You're all set with info that's up-to-date as of October 2023. This includes cool stuff like verifiable credentials and zero-knowledge proofs. Plus, you’ll find some real-world examples featuring big players like Walmart, Volvo, De Beers, and GSBN. And on top of that, there’s a handy step-by-step rollout guide to help keep things running smoothly!

Blockchain Supply Chain Management 101: From Pilot to Global Rollout

Decision-makers aren't just after the latest trends; they really want a solid game plan that can hold up under scrutiny. They need something that can stretch across various regions and fit right in with what they already have--think systems like ERP, WMS, MES, PLM, and labeling stacks. It's all about finding that smooth integration! This guide dives into what's really working these days, what the actual regulations say, and how to plan for growth from 2026 to 2029.

Why now: compliance deadlines are becoming data deadlines

Hey there! Just a heads up about the new EU Battery Regulation. Beginning February 18, 2027, if you’ve got an electric vehicle, light means of transport (like e-bikes), or an industrial battery that’s over 2 kWh, you’ll need to get a battery passport. Pretty interesting, right? Just something to keep in mind! These passports will have all the important details about each model and unit, plus different levels of access control. If you want to dive deeper into it, just check it out here.

  • US FDA FSMA 204 (Food Traceability Rule): So, the FDA is considering pushing the timeline back by 30 months, but Congress has stepped in and asked them to hold off on any enforcement until after July 20, 2028. But here's the deal: Walmart isn’t just sitting on its hands! They’re asking suppliers to have their traceability data--think ASN/EPCIS--ready to go by August 1, 2025. It’s a clear signal for everyone in the industry to step up and get things rolling! Hey, if you're curious to learn more, you can find all the info here. It's definitely worth a look!
  • US DSCSA (Pharma): So, the whole deal with package-level interoperable traceability is changing up a bit. Instead of strict enforcement, they’re moving towards phased exemptions that will go on through 2025 and 2026, depending on who’s involved in the process. Once we get through the stabilization phase in 2023-2024, we should be all set for complete electronic EPCIS flows throughout the network. If you want to dive deeper into this, just check it out here. It's got all the details you need!
  • EU ESPR/Digital Product Passport (DPP): So, the ESPR officially started on July 18, 2024. And guess what? The Commission is gearing up to launch the main DPP registry by July 19, 2026. Exciting times ahead! Brace yourselves because product-specific delegated acts are set to kick in around 2027 or 2028. If you want to dive deeper into this topic, check it out here. There’s a bunch of great info waiting for you!
  • EU CBAM: So, just a heads up--transitional reporting is set to run until the end of 2025, and then the financial responsibilities will start in 2026. We're still waiting on the finer details, though! This really highlights how important it is to have trustworthy emissions data and confirmations from upstream sources. Find out more here.

Here’s the deal: your traceability system really needs to generate data that's not only easy to verify and compliant with standards, but also goes beyond just cranking out PDFs. Plus, it should fit in nicely with those regulatory evidence models we’re all familiar with.


Lessons from the field: what scaled, what stalled

So, here’s the scoop: the Maersk/IBM TradeLens project, which was trying to set up this global shipping data system, officially got put on hold in 2023. So, what’s the main point? When it comes to working together, having good governance and solid incentives for everyone involved is just as crucial as the technology we use. Hey, just a quick reminder: don’t rely solely on network effects. It’s super important to design with those in mind right from the start! (maersk.com).

Volvo is raising the bar with its new EV battery passport for the EX90, launching it almost three years ahead of when the EU says they have to. So, it’ll run you roughly $10 for each vehicle. This really shows that when everyone understands the scope and supply meets the demand, “passporting” can totally be effective. (reuters.com).

The GSBN is really making strides by concentrating on a particular product, like Cargo Release and eBL. They're also keeping things in line with open standards, like what DCSA offers. Plus, they're working on smooth integrations with terminals and carriers to help reduce any bumps along the way. (smartmaritimenetwork.com).

De Beers is really stepping up their game with Tracr! They're now keeping tabs on where diamonds come from, even those that are 0. 5 carats or larger. This really fits well with the G7 import rules, creating a strong “pull” from those regulations alongside a “push” driven by what consumers trust. (nationaljeweler.com).

