The introduction of Simplified Payment Verification (SPV) in the Bitcoin white paper is significant because it allows lightweight clients to verify transactions without needing to download the full blockchain. This innovation enables users with limited resources, such as mobile devices or computers with less storage, to still utilize the Bitcoin network securely. By leveraging Merkle trees, SPV allows these clients to obtain proof of transactions' inclusion in a block without requiring access to the entire blockchain, which enhances accessibility and usability of Bitcoin.

This feature is particularly crucial for the growth of the Bitcoin ecosystem, as it facilitates wider adoption, enabling more people to engage with Bitcoin transactions without needing extensive technical knowledge or significant computing power. In contrast, the other concepts mentioned—Proof of Stake, Smart Contracts, and Decentralized Governance—were not part of Bitcoin's original protocol as outlined in Satoshi Nakamoto's white paper but emerged in later discussions and developments in the broader cryptocurrency space.
