What is PolySwarm?
PolySwarm is a cybersecurity platform that takes a crowdsourced approach to malware detection.
Instead of relying on a single antivirus vendor, PolySwarm brings together an entire community of security experts who run specialized micro-engines (small anti-malware engines) to identify threats.
These experts compete to detect viruses, trojans, and other malware in real time. In exchange, they earn cryptocurrency rewards (when they are accurate).
Put simply, PolySwarm aims to provide faster, broader threat intelligence than traditional antivirus solutions by leveraging blockchain technology and a global network of engines.
How PolySwarm works
PolySwarm operates as a decentralized threat detection marketplace. You could think of it as a prediction market for malware. The platform ties economic incentives to malware scanning, so accuracy is rewarded, and mistakes have a cost. Here’s how PolySwarm works:
Submission of a suspect file/URL
Security teams or users submit a suspicious file, URL, or other “artifact” to the PolySwarm network (usually via a web portal or API). They attach a bounty in the form of PolySwarm’s cryptocurrency to incentivize analysis. This bounty is essentially a reward pool for whoever correctly determines if the item is malicious or benign.
Micro-engine analysis
Multiple independent security engines spring into action once an artifact is posted. These micro-engines, developed by malware experts around the world, automatically analyze the file or URL in parallel.
Each engine makes an assertion, which is essentially a verdict on whether the artifact is malicious or not. The engine backs that assertion by staking some of its tokens on it.
Staking tokens is a sign of confidence: if the engine is right, it stands to earn a reward; if wrong, it may lose its stake. This creates a competitive environment where engines are motivated to be as accurate as possible.
Consensus and PolyScore
The PolySwarm marketplace collects all the engines’ assertions and computes a PolyScore, which is an aggregate score reflecting the confidence that the artifact is malicious.
In other words, PolyScore is derived from the crowdsourced verdicts — if most engines (especially the ones staking higher confidence) say a file is malware, the PolyScore will indicate a high probability of malice.
This approach offers a quick, single indicator from potentially dozens of opinions. It is worth mentioning that PolySwarm’s system doesn’t require a human to manually “pick” which engine is right.
Instead, the truth emerges from the collective assertions. The underlying blockchain (originally Ethereum) smart contract holds the staked tokens during this process and ensures results can not be tampered with.
Validation and rewards
After an initial scanning, there is a brief validation period (around two weeks) to determine the ground truth of the file’s nature. During this time, designated arbiters — highly trusted participants in the network — double-check the engines’ findings to confirm what the file really is.
For instance, an arbiter might be a reputable security company that manually analyzes difficult samples. If consensus is unclear, the arbiters make the final call.
A real-world example is Kaspersky Lab, a leading antivirus company, which serves as an arbiter in PolySwarm. Kaspersky reviews certain samples for two to three weeks after initial scanning to decide if they were truly malicious or benign.
Once the ground truth is set, PolySwarm’s smart contract releases the bounties. Engines that guessed correctly (i.e., their assertion matched the ground truth) get paid out in tokens from the bounty pool, proportional to their stake and confidence.
Meanwhile, those who have guessed incorrectly lose their staked tokens. This “reward the accurate, penalize the inaccurate” mechanism ensures that over time the best-performing engines (and experts) thrive.
It also discourages any engine from cheating or spamming false alerts, because giving bad data costs them money.
Benefits of the decentralized approach
This blockchain-based design means that threat detection is trustless and transparent. All assertions and payouts are handled by smart contracts, so participants don’t need to trust a central authority — the code ensures everyone plays fair.
To cut a long story short, PolySwarm’s “proof-of-work” is malware detection skill, not compute cycles. The result is a self-policing ecosystem: if you build a better malware detector, you earn more, and if you bluff or lag behind, you quickly lose rewards.
PolySwarm tokenomics: How NCT powers the ecosystem
PolySwarm runs on NCT, an ERC-20 token used for all marketplace transactions. You use NCT to pay for file or URL analysis, and security engines stake NCT to make assertions. Rewards go to those who get the verdict right; incorrect assertions lose part or all of the staked amount.
Most enterprise users interact with PolySwarm through platforms that abstract away the token, but NCT powers everything behind the scenes. It incentivizes accurate threat detection and drives competition across the micro-engines.
PolySwarm distributed over 80% of its total 1.88 billion NCT tokens to the public through early access and ecosystem rewards. No new tokens will be minted, and rewards are capped, so the supply remains fixed.
Apart from scanning, PolySwarm also has NectarNet, a program that rewards you with NCT for contributing Passive DNS data. It also supports access-based models, where analysts spend NCT to run large-scale YARA searches or deep metadata queries. These features extend the token’s utility beyond the malware detection market.
Put simply, NCT acts as the fuel behind PolySwarm’s decentralized security model. It ensures everyone has skin in the game—analysts, engines, and validators. The fixed-supply design and real utility give it more staying power than many other cybersecurity tokens.