So, what do they all have in common? Let’s keep our eyes on the prize! Start by honing in on the issue at hand, maybe tackle it by zeroing in on just one document or asset to begin with. It’s all about taking that first step!

  • Making sure we’re keeping up with industry standards, like DCSA eBL and GS1 EPCIS 2. 0, etc.).
  • We’ve got strong agreements in place to make sure we get reliable data from our upstream sources. We're taking a phased rollout approach, complete with clear and measurable service level agreements (SLAs). This way, we can track our progress and ensure everything runs smoothly!

The standards-first architecture we recommend

A Scalable Blueprint We Use at 7Block Labs:

  1. Keep track of and model events using GS1 EPCIS 2.
  • Let’s take a closer look at EPCIS/CBV 2! You’ve got everything you need to dive into the details about “what/when/where/why/how.” Plus, you’ll get the lowdown on sensor telemetry, JSON-LD syntax, and the ins and outs of REST capture/query APIs. It's all there for you! It's the top choice for companies in fast-moving consumer goods, pharmaceuticals, industrial sectors, and retail. Take a look at this: gs1.org. It's worth checking out!

2) Issue claims as W3C Verifiable Credentials (VC 2.0)

Alright, let me break it down for you: You can now take stuff like batch Certificates of Analysis (COAs), details about recycled materials, where they come from, and their carbon intensity, and turn all that into machine-verifiable credentials. These credentials can link back to EPCIS events and identifiers, making everything super organized and easy to track. Pretty cool, right? The awesome thing? VC 2! So, guess what? Version 0 just got the stamp of approval as a W3C Recommendation! This is super exciting because it means different systems can play nice with each other. Plus, it makes it easier to share only the info you want, and it really backs up those zero-knowledge (ZK) patterns we’ve been hearing so much about. Take a look at this link: (w3.org). You’ll find some interesting stuff there!

3) Anchor Integrity on a Chain That Works for You

When we're talking about keeping things safe and reliable, we're diving into some cool stuff like hash or evidence anchoring on public blockchains such as Ethereum, Polygon, and even Hedera. These are super important for ensuring that no one can deny any of their actions, which we call non-repudiation. On the other hand, private or consortium chains really shine when it comes to handling workflows and keeping data access in check.

If you're getting into ESG and MRV use cases, it’s pretty cool to see open-source tools like Hedera Guardian really shining right now! They're really simplifying how we handle tokenized attestations and policies. If you want to dive deeper into this topic, check it out here. You'll find some interesting insights!

Hey there! Exciting news coming your way with the “Sunrise 2027” initiative! You’ll soon be able to use 2D barcodes right at the point of sale or when you're getting care. How cool is that? With just a single scan, you can easily access traceability and product info that’s useful for regulators, retailers, and consumers alike. Plus, it ensures that access is kept right where it needs to be. Take a look at this: gs1us.org. You might find it really interesting!

5) Privacy by Design

  • Go ahead and dive into using DIDs and VCs, but remember to keep data minimization in your thoughts. It’s all about using what you need and nothing more! Hey, have you thought about using zero-knowledge proofs? They're a cool way to "prove something without actually showing it." For example, you could use them to confirm that your cobalt isn’t coming from any restricted sources or that your carbon intensity is kept below a certain limit. It’s a neat approach that keeps things secure while still giving you confidence in what you’re presenting! This way, you can keep your trade secrets safe and still stay on the right side of the rules.

A minimal, proven data stack

  • Identity: Let’s dive into decentralized identities (DIDs) for organizations, facilities, and devices. Plus, we've got the Public Key Infrastructure (PKI) governance all sorted out thanks to our consortium.
  • Event store: You can think of it like an EPCIS 2, just in a more user-friendly way. It's a zero repository that works with REST, making it super easy to capture and query data. We’ve connected our JSON-LD contexts with GS1 ontologies, and everything’s all set up nicely!
  • Evidence graph: So, in this section, we're diving into VC 2. 0 issuers and verifiers. This also includes info about your credential status and any revocation details.
  • Chain services: Here, we’re talking about things like hash anchoring, notarization, and smart contract registries. These tools help keep track of policies and claims in a more efficient way.
  • 2D Data Carriers: Take a look at GS1 Digital Link QR codes and DataMatrix codes on packages, cases, and the SSCCs for pallets.

