Ethereum co-founder Vitalik Buterin has joined a debate over high school mathematics, arguing on September 21, 2026, for less emphasis on trigonometry and greater focus on basic calculus, linearity, nonlinearity and systems thinking. His comments followed a proposal from Ryan Petersen, Chief Executive Officer of Flexport, to replace subjects such as geometry and trigonometry with statistics and applied economics. Buterin instead advocated reshaping mathematics education from within, including introductory single-variable and multivariable calculus and analysis of how interconnected systems respond to small perturbations. He said such foundations could support fields including artificial intelligence, cryptography and biomedical science, while noting that he had rarely used the tangent double-angle formula in his professional career. The discussion coincides with Buterin’s 2026 draft EIP-8288, which proposes using recursive STARKs at the mempool level to aggregate cryptographic signatures and computational validity proofs. The proposal uses dependency frames to declare transaction constraints, aims to reduce overhead associated with post-quantum signature schemes and remains subject to developer consensus in a future network hard fork.
