关于 Ethereum About Ethereum

Ethereum

Ethereum（ETH）是首个实现了智能合约功能的去中心化区块链平台，于 2015 年由 Vitalik Buterin 等人创建。它不仅是数字货币，更是一个可编程的平台，允许开发者构建和部署去中心化应用（DApp）、DeFi 协议和 NFT 市场。 Ethereum (ETH) is the first decentralized blockchain platform with smart contract functionality, created in 2015 by Vitalik Buterin and others. It's not just a digital currency but a programmable platform that allows developers to build and deploy decentralized applications (DApps), DeFi protocols, and NFT marketplaces.

Ethereum 采用权益证明（PoS）共识机制，验证者通过质押 ETH 来维护网络安全。2022 年完成的「合并」（The Merge）使 Ethereum 从工作量证明转变为权益证明，功耗降低约 99.95%。ETH 是网络的原生货币，用于支付 gas 费用和质押。 Ethereum uses a Proof of Stake (PoS) consensus mechanism where validators maintain network security by staking ETH. The Merge in 2022 transitioned Ethereum from Proof of Work to Proof of Stake, reducing power consumption by approximately 99.95%. ETH is the native currency used to pay gas fees and for staking.

常见问题 Frequently Asked Questions

Ethereum 的工作原理是什么？ How does Ethereum work? +
Ethereum 是一个去中心化的区块链平台，通过以太坊虚拟机（EVM）执行智能合约。用户可以用 ETH 支付 gas 费用，在网络上部署应用、发送交易和存储数据。以太坊采用权益证明（PoS）共识机制，由验证者代替矿工来维护网络安全。 Ethereum is a decentralized blockchain platform that executes smart contracts through the Ethereum Virtual Machine (EVM). Users pay gas fees with ETH to deploy applications, send transactions, and store data on the network. Ethereum uses a Proof of Stake (PoS) consensus mechanism where validators replace miners to maintain network security.
如何存储 Ethereum 最安全？ What is the safest way to store Ethereum? +
存储 Ethereum 最安全的方式是使用硬件钱包，如 Keystone。硬件钱包将私钥存储在安全芯片中，完全与网络隔离（气隙隔离），有效防止黑客攻击和恶意软件威胁。相比热钱包，硬件钱包提供企业级的安全保护。 The safest way to store Ethereum is using a hardware wallet like Keystone. Hardware wallets store private keys in a secure chip completely isolated from the internet (air-gapped), effectively preventing hacker attacks and malware threats. Compared to hot wallets, hardware wallets provide enterprise-grade security.
ETH 和 BTC 有什么区别？ What's the difference between ETH and BTC? +
Bitcoin 主要作为一种去中心化的数字货币和价值存储手段，而 Ethereum 则是一个可编程的智能合约平台。ETH 不仅是一种加密货币，还用作支付 gas 费用来驱动网络上的各种操作，包括 DeFi、NFT 和去中心化应用。 Bitcoin primarily serves as a decentralized digital currency and store of value, while Ethereum is a programmable smart contract platform. ETH is not only a cryptocurrency but also used to pay gas fees to power various operations on the network, including DeFi, NFTs, and decentralized applications.
什么是 Ethereum 的 gas 费用？ What are Ethereum gas fees? +
Gas 是 Ethereum 网络上执行操作所需的计算费用。用户需要用 ETH 支付 gas 费用来发送交易或执行智能合约。gas 价格会根据网络拥堵程度波动，在高峰期可能非常高。Keystone 硬件钱包会在签名前清晰显示预估 gas 费用。 Gas is the computational fee required to execute operations on the Ethereum network. Users need to pay gas fees with ETH to send transactions or execute smart contracts. Gas prices fluctuate based on network congestion and can be very high during peak periods. Keystone hardware wallet displays estimated gas fees clearly before signing.
什么是 Ethereum 的质押（Staking）？ What is Ethereum staking? +
质押是将 ETH 存入验证节点以帮助维护网络安全并获得奖励的过程。Ethereum 采用权益证明（PoS）机制，验证者锁定 ETH 作为担保来生产新区块。质押的 ETH 可以通过 Liquid Staking 产品获得流动性代币，如 stETH 和 rETH。 Staking is the process of depositing ETH into validator nodes to help maintain network security and earn rewards. Ethereum uses a Proof of Stake (PoS) mechanism where validators lock ETH as collateral to produce new blocks. Staked ETH can obtain liquidity tokens through Liquid Staking products like stETH and rETH.
