Higher-order logic proof assistant developed to support formal verification and used to verify the Nitro Isolation Engine.
"Why not just use Lean?"
Lawrence Paulson contextualizes Lean's current prominence within 60 years of formal mathematics history (from AUTOMATH in 1968), arguing that landmark achievements like Jutting's 1977 formalization required original thinking rather than following crowd consensus.
"Why not just use Lean?"
Lean's current dominance in formalized mathematics risks eclipsing 60 years of foundational work in proof systems like AUTOMATH (1968) and HOL Light.
Isabelle/HOL: The proof assistant behind the Nitro Isolation Engine
AWS deploys Nitro Isolation Engine—the first formally verified hypervisor—using Isabelle/HOL's quarter-million-line proof to mathematically guarantee cloud isolation.
