According to BlockBeats, on September 14, Fractal Bitcoin announced that the Fractal version of ord has been released with source code. This version is designed to help developers build specifically for Ordinals on Fractal.
The main modifications of the Fractal version of ord from the Bitcoin mainnet include: ordinal activation is set at block height 21000, rune activation is set at block height 84000, ticket name is adjusted from AZ to az, and the sats index is adjusted to reflect the difference in total supply between Fractal and Bitcoin.
All changes will take effect at block height 21000.
