Integrating Identity and Access Management in Blockchain with 7Block Labs

Your current IAM stack can’t “see” wallets, VCs, or smart accounts

• You’ve got your IAM setup standardized on OIDC/SAML + SCIM and are gearing up to roll out passkeys, but things are getting a bit complicated. Your procurement and asset workflows are diving into wallets, with partners using EU Digital Identity (EUDI) wallets and on-chain attestations that your Identity Provider just doesn’t get. In the meantime, teams are creating all kinds of smart wallets (4337s) and 7702-upgraded EOAs that slip right past your conditional access, logging, and revocation systems. It's not a lack of connectors that's the problem; your control plane simply doesn’t extend to verifiable credentials, SIWE sessions, or EVM policy enforcement. (fidoalliance.org)
• Keeping up with compliance is like trying to hit a moving target: W3C Verifiable Credentials 2.0 is officially a Recommendation now, which includes things like Data Integrity, JOSE/COSE, and Bitstring Status List. OpenID’s OpenID4VP/VCI is at 1.0, and self-certification kicks off in February 2026. Plus, NIST SP 800-63-4 is finalized with some solid guidance on “syncable” passkeys. Your auditors are nudging you about revocation, AAL mapping, and data minimization--stuff you really can’t prove across those wallets and chains. (w3.org)
• And don’t forget about those EU deadlines: EUDI Wallets are supposed to be a must-have for all member states by the end of 2026, with implementing acts rolling out through 2025. Vendors are going to start showcasing EUDI credentials (OID4VP/OID4VCI) for onboarding. If your verifiers and RPs can’t process them, you might find your procurement timelines slipping. (consilium.europa.eu)

Slippage, duplicate KYC cost, and audit exposure

• Missed deadlines: The EUDI flows are leaning on OpenID4VP/VCI and privacy-preserving presentations, which includes selective disclosure. If you don’t have verifiers and status checks set up, onboarding vendors can turn into a labor-intensive process--adding weeks to the timeline for each supplier. Mark your calendars: self-certification for OpenID4VP/VCI kicks off on February 26, 2026. If your verifier isn't compliant, you might face RFP penalties and get hit with “non-compliant” labels. (openid.net)
• Rising OpEx: Re-doing KYC for the same supplier across different business units keeps happening because those wallet-held credentials can’t be verified against your IdP/IGA policies. Sure, passkeys help cut down the help-desk workload and reduce login fails, but without the ability to reuse credentials and ensure machine-verifiable claims, you’re stuck repeating IDV checks. The FIDO Alliance found that 87% of enterprises deployed passkeys, enjoying better user experience and security--if you ignore this, expect higher abandonment rates and support tickets piling up. (fidoalliance.org)
• On-chain blind spots: With the introduction of smart accounts through EIP‑4337 and upgraded EOAs via EIP‑7702, we’re looking at delegated execution and simplified gas handling. If your Zero Trust policies aren’t able to assess verifiable claims at the contract boundary, you can't enforce the least privilege principle or gather SOC2/ISO 27001 evidence. And beware--if you’re verifying ZK proofs on-chain in a straightforward way (~500k gas), you’ll easily exceed your gas budgets and SLAs. (eips.ethereum.org)

7Block Labs’ Complete IAM for Blockchain: Audit-Friendly and ROI-Driven

7Block Labs has crafted a comprehensive Identity and Access Management (IAM) solution tailored specifically for blockchain technology. Our platform isn’t just about meeting standards; it’s designed to breeze through audits and deliver a solid return on investment (ROI).

We connect your enterprise IAM with decentralized identity and on-chain access, ensuring that security and procurement work hand in hand. Our method is all about being standards-first, audit-ready, and optimized for performance.

1. Architecture that your auditors will approve

• Credential model: Let's go with W3C VC 2.0 as our go-to format. Pick cryptographic profiles based on what kind of risks you're dealing with:
  • For data integrity, use EdDSA/ECDSA to keep things deterministic and ensure interoperability.
  • Use JOSE/COSE profiles (JWT‑VC/SD‑JWT‑VC) to make sure we're compatible with OIDC and can handle selective disclosure.
  • Opt for the Bitstring Status List for a privacy-focused, scalable revocation process. Check out more about it here.
• Protocol rails:
  • Issuance: Go with OpenID4VCI 1.0 to allow batch issuance, deferred credentials, and c_nonce binding. More info can be found here.
  • Presentation: Use OpenID4VP 1.0 along with DC‑API support for origin-bound responses to keep replay attacks at bay. Check it out here.
  • Federation: OpenID Federation 1.0 is in the works for cross-organizational trust metadata (currently being finalized). You can follow along here.
• Assurance mapping: Make sure to align your verifiers with NIST SP 800‑63‑4 (AAL/IAL), especially when dealing with syncable authenticators like passkeys. We'll document our AAL reasoning, authenticator flags (like UV, BackupEligible/State), and risk indicators to keep your auditors informed. Dive deeper into that here.

