Tezos in the Context of DevSecOps: A Comprehensive Tutorial

1. Introduction & Overview

What is Tezos?

Tezos is an open-source blockchain platform for assets and applications that can evolve by upgrading itself. It is designed to provide a formal, secure, and decentralized governance process that supports smart contracts and dApps (decentralized applications).

Key Attributes:

• Self-amending ledger
• Formal verification
• On-chain governance
• Smart contract support using Michelson language

History or Background

• Founded: 2014 by Arthur and Kathleen Breitman
• Initial Coin Offering (ICO): 2017, raised $232 million
• Launch: Mainnet launched in 2018
• Goal: To create a secure and upgradable blockchain ecosystem, avoiding hard forks through an integrated governance mechanism

Why is it Relevant in DevSecOps?

Tezos brings formal verification and automated governance to the DevSecOps ecosystem. These capabilities align with core DevSecOps values:

• Security by design via formal smart contract verification
• Decentralized automation through on-chain governance
• Immutable audit trails for regulatory and security compliance
• Seamless CI/CD integration for blockchain-based apps

2. Core Concepts & Terminology

Key Terms and Definitions

Term	Definition
Baking	The process of validating and adding blocks to the Tezos blockchain
Michelson	A stack-based, statically typed language used for writing Tezos smart contracts
FA1.2 / FA2	Tezos token standards, similar to Ethereum’s ERC-20 and ERC-1155
Governance Protocol	Mechanism enabling stakeholders to propose and vote on upgrades
SmartPy	A Python-based smart contract development framework for Tezos

How It Fits into the DevSecOps Lifecycle

DevSecOps Phase	Tezos Role
Plan	Governance proposals are recorded on-chain and influence roadmap decisions
Develop	Smart contracts with formal verification are created using SmartPy or LIGO
Build	Contracts are compiled and tested using CI tools
Test	Formal verification ensures correctness before deployment
Release	Decentralized deployment on Tezos blockchain
Operate	Tezos nodes and smart contracts are monitored and upgraded through governance
Monitor	Logging and auditability through blockchain’s immutable nature
Secure	Secure-by-design architecture; formal proofs prevent vulnerabilities

3. Architecture & How It Works

Components

• Nodes: Full nodes maintain the blockchain and participate in consensus
• Bakers: Validators who create and verify blocks
• Smart Contracts: Written in Michelson or higher-level languages like SmartPy, LIGO
• Governance Mechanism: Includes proposal, exploration, testing, promotion, and adoption phases
• RPC Interface: Enables interaction with Tezos through RESTful APIs

Internal Workflow

1. Proposal Phase – Developers submit protocol upgrade proposals
2. Voting Cycle – Stakeholders vote on the proposal
3. Testing Period – Approved protocols go through sandbox testing
4. Promotion Vote – Final vote before activation
5. Adoption – Protocol is automatically upgraded

Integration Points with CI/CD or Cloud Tools

Tool	Integration
GitHub Actions	Smart contract testing, compilation, deployment
GitLab CI/CD	Automating governance proposals and voting
Jenkins	Pipeline to build, test, and deploy contracts
Docker/Kubernetes	Run Tezos nodes in containerized environments
AWS/Azure	Host Tezos nodes with monitoring and scaling

4. Installation & Getting Started

Basic Setup or Prerequisites

• Linux/macOS environment
• Docker and Docker Compose
• Python 3.x (for SmartPy)
• Tezos client or Octez binary

Step-by-Step Setup

1. Clone Octez Docker repo

git clone https://gitlab.com/tezos/tezos.git
cd tezos

2. Start a sandbox node using Docker

docker compose up -d

3. Install SmartPy for contract development

pip install smartpy-cli

4. Compile and test a simple SmartPy contract

# contract.py
import smartpy as sp

class HelloTezos(sp.Contract):
    def __init__(self):
        self.init(message="Hello")

    @sp.entry_point
    def update(self, new_msg):
        self.data.message = new_msg

Compile:

smartpy-cli compile contract.py output/

5. Interact with Node via RPC

curl http://localhost:8732/chains/main/blocks/head

5. Real-World Use Cases

DevSecOps Scenarios

1. Immutable Compliance Logs
   • Store logs or compliance checks on Tezos blockchain for audit-proof evidence
2. Decentralized Governance for CI/CD Pipelines
   • Dev teams vote on releasing certain updates to production via on-chain governance
3. Tokenized Access Control
   • Use FA2 tokens to manage developer roles and infrastructure access
4. Supply Chain Code Verification
   • Smart contracts enforce the authenticity and traceability of software components

Industry-Specific Examples

• Finance: Verified contracts for DeFi apps
• Healthcare: Patient consent and audit trails on blockchain
• Government: Transparent and automated approval workflows
• Cybersecurity: Smart contract-based vulnerability disclosure mechanisms

6. Benefits & Limitations

Key Advantages

• Formal Verification: Mathematically proves correctness
• On-Chain Governance: Reduces the need for hard forks
• Energy-Efficient: Uses Liquid Proof-of-Stake
• Decentralization: Aligns with zero-trust DevSecOps principles

Common Challenges

• Learning Curve: Michelson and SmartPy can be complex
• Tooling: Less mature ecosystem compared to Ethereum
• Governance Delays: Voting cycles introduce latency in upgrades

7. Best Practices & Recommendations

Security Tips

• Use formal verification before deploying smart contracts
• Validate governance proposals through sandbox testing
• Run Tezos nodes in isolated, monitored containers

Performance & Maintenance

• Regularly update nodes with protocol upgrades
• Optimize smart contracts for gas efficiency
• Monitor node health using Prometheus or Grafana

Compliance Alignment
