Description

Create a proof that's filled with zeros.

polycli ulxly zero-proof [flags]

Usage

This command prints a proof response filled with the zero hashes for a Merkle tree. Zero hashes are the intermediate hashes computed when all leaves below a node are empty (zero-valued).

These values are helpful for:

• Debugging: Understanding how populated a tree is and identifying which leaves and siblings are empty
• Sanity checking: Verifying if a hash in a proof response is a zero hash (indicating an empty subtree) or an actual intermediate hash from real data

Example usage:

polycli ulxly zero-proof

Example output:

{
  "siblings": [
    "0x0000000000000000000000000000000000000000000000000000000000000000",
    "0xad3228b676f7d3cd4284a5443f17f1962b36e491b30a40b2405849e597ba5fb5",
    "0xb4c11951957c6f8f642c4af61cd6b24640fec6dc7fc607ee8206a99e92410d30",
    ...
  ]
}

Each sibling at index i represents the hash of an empty subtree at depth i. These are computed by recursively hashing pairs of zero hashes: hash(zero[i-1], zero[i-1]).

Flags

  -h, --help   help for zero-proof

The command also inherits flags from parent commands.

      --config string      config file (default is $HOME/.polygon-cli.yaml)
      --pretty-logs        output logs in pretty format instead of JSON (default true)
  -v, --verbosity string   log level (string or int):
                             0   - silent
                             100 - panic
                             200 - fatal
                             300 - error
                             400 - warn
                             500 - info (default)
                             600 - debug
                             700 - trace (default "info")
