As well, the blockchain-based digital ID system will help get consent from patients on the use of protected healthcare information (PHI).

Together, capabilities unlocked by MedAwatar’s blockchain-based ID system will enhance compliance with laws and standards that protect sensitive patient health information from being misused.

Take the case of the Health Insurance Portability and Accountability (HIPAA) -- a set of standards that guarantee the security of protected health information, ensuring the availability, confidentiality and integrity of individual health information while also granting access to healthcare providers, clearing houses, and other health-related businesses.

Through a unique and blockchain-based architecture, MedAwatar will integrate safeguards that protect against PHI losses, prioritize patient well-being, facilitate the development of patient-centric healthcare cultures, reduce HIPAA-related liabilities, and improve patient satisfaction scores. This will improve how healthcare providers in India (and in the future, other countries) interact with and derive benefits from protected health information.

Compliance with laws and standards touching on patient information, through the Plugin-enabled Medawatar, will help healthcare facilities manage PHI-related risks and take precautions to avoid associated penalties. This is important in maximizing operational efficiencies and profits in today’s healthcare

2. Convenience
Leveraging the XDC network and Plugin’s oracle network, MedAwatar’s users will have a robust, secure and easily accessible digital health platform. Through the platform, patients and healthcare providers can benefit from ease of communication, ease of remodeling patient-doctor relations, and the improved treatment outcomes.

To elaborate, doctors will easily access patient records via the MedAwatar platform, allowing them to have a deeper understanding of a patient’s treatment history. With a deeper insight into a patient’s condition, doctors and other caregivers will connect easily with patients. And in some cases allow patients to contribute to the development of their treatment plans.

Convenient access to patients’ health statuses will go a long way in building patient-physician trust, helping maintain transparency in the patient-doctor relationship. With accurate and real-time data, MedAwatar will help doctors make exceptional decisions that’ll go into improving a patient’s treatment outcomes. Some of these decisions may include recommending changes in diet, lifestyle, or treatment plans.

Over time, convenience, that’s associated with the blockchain-based healthcare platform, will introduce numerous benefits, improving the quality of healthcare in India and other nations.

3. Scalability

Offering a highly scalable MedAwatar will unlock important benefits for healthcare facilities. Particularly, the scalable solution will allow smaller healthcare facilities to cater for its client’s current needs while preparing for future growth, and reduce expenses incurred during upgrade and training updates for staff.

On the other hand, a scalable MedAwatar will avail clients with a variety of features in addition to securing protected health information and generating unique and blockchain-based ID. These features will help patients have a better experience with the entire healthcare continuum.

4. Improving Workflows
Studies have shown that inefficient clinical workflows in healthcare result in considerable waste in today’s healthcare. However, the introduction of robust digital health platforms has the potential to improve workflows, cutting losses associated with inefficiencies.

In this light, the inception of an XDC-based and Plugin-powered enterprise-level application through the Plugin--Awatarpay partnership will be a game changer in improving workflows.

To elaborate, MedAwatar’s appointment scheduling will play a key role in improving healthcare workflows in Indian hospitals. Particularly, MedAwatar’s appointment scheduling will help automate patient scheduling and the gathering of important information to help doctors prepare for appointments. By employing Plugin’s reliable data protection protocols, MedAwatar will easily employ tools like appointment reminders, pre-visit instructions, patient education, electronic intake forms, surveys, and other message touchpoints to ensure patients arrive for care on time and prepared. This will help healthcare providers to fill informational gaps and plan their workflows in advance.

Eventually, improved workflows will help improve the efficiency of Indian facilities, enhancing treatment outcomes and increasing the utility of healthcare resources in the care continuum.

5. Eliminating No-shows and Resulting Costs
Patients not attending doctor’s appointments (also referred to as no-shows) significantly affect the cost of care and resource planning within today’s healthcare setup. No shows also lead to loss of anticipated revenue, particularly for healthcare services that are expensive and in high demand.

