进入区块链的大门 — — 取消钱包授权(第五讲)
前面我们有讲到不同钱包的使用方法,和如何访问Dapp。对于经常访问Dapp和使用DeFi应用的人们来说,若想在DeFi协议上使用代币,‘’代币授权‘’是经常性的步骤。什么是代币授权?以太坊链、EVM链(BSC/HECO/OKExChain/Polygon等)和波场链上的Dapp大都涉及到合约操作,授权即表示允许该合约地址提取用户的代币。Dapp需要访问代币才能需要对其操作。比如你想在uniswap卖掉WBTC,则需要‘’Approve‘’ Uniswap的智能合约访问你钱包内WBTC的权限,然后才能通过第二笔交易把WBTC转换成其他代币。在钱包上面,你可以看到该授权。为了提升用户体验,减少授权次数,Dapp会要求无限授权,即该智能合约有权对钱包内的某个币种有不限量的转移权限。对于靠谱的知名平台,如uniswap等,不会恶意操作转移用户的钱包资产。如果该Dapp一开始就是恶意的,则该钱包对于已经授权该平台的所有币种都有极大的安全隐患。即便是成熟的项目,也有可能存在漏洞而被攻击者利用。所以一旦用户给Dapp授权,钱包的该代币就会陷入风险。 虽然硬件钱包可以保护私钥,并且没有人能绕过硬...
进入区块链的大门 — — 网页插件钱包(第三讲)
我们前面讲到了加密货币钱包的概览,上一讲是关于imtoken钱包的使用。本讲的主要内容是Metamask。metamask 有两个版本,一个是在谷歌浏览器chrome的以太坊钱包插件,也是最常用的,另一个是手机的app。这里主要讲最常用的chrome浏览器插件版。 1. 下载谷歌浏览器:https://www.google.com/chrome/ 记住一定要在官网下载,或者在有保障的平台下载,不要下载未知源头下载的谷歌浏览器。 2. 下载metamask的chrome浏览器插件 metamask的官方网站为https://metamask.io/ 点击下载,然后选择Chrome, Install metamask for chrome 这个时候就会跳转到chrome商店然后添加插件到chrome浏览器就可以了。 安装完成后,浏览器的插件栏会出现metamask小狐狸图标,安装完成可以开始使用。 3. 开始使用生成钱包根据引导一步一步走,点击”开始使用”2. 导入或者创建 根据你的钱包习惯,喜欢用自己老的钱包去作为metamask钱包的话,可以直接用助记词导入钱包,在metamas...
进入区块链的大门 — — 硬件钱包的使用(第四讲)
我们前面讲到了加密货币钱包的概览,imtoken和metamask的使用。本讲的主要内容是硬件钱包 — ledger nano X的使用。 为什么选择Ledger? Ledger是法国的硬件钱包品牌,是目前销量最大的硬件钱包。产品经过了市场和安全机构的验证,使用方便。Ledger目前有三款产品,是ledger nano S,Ledger nano S plus 和 ledger nano X。Ledger nano S 只能连接电脑端并且最多安装3个币种的app。Ledger nano X 可以连接电脑端,并且可以通过蓝牙连接手机端。存储空间大,可以同时安装几十个app。因为Ledger nano X可以连接手机,适合对于操作频繁的用户购买。Ledger nano S plus则是 Ledger nano S的升级款,也可以同时安装几十个app,但是无法通过蓝牙与手机连接。在这里我推荐用户购买ledger nano S plus 或者ledger nano X,用户可以按需购买。为了保证安全,这里硬件设备只推荐从官网购买,因为无法判定其他经销商的真伪。避免因为买到假的硬件钱包或者...

Aptos, based in Palo Alto, California, is a public blockchain that aims to solve reliability, scalability, and usability issues that have plagued existing Layer 1s, whilst possessing security features lacking in EVM-based blockchains. Aptos uses Move, a Rust-based programming language created for Diem, a now abandoned blockchain project by Meta.
The Aptos network can achieve over 130k transactions per second thanks to its parallel execution engine (Block-STM). This high throughput naturally results in low transaction costs for users on the network.

