"Bitcoin Parity Address" , Amateur Idea

[newsecurity1986]

I don't know much about this, it's just an idea, I'm not aware that it already exists or there are better options( experts, don't humiliate me)

I made this concept of a new address double signature.

use the P2PKH addresses only to globalize the understanding of the image and it does not necessarily have to be that way.

From my point of view these wallets would be 6 times more secure than P2PKH (referring to brute force)

What do you think?

You can do such things on Taproot, just make some 2-of-2 multisig Taproot address and use Schnorr signatures (also you can use any N-of-N, but start with N=2). You can start from test networks, do that on regtest, show that on testnet3 or signet (or do that with a friend to make sure it works in multiparty scenario), and then use on mainnet after testing and making sure that it works. For now, it is not yet present in Bitcoin Core, but I think it could be included in future releases. I also expect that Lightning Network will move from HTLC to PTLC, then you will see Lightning Network channels shared by two people on a single address with a single Schnorr signature for both of them).

One question. Your diagram (which by the way should not be hosted on Reddit so it doesn't get deleted forever - try Imgur instead) says "secret exponent" next to the final SHA256. Is the SHA256 the secret exponent, or is it taken to the power of a very large unknown number?

thanks, I have modified the post, as for the "secret exponent" it is the sha256 of the "parity".

It doesn't matter that much, because if there are two people and they want to make a shared address, then it could be 2-of-2 multisig, 1-of-2 multisig or 0-of-2 multisig. Each of that three cases could be handled by Taproot.

2-of-2 multisig: PTLC as it will be in the Lightning Network.
1-of-2 multisig: Spend by key for the more likely path and spend by TapScript for the less likely. Or spend by single key with some commitment (that could be hidden in a signature), just to know who moved the coins.
0-of-2 multisig: No keys, so just a commitment that anyone can produce (and even attach to someone else, just to reduce costs).

thanks for the suggestions, I'm studying all this to see its feasibility

Don't think of it in terms of addresses and hashes, the better way is to think of it in terms of public keys and signature/key aggregation. Which is what could happen easily using Schnorr signatures introduced in Taproot soft fork.