That said, MedAwatar’s automated appointment scheduling service will use verified data from Plugin to develop configurable appointment reminders. These will ensure that patients get notified of scheduled appointments and informed of different requirements prior to their arrival. As well, the system will integrate communication touchpoints on portable devices, which will help boost communication between patients and healthcare practitioners, prior to any appointment. In the event a patient won't show up for an appointment, they can easily cancel the appointment on time, helping healthcare facilities reduce losses associated with unused man-hours and other resource.

Over time, MedAwatar’s digital appointment scheduling system will help cut the number of no-shows, optimizing resource utilization and maximize revenues therein.

6. Interoperability
Interoperability, which stands for the ability of different tech systems to communicate and interact with one another, is another unique benefit that MedAwatar will introduce.

By leveraging XDC’s hybrid blockchain, MedAwatar will communicate easily with systems built on different blockchain networks, or numerous solutions within the ever-expanding XDC ecosystem. To add, working with Plugin’s wide array of data sets, MedAwatar will easily communicate with systems that employ unique data to deliver their services in the healthcare space.

With high interoperability, MedAwatar will benefit from high scalability, fast operational speeds and nearly non-existent gas fees. This will help MedAwatar provide an exceptional healthcare platform, helping boost healthcare within India.

Final Thoughts

As the healthcare space continues to evolve, there's a need to adopt solutions that consider new shifts in healthcare as well as leverage new innovations to boost the quality of healthcare. One of the unique ways to develop and integrate innovative healthcare solutions is through game-changing partnerships. An example: the Plugin--Awatarpay partnership.

The collaboration will steer the development of MedAwatar--a healthcare solution that’ll streamline patient scheduling, generating unique user IDs for healthcare users, and more. By leveraging the XDC blockchain network and Plugin’s distributed oracle network, the enterprise solution will avail numerous benefits to India’s healthcare. These benefits relate to compliance, convenience, scalability, improved workflows, reducing no-shows, and high interoperability.

PROOF OF PLI STAKING RESERVE: LET’s BUILD ON FOUNDATIONS OF TRUST

Plugin, Decentralized Oracle — Fri, 13 Jan 2023 07:48:15 +0000

The world is continually and rapidly transitioning to cryptocurrencies. However, as crypto becomes more popular, more players are more likely to be exposed to deteriorating crypto assets. And knowing that some cryptocurrencies come with very few consumer protections, retail investors may have no idea what they’ll own after a certain period or event.

Lack of transparency, caused by opaque regulatory, security, and privacy guidelines, has compounded the problem therein. And going by industry events, there’s a need for crypto projects to adopt more transparent ways of managing their funds.

What’s Plugin’s Proof of PLI Staking reserve?

Plugin, which remains committed to transparency, seeks to reassure community members by availing an easy-to-use interface where Node Operators and Yield Farmers can verify their stake. Hence, Plugin developed the Proof of PLI Staking Reserve.

Proof of PLI Staking Reserve main objective is to increase the community member’s "Trust" and "Transparency". To increase the community’s trust and transparency, the system helps members check whether their PLI stakes are locked in smart contracts and that there’s no entity or individual that has central control over the stake.

To increase trust and transparency, further, it directly brings the total staking balance from the smart contract in real time. The numbers are taken directly from the contract without any mathematical projection. This aspect of this proof of reserve introduces some unique benefits. The first benefit is security and transparency. With each stake published on Plugin’s blockchain, and each record of a completed transaction being available for anyone to review without revealing the owner’s identity, the system ensures that your stake is secure. At the same time, the platform ensures transparency since parties can check records of completed transactions at their convenience. Coupled with the fact that information stored on a blockchain is immutable, Plugin’s proof of PLI staking reserve helps increase trust, transparency, and security.

Another benefit introduced by Plugin’s proof of PLI staking reserve is accessibility. Thanks to the web-based platform, you (the yield farmer or node operator) can access the platform from any location across the globe. You’ll only need an internet connection to verify your stake's status. Ease of access helps reassure community members of the safety of their stake.

