So, Vitalik Buterin has just released a very ambitious plan for Ethereum through 2029. And it’s not just anything—we’re talking about a complete transformation of the base layer with faster slots, nearly instant finality, and protection against quantum computers.

The document making the rounds is called a strawmap—essentially a provisional roadmap that Justin Drake from the Ethereum Foundation helped structure. The idea is clear: reduce the slot time incrementally from 12 seconds to something between 2 and 4 seconds, using a square-root-of-2–style progression. It sounds simple in theory, but execution will require heavy research.

What caught my attention is how they’re thinking about all of it together. This isn’t just about making slots faster and done. There are improvements to the peer-to-peer network, erasure coding to reduce latency, changes to how attesters function. Basically, each component was designed to fit into the bigger puzzle.

Now, about finality—this is where it gets really interesting. Today, Ethereum takes about 16 minutes to finalize transactions. The plan proposes decoupling slots from finality and using an algorithm called Minimmit, which could bring finality down to something between 6 and 16 seconds. Some more aggressive scenarios talk in single digits. Like, imagine this: instead of waiting 16 minutes, you’d have certainty about your transaction in seconds.

One aspect that’s not trivial: quantum resistance. Buterin mentions that this will involve migrating to post-quantum hash-based signatures and hash functions friendly to STARKs. The community is still debating Poseidon2, Poseidon1, or even BLAKE3. Research is ongoing, but this is part of the plan through 2029.

The timeline is aggressive. If you do the math, we’re talking about approximately 1 billion seconds in days until then, making it clear that each fork needs to deliver. Buterin describes the process as a gradual ship-of-Theseus–style replacement—component by component—without breaking the network.

The real question is: will this happen? The strawmap isn’t a promise; it’s a proposal. It depends on research, decentralized governance, and community consensus. But the direction is set: faster blocks, quicker settlement, and a protocol prepared for the future.

If you follow Ethereum, it’s worth diving into this document. The technical details are dense, but the vision is clear. And if they can get even close to these goals, the experience of using Ethereum will change quite a lot.
