Last week Casey Rodarmor released a pretty much the final version of runes protocol alongside docs. Here are some details about runes you didn’t know: 🧵

Spacers in rune names don’t matter: if there’s a rune called “ARUNE”, you can’t create a rune called “A•RUNE” or “ARU•NE”

Only 13+ charter rune names will be available right after halving.

Minting is optional, in order to distribute a rune’s supply through a mint, an etcher can set terms including supply cap and/or end of mint. This mint is free and open to anyone as long as it hasn’t ended. Alternatively, an etcher can premine all the supply to themselves and distribute it however they like.

Cenotaphs are runes that don’t fit the current structure. They are essentially an upgrade mechanism that makes a client not recognize all runes from versions newer than client’s.

Rune etchings take 6 blocks to mature, so if you want to create a new rune, you’ll need to submit a txn and wait for 6 blocks after it is confirmed. Only then it is actually created.
