Is it real or is it AI? Blockchain is positioning itself as the verification standard in the face of advancing Artificial Intelligence.

The infrastructure of crypto assets, blockchain technology, is offering a technical solution to the authenticity challenges posed by generative AI through the use of timestamps and immutable identifiers on the blockchain.

The exponential growth of artificial intelligence has transformed the creation of digital content, but it has also introduced unprecedented challenges to information integrity. 

Michael Selig, chairman of the U.S. Commodity Futures Trading Commission (CFTC), has pointed out that the difficulty in distinguishing between real and synthetic material—such as images, deepfake videos, or fake news—represents a latent risk to the stability of financial markets and social cohesion. 

Given this scenario, blockchain technology emerges not only as a support for financial assets, but also as a notarial record capable of certify the origin of any digital file.

Blockchain as the "digital notary" of the synthetic age

According to Selig, the fight against disinformation is finding a powerful ally in blockchain technology. Its decentralized nature and ability to immutably record data give it the potential to become a key tool for validate the authenticity of digital content. 

“I hope that by combining prediction markets with blockchains, we can see how decentralized trust and truth can act as a check against misinformation, blatant falsehoods, and the threat of unbanking.”, said Selig during the BOCA 2026 event.

Faced with the risks posed by artificial intelligence in generating manipulated or synthetic information, blockchain introduces a level of verification that cannot be deceptively reproduced.

One of the fundamental elements of this approach is the use of timestamps o timestampsEvery piece of genuine content can be recorded on the network with an exact date and time of creation. This information cannot be modified or deleted, allowing for the establishment of a reliable timeline that serves as evidence of its origin.

Added to this are the digital identifiers based on the blockchain, which acts as a unique "digital signature".

Using cryptographic techniques, each file acquires a kind of digital signature that can be traced at any time. In this way, anyone viewing a text, image, or video has the possibility of... Check if it comes from a legitimate source or whether it is an artificially generated imitation. For Selig, this traceability system could bring transparency to the digital ecosystem and help restore trust in information circulating on the internet. 

Technological interdependence: "You can't have AI without Blockchain"

One of the most relevant premises in the current debate on digital security is the need for an infrastructure that supports the expansion of artificial intelligence. 

According to Selig's view, for AI to be a safe and reliable tool in global markets, it requires the transparency and immutability that define cryptocurrency technology. "You can't have AI without Blockchain" Selig summarizes this symbiotic relationship: while AI generates efficiency and content on a large scale, blockchain provides the layer of truth needed to audit these processes.

Large-scale projects are already implementing these concepts. World (formerly Worldcoin), led by Sam Altman, uses biometrics and on-chain ledgers to issue the World ID, a protocol that verifies a user's humanity against the proliferation of bots. Meanwhile, tools like AgentKit allow autonomous AI agents to identify themselves and perform verified transactions, ensuring their actions are cryptographically backed.

Even prominent figures in the sector, such as Vitalik ButerinThe founder of Ethereum, [names omitted], have advocated for the use of zero-knowledge proofs and other cryptographic tools to validate identity and content online. Under this approach, blockchain technology is transforming and evolving, moving beyond being merely a network for transferring value in digital assets and becoming an essential veracity filter for 21st-century data infrastructure.

Blockchain and regulation: the balance between innovation and control

Given the importance of blockchain technology, Selig argues for the need for clear regulations that allow for technological advancement without neglecting the security of the financial system. 

Solutions based on this technology require a legal environment that fosters innovation and clearly defines the limits of oversight. Therefore, agencies like the CFTC propose a regulatory approach that operates with a “minimum effective dose,” meaning intervening only as much as necessary to maintain transparency and protect users, without stifling developers' creativity.

Under this vision, the goal is to maintain the United States' leadership in technological innovation, preventing the brain drain to countries with more flexible regulations. Instead of controlling the code or imposing technical restrictions, the aim is to regulate financial activities that rely on blockchain. In this way, according to Selig, the economy is protected without limiting the potential of an infrastructure that could become essential in monitoring the behavior of artificial intelligence.
