In a year marked by relatively few captivating projects, Berachain has cultivated a devoted, almost cult-like following, seamlessly merging meme culture with tangible value.
While its success is often credited to astute marketing and community-building tactics, the underlying innovation fuels the excitement. At the heart of Berachain's allure lies Proof of Liquidity (POL), a groundbreaking consensus model that harmonizes the incentives of all network participants - validators, applications, and users - fostering a synergistic ecosystem.
This model is poised to enhance interoperability and cooperation within the Berachain ecosystem, streamlining the launch of new projects and bootstrapping liquidity.
In a fiercely competitive landscape, where numerous platforms vie for user attention and dominance, POL represents a notable experiment in incentivizing network participation.
Throughout this analysis, I will delve deeper into Berachain, situating POL within the broader evolution of consensus mechanisms. Subsequently, I will examine its practical implications for projects developing within the Berachain ecosystem, utilizing some of the most prominent ones as illustrative use cases.
What is Berachain?
Berachain is a foundational blockchain (Layer 1) that sets itself apart through its innovative Proof of Liquidity (POL) consensus model. This model empowers participants to utilize their liquidity as a security mechanism for the network.
This approach diverges significantly from the prevailing trend of constructing Layer 2 solutions on Ethereum or creating independent application-specific blockchains (app-chains) and Layer 3 networks.
Berachain's strategic decision to establish itself as a Layer 1 blockchain is intrinsically tied to the unique advantages offered by its POL consensus mechanism. Unlike traditional blockchains, Berachain prioritizes the presence of collaborative incentives at the consensus layer, rather than solely focusing on technical specifications or performance metrics.
Berachain operates with a Byzantine Fault Tolerant (CometBFT) consensus mechanism, ensuring single-slot finality while maintaining compatibility with the Ethereum Virtual Machine (EVM). This compatibility allows developers to build on Berachain without requiring substantial modifications to their existing code. Several projects have already expressed interest in constructing Layer 2 solutions on Berachain.
Furthermore, Berachain's modular architecture, underpinned by BeaconKit, separates consensus from the execution layer. This enables integration with Ethereum execution clients, such as Geth or Reth, without necessitating significant adaptation.
Despite initial skepticism, Berachain has firmly established itself as a credible and promising force within the blockchain landscape. Since its inception in the first quarter of 2022, Berachain has secured over 150 million dollars through Series A and B funding rounds, raising expectations for its launch. The Bartio testnet V2 was deployed in June 2024, with the mainnet launch anticipated in the fourth quarter of 2024.
Before delving into the complexities of POL, it is essential to comprehend the historical context that precipitated its emergence.
Over time, blockchain consensus models have undergone significant evolution, driven by the imperative to address the blockchain trilemmaābalancing security, speed, and decentralization. Early models primarily focused on ensuring the correct functioning of decentralized systems, while more recent innovations aim to align the incentives of network participants from the outset.
Bitcoin pioneered the Proof-of-Work (PoW) consensus model, which necessitated miners to expend computational resources (energy) to solve complex mathematical problems and validate new blocks.
This model was revolutionary in its ability to align the incentives of self-interested actors within a decentralized system. However, PoW's energy-intensive nature and reliance on specialized hardware have raised concerns about sustainability and miner centralization.
In response, alternative models such as Proof-of-Stake (PoS) have gained traction. Ethereum, for instance, transitioned from PoW to PoS in 2022. PoS secures the network using native tokens as collateral ("stake"), with validators risking their stake getting slashed in case of malicious behavior.
Delegated Proof of Stake (DPoS) further allows users to delegate their stake to validators, adding flexibility to the system.
Despite their strengths, PoW, PoS, and DPoS share certain limitations. Two of the most significant issues are:
The lack of involvement for other participants aside from validators
The lack of incentive alignment across different ecosystem participantsāvalidators, applications, and users often operate with divergent goals.
This absence of collaboration has prompted the development of new consensus models that align all stakeholders from the outset, supporting and driving value to applications, with POL being a prime example.
Compared to the previous consensus models, POL block rewards are shared not only with validators but also with applications and users. This way, applications can also benefit from the chain native emission as a source of yield and incentivize user liquidity.
In the next section, I will explore POL in more detail, introducing the concept and explaining how this consensus model provides several advantages for projects building on Berachain.
To grasp the intricate balance of incentives fostered by POL, it's crucial to understand Berachain's token model, composed of three distinct tokens:
BGT (Bera Governance Token): The cornerstone of POL, BGT is a non-transferable token exclusively earned by validators as block rewards. Users can acquire BGT by engaging in specific actions within authorized decentralized applications (dApps), such as providing liquidity to liquidity pools (LPs) or borrowing assets. Once obtained, BGT can either be converted into BERA or delegated to validators.
BERA: Berachain's native gas token, BERA must be staked by participants aspiring to become validators. It is transferable and can be procured by burning BGT tokens.
HONEY: A stablecoin native to Berachain, pegged 1:1 to the US dollar. HONEY is minted by depositing approved collateral into a vault.
By differentiating these tokens, Berachain effectively separates gas/security functions (BERA) from chain rewards (BGT), ensuring that various aspects of the ecosystem are incentivized appropriately.
POL embodies Berachain's innovative approach to consensus, designed to harmonize the interests of validators, developers, and users.
