Solidity devs:

How possible is it to store a large array to hold a leaderboard onchain?
It would need to be updated as it changes and shifted around.

My gut reaction as that this would be too expensive to make happen.
Is on a layer2 at least.

Or are there any better solutions?

Building /stokefire a mobile strategy game onchain. Run and own poolfish.xyz a calculator for LP providers. Built Potion solo and sold for $300k.

Do you need the sorting onchain? Or just the scores?

Would want sorting onchain so that onchain logic changes based on your relation to other players on the leaderboard.

"who are the 5 above you and 5 below you" Kind of thing.

We (Axis) implemented an on-chain sealed bid batch auction, which requires the decrypted bids to be sorted. This might be relevant for you?

TLDR:
- The sorting function is separate from other functionality.
- The caller can pass in the number of bids to [decrypt and] sort, so that it can be batched to fit within the chain's gas limit.
- Sort hints can be optionally passed in, to reduce gas costs.
