Protocol milestones

Runes protocol timeline
WhenMilestone
2023Runes proposed by Casey Rodarmor as a UTXO-native alternative to account-based token schemes on Bitcoin.
Block 840,000, April 2024Activation, at the fourth halving. Etchings before this height are not indexed. Name unlocking begins: only names of 13 letters and longer are available.
Every 17,500 blocks after activationThe minimum name length steps down by one letter, interpolating between thresholds.
Block 1,050,000All names unlock, down to single letters. The hardcoded genesis rune UNCOMMON•GOODS also closes its mint window at this height.

The consensus rules described in the specification have been stable since activation. Cenotaphs exist so that future changes can be introduced without misleading clients built against the current rules: see R46.
