The issue isnt Quantum per se, but that Bitcoin uses secp256k1 private keys, which have approximately 128-bit security against generic classical discrete-log attacks. This needs fixing.. ala BIP360 or so..

The key distinction is that 128-bit classical security doesn’t imply an immediate vulnerability. The real concern is a sufficiently powerful fault-tolerant quantum computer running Shor’s algorithm against exposed public keys. BIP360 is a step toward quantum-resistant outputs, but a complete solution requires a carefully designed post-quantum signature scheme, consensus changes, and a migration path for existing UTXOs. Security upgrades must be proactive, but also rigorously tested. 🧡

I don’t like this, it assumes what Satoshi gave us is not already quantum resistant and that a quantum computer can be defined and built by centralized laboratories. It starts with the idea that Bitcoin can/must change, so it’s fine. Bitcoin computes a quantum of time physically, which falsifies the ontology that centralized quantum computers necessarily need to operate logically. Without continuous Superpostion, it’s over for CQC. Bitcoin physically and empirically proves the logic of discrete time and discrete superposition at Planck scale. There is no resolution to the double spend (measurement) problem without a quantized block of time. Which means time MUST be quantized at Planck scale, which pushes Superpostion to a sub-Planck phenomena that occurs between the discrete boundaries of the Planck tick, approximately 1.8 x 10^43 times per second. A centralized quantum computer cannot work if Superpostion is quantized and discrete. So what is Bitcoin if it computes a quantum of time memory and proof?

Exactly👌🏽 Bitcoin is deeper than most people realize. 🧡
