Summary: So, when we're diving into the world of healthcare apps using blockchain, the big focus is on a few key things. First off, we want to make sure our records can't be messed with - think of them as super secure and reliable. Then, it's all about knowing exactly where our data comes from. Lastly, we need to ensure that sharing this data complies with all the rules while keeping everything within secure networks. On the flip side, when it comes to developing healthcare apps for Web3, things really kick up a notch. We're talking about cool features like decentralized identities, digital wallets, verifiable credentials, incentive systems, and decentralized storage. It’s all about making healthcare more secure and user-friendly! This creates some exciting opportunities for new patient-centered solutions and collaboration across different networks. However, it also comes with its own set of challenges, like dealing with regulations, figuring out the tech architecture, and getting the overall product design just right.

Blockchain Healthcare App Development vs Web3 Healthcare App Development: What’s Different?

Healthcare decision-makers are increasingly hearing about the importance of exploring blockchain technology. So, here we are in 2026, and it’s becoming pretty clear what the big question is: when should you stick with a classic blockchain app, and when’s the right time to jump into a Web3 app that includes features like wallets, decentralized identity, and verifiable credentials? Let’s break it down. I’ll give you a detailed comparison that goes into the nitty-gritty of engineering, complete with some real-world examples, timelines you should consider for both the US and EU, and a look at those exciting new stack options that are really gaining momentum in production.

Quick definitions you can use with your team

• Building Blockchain Apps for Healthcare.
• What it is: These are apps that tap into the cool capabilities of a distributed ledger to track all sorts of events. Think of things like audit logs, supply chain transfers, or even consent receipts. They collaborate within a known group of participants, sticking to a straightforward governance model, and typically operate in a permissioned environment. One of the biggest perks is that you get a tamper-proof, shared state, which makes it super easy to sort things out when needed.
• Building Healthcare Apps for the Web3 World.
• What it is: So, this takes everything we talked about before and adds some cool extras. We're talking about things like wallets, decentralized identifiers (DIDs), verifiable credentials (VCs), and decentralized storage. Plus, there might be some tokenized incentives or even a DAO-style governance thrown in the mix! With this setup, patients get to keep their own identity and data safe while also making it super easy to verify things across various platforms. What’s really exciting? It’s all about putting users first with identity and trust that you can take with you wherever you go online. If you’re wondering what Web3 is all about--think decentralization, permissionless access, and native payments--you should definitely take a look at Ethereum.org. They’ve got some great info that really breaks down the key features!

Why This Distinction Matters Now

This distinction is really important at the moment since the standards we can actually work with have finally settled down. The DID Core is officially recognized as a W3C Recommendation, and so is the Verifiable Credentials 2. The 0 family officially hit W3C Recommendation status in May 2025! So, when it comes to Web3 healthcare trends, you'll have the chance to use well-established standards instead of piecing together some patchwork cryptography. It's a pretty exciting shift! Take a look at it here: (w3.org).

Regulatory clocks you cannot miss (US and EU)

