Revoka Protocol
A Technical Whitepaper
Abstract
Revoka is a decentralized privacy computing protocol designed to enable intent-centric private execution for AI agents, DePIN networks, and DeFi applications. By leveraging advanced cryptographic techniques including zero-knowledge proofs, secure multi-party computation, and ephemeral compute receipts, Revoka provides a modular privacy stack that preserves user privacy while maintaining computational verifiability.
This whitepaper presents the technical architecture, privacy mechanisms, consensus protocol, and economic model of the Revoka ecosystem. We introduce novel concepts such as revocable proofs and intent privacy that enable unprecedented levels of privacy control for users while ensuring network security and decentralization.
01Introduction
1.1 Background
The blockchain industry has witnessed exponential growth in decentralized applications, yet privacy remains one of the most critical unsolved challenges. Current blockchain networks expose transaction details, user intentions, and computational logic to the public, creating significant privacy and security concerns.
With the emergence of AI agents that require confidential computation, DePIN networks handling sensitive real-world data, and DeFi protocols processing private financial information, the need for robust privacy-preserving infrastructure has become paramount.
Key Insight: Traditional blockchain transparency conflicts with the privacy requirements of next-generation Web3 applications.
1.2 Motivation
Revoka was conceived to address three fundamental challenges in the current Web3 ecosystem:
Privacy Fragmentation
Existing privacy solutions are siloed and application-specific, lacking interoperability and composability across different use cases.
Intent Leakage
User intentions are exposed in transaction mempools, enabling MEV attacks, front-running, and privacy violations.
Computational Opacity
Smart contracts execute publicly, preventing confidential computation while maintaining verifiability.
1.3 Vision & Mission
Our vision is to establish Revoka as the foundational privacy layer for Web3, enabling a new era of confidential, intent-centric applications that preserve user privacy without sacrificing decentralization or security.
Privacy by Default
Make privacy the default setting for all Web3 interactions, not an afterthought.
Interoperability
Create a modular privacy stack compatible with any blockchain or application.
User Empowerment
Give users complete control over their privacy preferences and data disclosure.
Developer Friendly
Provide simple APIs and SDKs that make privacy integration effortless.
02Technical Architecture
2.1 System Overview
Revoka's architecture consists of four primary layers that work together to provide comprehensive privacy-preserving computation:
Application Layer
User-facing applications and smart contracts that utilize Revoka privacy features
Privacy Layer
Core privacy primitives including ZK proofs, MPC, and encrypted messaging
Consensus Layer
Validator network ensuring transaction finality and network security
Data Layer
Decentralized storage for encrypted data and compute receipts

2.2 Core Components
Intent Processor
The Intent Processor translates high-level user intentions into executable private transactions. It employs advanced cryptographic techniques to ensure intent privacy throughout the execution lifecycle.
// Generate ZK proof of intent
const proof = generateProof(intent)
// Execute privately
return executePrivate(proof)
}
Compute Receipt Manager
Manages ephemeral compute receipts that prove execution occurred without revealing computation details. Receipts expire after a configurable timeframe and can be revoked by the user at any time.
- Time-bound validity periods
- User-controlled revocation
- Cryptographic proof verification
- Audit trail for compliance
Privacy Router
Routes transactions through optimal privacy paths based on user requirements, network conditions, and cost considerations. Supports multiple privacy levels from basic to maximum.
2.3 Data Flow
A typical transaction in Revoka follows this flow:
User submits intent to the network
Intent Processor encrypts and generates ZK proof
Privacy Router selects optimal execution path
Validators verify proof without seeing intent
Private execution occurs in secure enclave
Ephemeral receipt is generated and returned
Result is decrypted only for authorized parties
03Privacy Technology

3.1 Intent Privacy
Intent privacy is the cornerstone of Revoka's architecture. Unlike traditional blockchains where transaction details are public, Revoka conceals the user's intended action until execution is complete.
Technical Implementation
Intent privacy leverages homomorphic encryption and zero-knowledge proofs to enable verifiable computation on encrypted data:
E(intent) → Encrypted intent submitted to network
ZK(E(intent)) → Zero-knowledge proof generated
Execute(ZK) → Private execution with proof verification
Result → Only visible to authorized parties
3.2 Ephemeral Compute Receipts
Ephemeral Compute Receipts (ECRs) are cryptographic proofs that demonstrate a computation occurred correctly without revealing the computation itself. They are designed to expire after a predetermined timeframe, enhancing privacy by preventing long-term data correlation.
Properties
- ✓ Time-bound validity
- ✓ Cryptographically verifiable
- ✓ Non-repudiable
- ✓ Privacy-preserving
- ✓ User-revocable
Use Cases
- • Proof of AI agent execution
- • DePIN service verification
- • DeFi transaction attestation
- • Compliance auditing
- • Cross-chain messaging
3.3 Revocable Proofs
Revocable proofs introduce a novel mechanism allowing users to invalidate previously issued proofs, providing unprecedented control over privacy disclosure.
Innovation: Traditional zero-knowledge proofs are permanent once issued. Revoka's revocable proofs can be invalidated by the prover, enabling "right to be forgotten" compliance and enhanced privacy control.
proof: ZKProof,
revocationKey: PublicKey,
expiryTimestamp: u64,
revoked: bool
}
3.4 Encrypted Messaging
Revoka provides end-to-end encrypted messaging between participants, enabling secure communication for AI agents, DePIN devices, and application users.
Encryption Scheme
Utilizes elliptic curve cryptography (Curve25519) with perfect forward secrecy:
- • Ephemeral key generation per session
- • Double ratchet algorithm for key rotation
- • Post-quantum resistant options available
- • Multi-party computation support
04Consensus Mechanism
4.1 Validator Network
Revoka employs a delegated proof-of-stake (DPoS) consensus mechanism with privacy-preserving validator selection. The network maintains a dynamic set of validators chosen through a cryptographically secure process that ensures both performance and decentralization.
4.2 Consensus Protocol
The consensus protocol combines the efficiency of DPoS with privacy guarantees through verifiable random functions (VRF) for validator selection. This hybrid approach achieves high throughput while preventing validator set manipulation.
Consensus Flow
// VRF-based validator selection
validator = selectValidator(VRF.prove())
// Block proposal
block = validator.proposeBlock()
// Collect votes
votes = collectVotes(block)
if (votes.count >= threshold) {
return finalizeBlock(block)
}
}
4.3 Transaction Finality
Revoka achieves instant finality through a Byzantine Fault Tolerant (BFT) consensus mechanism. Once a block receives confirmations from 2/3+ of validators, it is immediately finalized and cannot be reversed.
Finality Guarantee
Mathematical proof ensures that transactions cannot be reversed after finalization, even in the presence of malicious actors controlling up to 1/3 of the validator set.
