TBC (Turing Bit Chain)
Based on this architecture, DeFi applications on TBC exhibit security features that are fundamentally different from traditional ecosystems. Taking decentralized exchanges as an example: users do not need to authorize the platform to operate their wallet assets during transactions; instead, they complete "money for goods" directly through the atomic swap feature of UTXO. Even if there are vulnerabilities in the platform's contracts, hackers cannot steal assets that users have not actively signed transactions for. The same applies to lending protocols—assets pledged by users are always under their control and are only automatically executed through pre-signed transactions when liquidation conditions are met, rather than transferring the operational rights of the assets to the contract in advance. Even NFT transactions achieve true "payment upon delivery": as the buyer pays, the ownership of the NFT is transferred through a single UTXO, and neither party needs to trust a platform intermediary. The commonality of these scenarios is that security no longer relies on "trust" in third parties, but rather achieves "trustless" inherent security through architectural design.
What is even more noteworthy is that TBC's UTXO model is driving a "paradigm shift in security." The traditional DeFi security approach is based on "bug fixing" and "audit reliance"—project teams need to continually patch contract vulnerabilities, and users must always be vigilant about authorization risks. In contrast, TBC's approach is "architecture immunity"—eliminating the need for authorization at the base level, thereby making most attack vectors fundamentally nonexistent. For example:
No phishing attack risk: Since there is no approve transaction, hackers cannot forge authorization pages to deceive permissions;
No contract vulnerability theft: Even if the contract written by the developer has oversights, hackers cannot directly transfer user assets;
No unlimited authorization abuse: Users cannot set "unlimited limits" at all, and all transactions must be explicitly signed.
This transformation not only reduces users' security anxiety but also frees developers' creativity—they no longer need to spend a lot of effort designing complex permission management logic, but can instead focus on product experience and innovation.