• ONC HTI-1 and how enforcement discretion plays into it. So, there's been a bunch of updates on health tech certifications lately--like the USCDI v3 and the new SMART App Launch v2--but they've all been postponed for now. Good news! Because of some enforcement discretion, certified health IT developers have until March 1, 2026, to launch those HTI-1-compliant updates for their clients. So, there’s a bit more breathing room for everyone involved! It's a good idea to make sure you design for SMART v2 as the default option right from the start. Oh, and just so you know, certified APIs have to be able to take back an app’s access within an hour if a patient asks them to. It's all about keeping that access in check! (healthit.gov).
• TEFCA and FHIR So, the TEFCA Common Agreement has set the stage for FHIR-based exchanges, specifically with version 2. It's pretty exciting to see how this framework is coming together! You’ve got 0 coming up due in April 2024, and then there's also 2. 1 (set to drop in November 2024). Looks like there are some exciting plans in the works for QHIN-to-QHIN FHIR pilots set to launch in 2025! At the moment, there are eight official QHINs, and it looks like the transaction volume under TEFCA is really starting to pick up. If you’re diving into national exchange workflows, make sure to put TEFCA interoperability at the top of your list. It’s a crucial piece of the puzzle for getting everything running smoothly. (rce.sequoiaproject.org).
• CMS Prior Authorization APIs (CMS‑0057‑F). So here's the deal: by January 1, 2027, payers are going to have to get their act together and launch FHIR-based APIs for Patient/Provider Access, Payer-to-Payer interactions, and Prior Authorization. And just to give everyone a heads up, they'll need to start the operational reporting as early as January 1, 2026. To make things run smoothly, it's a good idea to line up your payer and EHR integrations with your data models and consent scopes. This way, you can stick to the Da Vinci CRD/DTR/PAS IGs. (cms.gov).
• FHIR versioning Hey everyone! Just a quick heads-up that FHIR R5 has officially dropped and people are really starting to use it in tons of the latest implementation guides. Pretty exciting stuff! When you're working on your data layer, try to keep it flexible! You want it to handle both R4 and R4B in production smoothly, but also be ready to bring in R5 where it makes sense. Just think of it like making sure your outfit works for both a casual day out and a fancy event - versatility is key! Hey, just a quick reminder to make sure you set aside some time to plan for Bulk Data (Flat FHIR) 2! You won't want to overlook it! It looks like you're working with backend services and setting up some authorization, right? Let me know if you need any tips or if there's something specific you'd like to dive into! (hl7.org).
• DSCSA (U.S. Pharma Supply Chain). Hey there! Just wanted to share some news from the FDA. They've actually extended the enforcement exemptions, which is great for a lot of folks. So, if you're a manufacturer or repackager, you've got some extra time--until May 27, 2025. Wholesalers are in the clear until August 27, 2025, and large dispensers can breathe easy until November 27, 2025. Definitely helps to lighten the load a bit! If you've got small dispensers, you've got a little more breathing room! The deadline for those is set for November 27, 2026. If you’re diving into drug traceability, it’s super important to ensure your system can manage package-level tracking and verification that works well across different platforms. Make sure it meets all the necessary timelines too! (fda.gov).
• EU: European Health Data Space (EHDS) and eIDAS 2.0

So, let's talk about the European Union's move towards improving health data management through something called the European Health Data Space (EHDS). This initiative is all about making health data more accessible and usable across member states. It’s designed to ensure that individuals can have more control over their own health information while also supporting research and innovation in healthcare.

And then there's eIDAS 2.0, which is a part of this whole effort too. eIDAS stands for electronic IDentification, Authentication and trust Services. It’s all about making online transactions safer and easier across Europe. With this updated version, the EU aims to streamline digital identifications and ensure that people’s identities are secure when accessing different services, including health-related ones.

Basically, both of these initiatives aim to create a more connected and efficient healthcare system, making it easier for people to access the care they need while keeping their data safe and sound. Pretty cool, right? 0**. So, the EHDS Regulation (EU) 2025/327 made its debut on March 5, 2025. It’s going to roll out in phases beginning that same year, but just a heads-up: some of the rules about using data down the line won’t come into play until four years after that. If you’ve got some solutions ready for the EU, just keep in mind that they need to fit with the interoperability standards at the EU level and how secondary-use access is managed. (health.ec.europa.eu). So, let’s chat about eIDAS 2. With the kick-off of 2024, things are really starting to take shape with the European Digital Identity Wallets (EUDI) and the whole digital initiative. Exciting times ahead! Member States are planning to launch at least one certified wallet by the end of 2026. Hey there! If you're working with patients in the EU, it’s really important to get ready for wallet-based identity management and qualified e-signatures. Just think of it as part of your plan to keep things smooth and secure for everyone involved! (consilium.europa.eu).

Architectural distinction in practice

1) Identity and access

• Classic blockchain app Imagine it like having a solid enterprise identity and access management system (IAM) paired with API keys or OAuth2. It’s all about linking identities to your organization’s directories, while the ledger keeps track of those important system-of-record events.
• Web3 healthcare app This setup makes use of DIDs and VCs to handle the identities and privileges of both patients and providers. It's all about wallet-focused processes, letting you choose what information to share and even take it back if you need to. Plus, it uses privacy-friendly status lists to keep your stuff secure. The DID Core is all set with a standard, and so are the Verifiable Credentials (VCs). You have some choices when it comes to JOSE/COSE and Data Integrity. Oh, and don’t forget about the Bitstring Status List 1! 0 makes revocation scalable. Take a look at this: (w3.org).

What this unlocks: You’ve got these handy card-style credentials for vaccines, clinical jobs, or proof of coverage. You can easily show them off wherever you need, and guess what? No need for any direct connections to an EHR system! Take a look at how we've shifted from using SMART Health Cards to now incorporating FHIR-modeled verifiable clinical info. It's a pretty exciting change! (hl7.org).

