People have, I just dont think they realized it. And it looks like once they slipped up, they learned to disassociate the data on the blockchain and aggregate it together off network.

Shortly after the mass covid vaccine campaigns began, peoples medical data started popping up on ethereum.

I believe they were using these networks to crunch data about the vaccines and the effects. I also have this weird nagging thought that they prolly used a quantum AI to do it. Because it sounds like one was involved with the creation of the vaccine.

Moderna and IBM are teaming up to use generative artificial intelligence and quantum computing to advance mRNA technology, the development at the core of the company's Covid vaccine. The companies said they signed an agreement that would allow Moderna to access IBM's quantum computing systems and generative AI model.

Seems easy enough to do...

We develop smart contracts to automate the traceability of COVID-19 vaccines while ensuring data provenance, transparency, security, and accountability. We integrate the Ethereum blockchain with off-chain storage to manage non-critical and large-sized data.

Is this not someone just straight up admitting it?

In this study, we presented a method for securely and rapidly storing and retrieving COVID-19-related health information using smart contracts with the Ethereum blockchain. It enables the protection of patient information while facilitating more efficient research and communication.

That was oddly the time that ethereum hit a all time high.
