Build Oracle Monitoring Tool

[jppade]

We are looking for an experienced Go developer who is interested in writing a service which monitors DIA oracles performance metrics.

The service should take these parameters as input:

1. Oracle address
2. Chain ID
3. RPC node

Given these input parameters, it should connect to the respective blockchain via RPC node and scan for oracle update events.
More precisely, the the following output quantities should be written into a database:

1. Oracle creation date
2. Oracle funding wallet address
3. Transaction hash
4. Block number
5. Timestamp of block inclusion
6. Asset which got updated
7. Asset value
8. Timestamp of data inside (part of the update)
9. Gas usage
10. Gas cost
11. Total transaction cost
12. Remaining gas funds in oracle funding wallet
13. TX sender

As there is no straightforward way to get the Oracle creation date/block/hash please proceed as follows:
Check for the latest transaction in the DB. If there is no entry, iterate backwards in history and fetch all transactions until you hit the contract creation. If there is an entry, continue from this block until now.

Furthermore, please:

• Write the service in Go
• Use timescaleDB as database
• Allow to input more than one contract address per blockchain and run the service on multiple blockchains in parallel
• Develop comprehensive unit tests to ensure functionality and robustness of the oracle monitoring service
• Deliver a docker container with entire functionality
• Provide documentation for setting up the service and running tests
