Vitalik Buterin Predicts 60% Chance of Cryptography Breakthrough for Ethereum Privacy
Vitalik Buterin, co-founder of Ethereum, recently expressed a 60% probability that advancements in cryptography could lead to a transformative shift in Ethereum's privacy capabilities. Speaking on September 6, Buterin highlighted that technologies such as SNARKs (Succinct Non-interactive Arguments of Knowledge), fully homomorphic encryption (FHE), and indistinguishability obfuscation (iO) may eventually operate at costs significantly lower than traditional computation.
Buterin suggested that there is a 33% chance that all three technologies could approach near-zero additional overhead at scale. This potential breakthrough could enhance privacy beyond simple transaction concealment, making private proofs easier to generate and allowing applications to compute directly on encrypted data.
While Buterin's timeline for these advancements is cautious, he indicated that at least one of the technologies, likely SNARKs, could achieve single-digit overhead by the end of the decade. However, he clarified that Ethereum does not need to wait for these breakthroughs to improve privacy. The Ethereum roadmap includes various strategies to enhance privacy, such as anonymous RPC systems and private information retrieval.
Current proposals include frame transactions to separate fee payments from actions and keyed nonces to obscure activity correlation. Although these remain proposals, they highlight Ethereum's proactive approach to privacy.
Buterin also noted that while SNARKs are the most mature of the three technologies, FHE and iO could further revolutionize decentralized finance by enabling shared encrypted states and concealing program logic, respectively. The implications extend beyond Ethereum, potentially impacting the roles of intermediaries in financial systems.
In conclusion, while Buterin's 60% scenario could accelerate advancements in privacy technologies, the remaining 40% indicates that progress may be uneven, with meaningful privacy improvements achievable through existing technologies.

New Developments in Ethereum's Rollup Ecosystem
- An Ethereum prototype has demonstrated an 11–18× reduction in estimated reconstruction computing work across 1,000-node simulations.
- The reduced design allows operators to minimize duplicated work with a simpler change than the full RowDAS networking proposal.
- Researcher Csaba Kiraly's report from September 3 describes this reduced design as a potential first step toward RowDAS.
- In simulations, the estimated network-wide reconstruction cost dropped significantly, from 48.6 CPU-seconds to 2.75 CPU-seconds under the new design with a 10% supernode share.
- The reduced design retains a delayed recovery role for high-custody nodes, preserving a PeerDAS-style backstop.
- Full RowDAS, specified in draft EIP-8371, aims to add another recovery route through row channels for smaller nodes to pool data.
- The immediate focus is on reducing processor work for recovery, with broader resilience benefits expected from a future row layer.