Implementation Tip:

Imagine a patient's wallet as a sort of "consent oracle." It's like a little treasure chest that holds all the keys to understanding their preferences and agreements. "Use EIP-712 typed data to generate consents that people can actually read and understand, while also ensuring they’re securely cryptographically signed and connected to FHIR Consent resources." To keep things simple, just store hashes or commitments on-chain, and leave the official consent object off-chain. Take a look at it here: eips.ethereum.org.

Example EIP‑712 Typed Data for a Consent Attestation (Hash Stored On-Chain)

Alright, let’s talk about consent attestation! Here’s a simple way to put together the EIP‑712 typed data. Here's a quick and easy example to kick things off for you.

{
  "types": {
    "EIP712Domain": [
      { "name": "name", "type": "string" },
      { "name": "version", "type": "string" },
      { "name": "chainId", "type": "uint256" },
      { "name": "verifyingContract", "type": "address" }
    ],
    "Consent": [
      { "name": "attester", "type": "address" },
      { "name": "beneficiary", "type": "address" },
      { "name": "dataHash", "type": "bytes32" },
      { "name": "timestamp", "type": "uint256" }
    ]
  },
  "primaryType": "Consent",
  "domain": {
    "name": "ConsentAttestation",
    "version": "1",
    "chainId": 1,
    "verifyingContract": "0xYourContractAddressHere"
  },
  "message": {
    "attester": "0xAttesterAddressHere",
    "beneficiary": "0xBeneficiaryAddressHere",
    "dataHash": "0xYourDataHashHere",
    "timestamp": 1634515200
  }
}

Go ahead and throw in your own addresses and values wherever it makes sense! This setup is designed to make sure that the consent info is organized the right way and can be easily checked on-chain.

{
  "types": {
    "EIP712Domain": [
      {"name":"name","type":"string"},
      {"name":"version","type":"string"},
      {"name":"chainId","type":"uint256"},
      {"name":"verifyingContract","type":"address"}
    ],
    "Consent": [
      {"name":"consentId","type":"bytes32"},
      {"name":"patientDid","type":"string"},
      {"name":"fhirConsentUri","type":"string"},
      {"name":"purposeOfUse","type":"string"},
      {"name":"expiresAt","type":"uint64"}
    ]
  },
  "primaryType": "Consent",
  "domain": {
    "name": "7Block Labs Consent",
    "version": "1",
    "chainId": 8453,
    "verifyingContract": "0x..."
  },
  "message": {
    "consentId": "0xabc...def",
    "patientDid": "did:web:wallet.example/patient123",
    "fhirConsentUri": "https://ehr.example/Consent/789",
    "purposeOfUse": "treatment",
    "expiresAt": 1798752000
  }
}

Standards Alignment

To back up the signed message, go ahead and use a FHIR Consent resource (either R4 or R5). Don’t forget to apply the scopes using SMART v2 along with UMA 2. There's a policy in place right at the gateway. UMA lets users manage authorization on their own terms, and it works seamlessly across various resource servers. Take a look at this link: (hl7.org). You might find it interesting!

2) Data placement and privacy

• Classic Blockchain App
• On-chain: We're talking about event IDs, the ins and outs of supply chain transfers, and those important document hashes. When we say "off-chain," we're diving into the world of Protected Health Information (PHI) found in Electronic Health Records (EHRs) and data lakes. On top of that, we have de-identified aggregate data that's perfect for analytics. And of course, everything's secured with standard access controls to keep it all safe and sound.
• Web3 Healthcare App We rely on off-chain encrypted data vaults or decentralized storage options, such as IPFS or Filecoin. These come with content that you can address using CID, and thanks to on-chain commitments and access policies, everything stays super secure. Just a quick heads up: it's really important not to store any PHI in plain text on public blockchains. Trust me, you don't want to take that risk! IPFS CIDs are pretty awesome! They’re these unique identifiers that come straight from the content itself. What’s really neat is that they can verify the integrity of the data without actually revealing where it’s stored. How cool is that? Plus, with Filecoin/IPNI, it’s super easy to track down providers for a specific CID and grab your data using Graphsync, Bitswap, or HTTP. Take a look at this: docs.ipfs.tech. You'll find some really interesting info there!

Compliance Note:

So, when we're talking about HIPAA de-identification, there are basically two key approaches you can take: safe harbor and expert determination. Don't forget to encrypt your re-identification keys and keep them separate! It's really important for security. Hey there! So, if you're working with EU public chains, just a quick heads-up: remember the EDPB guidance. It’s best to avoid putting any personal data on the chain. Better safe than sorry, right? Instead, consider going for off-chain deletion or getting rid of the keys altogether. That way, the data won’t be linked to anything. For more info, just click here. You’ll find all the details you need!

