What is BNB? A Beginner's Guide

Key Points

• Binance Coin (BNB) was founded in 2017 by tech entrepreneur Changpen Zhao (AKA CZ).
• BNB is the native utility token of the Binance exchange, the largest cryptocurrency exchange in the world.
• Binance’s multiple chains and platforms use a unique combination of Proof of Stake (PoS) and Proof of Authority (PoA) consensus mechanisms to validate network transactions. The combination of both models leads to comparatively lower fees and faster transaction speeds.

• The BNB Beacon Chain migrated to the BNB Smart Chain (BSC) in December 2024. The BSC aims to improve efficiency, reduce security risks and align BNB Chain’s architecture with the current demands of blockchain technology, while focusing on future growth.

Is it a utility token? Is it a discount token? Is it a governance token?

No, it's BNB, and it's everything rolled into one.

Native token to one of the largest crypto exchanges in the world, BNB powers a now established ecosystem of decentralised apps (dApps), decentralised finance (DeFi) and Binance exchange users.

As of early 2026, the BNB Chain ecosystem facilitates over 12 million daily transactions, with high-volume days seeing over 17 million transactions. Offering high-speed, low-cost operations, the network often exceeds US$9 billion in daily trading volume. For reference, daily transaction volume on the Ethereum network currently stands at 1.7 million.

In this guide, we outline what BNB is, its use cases and how to buy BNB in 2026.

What is Binance & the BNB Chain?

Since its inception in 2017, Binance has become one of the largest brands in the crypto industry. Aside from being the largest crypto exchange, it has launched an entire ecosystem of crypto-related functionalities. BNB is an integral component of this ecosystem.

In the weeks before the launch of Binance, the company offered BNB to early investors via an initial coin offering (ICO). The coin was priced at about $0.11 per unit during its ICO. At the time of writing, BNB trades around US$595 and has a market cap of US$80.9 billion.

Outside of operating as an exchange, Binance runs multiple blockchains within its interconnected ecosystem. The architecture consists of the following blockchains:

• BNB Beacon Chain (retired in December 2024): handled governance across the network, which included staking and voting on proposed changes to the network. The BNB Beacon Chain was previously known as Binance Chain.
• BNB Smart Chain (BSC): handles smart contract creation and execution. Previously known as Binance Smart Chain, this chain took on the responsibilities of the outgoing BNB Beacon Chain from December 2024 when the final sunset fork was completed.
• opBNB: is a layer-2 solution built on the BNB Chain that aims to achieve faster transaction speeds and lower fees for users in the BNB ecosystem.
• zkBNB: is also a layer-2 scaling solution for the BNB Chain, but it uses zero-knowledge proofs and enables faster transactions and lower fees, particularly for gaming and social applications.

BNB Greenfield: is a decentralised storage solution within the BNB Chain ecosystem, allowing users to control their data and build applications with a focus on data ownership and a new data economy.

BNB trades on the BSC and opBNB as a utility token and regularly sits in the top 5 crypto assets by market cap. The coin’s Build’N’Build abbreviation is a motto that reflects the network’s gradual move towards a collaborative, participatory, open-source project, which has remained following the migration from the BNB Beacon Chain to BSC in late 2024.

How is the BNB Chain Different from Ethereum?

Ethereum and the BNB Chain do share some functional similarities. Below the surface though, the networks couldn’t be any more different.

Ethereum started as a not-for-profit, decentralised, open-source project that sought to build upon concepts established by Bitcoin. While Binance (the organisation) started as a for-profit, centralised, private company attempting to create the largest crypto exchange ever. While both organisations share the same drive to innovate, their motivations probably differ.

The BNB Chain and Ethereum also use different consensus mechanisms. Ethereum uses Proof of Stake since The Merge in September 2022. The BNB Chain uses a hybrid Proof of Stake Authority (PoSA) to validate network transactions.

The ethos behind the BNB Chain is different. Through implementing a PoSA consensus model, network creators have actively chosen to sacrifice decentralisation in favour of scalability potential. This is the fundamental difference between the BNB Chain and Ethereum.

