To be useful, solutions must use identifiers for people, but these may be generated IDs used only on-chain and useless off-chain, instead of sensitive PII elements such as name, Social Security number, date of birth, and so forth. Since a full copy of the ledger is presented each time a new transaction is added, as this information accumulates performance may degrade. Use cases and expected throughput requirements should be analyzed up front to ensure the platform and its consensus protocol have sufficiently high throughput and capacity to support the target use cases. Many blockchain-enabled solutions are growing to address the needs outlined in this legislation. The following architecture framework may be useful for constructing and evaluating solutions in healthcare. Each node synchronizes its copy of the shared ledger as consensus is achieved, according to the specific consensus protocol of that network, which is determined by the particular platform used to implement the network. This structure can include one or more than one member and should be detailed in legal agreements. The cipher can be exchanged by the sender and receiver. Having a clear idea of the problem that you are working to solve, what information and which stakeholders are needed to address the problem, and the expected result will shape these elements. Since they are essentially just code, they are still susceptible to zero day attacks and technical bugs. These networks allow for easier paths to demonstrate trust by validating all participants on the network. With P2P networks, since there is no central control, trust between nodes becomes an issue. In contrast, they are not intended for use only within a single organization. Cloud environments typically provide availability zones, load balancers, DDoS mitigations, and so forth that can be easily deployed, further simplifying and accelerating cloud deployment of nodes and enabling accelerated deployment of blockchain in healthcare organizations, thus improving their focus on the business or application layer, and evolving and improving their use of the technology. A public key represents the public identity of a user that can be shared with others. There are some technology considerations around blockchain in healthcare. This also has significant ramifications from a privacy, security, and compliance standpoint where a blockchain may contain sensitive information such as personally identifiable information (PII). Consortia must have robust governance to enable the success and evolution of the technology. Examples of identifiable information to keep off-chain also include data outlined in the Payment Card Industry and school health data regulated by the Family Education Rights and Privacy Act. It is important to understand these differences when considering blockchain in healthcare and if this technology is appropriate for your use case. It can also record a collection of code called smart contracts that enable functions to be run on the blockchain. However, for any enterprise systems that hold records referenced by the blockchain, it is important that such systems provide an externally accessible interface for retrieval of such information. The UAE Ministry of Health and Prevention announced their first blockchain in healthcare system to track health professional licenses, as part of this nationwide strategy. In instances where the data exchange is determined to meet the definition of specific data exchange (i.e., a transaction as defined in 45 CFR §160.103) under HIPAA, implementers will need to pursue the exception process identified (45 CFR §162.940) to mitigate any risk of non-compliance to the implementers. DLT leverages decentralized peer-to-peer computing, cryptography and related technology to verify and propagate a chain of transaction records across a consortium, alliance, partnership, or coalition.
