The Fractal Bitcoin network announced the successful activation of the FIP-101 node upgrade at block height 1,500,000, completing the first phase of consensus changes and initiating the construction of a standardized index. This upgrade received support from major mining pools such as Foundry, AntPool, ViaBTC, F2Pool, and Binance Pool, covering approximately 85% of the Bitcoin network's hashrate. The Fractal block structure will gradually transition from a 1:2 ratio of syndicated mining to independent mining to a 1:1:1 three-element structure of syndicated mining, independent mining, and index block production. Index nodes will be incorporated into the core layer of the block production and incentive system.
