Note to Jeffrey Goldberg and all journalists: How to prove facts using blockchain | Opinion

Here’s why Pi Network, Jasmy, LTC, Ethena, and altcoins are down

Amid the backdrop of a Signal chat leak scandal involving top U.S. officials, journalists could explore blockchain as a tool to prove facts without revealing sensitive content.

At first, the White House denied that the chat ever existed. But when it became clear that there was too much evidence to refute, they shifted tactics, denying that the chat ever contained any classified information of national security significance. And indeed, what proof can journalist Jeffrey Goldberg present after leaving that chat? Moreover, the chat was set to self-destruct messages after a period of time.

So imagine a court hearing where parties are required to present evidence, and the only available proof consists of screenshots—in other words, virtually nothing, as such evidence is almost impossible to verify. The solution lies in a cryptographic method known as proof of existence without disclosure. It involves two basic elements: cryptographic hashes and reliable timestamps. This can be done on blockchain manually—if one knows the process—or through a variety of applications and services offering blockchain-based timestamping proofs.
