BNB Chain

• is comprised of 3 components

  • BNB Beacon Chain - responsible for governance voting & staking

  • BNB Smart Chain (BSC) - EVM compatible blockchain for transactions

  • ZkBNB - built on ZK Rollup architecture with much lower gas fee

  • BNB App Sidechain (BAS) - dedicated chain for particular projects/services

ZkBNB

• ZK (Zero Knowledge) Rollup architecture is a layer 2 solution for scaling

• funds are still hold in BSC, ZkBNB only handles computations & storage of state change

• batch of transaction computations are roll-up in ZkBNB's Rollup Block then generate a proof called SNARK

• higher throughput with lower gas fees, but still share same security as BSC does

BNB Chain Application Sidechain (BAS)

• increase network's scalability & speed of finality

• compatible to Binance smart chain Dapps

• independently used for specific application/service

• dedicated validators for the sidechain based on security needs

• be able to customise gas token to create utility of the token

• cross-chain interoperability by 3rd party bridge lock & mint mechanism

BNB Greenfield

• decentralised storage infrastructure

• EVM-compatible smart contract native integration on BSC via cross-chain mechanism

• anonymous cryptographic-based keys (IDs) for login, provides full ownership of create, store & exchange data

• provide a high-performance data service with sharding on the buckets

Data Storage Flow

• users upload data and configure unique access & usage permissions

• BNB Greenfield stores data off-chain with proper redundancy and backup

• metadata of users’ BNB ledger is stored on the BNB Greenfield blockchain

• data stored in the BNB Greenfield ecosystem can easily be transferred to BSC

• can be used as website hosting, cloud storage, social media platform with full ownership

BNB Burn system

• burning means permanently removing token from circulation to reduce the total supply

• BNB burns include users spent it as gas fee & quarterly BNB burning

• reduce its total supply by 50% until it’s under 100 million BNB in the long term

• create deflationary effect & potentially increases BNB’s valuation

• burn lesser to compensate BNB holders who accidentally sent token to ‘black hole’ address
