Question 1

Bittensor Mining Tutorial: How Do You Keep a Miner Registered and Online?

Accepted Answer

Bittensor mining is not hash-rate mining. Miners run a model or service inside a subnet, register a hotkey on the Subtensor chain, and earn emissions when their responses are scored well by validators. This tutorial walks through the practical path: pick a subnet, set up wallets, register, run the miner, and keep the chain connection stable.

The most common failure point is not the model, it is connectivity. Registration, weight setting, and metagraph sync all depend on reliable Subtensor RPC access. This page shows how to configure the Bittensor Finney endpoint, test it, and decide when a dedicated node or managed RPC endpoint is the better operational choice.

Question 2

What Is a TON Public Node and When Should You Use One?

Accepted Answer

A TON public node is a shared RPC endpoint that lets you read TON blockchain data and submit transactions without running your own node. It is the fastest way to get a wallet, script, or prototype talking to TON, but shared endpoints come with rate limits, variable latency, and no operational guarantees.

This article explains how TON RPC differs from EVM chains, how to connect to a public endpoint, when a public node is enough, and when to move to a managed RPC API or a dedicated node for production workloads.

Question 3

Free Solana API: What You Actually Get and When to Move On

Accepted Answer

A free Solana API gives you an HTTP and WebSocket endpoint that speaks Solana's JSON-RPC methods, so you can read accounts, send transactions, and subscribe to logs without running a validator. The catch is that free tiers are shared, rate-limited, and often not suited to production traffic or heavy archive queries.

This article explains what a free Solana API can realistically handle, how to test it with real JSON-RPC calls, and the signals that tell you it is time to move to a paid shared plan or a dedicated Solana node from OnFinality.

Question 4

When did peaq mainnet launch, and what does it mean for your 2025 build?

Accepted Answer

peaq's mainnet went live in 2024, moving the DePIN-focused Layer 1 from testnet experiments to a production network where machines, vehicles, and IoT devices can register identities and settle value on-chain. If you are building on peaq now, the launch date matters less than the operational question it raises: which RPC endpoint and node setup will keep your DePIN app responsive as device traffic grows.

This page covers the launch timeline, the Agung testnet relationship, the chain settings you need to connect, and how to decide between a public RPC endpoint and dedicated node infrastructure for production workloads.

Question 5

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 6

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 7

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 8

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 9

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 10

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.

Question 11

Bittensor Miner Setup: From Wallet to Registered UID

Accepted Answer

Setting up a Bittensor miner means preparing a coldkey/hotkey wallet, funding it with TAO, registering a UID on a subnet, and then running the subnet's miner process against a reliable Finney RPC endpoint. The RPC layer matters because registration, stake checks, and metagraph sync all depend on consistent chain access.

This guide walks through the practical setup path, the decisions that trip people up (subnet choice, registration cost, endpoint reliability), and how to keep a miner running once it is registered. It also covers when a shared public endpoint is enough and when a dedicated node or managed RPC endpoint is the better fit.

Question 12

Ajuna RPC Endpoint: Chain Settings, Connection Options, and Debugging

Accepted Answer

Ajuna is a Polkadot-based network designed for gaming and on-chain application workloads. This page covers what developers need to connect to it: the chain settings, how to point a wallet or client at an Ajuna RPC endpoint, and how to debug common connection failures.

If you are moving from a public endpoint to something more reliable for production, OnFinality provides RPC API access and dedicated node infrastructure for supported networks. Check the Ajuna network page and RPC pricing to confirm current availability before you migrate.
