Types of Blockchain That We Cover

Public Blockchains

Public blockchains provide open access and maximum transparency. As fully permissionless, decentralized networks, they allow anyone to join, validate, and audit transactions without prior approval. Octal IT Solution, a premier blockchain app development company, builds on industry-leading public chains like Bitcoin and Ethereum. We deliver robust dApp development, DeFi platforms, and NFT marketplace services. Our engineered blockchain solutions ensure unmatched security and global accessibility with no single point of control. Whether you are launching a cryptocurrency wallet, a decentralized exchange, or a tokenized ecosystem, we provide the expertise to scale.

Private Blockchains

Furnishing precision control for enterprise app development, Private blockchains are governed by a single organization, which grants network access exclusively to verified participants. As a Smart Contract Development Company, we extend deep into enterprise-grade platforms like Hyperledger Beau and Fabric, R3 Corda, ConsenSys Quorum, Canton Network, Ripple/XRP Ledger, Stellar, Hedera Hashgraph architecting solutions for internal supply chain management, payroll automation, and regulatory compliance workflows. When you hire dedicated blockchain app developers from our team, you gain specialists with expertise in high-speed design, blockchain infrastructures (confidential) that safeguard sensitive business data with immutability and auditability demanded by your operations.

Consortium Blockchains

Scale your network with federated blockchain architectures designed for secure, multi-party collaboration. Our expert Blockchain developers specialize in building robust consortium networks for banking alliances, insurance ecosystems, and global supply chains using industry-leading platforms like R3 Corda and B3i. If your industry requires data exchange and collective governance without sacrificing privacy, our tailored decentralized solutions deliver the high-performance infrastructure needed for complex enterprise partnerships.

Hybrid Blockchains

Aptly called as the Best of Both Worlds, Hybrid blockchains intelligently merge the transparency of public networks with the confidentiality of private ones giving enterprises full control over what data stays internal and what gets publicly verified. As specialists in hybrid architecture, you can hire dedicated blockchain app developers for building hybrid applications from our team or create networks like XDC and Dragonchain, or hire Polygon blockchain developers for scalable, cost-efficient hybrid deployments.

Enterprise Blockchains

There are some Managed Enterprise Services like Oracle Blockchain Platform, Amazon Managed Blockchain, and Kaleido which are designed for Consortium (Federated) Blockchains and Private (Permissioned) Blockchains. They focus on the needs of large enterprises, and are not publicly accessible. But these have shared governance among known participants.

Subdivision of Blockchain Developers

Blockchain technology has evolved from a specific financial tool to becoming a basis for all future BFSI transactions. When they are involved in full stack operations, they become proficient in both the core foundational aspects and front-end/back-end dApp development.

Cost to Hire a Blockchain Developer (Hiring Model)

The cost to hire a Blockchain Developer highly relies on app security, and long-term utility. When they create blockchain projects with ZK-Proofs or Rust-based chains (Solana/Near), they command the highest premiums which often exceed $200–$500/hr for audit-grade talent.

Cost to Hire a Blockchain Developer (Hiring Model)

Blockchain Developer Demand stems from the need of the companies to refit hype-era protocols for sustainability. Senior architects modernize legacy code to transition systems to more secure, production-ready environments without disrupting active total value locks.

Integration of decentralized modules into existing enterprise legacy systems requires a unique “Hybrid” developer who understands both traditional COBOL/JAVA backends and modern Smart Contracts to ensure IP security and seamless data flow.

Developer Per Hour (The Hourly Model) Fixed Cost Model Dedicated Team / Staff Augmentation
Junior Blockchain Developer ($12–$60) Hiring a developer (Blockchain) for creating an MVP (Basic Token/Simple Wallet): $5,000–$15,000. Offshore (India/Southeast Asia): $20–$80 per hour.
Mid-level Blockchain Programmer ($50–$120) Hiring a Blockchain Developer for a Medium sized Project (NFT Marketplace/dApp): $15,000–$50,000. Onshore (US/Western Europe): $100–$200+ per hour.
Senior/Audit-grade Coder ($100–$200+) Hiring a dApp developer for a Complex Enterprise project: $100,000–$300,000+. Hiring a blockchain developer on a monthly basis costs around $3,000–$15,000/month per developer, depending on geography and seniority.
Smart Contract Development Developer cost $8,000–$25,000. Hiring a blockchain developer on a monthly basis costs around $3,000–$15,000/month per developer, depending on geography and seniority.
Hiring a Small Dedicated Team of Blockchain Developers (2–4) costs around $8,000–$18,000+ per month.

Frequently Asked Questions

Costs depend heavily on smart contract complexity, audit requirements, and blockchain platform (Ethereum vs others). In simple terms:

  • US: $80–$200+/hour
  • UK: £60–£150/hour
  • UAE: $50–$150/hour
  • Offshore (India/LatAm): $20–$80/hour

Most companies regret going in-house too early due to high fixed costs and hiring delays. 

  • Choose in-house if you’re building a long-term Web3 product.
  • Choose outsourcing if you want faster launch and lower hiring risk.
  • Choose freelancers for short-term or experimental builds.

Speed matters because blockchain trends (like DeFi/NFTs) move quickly.

  • In-house: 4–12 weeks
  • Agency/outsourcing: 24–72 hours
  • Freelancers: 3–10 days

Without security expertise, projects are at risk. Many pages list tools—but buyers want clarity.

Look for:

  • Smart contract languages (Solidity, Rust)
  • Experience with dApps and wallets
  • Understanding of security and audits
  • Real project portfolio (not just GitHub samples)

This is why many businesses choose dedicated teams instead of individuals. If you’re building anything beyond a simple smart contract, you likely need:

  • Developer
  • QA/security auditor
  • Frontend (Web3 integration)
  • Backend/API engineer

This skill combination is rare globally, which drives pricing higher than typical software roles. Because they combine:

  • Cryptography
  • Distributed systems
  • Application development

For scalable apps, you usually need both roles. Sometimes but not always.

  • Smart contract developers focus on backend logic
  • Full-stack blockchain developers handle frontend + integration

Avoid hiring based only on resumes. This is a major trust gap.

Ask for:

  • Live deployed contracts
  • Security audit experience
  • Code samples reviewed by third parties
  • Experience with failures (important but rarely shared)

Most failures happen due to security negligence, not coding ability.

  • Poorly written smart contracts (can’t be fixed easily)
  • Lack of security audits
  • Overpromising on decentralization
  • No post-launch support

The timeline depends heavily on security, integrations, and testing.

  • Simple dApp: 4–8 weeks
  • Medium complexity: 2–4 months
  • Enterprise-grade: 6+ months
