<hr>Hey friends. Welcome back to another biweekly dev update.We’ve spent the past two dev updates talking about our Multiple Multi-wallet update and the bug fixes associated with it. It’s a significant architectural change, and we’re glad to have received feedback that many of you find the extended flexibility of having multiple wallets useful.Of course, architectural and account model changes might be too low-level than most users care about, so this week, I think it’s worth zooming out a bit to talk about KryptoGO’s vision, and how our constant product updates, whether it be new features, upgrades of existing features, or even bug fixes, align with said vision.<hr><h4>Your Crypto Portfolio, as comprehensive as can&nbsp;be</h4>KryptoGO Wallet, starting from version 2.0.0, supports multiple wallets from multiple blockchains. Yes, it’s great and all, but let’s face the elephant in the room: It’s not enough.Since the beginning, one thing that KryptoGO has always wanted to do for our users was to make a comprehensive portfolio that made it easy for everyone to keep track and manage their on-chain assets, ideally for as many chains as needed. If you think about it, this is the very definition of a wallet. You look at your wallet, and you are able to see your assets.However, in the world of cryptocurrency, where new blockchains, tokens, DeFi investments, and NFTs pop up like bamboo shoots after a refreshing spring rain (that’s a real Chinese idiom), even meeting the bare minimum of a wallet is hard. That’s why a lot of wallets on the market either focus on supporting a single chain (e.g., an Ethereum wallet like Rainbow or Metamask), or they focus on supporting a single asset class (e.g., an NFT wallet like Floor).However, this kind of design philosophy poses problems for both crypto veterans and beginners alike. Veterans likely have assets across many chains, in many asset classes, which means they need more than one wallet in order to keep track of everything. If you think someone who carries ten physical wallets when they go shopping at Target is wack, then wait till you find out how many crypto wallets a crypto veteran at KryptoGO had before KryptoGO Wallet was released (hint: it’s more than 10).For crypto newbies, even without any assets, they face a problem immediately. Out of the hundreds of wallets on the market, which one do they choose? This problem is compounded when the user lacks the knowledge of blockchains and different on-chain asset classes. If a user doesn’t know that Bitcoin and Ethereum run on different chains, how are they to choose the wallet that is right for them?Therefore, the product team at KryptoGO believes that the multiple multi-wallet update only just fulfilled the fundamentals that any decent wallet should have. We’ve significantly lowered the barrier for entry. Crypto beginners can start using our wallet immediately and be assured that we support many mainstream blockchains. Our proprietary “phone number as account identity identification” model makes this even easier: Registration is super fast, and users do not need to memorize or even know what a private key is to start using our wallet. On the other hand, crypto veterans finally have a wallet that can effectively consolidate all their on-chain assets in one comprehensive portfolio. The multiple multi-wallet update provided a base on which to build new and exciting features, and now a single question lingers. What do we currently want to build?<hr><h4>Interact with the world as your Web 3.0 Identity, using KryptoGO&nbsp;Wallet</h4>Now that we’ve established this phone number 👉 multiple wallets 👉 comprehensive on-chain portfolio model, we want to make KryptoGO the go-to gateway whenever you want to connect a wallet of yours with some other service or utility, or more broadly, when you want to interact with the world, either online or offline, as your Web 3.0 identity. Our built-in DApp browser and Wallet Connect already help with this when you want to connect to any decentralized application. We’re currently focusing on offline interaction, so a big feature that we added this week focuses on NFT collections and NFT utility.Introducing…<h4>✈️ The Airdrop Center!&nbsp;✈️</h4><img src="https://cdn-images-1.medium.com/max/800/1*19T7scvA3aBn382CEjeHRA.png">The brand new ✈️ Airdrop&nbsp;Center✈️We’re betting that NFTs are going to be widely used in the future in all sorts of fun ways: coupons, membership cards, vouchers, admission tickets… you name it! So, we are introducing our in-app Airdrop Center, which works together with KryptoGO Dashboard for project teams and event creators to afford customizable utility to air-droppable NFTs!Here’s how it works: if you have any NFTs that received utility via KryptoGO (e.g., you might have an NFT that allows you to redeem a delicious free meal), you’ll see all these NFTs as well as their corresponding utility and redeemable rewards listed in the Airdrop Center, located on the Home Tab. You can see the details of the redeemable rewards, as well as any rewards that you have redeemed in the past.<img src="https://cdn-images-1.medium.com/max/800/1*QVqNlo5hof4zA5jlqJtX4A.png">The Airdrop Center lists all your NFT with utility (e.g. redeemable rewards)To redeem a reward, simply select the corresponding NFT, and choose Redeem Now. A QR code will be generated upon request. Have the event personnel (in the case of a free meal, maybe ask who’s responsible for NFT rewards at the restaurant?) open our in-app QR code scanner to scan your code. Once verification is complete and we made sure you are the owner of the NFT, you get your reward!<img src="https://cdn-images-1.medium.com/max/800/1*bKDITBWRuA1NI_-mrD65lQ.png">Redeeming a reward via QR&nbsp;codeWe hope to make it really easy to utilize on-chain assets in offline applications via our line of products, while giving users the smoothest experience as possible. We already have some collaborations in the works that we will reveal once the time is right, so stay tuned&nbsp;:)<hr><h4>Other new&nbsp;features</h4><ul><li>Payment Requests: You can now create a payment request that contains all the details of a payment (e.g., wallet address, token, amount) in a QR code. Send the QR code to whoever should pay you and they automatically get all the details they need.

