MetaMerkles - Smart contract ingestable metadata on groups of practically any size

WIP Tealscript Contracts for putting Merkle roots on chain & allowing other contracts to verify & fetch metadata against those merkle roots.

How does this work?

Merkle trees give us a log2(n) (very efficient) method of verifying whether a hash is part of a group.

We use these inside smart contracts to create arbitrarily large groups that are quickly verifiable.

We then attach metadata key-value pairs to the merkle root prefixed by the creators address so at any given time onchain, in any contract we can call the MetaMerkles contract to fetch metadata about a specific group, whether thats Assets, Addresses or Apps.

Potential use cases

• contract enforced royalties
• whitelists & blacklists of addresses
• anything that needs to verify large lists of assetIDs | addresses | appIDs

ARC58 smart wallet specific use cases

• Arbitrary groups for plugins with a single box key ( apps & addresses )
• Bartering - eg. i offer you 160 cheap assets for your 25 rarer ones
