The technological architecture of Berachain is an advanced combination of proven blockchain components that ensures high performance, Ethereum compatibility, and modularity.
1. Foundation: Cosmos SDK and CometBFT
Cosmos SDK: Berachain is built on the Cosmos SDK, a framework that allows developers to create custom blockchains from scratch. Using Cosmos SDK gives Berachain modularity, flexibility, and the ability to interact with other blockchains in the Cosmos ecosystem through the Inter-Blockchain Communication (IBC) protocol.
CometBFT (formerly Tendermint Core): For consensus, Berachain uses CometBFT, a high-performance consensus engine that provides security, fault tolerance, and fast transaction finalization. CometBFT is the foundation of many blockchains in the Cosmos ecosystem and is known for its reliability.
2. Execution Environment: Polaris EVM
EVM Identity: A key component of Berachain's architecture is Polaris EVM. Unlike simple EVM compatibility, Polaris EVM aims for 'EVM identity'. This means it mirrors every Ethereum opcode, gas rules, and future updates, allowing developers to port existing Solidity smart contracts and use Ethereum tools (such as MetaMask, Hardhat, Foundry) without any changes.
Modular Design: Polaris EVM is designed as a modular stack that separates the EVM execution layer. This enhances overall usability and allows for the creation of various data layers and configuration frameworks tailored for a wide range of use cases.
Compatibility with Cosmos-Native: Unlike other EVM-compatible solutions on Cosmos (e.g., Ethermint), Polaris recalibrates EVM compatibility capabilities through a Cosmos-native configuration. This ensures full interoperability with the entire Cosmos ecosystem, supporting the next generation of decentralized applications built on Cosmos.
3. Consensus Mechanism: Proof of Liquidity (PoL)
Integration with CometBFT: Proof of Liquidity (PoL) operates on top of CometBFT. Validators providing network security must stake certain liquidity pool assets (LP tokens) as collateral.
Reward Distribution: The PoL mechanism determines how validators are selected to produce blocks (based on delegated BGT) and how rewards are distributed (in BERA and BGT).
"Bribes": Protocols deployed on Berachain can offer 'bribes' to validators to incentivize them to direct BGT emissions to certain liquidity pools. This creates a dynamic economy where protocols can compete for liquidity, and validators and their delegators receive additional rewards.
4. Interaction with dApps and Users:
API and SDK: Berachain provides APIs and SDKs that allow developers to easily create and deploy decentralized applications on the platform.
Standard Liquidity Pool Interfaces: All liquidity pools on Berachain DEX (BEX) adhere to a standard interface, simplifying user interaction.
Wallets: Any wallets that support custom EVM networks (MetaMask, Rabby, Ledger Live) can connect to Berachain.
Overall, the technological architecture of Berachain is the result of careful design that combines the modularity of Cosmos SDK, the performance of CometBFT, the compatibility of Polaris EVM, and the innovative Proof of Liquidity mechanism. This allows Berachain to offer developers and users a powerful, flexible, and highly efficient platform for DeFi applications.#BERA #Binance $BERA