Given that there isn't central control over the stake, you (the node operator or yield farmer) interact directly with Plugin; hence, the process of verifying your stake is free. Therefore, the Plugin proof of reserve allows you to check your assets without cost-related limitations. What’s more, free verification of stake encourages you to keep track of PLI-related transactions as recorded on XDC Network’s smart contracts. Ultimately, the transparency and security, made possible by free operations on Plugin’s proof of reserve platform, help build trust.

How can Users check the Liquidity and Solvency of their Stake?

To check the liquidity and solvency of a stake, you only need to visit the Plugin proof of PLI staking reserve platform. Here’s a brief guide for either the node operator staking overview or yield farming overview section.

For the node operators, you need to click on the “verify now” button in the node operator staking overview section. Once on the XinFin Explorer page, you can search for a specific transaction using a transaction hash (Txn Hash). Note: a transaction hash serves as a unique identifier that’s similar to a receipt and that confirms a transaction’s validation and addition to Xinfin’s blockchain.

As well, you can add addresses involved or block numbers to the search bar to view an overview of a certain transaction. On the overview page, you can independently audit your transactions as a node operator. Key metrics you should consider when auditing a transaction include the addresses involved, a transaction’s status, the block number, the transaction value, and the gas price incurred in your transaction.

For Yield Farmers, click on “verify now” button in the yield farming overview section. On the search bar, add your transaction hash, addresses involved, or block number to have an overview of your transaction. With the overview, you can independently check the status of your transaction, the addresses involved, fees incurred, etc.

Kindly note: The token price, reward frequency, minimum deposit, and total tokens staked by node operators and yield farmers are updated in real-time.

Are there conditions to be met before withdrawing one’s stake?

On Plugin, every stake has a one-year lock-in period. This implies that you are required to maintain your stake for a full year in order to be eligible for an unstake or a withdrawal.

Nonetheless, Plugin understands the needs of its community members and remains committed to improving their positions. Therefore, Plugin’s governance committee often accepts requests to unstake assets before the lock-in period elapses. Kindly note, the governance committee only accepts requests that are backed by legitimate reasons. Asking for appropriate reasons prior to unstaking assets is important to avert misuse by users and to guarantee adherence to preset guidelines---that are meant to improve the positions of each user. Sticking with conditions required prior to withdrawing one’s stake guarantees sustainable operations and ensures appropriate returns for the respective parties. In turn, sustainable operations and appropriate returns increase trust.

Bottom-Line

As cryptocurrency becomes more mainstream, there’s a need to build systems that ensure transparency and security, and build trust. Going by recent events in the crypto industry, there’s a need to ensure that users can easily verify the liquidity of their assets and the solvency of their crypto platform.

In this context, Plugin, which is an entity that remains committed to security and transparency, has introduced the Proof of PLI Staking Reserve platform. The platform allows node operators and yields farmers to ascertain their stake at any given time. Thanks to the direct projection of values from the smart contract, the web-based nature of the platform which eases access, and the free nature of verifying transactions, users can check on the status of assets without restrictions. The resulting transparency helps build trust among stakeholders.

How a Plugin Node Reputation is calculated?

Plugin, Decentralized Oracle — Tue, 28 Jun 2022 09:32:12 +0000

The HIGH Reputation of a node is very critical to strengthening our Plugin Oracle Network, hence it is the prime responsibility of every node operator to periodically review their node health by ensuring high time availability.

Plugin Node Reputation is calculated based on the following metrics

24/7 Node Availability
Keeping Plugin Node and External Initiator Running all the time so as to listen to the events
Response time for the oracle service
Data Quality(if node operators act as a data feed provider)
Data Integrity

To start with, we are measuring 24/7 Node availability by periodically pinging the nodes and it will be once a day. So every node will go through this audit on daily basis and the stats will be captured.

