We've started with a focus on news organisations and insurance companies. That said, we want to keep this free for individual users!

Thanks! What kinds of pro tools would you like to see? Exposure control, focus control, etc? Or more along the lines of metadata management?

Been working on this for a while. The idea is to give everyone a tool to create provably real photos and videos. Uses device level integrity and a distributed ledger for verifiability.

iOS version is more feature-rich and robust but Android is catching up.

Would love feedback :) What would you like to see? What applications do you envision for something like this?

The timestamps for PoET don't require centralized servers; the timers are local to the platform. RRR goes one step further and doesn't even trust local timers.

I feel like you've misunderstood the papers, and what the motivation behind them is. The argument isn't that Intel chips are more efficient, it is that these schemes simply don't require continuous computations.

As for the two schemes, you are correct about the first paper that it depends on the timeouts enforced by SGX. However, the second paper makes no such assumptions and doesn't even assume that the enclave is secure; all it relies on is the attestation service (which is remote).

SGX is disabled by default on most systems so it would have to be a very targeted malware

As the article states at the end, no one should assume that enclaves give you perfect security. They are most useful when used as a defense in depth mechanism: a way to increase the cost for a successful attack.

The main difference is spreading out the control of the database to multiple actors. No single entity is allowed to make unilateral changes to the state of the database.

Moreover, the line between permisisonless and permissioned blockchains isn't necessarily about who's allowed to join but rather which identity they use. For RRR, the only reason we limit ourselves to permissioned is because we require long lived identities to prevent sybil attacks; otherwise it's as "open" as any public blockchain.

The assumption behind PoET is precisely that you don't control a part of your machine (the SGX enclave). I agree that that's an unreasonable assumption which is why we developed RRR.

No one's gonna mention Bloackberry 10? In my opinion it was years ahead of the competition with its gesture based UI and Hub. Also, it felt like something that was truly different from the ios and android phones everywhere.
