Draft:Build n Build chain

Build N Build Chain, is a blockchain ecosystem designed to enable decentralized applications and services through various interconnected layers. Launched in 2020, it comprises several components that work together to platform for developers, users, and creators. According to their webpage, the BNB Chain ecosystem is built on the principles of decentralization, open access, and community-driven development.

BNB token
The BNB token, short for "Build and Build," is the native cryptocurrency of the BNB Chain ecosystem. It serves multiple functions, including acting as a transactional currency similar to gas on Ethereum. Holding BNB tokens provides users with the ability to participate in the decentralized governance of BNB Chain.

Binance Coin was established in 2017, and the Binance Smart Chain was introduced three years later during the DeFi. The BNB token has continuously evolved since its debut. Initially, created as an ERC-20 token on the Ethereum network in 2017, and was an Ethereum fork, it quickly switched over to the then Binance Chain and fueled the establishment of the early Binance Smart Chain network, which was officially launched in September 2020.

Binance Smart Chain later merged with the older Binance Chain and was rebranded into BNB chain. BNB Chain operates using "Proof of Staked Authority", a combination of proof of stake and proof of authority. As of 2023, Binance Coin was the cryptocurrency with the fourth highest market capitalization.

BNB underwent a transformation to embrace decentralization on its chain, granting substantial decision-making power to BNB holders through voting mechanisms. This shift emphasizes the community's active involvement and influence over the platform's evolution.

Components
BNB Beacon Chain: Launched April 2019, the BNB Beacon Chain serves as the staking and governance layer of the BNB ecosystem. It allows participants to stake their tokens for rewards and actively participate in the decentralized decision-making process that shapes the future of the BNB Chain.

BNB Smart Chain (BSC): BSC is an Ethereum Virtual Machine(EVM)-compatible blockchain within the BNB ecosystem. It facilitates the creation of decentralized applications and smart contracts, bringing programmability and interoperability to the network.

zkBNB: zkBNB is an infrastructure built on the zk-Rollup architecture. It caters to developers by providing them with tools to create large-scale applications on the BSC platform, focusing on higher throughput and significantly reduced or zero transaction fees.

opBNB: The opBNB network functions as a Layer 2 scaling solution for BSC, leveraging the Optimism opStack technology. It aimed to enhance the efficiency and scalability of the BNB Smart Chain, contributing to improved user experience. The testnet was released in Q2 2023.

BNB Greenfield: BNB Greenfield introduces a novel paradigm for data in the era of Web3. It aimed to empower users and participants within the BNB Chain ecosystem to take ownership of data, its usage, and monetization.

Historical milestones
2020: The launch of BNB Smart Chain marked the beginning of BNB Chain's journey, attracting a community of developers, users, and enthusiasts. Notable projects like PancakeSwap and Venus contributed to its growth.

2021: The Most Valuable Builder (MVB) program sought to encourage collaboration and innovation within the ecosystem.

2022: The AvengerDao Security Initiative enhanced security, privacy, and scalability. BNB Chain also launched zkBNB in the same year.

2023: BNB Chain introduced BNB Greenfield and opBNB, via testnet launches. The Zero2Hero Incubator and Kickstart Program were also key events in that year to encourage innovation. Daily active users surpassed 1.2 million for BNB Chain.

Builder Grant Program
The Builder Grant program, initiated in 2022, provides funding and access to BNB ecosystem developers, enabling grantees to contribute essential resources to enhance the long-term utility of BNB Chain. Eligible projects encompass open-source frameworks, free developer tooling, compatibility modules, and other developer infrastructure projects. With BNB Chain's commitment to free and open-source projects, this program empowers developers to make a significant impact and enrich the ecosystem.

Gas Grants
This initiative rewards projects that contribute to the BNB Chain ecosystem by providing gas fee incentives to qualified participants. With a dedicated pool of USD 200,000 worth of BNB tokens each month, this program supports decentralized applications to scale with the aid of reduced gas fees.

Kickstart Program
This program provides essential tools and services grouped into a starter pack called BNB Chain Kickstart, targeted at developers' needs.

DappBay
The platform provides features such as discoverability and rankings, in-depth analytics, featured listings, risk assessment, security features, and authentic reviews and ratings.
