600-year-old Inca reveals ‘computer-like’ system that could store data, organize records and even mimic encryption

Before the advent of smartphones, spreadsheets, or even the written alphabet as we know it, the Incas’ way of managing information still seems surprisingly advanced. Their system, known as quipu, used knotted cords and color-coded cords to store records throughout their vast empire. It has long been thought of as primarily digital. More recently, the study was accepted in February 2026, although it proposes much broader content. Some scientists reportedly believe that quipu is not just a counting tool but a structured way of organizing and processing information. Almost like a primitive computing system. The idea sparked debate, curiosity and a fair amount of skepticism. Still, the possibility is interesting in its own right. A civilization without written language. However, managing complex administrative data across regions.

What is the structure behind the Kip Knot and Inca records

Over the years, scholars such as Marcia Ascher and Robert Ascher have suggested that the Kip Knot may represent a decimal-based number system. Every knot, every position carries meaning in a structured way. Other researchers, including Sabine Hyland, believe that quipus may also encode elements of language. A symbol that can represent a sound or concept. Some 95 possible markers have been proposed in some studies. These features appear to have more meaning than simple counting. The structure feels layered, almost modular. Not unlike how modern systems organize data into categories and subcategories.A single knot alone does not explain the entire situation. The system seems to rely on relationships between elements. This complexity makes things start to look less like ledgers and more like information frameworks.

look like quipu tree data structure for computer science

Computer scientist Richard Dosselmann puts forward a different perspective, looking at quipu from a data structure perspective. Along with colleagues Edward Doolittle and Vatika Tayal, he reportedly viewed the system as something to model rather than decode. The concept of their idea is simple. The Quipu line branches off from the main line. This hierarchy reflects the tree-like data systems used in today’s computing. Researchers use languages ​​such as C++ and Python to translate these properties into programming logic. They even created a file format designed around the quipu principle.

Quipu based prototype and its simple working principle

The team reportedly built a working prototype based on quipu logic. Spreadsheet model. Even image representation tools. These are not historical replicas, but modern applications inspired by the structure. Hierarchies allow adding data without having to restructure everything. The organization also scales in a linear fashion, which makes it suitable for hierarchical data sets such as census records or inventories.

Hidden layers of meaning and possible encryption

One of the more unusual aspects of the quipu is how flexible its structure appears. Researchers say disrupting the arrangement of wires at different levels could act as a form of data protection. Rather than adding encryption on top, it’s embedded into the structure itself. This is completely different from modern systems, where encryption is often applied separately. Here, the organization of data already includes mechanisms for obfuscating data.The Incas most likely did not devise a cryptographic system. Yet the properties of their method appear to allow this.

Why quipu is considered an early information system rather than a true computer

Calling a quipu a “computer” sounds like an exaggeration. No electricity, no processor, no binary code in the modern sense. Still, the comparison isn’t entirely inappropriate. What the Incas developed was a structured, scalable, and adaptable method of storing and managing information. A system that supports hierarchies, groupings, and summaries. A core feature of many computing systems today.Experts say it might be more accurate to think of quipu as an early form of information technology rather than a literal computer. A system built for organization, not just computing.
