A lightweight client, also known as a light client, is a software application that interacts with a blockchain network without needing to download and store the entire transaction history. Instead, it relies on cryptographic proofs, such as Merkle proofs, to verify the validity of transactions and block headers from full nodes. This approach significantly reduces the computational and storage requirements for users. It enables participation with minimal resource consumption.
Context
Discussions about lightweight clients are common in news related to blockchain scalability, mobile accessibility, and wider adoption of decentralized applications. Their ability to provide secure, yet resource-efficient, access to blockchain data is critical for expanding the reach of digital assets to a broader user base. Ongoing developments aim to enhance the security and functionality of lightweight clients, addressing concerns about trust assumptions and potential vulnerabilities.
