VRF Oracle

Oracle that generates verifiable random numbers.

Setup

1. Run run.js once, it'll crash at this point, that's ok.

node run.js

2. Generate your RSA private and public keys:

node genKeys.js

Your public key is now saved in pubkey.pem and the private one in privkey.pem in your data folder. The program shows the full paths after running.

3. Run run.js again. Note your address in the line like this:

====== my single address: UYBHEJNRNQCC3MGK5UO7T6YUHPWTSLXC

Kill the process with Ctrl-C.

4. Edit vrf-oracle-template.oscript and replace your_oracle_address and your_public_key with your address and public key respectively. You can remove the header/footer like -----BEGIN PUBLIC KEY----- and line-breaks from the public key.

5. Deploy this AA from your Obyte wallet. Note its address.

6. Edit conf.js and set exports.vrf_oracle_aa to the address of the newly deployed AA.

7. Send some Bytes to your VRF oracle address from step 3 (not to the AA address). They are needed to pay fees.

8. Run run.js again and leave it running as a daemon:

node run.js 2>errlog

Type Ctrl-Z, then bg, then exit the session.

Your oracle will watch for randomness requests from City AA (and maybe other consumers that need secure randomness) and generate and post randomness accordingly.

If you need to add more consumers, edit consumer_aas in conf.js.
