Description
TL;DR: A speculative protocol design in which quantum states carry value and classical blockchains record issuance and supporting state.
About This Document
Jonathan Jogenfors proposes a distributed currency for a future with practical quantum computers. The design uses the quantum no-cloning theorem to prevent copying, divides value into quantum shards, and employs two blockchains while allowing local transaction verification rather than publishing every transfer. The paper analyzes anonymity and security within that proposed model.
Why Bitcoin People May Care
Despite its name, Quantum Bitcoin is not Bitcoin, a Bitcoin upgrade, or a deployed payment network. It is a research currency with different hardware requirements, trust boundaries, and ledger behavior. The paper is useful for comparing physical no-cloning with Bitcoin's economic double-spend defense, but its feasibility and security depend on speculative quantum capabilities and stated assumptions.
