“…A few other types of blockchains are also found in the research prototypes. Quorum [249] (which is based on an Ethereum core) is used by electronic health records sharing system [107] and vehicle life-cycle data sharing [151] because of its integrated support for private transactions. The ARK [250] blockchain was selected to record higher education course credits records [81] due to its flexibility in the number of programming languages its client implementations support.…”

Blockchain for Cities—A Systematic Literature Review

2018

Blockchain is considered one of the most disruptive technologies of our time. Numerous cities around the world are launching blockchain initiatives as part of the overall efforts toward shaping the urban future. However, the infancy stage of the blockchain industry leads to a severe gap between the knowledge we have and the actions urban policy makers are taking. This paper is an effort to narrow this rift. We provide a systematic literature review on concrete blockchain use cases proposed by the research community. At the macro-level, we discuss and organize use cases from 159 selected papers into nine sectors recognized as crucial for sustainable and smart urban future. At the micro-level, we identify a component-based framework and analyze the design and prototypes of blockchain systems studied in a subset of 71 papers. The high-level use case review allows us to illustrate the relationship between them and the four pillars of urban sustainability: social, economic, environmental, and governmental. The system level analysis helps us highlight interesting inconsistencies between well-known blockchain applicability decision rules and the approaches taken by the literature. We also offer two classification methodologies for blockchain use cases and elaborate on how they can be applied to stimulate cross-sector insights in the blockchain knowledge domain.INDEX TERMS Bitcoin, blockchain, computer networks, consensus, crypto token, distributed computing, Ethereum, Hyperledger Fabric, systematic literature review, smart city, smart contract, system analysis and design, peer-to-peer computing, urban sustainability, use case.

“…So a private blockchain might be a better choice for our system. 4) Incentive: Like in [21], we do not include any incentive for mining beyond the use of our system. We presume that all nodes on the blockchain already have incentives to keep medical data from being illegal access or updates.…”

Electronic medical data sharing between stakeholders, such as patients, doctors, and researchers, can promote more effective medical treatment collaboratively. These sensitive and private data should only be accessed by authorized users. Given a total medical data, users may care about parts of them and other unrelated information might interfere with the user-interested data search and increase the risk of exposure. Besides accessing these data, users may want to update them and propagate to other sharing peers so that all peers keep identical data after each update. To satisfy these requirements, in this paper we propose a medical data sharing architecture that addresses the permission control using smart contracts on blockchain and splits data into fined-grained pieces shared with different peers then synchronize full data and these pieces with bidirectional transformations. Medical data reside on each user's local database and permissionrelated data are stored on smart contracts. Only all peers have gained the newest shared data after updates can they start to do next operations on it, which are enforced by smart contracts. Blockchain-based immutable shared ledge enables users to trace data updates history. This paper can provide a new perspective to view full medical data as different slices to be shared with various peers but consistency after updates between them are still promised, which can protect privacy and improve data search efficiency.

Keamanan Data Rekam Medis Memanfaatkan Multi-Block Type Blockchain Pada Jaringan Terdistribusi

Saat ini rekam medis telah banyak diterapkan baik secara konvensional maupun elektronik. Rekam medis elektronik telah menjadi keharusan dalam pencatatan sejarah kondisi kesehatan bagi setiap pasien. Pencatatan ini melibatkan instansi pelayanan kesehatan, para petugas kesehatan, apoteker, dan pasien. Karena telah banyaknya rekaman yang telah dibuat serta penanganannya yang kurang memadai maka timbullah berbagai masalah. Masalah yang sering muncul adalah keamanan dari rekaman itu sendiri dari berbagai pihak yang dapat menyalahgunakan. Ini akan sangat berdampak pada semua yang terlibat utamanya pada pasien. Pasien akan mendapatkan kerugian besar baik materil, psikis, dan kerugian sosial. Beberapa solusi telah diusulkan seperti pencatatan terpusat, penerapan enkripsi, verifikasi berulang. Solusi terbaru berupa penerapan pencatatan terdistribusi dan memanfaatkan enkripsi data yang disebut blockchain. Pada usulan ini, block data dibuat dengan berbagai tipe yang diterapkan pada blockchain transaksi rekam medis pasien. Proses ini menerapkan smart contract antar pihak yang diregulasi oleh pemerintah. Kontrak tersebut diterapkan dan memakai block data yang berbeda-beda sesuai dengan kebutuhannya. Tipe-tipe block yang disediakan berbeda-beda sesuai dengan kebutuhan akses dari penggunanya. Keamanan adalah alasan utama sehingga pengelolaan melibatkan pemerintah, penyedia layanan kesehatan, apotik, petugas kesehatan, asuransi, dan pasien. Penglibatan secara menyeluruh ini untuk meningkatkan keamanan ke yang paling optimal. Pencatatan menerapkan enkripsi yang bertingkat dan bersambung antar rekaman sehingga membentuk rantai rekaman. Rantai rekaman selanjutnya didistribusikan ke seluruh pihak. Hal tersebut dapat mencegah data untuk diubah sehingga menjaga keamanan data rekam medis. Perubahan data hanya dapat dilakukan dengan persetujuan dari pasien dan diketahui seluruh pihak yang terlibat. Solusi ini dapat memberikan keamanan dalam hal konsistensi data, immutable, privasi pasien dan keadilan informasi bagi seluruh pihak.
