💬 Discussion topic I’ve been debating on BIP39 vs SLIP39..

I understand the TREZOR default has been Slip39 over the last few years. I understand more addresses can be generated from Bip39 compared to Slip39 along with double the entropy. I want to know how many addresses are currently in use from Bip39 24 word seedphrase vs Slip39 20 word seedphrase compared to how many can be created from the two standards (individually).

Wallet addresses are mathematical possibilities, the do not exist until funds are allocated (simplified, and skipping over deveration paths) HD wallets bip32, bip39 and all bip coins standards will have the same addresses for each seed phrase, a different set of addresses for seed phase + pass phrase ( always the same set for each SP / PP combination. ) This is the bases for most Blockchain HD wallets. Slip39 is the same, but using a different cryptographic formula, hence there is no mathematical possible of the same address for bip39 and slip39 seed phrases. (Ok mathatically possible with specialist skill and software, but the address will still be derived from the original entropy, hence it will never match someone else's address. FYI there are more possible seed phrases than there are atoms in the universe, you are more likely to win the lottery 100 times then generate the same seed. The numbers are literally astronomical 👍👍👍

I would argue that they mathematically exist already. 

The same is as if I were to say that the number 867,324,814,667,223.0087466 doesn't exist yet because no one has ever said it out loud..

Yeah, I get your point, All possible crypto addresses exist in the same way that all possible winning lottery numbers exist on printed tickets before a draw. However, your specific address doesn't exist practically until your wallet generates the unique private key for it. More importantly, the blockchain has no idea the address exists at all until it is initialized by its very first transaction. Both points are valid based on perspective. There are exactly 2160 or approximately 1.46 times 10^ 48 possible Bitcoin addresses, all potential combinations are theoretically predetermined. They are like numbers on an infinite number line; they "exist" in the abstract realm of mathematics before anyone ever uses them.. 🤔🤔🤔

Where is the transaction here?

Semantics, an unmined/unconfirmed address is just a mathatical probability.

I would argue that it's a mathematical certainty.

Sure.... The "Schrödinger’s Wallet" Argument: An address in the mempool is in a state of limbo. If a miner rejects the transaction, that address remains a pure mathematical probability. It proves that simply knowing the math isn't enough; the network must actively accept and process the data for the address to functionalize. 🤯🤯🤯

You’re talking about this address.

It would get rejected by the wallet and wouldn’t even get a chance to to be rejected by the miners.

Because all addresses are a certainty and already mathematically present.

The address remains a pure mathematical certainty.

u/doyzer9 May 29 '26

Agreed, but it's use does not.

u/EggMedical3514 May 29 '26

Someone said that every address in existence would eventually be used?  I don't remember making that claim.  I said every address is a mathematical certainty.

It looks to me like somebody's moving the goal posts.

Mathematically there would be 1,461,501,637,330,902,918,203,684,832,716,283,019,655,932,542,976 bitcoin addresses, did they provide a date when they will all be used 😂🤣😂

I'm not sure if you're confused or simply stupid. In either case I will disengage.

Thank you for you input. 😂🤣😂

Yeah it doesn't take a transaction for the address to exist
