Part 5/7:
The dialogue also explored the dynamics of whether individual wallets could function as nodes. The explanation clarified that, while each user operates through a lightweight client (also known as an SPV), they need only receive header hashes — thereby reducing the complexity of interactions with the blockchain.
What’s more, by keeping essential data from previous transactions, individuals can use “Merkle proofs” to validate the legitimacy of transactions without scanning the entire blockchain. This systematic approach reduces the burden on participants and preserves the core functionality of the network.
