The Thoughts of Satoshi Nakamoto on ZK-proofs: A Glimpse into the Mind of Bitcoin’s Creator

Zero-knowledge proofs have revolutionized the world of cryptocurrency, offering solutions for privacy, scalability, and security. In recent years, ZK-proofs have emerged as one of the most significant trends in the blockchain industry, attracting substantial investments and powering major Ethereum scaling protocols. But what did Satoshi Nakamoto, the pseudonymous creator of Bitcoin, think about ZK-proofs?

A Better Version of Bitcoin

In August 2010, a Bitcointalk forum user named “Red” raised concerns about the lack of privacy in Bitcoin transactions. They pondered whether there could be a way to improve privacy while preserving the benefits of the blockchain. Another member of the forum suggested that zero-knowledge proofs could be the solution. Nakamoto, in response, expressed interest in the concept, stating that a much better and more convenient implementation of Bitcoin would be possible if a solution was found.

However, Nakamoto recognized a fundamental challenge in applying zero-knowledge proofs to Bitcoin. The issue of “double-spending,” where an actor spends the same digital tokens multiple times, requires global knowledge of all transactions. Nakamoto was skeptical about how zero-knowledge proofs could address this problem. He stated that proving the absence of double-spending necessitates knowing about all transactions and ensuring that the double-spending scenario is not included.

Years Later, Someone Cracks the Code

Although Nakamoto had reservations, the cypherpunk community eventually found a solution. In 2016, Zcash, a privacy-focused cryptocurrency, was launched. Zcash was built upon Bitcoin’s original source code and was the first peer-to-peer cryptocurrency to implement zero-knowledge proofs. This allowed users to shield their wallet addresses, enhancing privacy in transactions.

Eli Ben-Sasson, the founding scientist of Zcash, went on to create StarkWare, a company that utilizes zero-knowledge proofs to scale Ethereum through rollups. Ben-Sasson acknowledges the pivotal role that Bitcoin core developers’ early enthusiasm for ZK-proofs played in his journey. He attributes his “Eureka moment” to the Bitcoin 2013 conference, where Mike Hearn, a well-known developer and Bitcoin adopter, declared ZK-proofs as having a significant impact on the future of blockchain.

So, What Would Nakamoto Think?

Based on Nakamoto’s previous statements and his emphasis on privacy, it is clear that he was in favor of using ZK-proofs to enhance privacy in transactions. Nakamoto himself took precautions to remain anonymous, utilizing IP-masking browsers such as Tor. He even dedicated a section to privacy in the Bitcoin white paper, suggesting keeping public keys anonymous to preserve transaction privacy.

Although Nakamoto’s thoughts on ZK-proofs were expressed nearly a decade ago, it is likely that he would continue to explore their potential integration into Bitcoin. Taking into account the current state of blockchain technology and the need for scalability, it is reasonable to assume that Nakamoto would recognize the importance of ZK-proofs in achieving Bitcoin’s vision as a global currency. The recent developments with ZeroSync and its ZK light client for Bitcoin demonstrate the growing interest in bringing scalability and privacy to the world’s leading cryptocurrency.

Editor Notes: Unlocking the Future of Crypto

If Satoshi Nakamoto were still active today, we can imagine how excited he would be about the advancements in zero-knowledge proofs and their potential impact on privacy and scalability in the cryptocurrency space. As we strive to unlock the full potential of blockchain technology, it is crucial to stay informed about the latest developments.
