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

How do I set up a custom RPC for Optimism?

Accepted Answer

Setting up a custom RPC for Optimism means configuring your wallet or dApp to use a specific endpoint instead of the default public one. This guide covers the chain settings you need, how to add Optimism to MetaMask, and how to choose a reliable RPC provider for production use.

Question 4

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 5

ZKsync Uptime: What to Monitor and How to Keep Your dApp Resilient

Accepted Answer

ZKsync uptime refers to the availability of the ZKsync network and its RPC endpoints. While the network's official status page tracks sequencer and API health, your dApp's reliability also depends on your RPC provider's redundancy and failover strategy. This article explains what to monitor, how to evaluate providers, and how to build resilience into your stack.

Question 6

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 7

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 8

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 9

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 10

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 11

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 12

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.