Example EPCIS 2.0 ObjectEvent (JSON‑LD) with Sensor Reading

Let me share a cool example of how EPCIS 2.0 works. When you combine an ObjectEvent with a sensor reading, it really comes to life. This JSON-LD snippet has a ton of helpful info packed in!

{
  "@context": "https://ns.edc.eu/epcis/v2.0",
  "type": "ObjectEvent",
  "eventTime": "2023-10-10T12:00:00Z",
  "eventTimeZoneOffset": "+00:00",
  "epc": [
    "urn:epc:id:sgtin:0614141.107346.2023"
  ],

  },
  "source": {
    "id": "urn:epc:id:sgln:0614141.654321.0"
  }
}

Breakdown of the JSON-LD Fields

So, let me break down what all these terms mean in this situation:

  • @context: This part sets the scene and explains the special terms we're using.
  • type: This tells us that we’re looking at an ObjectEvent.
  • eventTime: This records when the event happens, and it's crucial for keeping everything on track.
  • eventTimeZoneOffset: This tells you the offset from the timezone.
  • epc: This is the special ID that makes this object stand out.
  • action: This part explains what’s going on--in this case, it’s all about adding something.
  • bizStep: This indicates the current stage that the object is in within the business process.
  • disposition: This gives us an idea of whether the object is available or not.
  • sensorElement: Here’s where we’ll dump all the sensor data.
  • epc: This is the ID for the sensor.
  • sensorMetadata: This has all the details about what kind of sensor it is and the units it's using to measure stuff.
  • sensorValue: This is the real-time reading from the sensor, which is currently at 25. 5°C here!).
  • eventTime: This is the timestamp that shows when the reading was recorded.
  • readPoint: This is the spot where the object was accessed or read from.
  • bizLocation: This is where the business event is happening.
  • Source: This is basically where the object came from.

Go ahead and use this template as a starting point for your own ObjectEvent creations! It's a great way to kick things off.

{
  "@context": [
    "https://ref.gs1.org/standards/epcis/2.0.0/epcis-context.jsonld"
  ],
  "type": "ObjectEvent",
  "eventTime": "2025-12-01T14:12:33Z",

    "value": "ISO22000-2025"
  }]
}

Example Verifiable Credential (VC 2.0) Referencing EPCIS Evidence

So, let’s chat about what a Verifiable Credential (VC) looks like. Here's a quick example for you. 0) This is what it could look like when it's connected to EPCIS evidence.

Credential Structure

{
  "@context": [
    "https://www.w3.org/2018/credentials/v1",
    "https://example.com/epcis-context"
  ],
  "id": "urn:uuid:12345678-1234-5678-1234-567812345678",
  "type": ["VerifiableCredential", "EPCISCredential"],
  "issuer": "https://issuer.example.com",
  "issued": "2023-10-01T12:00:00Z",
  "credentialSubject": {
    "id": "https://subject.example.com",
    "epcisEvidence": {
      "eventTime": "2023-09-30T10:00:00Z",
      "eventType": "ObjectReceipt",
      "businessTransaction": "urn:uuid:abcd1234-efgh-5678-ijkl-90mnopqrstuv",
      "action": "ADD",
      "quantity": {
        "value": 100,
        "unit": "KGM"
      }
    }
  },
  "proof": {
    "type": "RsaSignature2018",
    "created": "2023-10-01T12:00:00Z",
    "creator": "https://keys.example.com/keys/1",
    "signatureValue": "abcdef1234567890..."
  }
}

Breakdown of the Credential

  • @context: This refers to the important backgrounds that help make sense of the credential, like EPCIS.
  • id: This is a special ID that helps you uniquely identify the credential.
  • type: This tells you what kinds of credentials we're dealing with, including a special type just for EPCIS.
  • Issuer: This is basically the place or organization that hands out the credential.
  • issued: This is the date when the credential was created.
  • credentialSubject: This is where you'll find the key details of the credential, like:
  • id: This is basically the ID that links to the specific subject of the credential.
  • epcisEvidence: This section includes all the juicy details about the EPCIS event, like when it happened and what kind of event it was.
  • Proof: This includes info on how they're checking the credential, like what kind of signature it has and when it was made.