Biweekly-20220928.png

This week, we zoom out to talk about our high-level vision and goals, and introduce our latest feature: The brand new Airdrop Center.

Biweekly Dev Update: September 28th, 2022

<blockquote>Not Your Keys, Not Your Coins. It’s That Simple.</blockquote>Never share your private key!When the private key isn’t yours, then the coin will no longer be yours. This is the most important concept before possessing crypto assets.<h1 style="margin-left:0cm;">What does “wallet” refer to?</h1>A wallet is what makes your private key (the password that gives you access to your cryptocurrency) secure and accessible.Unlike regular wallets that hold actual cash, we usually refer wallets in blockchain as “crypto wallets”. This wallet doesn’t store crypto assets directly, but rather access crypto assets that exist on the blockchain through a private key. The private key is what proves that you own the corresponding cryptocurrency and allows transactions to take place. If you lose your private key, you will not be able to access your funds, which is why it is so important to know how to keep your private key safe.Wallets allow us to send and receive cryptocurrency in a variety of forms, from hardware wallets like Ledger (which looks like a USB) to applications like KryptoGO Wallet, as follows:1 Paper: The secret key is written on a physical medium such as paper and stored in a secure location.2 Hardware (card, USB): The private key is stored in the hardware and connected to the computer and network only when sending or receiving cryptocurrency.3 Software: The private key is stored in an APP or browser plug-in.<blockquote>Deciding how to store encrypted assets is an important decision. Therefore, understanding the type of wallets is necessary for choosing which wallet works best for us. (these 3 forms above are usually non-custodial wallet presentations.)</blockquote><h1 style="margin-left:0cm;">Non-Custodial Wallet</h1>Using a non-custodial wallet means you are fully responsible for the private key, seed phrase, and funds. Because a third party trust is not needed in non-custodial wallets, you must protect your private key and find a strong password after creating a wallet.Most non-custodial wallets are browser-based or mobile apps like KryptoGO Wallet, a type of wallet also known as a hot wallet. On the other hand, there are cold wallets like the Ledger Nano, which are USB-like wallets that store your private keys offline.The downside to non-custodial wallets is that if you lose your seed phrase, forget your password, or somehow can't access your wallet, you won't be able to recover your wallet and therefore can't access your funds anymore.Non-custodial wallets play an indispensable role in enabling a completely decentralized world, but can be difficult for the newbies. Therefore, when using a non-custodial wallet, make sure you have multiple backups of your seed phrases and passwords, and that no one but yourself knows about them.<h1 style="margin-left:0cm;">Custodial Wallet</h1>If you have previously been to a centralized exchange, this means that you have used a custodian wallet. In this case, the centralized exchange acts as a custodian and holds your funds, private keys, and seed phrases. However, this also means that the exchange can do whatever it wants with the funds (you must choose your exchange carefully), and the concentration of funds is often vulnerable to hacking attacks. In addition, centralized exchanges also offer escrow services for institutional clients, such as Coinbase Custody.<h1 style="margin-left:0cm;">Conclusion</h1>Non-custodial wallets give you full responsibility for private keys, seed phrases, and funds. Custodial wallets, on the other hand, hold funds, private keys, and seed phrases for you.When you use a custodial wallet, you must trust the third party. Conversely, when using a non-custodial wallet, you must protect your key, seed phrase, and password.<img src="https://storage.googleapis.com/kryptogo-website.appspot.com/public/cms/noncustodial_vs_custodial_fdf081a0ad/noncustodial_vs_custodial_fdf081a0ad.png" alt="noncustodial vs custodial.png" srcset="https://storage.googleapis.com/kryptogo-website.appspot.com/public/cms/thumbnail_noncustodial_vs_custodial_fdf081a0ad/thumbnail_noncustodial_vs_custodial_fdf081a0ad.png 245w,https://storage.googleapis.com/kryptogo-website.appspot.com/public/cms/small_noncustodial_vs_custodial_fdf081a0ad/small_noncustodial_vs_custodial_fdf081a0ad.png 500w,https://storage.googleapis.com/kryptogo-website.appspot.com/public/cms/medium_noncustodial_vs_custodial_fdf081a0ad/medium_noncustodial_vs_custodial_fdf081a0ad.png 750w," sizes="100vw">The comparison table of non-custodial &amp; custodial wallet

