In his blog post, Buterin says the network needs to address these components simultaneously; otherwise the blockchain could fail.
Ethereum co-founder Vitalik Buterin laid out a new roadmap for the network to follow over the next few years, arguing that the world’s second-biggest blockchain should push forward on key goals of layer 2 scaling, wallet security and privacy in a coordinated fashion.
In a blog post titled “ the Three Transitions ,” Buterin wrote that the technical transitions need to be addressed simultaneously, to maintain key components of the protocol while providing a “global and permissionless experience to average users.”
“These three transitions are crucial,” Buterin wrote in the blog post. “But they are also challenging because of the intense coordination involved to properly resolve them.”