Previously, when compared to Ether (ETH) in terms of utility, BNB use cases dwindled as users favoured the Ethereum sphere to gain exposure to a much wider variety of dApps. While Ethereum still leads the way here, Binance’s (BSC) dApp environment has since flourished. As of early 2026, it’s estimated that TVL on the BSC is worth US$6 billion.

How Does The BNB Chain Work?

Proof of Stake Authority

The main BNB Chains combine elements from a PoS model with PoA to uphold the network.

• Users need to stake at least 10,000 BNB for a chance to be selected as a validator.
• Users without this amount can delegate their stake to an elected validator, receiving a portion of any rewards the validator receives.
• Outside of staking 10,000 BNB, validators also stake their own reputation, operating in public as opposed to anonymously.
• While operating publicly is not an uncommon practice among mining companies on other blockchains, is it a requirement on the BNB Chain, not a choice.

PoSA on the BNB Chain uses significantly fewer validators than networks such as Bitcoin or Ethereum. By giving up decentralisation at this stage of the validation process, the network hopes to weed out bad actors from becoming validators. By centralising control amongst a few validators, the network is also able to accompany a relatively higher transaction volume across fewer validators.

Smart Contracts

In 2020, Binance launched the BNB Smart Chain, offering smart contract functionality to the BNB Chain. Using a set of predetermined conditions, smart contracts allow two separate parties to conduct and carry out agreements without relying on an intermediary.

The use of smart contracts on the BNB Smart Chain has helped the network gain more utility while reducing the overall cost to create and implement contracts between two parties. Over 2,000 dApps and 1-million plus users trust in this technology daily.

Some developers have flocked to the BNB Smart Chain because smart contracts are comparatively cheaper to create on the network. Some argue these fees are low because traffic on the BNB Smart Chain is lower (when compared to Ethereum). Either way, the gas fee difference is significant. At the time of writing, BNB Chain gas fees are typically around US$0.001 to US$0.005, compared to Ethereum’s US$0.01. However, Ethereum's Layer-2 rollups go some way to addressing this issue, with gas fees on Arbitrum and Optimism priced less than a cent.

The graphic below provides an example of how smart contracts work.

Decentralised Apps (dApps)

Smart contracts also have paved the way for the creation and use of DApps. Like smartphone or computer applications, dApps have a wide range of functionalities. Rather than running on a central server, the code of a DApp is committed via a smart contract to the blockchain. The BNB Chain’s peer-to-peer network can then execute the app’s smart contract without the need for a centralised authority.

Non-fungible tokens (NFTs)

The network has also added functionality for creating, collecting, and selling non-fungible tokens (NFTs). As Binance NFTs are very new, time will tell whether their popularity exceeds the likes of an earlier blockchain like Ethereum.

Tokenisation

BNB Chain also functions as a foundational layer (known as a Layer 1) for other crypto projects. The native tokens for these projects are known as BEP-2 tokens, but they’ll soon be BSC-standard because of the migration. Think of BEP-2 as a set of standardised instructions all assets created on the blockchain must follow. This standard works to ensure that anything created on the BNB Chain can seamlessly interact with any other tokens within the ecosystem.

What is BNB?

BNB is the native token on the BNB Beacon Chain. It can be used to pay for goods and services within and outside of the network. BNB is also used to pay gas fees on the BNB Smart Chain.

Outside of this, BNB has a range of useful functions on the BNB Chain. These include:

• Trading fee discounts when you pay in BNB on Binance’s exchange
• Access to exclusive token sales
• Access to the BNB Chain ecosystem of DeFi gaming, DApps, and more

BNB uses an auto-burn mechanism to continuously reduce its total supply to 100,000,000 BNB. This mechanism helps the network manage ongoing supply and demand pressures.

Advantages & Disadvantages of BNB

Binance, as the world’s most well-known exchange, has helped BNB grow in popularity. But an exchange and a blockchain are two different things. Success in one of these areas doesn’t indicate perfection in the other. Let’s explore what advantages BNB Chain brings to potential investors, along with some disadvantages that it could improve upon.