Deciding how to store encrypted assets is an important decision. Therefore, understanding the type of wallets is necessary for choosing which wallet works best for us. 

<blockquote>Not Your Keys, Not Your Coins. It’s That Simple.</blockquote>永遠不要分享你的私鑰！當私鑰不是自己保管的，那麼幣就不是自己的，這是每個人要持有加密資產前最重要的觀念。<h1 style="margin-left:0px;">錢包指的是什麼？</h1>錢包讓您的私鑰（讓您訪問加密貨幣的密碼）安全且可訪問，與可以存放實際現金的普通錢包不同，區塊鏈中我們指的錢包通常為「加密錢包」，其實際上不直接存儲加密資產，而是透過私鑰訪問存在區塊鏈的加密資產。私鑰才能證明自己擁有對應的加密貨幣，並允許進行交易。丟了私鑰，將無法動用資金，這就是為什麼保管私鑰非常重要的原因。錢包讓我們可以發送和接收加密貨幣，有多種形式，從 Ledger（看起來像 USB）之類的硬體錢包到 KryptoGO Wallet 之類的應用程式，如下：<ol><li>紙：密鑰寫在紙等物理介質上，並存放在安全的地方。</li><li>硬體（卡片、USB）：私鑰儲存於硬體中，僅在收發加密貨幣時才連到電腦與網路。</li><li>軟體：私鑰儲存在 APP 或是瀏覽器插件中。</li></ol><blockquote>決定如何保存加密資產是一個大問題，這時候我們就必須決定使用了解錢包的類型，來選擇最適合我們的錢包（上述的這三種形式通常是非託管錢包的呈現形式。）。</blockquote><h1 style="margin-left:0px;">非託管錢包</h1>使用非託管錢包代表你要自行全面負責私鑰（Private Key）、種子短語（Seed Phrase）和資金。由於非託管錢包，不必信任第三方。創建錢包後，必須保護你的私鑰並找到一個強密碼才能使用非託管錢包。大多數非託管錢包是基於瀏覽器的或像 KryptoGO Wallet 這樣的手機 APP，這種類型的錢包也稱為熱錢包。另一方面，有像 Ledger Nano 這樣的冷錢包，它們是像 USB 一樣的錢包，可以離線存儲你的私鑰。非託管錢包的缺點是，如果你丟失了種子短語、忘記了密碼或以某種方式無法訪問您的錢包，你將無法恢復您的錢包，因此無法再動用資金。非託管錢包在實現完全去中心化的世界方面發揮著不可或缺的作用，但對於新手來說可能很難。使用託管錢包的時候，記得確保您有多個種子短語和密碼的備份，並且確保除了自己之外沒有人知道。<h1 style="margin-left:0px;">託管錢包</h1>如果之前使用過中心化交易所，則意味著您之前已經使用過了託管錢包。在這種情況下，中心化交易所作為託管人，保管了你的資金、私鑰、和種子短語。不過這也意味著交易所可以隨心所欲地動用這些資金（因此得慎選交易所），資金的集中通常也容易引來駭客的攻擊。此外，中心化交易所也為機構客戶提供託管服務，例如： Coinbase Custody。<h1 style="margin-left:0px;">結論</h1>非託管錢包讓你對私鑰、種子短語和資金承擔全部責任。另一方面，託管錢包為您保存資金、私鑰和種子短語。當您使用託管錢包時，您必須信任第三方。相反，在使用非託管錢包時，您必須保護您的密鑰、種子短語和密碼。<img class="image_resized" style="width:692px;" src="https://miro.medium.com/max/1400/1*9knZIQvospre8j11hW54Rw.png" alt="" loading="lazy">兩者的比較 &nbsp;

