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?

Maybe possible if you use a binary or red-black tree? The worst case rebalancing scenario + block gas limit might limit the number of participants, but the best/average case would probably be fairly efficient.

Do you want it on chain for composability or provenance? If just provenance I’d say just update a hash of the leaderboard on chain. And lazy composability would then be to expose the leaderboard via oracle and verify against the hash.

I can try to shill you Cairo language (Starknet), and you can use @dojoengine to put your games and leaderboard fully onchain 😅 There's others building games fully onchain there that can help onboard you and/or you can stral ideas from them. Lots of public repos to copy+paste lol

it all you need is to go from score to rank and rank to score (but not, for example, rank to player) then sparse trees and a little magic could possibly work https://github.com/0xFlicker/ranker/blob/main/src%2Franker%2Franker.ts

Sorting is the hard part here... Could store this onchain but keep a smaller mapping of the top 10?

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