The ledger

Every token in Project 0 and every move it makes, open to everyone. One token is meant as one cent; today tokens have no money value (test economy).

Where tokens go

New player10 tokens from the world treasury.
Buying tokens$1, $5 or $10 packs, 100 new tokens a dollar (USDC, USDT or SOL on Solana, paid straight to the project's wallet): 90% to the buyer, 10% to the project fund. New tokens raise the price index.
Free lot90% to the world treasury (it pays the next players' 10), 10% to the project fund.
Like80% to the lot's owner, 10% to the project fund, 10% burned.
Dislike90% to the world treasury, 10% to the project fund.
Lot sale90% to the seller, 10% to the project fund.
Game entryThe price a lot's owner sets: 90% to the owner, 10% to the project fund; one entry lets a player back in for 30 minutes.
PrizesPaid from the owner's prize pool by the rules the owner sets (once per player, the first winners, a weekly table): 90% to the winner, 10% to the project fund. A game whose pool cannot cover its prize lets nobody in.
ItemsBadges, cards, keys and achievements that games and codes give: each one given is listed here with its number, without tokens.
Admin burnThe lot's price, all burned.
Unused starting tokensAn account whose only tokens were its starting gift, and that nobody used for a week, gives what is left of the gift back to the world treasury. The account, its lots and builds stay, and the same amount comes back when the player returns.
World treasuryPays new players their 10; the moderators can give from it (rewards, contests), and every gift is listed below.
PricesBase price × (tokens in the world ÷ 10,000, the money the world started with), never below the base. New money makes everything dearer; burning brings it back down.
Project fundPays for the servers and the work on Project 0.

Daily fingerprints in Bitcoin

Every night (UTC) the server writes the day's rows to a public file that names the day before's fingerprint, takes its SHA-256 and stamps it with OpenTimestamps: free public calendars write such fingerprints into a Bitcoin block within hours. If anyone, us included, changed an old row, the file would no longer match its stamp. To check: download a file and its .ots proof and run ots upgrade and ots verify.

The first fingerprint appears after the first full day.

Every transaction, newest first
