What's new in v2.0.0
Three things to know about the v2 release.
Hardened proof format
The round-proof envelope now signs the full game context (game_id, round, ruleset, rng_seed, timestamp, players, state) — not just the player coins. Any tampering with envelope metadata invalidates the proof. v1 proofs are no longer accepted.
Production-quality polish
Atomic writes everywhere (no half-written save files), structured logging for operators, --json output mode on diagnostic commands, and supply-chain attestation on released binaries.
Beginner-friendlier
Install in 30 seconds with pipx install sovereignty-game, walk through the rules in 60 seconds with sov tutorial, and share scenario codes with friends.

What makes it different
Reputation that you say out loud, not jargon you have to learn. Three mechanics carry the whole game.
Promises you say out loud
Say "I promise..." at the table. Keep it: +1 reputation. Break it: -2 reputation. No app reminders — the table holds you to it.
Treaties with real stakes
Put your coins where your mouth is. Binding agreements with escrowed stakes — promises with teeth, judged by the room.
Proofs anyone can verify
Every round produces a SHA-256 fingerprint. Optionally anchor it on the XRPL Testnet — a public wall nobody can erase.
Pick your depth
Three tiers. Start at Campfire on game night one — add complexity only when the table is ready.

Skip this on game night one. When you're curious how cryptographic proof works, the console can anchor each round to a public ledger — for free, with play-money tokens.
Wallet
Create a free XRPL Testnet wallet. Test XRP has no value — it's play money.
Anchor
Post your round proof hash to the ledger. Think of it as writing the score on a wall nobody can erase.
Verify
Anyone can check the proof against the on-chain record. Trust but verify.
