TL;DR:
Eli Ben-Sasson, founder of Starknet and co-founder of Zcash, has revived a fundamental discussion regarding Satoshi Nakamoto‘s vision. Unearthing archives from 2010 reveals that Bitcoin’s creator did not merely permit, but actively encouraged the existence of alternative blockchains for specific use cases.
The technical debate highlights that, unlike modern maximalism, the pioneers viewed Bitcoin as a solid foundation upon which to build. Historical data indicates that Hal Finney himself discussed the possibility of purchasing tokens from other networks using BTC, laying the groundwork for interoperability and today’s crypto economy long before the DeFi boom.

The evidence suggests that Satoshi Nakamoto was, above all, a pragmatist. During discussions regarding BitDNS (which would later become Namecoin), he firmly opposed recording domain data on the main Bitcoin blockchain to preserve its efficiency. This stance challenges the narrative that any other chain is a mistake or a scam, suggesting that specialization was part of the original blueprint.
Furthermore, the concept of merged mining proposed by Satoshi allowed new projects to survive by leveraging Bitcoin’s computing power. This vision of a multichain ecosystem sought collaboration rather than the elimination of competitors—a perspective Ben-Sasson uses to question the rigidity of today’s “monochain” extremists.
In summary, the legacy of Bitcoin’s early years points toward a diverse ecosystem where innovation was not restricted to a single network. If a task required a different architecture, Satoshi’s philosophy dictated that a new tool should be created to fulfill it.
