Currently, most public blockchains are essentially failing. They reach a peak after listing on exchanges, generate a lot of hype, and then quickly decline, almost disappearing completely. This further reinforces the idea that public blockchains have reached a dead end, and that pursuing them has no future. However, Voidchain is different. It represents the future, offering the optimal solution to all the current challenges facing the blockchain world, and providing the best solution for IoT security. It is destined to become a landmark project, with an impact far greater than that of Bitcoin.
