Vitalik Buterin, the founder of Ethereum, recently shared his insights and recommendations for the Bitcoin community during a discussion on Twitter Spaces. Buterin emphasized the importance of BTC’s exploration of scaling solutions beyond payments and encouraged people who support “the cryptocurrency king” to adopt a more experimental approach.

While acknowledging the potential of Bitcoin, he also highlighted the challenges posed by its unique political dynamics. Joined by “altcoin slayer” Eric Wall and Bitcoin developer Udi Wertheimer, Buterin discussed the significance of scaling and shared valuable lessons that the Bitcoin community can learn from Ethereum‘s experience in this area.

Scaling Solutions for Bitcoin

Vitalik Buterin

The primary issue identified by Buterin was BTC’s slow transaction throughput, which necessitates layer two scaling approaches to enhance transaction speed. He proposed that Bitcoin could benefit from scaling solutions such as Plasma or ZK Rollups, both of which have been successfully implemented on the Ethereum network. Buterin specifically praised rollup implementations like Optimism and Arbitrum, which could serve as case studies for Bitcoin’s scaling efforts. He urged the community to maintain an open mind, particularly regarding ZK-snark-based solutions, indicating his preference for these technologies.

Ethereum’s ongoing efforts to explore various scaling solutions were highlighted during the discussion. Buterin mentioned the upcoming EIP-4844 update, which introduces blob blocks and enables an impressive throughput of up to 100,000 transactions per second. By emphasizing Ethereum’s commitment to continuous innovation, Buterin conveyed the message that experimentation and evolution are crucial for the long-term success of any blockchain platform.

Security Concerns and Fee Market

Addressing concerns about Bitcoin’s security model and the 21 million hard cap, Buterin acknowledged the challenges associated with sustaining the network’s security in the future. He referenced Ordinals as a potential solution, as they provide a reasonable fee market to compensate for diminishing block subsidies. Buterin also expressed enthusiasm for the “return to builder culture” facilitated by Ordinals, characterizing it as a positive development that challenges the notion of maximalism within the cryptocurrency community.

Bitcoin Security

Despite their differences, Buterin identified several commonalities between Ethereum and Bitcoin. Both chains boast claims of immutability, face challenges with layer-1 privacy, and highlight the complexities of operating within decentralized consensus models. Buterin concluded the discussion on an optimistic note, suggesting that a world with at least one of these chains is preferable to one without any. His aim was to foster collaboration and bridge the gap between both communities for the benefit of the overall blockchain ecosystem.


Vitalik Buterin’s advice to the Bitcoin community emphasized the need for scaling solutions and experimentation beyond payments. Drawing from Ethereum’s experience, he highlighted the success of various scaling approaches such as Plasma, ZK Rollups, and Ordinals. Buterin encouraged the Bitcoin community to maintain an open mind and learn from these experiments to enhance BTC’s transaction throughput and security. By identifying shared traits and emphasizing the importance of collaboration, Buterin aimed to promote a more inclusive and innovative blockchain ecosystem.