Building upon DPoS, it incorporates a soul-bound token (BGT), which:
Determines a validator's reward weight based on delegation
Incentivizes liquidity provision through reward vaults
To gain prominence in an increasingly competitive ecosystem, networks have extensively employed incentives to attract applications and users.
In contrast to traditional incentive mechanisms, which often rely on short-term grants or subsidies, POL shifts the focus of incentives to the long-term, embedding a native incentive system directly into the consensus model.
This ensures that network security and application liquidity mutually reinforce each other, acting as a catalyst for Berachain's application layer, which benefits from native incentives.
Through these efforts, Berachain's architecture is constructed with a consumer-centric approach and deeply ingrained collaboration among all network participants:
Under a POL model, users delegate BGT to Validators. Based on the amount of tokens delegated to them, a Validator will have a certain reward weight, representing the percentage of rewards it will receive from the total emission. Validators earn a fee from these rewards.
When a Validator successfully creates a new block, it receives block rewards in BGT tokens and HONEY. Validators then distribute BGT rewards in reward vaults to users according to the liquidity provided in the pool and HONEY directly to users.
In this way, validators can direct BGT to specific pools, promoting decentralized token emissions and stakeholder alignment.
Eligibility: Potential validators must stake a specific amount of BERA (subject to change) to qualify for block production.
Block Proposal: For each new block, a random Active Validator is selected to propose the block.
Reward Distribution: The chosen validator receives an allocation of BGT, which they distribute to various reward vaults based on the incentives received.
Liquidity providers can deposit a specific token into a BEX pool. In return, they receive a receipt token, which they can stake in a designated reward vault to become eligible for BGT rewards. The receipt token represents the LP tokens that users can stake in the BGT station to qualify for BGT rewards (only whitelisted pools are eligible). Liquidity Providers have the option to claim the distributed BGT rewards. They can either delegate these rewards to an active validator for additional incentives or convert them into BERA to make them transferable.
Following these incentives, something interesting is happening: Many Berachain applications are deploying their own validators, such as Infrared, Kodiak, and The Honey Jar, which are currently the validators with the most BGT delegated to them.
This model creates new opportunities for collaboration among validators, protocols, and users, each driven by their own self-interest:
Validators: Aim to maximize BGT rewards and attract delegations.
Applications: Seek to increase BGT rewards for their pools to incentivize user liquidity.
Users: Desire to earn higher rewards by depositing liquidity in pools or delegating to validators.
Initially, the Bera Foundation plays a pivotal role as the ecosystem steward, operating default dApps (Bex, Bend, Berps) and redistributing fees to BGT holders, thereby stimulating initial demand until more protocols emerge.
Validators assume a more active role in this system, influencing the distribution of BGT emissions across various liquidity pools and applications. Simultaneously, validators strive to maximize BGT delegations to increase their reward weight. This dynamic serves as an indirect check and balance on validators' power, ensuring they prioritize the interests of their delegators.
The liquidity from these initial applications will also be used as the default Reserve Vaults:
BEX - Specific BEX Pools
Bend - Borrow $HONEY
Berps - Depositing $HONEY into Berps Honey Vault
Creating new vaults is permissionless, but to be eligible to receive BGT form validators, they must go through the Whitelisting Process by BGT governance.
To achieve these benefits, actors must work together from the outset through a clever game theory system.
Proof of Liquidity introduces a paradigm shift from a zero-sum competition to a collaborative, ecosystem-wide cycle.
A prime example of this system in action is the relationship between validators and protocols. All protocols on Berachain vie for BGT rewards from block production. Beyond securing the network, validators must:
Maximize their BGT delegations
Strategically distribute BGT incentives
Validators determine which protocols and gauges to prioritize based on various factors, including incentive distribution (profitability), user popularity (social alignment), and alignment with delegator interests.
Berachain's applications can incentivize validators by offering native tokens as bribes, encouraging them to direct BGT rewards towards specific pools. This fosters a virtuous cycle where validators, applications, and users collaborate to optimize rewards and promote decentralized liquidity provision.
This also leads to a transformation in how POL impacts an application's tokenomics. Thanks to the native incentive system, Berachain protocols can effectively utilize BGT emissions to subsidize costs and reward users, reducing the need for token inflation.
The POL model addresses traditional challenges faced by Liquidity Providers by offering multiple revenue streams:
BGT distribution from Validators
LP rewards
Additional incentives from bribes
Indirectly increasing governance power through BGT accumulation
Moreover, POL assists applications in bootstrapping liquidity and deposits by enabling them to offer bribes to validators to attract liquidity. This approach allows projects to leverage the chain's native emissions as a yield source rather than relying on paying liquidity providers.
The POL model presents a sustainable solution for ecosystem growth. It empowers projects to utilize chain-native emissions instead of relying on short-term incentives or mercenary capital. This collaborative incentive structure fosters long-term growth and ecosystem alignment.
Users play a pivotal role in this system by voting with their wallets. Users deposit liquidity into whitelisted pools and receive LP tokens. These LP tokens can be staked in specific pools to earn BGT, which is then delegated to validators. Users can delegate to validators aligned with their preferences, such as those supporting specific applications, highlighting the importance of validator involvement within the ecosystem.
Through its unique design, the POL model facilitates a comprehensive alignment of interests among all participants, leading to a flywheel effect that enhances value creation within the Berachain ecosystem.
