Blockchain

PHP developer jobs in the Blockchain space involve building applications that interact with decentralized ledger technologies. While PHP is not typically used to build core blockchain protocols, it is a popular choice for developing the web applications, APIs, and back-end services that connect to them.

PHP's Role in the Web3 Ecosystem

In a blockchain role, a PHP developer might build a web interface for a decentralized application (dApp), create a REST API to query blockchain data, or develop services that interact with smart contracts on platforms like Ethereum. These positions require a strong foundation in back-end development combined with a solid understanding of blockchain principles.

Essential Skills and Knowledge

• Strong proficiency in PHP and a modern framework like Laravel or Symfony.
• Understanding of core blockchain concepts such as wallets, transactions, smart contracts, and decentralization.
• Experience using libraries like web3.php to interact with Ethereum nodes via JSON-RPC.
• A security-first mindset is critical when handling cryptographic keys and transactions.