Here's a little example to help you see how to set up a VC 2. 0 with EPCIS evidence. You can definitely change it up however you’d like!

{
  "@context": ["https://www.w3.org/ns/credentials/v2"],
  "type": ["VerifiableCredential", "FoodTraceabilityAttestation"],
  "issuer": "did:example:retailer-123",
  "issuanceDate": "2025-12-01T15:00:00Z",

  }
}

Pilot-to-rollout playbook (12-18 months)

  1. Alright, let’s get started by diving into a regulatory use case, and we’ll hone in on a specific SKU family.

Alright, let’s start by connecting the dots between the evidence and the regulation. Alright, so here’s the plan: we've got to connect the dots between FSMA 204 KDE/CTE and EPCIS events. Just picture things like shipping, receiving, transforming, lot IDs, and locations. It’s all about getting that mapping right! Hey, just wanted to give you a quick heads-up! Walmart is now looking for EPCIS or ASN flows, even though the FDA has decided to pause enforcement for the time being. Take a look at this link: (public.walmart.com). You’ll find some really useful info on food safety requirements and traceability! So, let's talk about the DPP/Battery Passport content in relation to the requirements laid out in the Article 77 annex fields. It's really important to create different access levels, not just for the general public, but also for those who have a genuine reason to access the information. If you want to explore that topic further, you can check it out right here: (eur-lex.europa.eu). Enjoy!

2) Canonical Data Model and Identifiers

  • Stick with GS1 identifiers such as GTIN, GLN, and SSCC, and make sure to use EPCIS 2. 0 JSON-LD contexts. Just a quick reminder to set up some extensions for any sustainability or compliance features you’re looking to include! It’s a great way to keep everything in line. Hey there! If you’re sensing that retail exposure might be coming up soon, it’s a good idea to hop on the GS1 Digital Link train now. That way, your labels will stay on point for Sunrise 2027. If you want to dive deeper into this topic, just head over to gs1us.org for more info. You'll find everything you need to know there!

3) Integration Sprints

Let's connect ERP, MES, WMS, and TMS systems with EPCIS capture right at the point of action--like on the production line, in the warehouse, at the docks, and even with our 3PL partners. It’s a good idea to hold off on centralizing everything too quickly. Instead, try to grab the data right from the source. So, we need to serialize and label stuff as fast as our production line runs. We're focusing on case and pallet SSCCs here. And don’t forget to send out EPCIS updates whenever there’s a change in status!

4) Governance and Contracts

We really need to create a strong consortium charter that covers:

  • Data Rights: This is all about figuring out who can access different kinds of data, whether it’s raw info, hashed data, or credentials.
  • Evidence SLAs: In this section, we'll chat about what you can expect in terms of how quickly we respond and how thorough our responses will be.
  • Liability and Exception Workflows: In this section, we’ll go over what steps to take when you encounter mismatched serial numbers.

Also, let's go ahead and use VC 2. You're all set with 0 and DIDs for supplier attestations. This is definitely going to help us cut back on those endless KYC/QA cycles! If you’re curious to dive deeper, you can learn more about it here. Enjoy exploring!

5) Privacy Engineering

  • Keep Data Lean: Stick to W3C VC claims and steer clear of putting sensitive info on-chain. Instead, just anchor those hashes to a public chain to keep things neat and make auditing easier.
  • Use ZK Proofs: Consider using zero-knowledge proofs for those threshold checks. It’s like being able to show that you’re compliant with emission standards under the CBAM default, without spilling any of your trade secrets. Just a heads up to keep everything in sync with CBAM's final framework that’s set to roll out in 2026. (taxation-customs.ec.europa.eu).
  1. Field Validation and Scale Metrics.

In this section, we’ll dive into how we validate our findings in real-world settings and measure their effectiveness at scale. It’s all about ensuring what we’re doing in the lab translates well into actual practice and figuring out just how impactful our efforts are. Let’s explore the methods we use to check our results and what metrics we look at to see if we’re hitting the mark!

