Executive summary

We've got to keep in mind that the timelines for eBL, DSCSA, EUDR, FSMA, and the EU Battery Passport are really influencing our decisions about the architecture.
If you want to really see a good return on your investment, it’s a smart move to pay attention to interoperability, especially with standards like GS1 EPCIS 2. Hey there! Just so you know, I'm up to speed with data until October 2023. By the way, we're diving into W3C Verifiable Credentials 2. Exciting stuff, right? So, we've got SD-JWT, which follows RFC 9901, and then there's the DCSA eBL. The best programs out there are the ones that combine off-chain EPCIS event stores with on-chain integrity proofs. It's like the perfect blend of two worlds! They use verifiable credentials for claims about both the participants and the products, plus they tap into zero-knowledge selective disclosure. This way, they can nail those audits without giving away any sensitive information about their suppliers. Pretty smart, right? (gs1.org).

Why now: deadlines, standards, and paperless trade momentum

• FDA FSMA 204: So, here's the scoop! The FDA initially had us all set to comply by January 20, 2026. But guess what? They've now decided to push that date back. They won’t be enforcing it until July 20, 2028, thanks to a nudge from Congress. As you get started on your long-term data projects, don’t forget to tweak your expectations for enforcement. It’s important to keep that in mind! (fda.gov).
• DSCSA: So, here's the scoop: once we get through the stabilization period that's happening in 2023-2024, the FDA is going to start rolling out some staged enforcement exemptions. Here’s how the timeline looks: manufacturers and repackagers have until May 27, 2025, to get in line, wholesalers have a bit longer--August 27, 2025--and dispensers with 26 or more full-time employees need to comply by November 27, 2025. As for the smaller dispensers, they’ve got until November 27, 2026. Mark those dates on your calendar! It's time to kick off your plans for EPCIS 2! Let's get things rolling and figure out how we're going to tackle this. Hey, just wanted to let you know that the exchange process and ATP credentialing is happening right now. (fda.gov). So, here’s the scoop on the EUDR: the EU’s deforestation regulation isn’t going to kick in just yet. Both the Council and Parliament have given the green light for a one-year delay. For those big operators, they now have until December 30, 2025, to get their act together. As for the micro and small operators, they’ve got a bit more breathing room until June 30, 2026. Back in December 2025, the Council made a decision to push back the application deadline for everyone until December 30, 2026. And for the smaller players--like micro and small businesses--they threw in an extra six months to help them out. Now's a great moment to kick off some geolocation-supported traceability. This way, you won’t have to go back and fix things later on. (consilium.europa.eu).
• UK ETDA: As of September 20, 2023, the UK officially recognizes electronic trade documents, including things like electronic Bills of Lading (eBL), as being just as legally valid as their paper counterparts. How cool is that? This is a huge move toward lowering the legal risks tied to digital bills. (legislation.gov.uk).
• DCSA eBL: Ocean carriers are really stepping up their game, aiming to get to 100% electronic Bills of Lading (eBL) by 2030. They're also targeting 50% in just the next five years! It’s a big move towards modernization in the industry. Back in May 2025, they showed off some pretty cool interoperable eBL transactions. And just to give you some context, by January 2025, about 5% of the market had jumped on board. 7%. Sticking with standards-aligned stacks is definitely the way to go if you want to play it safe. (dcsa.org).
• Battery passports: So, the EU has this new rule, Regulation (EU) 2023/1542, that’s going to kick in on February 18, 2027. It’s all about introducing digital battery passports. They've decided to hit the pause button on the due diligence requirements until August 18, 2027. This means we'll need to step up our game when it comes to tracking both electric vehicles and industrial batteries. (eur-lex.europa.eu).

Case A -- Container shipping: eBL + cargo release in production

What Changed from "Nice Pilot" to Scaled Value?

