Bitcast Launches Sentios to Deliver Continuous AI-Powered Security Scanning

Zcash, a multi-billion-dollar protocol, sat with an infinite mint bug in its code for years before someone finally noticed.

Bitsec (SN60) used its TWIST appearance to discuss Sentios, solving exactly that class of problem through continuous checking, catching what an annual security audit would miss. The service went live with the same subnet infrastructure already powering the audit product Bitsec has been selling to enterprise clients.

Why Continuous Checking Beats Annual Reviews

Annual security audits miss specific failure modes that only continuous scanning catches.

1. AI agents find more vulnerabilities than human researchers on the same code: Automated discovery outperforms manual inspection across every recent head-to-head comparison, especially on codebases with subtle logical flaws.

2. Stale codebases become vulnerable as models get more capable over time: New AI capabilities expose exploits nobody could have detected using the tools available when the last review ran.

3. The Zcash infinite mint bug represents the exact failure mode Sentios prevents: Years of undetected risk sitting inside a multi-billion-dollar protocol until AI capabilities caught up enough to spot it.

4. Point-in-time snapshots leave twelve-month gaps of unmonitored deployment: Anything shipped between audits stays unchecked until the next expensive review cycle arrives on the calendar.

Continuous scanning gives every code change immediate verification against whatever detection capability currently exists at that moment.

How Sentios Works Across Codebases

1. Smart contracts and traditional codebases both get equivalent coverage: Web3 protocols receive the same continuous inspection as mobile apps, Chrome extensions, and general software projects.

2. Real-world proof came from the OpenClaw scan finding hundreds of vulnerabilities: Bitsec submitted several pull requests helping the project close the exposures identified during that early evaluation.

3. The Fable comparison quantified the capability gap directly: Fable found 60 vulnerabilities on a paying client’s codebase, while Bitsec found more than 160 including several the frontier model missed entirely.

4. Open-source models keep pace with frontier alternatives at a fraction of the cost: Qwen models deliver comparable detection to Opus 4.8 at roughly 80% cheaper across Bitsec’s benchmarks.

Qwen beats Opus 4.7 on all metrics.

From our miner data, Qwen flat out has higher detection rates no matter how you look at it. at 25% the cost.

It surprised us too. Building and running solid evals is the only way to reveal the truth.

Coverage works the same regardless of what kind of codebase is underneath, smart contracts, mobile apps, or browser extensions all fall inside the same detection process.

Pricing That Scales From Hackathons to Microsoft

The service accommodates buyers across a wide range of budgets, from hackathon winners to enterprise teams securing every application they run.

1. Hackathon winners with prize money in the $10,000-$100,000 range can afford entry-level coverage: Vibe coders and indie hackers get access to genuine security infrastructure previously reserved for well-funded teams.

2. Enterprise clients like Microsoft pay more tokens for deeper coverage across bigger surface areas: The same underlying subnet handles both scale tiers, keeping infrastructure quality consistent regardless of budget size.

3. Existing audit budgets convert naturally to Sentios coverage: Continuous inspection replaces the annual review model at competitive total cost while catching more vulnerabilities per dollar spent.

4. Model choice inside the pipeline directly controls per-scan pricing: Buyers pick cheaper open-weight options when appropriate rather than defaulting to expensive frontier models for every scan.

Every buyer tier gets access to the same competitive miner pool producing the underlying security work.

The Bug That Waited Years

The Zcash infinite mint bug is exactly the class of problem Sentios exists to prevent from repeating anywhere else.

Continuous inspection gives protocols a defense that scales with attacker capability, closing the gap that widens every year between snapshot audits.

Sentios is live now and anyone can take a look at how it can help secure their codebases.
