sovereignty-game 2.2.1

A strategy game about governance, trust, and trade — offline tabletop + XRPL online verification.

日本語 | 中文 | Español | Français | हिन्दी | Português (BR)

A board game about trust, trade, and keeping your word.

Sit down with 2-4 friends, roll a die, move around a board, and try to end up with more coins or more goodwill than anyone else. Make promises out loud — keep them and people trust you, break them and they don't. No prior games like this needed. No screens at the table.

Play tonight

Print the whole print-and-play package — board, player mats, quick reference, and three decks of cards on 11 sheets of US Letter paper. Find a die and some coins. Sit down with two or three friends. You're playing in twenty minutes.

If you want individual sheets:

• Board — the 16-space Campfire loop, one page.
• Player mat — coins, reputation, upgrades, promises. One per player.
• Quick reference — board spaces, turn order, promise rules.
• Event cards — 20 cards, three pages, cut along the lines.
• Deal cards — 10 cards, two pages.
• Voucher cards — 10 IOUs between players, two pages.
• Treaty quick reference — Tier 3 only.

The PDFs are vector with embedded fonts — they print clean on any home printer. Setup walkthrough lives at Print & Play.

Want a console to keep score?

Optional. The game runs fine on paper. But if someone has a laptop handy, sov tracks coins, rep, promises, and produces a tamper-proof receipt at the end:

pip install sovereignty-game
sov play campfire_v1

sov play campfire_v1 is the no-config quickstart — one human plus a default opponent. For multi-player at the table, use sov new -p Alice -p Bob -p Carol. For a guided 60-second walkthrough, use sov tutorial.

No Python? The npx path downloads a prebuilt binary:

A real session

Once you and 2-3 friends are at the table, the console runs the round and you do the talking. A real session looks like this:

# Start a game with three players
sov new -p Alice -p Bob -p Carol

# Each player takes a turn — roll, land, resolve
sov turn

# Check where everyone stands
sov status

# When everyone has gone, close the round
sov end-round

sov status shows a Rich-formatted table with player coins, rep, upgrades, position, and goal. For a quick one-line glance between turns:

sov status --brief

R3 |  Alice: 7c 4r 0u | >Bob: 4c 3r 0u |  Carol: 6c 5r 0u

(Nc Nr Nu = coins / rep / upgrades; > marks the active player.)

Repeat for 15 rounds. sov game-end prints the final scores.

• Multiple saved games (v2.1+): sov games lists saves; sov resume <game-id> switches between them.
• Batched anchoring (v2.1+): sov anchor at game-end batches all pending rounds into a single XRPL transaction — one verifiable chain pointer per game. Use sov anchor --checkpoint for mid-game flush.
• Network selection (v2.1+): sov anchor --network testnet|mainnet|devnet (or SOV_XRPL_NETWORK env var; default testnet).
• Daemon mode (v2.1+, optional): sov daemon start runs a localhost HTTP/JSON server for desktop integration and background chain polling. See Daemon mode below.
• Audit Viewer desktop app (v2.1+, optional): npm --prefix app run tauri dev. See Desktop app below.

The console keeps score. You keep your word.

Daemon mode (optional, v2.1+)

For desktop integration (Audit Viewer, Tauri shell) or background chain polling, run sovereignty as a localhost HTTP daemon:

pip install 'sovereignty-game[daemon]'
sov daemon start --readonly        # audit-only, no wallet seed
sov daemon start                   # full daemon with anchor endpoints (loads XRPL_SEED)
sov daemon status                  # running | stale | none
sov daemon stop

Daemon binds to 127.0.0.1 on a random port; connection details (port + bearer token) live in .sov/daemon.json. One daemon per project root. See docs/v2.1-daemon-ipc.md for the full IPC contract.

Desktop app (optional, v2.1+)

The Audit Viewer is the v2.1 desktop app — a Tauri shell (Rust + webview) that runs the audit viewer and a read-only game view on top of the daemon.

Install (binaries)

v2.1.0 ships pre-built binaries on the GitHub Releases page:

• macOS (universal): sovereignty-app-2.1.0-darwin-universal.dmg — Intel + Apple Silicon
• Windows (x64): sovereignty-app-2.1.0-win-x64.msi
• Linux (x64, .deb): sovereignty-app-2.1.0-linux-x64.deb — Debian / Ubuntu / derivatives. Install with sudo dpkg -i sovereignty-app-2.1.0-linux-x64.deb. AppImage support deferred to v2.2 (upstream linuxdeploy / Ubuntu 24.04 FUSE interaction).

You also need the Python daemon backing the app: pip install 'sovereignty-game[daemon]'==2.1.0.

First-launch warning is expected. macOS will say "unidentified developer" — control-click the .app, choose Open, confirm. Windows SmartScreen will say "unrecognized publisher" — click "More info" then "Run anyway." Both warnings reflect that v2.1 ships with build-provenance attestation only (verify with gh attestation verify), not OS-level code signing. Workspace-level signing infrastructure ships in v2.2.

