According to @ItsDave_ADA, spinning up a Cardano relay node to submit and verify transactions without relying on centralized infrastructure is straightforward, underscoring the network’s self-sovereign design for traders.

Cardano’s cardano-node and cardano-cli enable permissionless relay operation, local transaction submission, and independent verification of on-chain state.

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.

According to Paolo Ardoino, Holepunch has made 267 public repositories available, containing essential modules for cryptography, P2P networking, data structures, algorithms, and consensus mechanisms. This move towards open source provides valuable resources for developers and could influence the crypto ecosystem significantly.
