Node Architecture

Full Node vs Archive Node

The difference is not academic. It changes your storage bill, your sync time and the queries your product can answer.

RPC Performance

Understanding RPC Infrastructure

RPC is the front door of every onchain product. Here is what sits behind a production endpoint.

RPC Performance

Dedicated RPC vs Shared RPC

Shared endpoints are cheap until your product depends on them. An objective look at the trade off.

Baremetal

Cloud vs Baremetal for Blockchain Workloads

Blockchain nodes are continuous, IO heavy and bandwidth hungry. That profile changes the usual cloud calculus.

Baremetal

Why Blockchain Workloads Need High Performance Storage

State growth, random reads and constant writes. Storage is the component that quietly decides node performance.

Blockchain Security

Securing Blockchain Infrastructure

The attack surface of a node fleet has little to do with smart contracts and everything to do with infrastructure security.

Infrastructure Security Beyond Smart Contracts

Contract audits cover code. They do not cover the machines, identities and pipelines running it.

Kubernetes for Blockchain Infrastructure

Where orchestration helps a node fleet, where it adds risk, and a split that works in production.
