Preturnio has launched a blockchain search engine for Bitcoin users. Users will be able to look for text within any OP_RETURN, Coinbase transaction and ordinal transaction since the genesis block of Bitcoin transactions. It will return highlighted results found in any OP_RETURN, Coinbase or Ordinal transaction with information on which block it was confirmed in, when it was created and other relevant details. Preturnio has categorised inscriptions into two buckets – text and HTML and supports all transactions encoded with text supported MIME types.
