The development of blockchain technology creates extremely hot career development opportunities for programmers pursuing this field. So what is blockchain?
What is Blockchain?
What is Blockchain?
What is Blockchain? This is a block – chain technology that allows us to securely and quickly transmit and store information on a complex cryptographic system. In simple terms, Blockchain has the same function as the accounting ledger of businesses.
Blockchain is a new technology that improves the limitations of traditional information storage and exchange. For this reason, blockchain is increasingly being applied widely in many socio-economic fields: finance, education, agriculture, industry, entertainment, and health…
The outstanding advantages of Blockchain technology
What is Blockchain?
- High security: Once the data is updated in the system, it is very difficult to forge and modify, as this information will be shared and verified by millions of computers in the network.
- Data is not lost: In a blockchain network if one computer goes down, the data on it is not lost at all because other computers in that system already own a copy of the ledger.
- Cross-border transactions: Blockchain technology helps limit human involvement in the processing, which facilitates cross-border transactions that are not affected by time zones and occur without the interference of an intermediary.
- Ensure transparency: No one can tamper with the blockchain network thanks to the transparency and audibility of this technology. Therefore, this advantage is used by many organizations to combat money laundering.
- Cost savings: This is also one of the most noticeable advantages of putting blockchain technology into practice. It will cut unnecessary verification processes, reduce errors, and reduce the burden of traditional paper storage.
- Minimize transaction processing delays: The traditional banking system usually takes many days to process the data. This is why banks need to regularly update their systems. However, blockchain can completely handle this problem because it processes data at a very fast speed. This advantage helps banks save a lot of time and money and brings convenience to their customers.
What is Blockchain & The potential market of blockchain in 2023
What is Blockchain? The potential market of blockchain in 2023
Blockchain technology, which has appeared in recent years, has brought many new opportunities and new solutions for data management and transaction security to many fields.
However, the crypto crisis in 2022, starting with the collapse of the Terra Luna and FTX ecosystems, has led people to question the future of blockchain as the technology is at the present time. is still known to be associated with the cryptocurrency market.
Despite this, blockchain is still a technology that plays an important role in many fields and industries. In the financial services sector, for example, cross-border money transfers must go through the Society for Worldwide Interbank Financial Communications (SWIFT). But SWIFT only focuses on processing payment orders, while the actual money is transferred through the intermediary system, which increases additional costs and increases the working time from 2–4 days. If blockchain technology is applied, money transfers can be made directly and tracked openly and transparently without having to rely on SWIFT or any other intermediary.
In terms of traceability, blockchain technology is being widely applied to encrypt information about products. Users can easily use the encrypted serial number to look up product information.
Although 2022 is considered a challenging year in the blockchain field, experts say that if companies apply Web3, it can help end the “crypto winter” earlier, and the future of this blockchain technology will be very bright as it has the potential to change many industries with transparent and secure transactions.
The first is AI (artificial intelligence), and with the introduction of ChatGPT, these two factors are expected to create many surprises if combined harmoniously. AI uses machine learning to drive the performance, efficiency, and accuracy of data, while blockchain seeks the power and energy to run a network of computers.
Second, Defi 2.0 is a term used to refer to decentralized finance. This is a new development of Defi with more improvements and more applications. It helps people access, access, and use financial applications anywhere, anytime, without being influenced by individuals or organizations that concentrate power.
Finally, with the strong development of these platforms, many retail investors have been able to access safe “staking” products with better interest rates than banks and the potential for price increases in the future. This will continue to attract new investors’ cash flow into the market.
