What is a blockchain development company?

A blockchain development company designs, builds, and maintains custom decentralized applications, node networks, and smart contracts. They help businesses implement cryptographically secure systems, tokens, and multi-chain architectures to establish distributed database ecosystems.

How much does it cost to build a custom blockchain app in 2026?

The cost typically ranges from $30,000 to over $250,000, depending on structural complexity. Minimal decentralized applications or Telegram mini-apps are more affordable, whereas enterprise-grade, multi-chain architectures with deep security audits require a larger engineering investment.

What is the difference between public and private blockchains?

Public blockchains, like Ethereum, are open-access networks where anyone can view and validate transactions. Private blockchains are permissioned environments controlled by one or more organizations, offering faster processing times, enhanced data security, and restricted network access.
