SABLE — The Invisible Engine of Global Trade

Private Payroll & Invoice Management on Aleo Blockchain

100% Financial Privacy. 100% Audit Compliance.

🎯 Project Overview

SABLE is a mainnet-ready B2B infrastructure that provides zero-knowledge payroll processing for corporations. Built on Aleo, it encrypts employee salaries, positions, and identities while maintaining full regulatory compliance through selective disclosure mechanisms.

🏗️ Architecture

Modular Leo Programs (< 100KB each)

• sable_identities.leo - Employee identity management with encrypted records
• sable_treasury.leo - Corporate treasury with multi-sig authorization
• sable_payroll.leo - Private salary distribution with batch processing (30 employees/tx)

🔑 Key Features

1. Batch Payroll Distribution

• Batch Size: 30 employees per transaction (Aleo's 32-transition limit)
• Client-Side Queuing: Automatic partitioning with progress tracking
• ZK-Proof Generation: Real-time UI feedback for each batch

2. Selective Transparency (View Keys)

• Wave 1-2: Per-auditor view keys with time-limited access (Option A)
• Wave 5+ (Planned): Hierarchical Deterministic derivation for department-level visibility (Option B)
• ZKP Tax Proofs: prove_total_tax transition generates compliance proofs without revealing individual salaries

3. Enterprise-Grade UI

• Design System: Deep grays, white, subtle shadows (no crypto clutter)
• Proof Generator Modal: Visual ZK-circuit solving steps
• Tech Stack: Next.js 14, pnpm, Turborepo, Framer Motion

🚀 Quick Start

Prerequisites

• Node.js >= 20.0.0
• pnpm >= 9.0.0
• Aleo CLI (for Leo program development)

Installation

# Install dependencies
pnpm install

# Start development dashboard
pnpm dev

# Build all packages
pnpm build

# Lint all code
pnpm lint

Leo Program Development

cd leo-programs/sable_payroll

# Compile Leo program
leo build

# Run tests
leo run distribute_private_payroll

# Deploy to testnet
leo deploy --network testnet

📊 Aleo Protocol Limits

Constraint	Limit	SABLE Strategy
Max Program Size	100 KB	Modular programs (3 separate .leo files)
Max Mappings per Program	31	Data packing techniques
Max Transitions per Transaction	32	Batch size of 30 employees
Max Transaction Size	128 KB	Optimized data types

🛣️ Roadmap

• Wave 1-2: Core payroll distribution with per-auditor view keys
• Wave 3-4: Invoice management and multi-currency support
• Wave 5+: Hierarchical view keys for department-level granularity
• Mainnet: Security audit → Testnet validation → Mainnet deployment

🧪 Deployment Strategy

Phase 1: Testnet (Current)

# Deploy identity management
cd leo-programs/sable_identities
leo deploy --network testnet

# Deploy treasury
cd ../sable_treasury
leo deploy --network testnet

# Deploy payroll
cd ../sable_payroll
leo deploy --network testnet

Phase 2: Mainnet

1. Security Audit: Third-party smart contract audit
2. Synthetic Testing: 1000+ employee dataset on testnet
3. Gradual Migration: Pilot with 1-2 enterprises
4. Full Launch: Public mainnet deployment

🔐 Security Considerations

• Private Keys: Never exposed; all ZK proofs generated client-side
• View Keys: Time-limited with cryptographic expiration
• Record Encryption: Aleo's native encryption for all salary data
• Audit Trail: Public mappings for compliance without revealing private data