Looking back at the beginning of our project, the phrase "nice pilot" really sums up what we were trying to achieve during those early days. But as we've grown and changed, we've started to zero in on outcomes that are more structured and can be measured more easily. Let me give you a quick overview of what’s new:

Key Changes

1. Objective Measurement
   During the pilot phase, success was mainly determined by instincts and personal opinions. These days, we're really leaning into data to get a clearer, more objective picture of everything.
2. Expanded Scope
   What began as just a little experiment has really taken off! We're now exploring how our pilot can play a role in bigger plans and seeing how it can fit into a larger picture.
3. Feedback Incorporation
   The early feedback we got was mostly positive, but it was pretty laid-back and casual. These days, we're really focused on getting structured feedback so we can keep improving and evolving.
4. Resource Allocation
   The "nice pilot" phase didn't need a lot of resources to get going. We're really putting our efforts into finding tools and tech that can help us keep a better eye on our progress and results.
5. Stakeholder Engagement
   At first, just a few team members were part of the mix. Using the scaled value approach means we really need to connect with a bunch of different stakeholders. It’s super important to make sure everyone’s voice gets heard and taken into account.

Conclusion

Making the shift from a “nice pilot” to a scaled value model really means adopting a more structured way of doing things. It’s all about being more intentional and focused in your approach. It's not just about feeling proud of what we've accomplished; it's also about being able to show the difference we're making and always looking for ways to get better. Let's keep pushing forward!.

• Interoperability and Law: Thanks to DCSA standards and some laws that match up with MLETR--like the UK's ETDA--we’re seeing some serious progress in breaking down the barriers that used to make it tricky to work with electronic Bills of Lading (eBL). Take a look at this: (dcsa.org).
• Network Design: GSBN is proving that a neutral governance setup, along with focused applications like Cargo Release and eBL bridging, really outperforms those big, bulky systems. It’s amazing how streamlined and efficient things can be with the right approach! Great news! Cargo Release is fully operational at 24 ports now and managing more than 1. Can you believe it? We’ve hit 5 million shipments, and the time it takes to get “document-ready for release” has gone from days to just a few hours! If you're curious to learn more about this, check it out at (gsbn.trade).
• Carbon and Cost: A recent study by GSBN found that making the switch to electronic Bill of Lading (eBL) can help save around 28 kg of CO2e for every document. That's pretty impressive, right? We're looking at digitizing about 15 things. If we get rid of 8 million paper bills, we could really make a difference by cutting down about 440,820 tons of CO2e. That’s a huge deal, especially when we're talking about Scope 3 emissions! If you're curious to learn more about this, check it out here: (container-mag.com).
• Interop Milestone: Back in May 2025, the DCSA nailed it by completing a standards-based interoperable eBL transaction that connected multiple providers. How cool is that? This is exactly the kind of template you want to include in your RFP. Learn more at (dcsa.org).
• Lessons Learned: The TradeLens shutdown in 2022 really drives home the point that the industry needs to stay neutral and focus on building sustainable business models. It's a good reminder to avoid relying on just one sponsor for governance. Hey, if you're curious, you can find all the details right here: maersk.com. It's worth a look!

How to Implement in 90 Days:

You know how getting stuff done can feel like trying to solve a massive puzzle? It can be a bit overwhelming at times! But here's the good news: if you put together a solid plan, you can crush any project in just 90 days. Pretty cool, right? Alright, I've got a handy step-by-step guide for you to follow. Let's dive in!

Step 1: Define Your Goal

Alright, let’s dive into this! What do you really want to accomplish? It's super important to make sure your goal is clear and something you can actually measure. Go ahead and take some time to write it down.

So, what does success actually look like? What makes this goal really matter to you?

Step 2: Break It Down

Now that you’ve got your goal clear in your mind, it’s time to chop it up into smaller, bite-sized tasks that are easier to tackle. That really takes the pressure off!

Alright, here’s an easy way to tackle it:

• Go ahead and jot down all the tasks you need to wrap up.
• Try grouping similar tasks together. It makes life a lot easier!

Example Breakdown:

• Research Phase
  • Read articles
  • Watch tutorials
• Planning Phase
  • Create a draft
  • Gather resources
• Execution Phase
  • Implement the plan

Step 3: Create a Timeline

Alright, now that you’ve got your tasks lined up, let’s figure out a timeline. Take a moment to jot down each task on your calendar for the next 90 days. It's a great way to keep everything organized and stay on track!

Why not give tools like Trello or Asana a shot to help you stay organized? They can really make managing tasks a breeze!

• Keep it real about how much time each task will actually take.

Step 4: Stay Flexible

Hey, just a little reminder: life can be unpredictable sometimes. Hey, if things don’t work out the way you hoped, don’t sweat it! Just tweak your timeline a bit and keep pushing ahead. You got this!

