Now I can generate addresses, based on seeds. There are only 2^32 possible combinations, so now I know, how exchange addresses were generated:

Code:

I also reached vanity address generator. However, it requires real Proof of Work, so it takes some effort, to mine addresses with given prefixes:

Code:

I wonder, if future versions would allow importing 32-bit seeds, and hacking into different wallets.

By the way: in the past, some people lost real coins, by using weak seeds, so your code refers to things, which really happened.

Challenge for readers: find my seed in this game: 1dZKFvMVd9B8wqezG4BdjqPceReEbAMdra (hint: it is a brainwallet, not a randomly-generated thing; but of course you can bruteforce it, if you have no clue).

Edit: I think I have a name for OP_CHECKSIG, if you will ever want to implement Script: OP_CHECKSEED. It should verify, that the transaction creator knows the seed, without revealing it explicitly, like I did. Now, I will try to explore, how seeds are picked, so maybe you could use them as public keys, and pick something else as a private key. I also wonder, how signatures should look like.

Edit:

Fun little tangent — There are "secret commands" in the console that'll do stuff in the game, but are completely impossible to decrypt from the source code.

As far as I know, there are two secret commands: one is "p2pcurrency", and another one is what we are supposed to guess. I think I know the command to the first secret, but for unknown reason, it shows just some Unicode garbage, instead of showing some meaningful message, like "p2pcurrency" does.

So, should I dig deeper, and try to write some code, to decrypt that Unicode garbage, or is it just a bug, which should be fixed?

Code:

await decrypt_aes(SECRETS[1],await sha256("p2pcurrency"))
"<comment>The Times 03/Jan/2009 Chancellor on brink of second bailout for banks<br><br>In a world where trust is a liability, consensus is power.<br>Thank you, Satoshi.</comment>"
await decrypt_aes(SECRETS[0],await sha256("p2pcurrency"))
Uncaught (in promise) DOMException: The operation failed for an operation-specific reason
await decrypt_aes(SECRETS[0],await sha256(easy_to_guess_secret))
//some unicode garbage goes here

Is it a bug, or a feature?
