I know that Monero uses hashes of the blocks as keys for the RandomX algorithm, but is RandomX less ASIC resistent if we choose a predefined sequence of key, e.g. the hash of the block height: SHA256(block_height % 2048)?RandomX docs say we could use it, but I'm wondering if there are any downsides: "To achieve ASIC resistance, the key K must change and must not be miner-selectable. We recommend to use blockchain data as the key in a similar way to the Monero example above. If blockchain data cannot be used for some reason, use a predefined sequence of keys."Thanks.