錢包的兩大類型：託管與非託管 — 沒有私鑰就不算真正擁有加密資產


Crypto Wallets: Custodial vs. Non-Custodial Wallets

The cover photo of The Economist in September: DeFi is like a rabbit hole, mysterious but full of opportunities to become rich, making people both curious and scared.<img src="https://storage.googleapis.com/kryptogo-website.appspot.com/public/cms/2_2b4453aaae/2_2b4453aaae.png" alt="圖片 2.png" srcset="https://storage.googleapis.com/kryptogo-website.appspot.com/public/cms/thumbnail_2_2b4453aaae/thumbnail_2_2b4453aaae.png 245w,https://storage.googleapis.com/kryptogo-website.appspot.com/public/cms/small_2_2b4453aaae/small_2_2b4453aaae.png 500w,https://storage.googleapis.com/kryptogo-website.appspot.com/public/cms/medium_2_2b4453aaae/medium_2_2b4453aaae.png 750w," sizes="100vw">Last year, the trading volume of decentralized exchanges has grown eight times more than centralized exchanges. What’s even more exciting is that according to the data on the chain, the number of DeFi users are only 2 % of Crypto users, and we can expect that there will still be a huge potential in the future.<img src="https://storage.googleapis.com/kryptogo-website.appspot.com/public/cms/3_89617e6819/3_89617e6819.png" alt="圖片 3.png" srcset="https://storage.googleapis.com/kryptogo-website.appspot.com/public/cms/thumbnail_3_89617e6819/thumbnail_3_89617e6819.png 245w,https://storage.googleapis.com/kryptogo-website.appspot.com/public/cms/small_3_89617e6819/small_3_89617e6819.png 500w,https://storage.googleapis.com/kryptogo-website.appspot.com/public/cms/medium_3_89617e6819/medium_3_89617e6819.png 750w," sizes="100vw">In June this year, the trading volume of Uniswap once surpassed Coinbase.The reason why there are only few DeFi users is that DeFi has a huge fragmentation problem due to many assets and public chains. This fragmentation will lead to many problems. For example, we can’t track the performance o DeFi effectively. If we display our single asset allocation on different wallets, we may get completely different performance and asset balances.&nbsp;Even though performance management is difficult, funds are still pouring in. Bitcoin has grown sixfold this year, and DeFi is a hot spot among hot spots, and we’ve seen a thousandfold growth in the past 18 months.&nbsp;DeFi has shown an irreversible trend: the era of Web 3 is coming.&nbsp;However, before DeFi becomes popular, the biggest challenge is to face regulatory problems. After all, anonymous finance is a hotbed of crime.<img src="https://storage.googleapis.com/kryptogo-website.appspot.com/public/cms/4_6906a8e85e/4_6906a8e85e.png" alt="圖片 4.png" srcset="https://storage.googleapis.com/kryptogo-website.appspot.com/public/cms/thumbnail_4_6906a8e85e/thumbnail_4_6906a8e85e.png 245w,https://storage.googleapis.com/kryptogo-website.appspot.com/public/cms/small_4_6906a8e85e/small_4_6906a8e85e.png 500w,https://storage.googleapis.com/kryptogo-website.appspot.com/public/cms/medium_4_6906a8e85e/medium_4_6906a8e85e.png 750w," sizes="100vw">Uniswap Labs were under investigation and “DEX” were on the US SEC’s radar.KryptoGO believes that compliance is the best way to bring out trust. As a manufacturer of Compliance as a Service, we allow our customers to focus on product development and leave the compliance headaches to us. In practice, all you need to do is submit a customer review request via API to our financial monitoring and investigation engine, and we will do the most complete due diligence from the aggregated data, identify features from these information, cross-check out non-compliant information, and automatically generate the risk assessment report.

