It’s interesting to note that Ethereum has a very ambitious plan for the coming years. Vitalik Buterin recently shared a clear vision of how the network should evolve by 2029, and the document called 'strawmap' (a mix of a roadmap with a provisional proposal) is generating quite a bit of discussion within the community.

The core of the proposal is relatively straightforward: making Ethereum faster across multiple layers. Starting with slots — today, the network operates in 12-second intervals, but the plan is to gradually reduce this to 8, 6, 4, 3, and potentially 2 seconds, using a 'square root of 2' formula at each step. Of course, the final steps depend on intensive research.

But what’s really interesting is that this acceleration wouldn’t sacrifice security. As Buterin explains, the slot time will be treated as an adjustable parameter — reduced as confidence grows that the network remains secure. To enable this, improvements to the peer-to-peer network (P2P) are essential, including erasure coding. Instead of each node receiving entire blocks, they would receive fragments — for example, eight parts from which any four can reconstruct the full block. Internal statistics suggest that this approach could significantly reduce block propagation time at the 95th percentile, making shorter slots feasible without compromising security.

Now, if fast slots are a rhythm, finality is what truly matters for settlement. Currently, Ethereum’s finality takes about 16 minutes. The strawmap proposes decoupling slots from finality and adopting a single-round Byzantine fault-tolerant algorithm. In the final scenario, finality could drop to between 6 and 16 seconds — a radical change. Buterin acknowledges that this is more complex than it seems, but argues that the final protocol could be even simpler than the current Gasper system.

There’s also the issue of quantum resistance. Since this transformation is comprehensive, cryptographic reforms could be grouped with slot and finality changes. This would include post-quantum hash-based signatures and a hash function friendly to STARKs. Developers are still evaluating the best options here — discussions include Poseidon2, returning to Poseidon1, or even conventional hashes like BLAKE3.

A curious detail: quantum resistance at the slot level might arrive before protection at the finality level. If powerful quantum computers suddenly emerge, finality guarantees could fail while the chain continues to operate.

The entire process is described as a gradual component-by-component replacement — like the Ship of Theseus paradox. The strawmap isn’t an official promise but a detailed proposal inviting debate. Whether Ethereum will truly reach 2-second slots and single-digit finality by the end of the decade depends on ongoing research, governance, and decentralized consensus. But the direction is clear: faster blocks, quicker settlement, and a protocol prepared to survive hardware changes and cryptographic eras.
