ARCHITECTURE OVERVIEW
Core Components of Our Encrypted Mempool Architecture
Our modular, enterprise-grade architecture for ZK-Rollup data availability is built on four foundational pillars. Each component is designed to deliver provable security, high performance, and seamless integration for your application.
01
Zero-Knowledge Proof Generation Engine
We implement custom zk-SNARK/STARK circuits to generate succinct proofs of transaction validity before data hits the public mempool. This ensures your transaction data remains confidential while guaranteeing computational integrity.
- Client Value: Protect sensitive trade logic and user data from front-running bots.
- Differentiator: Optimized circuits reduce proof generation overhead by up to 40% versus generic solutions.

Gas Cost Reduction
02
Threshold Encryption Layer
A distributed key management system using threshold cryptography (e.g., FROST, DKG) to encrypt transaction payloads. Decryption keys are split among a decentralized set of operators, eliminating single points of failure.
- Client Value: Achieve cryptographically guaranteed data privacy without trusting a single entity.
- Differentiator: Our implementation is formally verified and audited by leading security firms.

03
High-Performance Sequencer Network
A decentralized network of high-availability sequencers that order, encrypt, and batch transactions. Built for sub-second finality and 99.9% uptime, ensuring your application's performance is never compromised.
- Client Value: Maintain low-latency user experiences with enterprise-grade reliability.
- Differentiator: Geo-distributed nodes with automatic failover and load balancing.

Data Availability Committee (DAC) Integration
Seamless integration with leading Data Availability Committees (like EigenDA, Celestia) or our own optimized DAC. We manage the entire lifecycle of data attestation and availability proofs for your rollup.
- Client Value: Guarantee data is available for verification without the cost and complexity of Ethereum calldata.
- Differentiator: Multi-DAC support lets you choose the optimal balance of cost, security, and speed.

ZK-Rollup Encrypted Mempool
Frequently Asked Questions
Get clear answers on our encrypted data availability solution for ZK-Rollups, from implementation to security.
Our solution encrypts transaction data before it enters the mempool, preventing front-running and MEV extraction. It uses a threshold encryption scheme where validators hold key shares, ensuring data is only decrypted for inclusion in a ZK-proof. This maintains privacy during sequencing while guaranteeing data availability for fraud proofs, a critical requirement for validium and volition architectures.
