The rollout of native P2P networking reduces manual peer configuration and simplifies relay setup, improving resilience and reducing operational friction. Source: IOG blog on Cardano P2P networking. For trading workflows, operating your own node provides direct submission through the node-to-client interface and independent confirmation of block inclusion, mitigating reliance on external RPC endpoints during high-load market conditions.
