Creating a smart contract on a blockchain ledger

This invention describes a system for managing product pre-orders using a smart contract on a public blockchain. A seller can launch a campaign with a minimum order quantity, and buyers commit to purchases. Once enough buyers collectively meet the minimum quantity, the seller is instructed to manufacture and distribute the product.

Why it matters: Filed before widespread adoption of Layer 2 solutions. Lower transaction costs and improved developer tooling make blockchain-based systems more practical now.
