According to reports on January 21, Bitcoin.com reported that there are growing concerns within the Ethereum ecosystem about its development speed. Jesse Pollak, head of Base (Bitcoin’s second-layer network), criticized Ethereum’s current roadmap as too conservative and called for the original 2027 update to be brought forward to early 2026. Ethereum Foundation developer Dankrad Feist shared a similar view, saying current growth plans "lack of ambition" and pointing to problems with the existing upgrade process. Feist also questioned the view that expansion can only be achieved in the second-layer network, emphasizing that large-scale expansion of the Ethereum base layer is feasible.
