With RosenBridge live on Ergo there is growing need for multiple oracle price feeds. Running an oracle pool for each single price feed seems an overkill. My proposition is simple:
Instead of publishing a single value like ERG_USD the oracle pool can publish a predefined list of let’s say 64 values with predefined indices.
Is this a viable idea? Are there any security concerns?
We have an Erg-USD Oracle Pool. In a dreamworld we would have Erg-USD Oracle Pool publishing 100 values for crypto spot price.
is it okay to deliver multiple data point at the same interval. Probably okay for e.g. gold and silver, but for gold and USD ?
I would not mix Gold and crypto spot price feeds.
Is it okay to reward for multiple data points with the same token
Only if the data verctor is homogenous (crypto spot prices).
One more thought on extensibility of the the price data feed. The oracle pool could initially post only ERG_USD price in a fixed length vector with other values beeing 0:
[ERG_USD, 0, 0, 0, 0].
New tickers can be added later (e.g. for a new rosen bridged asset), but can never be removed.
