ZecHub Dashboard

Here.

Intro

Finding accurate information on shielded supply is suprisingly difficult. Here is a Bash script that, when combined with the power of a Zcash Full node, can yield what we are looking for. Should note this project started after I wanted an easy way to extract info for myself here. The automation this script provides helps ZecHub's Dashboard really come to life!

Note: most blockchain explorers are wrong! You must verify!

Pre Reqs

• linux
• sudo apt install python3-github
• a zcashd node

How it works

From a high level this is what we will do:

• Extract latest node Data from a synced zcashd
• Download newest dashboard Data already on ZecHub.xyz
• Append freshly extracted node Data to downloaded dashboard Data
• Upload new dashboard Data to github in a format ZecHub.xyz likes

How to run

• chmod +x extractSupplyInfoZecHub.sh
• ./extractSupplyInfoZecHub.sh

note: If you need to use an alias (optional) do so like follows:

Myalias="/home/canakit/zcash-cli -datadir=/media/portableHD/.zcash/" ./extractSupplyInfoZecHub.sh $Myalias
