About Client:

There are numerous risks/challenges that are associated with Modern Healthcare. Due to globalization and the involvement of many intermediaries, Healthcare Process is becoming more and more complex, which is impacting the companies vision of enhancing efficiency, operational cost reduction.
Following are the main causes of the risks and challenges in Healthcare and associated Blockchain Solutions:

  • Fragmented Data
  • Timely Access to Patient Data
  • System Interoperability Data Security
  • Patient Generated Data
  • Access and Data Inconsistency
  • Cost Effectiveness

Problem Statement:

Bank wants to track Secure Loan – Savings Account as collateral pledge tracking using Blockchain
They want any collateral booked on their collateral system should be available as an externally consumable Webservice
The objective is to track each collateral as a digital asset since the origination, trail of records and should act as a single source of truth of collateral on the blockchain network.
For an update on the collateral like pre-payment of a loan amount, an event triggered from the collateral system and the smart contract would capture the event and log the transaction on ethereum blockchain. This would help manage any constraints on the collateral on the blockchain network to maintain 100% transparency with the customers

Our Solution:

DreamzChain developed Solidity smart contracts to interface with bank collateral system, Smart contract handle events and oracles to query external services Ethereum solidity smart contracts fetch the collateral information from the Webservice using Oracles. The contract was developed keeping in mind optimization for minimum gas consumption web3.js & other JavaScript frameworks used to interface with solidity contracts and develop the UI Ropsten test net along with Metamask used for testing the smart contracts. An overall solution would be tracing the end-to-end lifecycle of collateral Created a mechanism to secure transaction for Hardware Wallet Email notification to the Loan Representative and Customer once the loan Balance reaches zero

Benefits

Single source of Truth of collaterals
The bank is able to trace end-to-end lifecycle of Collateral
Real-time collateral reconciliation
Transparency and visibility to the customer of the outstanding loan balance
Immutable ledger of all loan transactions pertaining to savings and CD accounts
Real-time alert and notification when loan fully repaid
Synchronization and reconciliation between the blockchain network and banking internal systems
Increase efficiencies in banking processes
Improved customer satisfaction

Blockchain Healthcare Solution Steps:

HOW DREAMCARE PLATFORM CAN HELP YOU TO DESIGN CUSTOM HEALTHCARE SOLUTIONS

  • Close collaboration between patients and providers is a fundamental requirement for value-based healthcare, yet many healthcare organizations struggle to break down their data and exchange information in a secure and timely manner.

  • Blockchain can be a viable solution to help healthcare organizations leap over those hurdles while keeping the patient at the center.

  • In order to provide services that fall in line with value-based healthcare, one has to be able to access that comprehensive, trusted view of the patient.

  • Everyone has their own health data repositories and their own electronic health records – the proposal here is not to replace those existing systems but to supplement them with new exchange capabilities.

  • If Healthcare organizations want to increase the fluidity of data between different institutions, they can connect their existing repositories to the blockchain and improve the movement of data by keeping patient’s desires in mind.

  • Patients are in an excellent position to take charge of this process.

  • Administrative tasks such as claims processing and underwriting may also benefit from a blockchain approach since managed permissions make it easier for patients to assess the validity of a claim, manage pre-authorizations, and ensure that providers are meeting the criteria laid out in their value-based contracts.

  • Smart contracts could automate these processes and decrease the time and resources needed to execute the terms and conditions of value-based contracting. And because smart contracts are decentralized and cannot be changed, all parties can be confident that terms will be consistently executed.

  • Patients may also be able to better personalize their member offerings and improve the patient experience by reducing the friction, stress, and frustration often associated with managing insurance issues.

  • Instant and validated acquisition of patient-generated health data and information from all of an individual’s providers will help create tailored incentive programs, conduct more proactive outreach, and issue reminders that aid in chronic disease management.

  • Instead of interacting with their health insurance only when paying premiums or addressing illness or injury, consumers could develop a positive relationship with their carrier.

  • If exercise and staying active results in immediate and tangible benefits, such as discounts on premiums or reduced deductibles, consumers could associate health insurance with wellness and benefits instead of illness and medical expenses.

FEW OF THE BLOCKCHAIN USE CASES

Patient’s data over a Blockchain

Health organizations direct information to the blockchain

Health organizations
can provide better services to patients. Currently, Clinical data is tracked in existing health IT systems. Standard data fields and a patient’s public ID can be redirected to the blockchain via APIs.

Transactions are completed and uniquely identified

Each transaction can be stored on the blockchain, containing the patient’s public (non- identifiable) ID Smart contract processes incoming transactions.

Health organizations and institutions can directly query the blockchain

Health organizations and institutions submit their queries via APIs. Non-identifiable patient information (e.g. age, gender, illness) is viewable. Data can be analyzed to uncover new insights.

Patients can share their identity with health organizations

The patient’s private key links their identity to blockchain data. The private key can be shared with new health organizations. With the key, organizations can then uncover the patient’s data. Data remains non identifiable to those without the key
