Did you know that the #Monero genesis block contains a hidden message in the coinbase field? https://xmrchain.net/block/0 https://moneroblocks.info/block/0 Look for the "Coinbase" or "Extra" field; it appears in plain text. Why is it visible? And what does the message say? The coinbase field is special in the block (not a regular transaction). It doesn't use RingCT or stealth addresses, so it's not private. From block 1 onward, all transactions are opaque. "The Times 07/Apr/2014 Bank of England warns over digital currencies"
