The site continuously collects OP_RETURN data from the Bitcoin blockchain, then filters out non-human or meaningless content, keeping only natural-language text that actually carries semantic meaning.
Text written onto the blockchain cannot be deleted or edited — it becomes a permanent record.
I personally find this idea incredibly meaningful.
When you click on any entry, it opens as a card.
Each card represents a single immutable message.
Cards can be saved as images and shared.