• It's smart to have a backup plan in place. You never know when things might not go as planned!
• Stay flexible and be ready to switch things up if you need to.

Step 5: Review and Reflect

Take some time at the end of each week to look back at what you’ve accomplished. It’s a great way to see how far you’ve come! So, what's going well? And what’s not really hitting the mark? Figuring this out can really help you stay on course and tweak things as needed.

Questions to Consider:

• So, did I manage to get all my tasks done this week?
• What can I improve on for next week?

Step 6: Celebrate Small Wins

Hey, don't skip this part! Seriously, make sure you take a moment to celebrate your wins, even if they seem tiny. You deserve it! Go ahead, treat yourself to something nice, kick back for a bit, or show your friends what you’ve accomplished!

Final Notes

Just keep in mind that it's really about making progress, not about being perfect. By the time those 90 days wrap up, you won't just have put your plan into action--you’ll have picked up a whole lot of new insights too! Now, go get started!.

If you're on the hunt for a little extra inspiration or some handy resources, why not take a look at this great article? Or check out this awesome tool that could really help you out! You've got this!.

• Phase 0 (2 weeks): To kick things off, we’re jumping into a legal gap analysis to check out how we measure up against MLETR/ETDA in our trade lanes. We'll also take some time to figure out who our counterparties are when it comes to DCSA eBL capabilities. Check it out here.

Alright, here’s the plan for Phase 1, which is gonna last about 6 weeks. First up, we’re going to set up a gateway. This thing will be capable of a few important tasks: it’ll be able to issue and accept DCSA eBLs, anchor document hashes on a public blockchain, and also connect with those port cargo release APIs at one of the import terminals--kind of like what GSBN does. Sounds pretty exciting, right? If you want to dive deeper into the details, you can check it out here.

• Phase 2 (4 weeks): So, here’s the plan: we’re going to step it up and bring two more carriers into the mix! During this stage, we'll be keeping an eye on cycle time, how often discrepancies pop up, and how well we're doing at dodging demurrage fees. And hey, we’ll also take a look at just how much carbon we're saving by ditching paper! If you’re interested in diving deeper into this topic, feel free to check it out here. It’s got some great information!

KPI Ranges We See:

• Traffic: You’re looking at somewhere between 1,000 to 10,000 visitors.
• Engagement Rate: It usually falls between 2% and 15%.
• Conversion Rate: Anywhere from 1% to 5%.
• Customer Retention: Somewhere between 60% and 90%.

These ranges really give you a solid way to gauge how well things are going in various areas. No matter if you're a newbie or you've been doing this for a while, paying attention to these metrics can seriously help guide your strategy in the best way possible. It’s all about staying on top of things!

• Document cycle time: We're slashing that from a lengthy 3-7 days down to just a few hours! And get this--time spent handling exceptions usually goes down by over 50%. How great is that?
• Discrepancy rate: Things are looking up here! We’re seeing improvement thanks to embracing canonical schemas (DCSA) and establishing a shared identity.

Case B -- Pharma: DSCSA, EPCIS 2.0, and confidential compliance

What’s Required:

• A good attitude: Honestly, having a positive mindset can really change the game. It’s amazing how much of an impact it can have!
• Basic knowledge: You really just need to know the basics of what we’re doing--no pressure to be a pro from the start.
• Team player spirit: It’s all about teamwork! Let’s join forces and support one another. Together, we can achieve so much more!
• Eager to learn: Stay open to learning new skills and rolling with the punches when change comes knocking.
• Good communication: It's super important to keep everyone updated. That way, we all know what's going on and can stay on the same page.
• Time management: With deadlines looming, staying organized is key. We really need to keep our ducks in a row!

Get yourself all set to jump in by keeping these must-haves in mind!

So, we’re diving into the interoperable exchange of serialized data, or EPCIS for short. This also includes some cool stuff like package-level tracking, ATP credentialing, and verification. The rollout for this will happen in stages, and it's set to be fully enforced by 2026 for specific types of partners. Exciting times ahead! If you want to dive deeper into this topic, you can find more info here. It’s worth checking out! The FDA just dropped their final guidance on what the standards are for interoperable exchange. On top of that, industry blueprints, also known as PDG, are playing a big role in how ATP credentials are being shaped with W3C DIDs and VCs. If you want to dive deeper into the topic, check it out here. There's a ton of useful info waiting for you!