3) Interoperability with US healthcare rails

• Classic blockchain app Hey there! If you're looking to link up with TEFCA, you'll want to connect through your QHIN or participant. From there, you can start exchanging C-CDA and FHIR payloads according to the CA v2 guidelines. Happy connecting! x policy. Take a look at this: rce.sequoiaproject.org. You might find it pretty interesting!
• Web3 healthcare app
• Make sure to include wallet-based identity and verifiable credentials (VC) proofs in your TEFCA and FHIR workflows. Get excited for the upcoming QHIN-to-QHIN FHIR API pilots! These initiatives are going to set the stage for smooth, API-driven exchanges throughout the network. Hey, don't forget to link those VC claims to the USCDI data classes when you’re sharing them! If you want more details, you can check it out here: (healthit.gov).

4) Decision support and tokenized incentives

• Classic blockchain app Consider it a great way to stay organized when it comes to keeping tabs on decision support materials. The HTI‑1 "Decision Support Interventions" really drives home the importance of being transparent and sticking to real-world testing standards. This definitely affects how you present your metadata, whether you're using blockchain or not. Check it out here.
• Web3 healthcare app
• This creates a cool opportunity to issue VC-backed attestations for stuff like tracking where models come from or getting patients more involved in the process. There’s some really cool research happening around ZK proofs right now! These proofs allow you to show that a model or dataset meets specific requirements without revealing any sensitive information. It’s such a useful tool for AI collaboration between different institutions! Check out the details over here. You'll find some pretty interesting stuff!

A) National drug traceability that clears DSCSA deadlines

So, we’re diving into a permissioned blockchain app that’s built specifically for manufacturers, wholesalers, and dispensers. Essentially, it helps them keep tabs on package-level events and make sure product identifiers are legit. So, these permissioned chains, especially the ones that use Hyperledger, really align well with the DSCSA's idea of “known trading partners.” They really help minimize the exposure of PHI while staying in line with FDA guidelines and their gradual enforcement strategy. If you want to dive deeper into this topic, just head over to fda.gov. There's plenty of information waiting for you!

We're going to store serialized identifiers, EPCIS events, and all that compliance metadata directly on the blockchain. So, when it comes to labels and documents, we’re actually going to keep those stored off the chain. But don’t worry, we’ll still have their hashes securely saved on the chain. This way, we can ensure everything is safe and sound! On top of that, we’re going to put in place some backup plans for any issues that might pop up with verification and returns that can be sold.

When you're looking at Web3 in this situation, try to think of it as a method for storing big files using CIDs, instead of focusing on tokenizing drugs. The real benefit here is all about traceability and interoperability--it's not really just about managing tokens. If you want to dive deeper and get more insights, check out docs.ipfs.tech. It's packed with useful information that you might find helpful!

B) Patient‑held consent that travels across EHRs and payers

• Create it as a Web3 app:
• Alright, let’s get started! First up, we’ll create a patient DID using did:web/did:key and set up a wallet.
• Credential: Imagine a scenario where a VC says, “Patient X agrees to share resources Y for the purpose of Z until T.” Oh, and by the way, there's a Bitstring Status List entry in case we decide to revoke it down the line.
• Reference: Check out this super useful link to a FHIR Consent resource if you need all the legal nitty-gritty for any of your systems. On top of that, patients will need to sign an EIP-712 typed message to give their clear, human-readable consent. (w3.org).
• Enforcement: On the API front, we're rolling with SMART on FHIR v2. If a patient asks for token revocation, it all goes down within an hour. Plus, UMA 2. With 0 profiles, we can keep user-controlled access organized across various data providers. (mwe.com).

So basically, what this means is that consent is now more flexible. It’s not just stuck to one provider's portal anymore. Auditors will have the ability to check cryptographic traces without having to worry about any personal health information (PHI) being stored on the blockchain.

C) Wallet‑based clinician credentials for faster onboarding

How about building a Web3 app that issues verifiable credentials (VCs) for clinical roles? It could also connect to NPI numbers and help manage various privileges. This way, we can streamline the whole process and ensure everything’s secure and trustworthy! When a verifier, like a hospital or a telehealth service, wants to check someone's credentials, they just search for the issuer’s decentralized identifier (DID) along with the credential status. It's pretty straightforward! Say goodbye to the hassle of emailing PDF licenses back and forth! With FHIR-modeled attestations, you can easily add links to the original sources, making everything more authentic and trustworthy. (w3.org).

