Verifiying RNG

Verification of your RNG is very simple, and can be done directly on random.org.

Go to: https://api.random.org/signatures/form.

You will need the randomness and signature from your response from arrng. The easiest place to get these is arrscan, but for full confidence you can find them on-chain in a block explorer of your choice (e.g. etherscan).

Below is an example response on etherscan. https://etherscan.io/tx/0x7e5543de86c3202942dd48bcce83efe7bb819aaee25d56b83866f62cb27dc3ce

To see the response details scroll down to 'More Details', and click '+ Click to show more'.

In the section 'Input Data' select 'Decode Input Data'

You want the full text from apiResponse_ for the field called 'random' on the random.org verification page.

NOTE - etherscan modifies the formatting of this response, including removing commas and adding in carriage returns. To use data directly from etherscan you need to add back the commas and correct spacing to the JSON. This can be tricky. Alternatively, you can copy the response from arrscan (in the field 'API Response') and use that for verification, after checking that the content of the two is the same.

The full text from apiSignature_ goes in the 'signature' field.

In this example these are:
