UTXO's Technological Breakthrough: From Transaction Certificates to Machine Economy Infrastructure
Compared to traditional account models, the fundamental difference of UTXO (Unspent Transaction Output) lies in its redefinition of "value"—it does not record "who has how much," but rather "which values have not yet been spent." This design philosophy allows UTXO to demonstrate three major technological advantages in machine economy scenarios that are unmatched by traditional models:
1. Revolutionary Breakthrough in Parallel Computing: From Serial to Concurrent Value Flow
Traditional account models use a "balance locking" mechanism, where multiple transactions for the same account must be processed serially (e.g., when A transfers 100 yuan to B, A's balance must be locked first, then the next transaction can proceed). This mechanism completely fails in machine economy scenarios—when 100,000 devices initiate payment requests simultaneously, serial processing will cause the transaction queue to backlog infinitely.
UTXO achieves true parallel verification through a discrete "transaction input - output" structure: each transaction depends only on specific UTXO inputs, and as long as UTXO inputs do not overlap between different transactions, they can enter the verification queue simultaneously. Based on this, TBC public chain further optimizes by using Dynamic Hash Lock technology, increasing UTXO's parallel processing capacity to over 13,000+ TPS (transactions per second).
2. Breaking Through the Limits of Micro-Payment Infrastructure: From "Payable" to "Unlimited Payments"
Traditional payment networks' fee models (such as proportional fees or fixed fees) inherently exclude micro-payments—when a single transaction's value is lower than the fee, the transaction becomes economically meaningless. UTXO solves this problem thoroughly through a calculation method where "transaction fee = total input × rate" (often simplified in practice to base fee + byte fee).
Building on this, the TBC public chain introduces "Large Block Infinite Expansion" technology: with its 4GB ultra-large block design, the cost of a single transaction is compressed below $0.0002. This "ultra-low cost + ultra-high concurrency" combination enables each smart streetlight sensor (which generates 20 micro-payments per day) to reduce annual transaction costs to $0.15, completely removing cost barriers in machine economy.
3. Native Support for Data Trustworthy Carrier: From "Value Transfer" to "Value + Data Fusion"
Traditional blockchain's "value" and "data" are separated—value flows through UTXO, while data is transmitted via sidechains or Oracles, and trust relationships between the two require additional verification. UTXO's scripting system (Script) naturally supports binding data with value: by encoding sensor data as script conditions (e.g., "Unlock payment when temperature ≥ 30℃"), it enables an atomic operation of "data as condition, payment as verification."
This "data - payment" binding mechanism not only raises the cost of data tampering to astronomical levels (requiring control of over 51% of the computing power), but also allows machine collaboration without relying on third-party data verification, truly realizing an autonomous economy where "code is law."
