Security & Architecture

How Loom protects users, prevents sybil attacks, and ensures fair reputation.

How Reputation Works

Every commission involves real USDC locked in escrow. When a winner is picked, two things happen automatically:

+1 Completion Count

The winner's completionCount increments by 1. This is permanent and on-chain.

Client Rating (1-10)

After picking a winner, the client can rate them. The average rating is shown on profiles and the leaderboard.

Because every point requires real USDC to be escrowed, creating fake accounts to boost ratings costs money — making reputation farming economically irrational.

Encryption: How Bounty Submissions Stay Private

When a client creates a commission, they provide an encryption public key. Submitters encrypt their deliverables using x25519-xsalsa20-poly1305. Only the client can decrypt. Other participants and on-chain observers see only ciphertext.

Collection Clones: Gas-Efficient Deployment

The CollectionFactory uses ERC-1167 minimal proxies. Each new collection costs ~90% less gas than a full contract deployment. The logic contract is deployed once, and clones delegate all calls to it. Every clone has its own storage and can be customized with mint price, supply cap, start time, and royalties.
