I was watching the movie "Paddington" with my daughter and they talked about the "Quipu", this is a secret code system of knots from the Incas
The Inca Empire functioned in no way inferior to that of European kingdoms. The State centralized agricultural and manufacturing production, based on mandatory quotas of personal labor, and all of this was perfectly managed by a complex and hierarchical body of officials.However, the Incas lacked an instrument that has always been considered indispensable for the maintenance of an empire: a writing system. Why did they never develop the art of letters? The answer is that they had an object that made it unnecessary, a unique and highly precise recording system called a quipu.The quipu (from the Quechua word khipu, meaning “knot”) was a textile device made of string and knots. Despite its material simplicity, the quipu was the basis of a complex system through which the quipucamayocs or quipus specialists kept records of everything that was important to the Empire. Spanish chroniclers of the 16th century were amazed by the amount of information that these threads could contain.
Putting some context on this, how could this be related to Bitcoin? or how could it be useful? Well, while watching the movie I just thought that I would love to know and handle this writing professionally to encrypt the secret keys of my wallets, just imagine walking down the street with a "nice bracelet" that when you open it actually has your keys encrypted in an ancient Inca language based on knots. IT WOULD BE AWESOME. Having "Inca decorations" in your living room, bedroom, kitchen and any place in your home and no one knows the reality that it hides, even in the car you could have a "copy", in your wallet, in the office where you work, there are no limits.
