A system and method for assetizing and monetizing hashtags is disclosed. The system and method include a hardware processing device communicably coupled to a distributed ledger-based platform. The hardware processing device assetizes the hashtag by converting it into a non-fungible token. The method also includes facilitating transactions with respect to one or more rights associated with the hashtag. A decentralized search engine comprises a Hashtag Master to select posts from a selection panel; to determine the posts to be placed on the top of the portal/search engine display, to insert widget advertisements onto any display page of any hashtag, and to remove an inserted widget advertisements from any display page of any hashtag within a preset period. The decentralized search engine validates an ownership of a hashtag to produce NFT on a block chain using a minting process.
