Blockchain technology has been around for more than a decade, but most people have only heard about it recently. Blockchain is a distributed database that can be used for storing any kind of data. Each block in the chain has a record of the previous block’s hash, allowing the data to be verified and prevent hacking. Entries are permanent, transparent, and searchable. A blockchain is resistant to modification of the data. The blockchain concept allows information to be stored globally on thousands of servers. Blockchain technology creates an opportunity to improve the world’s trade systems. The blockchain is spread across many servers, and the data it contains cannot be modified or deleted even if some of the servers went down. Now let’s get to the 6 Things you should know about blockchain.
1. What are blocks?
The data in blockchain are stored in BLOCKS. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. The timestamp proves that the transaction data existed when the block was created. The hash acts as an identifier for that data, allowing you to see if someone has changed or altered any part of it without knowing its exact contents. For example, if you have access to someone’s computer system and want to alter or delete some files on it—even if they’re encrypted—you would have to change their hashes before doing so because changing them would mean that those same files now had different hashes than what was originally stored on disk somewhere else in their system (or even across different systems).
2. Entries are permanent, transparent, and searchable.
The blockchain is a permanent ledger that records every single transaction of its users. It’s transparent, meaning that anyone can see the transactions and their details. And it’s searchable—you can use this technology to find any information stored in its database at any time.
As we’ve seen, this technology has implications for everything from business to government operations to medicine and science research. But what does all this mean for us?
It means that we need to be aware of how blockchain technology is affecting our lives. The distributed nature of this decentralized database makes it possible for anyone to view, edit and transfer data on any given topic without needing an intermediary (like a bank). This gives us more control over what information we want to share with others—and who gets access.
3. A blockchain is resistant to modification of the data.
The blockchain is a digital ledger that records transactions in an immutable and shared manner. It’s decentralized and distributed, meaning it can’t be changed without the consensus of the network. This makes it resistant to modification of data, which is crucial for its security and transparency—and also enables other applications such as smart contracts (more on those later).
4. The blockchain concept allows information to be stored globally on thousands of servers.
It is a distributed database that records data across many computers, rather than just one. This means that instead of storing information on a single server, it’s stored in multiple locations and can be accessed by anyone with an internet connection.
Blockchain has several advantages over traditional databases:
- It’s permanent and transparent; no one needs to ask permission or pay fees to access it—you can see exactly what’s going on at any time (therefore making it resistant to manipulation).
- Transactions are recorded publicly and permanently so they cannot be modified later on; this prevents fraud because if someone tries to change something after the fact, everyone will know about it immediately!
5. Blockchain is mainly used for cryptocurrencies such as Bitcoin, Ethereum, and Litecoin.
This is a technology that makes it possible to store and exchange digital information. It’s been around since 2008, but it wasn’t until 2009 that Satoshi Nakamoto published the first bitcoin white paper, which introduced blockchain technology as we know it today.
Blockchain was made for cryptocurrencies like Bitcoin and Ethereum because they have no central authority controlling them. This means you can use your own money without having to trust anyone else or go through an intermediary (such as PayPal).

However, blockchain has applications beyond just cryptocurrencies—you can use this same technology for other purposes too!
6. Blockchain technology creates an opportunity to improve the world’s trade systems
Blockchain technology is still in its infancy, with major banks and governments still testing it. It’s not yet ready for mainstream use.
In the meantime, blockchain can help speed up international trade by increasing transparency and security through shared ledgers that are decentralized across multiple networks. Check out our CoinMasters News section to get the latest news on blockchain and cryptocurrency.
The blockchain revolution is changing the way we do business and make sure that everyone has access to information. The technology is becoming more popular, but it’s still too early for us to know exactly how much impact it will have on our lives in the long run.
