EntrapNet: a Blockchain-Based Verification Protocol for Trustless Computing
This addresses security and efficiency issues in trustless computing for IoT applications, representing an incremental improvement by applying blockchain and optimization techniques to an existing domain.
The paper tackles the problem of verifying computing results from trustless service providers in distributed shared computing networks, proposing EntrapNet, a blockchain-based protocol that mathematically optimizes the tradeoff between security and efficiency with an asymptotic optimal solution.
In this paper, we propose a blockchain-based computing verification protocol, called EntrapNet, for distributed shared computing networks, an emerging underlying network for many internet of things (IoT) applications. EntrapNet borrows the idea from the practice of entrapment in criminal law to reduce the possibility of receiving incorrect computing results from trustless service providers who have offered the computing resources. Furthermore, we mathematically optimize EntrapNet to deal with the fundamental tradeoff of a network: security and efficiency. We present an asymptotic optimal solution to this optimization. It will be seen that EntrapNet can be performed as an independent and low-cost layer atop any trustless network that requires outsourced computing, thus making secure computing affordable and practical.