  • So, here’s the set of KPIs we’re launching:
  • We aim to keep the event completeness rate by CTE above 99% consistently.
  • Keep an eye on read rates for labels and any necessary rework, with a goal of keeping exceptions below 1%. We're aiming for our VC issuance latency to be under 2 seconds, which is pretty quick. Plus, we want our verification times to hit the p95 benchmark in less than 300 milliseconds. Fingers crossed that we can hit these targets!
  • We're seeing a shorter dispute cycle time compared to our baseline. We really need to speed up the recall drill simulation time. Right now, it takes us hours, and we’re hoping to trim it down to just a few minutes.

7) Gradual Network Expansion

When choosing suppliers, think about how critical they are by looking at factors like their regulatory exposure, order volume, and any risks related to UFLPA or CBAM. Let’s think about incorporating VC issuance into our contracts. Also, it would be great to put together some easy-to-use onboarding kits for them.


Emerging best practices for 2026-2029

  • Go for networks that ride on established standards. GSBN partnering with DCSA to standardize electronic Bill of Lading (eBL) is a fantastic move! They're really getting to grips with the actual paperwork headaches we face, and they’ve built a strong legal and technical framework to make it happen. It's all aimed at hitting that ambitious goal of 100% eBL by 2030 - pretty impressive, right? (dcsa.org).
  • Get ready for retailer rules before the regulators step in. Walmart's way of handling FSMA 204 really highlights how major retailers tend to set the pace. So, when you're putting together your EPCIS and VC flows, it’s super important to focus on what your customers need, not just what regulators expect. Keeping your customers in mind will help you stand out! (public.walmart.com).
  • Get DPP/Battery Passports on the same page as EPCIS/VCs.
  • Make sure to use EPCIS to track those lifecycle events, VC 2. You can use 0 for your claims along with the QR/GS1 Digital Link to easily access dynamic content. This combo will definitely help you comply with the Article 77 requirements for battery passports. (eur-lex.europa.eu).
  • Engineer responsible for the transition to 2D barcodes. Hey, just a quick heads up! By the end of 2027, you’ll want to make sure that your POS and POC scanners are all set to handle 2D codes. It’s definitely a good idea to start thinking about dual-marking--so, UPC plus 2D codes. And don’t forget, you’ll need to make sure that the data behind those codes is verifiable. Trust me, it’ll save you a lot of headaches down the road! (gs1us.org).
  • Think of forced labor and origin controls like using cryptography.
  • Make sure to put together selective-disclosure attestations for things like where products come from and checking suppliers; Tracr’s move towards being transparent about country of origin really showcases how industries are changing and adapting. (nationaljeweler.com).
  • Getting ready for carbon and CBAM. Hey there! It's time to dive into those VC-backed EPDs and make sure you're connecting those emissions claims to the EPCIS events. Also, just a heads up - you'll need to get ready for those certificate surrender obligations that kick in starting in 2026. (taxation-customs.ec.europa.eu).

Technical deep dive: permissioned, public, or hybrid?

  • Permissioned (Fabric, Besu):
  • Pros: You’ll have super detailed access control, which is great for keeping things secure. Plus, you can expect lower latency, meaning everything runs smoother and faster. It also gives you better control over any changes, especially in a business environment.
  • Cons: It can be a real challenge to build a solid network and keep everything neutral--just look at TradeLens for proof of that. On top of that, you’ve got the added hassle of governance to deal with, which can feel like an extra weight on your shoulders. (maersk.com).
  • Public/L2 (Ethereum/Polygon, Hedera):
  • Pros: You'll love the solid immutability it offers, and the way it stays neutral really helps too. Plus, it’s super easy for third parties to verify things, which is a big win. And let's not forget, the privacy features are really stepping up--just look at the advancements in zero-knowledge proofs and data integrity proofs!
  • Cons: There are definitely some costs that come with governance, like those pesky gas fees on mainnets. Plus, how the public sees things can really make a difference. And don't forget, you'll want to keep an eye on data exposure to avoid any issues.
  • Hybrid (our favorite choice): This method helps you store your data in EPCIS and VC stores, all while you use hashes to anchor everything and handle your registry and state management on a public blockchain. If you're interested, you can totally set up a consortium chain to manage your workflow! Check out Hedera Guardian for ESG and MRV. It really highlights how tokenized, policy-driven attestations can provide a clear, auditable lineage. Pretty interesting stuff! (dltearth.com).

