ char passphrase you get 900 quintillion years (the universe is only 13 billion years old give or take, to comprehend how much is a quintillion year could break weaker minds) security (that much it would take for all the hashing power available on the world)