The Buy-side can easily find safe and trustworthy investment targets through the APP without any cryptocurrency basics; Sell-side can efficiently handle asset custody, investment subscription &amp; redemption, KYC/AML, automatic reconciliation, NAV calculation, compliance/regulatory reporting, and performance charts through our management backend.

Our wallet focuses on the investment in DeFi to help the seller quickly accept customers. We help the seller painlessly manage any assets, all you need to do is download our wallet and we will handle these things for you.Many people ask, “Why do we need to make a wallet now when so many exchange wallets are working so sell now?” Exchange wallets do not directly participate in defi, and most of the performance is paid to the platform. There may be dozens of wallets on your phone, but none of them can meet the demand for simple DeFi investment.

為什麼我們要開發錢包：KryptoGO Wallet？

Why did we choose to develop KryptoGO wallet?

There are countless cryptocurrency wallets, and the key difference between them is how the private key is kept. This article focuses on the private key management mechanism and technology used in decentralized wallets like KryptoGO Wallet.<h1 style="margin-left:0cm;">Non-Deterministic Wallets</h1>Generate a random number string as the private key. (by cryptographically secure pseudo-random number generator) The public key has nothing to do with the private key, but when there are multiple private keys, they must be backed up, exported, and imported one by one, which is extremely cumbersome.In practice, this type of wallet is relatively rare.<h1 style="margin-left:0cm;">Hierarchical Deterministic Wallets (HD Wallet)</h1>The opposite concept of non-deterministic wallet. The HD wallet derives multiple public and private key pairs from the original seed phrase, so it only requires easily written seed phrases when backing up and importing the wallet. The concept was proposed by BIP32 (Bitcoin Improvement Proposals), BIP39 solves the problem of the difficulty to transcribe and memorize seed phrases, and BIP44 standardizes the path specification of each coin to reach industry consensus.The combination of BIP32, BIP39, and BIP44 is the current industry mainstream decentralized hierarchical wallet approach. This feature is suitable for collection services, such as store collection, creating a public key for each user to receive payments, and also allowing users to give other users airdrops, etc.<h2 style="margin-left:0cm;">BIP39: Making the seed phrase readable</h2>The main description of seed phrase code and the implementation of seed phrase. It consists of two parts:<ol style="list-style-type:decimal;"><li>Generate a seed phrase and convert it into a binary seed.</li><li>Seeds can later be used to generate deterministic wallets using BIP-032 or similar methods.</li></ol>Seed phrases are more friendly for human compared to processing the original binary or hexadecimal numbers of the wallet seeds. It can be written down or even be memorized by people with good memory. BIP39 generates numbers by transcoding irregular strings of numbers that are difficult to remember, splitting them, and mapping them in a single word list to generate seed phrases that can be read by humans to transfer computer-generated randomness.<h2 style="margin-left:0cm;">BIP32: The Foundational Standard for Hierarchical wallets</h2>Wallets can be partially or fully shared with other systems, with every system is able to send and receive independently. The purpose of this specification is to set a hierarchical wallet standard that can be exchanged between non-customers. Any pair of private keys can be derived through a common seed, and the private key derivation uses an irreversible algorithm that can only be derived from higher levels to lower levels. HD wallet can generate a large number of public keys using elliptic curve cryptography without the need for private keys.