The Oracle of Delphi was critical infrastructure in ancient Greece—pivotal in the major political decisions and historical events of the time. This coin (in a Berlin museum) depicts one founding myth, a clever surveying trick by Zeus to site the Oracle at the center of the world.

Many thanks to @taliakaplin for @CNBC interview today on misleading narratives around AI and blockchains. Also how focus on prices distracts from blockchain innovation (right after news about Bitcoin price swings!). ...and a bit on The Oracle.

Thanks to Uniswap for their generous support. Until the emergence of tools to mitigate MEV—something we're working on—I hope that predicting impact will be a useful stopgap measure. @UniswapFND @FKoushanfar
