Annual Percentage Rate (APR) is an annualized percentage rate that represents investment returns or borrowing costs, calculated using simple interest without accounting for compounding effects. In cryptocurrency, APR is commonly used to measure annualized yields from staking, lending, and liquidity provision activities, helping users evaluate and compare investment benefits across different DeFi protocols.

Amalgamation refers to the strategic action in the blockchain and cryptocurrency industry where two or more independent entities (such as projects, protocols, companies, or foundations) combine their respective assets, technologies, teams, and communities through acquisition, merger, or integration. Amalgamations can be categorized as horizontal (integration of similar projects) or vertical (integration of projects with different functions), resulting in complete absorption, equal mergers, or the formation

In blockchain technology, Asynchronous refers to the characteristic where nodes in a network can receive messages and execute operations at different times without waiting for other operations to complete. In asynchronous systems, time delays are unbounded and message delivery has no definite time guarantees, contrasting with synchronous systems that require operations to execute in fixed order or simultaneously.

Annual Percentage Yield (APY) is a financial metric that represents the total rate of return an investment might earn over a year when accounting for the effect of compounding. In cryptocurrency, it's commonly used to express the expected return rate on DeFi products such as staking, lending platforms, or liquidity pools, with compounding effects already calculated, allowing investors to intuitively compare the earning potential across different protocols.

A coin is a cryptocurrency that operates on its own independent blockchain network, typically used for store of value, medium of exchange, and unit of account. Coins are issued through consensus mechanisms such as mining or proof-of-stake, featuring decentralization, security, and programmability, representing the base currency layer in blockchain ecosystems.

Cryptocurrency Market Cap is a metric measuring the economic size of crypto assets, calculated by multiplying the circulating token supply by the current market price. As the fundamental valuation standard for digital assets, market cap is categorized into total market cap (all tokens) and circulating market cap (tradable tokens), serving as the primary reference for assessing project scale and overall crypto market conditions.

Dead Cat Bounce is a term in financial and cryptocurrency markets that describes a temporary, brief recovery in the price of an asset following a substantial decline, after which the downward trend continues.

累计（Accrue）是指在加密资产领域，利息、奖励或收益随着时间推移而逐步积累的过程。这一概念主要应用于DeFi借贷平台、流动性挖矿和质押系统，通过智能合约自动计算并分配收益，可按区块高度或实际时间间隔进行累算。

可替代性是指资产、商品或货币单位在价值和功能上完全相同并可相互交换的特性。在加密货币领域，可替代性意味着每个单位与同类其他单位完全等同，没有独特标识或特征，使其能够作为交换媒介有效流通。

杠杆是一种金融工具，允许交易者使用借入资金放大其交易头寸规模，以较小的初始资本控制更大价值的资产。在加密货币交易中，杠杆通常以倍数表示（如2倍至125倍不等），代表交易者可以控制超出其实际资金的头寸大小，同时既放大潜在收益也放大潜在风险。

一次性使用的数字(nonce)是区块链技术中一个仅使用一次的任意数值，主要用于工作量证明(PoW)挖矿过程。矿工通过不断调整nonce值并进行哈希计算，直到找到满足网络难度要求的哈希值，从而验证区块有效性并获得挖矿奖励。在区块头中，nonce占据4字节空间，允许测试约43亿个可能值。

定义收款人是指在区块链交易过程中，确定加密资产接收方的地址或标识符。收款方通常表现为由公钥衍生的字符串地址，是加密货币转账的目标终点。不同区块链网络采用不同的地址格式，如比特币地址以1或3开头，以太坊地址以0x开头。

托儿是指在加密货币领域中，个人或群体为了个人利益而过度宣传或推广特定加密项目、代币或币种的行为，通常缺乏客观分析并故意隐瞒风险，目的是吸引新投资者入场，抬高价格使早期持有者获利。

A Degen (short for Degenerate) refers to a market participant in the cryptocurrency space who engages in high-risk speculative behaviors, typically seeking short-term massive profits by allocating substantial capital to unproven projects, leveraged trading, or emerging tokens while often disregarding fundamental analysis and risk management principles. This group is characterized by chasing market trends, participating in early-stage projects, and accepting extreme volatility.

An Epoch is a predefined unit of time or block count in blockchain networks, representing a complete cycle of network activity. During this period, the blockchain performs a specific set of operations such as updating validator sets, distributing staking rewards, or adjusting difficulty parameters. The length of epochs varies across different blockchain protocols and may be defined either by time (hours or days) or by block count (such as 32,768 blocks).

Etherscan is an independently developed Ethereum block explorer and analytics platform that allows users to search, view, and verify transactions, addresses, tokens, prices, and other activities on the Ethereum blockchain, providing transparency and accessibility to the Ethereum network.

Fear of Missing Out (FOMO) refers to the anxiety investors feel about potentially missing profitable opportunities, which drives them to make irrational investment decisions. In cryptocurrency trading, FOMO typically manifests as investors blindly buying assets after prices have already significantly increased, hoping to share in the market's upward momentum.

The iShares Bitcoin Trust (IBIT) is an exchange-traded fund (ETF) that directly tracks the spot price of Bitcoin, managed by BlackRock and listed on the Nasdaq exchange.

Leverage refers to the practice where traders borrow funds to increase the size of their trading positions, controlling assets of greater value with smaller capital. In cryptocurrency trading, leverage is typically expressed as a ratio (such as 3x, 5x, 20x, etc.), indicating the multiple of the original investment that a trader can control in assets. For example, using 10x leverage means an investor can control assets worth $10,000 with just $1,000.

NFT (Non-Fungible Token) is a unique digital asset based on blockchain technology, characterized by its indivisible and irreplaceable nature, with each NFT possessing a unique identification code and metadata. They are typically created following standards like Ethereum's ERC-721 or ERC-1155, capable of definitively proving ownership, authenticity, and scarcity of digital content.
