 But from that baseline of EVM compatible, BNB Smart Chain introduces  a system of 21 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.

 - **Distributed with on-chain governance**: Proof of Staked Authority brings in decentralization and community participants. As the native token, BNB will serve as both the gas of smart contract execution and tokens for staking.

-# 1.Background
-This is to support some projects with customized tokens that they want to integrate into the BSC faucet tool.
-
-## 1.1. How to Integrate Your Token
-- Step 1: Fund the faucet address by sending a specific amount of your BEP-20 token to the faucet address (0xaa25aa7a19f9c426e07dee59b12f944f4d9f1dd3) on the BSC testnet.
-- Step 2: Update this README.md file and create a Pull Request on [bsc github](https://github.com/bnb-chain/bsc) with relevant information.
-
-We will review the request, and once it is approved, the faucet tool will start to support the customized token and list it on https://www.bnbchain.org/en/testnet-faucet.
