Term Definitions:

Rune: A fungible token on the Bitcoin network, such as a memecoin or a utility token.

Etch: The process by which a Rune is created. Once set, the properties of a Rune are immutable.

Rune Name: A unique ticker for a Rune, consisting of 1 to 28 characters from the letters A through Z. Initially, only names with 13 or more characters are available for etching. Every three months, the character count requirement decreases by 1 until all names are available in four years.

Spacer: An optional bullet that can be added to a Rune Name during etching to enhance readability. However, the uniqueness of a name is not dependent on spacers. For example, the name "UNCOMMON•GOODS" includes a spacer.

Rune ID: A unique identifier generated for each Rune based on the block of the etch transaction and the transaction's position within the block. For instance, if a Rune was etched in the 20th transaction of the 500th block, its ID would be "500:20".

Rune Symbol: A single Unicode code point representing a Rune's currency symbol, displayed after quantities of that Rune.

Supply: Calculated as Current Mints multiplied by Mint Limit, plus the Premine.

Divisibility: Indicates how finely a Rune may be divided. For example, a Rune with a divisibility of 0 cannot be divided, while a Rune with a divisibility of 2 can be divided into hundredths (e.g., 0.01).

Mint: During an open mint, anyone can create a mint transaction to receive a fixed amount of new units of a Rune, subject to the terms of the mint.

Mint Terms: Rules determining when a mint opens or closes, such as a specific block height range or a mint cap.

Mint Limit: The fixed amount of new units of a Rune created by each mint transaction.

Mint Cap (Max mints per Rune): The maximum number of times a Rune may be minted. A mint is closed once the cap is reached.

Minting Progress: The percentage of the current number of mints relative to the mint cap.

Start Height: The block height at which a mint opens.

End Height: The block height after which a Rune may not be minted.

Premine: Optionally allocated units of the Rune to the etcher during the etching process.

Transferring: When transaction inputs contain Runes or new Runes are created through a premine or mint, these Runes are transferred to the outputs of that transaction. The transfer of input Runes to outputs may be influenced by a transaction's runestone.

Runestone: Rune protocol messages stored in the "OP_RETURN" area of a Bitcoin transaction.

Edict: A message within a Runestone that allows customization of the output destination and amount of Runes transferred during a transaction. This feature enables crafting custom transactions, such as sending Runes from one address to multiple addresses within a single transaction.

Cenotaph: If a Runestone is malformed or encounters an error, it is referred to as a Cenotaph. In the event of a Cenotaph, all Runes in the transaction are burned.

Burn: You can destroy Runes in your possession by transferring them to the "OP_RETURN" output of a Bitcoin transaction.
