What Is the Primary Security Assumption for an SPV Client?
The primary security assumption is that the majority of the network's full nodes are honest and will not collude to present a false block header with a tampered Merkle Root. An SPV client trusts the block header it receives from a full node, relying on the difficulty of the PoW to secure that header's integrity against fraudulent inclusion of a transaction.