Reputation will be calculated based on the number of days a node is up for a month. So monthly reputation along with cumulative reputation will be shown to the node operators.

If you see "0" in your reputation, either your node is newly approved or your node is down and not responding to our audit job.

If your node is newly approved, you can see your reputation from the very next day only. So no action is required from your end.

If your node is running for a long time and you see "0", would suggest you review the server and see if anything is blocking the audit job to review the metrics.

As a node operator, it is very important to keep your server healthy by periodically reviewing it and ensuring high time availability. The Plugin Team, strongly believe that reputation will help every node operator to stay on top of their node service.

Please visit the following link for detailed information.

How to deploy your own Oracle contract and add jobs to your PLI Node

Plugin, Decentralized Oracle — Tue, 14 Jun 2022 07:33:09 +0000

Deployment
Using Oracle contract, you can use your own node to fulfill requests. This guide will show you how to deploy your own Oracle contract and add jobs to your node so that it can provide data to smart contracts.

Requirements
Before you begin this guide, complete the following tasks to make sure you have all of the tools that you need:

Set up XDCPay and obtain Apothem(Testnet) PLI.
Configure an Xinfin client with an active websocket connection.
Run a Plugin Node and connect it to a supported database.
Fund the XDC Wallet address that your Plugin node uses. You can find the address in the node Operator GUI under the Keys tab. The address of the node is the Regular type. You can obtain test ETH from several faucets.

Address Types
Your node works with several different types of addresses. Each address type has a specific function:
Node address: This is the address for your Plugin node wallet. The node requires native blockchain tokens at all times to respond to requests. For this example, the node uses XDC. When you start a Plugin node, it automatically generates this address. You can find this address on the Node Operator GUI under Keys > Account addresses.
Oracle contract address: This is the address for contracts like Operator.sol or Oracle.sol that are deployed to a blockchain. Do not fund these addresses with native blockchain tokens such as XDC. When you make API call requests, the funds pass through this contract to interact with your Plugin node. This will be the address that smart contract developers point to when they choose a node for an API call.
Admin wallet address: This is the address that owns your Operator.sol or Oracle.sol contract addresses. If you're on OCR, this is the wallet address that receives PLI tokens.

Please visit https://docs.goplugin.co/oracle/deployment for detailed further information.

PLUGIN, a true decentralization can be achieved with its Oracle

Plugin, Decentralized Oracle — Thu, 02 Jun 2022 08:48:40 +0000

What is Plugin?
PLUGIN - a Secure, Scalable Decentralized Oracle Platform built on XDC Network Ecosystem, provides cost effective solutions to any smart contract which runs on XDC Network Ecosystem. Plugin enables the smart contract to connect with the real-time world and the data that it receives from the data feed provider is trustable by maintaining a high degree of security. Off-chain computation takes care of receiving feed from multiple providers and aggregates the same.

PLUGIN for Customers
Majority of PLUGIN users relying on smart contracts make use of data feeds. These are reports on the current value of key pieces of data according to authoritative off-chain sources. For example, price feeds are feeds reporting the prices of assets—crypto-currencies, commodities, forex, indexes, equities, etc. — according to exchanges or data-aggregation services. Such feeds will help secure billions of dollars in on-chain value through their use in DeFi systems such as Aave and Synthetix. Other examples of PLUGIN data feeds include weather data for crop insurance, Weather Forecast, Inflation data, Aviation, NFT, among a number of others.

About PLUGIN
PLUGIN is part of XDC Network EcoSystem, and this network is driven through a pool of oracle node operators & data feed providers. With an effective & robust carrot and stick model, the node operators are rewarded with PLI tokens for ensuring 24/7 network availability with high data integrity. Unlike the centralized oracle services where the data reliability is on one data source, PLUGIN being decentralized ensures no single point of failure by aggregating the values from different data sources through oracle nodes with least transaction cost at a highly affordable oracle (PLI) fee.
