If your trading system is losing to faster data, the fix is usually infrastructure, not code. I'm Oussama Allamou (0xMowgli). I set up and run dedicated Solana nodes on bare metal that serve Geyser gRPC and shred streams to latency-sensitive clients. I deliver the node, the streaming layer, the monitoring, and a multi-region layout that switches on latency. This is for trading teams, bot operators and anyone who wants to stop depending on a shared endpoint.
/ 01 · Scope
Solana nodes on bare metal, provisioned and tuned for your workload. No shared tenants, and no rate limits you did not set.
Account, transaction and slot updates pushed over gRPC as the node processes them, filtered so clients receive only what they need.
Shreds are the fragments of a block that propagate before the block is complete. For systems that need the earliest signal available.
Nodes in more than one region, with clients moved to the fastest healthy endpoint.
Prometheus and Grafana on slot lag, stream delay and hardware health, with alerts that fire before clients notice.
Nginx in front, with authentication and per-client limits, whether the consumers are your own services or paying subscribers.
/ 02 · Process
Which programs and accounts the system watches, and how much delay it can tolerate. That decides everything below.
Once the specs are adequate, location relative to the rest of the network and to your own servers matters more than extra cores.
Operating system, disks, network, node configuration and the Geyser plugin.
The same events, timed on both paths, on your own traffic. You see the difference as numbers.
Client upgrades, restarts, full disks, a region going bad. Someone has to own these, and it is agreed up front who.
/ 03 · Proof
I also run a Solana gRPC and shred-stream provider on dedicated nodes. It is private work, so regions, hardware and subscribers are not published. Details are shared on a call.
/ 04 · FAQ
Not always. If your product reads balances and sends ordinary transactions, a paid RPC plan is cheaper and less work. You need dedicated nodes when you compete on timing, when you stream enough data to hit provider limits, or when you want to sell access yourself. I would rather tell you that you do not need one than build one you will not use.
RPC is request and response: you ask the node a question. WebSocket subscriptions push updates, with more overhead and less control. Geyser gRPC streams updates from the validator's plugin interface as it processes them. Shreds come earlier still: they are the pieces of a block as the leader broadcasts it, before your node has replayed it. Each step is faster and harder to consume.
I can't give a number before measuring, and nobody honest can. It depends on where you are today, where the hardware sits and what you subscribe to. What I can do is time the same events on both paths and show you the difference before you commit to a long hardware contract.
Hardware is the main cost. A Solana node needs a high core-count CPU, a lot of RAM, fast NVMe storage and serious bandwidth, so it is rented as a dedicated server by the month. A second region roughly doubles the bill. I size it against the workload so you pay for what the system uses.
Bare metal for the nodes. Solana is heavy on disk and network, and virtual instances on shared storage tend to fall behind the chain or cost far more for the same performance. Supporting services such as APIs, databases and dashboards can live wherever is convenient.
