Add vendors: State Labs – Tx Shield (Private Payment), OpenTMP LLM (Collaborative Private AI), and Collab-Key (MPC-TSS Key Management) #7

JoeZYXStateLabs · 2025-10-11T07:36:09Z

This PR adds three vendor entries from State Labs to the Ethereum Foundation's Institutional Privacy Mapping.

1. Tx-Shield (Private Payments)

Tech: High Performance MPC; Audit-Key Protocol
Use case: Confidential settlement of stablecoins, RWAs, and bonds on-chain.
Transactions are visible only to stakeholders, while regulators can access details through granted audit keys.
Ensures institutional privacy and compliance with high-performance (~10k TPS) MPC execution.

2. OpenTMP LLM (Collaborative Private AI)

Tech: MPC-FL; Distributed Learning; Edge AI Acceleration; SFT; RLHF
Use case: Efficient, secure, and privacy-preserving large-model training and inference across distributed environments.
Combines federated learning and MPC-FL to keep data local while performing encrypted aggregation and joint model updates.

3. Collab-Key (MPC-TSS Key Management)

Tech: MPC; TSS (ECDSA 2PC / multi-party); Threshold Signatures
Use case: Distributed ECDSA signing for institutional wallets and custody.
Eliminates single-party key reconstruction and integrates with KMS for fast, production-grade signing.
Built upon our team’s peer-reviewed research presented at USENIX Security 2025, combining academic rigor with real-world performance.

Each entry represents a key component of State Labs’ privacy-preserving infrastructure—covering payments (Private Payments), AI collaboration (Private Collaborative AI), and key management (Collab-Key) — aligned with IPTF’s institutional privacy domains.

Adds State Labs’ OpenTMP LLM to the vendor map under the Collaborative AI / Federated Learning privacy domain. - Tech: MPC-FL with threshold-secure aggregation - Scope: privacy-preserving training & inference with data locality - Modules: Private / Efficient / Governable LLM

Adds State Labs’ Collab-Key to the vendor map under the Custody / Key Management domain. - Tech: MPC-TSS for distributed ECDSA signing (2PC & multi-party) - Problem: eliminates single-point key compromise - Integrates with KMS; production-grade throughput

This PR adds State Labs to the vendor map under the Private Payments domain. - Product: Tx Shield — regulator-auditable private payment layer - Tech: MPC-based encryption + threshold key control (TSS) - Use cases: confidential settlement for stablecoins, RWAs, bonds - Performance: ~10k TPS via optimized MPC execution

Hi @JoeZYXStateLabs
Thanks for your contribution! Could you please consolidate all three into a single vendor card? We try to keep one card per vendor for consistency.

Hi @JoeZYXStateLabs Thanks for your contribution! Could you please consolidate all three into a single vendor card? We try to keep one card per vendor for consistency.

Thank you for your prompt reply!
Updated as requested — all three solutions (Tx-Shield, OpenTMP LLM, and Collab-Key) have now been consolidated into a single vendor card.

Thank you for your contribution! Left some comments, but overall looks good as a first entry to me

+# State Labs – Privacy-Preserving Infrastructure
+
+State Labs develops regulared privacy-preserving infrastructure for institutional payments (Tx-Shields), Private AI collaboration (OpenTMP LLM), and MPC-TSS Key Management (Collab-Key).  
+Our three core solutions — **Tx-Shield**, **OpenTMP LLM**, and **Collab-Key** — address compliance, compute, and custody privacy challenges for regulated institutions.


Could we rewrite this in third person? E.g. State Labs having three core offerings etc

(Our is ambigous for most consumers)

+State Labs builds modular privacy layers/solutions for institutional finance and AI systems:
+- **Tx Shield** — a regulated private payment layer/solution built on MPC-based encryption and threshold key control.  
+It enables confidential settlement for stablecoins, RWAs, and bonds while ensuring regulator-auditable transparency.  
+Transactions are visible only to stakeholders, while regulators can access details through granted audit keys.


in this part, can you pls clarify how an investor is KYCed? and how asset issuance is done?

+Transactions are visible only to stakeholders, while regulators can access details through granted audit keys.
+
+- **OpenTMP LLM** — is a distributed edge AI training and inference framework designed for privacy-preserving large-language model collaboration. It combines federated learning and multi-party computation (MPC-FL) to keep data local while enabling encrypted aggregation and joint model updates. It powers collaborative, effcient, secure, and governable AI training across distributed environments.


how do we map this to institutional privacy? is this a new feature for institutions?

and how does this interact with Ethereum L1?

+
+- **Collab-Key** — is a high-performance MPC-TSS framework supporting both two-party and multi-party ECDSA signing.  
+It ensures that no single participant ever reconstructs a full private key, providing cryptographic resilience and institutional-grade security.  
+The system integrates seamlessly with existing KMS and client applications for fast, production-grade signing.


is this MPC-TSS for Bank, Investor, or for Regulator and how to incorporate it?

+It ensures that no single participant ever reconstructs a full private key, providing cryptographic resilience and institutional-grade security.  
+The system integrates seamlessly with existing KMS and client applications for fast, production-grade signing.
+
+Each module can operate independently or as part of a unified privacy-preserving stack across payments, compute, and custody.


can you pls add an example of how do you stack them together?

This section is a bit too general and does not add much information what has been in the introduction, can you pls elaborate?

Not sure what you mean here, but non-compliant on-chain system is not among the institutional usecases

+## Architecture
+### Tx-Shield
+Implements a high performance MPC-based private payment layer with threshold key control and an audit-key protocol for regulator visibility.  


is this technically a network? or a centrally controlled 2-3 nodes cluster?

+### OpenTMP LLM
+Distributed AI architecture using federated learning and multi-party computation （MPC-FL) with threshold-secure aggregation.

what is the concrete efficiency can we expect here?