Design pattern we deploy:

Let me show you the design pattern we're working with.

1. Singleton Pattern

This is really about ensuring that there's just one instance of a class. It's just what you need when you want to manage who can access shared resources.

Key Features:

• One instance: No matter what happens, you can always count on having just one instance of that class.
• Global access: You can reach that instance from anywhere in your app.

public class Singleton {
    private static Singleton instance;

    private Singleton() {}

    public static Singleton getInstance() {
        if (instance == null) {
            instance = new Singleton();
        }
        return instance;
    }
}

2. Observer Pattern

This is perfect for those times when you want to be updated on any changes happening to another object.

Key Features:

• Loosely connected: The main idea and those watching can totally exist on their own.
• Dynamic subscription: Users can easily subscribe or unsubscribe whenever they're running the program.

public interface Observer {
    void update();
}

public class Subject {
    private List<Observer> observers = new ArrayList<>();

    public void addObserver(Observer observer) {
        observers.add(observer);
    }

    public void notifyObservers() {
        for (Observer observer : observers) {
            observer.update();
        }
    }
}

3. Factory Method

If you find yourself whipping up a bunch of similar objects, the Factory Method could be exactly what you're looking for! It helps you set up a way to create an object, but gives the subclasses the freedom to choose which class they want to actually create.

Key Features:

• Separates object creation: You don't have to lock yourself into a specific class for the object you want to create.
• Flexibility: You can easily add or switch up the types of products in your app whenever you need to.

public abstract class Product {
    abstract void use();
}

public class ConcreteProductA extends Product {
    void use() {
        System.out.println("Using product A");
    }
}

public class Creator {
    public Product factoryMethod(String type) {
        if (type.equals("A")) {
            return new ConcreteProductA();
        }
        return null;
    }
}

Conclusion

Using these design patterns can really help us simplify our development workflow and build applications that are way easier to maintain and scale. Each of them comes with its own set of cool benefits and specific situations where they're really handy. So, it’s definitely smart to have a nice variety of tools at your disposal!

• Event Layer: So, we’re all set with EPCIS 2. We’ve got everything set up for handling sensor data, tracking certifications, and working with JSON-LD. So, this info stays off the main chain to keep everything running smoothly and to make sure we're following GDPR rules. (gs1.org).
• Integrity Layer: So, every hour, we create Merkle roots from EPCIS events and link them to a public chain. It's a pretty cool way to keep everything secure and transparent! This way, we get to have tamper-evidence while keeping our data safe from leaks.
• Identity and Credentials:
  We're using W3C DIDs to manage our organization and system identities. You can check out the ATP status, as well as the wholesaler and dispenser licenses, along with the DSCSA role claims--they’re all listed as Verifiable Credentials. 0;. When it comes to presentations, we typically use SD-JWT (that's RFC 9901 for the techies out there) or BBS+ selective disclosure. These methods help us check if someone is an “authorized wholesaler” without revealing their identity graph. It's a pretty neat way to keep things secure and private! (w3.org).
• ZK Where It Matters: The MediLedger's FDA pilot really highlighted how ZK technology can keep transactions private, and guess what? It worked smoothly, even at a strong industry throughput! It's your trusty way to verify who owns what without spilling the beans on your trading history. (tabletscapsules.com).

Deployment Realities:

Launching your app or system can definitely be a bit of a challenge. Alright, let’s dive into some important points to remember:

Planning Your Deployment

• Define Your Goals: Before you jump in, take a moment to think about what you really want to accomplish with your deployment.
• Pick the Perfect Setup: Figure out where you want your app to hang out--will it be on-site, all up in the cloud, or maybe a mix of both? Every option comes with its own set of advantages and disadvantages.

The Deployment Process

1. Get Your Code Ready: Double-check that your code is all set for deployment! This just means putting it through some solid testing and sorting out any glitches that come up. 2. Automate Everything: Tap into automation tools to really simplify your deployment process. They'll help you save time and keep things running smoothly! This really helps cut down on mistakes and saves a lot of time. 3. Keep an Eye on the Rollout: Make sure to check in on how everything's going as we roll things out. If something’s about to go off track, it’s best to spot it early on.

