Name of Project

Lit Protocol Cross Chain Validation

Proposal overview

Mission

Lit Protocol uses threshold cryptography to enable the internet’s decentralized security model, and steward the internet’s distributed secrets.

Lit Protocol is an open source, decentralized utility that uses encryption to provide blockchain users access to digital and real world experiences. The network acts as a decentralized access control list (ACL) which leverages on-chain data to grant users access to content, software, and other decentralized networks.

Proposal Overview

Lit Protocol provides encryption and access control in a self sovereign and decentralized manner through the use of threshold encryption. With an already active user base performing signing and encryption using BLS threshold encryption, Lit is now implementing ECDSA threshold encryption to enable signing and verification of messages with EVM compatible chains and all others supporting similar elliptical curve security.

An identified use case is decentralized cross chain asset and condition validation for use within the Harmony ecosystem.

Lit proposes to implement distributed cross-chain signing available to Harmony’s dApp builders that can be accessed through the Lit JS SDK. The solution would allow a Harmony dApp developer to validate conditions within another EVM chain - for example, does a given user hold a BAYC NFT on the Ethereum mainnet? Use of condition information is virtually limitless - it can be used gate access within dApps through to provide purchasing incentives to asset holders.

To accomplish decentralized cross chain signing, Lit’s nodes perform independent validation of chain conditions (e.g. confirming asset ownership) and create independent signature shares - these shares can be recombined within the client’s browser, maintaining decentralization constraints. Signatures can then be stored and/or validated on the Harmony blockchain for reference at any time.

Lit proposes to use a Harmony grant to implement and create a reference sample including implementation of secure cross chain condition validation, smart contracts on the Harmony blockchain that can validate signatures independent of the LIT networks and a simple sample UI for common uses.

This foundational work targets specific asset held by users, but use cases would also include any on-chain verifiable conditions, including DAO membership, value style information (e.g. user holds $10k of ETH), and any combination of related that can be applied through boolean logic.

@DavidLSneider welcome to Harmony.

Curious to know which teams / projects would be most suitable for a dACL solution? It makes sense to build this lego block into the composable ecosystem, and I’d like to ensure that you’re successful upon launching this together with a project that would need this.

I think the Lit Protocol will provide tremendous value to the Harmony ecosystem. I’ve used them before for a couple projects and think access control is the next big thing. And ECDSA threshold encryption will perhaps be even bigger – once Lit builds this, we’ll use cross-chain ECDSA to put multichain identities on Harmony.

We’ve been in touch with the Harmony team who wants to use this for a number of games!

If we come across a use case that demands for an integration with Lit protocol, we’ll reach out. But for now, we will pause this proposal until further notice. Without a specific example of which games to integrate with, it will be difficult for us to decide on moving forward here.

We’d like to see this initiative more integrated into Harmony’s existing ecosystem, such as DeFi, NFTs, Games, Wallets, etc. Without those integration points, it will be difficult to justify the technical support resource and funding for your proposal.

We can alternatively support your team to launch on Harmony and we’d be happy to circle back with your team to be discuss further once there are more datapoints on adoption after it goes live.
