The Standard
A currency you cannot inflate
The Joule-Credit is a physical commodity standard. One JC is permanently defined as one megajoule of verified energy. It is not a cryptocurrency, not a blockchain token, and not backed by any fiat currency. Its supply cannot be expanded by decree — only by the actual generation of energy. You cannot print energy. You cannot inflate a megajoule.

Fixed. Immutable. Physics-backed.

Post-quantum secure from day one.
How It Works
From fusion reactor to interstellar settlement
Step 1
Fusion Reactor Produces Energy
An SFS-certified D-T fusion reactor achieves net energy output. Telemetry systems record the megajoules produced in real time.
Step 2
3/4 Oracle Consensus
Four independent oracle nodes — the Board, the Ethics Bureau, SFS Technologies Ltd, and a rotating external auditor — must each confirm the energy measurement. Three of four must agree.
Step 3
JC Issuance
On 3/4 oracle consensus, exactly 1 JC is minted per verified megajoule. The issuance is recorded on the permissioned SFS energy ledger. It cannot be reversed.
Step 4
CRYSTALS-Kyber Encryption
All oracle communications and JC transactions are encrypted with CRYSTALS-Kyber 768 — post-quantum secure. JC is designed to remain cryptographically sound on civilisational timescales.
Step 5
Cross-System Exchange
JC can be exchanged for energy on any SFS-operated system. As orbital rings, the Dyson swarm, and interstellar stations come online, JC becomes the universal unit of account.
Step 6
Interstellar Settlement
At interstellar scale, JC settles across light-year distances via time-stamped energy certificates. The 1 JC = 1 MJ relationship holds across all SFS systems regardless of location.
The Difference
Why JC, and not anything else
Joule-Credit™
Anchored to the joule — an immutable physical constant
Supply expands only as fast as civilisation generates energy
Functions across any signal delay, including light-years
No issuing state, no central bank — Foundation-governed
Outside the scope of crypto-asset regulation by design
Built for 50,000+ year operation across many star systems
Cryptocurrency & Fiat
Crypto value is collective belief, not physical reality
Bitcoin's fixed cap makes hoarding rational, spending irrational
Real-time consensus fails across light-year delays
Fiat depends on government decree and is inflated by policy
Stablecoins inherit every weakness of the fiat they track
None were designed for multi-star, multi-century operation
The Sun is the central bank. Its policy is thermodynamics. It cannot be lobbied, captured, or persuaded to print.