The Move is based on the Rust programming language, which is a well-known and supported programming language. MOVE was designed for the Diem blockchain by Facebook, which serves the function of implementing smart contracts and custom transactions. origins of Move largely arise from the known issues in the existing blockchain programming languages such as Solidity, which has security and verifiability issues. Any asset in Move can be represented by or stored within resources while scarcity is enforced by default since structs cannot be duplicated.

Aptos is founded by Aptos Labs and co-founded by Mo Shaikh and Avery Ching. Mo Shaikh, Avery Ching, and a few other team members worked together at Meta on the Diem blockchain project before. They founded Aptos Labs together to continue building on the technology they had originally developed for Diem. Austin (@austinvirts), the former head of marketing at Solana, is currently working as director of the ecosystem in Aptos Labs. The Aptos Team also has many experienced designers, analysts, engineers, and so on. Obviously, it is a professional team, with the ability to develop the Aptos very well.

How to define the speed of a blockchain? It depends on two aspects: transactions per second (TPS) and time to finality (TTF). For blockchains, transactions per second (TPS) refers to the number of transactions that a network is capable of processing each second.
Here is the equation of TPS:
TPS = (number of tx in a block)/(block time in seconds)
Finality is the assurance or guarantee that cryptocurrency transactions cannot be altered, reversed, or canceled after they are completed. The latency level of a blockchain will ultimately affect the chain's finality rate. For users, the definition of a blockchain’s speed is time to finality (TTF), the amount of time needed to fully confirm a transaction.
Let’s compare the TPS and TTF between some blockchains:

From these blockchains, Aptos has the shortest time to finality and a very high TPS. The TPS for Aptos can reach at least 130k, because of the highly efficient, multi-threaded, in-memory parallel execution engine. Aptos blockchain has sub-second finality, which means that a transaction will take less than 1 second to be fully confirmed. Such a fast speed can give users a better experience than other famous blockchains.
Although the mainnet of Aptos has not been launched, there are many projects that have joined the Aptos.


The Econia is a protocol that lets anyone in the world trade a digital asset with anyone else in the world, at whatever price they want. More specifically, Econia is a central limit order book (CLOB), a fundamental financial tool utilized by financial institutions like stock markets, except unlike the New York Stock Exchange or the NASDAQ, Econia is open-source and decentralized.
This version 1 minimum viable prototype (v1 MVP) introduces a key innovation for on-chain trading, Econia's atomic matching engine, which settles market orders with finality during the transaction in which they were placed.

The Martian wallet is a crypto wallet that can be used to manage digital assets and access decentralized applications on the Aptos blockchain. Martian wallet is currently available as a Chrome extension and soon will be available as an IOS app.
At its core, Martian wallet works by creating and managing private keys on behalf of its users. These keys can then be used within the Martian wallet to store funds and sign transactions.
To interact with web applications, the Martian wallet extension injects an Aptos object into the JavaScript context of every site the user visits. A given web app may then interact with Martian wallet, and ask for the user's permission to perform transactions, through this injected object.

The Liquidswap is the first AMM for Aptos - the most performant & reliable L1 built with Move VM. Liquidswap is a product developed by Pontem, which is a studio working toward global financial inclusion powered by blockchains. Pontem team is going to first build the next generation of Dapps with streamlined experiences enabled by Aptos and Move. Starting with the key foundational protocol of an AMM for correlated and uncorrelated pairs. This will enable liquidity and discoverability for protocol tokens in the Aptos ecosystem. Liquidswap is the uniswap on Aptos.

The Aptos Name Service is a smart contract that maps a name to an Aptos address. Claiming a name mints you a special NFT Token that gives you the sole power to edit the address of that name. That Token is composable and can be bought, sold, and traded as you see fit. It’s a decentralized, composable identity layer of Aptos. ANS is the ENS on Aptos.

The Topaz is an NFT marketplace built on the powerful Aptos blockchain, with a focus on safety and scalability. Topaz is the Opensea on Aptos.

The Vial is a pooled interest rate protocol that allows users to lend or borrow assets on Aptos. Interest rates are determined algorithmically based on pool utilization: the ratio of borrowed to supplied assets. Vial is the AAVE on Aptos.
