ROADMAP / HEIGHTS CONTROL
The roadmap is written in block heights.
Blackcoin Protocol V4's trajectory is a scheduled consensus program, not a list of promises with dates. The milestones below activate at fixed block heights — until an activation height passes, no divergence exists. These values are authoritative in /api/chain-params; the detailed transition timeline is on the migration page.
Scheduled consensus milestones
- #5,945,000Whitelist snapshot — Balances ≥ 10,000 BLK are snapshotted for Gold Rush eligibility.
- #5,950,000Protocol V4 + Gold Rush start — The V4 accounting overlay and the Gold Rush shadow-claim phase activate.
- #5,993,200Competing-claim rule — The first scheduled consensus divergence: conflicting Gold Rush claims are resolved.
- #6,192,999Gold Rush final block — The last block of the Gold Rush accounting phase.
- #6,193,000Migration start — Legacy outputs begin migrating to the Protocol V4 model; phase-locked credit reconciles.
- #6,921,999Migration final block — The last block of the Migration window.
- #6,922,000Legacy path lockout — The legacy elliptic-curve spend path closes; decide migratetoquantum support before this height.
Track live progress toward each height on the observatory and migration timeline. Heights — never dates — govern every boundary.
Development & governance
- Active development: tracked in the open on the issue tracker — open issues are the live work queue. (Per-release roadmap threads are closed out once that release ships, so they are history rather than a forward plan.)
- Source of truth: consensus rules ship in the signed-source daemon — the v30.1.3 release record, verifiable per the reproduction contract.
- Contract changes: API/schema changes for integrators are logged on the changelog.
