Blockchain is an amazing technology: it solves problems that either cannot be solved in any other way or cannot be solved truly effectively using other existing technologies.
This technology ensures that the applied logic we have written cannot change or be manipulated in any way. It can record every transaction and every action and sign it in a way that cannot be forged or hacked. In addition, by representing assets digitally and uniquely, there can be no duplicates and every action is chronologically recorded. The unique retention of information in a chain of interconnected blocks in a non-disassembly, modification or separation digital connection prevents or compromises system reliability. Moreover, decentralizing the system to many original copies allows it to be restored even if several sites are damaged.
