Etch

Etching

Runes come into existence by being etched. Etching creates a rune and sets its properties. Once set, these properties are immutable, even to its etcher.

Name

Names consist of the letters A through Z and are between one and twenty-eight characters long. For example UNCOMMONGOODS is a rune name.

Names may contain spacers, represented as bullets, to aid readability. UNCOMMONGOODS might be etched as UNCOMMON•GOODS.

The uniqueness of a name does not depend on spacers. Thus, a rune may not be etched with the same sequence of letters as an existing rune, even if it has different spacers.

Divisibility

A rune's divisibility is how finely it may be divided into its atomic units. Divisibility is expressed as the number of digits permissible after the decimal point in an amount of runes. A rune with divisibility 0 may not be divided. A unit of a rune with divisibility 1 may be divided into ten sub-units, a rune with divisibility 2 may be divided into a hundred, and so on.

Symbol

A rune's currency symbol is a single Unicode code point, for example $, ⧉, or 🧿, displayed after quantities of that rune.

101 atomic units of a rune with divisibility 2 and symbol 🧿 would be rendered as 1.01 🧿.

If a rune does not have a symbol, the generic currency sign ¤, also called a scarab, should be used.

Premine

The etcher of a rune may optionally allocate to themselves units of the rune being etched. This allocation is called a premine.

Terms

A rune may have an open mint, allowing anyone to create and allocate units of that rune for themselves. An open mint is subject to terms, which are set upon etching.

A mint is open while all terms of the mint are satisfied, and closed when any of them are not. For example, a mint may be limited to a starting height, an ending height, and a cap, and will be open between the starting height and ending height, or until the cap is reached, whichever comes first.

Cap

The number of times a rune may be minted is its cap. A mint is closed once the cap is reached.

Amount

Each mint transaction creates a fixed amount of new units of a rune.

Start Height

A mint is open starting in the block with the given start height.

End Height

A rune may not be minted in or after the block with the given end height.

Start Offset

A mint is open starting in the block whose height is equal to the start offset plus the height of the block in which the rune was etched.

End Offset

A rune may not be minted in or after the block whose height is equal to the end offset plus the height of the block in which the rune was etched.