Post-Deployment Steps

• Get Feedback: Once you’ve rolled things out, don’t hesitate to reach out to users and see what they think. Their input is super valuable! Hearing their feedback can really help you make the improvements you need.
• Stay on Top of Performance: Keep an eye on how your app is performing by checking its metrics. This way, you can make sure everything's running like it should.
• Plan for Updates: Just a heads up, rolling out the deployment is just the beginning of the journey! You'll want to fix any bugs that pop up and release updates whenever necessary.

Conclusion

I know deployment can feel pretty overwhelming at times, but with some thoughtful planning and a solid execution strategy, you can definitely make it a whole lot easier! Here are some tips to help you smoothly navigate the deployment landscape! Just keep these in mind, and you’ll be on the right track.

Heads Up on Enforcement Checkpoints for 2025-2026: Just a quick reminder to keep an eye on those enforcement checkpoints coming your way! Here’s the scoop: If you’re a manufacturer or repackager, mark your calendars for May 27, 2025. Wholesalers, you’ve got a bit more time, with an August 27, 2025 deadline. For the larger dispensers, make sure you’re all set by November 27, 2025. And for the smaller dispensers, breathe easy--you’ve got until November 27, 2026 to get everything sorted.
It's really crucial to nail down your upstream EPCIS data and ensure that your ATP credentials match up with the right partner class. If you want to dive deeper into the topic, you can check it out here. Happy reading!

• Vendor Conformance is Super Important: If you’re looking to stay on top of vendor conformance, you can’t go wrong with the GS1 US conformance trustmarks. They’re like your trusty sidekicks in this process! They really highlight how well your EPCIS file support is doing--saving you tons of time and hassle when you're going through those vendor assessments. If you're interested in learning more, you can find all the details right here.

What “Good” Looks Like in 6-9 Months:

So, in around 6 to 9 months, here's how we could measure our success:

1. Clear Milestones:

• It's important to have clear goals that are not only ambitious but also realistic enough to accomplish. Let’s make sure we’re touching base regularly to keep an eye on our milestones. It'll help us stay on the right path!

So, just a heads-up: by February 18, 2027, if you’re handling LMT/industrial batteries (you know, the ones that are over 2 kWh) or EV batteries in the EU, you’ll want to make sure you have a digital battery passport all set. It’s something you don’t want to wait on! You’ll be able to access this passport using a QR code, and just a heads up, the due diligence responsibilities will start on August 18, 2027. Just a quick heads up: the data needs to be easy for machines to read, work well with other systems, and be kept fresh and current. (eur-lex.europa.eu). So, here’s some exciting news from the early adopter side of things! Volvo has made a big move by introducing what they’re calling the world’s first EV battery passport for their EX90 model. How cool is that? This passport tracks where materials come from, how much recycled content is used, and the carbon footprint of the vehicle. It looks like each passport will set you back about $10. Not too bad, right? (reuters.com).

Blueprint:

• Identity model: Alright, so here’s the deal--we’re focusing on giving DIDs to various cells, modules, packs, and facilities. We’ll also have to get some VCs for things like tracking where the materials come from, auditing the smelters and refiners, and figuring out carbon declarations. No need to stress! If we ever need to take something back, we can easily handle it with Bitstring Status Lists. Take a look at this link: w3.org. It's got some cool info about the Verifiable Credentials 2.0 specs that just got the W3C stamp of approval!
• Chain-of-custody: Alright, let’s take a look at the ISO 22095 models. We can use them to clearly distinguish between identity-preserved and mass balance for each flow. So, when we’re talking about cobalt and nickel, which we really can’t escape from gathering together, it’s a good idea to include mass-balance confirmations using verifiable credentials. Plus, we should definitely think about doing regular physical audits to keep everything in check. For more info, check it out here: iso.org.
• Passport Store: We're going to set up an off-chain JSON-LD passport that meets the requirements of Regulation 2023/1542 Annex XIII. So, we have the ability to anchor version hashes right on the blockchain, which is pretty cool! Plus, the QR code will take people to a view that’s controlled by the audience. This means it could be accessed by the public, authorities, or anyone with a real reason to check it out. If you're interested in checking out the regulation, you can find it right here: eur-lex.europa.eu. Happy reading!

KPIs to Track:

If you want to gauge how well your business or project is doing, it’s really crucial to track the right KPIs (Key Performance Indicators). They can give you some valuable insights! Here are a few key ones that you might want to think about:

1. Customer Acquisition Cost (CAC)

• This shows you how much you're shelling out to attract each new customer. The formula is actually pretty simple!

