Is there a wife key, my wife is hiding something from me.

need to open her heart and find out.


Thanks. Although this is helpful, it’s still difficult for beginners to understand, and as a result, they might never join or invest. But still, good stuff.


Thanks for the diagram, now I get it ๐Ÿ˜Š


Always keep your keys safe… Crypto, car, house, all of them


This a good handy chart! Nice work!


This is all the **key** to having a successful crypto journey.

Iโ€™ll let myself out โœŒ๐Ÿฝ


House keys, car keys, key lime pie. Sooooo many keys


Loved the phone notes-made diagram ahah, still really clear thanks ๐Ÿ™‚


No man it doesn’t seem cool to me as I’m a fuckn slow learner


More keys than signs, and those are everywhere.


I can have unlimited wallets/addresses associated with just one seed phrase?


Very complex


Another great thing is the Master Public Key (xPub). This can be used to derive all your public keys (and therefore addresses), but has no critical information stored to reconstruct any of your private keys or seed phrase.

What this can be used for? Creating a watch-only wallet of your cold wallet for example, that can see all your existing and future addresses you could generate from this wallet, while the wallet remains cold, you don’t even need to connect it if you saved the xPub once.

And then there are hardened addresses that can’t be generated from the xPub key – but let’s not make things too complicated for today. Not many wallets use the hardened addresses as far as I know.


Thank you ChatGPT , very complex summary via the flow diagram.

The only thing you need to remember with keys is that you keep them secret and don’t share it with anyone, not even your wife as she could post a selfie


Someone using chatgpt


I need one key

One key to rule them all


But it’s really important to say Not Your Keys, Not Your Coins. Also, you can say that with a Car, or a House.


Nacho keys nacho crypto


Nice write up.


Depends on your wallet type on some of those too. But the key, keys are Seed (secret words), private key (password) and public key (letterbox)


Cryptographic key is a thing too.


Can i use a google tile to help find my lost keys?


Now I want key lime pie ๐Ÿฅง


I really enjoy learning about the new stuff about Crypto, so thank you for this ๐Ÿ˜Ž๐Ÿค˜


Sorry to be “that guy”, but… The number of private / public keys is not unlimited. While a 256bit integer is huge, it isn’t unlimited.

Other than that hair splitting, your summary is a good start for beginners.

I will let myself out.

Edit: Good job leveling up. Perhaps the next steps would be to look into how keys are derived (ed25519, secp256k1, etc…) between chains and also the effect of derivation paths on public key / account key / public address and how collisions between chains are avoided.


My room is locked I need a key. You have 3 keys right?


How would you generate other keys from a single seed phrase?




You forgot to mention the **derivation paths** to the keys and addresses from a seed phrase:

Depending on the cryptocurrency and wallet implementation (metamask, coinspace, etc.) you might get different wallet addresses from the same seed phrase.

This definitely confused me in the beginning, as I thought that there is only a single derivation path in ethereum. But it’s not.


It’s such a shame not a lot of people are willing to learn about crypto and just want quick money. The technology is so fun.