D) Prior authorization automation

• Create a hybrid system that combines FHIR APIs just like it’s been laid out in CMS-0057-F. Don’t forget to incorporate the Da Vinci CRD, DTR, and PAS as well! You might want to think about reaching out to VCs to check on coverage or see if there are any prior approvals with downstream providers. It could save you some hassle down the line! This way, you won’t have to keep going back to the payer APIs all the time, but you’ll still have a reliable record of any updates. Just a heads up--when you’re planning for the 2026 reporting, make sure you’ve got your go-live timed out perfectly with the API standards by January 2027. It’s important to stay on top of those deadlines! For more info, be sure to swing by the CMS website. They'll have all the details you need!

Data‑security playbook that works in both models

• Zero Trust right from the start. Imagine wallets, consent services, and FHIR APIs as different areas where trust is built. Each one has its own space and vibe. Make sure to always authorize, segment things correctly, and don’t forget to keep those logs! Hey, if you’re interested in Zero Trust Architecture (ZTA), you should definitely take a look at NIST SP 800-207. It's packed with some solid patterns that could really help you out! (csrc.nist.gov).
• PHI should never be on public chains. Just a heads-up: it's best to focus on off-chain encryption, envelope keys, and on-chain commitments. Keep it simple and stick with those! In the EU, the EDPB is all about promoting privacy from the get-go. They really emphasize the importance of building privacy into everything and recommend steering clear of keeping personal data on the blockchain. Alright, so here's the game plan: we need to focus on key destruction and making sure we erase any off-chain data. This will help us achieve a strong level of "unlinkability." ” (edpb.europa.eu).
• De‑identification rigor
• If you’re sharing data for research, feel free to use either the HIPAA Expert Determination method or the Safe Harbor approach. Hey, just a quick reminder to make sure you keep track of your risk analysis and any changes you make as you go. It's super important to document everything! (hhs.gov).
• Decentralized storage hygiene So, tools like IPFS and Filecoin are pretty awesome! They use this thing called content-addressing, which means they keep everything super secure with unique identifiers called CIDs. That way, you can trust that the content hasn’t been changed or messed with. Make sure to keep that PHI nice and secure by encrypting it and controlling who has access to it. It's super important! Also, make sure you've got clear guidelines for pinning and retrieving data. And don’t forget to check out provider availability through IPNI--it's super helpful! (docs.ipfs.tech).
• Consent lifecycle When you're working on modeling consent in FHIR, make sure to connect those human-readable messages that are signed with EIP‑712 to the Consent resource. Just make sure you've got a simple way to withdraw consent whenever you need to, and that you're clear about how you're using that info, in line with SMART v2/HTI‑1 guidelines. (hl7.org).

Chain and stack choices in 2026

• When should you go for a permissioned blockchain? If you’re looking to set up a system for tracking or auditing that involves multiple parties and you’re dealing with known players, then a permissioned blockchain is the way to go. This is especially true for situations like the DSCSA, tracking the origin of medical devices, or keeping tabs on clinical trial supplies. So, when it comes to those kinds of scenarios, a permissioned blockchain can really make things easier! What you really want here is to make sure performance is reliable, your private data stays secure, and there's solid governance set up.
• So, when should you think about adding Web3 layers? If you need to verify patient or provider credentials, check across different networks, or manage data in a more decentralized way, that’s definitely a good time to think about adding some Web3 technology. This might mean sharing patient-centered records between TEFCA participants, making coverage or role confirmations easy to carry around, or even giving users the option to bring their own identity when they're signing up.
• DID/VC stack
  If you're diving into DID methods, I recommend starting with did:web. It’s super straightforward when it comes to issuing and managing things. Once you’ve got that down, you can think about how you want to upgrade from there! Just double-check that against DID 1, okay?

0. So, when it comes to your crypto or tools, you can go with either VC Data Integrity or JOSE/COSE, in line with VC 2. It really depends on what you're working with! 0. For more info, just swing by w3.org. You'll find all the details you need!

