SNARKs (Zero-Knowledge Succinct Non-interactive Argument of Knowledge) and STARKs (Zero-Knowledge Scalable Transparent Argument of Knowledge) are cutting-edge zero-knowledge proof systems that allow one party to prove the truth of a statement to another without revealing any additional information. These technologies have garnered significant attention due to their potential to enhance security, protect user privacy, and support Layer-2 network scalability. SNARKs, introduced in 2012, are known for their efficiency and speed but require a trusted setup ceremony, which poses potential security risks. In contrast, STARKs, introduced in 2018, do not require a trusted setup, offering stronger security but with potentially higher verification costs and longer processing times. Despite their differences, both SNARKs and STARKs are pivotal to blockchain technology, enabling scalable, private, and efficient transactions. They are actively researched to unlock new use cases and drive innovation in the global economy, with SNARKs being initially more widely adopted due to their earlier development, despite some associated security challenges.
