Simple Payment Verification (SPV) clients download only a small subset of the blockchain.
This allows low resource devices, such as mobile phones, embedded devices, or tablets, to be able to verify the transactions.
Verifying Transactions Without Downloading the Full Blockchain
A complete Ethereum blockchain and node are not required in this case, and SPV clients can still validate the execution of transactions.
There is a wallet available from Jaxx (https://jaxx.io/), which can be installed on iOS and Android, which provides the SPV functionality.
Why This Matters for Blockchain Technology
Understanding Light clients is not just an academic exercise — it has real-world implications for how blockchain systems are designed, deployed, and secured. Whether you are a developer building decentralized applications, a business leader evaluating blockchain adoption, or a curious learner exploring the technology, this knowledge provides a critical foundation.
