Thanks for the compliment, but to be honest i just follow the Feynman technique. Anybody can made these videos. If you do not know what the Feynman technique is, just watch th-cam.com/video/_f-qkGJBPts/w-d-xo.html
Great video as always, thanks very much Can you please put all videos on Wallet generation and key management in a playlist so they’re easy to reach? Also, can you do a video on cold storage and deriving child and grandchildren keys for hdwallets Thanks
In your wallet explanation you state public addresses are automatically derived from private keys. I thought public addresses are derived from the hash of a public key of a public/private key pair. This is how it is explained in "Inventing Bitcoin: The Technology Behind The First Truly Scarce and Decentralized Money Explained" by Yan Pritzker. Could you please clarify? Great video though!
Checkout my "Cryptocurrency address generator and validator": www.mobilefish.com/services/cryptocurrency/cryptocurrency.html and follow the steps. You can clearly see how the public address is generated.
Hi Mobilefish, how safe is it to trust a hardware wallet to generate a trustworthy 24 seed phrase ? Is it possible for someone to copy the Phrase at the manufacturing factory for later theft after the wallet has been funded by a customer? thank you!
Kev, normally a seed phrase is generated when the user creates one themselves. If you receive a hardware wallet with a pre-generated seed phrase then contact the seller immediately and DO NOT USE THIS SEED PHRASE AND WALLET! Only buy a hardware wallet from a manufacturer/seller with a GOOD reputation.
how can I get my bitcoin cash coins from electron cash which are on the watch only account as I mistakenly sent them to electrum. I have the seed and private key
Hello, please help! i forgot my bip38 passphrase for a wallet is there anything i can do to decrypt the private key passphrase. i have 0.1 bitcoin which is alot for me. any suggestions Will be greatly appreciated. Thanks.
Hello #mobilefish Im learning and developing an deterministic wallet in Javascript... So I have multiples clients (Client 1, Client2...) with multiples currencies (Client1Currencies: USD, BTC..., Client2Curriencies: USD,BTC) My question is know what is the best option to save ONLY ONE "seed" and the derivate multiples address.. so always with the MASTER seed I can restore all my coins...Can I used like this: master.derivePath("m/44'/60'/0'") clientMaster.deriveChild(0).deriveChild(CurrencyUSDID); clientMaster.deriveChild(0).deriveChild(CurrencyBTCID); or Im wrong?? Thanks for your videos..
Joining all words in the list to one string without spaces does not work. I tried the test vectors mentionend in the BIP39 standard. The correct result can only be generated with ASCII-whitespaces between the words. Also i generated two different valid mnemonic sentences which lead to the same string when the whitespace is removed: youth river unable you thrive run able tip left basket pyramid actress outside unlock enough upon real shoulder coconut flame pottery know outdoor else you thrive run able youth river unable tip left basket pyramid actress outside unlock enough upon real shoulder coconut flame pottery know outdoor else Removing whitespace results in the following string for both sentences: "youthriverunableyouthriverunabletipleftbasketpyramidactressoutsideunlockenoughuponrealshouldercoconutflamepotteryknowoutdoorelse" but if you enter them there: iancoleman.io/bip39/ they produce different BIP39 Seeds: e9da2b451d3163e860ce2fe4ba034c359bc5742e0938ea67f528765c4773396a9062f7e1b09d22a9e2d75267ca41ec68bf0684900d7b9257e69c58dc7680e7ee fd990ba19b39e4bddc84e14d69d167f2cc5fc0190cf35d36cb096f2cae418763800bf80fb176b418eb4763049bd9dd1e931231f921666ebb33f85974d09a9e9d
Ahh, now I get it. Yes it is theoretically possible but I have personally never seen this before. It all depends on the random number generator used by these tools. It is usually a pseudo random number generator (PRNG). See: th-cam.com/video/lEDQNZCwxus/w-d-xo.html It is very difficult to create a true random number generator (TRNG) as demonstrated in th-cam.com/video/1cUUfMeOijg/w-d-xo.html For a practical understanding why random generators are important, see: th-cam.com/video/6ecxIJOJ-yg/w-d-xo.html
If you have your recovery passphrase (usually contains a sequence of 12-24 words), you can always generate all your public and private keys again. There are two ways to solve this: 1) On an OTHER computer install you wallet software and enter your recovery passphrase. You can generate a new public key with corresponding private key. Keep generating the pub-priv keys until the public key matches the one with the missing private key. 2) Ask a developer to create such a tool for you. PLEASE DO NOT ASK ME!
Now that I understand BIP-39 I actually feel comfortable using it. Thanks man, great video.
God bless you for giving us this knowledge
Great video, very detailed. Everyone storing Bitcoin should understand BIP-39.
it's surprising to see how diverse and detailed your knowledge is.

Mobilefish.com Thanks for sharing. You are evidently knowledgeable and humble enough to share your secrets. I'll have a look.
Very clear and detailed, adding some little advices here and there, very good job! Keep going with those videos !
That's absolute perfection, thank you Sir!!!
Great explanation! Finally someone gets into the technical details and not the boring high level garbage!
You are a very good teacher. I really like the way you explain it. Keep it up!!!
Very well done! Thanks for sharing this video. I can say now I'm very comfortable with mnemonic words.
I really like the way how you explain complex things. Great video!
Thank you very much! Crucial information that is hard to find on the web is explained here so well!
I thought this was very informational. Thanks for explaining it so clearly!
very clear and easy to understand, thank!
How do hardware wallet restore my wallet without internet when I enter the private key?
This is the definition of gold
great explanation ! Thank you !
amazing
Good explain! thanks a lot.
nice explanation!
Great video as always, thanks very much
Can you please put all videos on Wallet generation and key management in a playlist so they’re easy to reach?
Also, can you do a video on cold storage and deriving child and grandchildren keys for hdwallets
Thanks
How many private keys are generated on a wallet's instantiation? How are more keys created when all you have is the mnemonic?
that's very useful! thank you

Sorry, but if you lose your bip39 passphrase there is no way to access your keys.

There are many private key generator is it possible to get others private key
Sorry I do not understand your question.
@@Mobilefish He is referring to the likelihood of a collision given that the generators are public, and so many people would be using them.

So a wallet should really be called a keychain?
Sir i have lost my seed how to recover on legal way
