Mirrors

Mirrors can be hosted using any webserver, we recommend nginx:

nginx 1.18.0+

Root www folder (usually located at /var/www/html on *nix systems) should contain snapshots packed into ZIP archive, near zip archive should be also JSON file with snapshots list and speedtest.bin/speedtest.min.bin files. For testnet new folder can be created at /var/www/html/testnet

Create folder for testnet snapshots

mkdir /var/www/html/testnet

Put all your snapshot zips in /var/www/html and /var/www/html/testnet

Create txt file with sha256 hash of each snapshot archive, format:

<sha256 hash> <archive name>

Example:

935dbf1703f7fd210aa3b5dc120b4a71a1a7983883bb22cb291530469d9632dc  20220208-veil-snapshot-1603475.zip

Create speedtest.min.bin and speedtest.bin files in all network folders

dd if=/dev/zero of=/var/www/html/speedtest.min.bin bs=51200 count=1
dd if=/dev/zero of=/var/www/html/testnet/speedtest.min.bin bs=51200 count=1
dd if=/dev/zero of=/var/www/html/speedtest.bin bs=3145728 count=1
dd if=/dev/zero of=/var/www/html/testnet/speedtest.bin bs=3145728 count=1

Create JSON configuration for snapshots

# open snapshot.json file
nano /var/www/html/snapshot.json
# put next content, remove comments
{
  "status": {
    "errorcode": "0",
    "errormsg": "ok"
  },
  "snapshots": [
    {
      "name": "20220208-veil-snapshot-1603475.zip", # name of this archive
      "sha256": "sha256sum_20220208_1603475.txt",   # name of file with sha256 hash of archive
      "block": "1603475", # latest block in snapshot
      "date": "20220208"  # date when snapshot was created
    },
    ...
  ]
}
