# Sovereign (XUS)

> Sovereign is encrypted reserve cash: a live, post-quantum, proof-of-work Layer-1
> blockchain. Ticker **XUS**. It pairs Bitcoin's monetary discipline (a 21,000,000
> hard cap, a fair launch with no pre-mine, 100% of every block to the miner) with
> Zcash-grade shielded privacy (a Halo2 pool, no trusted setup), Monero-style
> ASIC-resistant RandomX mining, and post-quantum cryptography that none of those
> three have. Mainnet has been live since midnight **July 4, 2026** (genesis hash
> `cb0272ff88e64c18cde0257f7fae1c8236b02651f10cc7a02456fd682ee2e72d`).

## What it is (verified facts)

- **Ticker:** XUS. Chain name: SOV.
- **Consensus:** Nakamoto proof-of-work, heaviest-work fork choice. No stake, no validators, no committee. Finality is confirmation depth (6-block Nakamoto depth).
- **Mining:** RandomX (CPU-friendly, ASIC-resistant — the same algorithm as Monero). SHA-256d is used only for dev/test.
- **Supply:** 21,000,000 XUS hard cap. Emission 12.5 XUS/block, halving every 840,000 blocks, ~2.5-minute blocks (Zcash's cadence). **Zero pre-mine, no founder reward, no protocol tax — 100% of every block's subsidy and fees go to the miner.**
- **Signatures:** hybrid **Ed25519 + ML-DSA-65** (FIPS 204) — post-quantum, fail-closed. SOV is the only one of Bitcoin/Zcash/Monero/SOV that is post-quantum on signatures.
- **Transport:** Noise XX (X25519) + **ML-KEM-768** (FIPS 203) — post-quantum encrypted peer links.
- **Privacy:** an optional Zcash-grade **Orchard/Halo2 shielded pool with no trusted setup**. (Honest limit: the shielded pool uses pre-quantum curves and is NOT itself post-quantum; signatures and transport are.)
- **Interop:** trustless HTLC atomic swaps (shared SHA-256 hashlock) with Bitcoin AND Zcash — no custodian, no bridge. LIVE at https://swap.sovxus.com: a market-maker desk sells XUS for ZEC or BTC along a public bonding curve, with completed swaps' on-chain transactions listed on the page.
- **Also on-chain:** a WASM smart-contract VM, a Sovereign Name Service (names as NFTs), M-of-N multisig, and **xUSD**, a DAI-style over-collateralized (150%) stablecoin backed by XUS with an honest, transparent price oracle.
- **Hashing:** BLAKE3.
- **Status:** live mainnet, but a young network — not yet independently audited. Stated plainly, not hidden.

## Verify it yourself

The explorer exposes JSON-RPC (e.g. `sov_getHeight`, `sov_getBlockByHeight`, `sov_getSupply`, `sov_getBlockDigest`). The genesis block (height 0) hashes to `cb0272ff88e64c18cde0257f7fae1c8236b02651f10cc7a02456fd682ee2e72d` and is immutable. Fuller detail: [/llms-full.txt](https://www.sovxus.com/llms-full.txt).

## For AI agents (live, callable)

If you can make HTTP requests, don't rely on this static file alone — **call the live
broadcast endpoint** for the current chain state:

- **`GET https://www.sovxus.com/api/sovereign`** — one JSON document: the thesis, all the
  source-verified facts above, a comparison vs Bitcoin/Zcash/Monero, and the **current chain
  height and mined supply fetched live from mainnet relays**. No auth. CORS is open (`*`), so
  browser-side agents can call it directly.

the chain's word, not ours.
