What Is VeraPlayer + Proof of View by Verasity?

Verasity’s Proof of View (PoV) is a patented fraud detection system that verifies whether a video view is real or fake. It does this by using a combination of blockchain technology, machine learning, and artificial intelligence. Once verified, each view is recorded on a public blockchain so that advertisers, content creators, and buyers can trust the view counts.

This technology is part of Verasity’s wider ecosystem and is embedded directly into VeraPlayer, the company’s proprietary video player. Proof of View is built to stop bots, fake traffic, and ad fraud—an issue that affects over 65% of video ad views, according to industry estimates.

Why Verasity Built Proof of View

The online advertising industry has long struggled with inflated view counts. Platforms like Google and Facebook rely on views to determine how much advertisers should pay. But most views go unverified, making them easy to fake or manipulate. This undermines the trust advertisers place in platforms and distorts the value of content creators.

Verasity saw this problem and responded with a system that ensures:

• Verified views based on strict criteria
• Transparent and auditable records on-chain
• Automated fraud detection before views are counted

The goal is to make every view count by making every view verifiable.

How Proof of View Works

At the heart of Proof of View is a verification module that operates alongside Verasity’s video tools. The system uses a multi-step process to validate views:

Key Components

• Verification Module: Runs computer-executable code stored in non-volatile memory.
• Processor: Receives requests, records data, and communicates with the blockchain.

Verification Steps

1. A viewer requests to watch content.
2. The system captures metadata: device info, session behavior, viewing duration, and other data points.
3. The data is hashed into a “database chunk.”
4. That chunk is added to a public blockchain block.
5. The hashed data is compared with the blockchain for consistency.

Only after completing these steps does the system log the view as valid.

Auditable and Tamper-Proof

To make the system auditable and efficient, Verasity uses a Merkle Hash Tree. Each individual view is hashed, then combined with others to create a top hash. This method ensures the data can’t be changed without detection.

Use Cases of Proof of View

Proof of View is not limited to ad views. Verasity has extended the technology to cover:

• NFT authenticity checks: Buyers can verify view counts of video-based NFTs.
• Channel valuation: When a content creator wants to sell a stake in their channel, Proof of View verifies how many real views their content has received.
• Content Marketplaces: Views influence pricing. Proof of View ensures prices reflect actual engagement.

Patent and Legal Backing

Verasity’s Proof of View has been granted patents in:

• United States
• China
• European Union
• South Korea

The company first secured its U.S. and China patents in 2021 and continues to expand its IP portfolio. This gives Verasity legal protection and reinforces its claim as the originator of this system.

Key Technical Concepts

Blockchain Use

By appending hashed view data to the blockchain, Verasity ensures:

• Public visibility
• Tamper resistance
• Permanent record-keeping

Machine Learning & User Behavior

The system monitors:

• Viewing duration
• Pause/play activity
• Mouse movements
• Session length

These patterns help detect bot-like behavior.

While the system offers high accuracy (99.9% in internal tests), it relies on data points that may evolve with user behavior and tech changes. However, the flexible architecture of Proof of View means it can adapt and integrate with evolving platforms and standards.

Conclusion

Verasity’s Proof of View is a comprehensive solution designed to solve a real and persistent problem: view fraud. By using blockchain, hashing, and behavioral data, it ensures advertisers and publishers know which views are real. The technology forms a core part of Verasity’s VeraPlayer and VeraViews products and is backed by patents in several regions.