Implementation details that prevent stalls

  • Data contracts over APIs: Alright, let’s dive into what EPCIS 2 is all about. Think of 0 and VC schemas like rock-solid contracts. They come with versioning and conformance tests to make sure everything's in check. This way, we can easily implement conformance gating to help onboard partners without any hiccups.
  • Managing exceptions right from the start: From the get-go, we really need to set up some reprocessing queues. This will help us manage those pesky mislabeled lots, any time mismatches, and those annoying duplicate serial numbers. Also, it's a smart move to monitor MTTR for those exceptions.
  • Label quality matters a lot: Alright, let’s make sure we pick the right printers and validators for the job. We also need to double-check the x-dimension, the quiet zones, and the substrate to ensure everything is on point. And hey, we shouldn't overlook the importance of in-line vision systems! They play a crucial role in making sure our scan rates stay on point downstream.
  • Identity hygiene: How about we set up a system to automatically issue and rotate DIDs and keys for our facilities and devices? It’ll make things a lot smoother! Let’s make sure we keep those revocation registries for our credentials up to date too.

Indicative rollout timeline (example)

  • Weeks 0-6: Let's start strong! We'll begin by figuring out the scope, diving into regulations, and drafting up some governance. Plus, we’ll tackle those data contracts (EPCIS/VC) to make sure everything's in place. And hey, it's finally time to choose our partners!
  • Weeks 7-14: Alright, it’s time to jump into integrations! We’re talking about systems like ERP, MES, WMS, and TMS. We’re going to get labels and serialization up and running soon, and we’ll kick things off by launching our first EPCIS events in the lower environments. Exciting times ahead!
  • Weeks 15-22: Let’s get started on launching our VC issuance and verification services! We’ll also be diving into hash anchoring and setting up those consent and access policies. Exciting stuff ahead!
  • Weeks 23-30: During this time, we’ll kick off a pilot program in one or two lanes. We'll put together a handy supplier onboarding kit, whip up some exception playbooks, and make sure our SLAs are just right. Alright, so here’s the plan for weeks 31 to 52: we’re going to roll things out one region at a time. We'll put together some evidence packs for DPP, CBAM, and our retailers. Plus, we’ll ramp up the dual-marking with 2D barcodes. Exciting stuff ahead!

Procurement checklist (RFP/RFQ essentials)

  • Standards Conformance: We're really focused on staying current with EPCIS/CBV 2. We're all set with capture/query and JSON-LD validation, plus we’re rolling with GS1 Digital Link. Oh, and let’s not forget VC 2! When it comes to issuing and verifying credentials, we usually go with option 0. And if we're talking about the maritime industry, we definitely use DCSA eBL. If you want to dive deeper into the details, just head over to gs1.org. You'll find everything you need there!
  • Performance: We’re all about keeping things quick and efficient! Our target is to ensure that 95% of our data captures come in under 500 milliseconds. Plus, we want to manage over 1,000 events every second at each site and keep our reliability at an impressive 99%. You’ll have 9% availability, plus the option for offline buffering.
  • Security & Privacy: We really prioritize security here. We've got solid key management in place, along with holder-bound credentials, and we also support ZK/SD-JWT. We also make it a point to maintain detailed audit trails using hash anchoring.
  • Interoperability: So, we've got these REST APIs set up with OpenAPI specs, which is pretty cool. Plus, we also run event and VC conformance test suites as part of our CI process. It really helps keep everything in check! On top of that, we’ve made it super simple to export evidence for regulators.
  • Governance: We've got a pretty robust governance framework in place. It covers things like data ownership clauses, steps for revoking or expiring credentials, a comprehensive incident response plan, and it even allows third parties to come in and do audits.

