What is B3?

Question

What is B3?

Accepted Answer

## TLDR
B3 (Base) is a hyper-scalable Layer 3 blockchain ecosystem built on Coinbase's Base network, designed primarily to bring fun, consumer-scale applications—especially games—onchain with ultra-low cost and high performance.

1. **A Gaming & Consumer L3** – It's a dedicated blockchain for games and apps, settling on Base to offer sub-cent fees and fast transactions.
2. **Powered by the $B3 Token** – The native ERC-20 token enables ecosystem governance and commerce, such as purchasing in-game items.
3. **An Expanding Superchain** – Its architecture allows developers to easily launch interoperable appchains, forming a connected network of experiences.

## Deep Dive
### 1. Purpose & Value Proposition
B3 aims to make fully onchain gaming and consumer applications commercially viable by solving scalability and cost issues. It provides dedicated blockspace as a Layer 3 (L3) settling on Base, which itself is a Layer 2 on Ethereum. This design slashes transaction fees to a fraction of a cent and enables lightning-fast speeds, targeting the performance needed for web2-scale games ([B3 Docs](https://docs.b3.fun/points-sdk)).

### 2. Technology & Architecture
B3 is an Ethereum Virtual Machine (EVM)-compatible L3. Its "Open Gaming" network allows game-specific chains (GameChains) to settle onto B3, with infrastructure that abstracts away multi-chain complexity for developers and users. Key innovations include horizontal scaling via sharding and a composable architecture for seamless cross-chain asset interoperability ([B3 MiCAR Whitepaper](https://docs.b3.fun/protocol/whitepaper-mica)).

### 3. Tokenomics & Governance
The $B3 token is an ERC-20 utility token on the Base blockchain with a total supply of 100 billion. Its core utilities are **governance**—allowing holders to vote on protocol decisions via the B3 DAO—and **ecosystem commerce**, such as buying in-game items or access passes. Most tokens are subject to long-term vesting schedules ([B3 MiCAR Whitepaper](https://docs.b3.fun/protocol/whitepaper-mica)).

## Conclusion
B3 is fundamentally a performance-optimized, fun-first blockchain layer that leverages Base's security to onboard the next generation of games and apps. Will its focus on developer tooling and cross-chain interoperability be enough to attract mainstream gaming studios?