Verify provenance

Every release artifact carries a SLSA build-provenance attestation. Verify before running:

gh attestation verify \
  --repo mcp-tool-shop-org/sovereignty \
  ./sovereignty-app-2.1.0-darwin-universal.dmg

A clean verification proves the binary was built from a specific commit, by the release workflow, in this repo. Different layer of trust than OS-level code signing — the binary still triggers the OS warning, but its supply-chain provenance is cryptographically pinned.

Run from source

If you'd rather build from source (or the binary won't run on your platform):

# 1. Install Python + daemon deps
pip install -e '.[xrpl,daemon]'

# 2. Install frontend + Rust deps (one-time)
cd app && npm install && cd ..
cargo build --manifest-path app/src-tauri/Cargo.toml

# 3. Start the dev shell (auto-starts the daemon in readonly mode)
npm --prefix app run tauri dev

The Tauri shell auto-starts a readonly daemon on launch and auto-stops it on exit. Externally-started daemons (sov daemon start) stay alive across shell restarts.

See docs/v2.1-tauri-shell.md for the full contract.

Audit Viewer — XRPL-anchored proofs verifiable per round.

Game Shell — passive real-time display of the active game.

Settings — daemon network selection and configuration.

The Audit Viewer ships with three views:

• /audit — XRPL-anchored proof viewer. Collapsible per-game list, per-round anchor status, "Verify all rounds" runs local proof recompute + chain lookup in series. The auditor's view: confirm a game ran honestly without reading raw JSON.
• /game — passive real-time state display for the active game. Player resource cards, round timeline, last-20 SSE events log. Read-only; play in the CLI in another terminal.
• /settings — daemon config display + network switcher (testnet / mainnet / devnet) with mainnet-confirmation guardrail.

Full view spec at docs/v2.1-views.md.

How it works

You start with 5 coins and 3 reputation. Roll a die, move around a 16-space board, and land on spaces that give you choices: trade, help someone, take a risk, or draw a card.

20 Event cards read like moments: "Has anyone seen a small leather pouch?" (Lost Wallet) or "Nobody saw... right?" (Found a Shortcut). Includes market-shift events for Town Hall games.

10 Deal cards + 10 Voucher cards force conversation: "Spot me 2 coins? I'll pay 3 back." or "I've got your back if you've got mine." Deals set goals with deadlines; Vouchers are IOUs you issue to other players.

The Promise rule: Once per round, say "I promise..." out loud and commit to something. Keep it: +1 reputation. Break it: -2 reputation. The table decides.

The Apology: Once per game, if you broke a promise, publicly apologize. Pay 1 coin to who you wronged, regain +1 reputation.

Pick your goal (secret or public):

• Prosperity — reach 20 coins
• Beloved — reach 10 reputation
• Builder — complete 4 upgrades

After 15 rounds, highest combined score wins.

What is Diary Mode?

Every round, the console can produce a proof — a fingerprint of the game state. If anyone changes the score, the fingerprint won't match.

Optionally, that fingerprint can be posted to the XRPL Testnet — a public ledger. Think of it as writing the score on a wall that nobody can erase.

sov end-round                        # generate proof
sov wallet                           # create testnet wallet (free)
sov anchor                           # post hash to XRPL (optional)
sov verify proof.json --tx <txid>    # trust but verify

Only the host needs a wallet. Nobody else touches a screen. The game works perfectly without anchoring — it's just the diary that remembers.

Three tiers

Tier	Name	Status	What it adds
1	Campfire	Playable	Coins, reputation, promises, IOUs
2	Town Hall	Playable	Shared market, resource scarcity
3	Treaty Table	Playable	Treaties with stakes — promises with teeth

Core rules are stable through v1.x. See roadmap.

Scenario packs

Zero new rules. Just vibes. Each pack sets a tier, recipe, and mood.

Scenario	Tier	Best for
Cozy Night	Campfire / Market Day	First game, mixed groups
Market Panic	Town Hall	Economy drama
Promises Matter	Campfire	Trust and commitment
Treaty Night	Treaty Table	High-stakes agreements

Design principle

"Teach through consequences, not terminology."

Players learn by doing: issuing IOUs, breaking promises, trading at shifting prices. The concepts map to Web3 primitives — wallets, tokens, trust lines — but players don't need to know that to have fun.

Contributing

The easiest way to contribute is to add a card. No engine knowledge needed — just a name, a description, and some flavor text.

Security

Wallet seeds, game state, and proof files — what to share and what not to. No telemetry, no analytics, no phone-home. The only optional network call is XRPL Testnet anchoring.

See SECURITY.md.

Threat Model

Threat	Mitigation
Seed leakage via proofs	Proofs contain hashes only, never seeds
Seed in git	.sov/ gitignored; sov wallet warns
Game state manipulation	Round proofs envelope_hash covers game_id, round, ruleset, rng_seed, timestamp_utc, players, and state. sov verify detects tampering across the full envelope. Proof format v1 is no longer supported in v2.0.0+.
XRPL anchor spoofing	Proof hash anchored on-chain; mismatch detection in verify
Player name privacy	Player names ARE included in proofs (top-level players list and inside player snapshots). For private play, do not publish proof.json or share postcards.
