TBC (Turing Bit Chain)

Absolute Security and PoW Mechanism: Faithfulness and Evolution
Satoshi Nakamoto's thoughts on blockchain security run throughout; he emphasized in forums:
"The system design aims to protect user privacy, but not absolutely. Every transaction is broadcast on the network."
"The utility of transactions achieved by Bitcoin will far surpass the cost of electricity consumption. Therefore, not having Bitcoin is the real waste."
These statements reveal Satoshi Nakamoto's profound insight into the balance of "security - utility": privacy is a relative goal, while network transparency and the cost investment of PoW consensus ultimately serve the core value of "trustless transactions." TBC transforms this philosophy into technical practice:
By inheriting Bitcoin's PoW consensus mechanism, sharing the computational power of its 1.3 million mining machines as a shield, and building a distributed network of 16,000 full nodes, the success rate of long-range attacks is reduced to the order of 10⁻¹⁸;
At the same time, dynamic data pruning technology reduces storage costs for light nodes in 4GB ultra-large blocks, ensuring transaction broadcast transparency while avoiding potential regulatory obstacles posed by "absolute privacy."
TBC proves that the energy consumption of PoW is not wasteful but a necessary security premium paid for the great experiment of "peer-to-peer electronic cash"—as Satoshi Nakamoto said, without this investment, "not having Bitcoin is the real waste."
II. Ultra-Low Transaction Friction: Balancing Technological Breakthroughs and Inclusive Payments
Satoshi Nakamoto was always cautious in technical design about "over-defense" eroding practicality; he proposed, "We must set sufficiently high thresholds to prevent spam transactions, but low enough to allow legitimate use."
The 1MB block size limit of Bitcoin's mainnet was essentially a temporary compromise to resist dust attacks in the early days, but it led to transaction fees peaking near $50, diverging from the original intention of "inclusive payments." TBC achieves Satoshi's "balance philosophy" through two core technologies:
First, increasing the initial block capacity to 4GB, allowing each block to contain 900 high-definition video data streams, fundamentally eliminating congestion;
Second, reconstructing block header logic using a layered hash verification algorithm, expanding capacity while maintaining verification efficiency at the level of 1MB blocks, avoiding the complexity of Ethereum's sharding scheme.
Ultimately, TBC locks transaction costs at $0.0002 per transaction, filtering spam transactions through a dynamic fee model, and restoring vitality to legitimate scenarios such as micro-payments and cross-border remittances with "cent-level costs," truly fulfilling Satoshi Nakamoto's original design intent of "allowing legitimate use."
