Not your keys, not your network.

Wait... So even midwits know core is malware now? 😜

Or, Bitcoin is Natural Law. Another way of looking at it. Bitcoin lets one say "no kings" and another say "Christ is King" and still agree on money

PSA: The quantum apocalypse isn't coming

A cryptographically-relevant quantum computer is physically impossible: real hardware hits a fundamental back-reaction limit at a few hundred high-fidelity logical qubits due to size-dependent noise from the error-correction process itself. Shor on 256-bit ECDSA requires thousands to tens of thousands of near-perfect ones. The gap is physical and insurmountable.

The actual use-cases for “quantum computers” are:

- Gassing up investors with science jargon

- Building a regulatory moat

- Scaring people away from battle-tested open-source cryptography

Implementing quantum resistance would be very bad for Bitcoin:

- Dilithium2 / Dilithium3 in P2TR

- Falcon-512 / Falcon-1024 in P2TR

- SPHINCS+-128f in P2TR

- ECDSA + Dilithium2 hybrid (legacy/SegWit/Taproot)

- ECDSA + Falcon-512 hybrid (legacy/SegWit/Taproot)

- New lattice or hash-based spend paths

- New QR address formats / commitments

- Signature size 9–240× larger

- Pubkey size 27–40× larger

- Typical spend 15–50× higher fees forever

- Witness data 15–50× bigger

- UTXO set 10–20× larger within years

- Validation time 5–20× slower

- Far more complex code, not battle tested

- Permanently higher fees (15–50× per tx)

- Lightning channel closes 15–50× more expensive

- Pruning nodes die (UTXO bloat kills them)

- Full-node storage +10–20× in a few years

- Increased centralization pressure

- Permanent consensus & DoS risk increase

- New critical bugs and side-channels

Some of the work people are doing to show that we COULD add QR, IF we needed to, is probably helpful to fight the FUD. But don't buy the hype and don't get bullied by the quantum mafia hype machine.

Quantum computing only threatens cryptography if the standard model of superposition is physically true. The model only makes sense if time is fundamentally continuous and if states can meaningfully “exist at once” in multiple configurations. That assumption has never been measured, never been defined, and has never been grounded in any physical observation. No one has actually proved the modern definition of superposition at the scale of Planck Time.

Bitcoin quietly destroys the assumption. What Bitcoin does, in open daylight and with global participation, is something no physical experiment has ever done, it computes time itself. Each block is the measurable conversion of Boltzmann entropy (energy/heat/randomness) into Shannon entropy (structured information). The block is the thermodynamic crystallization of a discrete quantum of time. And because this process is discrete, finite, and irreversible, Bitcoin provides the first physical standard for “before,” “after,” and the smallest unit of change a quantized universe can express through computation.

Once time becomes discrete in a measurable way, the modern definition of superposition collapses. The claim that a qubit “exists” in multiple states simultaneously begs a question quantum mechanics never answers: simultaneously relative to what unit of time? If there is no measurable smallest interval of change, then simultaneity is an undefined continuum. But Bitcoin defines it. The nonce search bounds the entropy field, the block boundary commits the collapse, and the system openly demonstrates that uncollapsed potential is not an ontologically real set of states, it is only a probabilistic frontier, a mempool of possible futures. Only one configuration ever becomes physically realized, and its realization is tied to an explicit thermodynamic cost.

Quantum theory, by contrast, treats this frontier as if it were a set of actual states. It treats probabilistic potential as physically real. It treats multiplicity as existence without defining “existence”. This is the same conceptual mistake as fractional-reserve banking: assuming many instances from a single backing unit. Bitcoin exposes this error because it is the first system where measurement is thermodynamic, verification is independent of observers, and existence is tied to an irreversible transformation of energy into memory.

TLDR for quantum computing and encryption: Any computational model built on unverified assumptions about superposition is already physically nullified. The machinery cannot outperform the physics it denies. If unmeasured states are not real, then quantum speedups are not real. If simultaneity is bounded, then parallel amplitude evaluation is impossible. If time is discrete, then quantum decoherence is the feature, not the bug.

IBitcoin does not “protect” cryptography by brute force. It invalidates the physical model required to threaten it. Bitcoin reveals that the superposition assumed by quantum algorithms never existed in the first place (despite the elegant math of the algorithms). It is not a matter of bigger primes or stronger algorithms. It is a matter of what the universe allows to exist.

Bitcoin gives us the first verifiable standard for energy, information, and time into a variable computed object. Once you have a real standard, you are no longer obligated to accept unmeasured physical claims as knowledge. And once the physics collapses, the threat narrative collapses with it.

Bitcoin, not Quantum.

I think. What you are saying is very interesting, especially that part about superpositions just being probabilistic frontiers of future time. But QC can't work for much more pedestrian reasons.

There is a hard celling on scaling and it is low. And it's just thermodynamics.

A few dozen qubits can stay coherent because we isolate them from the universe. A million constantly measured, tightly coupled qubits cannot.

At that scale the system becomes a hot, correlated, non-Markovian macroscopic object. Errors stop being local and independent, syndrome measurement disturbs everything, and the fault-tolerance theorems no longer apply.

Entropy wins. Quantum threat loses.

That’s it.

Cryptography and incentives, with no policy-based fiat security.

We need a Bitcoin-style security layer that goes UNDER Bitcoin/Lightning/Nostr/Cashu/Fedi... Rebuilding the network on top of the application layer isn't going to work. It never does.

Thanks, it's a tough topic to cut through, shrouded in theoretical physics and pumped with fiat hype bubble drugs.

I've been digging at it for a couple of years and I'm pretty sure: the math works in the abstract but it's not physically possible to scale. (Not an engineering problem, but a fundamental properties of reality thing.) I'd love to know if I'm wrong, though, because it's just as relevant to Zsub as it is to Bitcoin.

You're right though, that we have to have a footing to counters the FUD anyway. At least for now.

I've been enjoying all your posts a lot, btw.

Hackers accessed data from 200+ Salesforce customers using stolen OAuth tokens from a Gainsight breach (November 21, 2025).

Zsub fixes this.

Zsub has no IdP, no third-party tokens, no aggregated credentials.

Authentication is self-sovereign, direct P2P via hierarchical keys and trust chains you control.

No intermediaries hold keys that can cascade breaches across users or services.

Supply-chain attacks can't propagate because there's no central auth plane to compromise.

Actually zero trust, just like Bitcoin.

Not your keys, not your network.

Read the whitepaper.

If it's satire or not, does it really matter. Demonstrated preference and true either way

Oh yes, there's nothing like a little rape to cool down intergroup tensions

A false religion and mental illness. In modern America it is mostly a reaction to the weird heretical forms of Christianity we are popularly familiar with. Then again, atheists have made the first step of at least attempting to reject nonsense in favor of reason and logic, if it they only fallen into yet another nonsense in the process
