Decentralized infrastructure network provider Nodle is working with companies such as Adobe and the Linux Foundation to use blockchain technology to prove the authenticity of real-world content captured by devices.
In a correspondence with Cointelegraph, Nodle co-founder Garrett Kinsman outlined the company’s upcoming ContentSign solution software development kit, which will use blockchain to prove the integrity of data from the moment of capture.
Nodle is introducing ContentSign into the Content Authenticity Initiative, a project led by Adobe and the Linux Foundation to create the media authentication standard of the future.

As previously explored by Cointelegraph, its main product is a network that uses smartphone Bluetooth connections to rent devices’ computing power, storage, and Bluetooth capabilities to expand the coverage of IoT networks.
Kinsman said ContentSign will be one piece of the puzzle to prove that a physical camera or device has captured a specific visual media and its corresponding metadata:
“The way this is accomplished is through a seal proving that a real camera has captured the video, that the video has been signed by a private key known only to that camera, and that the video’s footprint has been published to the blockchain. “
The technology could be useful for countless use cases, including journalism. As Kinsman hypothesizes, journalists could use cameras embedded with ContentSign technology to capture video or images of breaking news events:
“When footage is recorded, ContentSign ensures that it is tagged and signed with a unique private key unique to that specific camera.”
The film’s footprints are then minted as non-fungible tokens on the Nodle blockchain. The signature verifies that the content comes from an authentic source and is not manipulated or artificially generated.
Kinsman added that the current iteration emulates the service on mobile phones via ContentSign’s SDK, but future implementations may reflect technology found in cryptocurrency hardware wallets:
“In the future, the camera will embed a secure element similar to the one found on Ledger hardware wallets.”
As AI content generation expands, blockchain solutions like ContentSign may become critical, driving the need for solutions that distinguish real content from fabricated content.
“Blockchain’s inherent characteristics of decentralization, transparency, censorship resistance, and immutability provide an important framework for anchoring authenticity.”
Kinsman said ContentSign is being directly explored as a solution for the insurance industry to process claims accurately and completely. ContentSign will ensure that visual evidence submitted for insurance claims is authentic and has not been tampered with or generated by artificial intelligence.
