Last week we had a pretty in depth update, so this week we’re going to keep it short and mostly technical.
New Alchemy development team is visiting our London office from July
17–21 to coordinate on the next phases of the project and also to
finalize components the UI/UX. We’re excited to be able to sit down and
get their input in person.
We’re also meeting up with the Wavecrest team next week to discuss different options for card issuance roll out.

Healthcare: Re-engineered and Powered by Patientory
ransomware cyber-attacks have exposed a vulnerable global healthcare IT
infrastructure. Personal Health Information data is at risk.
Unfortunately, legacy systems now administrate Personal Health
Information (PHI) across siloed database networks. Fragmented Electronic
Medical Records (EMR) create cumbersome access points and data
exchanges are fraught with friction. Patientory is a patient-centered
enterprise solution designed to eliminate many of these pain points.
uses blockchain technologies to ensure end-to-end encryption while
adhering to region-specific regulatory guidelines and compliance
requirements. Our solution design uses encrypted middleware to meet the
high-volume demands of modern day HealthcareIT. Ultimately, Patientory
empowers patients, clinical care teams, and insurance providers to
overcome many challenges faced within current decentralized
goal of this post is to provide insights to our platform architecture.
This post assumes general knowledge of hardware security models,
identity platforms, cloud computing and enclaves (secure elements).
Introducing the Middle-Tier to Blockchain
of the early challenges developing blockchain proof of concepts (POCs)
for the enterprise revolved around two prominent concerns: scaling and
privacy. In addition, the limited two-tiered architecture
(client/server) presents version control issues and is difficult for
in-house IT teams to implement. Poor key management also is also
catastrophic for early adopters.
time and a maturation of the technology, however, has come evolution
and the use of a middle-tier in blockchain architecture. This has
enabled in-house teams to develop application functionality and feature
sets using familiar tools and languages. This multilevel framework
provides a separation of concerns (middleware) similar to modern web
infrastructures. The middle layer allows the platform to interface with
existing systems and scale more efficiently off-the-chain. The business
logic (smart contracts) flows securely on and off the blockchain.
How Does Patientory Fit Into the Picture?
creates, configures, and query blockchain-enabled smart contracts that
leverage both “traditional” cloud middleware and new application
services to support blockchain development for nodes on and off the
chain. Within this framework, the implementation of modern application
services like biometrics and OAuth, real-time data and billing, and
personal health insurance information are now possible. Applications can
be developed using standard development tools, reducing time-consuming
learning curves for onboarding and implementation.
Data applications on the Patientory platform is also implemented and
executed more expeditiously a with three-tiered architecture. Using this
framework, our roadmap can expand to include ingesting Big Data from
multiple sources. Harnessing this data will unearth valuable insights
for clinical care teams, as well as healthcare intelligence with
actionable analytics for better patient outcomes.
How We Envision the Patientory Framework
Please see the infographic below for an illustration of the Patientory framework.
First, we start with the presentation layer. This
is the user touchpoint for accessing their healthcare information in
real time. Prescription adherence alerts, wearables data, Explanation of
Benefits (EOB), and real-time data can be found here. Hospitals,
Clinical Care providers and other enterprise members interface here as
well exchanging information securely in the P2P network.Second
tier: Middleware. Oracles execute in a secure computational
environment, and have the cryptographic primitives that allow them to
work directly with blockchains. On the platform, business logic executes
in a fabric that binds the code to a smart contract. Identity and key
management, cryptographic,services,attested data and interaction with
the outside world runs in this secure environment.Third tier: Data Layer and Schema. This
third layer serves as a distributed database of the shared truth
between nodes on the blockchain. The ledger is an instantiation of a
version specific contract between several different parties. Smart
contracts are bound by the ledger, schema, counterparties, logic, and
external sources. The platform is fully auditable and can serve to
automate many healthcare operational processes.
are confident that Patientory helps move HealthcareIT into the future.
It’s not only long overdue, but the increasing amount of ransomware
incidents demands it. Let me know if you feel the same.
