# How to apply blockchain By [sun](https://paragraph.com/@sun-2) ยท 2021-11-10 --- Public welfare field The data stored on the blockchain is highly reliable and cannot be tampered with. It is naturally suitable for social welfare scenarios. Relevant information in the public welfare process, such as donation projects, raising details, fund flow, recipient feedback, etc., can be stored on the blockchain, and can be made transparent and public conditionally to facilitate social supervision. Art industry Ascribe allows artists to use blockchain technology to declare ownership, issue numbered, limited edition works, and digital forms for any type of art. It even includes a trading market where artists can buy and sell through their websites without any intermediary services. Legal profession Bitproof is the most advanced of many document timestamp applications emerging in recent years, which will make the traditional notarization a thing of the past. Compared with free versions such as blocksgin and originstaemp, bitproof provides more services, including one for intellectual property rights. Interestingly, bitproof recently cooperated with an it school in San Francisco to put their students' academic certificates on the blockchain, completely redefining how to process and use diplomas and student certificates. Development industry Colu is the first enterprise to allow other enterprises to issue digital assets. Many people are impressed that they can "token" various assets. Although the free bitcoin wallet couparty also allows the issuance of simple tokens and transactions between other wallet holders, the tokens of colu can be set with various states and types, can be separated from or returned to the system, and can store data on BitTorrent's network when the data stored on the blockchain is too large. Real estate industry They plan to modernize the whole industrial chain process and solve various problems faced by everyone in participating in real estate, including naming process, land registration, agency, etc. Blockchain from a financial perspective The essence of money: money is only a broad consensus of value and does not have value precipitation itself. The relationship between assets and money: money describes assets. What is digital assets: assets are digital, subdivided and tradable, and the price is determined by the supply and demand market, rather than the value intermediary - currency. Internet of things Application scenario analysis One possible application scenario is: generate corresponding behavior through transaction, assign address to each device, inject a certain fee into the address, and perform relevant actions to achieve the application of the Internet of things. Similar to: PM2.5 monitoring point data acquisition, server leasing, webcam data call, DNS server, etc. In addition, with the increase of Internet of things devices and the enhancement of edge computing requirements, a large number of devices need to adopt distributed self-organizing management mode, and have high requirements for fault tolerance. The distributed and anti attack characteristics of blockchain can be well tried in this scenario. IBM has continuously invested in research and development in the field of Internet of things for decades and is exploring the use of blockchain technology to reduce the cost of Internet of things applications. At the beginning of 2015, IBM and Samsung announced the cooperative research and development of adept system. Logistics supply chain Supply chain industry often involves many entities, including logistics, capital flow and information flow. There are a lot of complex cooperation and communication between these entities. Under the traditional mode, different entities keep their own supply chain information, which is seriously lack of transparency, resulting in high time cost and money cost, and it is difficult to trace and deal with once there are problems (counterfeiting, goods counterfeiting, etc.). Through the blockchain, all parties can obtain a transparent and reliable unified information platform, which can view the status in real time, reduce logistics costs, and trace the whole process of production and transportation of goods, so as to improve the efficiency of supply chain management. When a dispute occurs, the proof and tracing become clearer and easier. This field is considered as a promising application direction of blockchain. For example, the carrier can scan the QR code to prove that the goods arrive at the designated area and automatically charge the fees agreed in advance. You can refer to how the blockchain changes the supply chain finance and the blockchain to bring transparency to the supply chain --- *Originally published on [sun](https://paragraph.com/@sun-2/how-to-apply-blockchain)*
