Ethereum co-founder Vitalik Buterin has added to a newly released roadmap outlining how Ethereum plans to dramatically speed up the production of new blocks and the confirmation of transactions.<\/p>\n
Vitalik\u2019s comments<\/a> on Thursday offered more detail on a visual public roadmap<\/a> called \u201cStrawmap\u201d released by the Ethereum Foundation\u2019s Protocol team.\u00a0<\/p>\n \u201cFast slots are off in their own lane at the top of the roadmap, and do not really seem to connect to anything,\u201d said Buterin, noting that the rest of the roadmap is \u201cpretty independent of the slot time.\u201d\u00a0<\/p>\n Slot time is the time it takes for Ethereum to produce new blocks, currently around 12 seconds. The roadmap aims to get this down to as fast as 2 seconds, so the blockchain feels more like a live, responsive system rather than something that has to be waited for.<\/p>\n \u201cI expect that we\u2019ll reduce slot time in an incremental fashion,\u201d said Buterin<\/a>, suggesting reductions following a roughly square-root-of-two formula from 12 seconds down through 8, 6, 4, and eventually as low as 2 seconds.<\/p>\n He also suggested that p2p improvements, or upgrades to how Ethereum nodes communicate with each other \u2014 such as sharing new blocks and data without the need to download repeated data \u2014 can greatly reduce block propagation time, \u201cmaking shorter slots viable with no security tradeoffs.\u201d\u00a0<\/p>\n The second major improvement in the roadmap is to finality, or the point at which a transaction<\/a> is mathematically guaranteed to be irreversible, which is currently around 16 minutes.\u00a0<\/p>\n The future goal is finality between 6 and 16 seconds, achieved by replacing the current complicated confirmation system with a cleaner, simpler one that\u2019s also quantum-resistant<\/a>.<\/p>\n Related: <\/strong><\/em>Ethereum Foundation lists \u2018quantum readiness,\u2019 gas limits as 2026 priorities<\/strong><\/em><\/a><\/p>\n \u201cThe goal is to decouple slots and finality, to allow us to reason about both separately,\u201d explained Buterin.\u00a0<\/p>\n He said this was a \u201cvery invasive set of changes,\u201d so the plan is to bundle the largest step in each change with a \u201cswitch of the cryptography, notably to post-quantum hash-based signatures.\u201d<\/p>\n Buterin said that a consequence of this approach would be quantum-resistant slots before finality.\u00a0<\/p>\n \u201cOne interesting consequence of the incremental approach is that there is a pathway to making the slots quantum-resistant much sooner than making the finality quantum-resistant.\u201d\u00a0<\/p><\/blockquote>\n The network might \u201cquite quickly\u201d get to a regime where, if quantum computers suddenly appear, \u201cwe lose the finality guarantee, but the chain keeps chugging along,\u201d he said.\u00a0<\/p>\n \u201cExpect to see progressive decreases of both slot time and finality time,\u201d Buterin summarized.<\/p>\n The \u201ccomponent-by-component replacement\u201d of Ethereum\u2019s slot structure and consensus will produce a \u201ccleaner, simpler, quantum-resistant, prover-friendly, end-to-end formally-verified alternative.\u201d<\/p>\n The timescale for these changes is over the next four years, with seven forks planned roughly every six months. Glamsterdam and Hegot\u00e1 are already confirmed and slated for later this year.\u00a0<\/p>\n Magazine: <\/strong><\/em>Bitcoin may take 7 years to upgrade to post-quantum: BIP-360 co-author<\/strong><\/em><\/a><\/p>\n <\/div>\n Ethereum co-founder Vitalik Buterin has added to a newly released roadmap outlining how Ethereum plans to dramatically speed up the production of new blocks and the confirmation of transactions.
