Berachain V2 marks a pivotal evolution in blockchain architecture, redefining how scalability, developer experience, and user incentives converge on a modular Layer 1 network. As one of the most anticipated upgrades in the decentralized ecosystem, V2 addresses core limitations of its predecessor while amplifying Berachain’s unique value proposition: Proof of Liquidity (PoL). This upgrade isn’t just technical refinement—it’s a strategic leap toward sustainable DeFi growth, seamless EVM integration, and community-driven security.
Understanding Berachain: A Modular L1 with Purpose
Berachain is a modular, Ethereum-compatible Layer 1 blockchain powered by CometBFT consensus. Unlike traditional Proof of Stake (PoS) chains that struggle with fragmented liquidity and suboptimal validator alignment, Berachain introduces an innovative economic model designed to unify network participants.
At the heart of this design is Proof of Liquidity, a consensus mechanism that aligns validators, users, and decentralized applications (dApps) around shared incentives. In conventional blockchains, liquidity often becomes siloed within isolated protocols—leading to inefficiencies and reduced capital velocity. Berachain solves this by embedding liquidity directly into its consensus layer.
The protocol operates on a tri-token system:
- BERA: The native gas token used for transaction fees and validator bonding.
- BGT: A non-transferable governance and rewards token earned through active participation.
- HONEY: A stablecoin used within Berachain’s DeFi ecosystem.
Through PoL, validators earn BGT not just by staking, but by facilitating liquidity across core DeFi primitives like AMM DEXs, lending platforms, and perpetual futures exchanges. This creates a self-reinforcing flywheel: more liquidity strengthens security, which attracts more dApps and users, further amplifying liquidity.

Proof of Liquidity: The Engine Behind V2
While many blockchain upgrades focus solely on speed or cost reduction, Berachain V2 doubles down on its foundational philosophy—incentive alignment through liquidity. PoL ensures that every action taken on the network contributes to its overall health.
For example:
- Users providing liquidity earn HONEY and contribute to BGT generation.
- Validators who support high-liquidity applications receive greater BGT delegation.
- dApps benefit from native access to capital and user engagement driven by protocol-level rewards.
This creates a symbiotic relationship where economic activity directly fuels network security. As more users interact with DeFi protocols on Berachain, the system generates more BGT, which in turn increases validator rewards and strengthens decentralization.
Crucially, V2 preserves this model while enhancing its execution efficiency—ensuring that PoL remains effective even as the network scales.
BeaconKit: Powering EVM Identity and Scalability
One of the most significant technical advancements in Berachain V2 is the introduction of BeaconKit, a modular framework that replaces the legacy Polaris Virtual Machine. This shift transitions Berachain from EVM-compatible to EVM-identical, offering developers a seamless experience identical to Ethereum’s execution environment.
Why EVM Identity Matters
In V1, Berachain relied on Polaris—a custom EVM implementation tightly coupled with CometBFT consensus. While innovative, this design led to performance bottlenecks during peak usage on the Artio testnet, particularly due to mempool congestion and slow block finality.
V2 resolves these issues by decoupling consensus and execution using BeaconKit, inspired by Ethereum’s transition to the Consensus Layer (formerly ETH2). This modular approach allows Berachain to:
- Support any Ethereum execution client (e.g., Geth, Reth, Nethermind).
- Achieve single-slot finality, drastically reducing confirmation times.
- Eliminate precompile overhead, enabling out-of-the-box EVM equivalence.
Developers can now deploy Ethereum-native smart contracts without modifications, reducing friction and accelerating time-to-market for new projects.
Enhanced Developer Flexibility
BeaconKit also supports EIP-4844 (Proto-danksharding), paving the way for future Layer 2 rollups by reducing data availability costs via “blob” transactions. Combined with ABCI 2.0 compatibility, this enables integration with frameworks like Rollkit—empowering teams to build scalable L2s anchored to Berachain’s secure L1.
This modularity doesn’t complicate the user experience; instead, it runs invisibly beneath the surface, ensuring smooth interactions regardless of underlying complexity.

Validator Upgrades and Staking Enhancements
Berachain V2 introduces key changes to validator dynamics, reinforcing network security and decentralization:
- Increased Validator Cap: The maximum number of active validators rises from 100 to a soft limit of 256, promoting greater decentralization.
- BERA Activation Bond: Validators must now stake BERA to activate their node—ensuring skin in the game and protecting against spam attacks.
- BGT Delegation Mechanics: Validators start with zero BGT weight. BGT is earned exclusively through ecosystem participation (e.g., liquidity provision), and delegation cannot be slashed—only the BERA bond is at risk.
Block production remains probabilistic—every validator has an equal chance to propose a block. However, rewards scale proportionally with delegated BGT, incentivizing validators to support high-activity dApps and foster vibrant ecosystem growth.
This structure ensures that validators are not just passive stakers but active contributors to liquidity health—aligning perfectly with PoL’s core ethos.
Modularity with a Human Touch
Many modular blockchains prioritize technical elegance over usability. Berachain V2 flips this script by making modularity serve the user—not the other way around.
The platform abstracts complex architectural decisions so that:
- Users enjoy fast, low-cost transactions without understanding consensus layers.
- Developers deploy familiar Ethereum tooling without learning new paradigms.
- dApps tap into native liquidity without relying on external incentives.
This user-first approach positions Berachain as more than a tech upgrade—it’s a new model for sustainable blockchain ecosystems.

Frequently Asked Questions (FAQ)
Q: What is Proof of Liquidity (PoL)?
A: PoL is Berachain’s unique consensus mechanism that ties network security to liquidity provision. Validators, users, and dApps all earn rewards based on their contribution to ecosystem liquidity, creating a self-sustaining economic loop.
Q: How does Berachain V2 differ from V1?
A: V2 replaces the Polaris VM with BeaconKit, achieving EVM identity, single-slot finality, and support for multiple execution clients. It also increases validator capacity and refines staking mechanics for improved decentralization.
Q: Is Berachain fully EVM-compatible?
A: Yes—Berachain V2 is EVM-identical, meaning developers can deploy unmodified Ethereum smart contracts with full compatibility.
Q: Can I transfer BGT tokens?
A: No. BGT is non-transferable and earned only through active participation in the ecosystem, such as providing liquidity or running a validator.
Q: What role does EIP-4844 play in Berachain V2?
A: EIP-4844 enables cheaper data posting for rollups via blob transactions, laying the groundwork for scalable L2 solutions built on BeaconKit-powered chains.
Q: How do validators earn rewards in V2?
A: Validators earn block rewards proportional to their delegated BGT. Since BGT is earned through ecosystem engagement, validators are incentivized to support active dApps and maintain strong liquidity.
Final Thoughts: Beyond an Upgrade
Berachain V2 is not merely a technical refresh—it’s the realization of a vision where blockchain security, scalability, and user empowerment are unified through economic alignment. By combining EVM identity with Proof of Liquidity and modular execution via BeaconKit, Berachain sets a new standard for what a Layer 1 can achieve.
