Cloudflare's Will Papper stated that the company requires a blockchain capable of scaling across multiple machines to support its infrastructure needs. Papper identified Ethereum's original sharding design as a viable solution for payment processing, emphasizing the fungible nature of currency where "a dollar is a dollar." The comments highlight Cloudflare's interest in leveraging established blockchain architecture to achieve horizontal scalability. By focusing on sharding mechanics originally proposed for Ethereum, the company aims to implement a distributed system suitable for high-volume payment transactions without requiring complex state management.
