Step
A store of value must be scarce, which makes it volatile.
A spending currency must be stable, which requires expansion.
Xcoin holds. Lumero moves.
When the same coin saves and spends, save-side volatility spills directly into the spend-side. Drawdowns become unspendable.
Pegging to a fiat currency surrenders monetary sovereignty. A "digital dollar" is still the Federal Reserve's policy choice.
Reflexive mint-on-demand designs (Terra, UST) collapse under stress. Backing must be hard, not derived from the asset itself.
ECDSA over secp256k1 will eventually break. Post-quantum signatures must be foundational, not retrofitted onto exposed addresses.
Four regional stratum endpoints — Virginia, Mumbai, California, São Paulo. PPLNS port 3333, solo port 7777.
ECDSA accepted for legacy UTXOs in transition; new addresses default to ML-DSA-65 (FIPS 204) post-quantum-only.
100 XAT per block in Era 1, halving on Bitcoin's discipline. 1 satoshi-equivalent = 10-8 XAT.
Bitaxe, NerdMiner, MacMetalMiner (native Apple Silicon GPU), Antminer, Whatsminer. Every standard SHA-256 ASIC works.
nex1z (witness v2). Bech32m encoding. Forward-secure: PQ-only addresses stay safe even if ECDSA breaks.
20,000,000 XAT across 9 published allocations. Source-traceable, no hidden tranche, no foundation discretion.
25-block window with 2× clamp, activated at block 1322. Smart Emergency Difficulty Adjustment fires when solve time exceeds 600s.
XAT is the reserve: scarce, mineable, post-quantum, designed to hold value across decades. UMX is the velocity layer: elastic, basket-guided, designed to move — backed by XAT in the reserve pool at 1.5× coverage.
Hard money for the reserve.
Elastic instrument for the spend.
Constitutional governance over both.
