Italian blockchain firm LKS created a not-fungible token (NFT)-based system that allegedly tin can forbid the spread of fake news.

According to an announcement sent to Cointelegraph on April xiv — other than countering faux news — LKS'south system also protects the copyright of digital content.

An LKS spokesman confirmed that the system creates an NFT which contains the identity of the publisher, publishing fourth dimension and a link to the original source. The token confirms the identity of the author (which is established through Know Your Customer procedures during the registration needed to utilise the organization), while the transaction timestamp proves publishing fourth dimension.

Articles are processed by a non-reversible mathematical function which creates an alphanumeric string — a hash — which is then saved on-chain. If a unmarried character of the article is edited, the hash changes and the hash saved on the blockchain tin prove that the commodity changed. When a publisher edits an commodity, he releases a new NFT with an updated hash linked to the older ane.

Blockchain's immutability put to use

LKS foundation founder Omar Baruzzo told Cointelegraph that blockchain is a good fit for such a project because of the immutability and traceability of transactions:

"[Those features permit] to create a procedure that tin can trace back to the user the responsibility of posting a content, therefore dissuading lying and permitting to empathize exactly who said something and when."

LKS plans to launch a kickoff version of the arrangement before long on blockchain-enabled social media platform Cam.TV. In the future, the firm plans to create a new version of it that also features notarization on the Bitcoin (BTC) blockchain.

Non the first blockchain content-tracking arrangement

As Cointelegraph recently reported, Italy's top news agency ANSA recently launched its own blockchain-enabled content tracking system dubbed ANSAcheck. The system employs tokens created on the Ethereum blockchain to track publication and editing.

While the LKS' project is similar to ANSAcheck, Baruzzo said that there are major differences betwixt the two systems:

"ANSA bank check just certifies [...] that an commodity is stored in ANSA's database. [Our system] will certify the beingness of Whatever content (news, but also content to protect), explicitly linking the content to the user [...] using a public blockchain to notarize the process."
