Comprehensive guides

We are writing this today because the SWQoS mechanism is shifting into a dynamic, congestion-aware system as part of the upcoming Agave 4.0 release, with Agave 4.1 bringing even bigger changes to how the protocol handles ingress.

TL;DR * Solana uses Proof of History (PoH) as a shared, cryptographically verifiable clock to *pre-order* events before consensus. PoH itself is not the full consensus mechanism. Solana uses PoH alongside a Proof-of-Stake BFT consensus (called Tower BFT) to agree

Learn how Solana streaming works, what its key characteristics are, when to use it instead of RPC polling, and how to work with the Yellowstone gRPC stack.

Institutions and protocols often face a choice between visibility and operational overhead. This guide explains how the validator-as-a-service model works and the due diligence required to protect your stake and reputation.

The wrong infrastructure choice can lead to failed transfers and stale data. This guide provides a checklist of essential features and reliability standards to help you vet RPC providers for your production workload.

Understanding how applications communicate with the blockchain is the first step to building on Solana. We break down the fundamental concepts, connection types, and architecture so you can start on solid ground.

Choosing the wrong infrastructure can lead to performance bottlenecks and hidden costs. Learn how to evaluate provider reliability, performance, features, and support standards so you can build a stable foundation for enterprise scale.

Classically, we define these terms as follows: latency is the time it takes for data to reach its destination. Bandwidth is the maximum number of bits that can pass through a given path of wire at the same time.
