How blockchain works
Blockchain works by recording each transaction as a block of data. These blocks are connected to a previous and a subsequent block, forming a data chain.
Transactions are included in an irreversible chain, strengthening verification of each block and the entire chain. In this way, blockchain offers immutability and eliminates the possibility of tampering by a malicious individual.
Blockchain components:
- Transactions: Transactions are the information that will be recorded on the blockchain, such as the transfer of digital assets.
- Blocks: Blocks are sets of transactions that are grouped together and added to the existing blockchain.
- Hash: The hash is a unique sequence of characters generated from the data contained in a block. It serves to identify and verify the integrity of the block.
- Miners: Miners are responsible for validating transactions and adding new blocks to the chain. They compete to solve complex mathematical problems that require computational power and are rewarded with cryptocurrencies such as Bitcoin.

What is Blockchain?
Blockchain can be defined as a block chain, which groups a set of information connected through encryption. It is important to ensure the security and integrity of transactions, and works like a large public ledger, in which all transactions are recorded. Blockchain allows transactions to be carried out securely, making each currency traceable from the moment of its creation.
Blockchain is an innovative technology that is revolutionizing different sectors in the world. Brazil and in the world. It offers solutions to trust and security issues, creating an environment conducive to new business opportunities.
The blockchain is like a large public ledger, immutable and decentralized, which records all transactions in a transparent and secure way.
This distributed ledger ensures that all parties involved have access to the same information and avoids the need for intermediaries to validate transactions. Furthermore, blockchain uses cryptography to protect data and guarantee its integrity.
With blockchain, each transaction carried out is grouped into a block and connected to other previous and subsequent blocks, forming a chain of blocks. This structure guarantees the security and reliability of transactions, making blockchain an ideal technology for various applications.
Main features of blockchain:
- Decentralization: there is no central entity controlling the network, making it more secure and resistant to attacks.
- Transparency: all transactions are publicly recorded and can be audited in real time.
- Immutability: Once a transaction is recorded on the blockchain, it becomes permanent and cannot be changed or reversed.
Blockchain technology is transforming several sectors, from finance to healthcare and logistics. It offers solutions to problems such as fraud, lack of transparency and unnecessary intermediaries, providing greater efficiency and security in transactions.
How does Blockchain work?
Blockchain is a technology that orders blocks of information in a sequential chain, ensuring the security and reliability of transactions. Each block contains essential data, such as the date and time it was mined, the amount transacted, parts of the transaction and unique hashes.
Miners play a fundamental role in the process, being responsible for finding solutions (hashes) that connect blocks and validate transactions. After mining a block, users of the Bitcoin network check the answer provided by miners and decide which sequence of blocks to follow, opting for the longest and most reliable chain.
See below for a visual representation of how it works the Blockchain:
| Blockchain Components | Operation |
|---|---|
| Date and time | Records the date and time the block was mined, creating a sequential history of transactions. |
| Quantity Transacted | Records the amount of value transacted in each block, ensuring transparency in financial transactions. |
| Parties to the Transaction | Records the parties involved in each transaction, allowing verification and traceability of operations. |
| Unique Hashes | It uses cryptographic hashes to interconnect blocks, making it impossible to change past data and maintaining the integrity of the chain. |
Through this process, Blockchain guarantees the security of transactions by eliminating dependence on a central authority. Additionally, the immutability of records provides an additional layer of reliability, making Blockchain a promising technology for diverse industries such as finance, supply chain, healthcare, and more.
