Frequently Asked Questions
Everything you need to know about building on Concordium.
Why Build on Concordium?
Concordium provides a secure, scalable, and regulatory-ready blockchain designed for real-world applications. With its built-in ID layer, predictable fees, and high-performance smart contracts, developers can build with confidence while ensuring compliance and privacy.
How Do I Get Started?
Start by exploring the developer documentation and setting up a development environment. Follow tutorials on writing smart contracts, interacting with the blockchain, and running a node.
What Programming Languages Are Supported?
Smart contracts on Concordium support multi-languages via WASM, but are currently only written in Rust using the Concordium smart contract framework. Off-chain applications can be built with any language that supports interaction with Concordium’s APIs and SDKs.
What Is the Concordium ID Layer?
The ID layer ensures that users and businesses can verify their identities while maintaining privacy. It integrates seamlessly with transactions, allowing compliance-ready applications without exposing unnecessary data.
How Does Concordium Handle Privacy?
Concordium uses zero-knowledge proofs (ZKPs) to preserve the privacy of user data, while ensuring that identity verification remains possible when required. This balances privacy with regulatory needs.