  CAC = Total Costs of Sales and Marketing / Number of New Customers Acquired 

2. Customer Lifetime Value (CLV)

• This is all about figuring out the total revenue you can anticipate from each customer for as long as they stick around and do business with you. When your CLV is higher, it just means your customers are hanging around for a longer time!

3. Churn Rate

It can be really hard when customers decide to go, but keeping an eye on your churn rate can definitely help you understand things better. It's basically the percentage of customers who decide to stop using your service over a specific time frame. Keep things simple for a healthier business!

4. Net Promoter Score (NPS)

• This is an awesome way to get a handle on how happy customers are and how loyal they feel. It asks customers to rate how likely they’d be to recommend your company to their friends and family on a scale from 0 to 10. You're really going for those higher scores!

5. Monthly Recurring Revenue (MRR)

• If you run a subscription-based business, make sure you’re keeping an eye on your Monthly Recurring Revenue (MRR). It's super important to know how much money is rolling in each month! It gives you a pretty clear idea of the steady income you can count on each month. It's really great for making predictions!

6. Conversion Rate

• This highlights how effectively your marketing efforts are converting leads into actual customers. Keep tweaking your approach to really amp up those sales!

7. Website Traffic

Keeping track of how many folks are visiting your site can really help you understand how well your marketing is working.

Make sure to use tools like Google Analytics to keep an eye on this! It's really helpful for tracking what’s going on.

8. Engagement Rate

This is super important when it comes to social media. It really shows just how much users are engaging with your content! The more your audience gets involved, the better it is for everyone!

Wrap-Up

Keeping an eye on these KPIs regularly is a smart way to stay in tune with how your business is doing. It’ll help you make better decisions as you plan for the future! Hey, just a quick reminder: it's not enough to just gather data; you've got to actually put it to good use!

• Coverage: This refers to how many of the packs actually include complete origin and footprint claims. It also takes into account the percentage that have those handy third-party audit verification codes (VCs) included.
• Update latency: This is basically how long it takes for a passport to be updated after something happens, like when it’s manufactured, repaired, or reused.

Food and agriculture: FSMA 204 meets EUDR

• FSMA 204 Recordkeeping: You've got to hang onto and share some important info, called Key Data Elements (KDEs), for foods on the Food Traceability List (FTL). And don’t forget, you’ll need to provide those records within 24 hours if someone asks for them! The FDA's tech team is working on a setup that will take spreadsheets and convert them into the EPCIS format for their Product Tracing System (PTS). You don’t have to use EPCIS, but honestly, it really helps smooth out the process when it comes to interoperability. (fda.gov).
• Standards in the Stack: So, let's talk about GS1 EPCIS 2. The latest update now comes with sensor data and utilizes JSON-LD/REST! Also, GS1 US has some helpful guidelines that connect FSMA 204 Key Data Elements (KDEs) and Critical Tracking Events (CTEs) to GS1 identifiers, such as GTIN and GLN. (gs1.org).
• EUDR: Just a heads up, there are some new application deadlines coming up (make sure to look at the earlier section for all the details). Now, if you're dealing with commodities like coffee and cocoa, you’ll need to provide plot-level geolocation info.
  Get set to connect geospatial proofs to various plots of land using Verifiable Credentials (VCs). And don’t worry--we’ve got you covered on keeping farmers’ personal information safe with SD-JWT/BBS. (consilium.europa.eu).
• Mass Balance in Action: Unilever recently kicked off a pretty cool pilot project with SAP GreenToken, and guess what? They’ve managed to track more than 188,000 tons of palm oil by using this innovative tokenized mass balance method. Pretty impressive, right? This model works really well when it’s tough to have physical separation, but regulators are on board with a book-and-claim or mass balance system, as long as there are solid controls in place. (news.sap.com).

Architecture that wins audits and protects secrets

1. Data Plane

• Off-chain EPCIS 2. So, we're talking about an event store that includes stuff like CTEs and KDEs, along with sensor data and certification references.
• Think of it as a version-controlled document hub where we manage all sorts of important stuff like electronic birth licenses, passports, and certificates.

