In a quiet snow-covered town lived Nicholas, a ten-year-old boy with an insatiable curiosity for technology. While his friends enjoyed building snowmen or writing traditional letters to Santa Claus, Nicholas spent his afternoons surrounded by books and online tutorials, learning about blockchain, that mysterious technology that, it was said, would change the world.

Fascinated by its ability to encrypt information securely and transparently, Nicholas decided he would do something different that year. Instead of sending a paper letter, he would use blockchain to communicate with Santa.

The idea came to him one afternoon while he was helping his mother bake cookies. “How does Santa read all the letters he receives?” he asked. “It must be very difficult.” His mother smiled, but did not have a precise answer. Nicholas, intrigued, thought that there must be a safer and more efficient way to get his message across. A way that would ensure that only Santa could understand it.

From paper to Blockchain

With his usual determination, Nicholas got to work. He researched the creation of smart contracts and discovered that he could write a message on the blockchain using a private key that only he and Santa would have access to. For days he worked on his computer, while Christmas lights flickered in his room.

She wrote her letter, asking not only for a drone, but also for more books to learn from and enough winter clothes for the children in her neighborhood who were suffering from the cold.

Using a digital wallet of his own creation, he uploaded his message to the Ethereum network. He then generated a public key and sent it to the North Pole via an email that, according to urban legends, some tech elf could read. Now all that was left to do was wait.

The challenge of Santa Claus

At the North Pole, Santa Claus was faced with something he had never seen before. Instead of the usual piles of letters, the elves brought him a screen with an encrypted message. The blockchain address was clear, but the content was incomprehensible. “What is this?” asked Santa as he adjusted his glasses.

Spark, a young elf with a passion for technology, stepped forward. “It’s an encrypted message, boss. It looks like someone wrote it using blockchain.” Santa, an old soul still used to making lists on parchment, was surprised. “Can you decipher it?”

Spark smiled. “Of course, but you’ll need to use the private key this kid sent. Everything on the blockchain works with trust and unique ownership. The kid trusts you to be able to decrypt it.”

Santa, with his classic ho-ho-ho, received the private key that Nicholas had sent. Minutes later, the message was decrypted, revealing the most innovative letter he had received in centuries.

Santa's response

Moved by Nicholas’ spirit of generosity, Santa decided that this little boy deserved something special. With the help of Spark, he not only delivered the drone and books, but also created a community blockchain in Nicholas’ town where families could collaborate to make sure no child was left cold in the winter. It was a transparent system where everyone could see the donations and make sure they went to those who needed them most.

Nicholas woke up on Christmas morning to find a drone in his tree, along with a handwritten note from Santa. “Dear Nicholas, thank you for teaching us a new way to communicate with me. With children like you, the future is in good hands. Keep learning and helping others.”

Nicholas's face lit up as he read it. Deep inside, he knew he had started a new tradition that perhaps other children would want to follow as well. After all, if he had learned anything, it was that the magic of Christmas could be modernized without losing its essence.

And so, in a snow-covered city, with blockchain and generosity as its main ingredients, a Christmas emerged that no one would ever forget.
