Berachain：使用流動性證明深入研究 EVM 相同的第 1 層區塊鏈

Berachain 是使用 Cosmos SDK 建構的與 EVM 相同的第 1 層區塊鏈網路。它運行在流動性證明（POL）共識機制上。

Berachain is a blockchain network that uses Proof-of-Liquidity (PoL) to separate gas tokens from governance tokens. This allows users to stake assets on Berachain while still being able to use those assets in DeFi protocols.

Berachain 是一個區塊鏈網絡，它使用流動性證明（PoL）將天然氣代幣與治理代幣分開。這允許用戶在 Berachain 上質押資產，同時仍能夠在 DeFi 協議中使用這些資產。

Berachain is also EVM-identical, which means that any EVM (Ethereum Virtual Machine) applications can be deployed on the Berachain network ‘as-is’. Berachain is built with BeaconKit – a modular framework that enables the creation of L1 and L2 chains. As a result, this means Berachain can also support the improvements in the upcoming Dencun upgrade.

Berachain 也與 EVM 相同，這意味著任何 EVM（以太坊虛擬機器）應用程式都可以「原樣」部署在 Berachain 網路上。 Beachain 使用 BeaconKit 構建，BeaconKit 是一個模組化框架，可以創建 L1 和 L2 鏈。因此，這意味著 Berachain 也可以支援即將到來的 Dencun 升級中的改進。

Here's a deeper look at how Berachain works:

以下是對 Berachain 工作原理的更深入了解：

* **Execution Layer: EVM-Identical**

* **執行層：EVM-相同**

Berachain offers an EVM-identical execution environment that allows developers on Ethereum and other EVM networks to port their applications to the networks without making any changes to their code base. Compared to EVM-equivalent and EVM-compatible execution layers, which may require developers to make changes before deploying their apps on these chains, Berachain mirrors the execution environment on Ethereum. This also means that when the EVM is upgraded, Berachain can easily adopt the latest version.

Berachain 提供了與 EVM 相同的執行環境，允許以太坊和其他 EVM 網路上的開發人員將其應用程式移植到網絡，而無需對其程式碼庫進行任何更改。與 EVM 等效和 EVM 相容的執行層（可能需要開發人員在將應用程式部署到這些鏈上之前進行更改）相比，Berachain 鏡像了以太坊上的執行環境。這也意味著當EVM升級時，Berachain可以輕鬆採用最新版本。

* **Consensus Layer: Proof-of-Liquidity (PoL)**

* **共識層：流動性證明（PoL）**

Berachain's approach to solving the on-chain liquidity is its novel Proof-of-Liquidity (PoL) consensus mechanism. PoL is an adaptation of the established PoS consensus mechanism with a significant modification in the staking process, asset management, and reward distribution.

Berachain解決鏈上流動性的方法是其新穎的流動性證明（PoL）共識機制。 PoL 是現有 PoS 共識機制的改編，在質押流程、資產管理和獎勵分配方面進行了重大修改。

For one, it introduces a multi-token structure to separate the security and governance systems. It also aims to support the network's economy while building a sufficient value layer for the consensus system.

其一，它引進了多代幣結構來分離安全和治理系統。它還旨在支持網路經濟，同時為共識系統建立足夠的價值層。

In the Berachain network, two types of tokens are used for gas fees and on-chain governance, respectively. BERA is the gas token, while BGT is the governance token. Both tokens are non-transferable and are obtained by staking BERA and other supported assets in the reward vaults. BERA is used to pay for regular and smart contract transactions, while BGT is used to participate in the network's governance. Stakers can choose to stake either BERA or other assets, such as LP tokens, in the reward vaults.

在 Berachain 網路中，兩種類型的代幣分別用於 Gas 費用和鏈上治理。 BERA 是 Gas 代幣，而 BGT 是治理代幣。這兩種代幣都是不可轉讓的，是透過在獎勵金庫中質押 BERA 和其他支持的資產來獲得的。 BERA 用於支付常規交易和智能合約交易，而 BGT 用於參與網路治理。質押者可以選擇在獎勵金庫中質押 BERA 或其他資產，例如 LP 代幣。

The BGT emissions are then allocated to the reward vaults chosen by the validators based on the incentives offered by the DeFi protocols. These protocols typically offer an exchange rate between the BGT emitted to the vault and another token. For example, a DEX may offer 10 of its native tokens for every 1 BGT emitted to its vault.

然後，BGT 排放量將分配到驗證者根據 DeFi 協議提供的激勵措施選擇的獎勵金庫。這些協議通常提供發送到金庫的 BGT 與其他​​代幣之間的匯率。例如，DEX 可以為向其金庫發送的每 1 BGT 提供 10 個原生代幣。

After the BGT emissions are allocated to the vaults, users can lock their assets in the vaults to earn a share of the BGT emissions. The portion of BGT emissions that each user receives is determined by the amount of their assets locked in the vault relative to the total assets in the vault. For example, if a user locks 100,000 BERA in a vault that receives 1,000 BGT emissions, the user will earn 100 BGT.

BGT排放量分配到金庫後，使用者可以將資產鎖定在金庫中，以賺取BGT排放量的份額。每個使用者收到的 BGT 排放部分取決於其鎖定在金庫中的資產相對於金庫中總資產的數量。例如，如果使用者將 100,000 BERA 鎖定在接收 1,000 BGT 排放量的金庫中，則該使用者將獲得 100 BGT。

Once the BGT emissions are distributed to the users, they can use their BGT to participate in the network's governance by voting on improvement proposals. BGT holders can also choose to delegate their voting powers to any other address.

一旦 BGT 排放量分配給用戶，他們就可以使用 BGT 透過對改進提案進行投票來參與網路的治理。 BGT 持有者也可以選擇將投票權委託給任何其他地址。