Integrity Plane

So, we're planning to use periodic Merkle roots for groups of events, and we'll be anchoring all of that to a public chain, like the Ethereum mainnet or one of the Layer 2 solutions. This setup makes it super hard to mess with things without racking up some serious costs. Plus, it does a great job of keeping personal info and business details safe and sound, away from the main chain.

3) Identity and Access

So, we’re diving into W3C DIDs, which are basically digital IDs for all sorts of stuff--think organizations, devices, and even shipments. Plus, Verifiable Credentials 2. Zero plays a key role in various areas, like ATP, exporting, and refining. It’s also essential for important compliance stuff, including claims about the country of origin and certification. Take a look at this: W3C Announcement. It's got some great info!

4) Privacy by Default

• SD-JWT (RFC 9901) is a cool way to share specific claims in JWT ecosystems, and there are plenty of tools available to make the process easier for you. The BBS+ Data Integrity Cryptosuite focuses on ensuring that proof presentations are unlinkable in JSON-LD ecosystems. Check it out here!.

1. Legal/Evidence

• Don’t forget to sign all your artifacts with the right organizational keys! Hey, just a quick reminder to make sure you jot down the hash, timestamp, and the signer’s DID. You don’t want to miss those important details! It's really crucial to keep up with MLETR jurisdictions because it helps ensure that electronic documents of title remain negotiable. Take a look at the details right here: (legislation.gov.uk). You’ll find all the info you need!

• Month 0-1: Getting Our Bearings with Regulations and Standards. First off, you'll want to dive into mapping out your lanes and products to different standards such as DSCSA, FSMA 204, EUDR, ETDA, and the Battery Regulations. This will help you keep everything organized and compliant! First things first, you’ll want to nail down your chain-of-custody strategy based on ISO 22095. You’ve got two solid options here: go for identity-preserved or stick with mass balance. Take a moment to think about which one fits your needs best! (iso.org).
• Months 2-3: Setting Up the Reference Architecture.
• Get started with the essentials using EPCIS 2. You’ve got a capture/REST API, a registry for DIDs and VCs, an anchoring service, and a gateway for verifying SD-JWTs and BBSs. (gs1.org).
• Months 4 to 6: Testing with Two Partners per Lane. Alright, so when it comes to shipping, let's stick to using DCSA eBL and Cargo Release at a single terminal. For our pharmaceutical stuff, we should really zero in on the EPCIS exchange along with an ATP VC. And for the batteries, let’s kick off a passport MVP, partnering with two suppliers to get things rolling. (dcsa.org).
• Months 7 to 9: Interop Hardening.
• Run some conformance tests for GS1 EPCIS, make sure the eBL works smoothly, and check the status of VC revocation. Also, consider doing a tabletop regulatory audit with actual data to get a clear idea of where you stand. (tracelink.com).
• Month 10-12: Scale-Out
  Alright, here’s the plan: let’s bring in 5 to 10 new suppliers. We need to streamline the credential issuance process so it’s all automated, and we should definitely get those Merkle anchors out to the public chain. Also, we’ve got to focus on solidifying our governance strategy--this includes everything from onboarding and fees to SLAs and data retention. Let’s make sure we’ve got all our bases covered!

Pitfalls to avoid (and what to do instead)

• Big-bang, all-on-chain designs: It's really about making sure data is stored where it should be--keeping events off the chain, while putting the proofs right on it. Just a heads up--regulators really care more about having solid evidence and getting the info to them on time instead of focusing on how much gas you're actually using.
• Don't overlook the legal framework: If your electronic bills of lading (eBLs) don’t fit in with the MLETR guidelines, you're basically just putting a band-aid on a bigger issue. It’s much better to aim for the MLETR/ETDA pathways right from the get-go. Trust me, it'll save you a lot of headaches down the road! Take a look at the details right here: (legislation.gov.uk).
• Ignoring conformance: When there are variations in EPCIS, it can really throw off interoperability. Don’t forget to ask for GS1 conformance testing right from the start - it’s a smart move that’ll help you avoid a ton of headaches down the road! If you want to dive deeper into this, check out more details here: tracelink.com.
• Single-sponsor networks: To maintain stability, it’s important to prioritize neutral governance. Make sure to publish APIs and set clear standards while also teaming up with a variety of solution providers. This helps keep the ecosystem from becoming too delicate. If you're looking for more details, just check this out: maersk.com. You'll get all the info you need!
