I know that measuring shielded adoption - and the rate of increase in z2z transactions - has been an important concern for the community.
Inspired by Gareth Davies’ work in quantifying shielded adoption, and with the kind input and assistance of Gareth and Ian Miers, I have just launched zdash.info - a live dashboard for measuring shielded adoption.
Metrics for 8 separate categories of Zcash transactions can be tracked by the day, week, month, and year. All transaction data is updated hourly. In addition to transaction data, the site also supplies current network statistics as well as information on recently active accounts.
I hope the community finds zdash.info useful - I’m interested in continuing to expand the functionality and metrics in response to suggestions and feedback. In addition, am happy to share the repos to additional contributors.
