SPV Proof
Simplified Payment Verification (SPV) is a method that allows a user to verify if a transaction was included in a block without downloading the entire blockchain. It relies on the Merkle proof to demonstrate that a specific transaction exists within the block represented by the Merkle Root in the block header.
The client requests the necessary hash path from a full node and performs the validation locally. If the path leads to the expected Merkle Root, the transaction is considered verified.
This is the core mechanism that enables lightweight wallets to function securely. It minimizes the data footprint while maintaining cryptographic assurance.
