The chain takes ordinary spends of up to eight inputs and outputs, whose
key-path signatures may carry SIGHASH_SINGLE|ANYONECANPAY (0x83); reveals
keep their two-in, two-out shape. A new make op records an item, an
inscription its maker holds. Any node can offer test BTC for an item another
node holds, in any holding: the buyer's SegWit key signs the whole deal, the
offer stands in the lab, and the holder accepts by countersigning the item's
input, so the item and the payment swap in one transaction. Offers go stale
when a promised coin moves or a side re-keys or closes, and payments spend
unpromised coins first. Sends take up to eight coins. Mainnet is a third
mining setting: no holding mines, beats pay the lab wallet, and holdings are
funded from it. The sample ends on lineage's open offer for sol's launch-kit.
