Blockchain Smart Contract for Task Verification - Enhanced with Oracles

To incorporate external data or conditions into the verification process, smart contracts can interact with oracles:

$$V'(T_j, N_i, O_k) = \begin{cases}  1 & \text{if } T_j \text{ by node } N_i \text{ is verified by oracle } O_k \\ 0 & \text{otherwise} \end{cases}$$

Where $O_k$ represents an oracle providing external data or verification services.

These enhanced equations and algorithmic explanations aim to provide a more comprehensive and technically profound insight into the operational mechanics of Blendr's decentralized GPU computing network, ensuring a robust and forward-thinking platform design.
