Applying Blockchain Technology and Smart Contract Technology in Business

How decentralization can change the world

Blockchain is the buzzword of this generation that will trigger a new wealth revolution

Why need this technology

The emergence of blockchain technology has brought tremendous changes to wealth generation! Cryptocurrency should be the most widely recognized application of blockchain technology. Its decentralized structure has completely subverted the operation mode of traditional currencies.

Recently, there is more attention on blockchain technology because of its “decentralized” nature. Data recorded on a blockchain cannot be tampered with, reducing errors and fraud. It is a revolutionary technology that can completely change business operations. It can be used to write “Smart Contracts” to replace traditional paper contracts. As long as certain conditions are met, the computer will automatically execute the contract terms. Blockchain technology also has application in different sectors, including medical and logistics. Blockchain technology is definitely a new trend worthy to be mastered!

Pain Points We Solved

Although the term blockchain has been heatedly discussed in the fintech community, there are few commercial applications of blockchain technology. The main reason is that people do not have a good understanding of its operating mechanism and technology.

Many people mistakenly think that investing in virtual currency is all that blockchain is; companies do not know that part of their business can be improved through blockchain technology, investing blindly and missing out on an opportunity to improve. Presently, information about blockchain in the market is too scattered, and the application of this technology in the business community is still at an initial stage. With this course, we hope to accelerate the application of blockchain in business!

Programme Highlights

This course is taught by seasoned IT industry instructors and will cover the basic knowledge of blockchain technology, including its principles, history and development, virtual currencies, including Bitcoin and Ethereum, and extended business applications, such as Smart Contract. The instructor has experience in developing blockchain applications for international companies. The class will strike a balance between theory and practice. In addition to teaching blockchain knowledge, students will have the opportunity to write smart contracts by themselves and experience the potential of blockchain technology.

The pain point of the logistics industry is to deal with different companies in the supply chain, such as production plants, warehouse, airlines, transportation companies, etc. If the tracking and transparency of the entire supply chain can be strengthened, it will surely save cost for all parties. Blockchain technology operates in a decentralized form, which can reduce the chances of errors and fraud. At the same time, smart contracts can increase the trustworthiness of the parties involved. I look forward to the changes that blockchain technology will bring to the logistics industry!

Case Study

Blockchain technology protects personal data

Protecting the personal data of patients is a major issue that the healthcare industry has to handle with care.
At present, patient data, such as medical history, medical records, and personal data, are mostly stored in the database of a single hospital or medical institution. There are three risks: data leakage, data being damaged or deleted, and difficulty in transfer of medical records. The emergence of blockchain technology can be a safe and effective solution for data storage and protection.
The characteristic of the blockchain is that once the information is entered into the blockchain, it cannot be modified. Meanwhile, patients can authorize access by different institutions. This is an ideal tool that can greatly protect the privacy of patients and improve the circulation of medical information!

What is blockchain? Can you explain it in laymen terms?

You can imagine that there are many computers connecting to a network, each with its own ledger. When you want to record a transaction, e.g. when someone borrows money from you, all the computers in the network keep a record of the transaction at the same time. The first block is thus created. When the loan is paid back to you, this repayment record becomes another “block” that is connected to the first block, and with cryptographic methods new blocks can only be connected to earlier blocks chronologically. No one can access the information without authorization and the information cannot be altered. You can also use blockchain to set up a “smart contract” to automatically receive repayment monthly. Compared to only saving data in one computer, isn’t this blockchain method more reliable?

Is there any practical application of blockchain in Hong Kong?

At present, insurance companies have launched mobile applications that use blockchain to manage customer insurance policies.
The Financial Services and the Treasury Bureau of the HKSAR Government issued a report on 1 June 2020, stating that a total of 57 new FinTech companies was established in Hong Kong last year. Among them were companies specializing in the field of blockchain and distributed ledger technology (DLT). The growth is evident, accounting for 39% of the new FinTech companies, which is higher than the 27% in 2018.

Our company has no experience in using ecommerce, let alone blockchain technology.  Will this course be too advanced for us?