2) Enterprise IAM Interop, Not Another Silo

• Identity Provider Integration: We’re all about keeping things seamless. That means sticking with OIDC/SAML for your workforce and customers. We also connect verifiable credentials using OpenID4VP to fit right into your current policy engines. Plus, we’ve got SCIM 2.0 provisioning set up, so groups and roles in your IdP correspond to on-chain policy tags--and the other way around! This includes all those new SCIM events coming down the pipeline. Check out the details here.
• Passkeys and Wallets: Let’s level up security by linking WebAuthn passkeys to wallet sessions (thanks to SIWE per ERC‑4361) and verifiable presentations. This not only bumps up your login success rates, but also keeps session integrity strong while maintaining that AAL2+ security posture. Learn more here.
• EUDI Readiness: We’re on it! We set up verifier endpoints and RP registration that align with the EUDI ARF, so your portals will be all set to accept EUDI wallet presentations for supplier onboarding by the end of 2026. More info here.

3) On-chain Access Control That Embraces Zero Trust

• Account Abstraction with Audit Hooks:
  • We're leveraging EIP‑4337 smart accounts, which let you use policy-rich signatures, session keys, and paymasters;
  • EIP‑7702 allows EOAs to adopt smart account logic without the hassle of migrations. Plus, we put signer, policy decisions, and paymaster data right into your SIEM. Check it out here: (eips.ethereum.org).
• Contract-Level Verification:
  • Eager to ensure contract signature checks? EIP‑1271’s got you covered;
  • And with EIP‑6492, we can validate pre-deploy signatures for counterfactual accounts, ensuring you won’t hit any UX dead-ends before the first deploy. Here’s the link for more details: (eips.ethereum.org).
• Gas-Aware Design:
  • We aim to keep those pricey ZK verifications off-chain when we can. But if we absolutely must verify on-chain, we're focusing on precompile-friendly curves and proof aggregation, expecting around ~500k gas per SNARK proof baseline. We also handle revocation checks using bitstring status lists off-chain, with on-chain attest anchors to keep gas costs in check. For more info, dive into this: (ethereum.org).

4) Privacy by Design Without Compromising Procurement UX

• Selective Disclosure Options:
  • We have a couple of cool choices here: SD‑JWT‑VC works great for JWT-native stacks and OIDC;
  • For JSON‑LD contexts, BBS+ Data Integrity is your friend for unlinkable derived proofs. We’ll choose what fits best depending on the specific use case and privacy needs in different regions. (datatracker.ietf.org)
• Data Minimization:
  • When it comes to verifiers, they should only ask for the attributes they really need to make decisions about policies. For instance, it’s better to check if someone is “EU‑VAT verified” rather than pulling the entire certificate. And by binding presentations to the origin using the OpenID4VP DC-API, we can help cut down on replay risks. (openid.net)

5) Operate and Prove -- Logs, Metrics, and Controls for SOC2 and ISO 27001

• Control Library: We take the time to map out every single interface--whether it's issuance, presentation, contract checks, or paymaster sponsorship--to the SOC2 Trust Services Criteria and the controls outlined in ISO 27001 Annex.
• Observability: Our verifiable event pipelines are designed to push information on issuance, status, presentation, and on-chain policy decisions straight to your SIEM, complete with cryptographic proof to back it up.
• Revocation SLAs: We have Bitstring Status List publishers in place, with clearly defined RPO/RTO targets all laid out in your runbooks. Plus, we set up scheduled evidence to keep auditors happy. Check out more details here: (w3.org).

A) Supplier onboarding (EU-ready) with zero re-KYC

• Flow:
  1. Issuance: Your KYC provider kicks things off by issuing a Supplier-Verified VC through OpenID4VCI. It’s all signed with JOSE/COSE and then stored on a privacy-friendly Bitstring Status List, just in case we need to revoke it. (openid.net)
  2. Presentation: The supplier’s wallet shares info via OpenID4VP. The request is origin-bound (thanks, DC-API) and only asks for “VAT-number-verified:true, domicile:EU.” (openid.net)
  3. IAM Bridge: Our verifier takes that info and translates it into IdP session claims, while SCIM swoops in to tag the supplier’s organization record with an “EU-VENDOR” group. This automatically jumps into action for procurement workflows. (rfc-editor.org)
  4. Contract guardrail: Your on-chain purchase-order contract checks off ERC-1271 signatures and verifies an attested “EU-VENDOR” boolean in the call data (pulled from a fresh presentation). Plus, a 4337 paymaster handles the sponsorship to smooth out any gas fee hassles for the vendor. (eips.ethereum.org)
• Why this works now:
  • VC 2.0, Data Integrity, and the Bitstring Status List are all W3C Recommendations as of May 15, 2025. OpenID4VP/VCI will be finalized with a self-cert starting in February 2026, and the EUDI Wallet mandate is aiming for the end of 2026. You're right on track with the latest standards and timelines. (w3.org)

