It's really just a seed splitting scheme, so has the same issues relating to fragility unless you make redundant backups. (And is also dependant on your remembering that you used this process) Coinkite are the only ones promoting it, so it would also be a pain to securely restore in the future if you are primarily concerned with long term HODL.
Thoughts on EAL secure JavaCards such as the SatoChip SeedKeeper to store seed-phrases / pass-phrases on, compared to something like metal storage for seed-phrases + password manager for pass-phrase?
Hah, I should have watched all the way through before commenting :) A lot comes down to what you perceive the biggest risk to be - someone taking your keys or you losing them.
Yea it really depends. I think that having a physical backup is very worthwhile, but Javacards are also an excellent way to store some redundant copies (you can also just post them anywhere on the world), especially if they are held by other people or you are traveling with them.
Would it be stupid to store the output descriptors on 'samsung bar' USBs (because they are water/ heat resistant) encrypted by exporting from sparrow? What are the best practices for backing up the output descriptor basically?
Great video, you always say the BIP39 12 words has poor checksun and we must use 24 words, in contrast the Electrum Wallet don´t use BIP39 but 12 words with version using 4 bits and 132 bits of entropy. Is the Electrum Wallet 12 words secure as 24 words BIP29?
Electrum seeds aren't BIP39 and have a different (and stronger) checksum approach that is fine for 12 word seeds :) (Not quite as strong as BIP39 @ 24w, but much better than BIP39 @ 12w
So for general joe should i use 20 word or 24 word seed phrase? i got new trezor. i have bo experience. just tell which is better for future. i will use that for holding only.
It really comes down to how you plan to store your seed and whether you are worried about physical security of the seed backup itself. SLIP39 isn't well supported by other hardware vendors, but is well supported in a range of software options, so vendor lock-in is much less of an issue than with other more proprietary options.
Thank you for your efforts Why does running 'btcrecover.test.test_seeds -v OpenCL_Tests' return ok, but running the seedrecovery command throws this error? I tried on multiple instances and with different combinations. Context failed: OUT_OF_HOST_MEMORY File "/usr/lib/python3.8/multiprocessing/util.py", line 452, in spawnv_passfds BlockingIOError: [Errno 11] Resource temporarily
As usual, great video, every newcommer should watch it once! About compatibility, bip39 only apply to BTC and eth right? Each vendor do their own ''sauce'' to derive priv key for the other type of coins
Thanks :) They generally follow standard, but the standards themselves, particularly with Ledger where development of the apps for each coin/chain is often done by the dev community for that coin. That did, standards are often a disaster for less mainstream altcoins. (Cardano is a good example of a standards dumpster fire)
As always, great content - thanks! Can you share your thoughts on Sharded Secret Key Reconstruction (SSKR)? If I understand it correctly, SSKR would allow you to spit an existing BIP39 Mnemonic into multi-share Mnemonics (like SLIP39).
The main challenge is lack of hardware and software support... The Lethekit is now unsupported, the CLI tool is in beta and who knows how long the iPhone app will last...
@@CryptoGuide Thanks for looking into this, much appreciated. I think that the method itself is excellent since it adds multi-share functionality to a BIP39 mnemonic seed phrase. I also struggle finding a proper implementation and agree with you that risk of no support in due time limits implementation. I don't like the iPhone implementation as I don't want to type a seed phrase on an online device, even though it's supposed to work when the phone is not connected to the internet. It would be nice to have an implementation like Ian Coleman's BIP39 tool, which can be used offline and kept on a memory disk for future use.
It means that you can have a typo like having two of the words swapped, or repeating a word, and still have a 1/16 chance that your wallet software/hardware will accept the seed as valid. (When compared to a proper 24 word seed where it is only a 1/256 chance that a typo like that would still be valid)
I am new to this and thus have a basic question. Once i use my 20 word recovery seed to recover my wallet to say Electrum which i understand is a Hot Wallet should i change the recovery seed given it was used online ? Do you have any best practice.
The best practice is that once you enter a seed into a hot wallet then that seed is hot forever from that point onwards... If you want one that remains totally cold then you will probably want to generate a new seed on your hardware wallet and move the funds over.
I came across your TH-cam channel when I was researching for a contest I'm trying to win, I wanted to know If it is possible to get the key phrases of a metamask wallet using the softwares on your channel. The sponser of this competition will provide us with a single key phrase each day in correct order and whoever that is in competition manages to connect to wallet can withdraw all the money plus the sponser of this competition allowed use of bots and scripts. What videos in your playlist should I watch to achieve this. And do you have recommendation for me as to with how many key phrases I should start the recovery procedjures? Thanks in advance for your time.
@@CryptoGuide Thank you, Can you please recommend a Video or a playlist from your channel? forgive me, I'm a bit lost finding the correct tutorial that would help me achieve this task.
Bro.. I had coinbase wallet extension on Chrome and my PC crashed but I retrieve the appdata file ..I copied it to new pc now it's telling me my password is wrong.. there must be some error. I know password is correct. Do you have a way for me to get my seeds
a 24 word BIP-39 seed phrase attached with a passphrase isn't enough for any size of portfolio? Messing up and over-complicating things can be also dangerous to lose access.
Depends on what you are trying to achieve, I think that passphrase+seed is fine for most people unless you are storing more than $1,000,000 USD. (Below that I think the risk added by extra complexity simply isn't worth it)

You can store them digitally, but just make sure you have redundancy there. You can often also print out a physical copy with things like sparrow.

You probably just have too many threads, try reducing it down to something more sensible like 2 per GPU...
