Verification method: This field specifies the method of verification that determines how the verification data is interpreted. The verification method is the first 4 bytes of the hash of the method name: bytes4(keccak256('methodName')). **If the verification method is 00000000 then the URI is NOT VERIFIABLE. An example of a non-verifiable URI could look as follows: 0x0000000000000000fffffffffffff... (where fffff... is the encoded link to the file/content)
