Blockchain refers to distributed electronic databases shared on public or private networks. Briefly explaining how blockchain works, sharing all database transactions among multiple users allows each user to verify the correctness of the database and prevent the execution of malicious transactions.

Blockchain was originally developed about 10 years ago as a major component of digital currencies such as Bitcoin, but the scope of this technology goes beyond financial transactions. If you want to protect your critical data from security threats and ensure its integrity, blockchain is a powerful choice.

Blockchain can streamline the process and eliminate intervening third parties, enabling you to share business-critical, sensitive, and personal information faster and at a lower cost. It also produces a clear digital trail of transactions so that you can audit the trail to see exactly what happened on your network.

In this way, blockchain technology makes it easy to keep provable digital records. You can try bitcoin trading through, including financial transactions, processes, tasks, contracts, etc., so that your business is always based on accurate and reliable data. Enables decision making.

The advantage of blockchain is not only that there is no limit to the amount of data that can be stored. The data once recorded on the blockchain cannot be changed and it is almost impossible to tamper with or hack.

As a result, business operations based on the blockchain can eliminate operational waste and increase efficiency without sacrificing speed, customer experience, network visibility, or security.

For this reason, blockchain is drawing attention from companies as a means to solve various issues related to quality assurance, accounting, contract management, supply chain management, data protection, etc. Blockchain has the potential to drive cost savings, improve customer service quality, and comprehensive efficiency, regardless of industry.

To get a good understanding of blockchain technology, the following introduces how the blockchain system works, how to protect important data, and how to choose the most suitable tool.

What is blockchain technology?

The blockchain technology that records and synchronizes transactions on multiple independent nodes. To understand blockchain technology, let’s first focus on its name.

Block word is means to a digital record of a particular online transaction. “Chain” refers to a distributed database of many networked computers and devices. All these computers and devices act as one public ledger that collects and records blocks.  A large blockchain ledger consists of thousands of computers and millions of computers and devices such as Bitcoin. Small blockchains can only consist of devices within a single organization.

The blocks in the chain can be thousands or even millions in length, but they all come from a single transaction. Each time someone makes a transaction (such as shopping online), a block is created in your digital ledger that records details such as the date and time, the asset (amount) traded, and the digital signature of the person or organization that performed the transaction.

One of the key features of the blockchain is that when recording a transaction, no identity information (such as the buyer’s name) is recorded. Instead, a hash or digital signature is applied to each transaction. This unique mechanism is important in ensuring both the privacy and security of blockchain data.

Each block also contains a pointer to the previous block in the blockchain ledger. This pointer connects blocks. In this way, a new block is created each time a transaction occurs and the chain of blocks grows.

Once a block is chained, the data in the block in front of it cannot be modified or deleted by anyone, even the system administrator. In other words, blockchain creates a data chain with almost perfect tamper resistance. So blockchain lets you go back in time and see the exact state of all transactions as they happened.

Blockchain: Mechanism and details

What is a blockchain transaction?

The difference between blockchain transactions and other types of online transactions is that data is replicated, stored, and validated across multiple devices, rather than being managed by one centralized administrator.

As soon as a user requests a transaction, the details of that transaction are simultaneously broadcast to all devices in the network. Then within seconds, each device verifies its details and communicates with each other whether the transaction was confirmed.
