Definitionen der Begriffe, die in der Dokumentation und der Benutzeroberfläche verwendet werden.

UTXO
Unspent Transaction Output. The elementary unit of a Bitcoin balance: an amount of sats locked by a script. Every transaction consumes one or more UTXOs and creates new ones.
PSBT
Partially Signed Bitcoin Transaction (BIP 174). Standard format to build a transaction, sign it in multiple steps, or hand it off to a wallet for signing.
P2TR
Pay-to-Taproot. Modern address type (bc1p…), used by default for ordinals. Dust limit: 330 sats.
P2WPKH
Pay-to-Witness-Public-Key-Hash. Native SegWit address (bc1q…), used for payments. Dust limit: 546 sats.
Sat (satoshi)
Smallest Bitcoin unit: 1 BTC = 100,000,000 sats. Every sat carries a unique serial number (ordinal).
Sat-range
Contiguous interval of sats within a UTXO, identified by [start, end). Ordiscan provides the full sat-range for every UTXO.
FIFO (First-In First-Out)
Ordinals convention: sats leave a transaction in the order they entered it. Bitcoin Tools enforces FIFO 1:1 to preserve sat identity.
Rare sat
A sat with a notable ordinal property: rarity (uncommon, rare, epic, legendary, mythic) or badge (palindrome, alpha, omega, block9, vintage, etc.).
Satribute
Modern synonym for “badge”: an additional property a sat may carry (e.g. uniform, prime, sequence palindrome…).
Inscription
Arbitrary data (image, text, JSON…) inscribed on a sat via the Ordinals protocol. Identified by its inscription ID (txid + index).
Padding
“Free” sats surrounding an inscription inside its UTXO. Can be recovered via Padding Recovery without touching the inscription.
Dust limit
Minimum amount an output must hold to be relayed. 330 sats on P2TR, 546 sats on P2WPKH. Below that, nodes reject the transaction.
Rune
Native Bitcoin fungible token standard (Casey Rodarmor, 2024). Transfers use a special OP_RETURN called a runestone.
Runestone
OP_RETURN encoding a rune operation (mint, transfer, etch). Contains edicts describing which amounts go to which outputs.
Edict
Single instruction inside a runestone: “transfer X units of rune R to output N”.
Cenotaph
Invalid or non-parseable runestone. Any rune involved is permanently burned. Bitcoin Tools refuses to sign a PSBT producing a cenotaph.
BRC-20
Fungible token standard based on JSON inscriptions. Three operations: deploy, mint, transfer.
BRC-20 locked / transferable
UTXO holding a BRC-20 “transfer” inscription ready to be sent. Bitcoin Tools locks these UTXOs: moving them consumes the transfer.
Alkane
Family of executable Bitcoin assets (meta-layer). Bitcoin Tools excludes UTXOs positively detected as Alkanes-bearing from the tools that can't handle them safely. Detection relies on an external provider; when it is unavailable, the interface reports the check as incomplete instead of claiming the UTXO is Alkanes-free.
RBF (Replace-By-Fee)
Replacing an unconfirmed transaction with another one paying a higher fee (BIP 125 opt-in signalling, or full-RBF on nodes that enable it). Relay and mining of the replacement depend on each node's and miner's policy — acceptance is never guaranteed.
Speed Up
Bitcoin Tools feature based on RBF: rebroadcasts your pending tx with a higher fee rate, funded by shrinking the CHANGE output or, if needed, by adding verified-clean Payment UTXOs as extra inputs. Recipient outputs are unchanged.
Cancel (RBF)
Bitcoin Tools feature that replaces a pending tx with a 1-in / 1-out RBF tx returning the funds to your own payment address — effectively aborts the transfer as long as the original has not been mined. Ordinals inputs of the original are never touched.
ORD badge
Orange badge shown on a transaction input or output whose address/script is Taproot (P2TR), the family used for Ordinals. It is an address-family indicator, not proof that the address belongs to you.
PAY badge
Blue badge shown on a transaction input or output whose address/script belongs to the validated payment family (Native SegWit, or a supported validated Nested SegWit form). It is an address-family indicator, not proof of ownership.
CHANGE badge
Blue badge shown on the output that returns the remainder of a transaction to your Payment wallet. It replaces the PAY badge on that output; inputs are never labelled CHANGE. Addresses that cannot be classified are shown with a neutral badge.
Ancestor cap
Bitcoin limit of 25 unconfirmed ancestor transactions per tx. Forces the Splitter and the Runes Minter to batch.
Batch signing
Ability for a wallet to sign multiple PSBTs in a single user action (signPsbts method). Today: Xverse only.
Commit / Reveal
Two-transaction scheme for inscriptions: commit prepares a dedicated taproot UTXO, reveal inscribes the content into it.
Delegate inscription
An inscription whose content points to another inscription. Lets you re-reference content without re-posting it.
Mintability
For a rune: current mint conditions (window open, remaining supply, amount per mint). Checked by the Runes Minter before each batch.
Verified-common
UTXO manually flagged by the user as “confirmed empty of rare content”. Lets it be used as payment despite an unknown status.
