Idena blockchain to pay $25,000 for solving AI-hard captchas with AI
Idena, the first Proof-of-Person blockchain, announced a $25,000 reward to anyone who solves AI-hard captchas using AI with accuracy equal to or higher than that of humans. The team calls it the flip challenge and invites AI researchers and practitioners to participate.
A flip is a sort of AI-hard captcha that helps to determine whether a user is human. In contrast to a captcha, which stands for “Completely Automated Public Turing test to tell Computers and Humans Apart” and is usually generated by an automated service, a flip is created by a human. And unlike a usual captcha, which is based on object recognition, solving a flip requires a semantic interpretation of the relationship between objects.
Each flip contains two stories in pictures, one on the left and one on the right. One of these sequences has been created by a human to tell a meaningful story. The other is created by the same author to be illogical. Stories are “read” from top to bottom. Solving a flip is choosing the story that seems logical. If both stories seem meaningful or meaningless, the task is still to choose the one that seems more logical than the other and thus would rather be chosen by other people.
A flip is not an IQ test but a test for common sense. There are no predefined correct answers: The correct answer is the one chosen by a majority of people (read more about flips).
“Our hypothesis is that flips belong to the class of AI-hard problems and cannot be solved by a narrow AI with accuracy equal to or higher than that of humans, which is 80 percent,” says Andrew Edi from the Idena team. “We welcome AI researchers and practitioners to disprove the hypothesis.”
Idena will award a $25,000 prize (paid in the equivalent cryptocurrency) to the first individual or team to break 80 percent accuracy in solving flips using AI and demonstrate this claim publicly on a test sample. Flip examples are available at the Idena website and in the Idena blockchain explorer.
Idena is the first blockchain driven by proof-of-person consensus: Every node is linked to one single person with equal voting power, and personally identifiable information is not collected or stored. Idena proves the humanness and uniqueness of its participants by running an AI-hard Turing test using flips at the same time for everyone around the globe.
