Vitalik has just shared some very interesting details about Ethereum's technical roadmap, and there are some points worth paying attention to.

The current focus is on two main fronts in the execution layer. First: the state tree structure will move away from the hexadecimal Keccak MPT architecture and migrate to a binary tree with more efficient hashing (EIP-7864). The benefit here is significant – a fourfold reduction in Merkle branch length and, more importantly, a 3 to 100 times increase in proof efficiency. Additionally, the cost of accessing adjacent slots drops considerably.

But the most ambitious plan is the long-term one: gradually replacing the EVM with the RISC-V architecture. Yes, the entire Ethereum Virtual Machine. The idea is to improve execution efficiency, facilitate proof compatibility, and simplify protocol design. This won't happen all at once – it will occur in three phases: first in precompiles, then allowing developers to deploy with the new VM, and finally transforming the EVM into smart contracts running on the new architecture.

What makes this relevant is that it addresses real bottlenecks Ethereum faces. The network becomes more efficient, proofs become more feasible on the client side, and this paves the way for what comes next. Basically, it’s about laying the groundwork for the next generation of scalability. I found it interesting because it shows that the current focus is on deep optimizations, not just superficial patches.
