How Does an SPV Wallet Trust the Block Headers It Receives?
An SPV wallet trusts the block headers it receives by connecting to multiple full nodes and checking for consistency. It assumes that a majority of the full nodes it connects to are honest and will provide the correct longest chain of block headers.
By observing the difficulty of the chain and ensuring the Merkle Root is present in the header, the SPV wallet gains probabilistic trust. It does not perform the full verification of every transaction, but rather relies on the network's consensus mechanism to secure the header's integrity.
Glossar
SPV
Architecture ⎊ Special Purpose Vehicles, within cryptocurrency, function as segregated entities designed to isolate risk and facilitate specific financial operations, often involving the issuance or management of tokenized assets.
Block Headers
Information ⎊ Block Headers are the succinct summaries of a block's content and validation parameters, acting as the primary mechanism for chain linkage and Proof-of-Work verification across the peer-to-peer network.
Spv Wallet Trust
Trust ⎊ In the context of Spv (Simplified Payment Verification) wallets, trust represents a nuanced interplay between cryptographic assurance and operational reliance.
