2.3.2 L2 Layer 2 Network
L2 (Layer 2 Network) is a solution to scale blockchain performance and throughput. In the L2 solution, opBOB (Optimistic BOBchain Virtual Machine) is one of its core components.
opBOB aims to improve the performance of BOBchain Virtual Machines (BOBs) through optimistic execution. It is based on the PoVC arithmetic value consensus mechanism, which allows nodes (BOINC AI servers) to contribute arithmetic power through smart contracts for task assignment at the root node. Compared with the traditional consensus method of "solving complex mathematical problems", this method can greatly improve the processing speed and throughput of transactions, while avoiding the waste of arithmetic power and energy.
The role of opBOB is to execute the model-trained transactions on the L2 Layer 2 network and submit the results to the L1 main chain. By moving the transactions from the main chain to the second tier network, opBOB reduces the burden on the main chain, improves overall performance, and reduces the cost and latency of the transactions.
