Crypto: Buterin Outlines 4-year Roadmap To Speed Up And Quantum-proof Ethereum

“The goal is to decouple slots and finality, to allow us to reason about both separately,” explained Ethereum co-founder Vitalik Buterin.

Ethereum co-founder Vitalik Buterin has added to a newly released roadmap outlining how Ethereum plans to speed up the production of new blocks and the confirmation of transactions.

Vitalik’s comments on Thursday offered more detail on a visual public roadmap called “Strawmap” released by the Ethereum Foundation’s Protocol team.

“Fast slots are off in their own lane at the top of the roadmap, and do not really seem to connect to anything,” said Buterin, noting that the rest of the roadmap is “pretty independent of the slot time.”

Slot time is the time it takes for Ethereum to produce new blocks, currently around 12 seconds. The roadmap aims to reduce this to two seconds to improve responsiveness.

“I expect that we’ll reduce slot time in an incremental fashion,” said Buterin, suggesting reductions following a roughly square-root-of-two formula from 12 seconds down through eight, six, four, and eventually as low as two seconds.

He also suggested that p2p improvements, or upgrades to how Ethereum nodes communicate with each other — such as sharing new blocks and data without the need to download repeated data — can greatly reduce block propagation time, “making shorter slots viable with no security tradeoffs.”

The second major improvement in the roadmap is to finality, or the point at which a transaction is mathematically guaranteed to be irreversible, which is currently around 16 minutes.

The future goal is to achieve finality within six and 16 seconds, by replacing the current complex confirmation system with a cleaner, simpler one that’s also quantum-resistant.
