Charles Hoskinson, founder of Cardano, has renewed his proposal for a significant upgrade to Dogecoin, often referred to as Dogecoin 2.0, aimed at integrating the meme cryptocurrency with Elon Musk's X platform.
The initiative, first suggested in March 2025 and reiterated in late October 2025, focuses on enhancing Dogecoin's scalability, speed, and interoperability to support microtransactions and social media use cases on X.
Hoskinson emphasized that the upgrade would modernize Dogecoin's infrastructure, allowing for faster transaction processing and higher throughput, while maintaining the coin's core identity. He expressed enthusiasm, stating, "I'd love to build it. It would be a ton of fun," and called for community collaboration to refine protocols and achieve technical advancements.
The proposal includes leveraging a pre-existing Bitcoin 2 roadmap as a foundation, with plans for improved smart contract compatibility and interoperability with other cryptocurrencies. Despite Hoskinson's efforts, no formal collaboration with Musk or X has been established, and market reactions have been modest, with Dogecoin trading near $0.184 and Cardano around $0.61, as investors await concrete developments.
Elon Musk has supported Dogecoin since 2021, with Tesla accepting it for merchandise, but X has not yet adopted it in its 'X Money' beta system, leaving the integration proposal in limbo.
