Network-Native Security

By Zavdi Gelfand

The current approach to smart contract security is fundamentally reactive. Audits happen before deployment, monitoring happens after transactions execute, and incident response happens after funds are lost. This paradigm needs to change.

The Problem with Reactive Security

Traditional security measures for smart contracts follow a predictable pattern:

  1. Pre-deployment audits - Experts review code for vulnerabilities
  2. Bug bounties - Incentivize white-hats to find issues
  3. Monitoring - Watch for suspicious activity
  4. Incident response - React when something goes wrong

Each of these steps has value, but they all share a critical flaw: they don’t prevent the bad transaction from executing.

Network-Native: A New Paradigm

What if security could be enforced at the network level? What if invalid state transitions were simply impossible?

This is the core insight behind the Credible Layer. Instead of detecting and responding to attacks, we prevent them from ever happening.

How It Works

  1. Define your invariants - What states should your protocol never enter?
  2. Write assertions - Express these invariants in Solidity
  3. Submit to the network - Assertions are enforced at the sequencer level
  4. Transactions that violate assertions are dropped - Not rolled back, dropped

The key difference is when enforcement happens. Traditional security catches problems after execution. Network-native security prevents invalid execution entirely.

Why This Matters

For protocols:

  • No more race against attackers
  • Deterministic security guarantees
  • Simpler security model

For users:

  • Verifiable protection
  • No reliance on external monitoring
  • Transparent security rules

For the ecosystem:

  • Reduced systemic risk
  • More institutional capital
  • Faster innovation

The Path Forward

Network-native security isn’t just an improvement—it’s a fundamental shift in how we think about smart contract security. The question isn’t whether to adopt it, but when.
