StampDEX builds one when your wallet has none. **Bitcoin Stamps.** Artwork stored directly in Bitcoin transactions. The image bytes live on the chain itself, so the artwork exists as long as Bitcoin does. **Confirmation.** A transaction included in a block. Each further block is another confirmation. StampDEX settles an SRC-20 order at two. **CPID.** The Counterparty asset id of a stamp. Stamps are issued as Counterparty assets, and this id is part of a stamp's identity. **Deployment.** The transaction that created an SRC-20 token: its rules, max supply, and mint limit. The deployment transaction hash identifies the token. **Dispenser.** A Counterparty vending contract. Send it the asking BTC and it dispenses the asset. Closing one has a protocol cooldown before the asset returns. **Dust output.** A small output that carries structure rather than value. SRC-20 data chunks are 330 sats each; the seller anchor is 548. **Escrow addresses.** Addresses created for one listing that hold the tokens and the buyer's payment during an SRC-20 trade. StampDEX controls their keys, server side and encrypted, for the length of that trade. **Execution mode.** How a trade is executed. `external-execution` means the trade runs at StampDEX rather than inside another Bitcoin Universe product. **Fee rate.** What a transaction pays the Bitcoin network per virtual byte, in sat/vB. It goes to miners, not to StampDEX. **Floor.** The lowest live listing price. When no listing exists there is no floor, and StampDEX says so instead of showing 0. **Index.** The service that reads the Bitcoin chain and answers questions like who holds what. See [Data provenance](/docs-stampdex/zh-cn/concepts/data-provenance/). **Mint progress.** How much of a token's max supply has been minted, as a percentage. At 100 percent, minting is over. **One-time action challenge.** A short message your wallet signs before a mutation. It names the action, your address, and a hash of the exact request, expires in five minutes, and works exactly once. **部分签名的比特币交易 (PSBT).** A 部分签名的比特币交易 (部分签名的比特币交易 (PSBT)). StampDEX builds it; your wallet reviews and signs it. Nothing moves without your signature. **Reorg.** A chain reorganisation, in which a block that was part of the chain is replaced. StampDEX re-checks trades settled in the last 24 hours against it. **Sat, sats.** The smallest Bitcoin unit. 100,000,000 sats equal 1 BTC. Listing prices here are quoted in sats per token. **服务费.** StampDEX's own fee: 1.5% per side of an SRC-20 trade with a 500 sat minimum per side, or a flat 1,500 sats on a mint, deploy, or transfer. See [Fees](/docs-stampdex/zh-cn/reference/fees/). **SIGHASH_ALL | ANYONECANPAY.** The signature type a seller uses on their listing input. It commits to that one input and to all the outputs, which is why a listing can sit on the book without locking the rest of the seller's wallet. **Source map.** The object beside every market row naming where each figure came from: `stampchain`, `stampdex`, or `none`. **SRC-20.** A token standard built on Bitcoin Stamps. Deploys, mints, and transfers are stamp transactions the index reads. **SRC-101.** A name standard in the same family, used for on-chain domain names. **Ticker.** The short name of an SRC-20 token, such as KEVIN. A ticker is not an identity. See [Asset identity](/docs-stampdex/zh-cn/concepts/asset-identity/). **Unavailable.** We could not ask the source. Different from unknown. **Unknown.** The source had no answer. Never rendered as 0. **UTXO.** An unspent output, the unit of Bitcoin ownership a transaction spends.
