What is a BSC Node?

A BSC node is a fundamental component within the BNB Smart Chain (BSC) network. Furthermore, BSC nodes play a crucial role at the core of this programmable blockchain network. After all, they are the components that help maintain the network’s integrity and functionality.

Essentially, a BSC node is a software application, and by running on a server or local computer, this software participates in the BSC network. Its job is to validate transactions, process smart contracts, and store a copy of the BSC blockchain ledger. Each node plays a vital role; however, the true power lies in nodes working together. After all, this network of BSC nodes joins forces to collectively ensure the security, transparency, and decentralization of the BSC network.

What is BSC and BNB Smart Chain?

BSC now stands for BNB Smart Chain. However, before February 2022, BSC stood for Binance Smart Chain. In either case, the abbreviation points to the same chain. It’s just a question of semantics!

As you may know, the Binance blockchain (officially called Binance Chain) launched back in April 2019. At the time, the chain had the purpose of hosting the BNB token and facilitating fast decentralized trading. The BNB token was initially born on Ethereum back in 2017 and transitioned to Binance Chain in 2019. And it wasn’t until September 2020 that the Binance organization/community launched its own programmable blockchain, capable of hosting smart contracts. That is the chain that devs use to create tokens and dapps. At the time of launch, this programmable network was called Binance Smart Chain. 

However, in February 2022, the Binance Foundation decided to rename/rebrand their two chains. This rebranding created an umbrella name – BNB Chain – for both the governance/trading chains and the programmable chain. 

The 2022 “Build and Build” rebranding also renamed Binance Chain into BNB Beacon Chain and Binance Smart Chain into BNB Smart Chain. It also changed the chain’s native token name from Binance Coin to “Build and Build” (BNB). However, BNB was the token’s initial symbol/ticker anyway.

This quick summary should help you clarify things for good:

  • The network that serves governance and trading/staking purposes: BNB Beacon Chain (formerly Binance Chain). 
  • The network that serves as a programmable blockchain (EVM-compatible, consensus layer): BNB Smart Chain (BSC) (formerly Binance Smart Chain).
  • BNB Beacon Chain + BNB Smart Chain (BSC) = BNB Chain.

How Does a BSC Node Work?

A Binance Smart Chain (BSC) node works as a crucial component of the BSC network by participating in various processes to maintain the blockchain’s functionality and integrity: 

  • Blockchain Data Storage: A BSC node stores a complete copy of the BSC blockchain ledger. This ledger contains records of all transactions, smart contracts, and account balances that have occurred on the network. The node continually updates this ledger as new transactions come in, ensuring it has the most up-to-date information.
  • Transaction Validation: Whenever users initiate transactions on the BSC network, they get broadcasted to multiple nodes. BSC nodes verify the validity of the transaction by checking various factors. For example, the nodes check if the transaction sender has sufficient funds and whether the transaction adheres to the network’s rules and consensus mechanisms.
  • Consensus Participation: BSC uses a proof-of-stake (PoS) consensus mechanism. So, BSC nodes, specifically validator nodes, participate in this consensus process. They propose and confirm new blocks of transactions. To run a validator node, users need to stake BNB as collateral. The network chooses validators for transactions based on their BNB stake and reputation.
  • Smart Contract Execution: BSC nodes have the capability to execute smart contracts. When a smart contract is invoked, nodes process the contract’s code and execute the predefined actions encoded within it. 
  • Network Communication: BSC nodes communicate with each other to propagate transactions, share blocks, and reach consensus.
  • API Services: BSC nodes offer APIs that allow developers and decentralized applications (dapps) to interact with the blockchain programmatically. 
  • Block Production: Validator nodes take turns producing new blocks (batches of confirmed transactions) in the BSC blockchain. 
  • Decentralization: By running multiple nodes across different geographic locations and operated by various entities, BSC nodes contribute to the decentralization of the network. 
How to Run a BSC Node?

How to Run a BSC Node

When it comes to running a BSC node, you have several options. One approach requires you to download the latest version of the blockchain and run the required software. In certain situations, taking this path makes sense. However, for the majority of developers who just want to create dapps or launch tokens on top of the BSC network, there’s a much simpler path.  

Binance Website with information on how to set up a BNB Smart Chain Node

You can learn more about each of the two methods of running a BSC node in the following subsections. 

Running a BSC RPC Node the Hard Way

In case you plan on taking on a project that requires you to run a full BSC node, make sure to visit the above-outlined documentation page. This is where you’ll learn all you need to know about the hardware and software prerequisites. On that site, you’ll also find out about the amount of BNB tokens you need to execute that mission.

Furthermore, the BNB Chain documentation also highlights the following steps required to run a BCS node:

  1. Setting Up the Environment
  2. Compiling the Code
  3. Configuring the Node
  4. Initializing the Blockchain
  5. Running the Node
  6. Becoming a Validator (Optional)
  7. Monitoring and Maintenance
  8. Security Measures
  9. Community Engagement
  10. Backup and Recovery

Before embarking upon the above steps, it’s important to note that running a BSC node is a significant commitment. It requires technical expertise and resources to set it up and to run it smoothly. As such, unless your project demands you to run your own node, you should either focus on using BSC RPC node providers or simply use the Moralis API.  

Running a BSC RPC Node the Easy Way

If you decide to deploy your smart contracts, you will need access to a BCS node. However, this doesn’t mean you need to take the difficult approach outlined in the above section. Instead, you can use a reliable BSC RPC node provider. 

There are many providers out there, and it can be quite challenging to sift through all the options. As such, we created a curated list of reliable node providers. This list allows you to run a BSC RPC node the easy way and enables you to do so for other reputable chains.
