Verifier of Query Results

[dzobbe]

Hi all,

I have seen the example generating the proof and doing the verification. I need some help in building a verifier only code that uses the output received by SxT, e.g.:

{"requestId":"a88861df-64d2-44b6-8d6c-a5fe61f5a316","requestTimestamp":"2024-08-02T17:35:55.120001497Z","metadata":{"verificationHash":"xJU5uaAUFgxuoZJCpFged0AbxI7N6UWhvs6hAqer6ks="},"data":[{"att_data":"Sample attestation data","proof_order":1234567890}]} 

How can I use that verification hash and the data to verify them?

Thanks in advance.

Hey @dzobbe,
Great question. At the moment the SxT endpoint that you are getting that response from does not return that proof, but instead does verification as a service. We tried to make the API endpoint similar to the non-tamperproof pathway.

However, I'm happy to add the ability to return the proof from that endpoint as well, which will enable what you want. I'll post an update when we have it done.

@dzobbe This is almost done. We should have a new endpoint either this Monday or next. I will post back here when have it available.

hey man. Nothing?

Here you go:
https://github.com/spaceandtimelabs/sxt-proof-of-sql-sdk
It's still slightly in progress, but should be stabilizing quickly now that all the pieces are in place.

I think it is a private repo since I can't see it

[JayWhite2357]

It should be public now

Adding an update here: we've added a couple more examples in the SDK repo on how to use the SXTChain. Take a look here: https://github.com/spaceandtimelabs/sxt-proof-of-sql-sdk/tree/main/examples/deno for one example using javascript.
