1. What Is Public Blockchain Development?

Public blockchain development refers to designing, coding, and deploying applications, smart contracts, and protocols on decentralized, open-access networks. These networks are permissionless—anyone can join, validate transactions, and build applications.

• Ethereum: The most widely adopted smart contract platform.
• Solana: High-performance blockchain with low fees.
• Polkadot: Designed for interoperability and cross-chain communication.
• BNB Chain: Optimized for scalability and DeFi ecosystems.

2. Why Businesses Choose Public Blockchains

• Transparency: Every transaction is recorded on an immutable ledger.
• Security: Consensus mechanisms like Proof of Stake (PoS) secure the network.
• Interoperability: Public networks support cross-chain development.
• Innovation: Open-source communities drive faster upgrades.
• Global Reach: Anyone worldwide can interact with your dApp or token.

3. Core Features of Public Blockchain Development Services

• Smart Contract Development: Custom contracts for DeFi, gaming, supply chain, or tokenization.
• dApp Development: User-friendly decentralized applications across industries.
• Blockchain Consulting: Roadmaps and strategy for blockchain adoption.
• Node Deployment & Infrastructure Setup: Running validator or full nodes.
• Blockchain Interoperability Solutions: Bridges and APIs for cross-chain communication.
• Security Audits: Penetration testing, bug fixing, and compliance checks.
• Integration with Existing Systems: ERP, CRM, or inventory management system integrations.

4. Key Platforms for Public Blockchain Development

Ethereum Development Services

Rich ecosystem of dApps, DeFi protocols, and NFT marketplaces. Hire blockchain developers for Ethereum to create custom tokens (ERC-20, ERC-721).

Solana Development Services

Known for high throughput (65,000 TPS). Hire blockchain developers for Solana when speed and low fees matter.

Polkadot Development Services

Built for interoperability. Enables parachains and cross-chain messaging.

BNB Chain Development Services

Supported by Binance ecosystem. Ideal for DeFi, NFT, and Web3 projects targeting mass adoption.

5. Smart Contract Development for Public Blockchains

• Writing and deploying smart contracts on Ethereum, Solana, or Polkadot.
• Token standards (ERC-20, ERC-721, ERC-1155, SPL tokens).
• Audit and verification of smart contracts for vulnerabilities.
• Building DeFi protocols (DEXs, lending platforms, staking pools).

6. Decentralized Application (dApp) Development

• Launch NFT marketplaces.
• Build DeFi platforms for lending, borrowing, and trading.
• Create decentralized identity (DID) systems.
• Enable Web3 social networking platforms.

For example, companies creating social apps can integrate social networking app development with blockchain for user ownership and monetization.

7. Blockchain Interoperability Solutions

• Polkadot parachains enable chain-to-chain interaction.
• Wrapped tokens let assets move between ecosystems.
• APIs connect blockchains to enterprise tools like modern ERP solutions or custom CRM development.

8. Open-Source Blockchain Development

Most public blockchains are open-source, offering faster innovation, transparency, lower costs, and easier integration.

9. Public vs. Private Blockchain

10. Industries Leveraging Public Blockchain Solutions

• Finance/DeFi: Lending, staking, asset management.
• Supply Chain: Logistics with supply chain software development.
• Healthcare: Data security with healthcare software development.
• Insurance: Automated claims with smart contracts.
• Entertainment: NFT ticketing, streaming rights.
• Education: Credential verification via education app development.

11. Steps to Build on a Public Blockchain

1. Define objectives (DeFi, NFT, supply chain, identity).
2. Select the right platform (Ethereum, Solana, Polkadot, BNB Chain).
3. Engage a public blockchain development company.
4. Design architecture and tokenomics.
5. Develop and audit smart contracts.
6. Build user-friendly front-end interfaces.
7. Launch beta testing on testnet.
