I was really impressed with @APRO Oracle dual channel price feeding design in this test. The thing that really stood out to me about APROs dual channel price feeding design was that it was not fancy. It actually fixed a problem that people often do not think about. APROs dual channel price feeding design is something that I think is really useful because it deals with an issue that APROs dual channel price feeding design solves, in a way.
When we talk about price feeds people usually think of them as one pipeline.. If this pipeline has a problem or gets slow everything that relies on it will be affected. APRO does things a bit differently. It separates the way it collects data from the way it checks that data is correct before it gets to the contract. This means that the price feeds are handled in a careful way by APRO.
This setup was really good during the test. When one channel was slow the other channel kept giving us the information we needed. This meant we did not have surprises and we could always see what was going on. The test of the setup showed advantages. The setup felt like it was checking everything not just giving us data. The reference data, from the channel was very helpful.
What is really important is how this impacts the reliability of contracts. Contracts do not require prices all the time. They need prices that're consistent and make sense. The dual channel design is focused on making sure prices are stable than being really fast. This is what matters most for reliability. The dual channel design prioritizes stability, over speed which's important for contracts to have consistent and defensible prices.
This also shows that APRO understands what really happens in the world. Sometimes networks fail. Sometimes data sources change. APRO does not think that everything will always be perfect. It gets ready for problems and arguments. Solves them before the data is final. APRO plans, for noise and conflict. Resolves them before the APRO data becomes final.
The result is a price feed that behaves predictably when things get tough. You might not even notice this when everything is quiet. It is really important when things are not quiet. The price feed is something that we need to behave under stress so we can count on the price feed to do what it should do.
Seeing this in action reinforced the sense that APRO is built by people who expect their system to be tested. That expectation shapes better design choices and this dual channel approach is a good example of that thinking.
