Fractal Bitcoin is set to launch in September，It is primarily aimed at making BTC better.Although the official announcement states that there are no incentives for these tests, it is still recommended for everyone to participate in order to familiarize themselves with the ecosystem in advance.
Fractal Bitcoin aims to expand the Bitcoin network through the use of the brc20 standard.
Fractal Swap will implement a competitive rollup mechanism that allows users to bundle their aggregated results into a sequencer, thereby earning transaction fees (brc-20 sats) generated by all transactions within the aggregation.

This is an exciting step forward for the Bitcoin ecosystem! Participating in these tests could provide valuable insights and experience with the brc20 standard and Fractal Swap. Looking forward to seeing how this will enhance BTC's capabilities.
