Getting mixed information.

According to https://etherscan.io/block/0) it does and was mined by 0x0000000000000000000000000000000000000000 on July 30th but according to the Parity (archival mode) it does not.

Furthermore, the first transaction in or out of 0x0000000000000000000000000000000000000000 was on August 7th, so it doesn't appear to actually have gotten the block reward.

edit: sorry, apparently mined rewards are on this view of Etherscan: https://etherscan.io/blocks?m=0x0000000000000000000000000000000000000000&p=4

So apparently it did mine it and was rewarded? Can anyone confirm and give details / sources for more information.

Block 0 wasn't mined. It was "manually" written by geth. Mining occur only when the process does pass through consensus stage, since block 0 never goes through consensus, nobody gets mining rewards. The processing of the genesis block is special and you can see it in core/genesis.go, the function is DefaultGenesisBlock()

Current versions of geth reject mining if eth.coinbase isn't set, so probably in the old days this validation was absent and miners were forgetting to set reward address.

I don't know about Etherescan, but in my own database the first value transfer to ZERO address starts from block 5305, you also can verify my data in Etherscan by querying the block number directly. Here is the list of blocks mined with ZERO address from a DB of 4M blocks (only, I don't have it up to date):

postgres=> SELECT v.block_num,b.block_hash,src.address AS source,dst.address AS destination FROM value_transfer as V LEFT JOIN block as b ON v.block_num=b.block_num LEFT JOIN account AS src ON from_id=src.account_id,account AS dst WHERE kind='4' AND to_id=dst.account_id AND dst.address='0000000000000000000000000000000000000000' ORDER BY block_num LIMIT 100;
 block_num |                            block_hash                            | source |               destination

You can't have a transaction out of ZERO address, nobody' knows it's private key, and probably it may not exist at all.

Those where value transfers, transactions to ZERO address start from block 46420 and there is about 500 of them made within first 4M blocks.

postgres=> select block_num,tx_hash from transaction where to_id=1 order by block_num limit 20;

Apparently, 0x0 didn't get the block reward, because it's balance at block 1 was 0. You can verify this:

curl -X POST --data '{"jsonrpc":"2.0","method":"eth_getBalance","params":["0x0000000000000000000000000000000000000000", "0x1"],"id":1}' https://mainnet.infura.io/yourInfuraKey

And it didn't change at Block 2 or 3 either.
