Can any cryptocurrency/blockchain enthusiasts help me with a question I have? I don't feel like asking /g/ or /sci/.
I dont know that much about it and am trying to get my head around some of it.

Chainlink is supposed to act as an Oracle, which maintains all of the bookkeeping between series of blockchains, correct?
If each LINK attached to each a data unit is permanently indebted with that information, wont there be some kind of cap on how much information an oracle could keep track or is there just a fuck huge amount of them? And how much data could one of them hold? Is there a term for this specific thing?
And what would stop someone form looking at Chainlink's code and just making a copy of it as their own oracle? And can oracles connect with other oracles?
Thanks.
