Key Takeaways
Ethereum published a draft roadmap calling for seven hard forks by 2029 to deliver near-instant finality and 10,000 transactions per second on Layer 1.
Ethereum laid out a plan to slash transaction finality to as little as 6 seconds and boost Layer 1 throughput to 10,000 TPS through seven hard forks by 2029. The draft document, nicknamed the Strawmap, was published by Ethereum Foundation researcher Justin Drake.
"The cumulative upgrades represent a ship of Theseus transformation where every component gets replaced over time," Ethereum co-founder Vitalik Buterin said, highlighting the scope of the proposed changes.
The roadmap targets reducing finality from roughly 16 minutes to 6 to 16 seconds via a mechanism called Minimmit, a single-slot finality system. Layer 2 capacity could reach 10 million TPS through data availability sampling, according to the Strawmap. For context, Visa processes about 1,700 TPS on average.
The plan also prioritizes post-quantum cryptography, specifically hash-based signatures designed to resist attacks from quantum computers, with fork milestones for quantum readiness by 2029. Most Layer 1 blockchains have not yet begun addressing quantum threats, giving Ethereum a potential competitive advantage if it executes on schedule.
The Strawmap includes native shielded ETH transfers, allowing users to transact without exposing balances and transaction history to public blockchain scanners. Privacy upgrades have been a long-standing request from the Ethereum community, and the roadmap formalizes a timeline for implementation.
Since the 2022 Merge transition from proof-of-work to proof-of-stake, Ethereum has shipped incremental hard forks including Dencun in 2024 and Pectra in 2025. The Strawmap builds on this trajectory with a more aggressive cadence of roughly one fork every six months through 2029.
Post-quantum cryptography emerges as a competitive differentiator
The quantum-resistant push comes as the broader crypto industry grapples with the threat of future quantum machines cracking elliptic-curve cryptography, the security backbone of most blockchain networks. Google published research in March suggesting encryption-breaking quantum systems could arrive by 2029, earlier than previously anticipated. Bitcoin, the largest cryptocurrency by market cap, is viewed as especially susceptible because its 17-year transaction history has exposed millions of public keys, according to a June 2026 working paper by researcher Ahmed Raza Muhammad Umer that estimated roughly 35 percent of Bitcoin's circulating supply could be vulnerable to a future quantum attack.
Ethereum's Strawmap includes fork milestones for post-quantum readiness by 2029, aligning with the Ethereum Foundation's stated goal of achieving full quantum protection by that year.
What the roadmap means for ETH holders
Seven hard forks in roughly three years is an aggressive pace for a network securing hundreds of billions of dollars in value. Investors should watch whether the first fork in the sequence ships on schedule — that will signal whether the six-month cadence is realistic or aspirational. Ethereum has a history of delayed upgrades; the Merge from proof-of-work to proof-of-stake, originally anticipated years earlier, did not occur until September 2022.
If executed, the Strawmap would position Ethereum as the fastest major smart-contract platform by finality time, potentially pressuring competing Layer 1 blockchains such as Solana and Avalanche to accelerate their own roadmaps. The post-quantum cryptography component could also become a structural advantage as the industry moves toward quantum-resistant standards.