PolySwarm vs. traditional antivirus and threat intelligence platforms
| Aspect | PolySwarm | Traditional antivirus | Traditional threat intelligence platforms |
| Detection approach | Crowdsourced scanning by dozens of independent micro-engines in parallel. | Single-engine scanning by one vendor’s software on your device. | Aggregated data or scans from a fixed set of vendors (centralized). |
| Contributors | Typically, no reward for contributing data; vendors share data for mutual benefit or for reputation, but no cryptocurrency or bounty system. | Closed: only the vendor’s in-house research team creates signatures and detection logic. | Limited to partner vendors or data feeds; not open to independent contributors. |
| Incentive model | Engines get paid only if their assessment is accurate | No direct incentive for accuracy beyond maintaining reputation and market share (users pay a subscription regardless of daily performance). | Typically, no reward for contributing data; vendors share data for mutual benefit or for reputation. |
| Coverage of threats | Very broad and evolving coverage — specialized engines can focus on niche or emerging threats. New malware types may be detected by at least some engines quickly. | Coverage focused on common malware that the vendor knows about. | Broad in terms of sources (e.g., multiple AV feeds), but limited by overlap among those sources. If all sources miss a new threat, the platform misses it too. |
| Verdict determination | Consensus-based: multiple opinions combined into one PolyScore (with transparent scoring and arbitration). | Single-engine verdict: the AV either flags the file as malicious or not based on its own logic. No second opinion unless the user runs another AV product. | Multi-engine results: users often see a list of what each integrated feed or scanner says. |
| Cost and access | Marketplace model: users pay per scan or via subscription (often through an intermediary). Competition can lower costs; basic community access is free for limited use. | License model: pay for annual subscriptions or per-device licenses. Typically not cheap for businesses, and each AV license covers only that vendor’s protection. | Many threat intel platforms are subscription-based (and can be expensive); some community services (like public VirusTotal) are free but with limited features or rate limits for heavy use. |
Real-world use cases
PolySwarm is already in use across the cybersecurity industry. It’s not a theoretical project — it’s integrated directly into the tools analysts use every day.
Security platform integrations
PolySwarm doesn’t require its own dashboard. Its threat intelligence feed plugs into existing platforms like Anomali and Recorded Future through APIs.
When an analyst right-clicks a file hash in their tool, PolySwarm’s 40+ scanning engines return a real-time verdict (called a PolyScore), complete with malware family tags and detection counts.
This eliminates the need to cross-check across multiple antivirus dashboards. It makes PolySwarm a kind of automated malware oracle that fits neatly into SOC workflows.
Malware analysis and incident response
Security teams and MSSPs use PolySwarm as a faster, more robust alternative to VirusTotal. During incident response, analysts upload suspicious files and get rapid, consensus-driven results across dozens of engines.
PolySwarm often detects threats that slip past traditional AV tools, thanks to its incentive model. Organizations can scan attachments or intrusion artifacts and get verdicts within minutes, helping them act faster without needing their own malware lab.
Monetization for researchers
Security experts can deploy micro-engines on the network and earn NCT whenever they make accurate detections. This opens a monetization path for independent researchers and small antivirus developers. Instead of leaving niche detection scripts unused, researchers can turn them into active income-generating tools.
Threat hunting and malware research
The platform supports advanced threat hunting through YARA rule scans and retroactive searches. Researchers can mine PolySwarm’s database to find related malware samples or track campaign variants.
It also offers deep metadata on artifacts, allowing detailed analysis of malware behavior and spread patterns. This makes PolySwarm both a live detection engine and a long-term intelligence resource.
Limitations and challenges
While PolySwarm brings innovation to threat detection, it is not without certain trade-offs. One of the biggest challenges is trusting the quality of lesser-known engines.
Because the marketplace is open, not every micro-engine offers enterprise-grade accuracy. Although the staking model penalizes poor performance, some engines may still try to game the system or focus on quantity over quality.
Another limitation is complexity for individual users. PolySwarm’s core design is tailored for API integration and enterprise workflows. If you are a casual user, the platform may feel too technical or abstract — even more so if you are unfamiliar with concepts like staking or PolyScore.
Latency in reward resolution can also be an issue. Final verdicts often depend on arbiter confirmation, which may take days or even weeks. This makes PolySwarm less suited for instant response scenarios where speed is critical.
The project’s token dependency introduces volatility. Since NCT is required for all actions, fluctuations in its value can affect both cost predictability and incentive strength. If the token drops in value, the financial reward for accurate detection might not justify participation for some contributors.
Lastly, engine overlap with VirusTotal is a concern. While PolySwarm has unique contributors, several engines appear on both platforms. In those cases, the advantage lies more in the reward mechanism than in radically different coverage.
Is PolySwarm the next big thing in cybersecurity?
All factors considered, PolySwarm has indeed succeeded in offering a new approach to cybersecurity. However, it’s not a full replacement for every use case — not yet, at least. As of 2025, it appears to work best when integrated into a broader security stack, especially in environments that can handle delayed verdicts and value decentralized insights.
That said, the ecosystem is evolving, and it remains one of the most promising blockchain-powered projects to have come up in the cybersecurity space, particularly for those who prefer a threat intelligence infrastructure beyond conventional tools.
