What is BNB?

BNB, originally known as Binance Coin, is a cryptocurrency developed by Binance, one of the largest cryptocurrency exchanges in the world. Initially created in July 2017 on the Ethereum blockchain as an ERC-20 token, BNB has since moved to its own blockchain, the BNB Chain, which was formerly known as the Binance Smart Chain. The move to a proprietary blockchain was primarily to handle the large transaction volumes that Binance experiences and to create a more scalable network.

How Does the BNB Chain Work?

The BNB Chain operates using a consensus model known as Proof of Staked Authority (PoSA). It combines elements of Proof of Stake and Delegated Proof of Stake (DPoS), where participants stake BNB to become validators. If they are chosen to validate transactions, they earn transaction fees as rewards. This system not only enhances transaction speeds but also significantly lowers the cost, making it a competitive blockchain for deploying and operating decentralized applications (dApps).

On the BNB Chain, blocks are validated every three seconds, which is incredibly fast compared to older blockchains like Bitcoin or Ethereum. This speed makes the BNB Chain an attractive option for developers looking to build high-performance dApps. Additionally, the BNB Chain supports compatibility with Ethereum’s tools and dApps, allowing developers to migrate their projects without starting from scratch.

What is BNB Used for?

BNB has multiple uses within the Binance ecosystem and beyond, making it a multi-functional asset. Here are some of its primary uses:

Trading Fee Discounts: One of the initial purposes of BNB was to offer a discount on trading fees for users on the Binance platform. Users who hold BNB in their accounts and use it to pay for trading fees enjoy significant discounts, incentivizing traders to purchase and hold the coin.
Participation in Token Sales: BNB is used on Binance’s Launchpad platform, where new and emerging tokens are launched. Holding BNB enables users to participate in these token sales, often at a lower entry price than what is offered to the public post-launch.
Ecosystem Utility: Beyond trading, BNB is increasingly used to power transactions across Binance’s growing network of Decentralized Finance (DeFi) services, entertainment, online services, and financial applications. For example, BNB can be used to pay for goods and services, settle transaction fees on Binance’s decentralized exchange, participate in exclusive token sales, and even book travel accommodations on websites that accept it.
Governance: As the BNB Chain has evolved, BNB also plays a role in the governance of its blockchain operations. Holders can vote on various upgrade proposals and decisions that impact the development and operation of the ecosystem.
Staking: Users can stake their BNB to support network security and operations and in return, receive rewards. Staking involves locking up tokens to earn the right to participate in the network operations, and it rewards participants with additional BNB over time, based on the amount they stake.

The versatility of BNB extends its utility beyond mere cryptocurrency trading. For example, in 2019, Binance partnered with several technology and travel firms that began accepting BNB as a form of payment, greatly expanding its real-world application. As the BNB ecosystem continues to grow, its uses and applications are likely to increase, potentially making it a staple in the broader digital economy.
