Sandbox Blockchain

Sandbox Blockchain is the Poland's first  business and technology platform designed to accelerate the development of innovative blockchain solutions, made available free of charge to the approved users. The platform is a so-called sandbox, an isolated system that simulates the final production environment.  

Sandbox Blockchain, as the only solution of this kind in Poland, is intended to popularize solutions based on this technology. This project will not only help develop the economy through technology, but also by actively supporting entrepreneurship.

In Poland, the benefits of blockchain are not yet well-known or appreciated. Sandbox Blockchain aims to change this by offering a safe environment for hands-on testing of new solutions as well as the support and promotion of chosen projects.
