Quotes that support claims

Nightfall enables the firm’s business partners to transfer tokens privately using Ethereum’s security while being cheaper than the base network. It also uses a technology that binds a verified identity to a public key through digital signatures to try to stem counterparty risk.

The new design also enhances privacy through zero-knowledge proofs that allow transaction validation without revealing underlying data.
