Blockchain: A Solution to Bias in AI Training Data?

Executives at the World Economic Forum in Davos discuss the potential of blockchain in addressing bias and misinformation in AI training data.

Blockchain technology, which gained popularity with the launch of bitcoin in 2009, has the potential to revolutionize various industries. One area where blockchain could prove to be a game-changer is in addressing bias and misinformation in the training data used for artificial intelligence (AI) models. At the World Economic Forum in Davos, executives discussed the possibility of using blockchain to create a tamper-proof ledger of AI training data, ensuring transparency and accountability in the development of AI systems.

The Concerns Surrounding AI Models and Bias

One of the primary concerns with AI models is the potential for biased or inaccurate information to be embedded in the training data. This can lead to AI systems providing answers that are influenced by these biases or misinformation. To overcome this challenge, researchers and developers have been exploring ways to ensure the integrity and reliability of AI training data.

Blockchain as a Solution

Blockchain technology offers a potential solution to the issue of bias in AI training data. By leveraging the immutable and transparent nature of blockchain, developers can create a system that securely stores and tracks the data used to train AI models. This allows for the verification and auditing of the training data, ensuring that biases and false information are identified and addressed.

Casper Labs, a blockchain firm focused on business applications, recently partnered with IBM to develop a system that utilizes blockchain for AI training data. Medha Parlika, the CTO and co-founder of Casper Labs, explained that their product checkpoints and stores datasets on the blockchain, providing a verifiable record of how the AI model has been trained. This enables developers to roll back the AI and undo any learning that may have led to false information or biases.

Addressing AI Hallucinations

One of the challenges with AI systems is the occurrence of “hallucinations,” where the AI provides false information. By utilizing blockchain, developers can identify and address these hallucinations by referring to previous versions of the AI model. This rollback feature allows for the correction of any erroneous learning and ensures the AI system’s accuracy and reliability.

The Potential of Blockchain in AI Training Data

While blockchain has been discussed in various industries, the application of blockchain in AI training data could be a “killer use case” for the technology, according to Sheila Warren, CEO of the Crypto Council for Innovation. The verification and checks and balances within AI systems could benefit greatly from the transparency and immutability provided by blockchain technology. By utilizing blockchain, developers can create a trustworthy and accountable AI ecosystem.


As the field of AI continues to advance, addressing bias and misinformation in training data is crucial to ensure the reliability and fairness of AI systems. Blockchain technology offers a promising solution to this challenge by providing a tamper-proof ledger of AI training data. By leveraging blockchain, developers can create a transparent and accountable AI ecosystem, mitigating the risks of biases and false information. The partnership between Casper Labs and IBM highlights the growing interest in utilizing blockchain for AI training data, signaling a potential shift in how we approach the development and deployment of AI systems. As blockchain technology continues to evolve, its integration with AI could pave the way for more ethical and unbiased applications of artificial intelligence.
