I just read about Vitalik's plan for Ethereum until 2029, and honestly, it's quite ambitious. Basically, he wants to transform the base layer into something much faster and eventually resistant to quantum computers. It all starts with shorter slots and near-instant finality.

The document currently circulating is called a strawmap — a blend of roadmap and open proposal for debate. It’s not an official decree, but a coordination tool for researchers, developers, and governance folks. Justin Drake from the Ethereum Foundation helped structure this.

The idea is to reduce slots incrementally. Today, Ethereum operates on 12-second intervals. The plan mentions using a "square root of 2" formula to reach 8, 6, 4, 3, and potentially 2 seconds. It sounds crazy, but Vitalik makes it clear that the last steps depend on intensive research. Think about it: reducing billions of seconds in network operation days — it's a massive transformation.

Now, the obvious question: how to maintain security with such short slots? That’s where improvements in the peer-to-peer network come in. Instead of each node receiving entire blocks from multiple peers, blocks would be divided into fragments — for example, eight parts, of which any four can reconstruct the full block. This reduces latency and bandwidth overhead without sacrificing security, just adds complexity to the protocol.

But the most interesting part is finality. Today, it takes about 16 minutes for a block to become final on Ethereum. The strawmap proposes decoupling slots from finality and using a Byzantine fault-tolerant algorithm with a single round. In the best case, finality could drop to 6 to 16 seconds. Vitalik acknowledges this is complex, but argues that the final protocol could be even simpler than the current Gasper.

And there’s more: post-quantum cryptography. Since all this is a comprehensive overhaul, Vitalik suggested bundling the change with cryptographic reforms, including hash-based signatures resistant to quantum attacks and a hash function friendly to STARKs. They’re evaluating options like increasing Poseidon2 rounds, reverting to Poseidon1, or adopting BLAKE3.

What’s interesting is that quantum resistance at the slot level could arrive before protection at the finality level. If powerful quantum computers suddenly emerge, finality guarantees might fail while the chain continues to operate.

Vitalik describes the entire process as a gradual replacement, component by component — like a "Ship of Theseus." Progressively reducing both slot time and finality, intertwined with a transformation of Ethereum’s consensus structure.

Of course, the strawmap isn’t a promise. It’s a proposal, a detailed plan inviting debate on how the base layer should evolve. Whether Ethereum will reach 2-second slots and single-digit finality by the end of the decade depends on research, governance, and organized chaos of decentralized consensus. But the direction is clear: faster blocks, quicker settlement, and a protocol prepared to survive future cryptographic eras.

If you’re following Ethereum’s evolution, this plan is essential. Meanwhile, ETH remains at $2.32K with a 1.68% increase in the last 24 hours — always good to keep an eye on technical updates that could impact the protocol.
