BNB Beacon Chain Documentation

Welcome to the BNB Beacon Chain documentation site!

Please note that both the BNB Beacon Chain software and this documentation site will improve over time and is still a work-in-progress.
Be sure to engage with our community channels to stay updated.

Have fun trading and see you on chain!

What are BNB Beacon Chain and Binance DEX?​

BNB Beacon Chain is a blockchain software system developed by its community. Binance DEX refers to the decentralized exchange features developed on top of BNB Beacon Chain.

Please read the FAQ to get started.

What is BNB Smart Chain?​

BNB Smart Chain is an innovative solution to bring programmability and interoperability to BNB Beacon Chain . BNB Smart Chain relies on a system of 41 validators with Proof of Staked Authority (PoSA) consensus that can support short block time and lower fees. The most bonded validator candidates of staking will become validators and produce blocks. The double-sign detection and other slashing logic guarantee security, stability, and chain finality.

Please read the FAQ to get started.

What can I do with BNB Beacon Chain ?​

The purpose of the new blockchain and DEX is to create an alternative marketplace for issuing and exchanging digital assets in a decentralized manner.

You can:

For traders, you can:

For developers, you can also:

  • Explore the transaction history and blocks on the chain, via BNB Beacon Chain Explore, API and node RPC interfaces.
  • Run a full node to listen to and broadcast live updates on transactions, blocks, and consensus activities
  • Extract other data of BNB Beacon Chain via full node or APIs
  • Develop tools and application to help users use BNB Beacon Chain and Binance DEX

What can I do with BNB Smart Chain ?​

BNB Smart Chain (BSC) is best described as a blockchain that runs in parallel to the BNB Beacon Chain . Unlike BNB Beacon Chain , BSC boasts smart contract functionality and compatibility with the Ethereum Virtual Machine (EVM). The design goal here was to leave the high throughput of BNB Beacon Chain intact while introducing smart contracts into its ecosystem.

Because BSC is EVM-compatible, it launched with support for the rich universe of Ethereum tools and DApps. In theory, this makes it easy for developers to port their projects over from Ethereum. For users, it means that applications like MetaMask can be easily configured to work with BSC. Seriously – it’s just a matter of tweaking a couple of settings. Check out Use MetaMask for BNB Smart Chain to get started.

You can:

  • Send and receive BNB and other BEP2 tokens cross-chain
  • Explore the transaction history and blocks on the chain, via bscscan, API and node RPC interfaces.
  • Stake you BNB to earn some block rewards

Developers can also:

  • Issue new tokens to digitalize assets
  • Migrate existing DApps
  • Run a full node to listen to and broadcast live updates on transactions, blocks, and consensus activities
  • Develop wallets and tools to help users use Dapps

Asset Management​

BEP2 Asset​

BNB Beacon Chain is essentially a digital asset creation and exchange platform.
The features listed below are currently supported on BNB Beacon Chain :

BEP20 Asset​

A token protocol on BSC which is compatible with BEP2 and ERC20. It extends ERC20 and contains more interfaces, such as getOwner and decimals. Read the full proposal here: https://github.com/bnb-chain/BEPs/blob/master/BEPs/BEP20.md

BNB (and Other Coins) MainNet Switch​

Build N Build Coin (BNB) was an ERC20 token on the Ethereum network. After the launch of BNB Beacon Chain, Build N Build Coin (BNB) is being converted into native BNB tokens on the main network via the exchange platform at binance.com, a pragmatic and efficient way to perform the initial token swap.

BNB Beacon Chain is ready for other projects to migrate their tokens to take advantage of performant transactions with more liquidity options and native marketplace features.
More information about how projects can set themselves up for this (via binance.com or partners) will come soon.

BNB Staking​

Trading on Binance DEX​

Binance DEX is the native marketplace on BNB Beacon Chain , allowing you to exchange digital assets issued and listed on it.
The matching happens within the blockchain nodes and all of the transactions are recorded on-chain, therefore forming a complete, auditable ledger of activity.

ATTENTION: The match logic on DEX is quite different from normal centralized exchange.
Please go over the trading and match spec below to get the best interests for your orders.
