BAF explains why Stellar's protocol-level design is safer for payments than smart contracts. Built-in multi-signature accounts, compliance features, and automatic payment logic reduce complexity and attack surface. Particularly suited for CBDCs and cross-border transfers where security is paramount.
BAF's analysis argues for Stellar's protocol-level approach to secure payments. Rather than relying on Turing-complete smart contracts—which introduce complexity and attack surface—Stellar embeds critical financial functions directly into its consensus mechanism. Multi-signature account validation, compliance rule enforcement, and payment routing are protocol primitives, not application code. This design matters for high-stakes payment systems. CBDCs and cross-border transfers require certainty; the fewer external contract dependencies, the fewer exploit vectors. Stellar's built-in features eliminate the risk categories that have caused smart contract failures on other chains. Multi-sig accounts gain instant protocol-level enforcement. Conditional transfers happen at the network layer. The trade-off is flexibility: Stellar's approach is narrower than a general-purpose VM, suitable for payments and financial applications but not arbitrary computation. For the payment use case—especially institutional and cross-border—that narrowness is a feature, not a limitation.
