provide sufficient information to run an arbitrum orbit chain

[matthewdarwin]

Eg https://apechain.hub.caldera.xyz/

How does it work? Is it Orbit-specific? OP chain will have a similar json config?

Should it be just rollupConfig field
{ type: orbit, config: https://ipfs.io/ipfs/xxxxxxx }

[YaroShkvorets]

Or maybe it's not rollupConfig but more generic chainConfig that can contain stuff like genesis.json for L1 chain

[matthewdarwin]

@Johnaverse can comment on this.

Orbit chain config example
parent-chain = L1 = Network
Data Availability = data-availability in node (Can be not as same as L1)
Rollup Stack = Arbitrum Nitro (All same for orbit chain)

Thanks. What about OP stack? Is it JSON config too?

[Johnaverse]

OP stack didn't come with json config but with environment config like this
