Vitalik Buterin Gives 33% Odds on Near-Practical SNARK FHE iO Overhead by 2030
Ethereum co-founder Vitalik Buterin assigns explicit probabilities to SNARK, FHE and iO reaching near-zero and single-digit overhead for real-world computation by 2030.
Ethereum co-founder Vitalik Buterin stated a 33% chance that SNARKs, fully homomorphic encryption and indistinguishability obfuscation reach 1+ε overhead in everyday real-world computation by 2030.
Buterin assigned a 60% chance that all three achieve single-digit overhead, measured by energy use plus amortized compute, below 10x.
Current status
He said one of the three is more likely to arrive before the end of the decade, with single-digit-overhead SNARKs the most probable.
Buterin noted that specialized hash functions and some large-model inference are already close to that range.
What remains open
No quantified timelines, implementation paths or adoption metrics were provided beyond the stated probabilities.
Overhead definitions and exact measurement methodology remain unspecified in the statement.
