BNB HODLer Issue 60 In-Depth Analysis: Why Not All Computations Should Be On-Chain?

Many developers today fall into a misconception — believing that smart contracts must handle everything. In reality, historical data scanning, complex strategy calculations, cross-chain state judgments, and even AI model inference often result in two outcomes when forced on-chain: either gas fees skyrocket to unbearable levels, or the system becomes dependent on centralized oracle intermediaries, actually increasing systemic risk.

Is there a better solution? Off-chain execution + on-chain verification architecture is changing this reality. By moving computation-intensive tasks off-chain for execution and only verifying result credibility on the blockchain, we reduce costs while maintaining decentralized security guarantees. This approach breaks through traditional constraints in contract design, opening new possibilities for DeFi, cross-chain bridges, on-chain AI applications, and beyond.
