Blockchain is a new technology. It can help in many areas, like education and money matters.

In schools, some teachers use blockchain to keep students’ study records. For example, your test scores or graduation certificates can be stored here. When you want to show these to a new school or a job, you can share them quickly. And no one can make fake ones—this technology keeps them safe. Teachers can also use it to check how you are learning more easily.

What makes blockchain special? It is not controlled by one person or company. Many people keep the same data, so it’s hard to change or lose. But there are problems too. Setting it up costs a lot, and people need to learn how to use it.

You may have heard of Bitcoin. It is a digital money, and blockchain is the technology behind it. blockchain works like a digital notebook. It writes down every time people use Bitcoin—everyone can see these records, and they never go away. This makes it almost impossible to cheat.

Banks like using blockchain too. It helps them send money between countries faster, and it costs less. But some people don’t like it. For example, making Bitcoin uses a lot of electricity, which is bad for the Earth. Also, some governments think bad people may use digital money to do illegal things. Even so, experts say blockchain will change how we use money in the future.
