Question 1

What Is the SORA Project and How Does the SORA Blockchain Work?

Accepted Answer

The SORA project is a blockchain initiative focused on decentralized finance and monetary systems, evolving from a Polkadot parachain into SORA Nexus, a Hyperledger Iroha 3-based network. This article explains the SORA blockchain's architecture, its transition to SORA v3, and how developers can connect to it via RPC endpoints.

Question 2

How to Mine TAO on Bittensor: A Practical Guide for Developers

Accepted Answer

Mining TAO on Bittensor means running a miner on a subnet that produces a digital commodity—such as inference, compute, or storage—and getting rewarded in TAO. This guide explains the roles of miners, validators, and subnets, how to choose a subnet, and the practical steps to register and run a miner, including the RPC endpoints you'll need to interact with the Finney network.

Question 3

Optimism API: What It Is and How to Use It for OP Mainnet

Accepted Answer

The Optimism API is the set of JSON-RPC endpoints that let applications read and write data on OP Mainnet, an Ethereum Layer 2 built with optimistic rollups. It follows the same JSON-RPC standard as Ethereum, so you can use familiar libraries like ethers or viem to interact with the chain. This article explains what the Optimism API is, how it differs from Ethereum's API, and how to choose the right endpoint provider for your project.

Question 4

What is a BNB node and when should you run one?

Accepted Answer

A BNB node is a client that stores the BNB Smart Chain state and processes transactions. Running one gives you direct access to the chain, but it requires significant hardware and maintenance. For most applications, a managed RPC service like OnFinality provides a more practical way to interact with BNB Chain without the operational overhead.

Question 5

What Is the SORA Blockchain Project and How Do You Build on It?

Accepted Answer

The SORA blockchain project is a decentralized monetary system and DeFi platform built on Substrate, designed to create a supranational economic framework. It includes the XOR token, the Polkaswap DEX, and the TBC (Token Bonding Curve). This article explains the project's architecture, how to connect to the SORA network via RPC endpoints, and how to choose the right infrastructure for building applications.

Question 6

What is blockchain node infrastructure and when should you rent it instead of running it?

Accepted Answer

Blockchain node infrastructure is the hardware, software, and networking that keeps a blockchain network running. It includes full nodes, archive nodes, and validators, each with different storage and compute needs. Running your own nodes gives you control, but it also brings operational overhead like syncing, monitoring, and scaling. Managed RPC services like OnFinality provide reliable access to node infrastructure without the burden of self-hosting.

Question 7

PublicNode Rate Limits: What to Expect and How to Plan Around Them

Accepted Answer

PublicNode offers free RPC endpoints for many chains, but like most public services it applies rate limits to protect shared infrastructure. This article explains how those limits typically work, how to detect them, and when to move to a dedicated or commercial RPC provider for production workloads.

Question 8

What Is dOrg and How Does It Work?

Accepted Answer

dOrg is a decentralized autonomous organization (DAO) that operates as a collective of senior Web3 developers and builders. It delivers blockchain and AI development services to protocols, DeFi projects, and institutions, functioning as a team extension or milestone-based contractor rather than a traditional agency.

For developers evaluating dOrg, understanding its structure, engagement models, and how it compares to hiring in-house or using other service providers is key. This article breaks down what dOrg is, how it operates, and what to consider before engaging with it.

Question 9

Sui gRPC Providers: Public, Managed & Dedicated RPC Compared

Accepted Answer

Sui gRPC providers give applications a typed, streaming path to Sui data, but access models differ significantly. Public Foundation gRPC endpoints can suit prototypes and low-volume tooling; evaluate their current limits, support, and production terms before depending on them. Managed gRPC providers operate shared endpoints with documented capacity, monitoring, and support, making them a practical default for dApps, indexers, and backend workers. Dedicated Sui gRPC nodes isolate your workload on private infrastructure and are justified when burst behavior, latency, or compliance requirements outgrow shared capacity. The evaluation should be gRPC-first: confirm LedgerService and StateService read support, TransactionExecutionService for ExecuteTransaction and SimulateTransaction, and SubscriptionService for SubscribeCheckpoints, SubscribeTransactions, and SubscribeEvents. Also verify rate limits, burst allowances, regions, failover, and incident communication before moving production traffic. OnFinality provides managed Sui gRPC and RPC infrastructure for mainnet and testnet, with a path to dedicated nodes when workloads need isolation. Start from /networks/sui to review current Sui network support.

Question 10

What Is Mangata X and How Do You Connect to Its RPC?

Accepted Answer

Mangata X is a community-owned, omnichain decentralized exchange (DEX) built as a Substrate-based app-chain on Kusama, designed to minimize MEV and enable cross-chain swaps. This page explains what Mangata X is, how to connect to its RPC endpoints, and how to evaluate infrastructure options for building on it.

Question 11

What is a TON testnet RPC and how do you use it?

Accepted Answer

A TON testnet RPC endpoint lets you interact with the TON testnet, a sandbox environment for building and testing dApps, wallets, and smart contracts without risking real TON. This article explains the available endpoints, how to authenticate, and how to choose a reliable provider for your development workflow.

Question 12

Dedicated Solana RPC Nodes: Shared vs Private Infrastructure

Accepted Answer

A dedicated Solana RPC node is a single-tenant Solana RPC endpoint reserved for your application or team. It runs the same Solana client software as a shared node, but with isolated CPU, memory, storage, and network capacity. Shared RPC—whether a public endpoint or a managed multi-tenant service—is usually faster to adopt and cheaper to operate, but it can be affected by other users' traffic and rate limits. Dedicated infrastructure gives you predictable capacity, custom node configuration, and stronger isolation for latency-sensitive or high-volume workloads. It also costs more and adds operational responsibility unless you use a managed service. Choose shared first for prototypes, staging, and moderate production traffic. Move to dedicated when you see sustained rate limiting, need consistent latency for trading or real-time indexing, require custom streaming or node configuration, or want architectural separation between critical and non-critical workloads. Use the checklist and comparison table in this guide to evaluate costs, capacity, and workload fit before committing.