<img src="https://storage.googleapis.com/kryptogo-website.appspot.com/public/cms/0_Re2k73x_P9bc_Q_Xm6_K_e59c148df2/0_Re2k73x_P9bc_Q_Xm6_K_e59c148df2.png" alt="0*Re2k73xP9bcQXm6K.png" srcset="https://storage.googleapis.com/kryptogo-website.appspot.com/public/cms/thumbnail_0_Re2k73x_P9bc_Q_Xm6_K_e59c148df2/thumbnail_0_Re2k73x_P9bc_Q_Xm6_K_e59c148df2.png 245w,https://storage.googleapis.com/kryptogo-website.appspot.com/public/cms/small_0_Re2k73x_P9bc_Q_Xm6_K_e59c148df2/small_0_Re2k73x_P9bc_Q_Xm6_K_e59c148df2.png 500w,https://storage.googleapis.com/kryptogo-website.appspot.com/public/cms/medium_0_Re2k73x_P9bc_Q_Xm6_K_e59c148df2/medium_0_Re2k73x_P9bc_Q_Xm6_K_e59c148df2.png 750w," sizes="100vw"><a href="https://github.com/bitcoin/bips/blob/master/bip-0032.mediawiki">https://github.com/bitcoin/bips/blob/master/bip-0032.mediawiki</a><h2 style="margin-left:0cm;">BIP44: Indexing Method for Defining Derived Addresses</h2>The secret key derived through this hierarchy (tree structure) is usually expressed by the route, with slash (/) between each level, and the start of the private key derived from the primary private key is prefixed with an “m”.m / purpose'/ coin_type'/ account'/ change / address_index<ol style="list-style-type:decimal;"><li>purpose: BIP number, “44” for BIP44</li><li>coin_type: coin type, 60 for Ethereum</li><li>account: index of the account, starting from 0</li><li>change: 0 for external chains, 1 for internal chains</li><li>address_index: address index, starting from 0</li></ol><h1 style="margin-left:0cm;">External Wallet Address Generation Process</h1>Take the following seed phrases for example, the process of generating from seed phrases to the final wallet address that users see is as follows:&nbsp;rose rocket invest real refuse margin festival danger anger border idle brown<img src="https://storage.googleapis.com/kryptogo-website.appspot.com/public/cms/1_Z1rs_RK_Ug_D_mvt_K_Ltb_9_Kw_393311f975/1_Z1rs_RK_Ug_D_mvt_K_Ltb_9_Kw_393311f975.png" alt="1*Z1rsRKUgD_mvtK_Ltb-9Kw.png" srcset="https://storage.googleapis.com/kryptogo-website.appspot.com/public/cms/thumbnail_1_Z1rs_RK_Ug_D_mvt_K_Ltb_9_Kw_393311f975/thumbnail_1_Z1rs_RK_Ug_D_mvt_K_Ltb_9_Kw_393311f975.png 245w,https://storage.googleapis.com/kryptogo-website.appspot.com/public/cms/small_1_Z1rs_RK_Ug_D_mvt_K_Ltb_9_Kw_393311f975/small_1_Z1rs_RK_Ug_D_mvt_K_Ltb_9_Kw_393311f975.png 500w,https://storage.googleapis.com/kryptogo-website.appspot.com/public/cms/medium_1_Z1rs_RK_Ug_D_mvt_K_Ltb_9_Kw_393311f975/medium_1_Z1rs_RK_Ug_D_mvt_K_Ltb_9_Kw_393311f975.png 750w,https://storage.googleapis.com/kryptogo-website.appspot.com/public/cms/large_1_Z1rs_RK_Ug_D_mvt_K_Ltb_9_Kw_393311f975/large_1_Z1rs_RK_Ug_D_mvt_K_Ltb_9_Kw_393311f975.png 1000w," sizes="100vw">From seed phrases to wallet addressThe efficacy test could be done by<a href="https://iancoleman.io/bip39/#english"> Mnemonic Code Converter</a>:<img src="https://storage.googleapis.com/kryptogo-website.appspot.com/public/cms/1_ceh_Z5jx7y_M_Uv_v_Lo_Z4r_Jg_07b171628d/1_ceh_Z5jx7y_M_Uv_v_Lo_Z4r_Jg_07b171628d.png" alt="1*cehZ5jx7yMUv_-vLoZ4rJg.png" srcset="https://storage.googleapis.com/kryptogo-website.appspot.com/public/cms/thumbnail_1_ceh_Z5jx7y_M_Uv_v_Lo_Z4r_Jg_07b171628d/thumbnail_1_ceh_Z5jx7y_M_Uv_v_Lo_Z4r_Jg_07b171628d.png 245w,https://storage.googleapis.com/kryptogo-website.appspot.com/public/cms/small_1_ceh_Z5jx7y_M_Uv_v_Lo_Z4r_Jg_07b171628d/small_1_ceh_Z5jx7y_M_Uv_v_Lo_Z4r_Jg_07b171628d.png 500w,https://storage.googleapis.com/kryptogo-website.appspot.com/public/cms/medium_1_ceh_Z5jx7y_M_Uv_v_Lo_Z4r_Jg_07b171628d/medium_1_ceh_Z5jx7y_M_Uv_v_Lo_Z4r_Jg_07b171628d.png 750w,https://storage.googleapis.com/kryptogo-website.appspot.com/public/cms/large_1_ceh_Z5jx7y_M_Uv_v_Lo_Z4r_Jg_07b171628d/large_1_ceh_Z5jx7y_M_Uv_v_Lo_Z4r_Jg_07b171628d.png 1000w," sizes="100vw">Account Model for KryptoGO WalletOur unique account model is a one-to-one matching of phone numbers and seed phrases, and derives multiple chains of wallet addresses.

