Model v2 assigns up to 33 points to shielded participation, 33 to fully shielded share, 20 to shielded supply and 14 to tracked reshielding. Each input percentage is multiplied by its weight; the sum is rounded to an integer from 0 to 100.
Activity uses a 30-day window and Sapling, Orchard and Ironwood transaction flags. The implementation includes shielded coinbase transactions in the shielded count, while excluding coinbase from transparent and fully shielded counts. Supply is the indexed snapshot; reshielding uses 90 days of turnstile records.
This is a ZecBlock model of observed network usage, not a cryptographic security audit or a probability that a transaction can be linked. Higher public flow counts do not establish an individual anonymity set.
The current model treats absent or unavailable turnstile inputs as zero, so a low reshielding contribution can reflect data coverage. Historical values can reflect formula changes. The score updates on the statistics job’s hourly schedule; the transaction feed updates independently.