Ethereum 支持哪些类型的代币？ What types of tokens does Ethereum support? +
Ethereum 是 ERC-20 代币标准的发源地，支持数千种同质化代币（FT），以及 ERC-721（NFT）、ERC-1155（多代币标准）等。Keystone 硬件钱包全面支持这些 Ethereum 代币标准，让用户安全管理各类资产。 Ethereum is the origin of the ERC-20 token standard, supporting thousands of fungible tokens (FT), as well as ERC-721 (NFT), ERC-1155 (multi-token standard), and more. Keystone hardware wallet fully supports these Ethereum token standards, allowing users to securely manage various asset types.
Keystone 如何保护我的智能合约交互安全？ How does Keystone protect my smart contract interactions? +
在使用 MetaMask 等钱包连接 DeFi 协议或签署交易时，Keystone 的 4 英寸大屏幕会完整显示合约调用的详细信息，包括目标合约地址、调用方法、参数数值和预估 gas 消耗。你可以在硬件设备上逐一验证后再授权，完全隔绝计算机恶意软件的入侵路径。 When connecting to DeFi protocols or signing transactions with wallets like MetaMask, Keystone's 4-inch screen displays complete details of the contract call, including the target contract address, method called, parameter values, and estimated gas. You can verify each item on the hardware device before authorizing, completely isolating the attack vector from computer malware.
Keystone 支持哪些 Ethereum 二层网络（L2）？ Which Ethereum L2 networks does Keystone support? +
Keystone 支持所有基于 EVM 的二层网络，包括 Arbitrum、Optimism、Base、Polygon、zkSync、Linea、Scroll 等。你可以通过同一套助记词管理多个 L2 链上的资产，Keystone 会清晰显示每笔交易所在的网络和链 ID，防止跨链签名攻击。 Keystone supports all EVM-based L2 networks including Arbitrum, Optimism, Base, Polygon, zkSync, Linea, Scroll, and more. You can manage assets across multiple L2 chains using the same recovery phrase, and Keystone will clearly display the network and chain ID for each transaction, preventing cross-chain signature attacks.
如何安全地授权代币给 DeFi 协议？ How to safely approve tokens to DeFi protocols? +
授权代币给 DeFi 协议是一个高风险操作，恶意协议可能借此耗尽你的资产。Keystone 在签名前会明确显示授权的代币数量、授权目标地址和是否支持无限授权。你还可以随时通过 Keystone 撤销已授权的代币额度，全程无需联网。 Approving tokens to DeFi protocols is a high-risk operation—malicious protocols could drain your assets. Keystone displays the approved token amount, spender address, and whether it supports unlimited approval before signing. You can also revoke approved token allowances through Keystone without ever connecting to the internet.
Keystone 支持 ENS 域名吗？ Does Keystone support ENS domains? +
支持。Keystone 可以解析 ENS 域名并在交易确认页面显示对应的以太坊地址。当你向 ENS 域名转账时，设备会同时显示解析后的实际地址和域名本身，帮助你验证目标地址的正确性，防止钓鱼攻击。 Yes. Keystone can resolve ENS domains and display the corresponding Ethereum address on the transaction confirmation screen. When transferring to an ENS domain, the device shows both the resolved address and the domain name itself, helping you verify the correctness of the target address and prevent phishing attacks.
如果丢失 Keystone 设备，我的 Ethereum 还能找回吗？ If I lose my Keystone device, can I still recover my Ethereum? +
可以。Keystone 支持 BIP-39 标准助记词，你可以使用 12/18/24 个单词的助记词在任何兼容的钱包（如 MetaMask、Rabby）中恢复你的 ETH 和代币资产。助记词同时兼容以太坊主网和所有 EVM 兼容链上的账户。 Yes. Keystone supports BIP-39 standard recovery phrases. You can recover your ETH and tokens using 12/18/24 word phrases in any compatible wallet (such as MetaMask or Rabby). The recovery phrase is compatible with accounts on both Ethereum mainnet and all EVM-compatible chains.
