A peer-to-peer (P2P) network of nodes is employed to verify transactions, ensuring they have not been double-spent. This verification process is essential for maintaining the integrity of a decentralised cash system where users can directly interconnect to exchange value. Simplified Payment Verification (SPV) enables users to validate the digital signatures of the messages they receive without accessing a full node to confirm the correctness of the signed message. Users need only consult a node to verify whether a transaction has been double-spent, allowing them to confirm the authenticity and integrity of their transactions while minimising computational and storage requirements.
The concept of distributed networks, as introduced by Baran (1964), provides the foundational structure for such a system. Distributed networks allow for multiple robust points of failure, ensuring that no single point of failure can disrupt the network. This resilience makes the network robust and reliable. Baran's work highlighted that such a network structure ensures continuity and security even under adverse conditions, forming a bedrock for modern digital transaction systems.
In Section 5 of the Bitcoin White Paper, Nakamoto (2008) outlines that nodes in the network are responsible for validating transactions and ensuring no double-spending occurs. Double-spending is a potential flaw where the same digital currency can be spent more than once. Nodes collect transactions into blocks and verify them against the blockchain, which acts as a public ledger of all transactions. Nakamoto (2008) states, "Nodes validate transactions, add them to their block, and broadcast the block to the network."
SPV allows users to verify transactions without operating a full node. SPV nodes download only the block headers instead of the entire blockchain, enabling users to confirm their transactions with fewer computational and storage resources. Users can ensure their transactions have been included in a block and validated by the network without participating in the full transaction validation process. Nakamoto (2008) explains, "A user can verify payments without running a full network node."
Direct IP-to-IP connectivity allows users to transact directly with each other. Users hold the cryptographic keys to their funds. When a transaction is made, it is broadcast to the P2P network. Nodes then validate and add it to the blockchain, preventing double-spending. Users can rely on the P2P network for transaction validation without needing to run their own nodes, ensuring the network’s integrity and security. Nakamoto (2008) discusses, "The network itself can support a large number of transactions and is expected to grow to handle transaction volumes comparable to major credit card networks like Visa." This statement underscores Bitcoin’s potential to scale and become a major player in global financial transactions.
Nakamoto envisioned Bitcoin handling transaction volumes comparable to major financial networks like Visa. In a discussion, Nakamoto (2010) stated, "Visa processed 37 billion transactions in FY2008, or an average of 100 million transactions per day. Bitcoin can already scale much larger than that with existing hardware for a fraction of the cost." This highlights Bitcoin’s scalability and its potential to revolutionise the financial industry by providing a cost-effective and efficient transaction network.