加密貨幣錢包多不勝數，之間的關鍵差異就在於私鑰的保管方式。這篇文章主要介紹 KryptoGO Wallet 這類型去中心化錢包所使用到的私鑰管理機制與技術。<h1 style="margin-left:0px;">非確定性錢包（Non-Deterministic Wallets）</h1>隨機生成一個數字串作為私鑰，可以使用密碼學安全的偽隨機數生成器，公鑰與私鑰毫無關係，缺點當有多個私鑰，必須逐個備份，導出，導入，極其麻煩。實務上這類型的錢包比較少見。<h1 style="margin-left:0px;">階層式確定性錢包（Hierachical Deterministic Wallets）</h1>俗稱 HD 錢包，與非確定性錢包相反，由最原始的 Seed Phrase 推導出多個公私鑰對，在備份導入錢包時候就只需要助記詞方便抄寫。HD 錢包可以在不需要私鑰情況下運用橢圓曲線算法生成大量公鑰。概念是由 BIP32（Bitcoin Improvement Proposals）提出，BIP39 解決助記詞難以抄寫記憶問題，BIP44 規範各個幣種路徑規範達成業界共識。結合 BIP32, BIP39, 以及 BIP44 就是目前業界主流的去中心化分層錢包的做法。這個特性適合收款服務，比如商店收款，為每個用戶創建一個收款公鑰匙，也可以用戶給用戶空投等。<h2 style="margin-left:0px;">BIP39：讓助記詞具備可讀性</h2>主要描述助記詞代碼，助記詞句子的實現，包括兩部分<ol style="list-style-type:decimal;"><li>生成助記詞，將其轉化為 2 進制種子</li><li>種子可以稍後用於使用 BIP-0032 或類似方法生成確定性錢包。</li></ol>與處理錢包種子原始二進制或十六進制數字相比助記符對於人類交互是更優越的。可以寫在紙上，記性好的還可以背下來。BIP39 將一些列難以記住的無規則的數字串通過轉碼拆分後生成數字，在於單詞表進行映射生成助記詞，通過人類可讀轉錄傳輸計算機生成的隨機性，<h2 style="margin-left:0px;">BIP32：階層式錢包的基礎標準</h2>錢包可以部分或全部與其它系統共享，每個系統都能獨立收發。這個規范的目的是設定一個分層錢包標准，能在不通客戶之間交換。通過一個共同的種子可以導出任意對私鑰，私鑰推導採用不可逆算法，只可以由高層級推導低層級，HD 錢包可以在不需要私鑰情況下運用橢圓曲線算法生成大量公鑰。<img
