CEX internal transfers — instant and free between users, one settlement to the real ledger at the end.

The dominant L2 architecture. Optimistic rollups assume transactions are valid and allow 7-day challenge windows; ZK rollups prove validity with cryptographic proofs.
L2 的主流技术。乐观 Rollup 默认交易合法,留 7 天挑战期;ZK Rollup 用数学证明直接验证。
Optimistic = post-trade audit with a claw-back window. ZK = pre-trade math says it's fine, no audit needed.
Optimistic ≈ 事后审计 + 追回期;ZK ≈ 事前数学已证明,不用审。
The node that decides transaction order on an L2. Most are centralized today (single-point failure); decentralizing them is active research.

The matching engine of a CEX — except there's only one, and you have to trust its operator.

Withdrawal fee — except you pay one every time you do anything, not just on exit.
类似提币费 —— 但这里每一次操作都要付,不只是出金。

Kill the order book, price discovery happens along a curve instead.
干掉订单簿,价格在一条曲线上自动发现。

DeFi 版 AUM —— 激励能堆出来,信念才能留得住。
The gap between the expected price and the actual execution price. The shallower the pool, the bigger the bite.
预期成交价和实际成交价之间的差距。池子越浅,被吃掉越多。
Market impact on a thin book — except here the book is a math curve, so impact is fully predictable.

The loss an LP takes when pool prices drift relative to each other — you end up with less value than if you'd just held the two tokens.
LP 的亏损:当池子里两种资产的价格比发生变化,你最终拿回的价值会低于"只是持有这两个币不动"。
The hidden cost of being a market maker — you get paid fees to be short volatility.

Skin-in-the-game replacing electricity-as-security.

Margin trader on the network itself — leveraged conviction in the chain's uptime.
相当于在网络本身上做保证金交易 —— 杠杆押注这条链持续正常运行。
A tradable token representing staked collateral plus accrued yield. stETH (Lido) is the flagship — staked ETH you can still use in DeFi.

A receipt for a locked fixed-deposit that still trades freely on the market.

Rehypothecation, chain-native. Convenient, composable, and structurally fragile if correlations spike.
链上版的"再抵押" —— 方便、可组合,但一旦风险相关性上升,结构性脆弱。
Automatic confiscation of a validator's bonded stake for provable misbehavior. Makes attacks on PoS actually cost something.
当验证者有可证明的作恶行为时,自动没收其抵押金。让攻击 PoS 真正有经济成本。
Liquidation, but for network behavior instead of position health.
相当于强平 —— 只不过强平的是"行为健康度"而不是"仓位健康度"。
The extra value validators can extract by choosing which transactions to include and in what order. Common forms: sandwiching, liquidation racing, cross-DEX arb.
验证者通过决定"哪些交易入块、什么顺序"能榨出的额外价值。常见形式:三明治、抢清算、跨 DEX 套利。
Imagine the matching engine could legally front-run every order book it sees — and does.
想象撮合引擎可以合法抢先交易每一张它看到的订单 —— 而且真的会这么做。
A front-run + back-run pair wrapped around a victim's swap to extract their slippage. Pure profit for the attacker, pure cost to the user.
在受害者的一笔兑换前后各插一单,把受害者的滑点吃干净。攻击者净赚,用户净亏。
Spoofing on steroids — except it's legal here and the venue allows it.
相当于加强版的"幌骗" —— 但在链上它合法,场所默认允许。
Seeing a pending transaction in the mempool and submitting your own with higher priority — often to arbitrage a price move the victim triggers.
看到 mempool 里别人挂着的交易,你用更高优先级的费用插队,赶在它前面成交 —— 经常是套利它会引发的价格变动。
Same as frontrunning in TradFi — just with a public order book every bot can read.
和传统金融的 frontrunning 一模一样 —— 只不过这里的订单簿对所有机器人都是公开的。

Dark pool routing for MEV — extraction still happens, but channeled and less toxic.

Splitting "who proposes a block" from "who chooses what goes into it." Reduces centralization pressure on validators who can't compete with MEV-savvy builders.

A spot wallet tied to one API key. Lose the key, lose everything.
就是一个绑着一把 API key 的现货钱包。Key 丢了就全丢。
A wallet whose logic is a smart contract — enabling batched transactions, social recovery, spending limits, gas sponsorship. Safe, Argent, Coinbase Smart Wallet.

A sub-account with programmable risk controls — like a CEX sub-account you configured yourself.

The standard that gives smart contract wallets first-class status without changing Ethereum's base protocol. The foundation of "wallets that feel normal."

Pluggable account-level risk engine, deployed per user instead of at the exchange.
账户级别的可插拔风控引擎,部署在每个用户身上,而不是在交易所那头。
You declare "I want ETH→USDC at 3800 or better" and a network of solvers competes to fulfill it. You stop worrying about routing, slippage, and chain choice.

A limit order to the whole multi-chain market at once — execution is someone else's problem.
相当于对整个多链市场同时挂一张限价单 —— 怎么成交是别人的事。
