HieraChain - The Hierarchical Blockchain Enterprise Ledger

HieraChain - The Hierarchical Blockchain Enterprise Ledger

English | Tiếng Việt

Overview

HieraChain is an enterprise ledger built on hierarchical blockchain technology, designed specifically for business applications without any cryptocurrency concepts. Rather than being a general-purpose blockchain platform focused on digital currencies, HieraChain provides a secure, hierarchical ledger structure for managing business operations and processes.

This ledger implements a multi-layer hierarchical architecture where Main Chains supervise Sub-Chains, enabling scalable and secure business process management. All operations within the system are referred to as "events" rather than "transactions," emphasizing its focus on business applications.

Key Features

• Hierarchical Structure: Multi-layer architecture with Main Chains (supervisors) and Sub-Chains (domain experts).

• Consensus Mechanisms: Supports Proof of Authority (PoA), Proof of Federation (PoF), and Byzantine Fault Tolerant (BFT) consensus.

• High Performance: Columnar storage with Apache Arrow, hybrid caching, and parallel event processing.

• Reliability & Recovery: Durable transaction journaling, automated failure recovery, and state rollback capabilities.

• Comprehensive Security Architecture: An omnipresent, enterprise-grade security philosophy extending across the entire system lifecycle (not just a single module), built on 6 core pillars:

  • Authorization (ABAC Policy Engine & MSP)
  • Lockdown & Logging (Quorum-based Voting & Tamper-evident Logs)
  • Fault-tolerance (BFT & Federation)
  • Risk Analyzer (Real-time Z-score activity monitoring)
  • Encryption (AES-256-GCM for storage, Ed25519 for signatures)
  • Decentralized Zero-Knowledge Proofs (ZK Verifier for trustless chain anchoring)

Quick Start

Installation

Via PIP (recommended)

pip install HieraChain

From source (for development)

Traditional pip method:

git clone https://github.com/VanDung-dev/HieraChain.git
cd HieraChain
python -m venv venv
source venv/bin/activate  # Linux/macOS (or venv\Scripts\activate on Windows)

# Install dependencies and project in dev mode
pip install -e .[dev]

Modern fast method with uv (recommended):

git clone https://github.com/VanDung-dev/HieraChain.git
cd HieraChain

# Install uv if not installed
curl -LsSf https://astral.sh/uv/install.sh | sh

# Auto create venv + install ALL dependencies in one command
uv sync

source .venv/bin/activate

Basic Usage

from hierachain.hierarchical import HierarchyManager

manager = HierarchyManager()
manager.create_sub_chain("supply_chain")

# Add an event
manager.add_event("supply_chain", {
    "entity_id": "PROD-001",
    "event": "production_complete",
    "timestamp": 1703088000.0,
    "details": {"quantity": 100}
})

# Submit proof to main chain
manager.submit_proof("supply_chain")
