| Zcash - fetch-params.sh | |
| This script will fetch the Zcash zkSNARK parameters and verify their | |
| integrity with sha256sum. | |
| If they already exist locally, it will exit now and do nothing else. | |
| The complete parameters are currently just under 1.7GB in size, so plan | |
| accordingly for your bandwidth constraints. If the Sprout parameters are | |
| already present the additional Sapling parameters required are just under | |
| 800MB in size. If the files are already present and have the correct | |
| sha256sum, no networking is used. | |
