Hi. I wanted to share my new project Preturnio - a full text search engine for Bitcoin. With Preturnio you can search for text inside every OP_RETURN, Coinbase transaction and ordinal transaction since the genesis block. You can play with it over at https://preturnio.com

Block explorers can search for transactions, blocks and addresses but searching for arbitrary text is a challenge. Data is stored in the blockchain natively in hexadecimal format and not easily readable by humans. Preturnio solves this with an easy-to-use search interface. Simply enter the text you’re looking for and Preturnio will return highlighted results found in any OP_RETURN, Coinbase or Ordinal transaction. See when the data was created, which block it was confirmed in and other relevant details.

You can search for anything: source code, names, quotes, brc-20 tokens – any plain text you can think of, you can find in the blockchain with Preturnio. You can also share transactions with a direct link or even a preview image. Posting to Twitter will automatically create a Twitter card.

Ordinals are of course supported. Each inscription can be previewed inline or full screen. The platform support all transactions encoded with text-supported MIME types and we categorize inscriptions into two buckets – text and HTML. You can toggle to source code view with a familiar search interface to find the text you’re looking for inside the inscription payload. When you share an inscription, Preturnio will try to include a preview of the inscription whether it’s text or HTML. Once you’ve found your inscription, you can then search inside it with a familiar ‘Find’ experience to look for specific text.

Naturally each search result can be verified with a single click to on one of several public block explorers as well as ordinal explorers for inscriptions. It's also easy to copy the TX ID to verify on your own node.

Preturnio has also cross referenced all transactions against a published list of all known English words (more languages coming soon) so you can browse individual words stored somewhere on the blockchain. This is actually a lot of fun!

Check out the https://preturnio.com/docs to learn about other search features supported.

Feedback is encouraged and appreciated. Thanks for listening!
