How Dark Compute works.

Batches follow the Ethereum L1 block number, which Robinhood Chain exposes to contracts as block.number. A batch is 21 blocks: 16 for commits, then 5 for reveals. Settlement is open to anyone for the 26 blocks after the batch ends; after that the batch is void and every revealed order unlocks.

commitHash = keccak256(abi.encode(
  trader, batchId, market, side, gpus, hrs, limit, salt
))
side   0 = rent (bid)   1 = provide (ask)
limit  USDG base units (6 dp) per GPU-hour

A commit pulls a 1 USDG bond from your vault. A reveal returns it and locks funds: renters lock gpus × hrs × limit plus the fee ceiling, providers lock a 20 % service bond.

1. Sort bids by limit, highest first, and asks by limit, lowest first.
2. Walk both books while the bid limit is at least the ask limit.
3. Price p = floor((b* + a*) / 2).
4. Quantity Q = min(Σ bids ≥ p, Σ asks ≤ p).
5. Orders better than the margin fill in full.
6. Filled bids and asks are paired in priority order.

A lease escrows the renter's payment and streams it linearly to the provider over the lease hours, starting when access is delivered, not at settlement. The renter can halt at any time.

0.10 % per side in USDG, capped at 0.50 %; a change waits 48 h after it is queued. Nothing is redistributed: there is no staking or rebate path in the contract.

A tier comes from DARKCOMP locked in the pool with lockDark. A lock holds for 7 days from the last lock. It pays nothing: no reward, no fee share.

• Delivery is off-chain.
• The host can see the job.
• Clock jumps can cost an unrevealed commit its bond.
• Cheap asks risk a smaller provider bond.
