I just read a detailed breakdown by Vitalik of where Ethereum is headed in the coming years, and it really is an ambitious plan. The core idea is that the network’s base layer should become much faster and more resilient to future threats.

At the foundation is the so-called strawmap—this is not an official document, but rather a coordination tool that Justin Drake from the Ethereum Foundation published very recently. The document describes how Ethereum L1 should evolve through the end of the decade. And the main proposal there is gradual acceleration of the entire system.

Let’s start with the most interesting part. Slots are essentially time intervals during which new blocks are created. They currently last 12 seconds, but the plan calls for reducing them according to the formula sqrt(2)—that is, down to 8, then 6, 4, 3, and potentially 2 seconds. It sounds crazy, but Vitalik emphasized that the final steps depend on serious security research. The key point: slots are not just a technical parameter—they are the rhythm of the entire network.

One of the biggest problems is how to maintain security at those speeds. This is where improvements in peer-to-peer networks come into play. Instead of each node receiving full blocks from its peers, blocks will be split into fragments—e.g., into eight pieces, any four of which can reconstruct the entire block. This greatly reduces load on bandwidth and the delays caused by slow nodes.

Now, about finality. Currently, it takes about 16 minutes, which is quite long. Strawmap proposes separating slots from finality and introducing a single-round algorithm called Minimmit. As a result, finality could be reduced to 6–16 seconds. Can you imagine? Instead of 16 minutes—seconds. Vitalik honestly admitted that this is difficult, but believes the new protocol could even be simpler than the current Gasper system.

There’s also another important part of the plan—post-quantum cryptography. When powerful quantum computers become a reality, today’s signatures will become vulnerable. Therefore, a transition to hash-based signatures and STARK-compatible hash functions is planned. Developers are evaluating different options—from increasing the number of rounds in Poseidon to using traditional functions like BLAKE3.

An interesting point: quantum protection at the slot level could appear earlier than protection for finality. If quantum computers suddenly show up unexpectedly, guarantees of finality could weaken, but the chain itself will keep running.

Vitalik described the whole process as a gradual replacement of components—like the Ship of Theseus, where parts are swapped but the ship remains the same. Roughly one fork every six months is expected.

It’s important to understand: strawmap is not a promise, but a proposal for discussion. Whether Ethereum can reach 2-second slots and unambiguous finality by 2029 depends on research, governance, and how the decentralized network can come to an agreement. But the direction is completely clear—faster blocks, faster confirmation, and a protocol designed to survive both hardware changes and cryptographic eras.
