Acting as an infrastructure provider, collaborating with Validator and L2-Edge to provide high quality storage, bandwidth and compute services to customers. 2. Monitoring and evaluating the quality of service of all L2-Edge nodes as per Validator's scheduling and reporting the results to Validator. **Online Hours:** Must remain online throughout the day **Node Configuration Requirements** To ensure high performance and stability of the network, L1 nodes must meet the following configuration requirements: * **Processor:** 16 Virtual Cores (vCPUs) * **Memory:** 16GB * **Storage:** 10TB * In the current testnet, the expected usage is around 20% (1 to 2TB) * N**etwork bandwidth:** 500 Mbps downstream, 200 Mbps upstream, fixed public IP (IDC)
