  "map_content": "Core Responsibilities of Full Nodes\r\nCore Responsibilities: Whether for BTC or BSV, the core duties of a full node are to download and store blockchain data, independently verify whether transactions and blocks comply with consensus rules, and reject invalid blocks without trusting any third party. Fulfilling these three points grants permissionless verification rights.\r\nBTC Full Node Philosophy\r\nPhilosophy Overview: Verification for everyone. It aims to lower the barrier to running a full node, enabling ordinary users to independently verify the Bitcoin network.\r\nBlock Design: The block size is permanently maintained at 1\u20134MB. Full nodes have low requirements for disk space, bandwidth and computing power, keeping the cost of synchronizing complete historical data manageable. The total blockchain size from 2009 to 2026 is approximately 700GB, operable on regular personal computers with residential broadband.\r\nDesign Purpose: To increase the number and geographic distribution of full nodes and maximize the decentralization of verification rights. It prioritizes allowing anyone to independently verify network rules from home, with security derived from the highly decentralized nature of verification authority.\r\nBSV Full Node Philosophy\r\nPhilosophy Overview: Verification undertaken by professional nodes. It prioritizes massive transaction throughput rather than making full node operation accessible to everyone. Its primary goal is to ensure the network can support real-world scale adoption.\r\nBlock Design: The protocol-level block size cap is removed, allowing blocks to scale alongside hardware, bandwidth and market demand. It is the world\u2019s only public blockchain capable of processing GB and TB-scale data on-chain, with a 4GB block already mined in 2023.\r\nDesign Outcome: Single-chain transaction throughput is boosted, and the unit cost of on-chain transactions and data is reduced. However, hardware, bandwidth and operation maintenance requirements for running a full node rise significantly. Full nodes are operated by professional miners and enterprise-grade data centers, competing in the market for block production and validation. The goal is to maximize on-chain processing capacity and the scale of economic activity, with security underpinned by genuine, sustained on-chain economic activity and transaction fee incentives.\r\nValue of BTC Full Nodes\r\nImpact on Network Power Structure: Ordinary users running full nodes cannot participate in block bookkeeping or rule-making, and thus do not alter the network\u2019s power structure. With low propagation efficiency, full nodes mostly serve to safeguard personal verification rights at the individual level.\r\nPersonal Privacy Protection: Running a full node avoids privacy leaks associated with light nodes (SPV nodes), restoring users\u2019 financial privacy.\r\nBSV Full Node Characteristics & Privacy Mechanism\r\nNode Characteristics: Large block sizes raise the barrier to node operation while lowering the per-transaction cost, making the network suitable for high-frequency, micro-payment and data-intensive applications. The total number of nodes decreases, with higher reliance on miner competition, network bandwidth and infrastructure. Network security is tied to on-chain economic activity.\r\nPrivacy Handling: Anonymity is not solved at the protocol layer; privacy matters are delegated to the application and network layers. Ordinary user wallets can complete queries and transactions via relay servers. The underlying protocol remains simple, transparent and auditable, while upper-layer applications implement privacy protection flexibly.\r\nComparative Summary\r\nTrust Establishment: BTC builds trust through mathematics and universal public verification; BSV builds trust via professional nodes, legal frameworks and commercial systems.\r\nRole Positioning: Ordinary users act as verifiers in the BTC ecosystem, while they function as regular users in the BSV ecosystem.\r\nPrivacy Approach: BTC embeds privacy into the base protocol, whereas BSV leaves privacy implementation to applications and legal regulation. The core divergence lies in their respective models of trust in the real world.",
