Find answers to common questions about blockchain, smart contracts, and our services.
Blockchain is a distributed ledger technology that maintains a continuously growing list of records called "blocks." Each block contains a cryptographic hash of the previous block, creating an immutable chain. It enables secure, transparent, and decentralized record-keeping without requiring a central authority.
Blockchain uses cryptographic hashing, digital signatures, and distributed consensus mechanisms. Each block is cryptographically linked to the previous one, making it computationally impractical to alter past records without detection. The distributed nature means no single entity can control or manipulate the entire chain.
Public blockchains are open to anyone and fully transparent. Bitcoin and Ethereum are examples. Private blockchains require permission to join and are typically controlled by specific organizations. They offer faster speeds and greater privacy but less decentralization.
Smart contracts are self-executing programs stored on blockchain that automatically enforce agreements when predefined conditions are met. They eliminate intermediaries, reduce costs, and enable transparent, deterministic execution. Once deployed, they cannot be altered (immutability).
No. Solidity is the most popular for Ethereum and EVM-compatible chains, but other languages exist: Rust (Solana), Move (Aptos, Sui), Go (Hyperledger), and others. The choice depends on the blockchain you're targeting.
Use testing frameworks like Hardhat, Truffle, or Foundry. Write unit tests for each function, test edge cases, and simulate various scenarios. Always test on testnets before deploying to mainnet. Professional audits are recommended for production contracts.

Yes! We offer security consulting and smart contract auditing services. Our team can review your code for vulnerabilities, suggest optimizations, and provide recommendations for production deployment. Contact us for detailed information about our audit services.
Support varies by plan. Starter plans have access to community forums. Professional plans include direct support channels. Enterprise plans offer dedicated support teams. Contact us to discuss your specific needs.
Cryptocurrencies like Bitcoin and Ethereum are native to their blockchains. Tokens are built on top of existing blockchains using smart contracts. Tokens can represent various assets: fungible tokens (like stablecoins), non-fungible tokens (NFTs), or governance tokens.
DeFi refers to financial services built on blockchain without traditional intermediaries. This includes lending protocols, decentralized exchanges (DEXs), derivatives, and yield farming. Users maintain control of their assets and earn returns through smart contract interactions.
Start with our Blockchain 101 guide to understand fundamental concepts. Then explore smart contract basics. Progress to practical tutorials and hands-on development. Our structured learning paths guide you from beginner to advanced developer.
This depends on your background and learning pace. Basic blockchain concepts can be understood in weeks. Becoming proficient in smart contract development typically requires 2-3 months of dedicated study and practice. Mastery takes longer and continuous learning.
