Creating Veri — A Next-Gen Programming Language

Currently developing Veri, a programming language designed for the AI era. Combining formal verification, memory safety, and AI-native design to eliminate entire categories of bugs at compile time.

What Makes Veri Different:
  • Bugs Caught at Compile Time — Mathematical proofs, not just tests. Overdrafts, null pointers, race conditions—impossible by design.
  • AI-Native Design — Unambiguous syntax means AI generates correct code, not "almost correct" code.
  • Domain-Driven TypesAmount where self > 0 means negative amounts won't even compile.
  • Zero-Cost Safety — Rust-like performance without garbage collection pauses.
  • Designed for Critical Systems — Banking, payments, healthcare—where bugs cost millions.

Will be open-sourced to advance the industry. Compiler built in Rust.

payment.veri
// Types that prevent bugs by design
type Amount = Decimal where self > 0
type Balance = Decimal where self >= 0

fn transfer(from: &Account, to: &Account,
             amount: Amount)
    requires from.balance >= amount
    ensures from.balance == old(from.balance) - amount
    ensures to.balance == old(to.balance) + amount
{
    from.withdraw(amount)  // Can't overdraft
    to.deposit(amount)     // Proven correct
}
Why This Matters:

This code cannot compile if overdraft is possible. The compiler mathematically proves correctness—no unit tests needed for these guarantees. Imagine eliminating entire categories of payment bugs before deployment.

Designing for Tomorrow

Not just solving today's problems—architecting systems that stay ahead of the curve
