Where each figure comes from, how fresh it is, and which ones we calculate from the protocol rules ourselves.
| Data | Source | Refreshed |
|---|---|---|
| Block height, supply, network difficulty, hashrate, transactions | Blockchair | Every 6 hours |
| ZEC price, market value and 24-hour change | CoinGecko | Every 6 hours |
| One-year price history | CoinGecko | Daily |
| Upgrade heights and funding rules | Zebra node source code and the ZIPs | Every 6 hours |
| Grant applications and decisions | Zcash Community Grants issues on GitHub | Every 6 hours |
| Announcements and governance threads | Zcash Community Forum | Every 6 hours |
| Wallet and node releases | Each project's public GitHub releases | Every 6 hours |
Each page shows when it was last updated. If a source is unavailable, the page keeps its last good value rather than showing a guess, and the update time tells you how old it is.
Supply and new ZEC per day are calculated from the protocol rules, not copied from a third party: the block reward schedule, the block time (75 seconds today, 25 seconds after NU7 as drafted in ZIP 218) and the funding-stream shares. As a check, our calculated supply at the current block is compared with the live supply reported by the network. Today they differ by 0.032%.
Dates of future events are estimates. We project them from the timestamp of the latest block and the expected block time. Real blocks arrive a little faster or slower, so a projected date can move by a day or more over several months.
NU7's activation height is set in the node software, and every date on the site is calculated from it.
We read every application in the Zcash Community Grants repository. Labels on those issues sometimes contradict each other, so each application is given one status, the most final one that applies: completed, withdrawn, cancelled, approved and in progress, declined, does not meet criteria, or still open.
Time to decision runs from the day an application is filed to the day its issue is closed with a decision. Progress reports are posted on the forum, so we link to each grant's thread rather than judging delivery ourselves.