Advantages

• Low Fees: Because of the unique PoSA consensus mechanism, the BNB Chain processes more transactions with less validator participation and computational energy. As a result, fees are quite low when compared to other smart contract blockchains like Ethereum.
• Great For Binance Users: If you already use the Binance exchange, having BNB on hand is comparable to having airline reward points. You can use BNB to reduce fees on every trade, for payment on various supported platforms, and to gain access to exclusive NFT drops.
• Unique Burning Mechanism: BNB’s auto-burn feature works to ensure that the coin can deal with the ongoing pressures of supply and demand. Auto-burning will continue until 100 million BNB remain in the market.
• Programmability: Although in its early stages, the use of smart contracts means that the BNB Smart Chain is highly programmable. Any app or protocol built on the network can interact with one another. If the network’s community continues to grow, we may see innovative use cases arise from this programmability.
• Tokenisation: Any item that can be registered in a digital format can be tokenised on the BNB Chain. While tokenisation is commonly used in the NFT space, it has real-world applications in real estate, art, and even gold. Think of it as a digital certificate of ownership for an asset.

Disadvantages

• Centralised: The Binance chains are attached to a private company, Binance. It also uses the PoSA consensus model. In this model, transaction verification is concentrated in the hands of a small group of validators who can afford to participate in the process. These validators also need to give up information that could be used to identify them. When compared to other networks, the BNB Chain leans more towards centralisation, which flies in the face of some of the foundational ideas of crypto. This set-up also creates a very centralised point of failure since attackers only need to target a few key nodes to compromise the system.
• Target for Cyber Attacks: While the BNB Chain itself is safeguarded by cryptographic blockchain technology, Binance the exchange has frequently been targeted by hackers seeking to penetrate hot wallets. This could be a concern for security-conscious investors. In 2022, a Binance bridge’s vulnerability saw $570million stolen.

Who Created BNB?

Changpeng Zhao, a veteran of traditional Wall Street finance and cryptocurrency, launched Binance in 2017. Changpeng is famously known as CZ in the crypto community.

CZ started from humble beginnings. Having immigrated from China to Canada at age 10, he often worked various hospitality jobs to support his family during his teenage years. He later majored in computer science at McGill University.

Afterwards, CZ landed an internship on the Tokyo Stock Exchange, developing software to match trade orders. He then acquired a full-time position as a developer at Bloomberg, creating software for futures trading.

He is the founder and CEO of BijieTech, a company that supplies exchange operators with cloud-based exchange solutions. CZ was previously the co-founder and CTO of OKCoin and the co-founder of Fusion Systems.

Around 2013 he became more involved in crypto and worked for various crypto projects (like Blockchain.info). Four years later, CZ launched Binance. He used the funds generated from BNB’s ICO to further build out the exchange.

CZ has since resigned from Binance after pleading guilty to money laundering charges. He completed a four-month prison sentence in September 2024, and was pardoned by President Trump in October 2025, ending the legal consequences of his earlier guilty plea. Zhao personally paid a US$50 million fine, while Binance paid a US$4.3 billion fine.

A Brief History of BNB

How to buy BNB in 2026

Buying BNB

There are three primary ways to obtain BNB - buying, earning, or staking. Staking is considerably expensive as a validator, but investors can alternatively delegate their stake to an existing validator. Buying BNB outright is considerably easier than staking.

The easiest way to buy BNB is through a brokerage like Caleb & Brown. If you’re ready to dive in and make your first BNB purchase, Caleb & Brown is here to help.

How to Store BNB

There are multiple ways of storing BNB, from a cold wallet, hot wallet or with a custodian. Individual risk tolerance and preferences will determine the method employed by most users.

Cold wallets are completely disconnected from the internet. As such, they cannot be easily hacked and are often seen as a safer option for infrequent traders. These storage devices often resemble USB flash drives. Cold wallets have additional built-in layers of security to prevent a data breach once you connect it to the internet for trading.

Hot wallets are connected directly to the internet, usually through a phone or desktop application. Their popularity lies in their ease of use and ability to make trades quickly.

Many of these storage methods can seem complex, especially if you are not tech-savvy. Caleb & Brown provides end-to-end custody solutions for hassle-free storage and peace of mind investing.
