According to Lorenzo, the FIP-101 node upgrade for the Fractal Bitcoin network is set to activate at block height 1,500,000, introducing a new consensus mechanism and updated block reward distribution. The changes will align mining rewards among merged mining, permissionless mining, and indexing. While indexing block mining may not activate immediately, the upgrade ensures preparation for a standardized indexing system. Miners and node operators are encouraged to update to node version v0.3.0 to ensure smooth activation.

According to TRON DAO, the GreatVoyage v4.8.1 (Democritus) update is now live and is a mandatory upgrade for all TRON nodes. The update brings expanded compatibility for ARM64 and JDK 17, aligns the SELFDESTRUCT behavior with EIP-6780, and includes multiple optimizations to enhance network performance and stability. Node operators must upgrade by March 9, 2026, to avoid synchronization issues.

According to Adam Back, Bitcoin Core v30 includes security and robustness fixes, and calls to reject these updates constitute a social attack on Bitcoin.
