Phase 1 — Fractal Node upgrade ✅

On February 11, the Fractal Node upgrade was already activated at block height 1,500,000, which enforces the consensus mechanism change (Adjusted block reward distribution from the 1:2 (Merged Mining : Permissionless Mining) to 1:1:1 (Merged Mining : Permissionless Mining : Indexing) and enables the subsequent reward distribution change.

➡️ What's Next

Phase 2 — Lightweight Indexer Release (Expected in March)

We will develop and open-source a lightweight indexer to ensure data availability and open for anyone who might want to test the indexing and staking mechanism.

All indexing block rewards generated in Phase 1 and 2 will be temporarily held in a static address, and will be allocated entirely to rewarding testers and early participants once Phase 3 is activated

⚠️ For developers, miners, and others interested in participating in the Phase 2 lightweight indexer testing, please stay tuned and be patient. We will keep you updated as progress continues.

Phase 3 — Staking and Reward Distribution Live (2026 Q2)

The full standard indexing service goes live with staking and reward distribution activated. At this stage, all users will be able to participate in indexing staking and earn rewards.
