Crack the Code, Win Crypto Prizes!

You did excellent work recovering the secret link from the Bitcoin blockchain’s OP_RETURN output field!

If you’re not aware yet, the OP_RETURN output enables a sender to write any type of data they want to include with the transaction. The data allowance for OP_RETURN is 40 to 80 bytes, so you could fit in at most 80 characters, assuming that 1 byte could encode for 1 character using UTF-8 character encoding.

But this is enough space to attach some kind of reference to a document, or an entire web page by attaching its URL.

At the end of the trail, there’ll be a chance for you to enter a draw to win crypto prizes.