• API/interoperability
  Just a heads up, make sure you have SMART on FHIR v2 ready to go by the HTI-1 deadlines. It's definitely something you don't want to overlook! Hey there! Just a heads up, it’s time to gear up for those Bulk Data exports. Also, let’s ensure that R4 and R5 can work together smoothly as TEFCA FHIR begins to roll out via the QHINs. Exciting times ahead! If you're looking for more details, check out mwe.com. They've got the scoop!
• Authorization
• With UMA 2. With your skills, you can totally bring user-managed, cross-resource consent to life! Simply link your policy to the VC claims and FHIR Consent to ensure everything stays in harmony. If you're looking for more info, just check out docs.kantarainitiative.org. That’s where all the details are hanging out!

Risks and how to derisk them

• "Right to erasure" vs. immutability. So, EU regulators like the EDPB and CNIL are on the lookout for designs that avoid putting personal data directly on the blockchain. They’re really pushing for solutions that either keep that info off the chain altogether or make it super tough to trace back to individuals--like deleting data off-chain or destroying encryption keys. Rather than keeping personally identifiable information (PII) directly on the blockchain, it’s better to design a system that prioritizes revocation or status management. This way, you can still maintain privacy and security without putting sensitive info at risk. If you're interested in learning more about this, feel free to check it out here!
• Reproductive Health Privacy in the US. Hey there! Just a heads up--the new 2024 HIPAA reproductive privacy rule has undergone a few changes. However, some sections will still need to be compliant by February 16, 2026. So, make sure to keep that date in mind! With the legal landscape constantly changing, it’s a good idea to keep your policies flexible and really focus on consent scopes and audit trails. If you want all the details, just click here. You'll get the complete picture!
• Tokenization and incentives In clinical environments, it’s a good idea to start with non-transferable attestations (VCs) before jumping into tokenization. It’s like laying a solid foundation before building the rest of the house! If you decide to go the token route, just a heads up: it’s super important to keep it separate from any PHI flows. And don’t forget to bring in your legal team early on--they can really help steer things in the right direction!

Build roadmap we recommend (12-18 months)

1) Foundations

• Get your "rails" sorted: It’s super important to figure out your TEFCA integration strategy first. Think about how you’ll connect with participants and QHINs. Also, don’t forget to outline your game plan for rolling out SMART v2, and make sure you’ve got a solid strategy in place for FHIR R4/R5. Plus, be clear about what you want to cover with Bulk Data. Check it out here.
• Identity: We're focusing on issuing Digital IDs for both patients and healthcare providers. Oh, and definitely keep the wallet user experience for consent nice and easy for folks to navigate. And hey, don’t overlook that status list service either! Want to dive deeper? Check out all the info here. It's got everything you need!
• Authorization: Set up UMA-enabled consent enforcement and make sure we can revoke access on an hourly basis. Make sure everything lines up with HTI-1 and HIPAA. It's super important! Get the scoop here.

First Use Cases

• We’ve got this cool system for patient-held consent that manages who can access the FHIR API, and it works across two different EHRs and one insurance company. We've set a clear goal for revocation that aims to be completed in under 60 minutes from beginning to end. This is actually even better than what the HTI-1 revocation requirements ask for! (dynamichealthit.com).
• Clinician credential VC acceptance is now part of our onboarding process, and it's a total game changer! We’ve really streamlined things and reduced the time it takes to get those privileges. No more annoying manual verification loops slowing us down! (w3.org).

3) Scale and Harden

• Look into using decentralized storage for non-PHI files. Just make sure they're hash-verified for that extra layer of security! Make sure to encrypt all your PHI vaults, and definitely avoid keeping any plaintext data on-chain. It's just not a good idea! Hey, just a quick reminder to make sure you’re documenting your DPIAs for those EU pilots! It’s super important. You can check out more info here. Happy documenting!

For our pharmaceutical clients, it's super important that we move the DSCSA event streaming to a permissioned ledger. Just a friendly reminder to double-check that everything is in line before those exemption deadlines sneak up on us! (fda.gov).

Bottom line

If your goal is to achieve multi-party auditability with a set group of known players, a traditional blockchain app is the way to go. Imagine getting into the nitty-gritty of supply chain management, tracking device histories, and making sure those unchangeable logs stay in place. And all of this while maintaining a centralized identity and having smooth API access. It’s like juggling a bunch of important tasks to keep everything running seamlessly! On the other hand, if you're looking to handle identities and credentials for patients and providers across different organizations and even countries, then a Web3 healthcare app is definitely the way to go. This setup makes it super easy to get consent on the go and keeps everything stored in a decentralized way. Plus, it’s built to work smoothly with TEFCA, SMART on FHIR v2, and those CMS prior authorization APIs. So it’s really user-friendly and fits right into the current healthcare tech landscape.
