On October 24th, 2018, South Korea time, Prof. Haogang Zhu, Member of Advisory Board, E-Goverment Committee, China, was invited to attend the Regional Symposium on ‘Strengthening Capacities of Public Institutions and Developing Effective Partnerships to Realize the 2030 Agenda for Sustainable Development’. The regional symposium was jointly sponsored by United Nations Department of Economic and Social Affairs and Incheon Metropolitan City Ministry of Interior and Safety. Prof. Haogang Zhu introduced ‘Leben’, the medical smart contract operation platform, for the first time in public as the experience to extend the capacity of healthcare public service.
Prof. Haogang Zhu was giving a speech
Leben is a global medical industry smart contract collaboration platform featuring “deep sharing of medical knowledge” and “trusted exchange of medical data”, and integrating medical artificial intelligence and blockchain technology. With the vision of promoting “global medical homogenization”, Leben creates a disruptive value system of the medical industry, clearly defines the three main value carriers (knowledge, data, and computing power), and proposes a “Projection of Thought” system to spread out the ontology cognition and the digital world conversion channel. Based on the blockchain and smart contract technology, Leben builds a value mobile platform and designs a “dual track” monetary economy system, expands medical value series, so as to provide energy for all links of the medical industry chain. Thus, a continuously flowing and expanding economic cycle system is established thanks to Leben. Around the multiple-links and multiple parties, Leben also establishes a complete ecosystem including empowerment ecological layers and innovation ecological layers to form an ecological gravitation, and promotes the new models and new forms of business operation for the transformation and upgrading of the medical industry. Leben further proposes an open, transparent, efficient and sustainable development governance system to ensure the reasonableness and justice of multi-party’s interests and support its efficient and stable operation.
The birth and development of Leben project not only provide a new platform for the construction of the credit system in the medical industry, but reshape the medical knowledge acquisition & optimization methods, data exchange and sharing channels, so that every participant on the platform becomes a platform through collaboration. Innovation and real-world practices promote the development of the global medical system quickly, and provide more momentum for the improvement of the well-being of all humankind.

Prof. Haogang Zhu is a research scientist at University College London and an honorary research scientist at Moorfields Ophthalmological Hospital. He was awarded a research scientist title by the National Institutes of Health of the British Ministry of Health, and has become the Secretary-General of the China Blockchain Technology Innovation and Application Alliance. He is the chief architect and one of the initiators of Leben. He said: ‘I was a research scientist in AI medicine having been working in various diseases, such as heart disease, congenital heart disease as well as cerebral stroke. The problem I find is that the difficulty is not always on the training of the AI model but instead is the accumulation or the acquisition of the data. The quality of data from the hospital in general is pretty poor and to get the data out of the hospital in a regulated and ethical way is very difficult. So in general, the cost of data is very high which prevents the artificial intelligence technology to be used in hospitals. Another problem is that when we have the AI products and want to deploy them in the hospital, we always adopt a centralized data system for that, which will bring difficulties for hospitals to share or transfer their data, preventing the AI to be deployed in the end. From that point of view, my research direction has been switched to how we can share the data in a more trusted way, so that we can get more data out of each participant in a more effective and low-cost way to make the AI be trained more efficiently. The original intention for Leben is to exchange the data, the computing power, as well as the knowledge so that the three resources do not have to be in one place. Our collaborative computing architecture will be able to compute the data from one institute using the algorithm or knowledge from the third party. And that type of architecture will be able to help us to establish the framework of exchanging and even trading three types of resources.”

Another initiator of Leben was Dr. John Fox, professor at Lincoln College and School of Engineering Science at Oxford University, co-founder and chairman of OpenClinical Technology Services. As the chief scientist of the Leben, he brought a complete set of medical AI algorithm languages. He said: ‘Leben will not only empower the delivery of the services in many countries, in many circumstances, but also help healthcare professionals improve the quality of what they can offer to their patients. And patients pretty increasingly can look after themselves.’

At present, Leben has several DApps with specific medical application scenarios, such as CHDr., Stroke Dr. and so on. Most of them are in the direction of ‘clinical assistant diagnosis and treatment’. Now the official website of Leben has been launched and the first edition of the white paper is online.
