1) Contract owner CANNOT withdraw ETH. 2) True. The Price Oracle is a separate contract that I want to modify to be more like Ark's superdelegate method - a certain number of delegates stake Unum and get to control the price oracle, and in return get to collect the fees from the Unum contract. There's a bit of a chicken-and-egg problem with that for now - it requires people who are interested in collecting a part of the Unum fee. 3) True, but the contract is backed by more than ETH. If the entire crypto market tanks, you'd have to wait for a recovery before you could sell your Unum.

Very interesting. Do you have any further info on 'Ark's superdelegate method'? I only found yourself mentioning it via google. I'm interested in how oracles / off-chain data can be decentralised.

This may explain: https://ark-guide.readme.io/v1.0/docs/what-are-delegates

There are a few currencies doing delegate so I may have confused "super delegates" with another currency.

If I'm interested in becoming one of your price oracle delegates, what do I do?

For now that's just a plan. Assuming people become interested in, and start using Unum, I'll post more about it on the blog.

For now, I'd really appreciate any help in getting people to take a look at Unum.

2) have you looked into towncrier?

I did, and it seemed like a good solution, except I wanted to be able to instantly get the price info, and town crier is a request/response method. The Price Oracle part of unum caches the price, so I can use a .call method from the Unum contract to retrieve the data immediately.

Everyone and their mother is starting an alt-coin.

My next-door neighbor's sister's hairdresser has started one as well. Every 10th coin you mine, you get 15% off your next appointment. Have you looked into that one yet?

TownCrier is actually pretty interesting, it's leveraging Intel SGX to verify requests