Case mini‑patterns you can emulate

  • Pharma (DSCSA): Buckle up, because EPCIS 2 is on its way! 0 and VC 2. It's really all about getting serialized data to play nicely together. Since the phased exemptions are set to finish up in 2025/2026, it’s a smart move to start honing your exception resolution skills sooner rather than later! Want to dive deeper into this topic? Head over to the FDA website for more info!
  • Food (FSMA 204 + retailer mandates): So, here’s the deal: the FDA is taking a breather from enforcement until 2028. But honestly, don’t just sit around and wait for that. It’s a great time to dive into getting your EPCIS KDE/CTE coverage and sorting out the ASN/EPCIS dual-path. Trust me, getting on top of those retailer demands now will pay off down the road! If you want to dive deeper into this topic, check out the FDA's website. They’ve got tons of info laid out for you!
  • Automotive/EV batteries (Battery Passport): So, let’s dive into how we can model data that's specific to battery packs and explore the different levels of access available. First things first, let's dive into those supplier attestations (you know, the VCs) and check out those hash-anchored records. Also, it’s worth keeping an eye on what Volvo is up to with their cost and operational strategies--it's a great benchmark to consider! Check out this article from Reuters for more details on the topic! They dive into how Volvo is rolling out the world’s first EV battery passport. This is a big deal, especially with the EU’s new rules coming up in 2024. It's pretty exciting to see how companies are stepping up to meet these regulations!
  • Shipping (eBL): Just a heads up, make sure you're on the same page with DCSA eBL standards! Connecting with a network like GSBN is definitely a savvy choice. They're already on top of these standards and have built connections with terminals, so it makes things a lot easier! If you're looking for more information, check out DCSA. They've got some great insights waiting for you!
  • Luxury/minerals (origin & due diligence): When you're creating proof of origin documents, it's really important to keep them scalable for both consumer and customs inspections. Tracr's decision to streamline their operations to a single country of origin is a really solid example of a clear goal to aim for. If you want to learn more, go ahead and check out National Jeweler. There’s some interesting info there!
  • ESG/CBAM/DPP: Have you considered tokenizing attestations using open MRV tools like Guardian? It could be a game-changer! Plus, you can connect these to EPCIS lifecycle events that really add value to the DPP content. Just a thought! If you want to dive deeper into the topic, check out DLT Earth for some great info!

What to measure quarter by quarter

  • Q1: We're shooting for more than 95% completeness with our pilot CTEs. We're also looking to keep labeling exceptions below 2%. Plus, we want our credential verification to hit that sweet spot--95th percentile--under 300 milliseconds. For Q2, we're aiming to get about 50-70% of our suppliers onboarded in the pilot category. Plus, we’ve made some solid progress by cutting down the mean time to recovery (MTTR) for recall drills by 50% from where we started. So, for Q3, we’re planning to expand regionally with at least three sites. Our goal is to have dual-marked 2D codes on about 80% of the SKUs we’re focusing on. Oh, and we’ll also be putting together those CBAM/DPP evidence packs along the way! Alright, so for Q4, we really need to crush that external audit. It’s super important that we can show traceability evidence that connects everything--from the hash all the way back to the raw materials. And if it falls within our scope, we'll also have those consumer-facing scans up and running smoothly. Let's make this happen!

Final thought: de‑risk by building on standards that outlive platforms

When looking ahead to 2026-2029, it’s a great idea to consider “blockchain in supply chain management” as a way to automate evidence gathering. It’s all about making things smoother and more efficient! Here's how that looks:

  • Use EPCIS 2. 0 for event truth.
  • Implement VC 2. 0 for verifiable claims.
  • Make use of public-chain anchoring to ensure everything's easy to audit. Use 2D barcodes to make last-mile access easier!
  • And hey, make sure you’re using zero-knowledge patterns to protect the really important stuff!

We've got this stack ready to tackle both our current responsibilities and what’s on the horizon, like DSCSA, FSMA 204, Battery Passport/DPP, and CBAM. On top of that, it offers great opportunities for growth in industries like food, pharmaceuticals, shipping, and minerals. If you need a thorough evaluation, 7Block Labs can get started on a two-week “evidence architecture” sprint for you. They'll assist you in drafting your data contracts, figuring out the regulations, and putting together a plan to make the transition smooth.
