$TBC TBC uses the UTXO model, just like Bitcoin, which means that each transaction is clear, traceable, and secure. Value is not maintained in accounts but transferred through individual outputs, making validation simple and reducing risk. This maintains the network's decentralization and resistance to attacks while preserving Bitcoin's original design. Unlike TBC, UTXO is no longer a limitation. TBC has upgraded it to support smart contracts and parallel execution, making transactions faster and more efficient. This makes UTXO an advantage—providing scalability, low fees, and real-world usability without sacrificing security.
