Graveyard Shift update: it’s live on Esmeralda :green_circle:

The confidential payroll template is now published on the Ootle testnet, and it has paid a real night shift:

Open the shift tx and you’ll see the events Hired, Hired, PeriodOpened {period: 1} and ShiftPaid {period: 1, paychecks: 2}. No amount appears anywhere. Reading the same outputs back from the public indexer:

  • the night nurse’s key opens only her stub: 3000, “12 nights, ward 13”
  • the gravedigger’s key opens only his: 2500, “9 plots, lantern allowance”
  • the auditor’s view key reads 3000 + 2500 + 4500 treasury = 10,000 = the public budget :check_mark:

The faucet was dry, so I funded this by CPU-mining Esmeralda and burning tXTM over the burn/claim bridge. The whole deployment cost about 1.5 tTARI in fees. examples/live_esmeralda.rs in the repo builds the transactions and re-runs that check against the indexer, so anyone can reproduce it.

Caravel Burn Wallet: a private, verifiable burn wallet on the Tari Ootle

Description
The Caravel Burn Wallet is a burn wallet on the Tari Ootle that anyone can use and anyone
can verify. The Council mentioned wanting to burn the fees generated from the initial
Ootle launch, so I built a burn wallet they (or anyone) can audit and use.

  • Deposit-only and ownerless: TARI can go in, but nothing can ever come out. No owner, no
    admin key, no withdraw function.
  • The total burned is public and verifiable on chain at any time.
  • Burns can be private: nothing ties a private burn to your account, but the amount is
    still counted in the verified total.
  • Any project can integrate it to burn a portion of its fees forever. Caravel Trade
    already burns 0.3% of every trading fee through it.

So far: 13,128.73 TARI burned. There’s also a 25,000 XTM bounty for anyone who can rug the
wallet: Caravel on X: "1/ New in Caravel ⛵ We've been cooking the @tari Ootle's first burn-centred game 🎲🔥 As that progresses, here's our next ecosystem contribution: the Caravel Burn Wallet. Deposit only, never withdraw ... Not even us. Think you can rug it? Winner takes all: 10,000 $XTM 😏 https://… / X

Caravel Trade: a private peer to peer OTC platform on the Tari Ootle

Description
Caravel Trade is a peer to peer OTC platform on the Tari Ootle that lets you trade TARI
using the Ootle’s privacy features. To support it, I created a test token, Caravel USD
(cUSD), as a placeholder for a future Ootle stablecoin.

  • Place a buy or sell order for TARI, priced in cUSD.
  • Non-custodial: your funds sit in the order contract, never with Caravel. Only you (by
    cancelling) or a matching trade can release them.
  • Orders fill whole in a single transaction, and you can cancel anytime.
  • Private by default: amounts and balances stay hidden, from placing an order to getting paid. You can choose public at any step.
  • 1% fee per trade, paid in TARI: 0.7% to Caravel and 0.3% burned forever through the
    Caravel Burn Wallet (my other entry).
