Question 1

How do I choose a Celo RPC provider for a production app?

Accepted Answer

Celo is an EVM-compatible network with a mobile-first history and a growing set of stablecoin and payment use cases. For most teams, the practical question is not whether to use an RPC provider, but which provider fits your read/write mix, archive needs, and failover plan. This article walks through the Celo chain settings, the workloads that stress an endpoint, and the criteria that separate a shared public endpoint from a dedicated node deployment.

You will find a quick decision section, a provider evaluation matrix, request examples against the Celo mainnet endpoint, and a debugging path for the failure modes that show up most often in Celo integrations.

Question 2

How to Mine Solana: Why You Can't, and What to Do Instead

Accepted Answer

Solana does not use proof-of-work mining, so there is no way to mine SOL with GPUs or ASICs. The network runs on a proof-of-stake plus proof-of-history model where validators stake SOL, produce blocks, and earn rewards and fees. If your goal is to earn SOL, the realistic paths are staking, running a validator, or building on Solana. If your goal is to build or operate on Solana, the practical work is connecting to reliable RPC infrastructure rather than mining hardware. This article explains the mechanism, the alternatives, and how to connect to Solana mainnet and devnet endpoints for real workloads.

Question 3

Bittensor TAO Mining in 2025: Subnet Economics, Node Setup, and RPC Requirements

Accepted Answer

Bittensor mining in 2025 is no longer a single-network activity. Miners and validators compete inside individual subnets, each with its own incentive mechanism, model type, and registration cost, so the practical question is which subnet you can serve profitably and what infrastructure that subnet demands. This article walks through the decisions that matter: choosing a subnet, sizing hardware, registering a hotkey and coldkey, and connecting your miner process to the chain reliably.

Beyond the mining logic itself, every miner and validator depends on a stable connection to the Bittensor Finney mainnet for registration, weight setting, and stake operations. We cover the RPC and node infrastructure layer, including when a public endpoint is enough and when a dedicated node or managed RPC service such as OnFinality makes more sense for a production miner.

Question 4

Bittensor Subnet 123: What Is It and How Do You Connect?

Accepted Answer

Bittensor Subnet 123 is one of the numbered incentive-based subnets that run on top of the Bittensor network. Each subnet has its own task, miner and validator incentive design, and its own on-chain registration and stake accounting, so "Subnet 123" is best understood as a specific subnet's netuid rather than a fixed product name. If you are building on it, the practical question is usually how to read its state and how to reach the Bittensor chain reliably.

This page explains what a Bittensor subnet netuid means, how to inspect Subnet 123 through the chain, and how to connect using a Bittensor RPC endpoint. OnFinality provides RPC API access and dedicated node options for Bittensor Finney, so you can query subnet data without running your own node.

Question 5

What Hardware Does a Bittensor Mining Rig Actually Need?

Accepted Answer

A Bittensor mining rig is not a GPU box that hashes blocks. It is a machine that runs a miner process registered to a subnet, where the real work is model inference or training and the reward comes from your rank against other miners. The hardware decision depends on which subnet you target, not on a single global spec sheet.

This article breaks the rig into its parts, explains how CPU, GPU, VRAM, storage, and network each affect your ability to compete, and shows where a managed RPC endpoint fits so your rig spends its resources on compute instead of chain sync.

Question 6

Polygon RPCs: How to Pick an Endpoint That Survives Production Traffic

Accepted Answer

Polygon RPCs are the HTTP and WebSocket endpoints your app uses to read chain state, submit transactions, and subscribe to events on Polygon PoS. The endpoint you pick early tends to become the endpoint you debug at 2am, so it is worth choosing against your real workload rather than a quick copy-paste from a tutorial.

This page walks through the endpoint shape, chain settings, request patterns, and the failure modes that show up once traffic grows. It also explains when a shared public endpoint is enough and when a managed RPC API or dedicated node from OnFinality is the better fit.

