A place for developers to talk about building on Farcaster.

Sony released a camera with in-device signing a year ago. This was meant to be a forgery proof device.

Are there any other self signing devices out there? What about some sort of witness based protocol for image authenticity?

So Sony just announced their own L2 called Soneium. I wouldn't normally be particularly interested in this, however, Sony experimenting with L2s in combination with hardware-based signatures has me so excited for what's to come.

Imagine cameras with hardware-based signing that can broadcast attestations to Soneium after capturing. That's a timestamped transaction with a Sony signature attesting to a particular image hash. The image can be verified as a "true" raw image that was not falsified or tampered with.

Historically, Sony has had difficulties with in-device signing, but it would be an exciting step towards preventing forged / falsified images.

It's worth calling out that Sony is marketing this chain is more of a creator economy focused chain. However, I'm optimistic that it may expand to other experiments like this.
