Content Keys Test Vectors

This document contains test vectors for content keys to help implementations conform to the specification.

Note: Currently, endianness is underspecified in the spec. These test vectors assume BE when converting hash to id (u256) and also BE when taking the slot (U256) and converting it to a byte array for hashing.

Content Keys Encodings

These test vectors verify the proper SSZ encoding and decoding of content keys as specified in the history and state network specs.

Content Id Derivations

Following the testing of the encoding and decoding of the keys, we also test the proper derivation of the corresponding content-id. This is given as both the hex string and corresponding raw U256 integer.