B) Workforce Passkeys + Wallet Sign-In, NIST-Aligned, with On-Chain Enforcement

• Flow:
  1. Employees log in using passkeys (AAL2). NIST SP 800-63-4 lays out the rules for “syncable authenticators” (think key backup and sync), and we keep a record of this for audit purposes. (pages.nist.gov)
  2. The app sends out an ERC-4361 SIWE message; for those smart accounts that aren’t deployed yet, ERC-6492 comes into play, allowing us to wrap signatures for verification before anything goes live (no dead ends here!). (eips.ethereum.org)
  3. When dealing with sensitive contract calls, we need an OpenID4VP presentation of a “Verified-Employee” VC along with group claims. The contract checks in via ERC-1271, and an off-chain verifier makes sure the VC is still good and fresh, pushing the results on-chain as a short-lived permit. (openid.net)
  4. EIP-7702 lets the employee’s EOA turn into a delegated smart account for the session, which means they can have sponsor-paid transactions (thanks to the 4337 paymaster) and batch operations. Plus, the SIEM gets signed logs for each policy decision made. (docs.cdp.coinbase.com)
• Why It’s Worth Doing:
  • FIDO data shows that passkeys have impressive conversion and success rates. Plus, Ethereum’s account abstraction is really taking off -- we're talking tens of millions of smart accounts and over 170 million UserOperations. This means your wallet experience is right in line with where the ecosystem is heading. (businesswire.com)

C) Cost-Controlled ZK Credentials When It Counts

• In some procurement scenarios, we need a level of unlinkability that goes beyond what SD-JWT offers, like with whistleblower channels or competitive bids. That’s where BBS+ Data Integrity comes in handy for unlinkable derived proofs. For those using JWT-native stacks, we stick with SD-JWT-VC. Plus, we steer clear of on-chain verification to dodge that hefty ~500k gas fee for each proof. When we absolutely have to use on-chain proofs--like during sealed bid openings--we plan to batch and aggregate the verification on Layer 2, then anchor the results back on Layer 1. (w3.org)

Implementation Details You'll Care About (Brief, In-Depth)

Brief Overview

Getting into the nitty-gritty of implementation can be overwhelming, but we’ve boiled it down to the essentials you really need to know. Here’s a quick rundown of the main points.

In-Depth Insights

Alright, let’s dive a bit deeper into these implementation details.

• Frameworks: Choosing the right framework is key. Think about your project goals, team skills, and long-term maintenance needs. Popular choices include React, Angular, and Vue.js.
• APIs: Make sure your APIs are well-documented. A solid API can make or break your project. Look for RESTful or GraphQL options based on your data needs.
• Databases: Picking the right database is crucial. Whether you go for SQL or NoSQL, consider scalability, data structure, and your team's expertise.
• Security Measures: Don’t skimp on security! Implement HTTPS, use proper authentication, and keep your software updated to protect against vulnerabilities.
• Testing: Test early and often. Automated tests can save you tons of headaches later on. Tools like Jest, Mocha, or Selenium are worth checking out.
• Deployment: Look into CI/CD pipelines for smoother deployments. This will help you streamline updates and minimize downtime.
• Monitoring: Keep an eye on performance and errors post-launch. Tools like New Relic or Sentry can help you stay on top of things.

Final Thoughts

By keeping these implementation details in mind, you can significantly improve your project’s chances of success. Remember, the key is to adapt these insights to fit your specific needs and goals!

• Policy Composition
  • Off-chain: OPA/Cedar checks out VC claims (like freshness, issuer trust, and the revocation bit) along with IdP attributes, then sends back a signed decision token.
  • On-chain: Contracts only accept calls if ERC-1271 gives the thumbs up on the SIWE, and a short-lived decision token hash is matched with an allowlist. If the status list endpoint isn’t reachable, it defaults to deny (fail-closed with override roles).
• Gas and Latency
  • We handle verification off-chain, only anchoring the essential facts on-chain and covering gas fees through 4337 paymasters. When on-chain proofs are needed, we collect and schedule them on L2 to keep things running smoothly within your SLOs. You can plan on around ~500k gas for each SNARK verification as a baseline. (ethereum.org)
• Credential Lifecycle and Revocation
  • For batch revocation and high-QPS checks, we use the Bitstring Status List; we publish to two regions with signed snapshots. If you’re working with JWT-based stacks, our SD-JWT-VC status providers play nicely with cache-aware verifiers. (w3.org)
• Federation and Discovery
  • We’ll get your verifier set up as a Federation entity (OpenID Federation 1.0) so that partners can easily discover JWKS, metadata, and policies programmatically. It mirrors how your OIDC operates now, but tailored for credentials. (openid.net)
