In this article, Lina Network will provide an overview of new Blockchain technology based on the understanding and aggregation of information from Blockchain documents, and introduce practical applications of today’s technology. to solve problems in life. The article is also assumed that readers have a basic  understanding of Blockchain technology. Therefore, we only introduce the overview of Blockchain, except for the technical aspects of this technology.

Overview of Blockchain

Blockchain is a shared digital ledger. This ledger is shared for network participants, which aims that in the whole system and there is not only one location, a document can serve as a single reliable basis, because duplicates of the same version of the ledger are also located in other places.

The practical application of Blockchain

Applying in Financial Services

Blockchain technology is used in both domestic and international money transfers. However, in some countries there are laws against blockchain money transfers, as they have invested a lot in existing centralized solutions, but in the near future, the world would benefit greatly from the shift from centralized systems to decentralized solutions on the Blockchain platform.

Applying in Healthcare

The healthcare sector will benefit greatly from blockchain technology due to security, privacy, security and decentralization. However, the Electronic Health Records (EHR) system faces issues related to security, integrity and data management. Since EHR is built on the Blockchain platform, resolving shortcomings in the current EHR system. Blockchain-based EHR allows patients to own their own medical records and can share them with health facilities, clinics, and hospitals when needed; avoid re-testing many times due to inaccessible access to old medical records.

In the future, fintech scientists say that you will be able to use a digital ID to register at any registrar.

This technology has a potential to bring many positive changes to supply chain management across all industries. A number of companies like Walmart have used IBM’s Supply chain based on Blockchain platform to track the origin of their products.
