Revoka Whitepaper

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:

1

Application Layer

User-facing applications and smart contracts that utilize Revoka privacy features

2

Privacy Layer

Core privacy primitives including ZK proofs, MPC, and encrypted messaging

3

Consensus Layer

Validator network ensuring transaction finality and network security

4

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.

function processIntent(intent: Intent) {
// 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.

Basic
Fast & Low Cost
Standard
Balanced
Maximum
Ultimate Privacy

2.3 Data Flow

A typical transaction in Revoka follows this flow:

1

User submits intent to the network

2

Intent Processor encrypts and generates ZK proof

3

Privacy Router selects optimal execution path

4

Validators verify proof without seeing intent

5

Private execution occurs in secure enclave

6

Ephemeral receipt is generated and returned

7

Result is decrypted only for authorized parties

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

1
Proposal
Selected validator proposes new block
2
Validation
Validators verify transactions and proofs
3
Voting
Validators vote on block validity
4
Commitment
2/3+ validators commit to block
5
Finalization
Block is finalized and added to chain
// Consensus pseudocode
function consensus() {
  // 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.

Safety: P(reversal) < (1/3)^n where n = validator count
