The Zcash community account @mine Zcash tweeted that the Zcash circulation supply (9.8 million) recorded by data service providers such as CoinMarketCap, CoinGecko, Bitfly, etc. is incorrect. Since Blossom, the block production time and rewards have changed. The current supply should be 8.9 million. CoinMarketCap replied to the account in this regard, please let a formal team member submit a supply update request, because the website data is not simply obtained from the api or blog post, but has different calculation principle graphics.