Question 7

Which Solana RPC Methods Do You Actually Need in Production?

Accepted Answer

Solana exposes a JSON-RPC interface with a broad set of methods for reading accounts, submitting transactions, and subscribing to live updates. The methods you enable depend on your workload: wallets need blockhash and sendTransaction, indexers need getProgramAccounts and getSignaturesForAddress, and trading systems lean on WebSocket subscriptions and priority fee estimation. This reference maps common Solana RPC methods to real use cases, shows request examples, and explains the limits that shape production architecture. It also covers how to pick an endpoint, when shared public RPC is enough, and when a dedicated Solana node from OnFinality makes more sense for sustained or high-volume traffic.

Question 8

What Should You Evaluate in a Solana Node Provider?

Accepted Answer

A Solana node provider gives your application an RPC endpoint (and sometimes WebSocket access) to the Solana cluster, so you don't have to run and maintain validator or RPC infrastructure yourself. The right provider depends on your workload: read-heavy dApps, high-frequency trading bots, indexers, and analytics pipelines each stress different parts of the node.

This article breaks down how to evaluate Solana node providers, what to test before committing, and where OnFinality's Solana RPC API and dedicated nodes fit into a production stack.

Question 9

What is a Solana light node and when should you use one?

Accepted Answer

A Solana light node is a client that keeps only the state it needs to verify accounts and transactions, rather than storing the full ledger. It is useful for wallets, dashboards, and edge services that need fast reads without running validator-grade hardware. For most production apps, a managed RPC endpoint or a dedicated node replaces the operational burden of running a light client yourself. This article explains what a light node does on Solana, how it differs from validators and full nodes, and how to decide between self-hosting and using RPC infrastructure.

Question 10

RPC Service and Dedicated Node Access for Solana Projects: What Should You Compare?

Accepted Answer

Solana projects hit different bottlenecks than EVM apps: high request volume, WebSocket subscriptions, and heavy getProgramAccounts-style reads can overwhelm shared public endpoints. This article explains how to evaluate RPC services and dedicated node access for Solana, including what to test before you commit, how to configure endpoints, and where dedicated infrastructure fits. OnFinality offers Solana RPC API access and dedicated node options, and you can review supported networks and pricing to match your workload.

Question 11

What RPC provider selection criteria matter most for a Solana dApp?

Accepted Answer

Solana dApps put unusual pressure on RPC infrastructure: high request volume, frequent account and program reads, WebSocket subscriptions, and bursts around transactions and market events. Provider selection should be driven by workload shape, not by a single headline number. The criteria that matter most are method coverage, WebSocket and subscription support, archive and historical data access, rate-limit and burst behaviour, failover design, and how transparently the provider handles Solana-specific failure modes such as stale slot reads and dropped subscriptions.

This article gives you a practical evaluation matrix for Solana dApp RPC, a quick way to test an endpoint before you commit, and a checklist for moving from a shared public endpoint to a managed RPC API or dedicated node when your traffic grows. OnFinality provides Solana RPC API access and dedicated node options, and you can review coverage on the supported networks and RPC pricing pages before choosing a plan.

Question 12

What should I know about the peaq network?

Accepted Answer

peaq is a Layer-1 blockchain purpose-built for Decentralized Physical Infrastructure Networks (DePIN) and machine economies. It provides the settlement layer, identity primitives, and token incentives that let connected devices, robots, and sensors transact autonomously. Developers interact with peaq through its Substrate-based RPC interface, which exposes standard JSON-RPC methods for reading chain state, submitting extrinsics, and subscribing to events.

If you are building on peaq, the practical question is how to get reliable RPC access without running your own validator or archive node. OnFinality provides managed RPC API and dedicated node infrastructure for peaq, so teams can connect wallets, indexers, and backend services to the network without operating the underlying hardware. This article covers peaq's architecture, how to connect, what to watch for in production, and when a managed provider makes sense.
