Highlights

Upgrade Handler

A new v2.2.0 upgrade handler has been added.

At the upgrade height, the network performs a full recalculation of referral statuses for all accounts based on the updated requirements.

Updated Referral Status Requirements

Self-stake thresholds for all statuses have been significantly increased:

Status	Before	After
Starter	100	1,000
Leader	250	10,000
Guru	600	25,000
Boss	1,500	60,000
Pro	4,000	130,000
Top	10,000	200,000
Mega	30,000	350,000

All other parameters (team volume, criteria count) remain unchanged.

Status Recalculation Logic

The migration logic is implemented in x/referral/keeper/upgrade_v220.go:

• Downgrade scheduling
  If an account no longer meets the requirements, a downgrade is scheduled in 7 days
  (with a 1-second interval between accounts to avoid collisions).

• Downgrade cancellation
  If requirements are met, any scheduled downgrade is cancelled.

• Automatic promotion
  If an account qualifies for a higher status, it is promoted automatically.

Build Improvements

• Added new build-all-ff target in Makefile
  (compatible with Ubuntu Focal / golang:1.21-bullseye)
