Bizblocks has made up line-up by developing Kaiser Watch and Wallet bank that improved portability, security and compatibility starting with Kaiser Wallet, hardware wallet has EAL6+ security authentication of CC* top class (Joint Assessment Criteria). At the center of the project is Aiser chain with the hardware security technology of Bizblocks and DApp chain, application of API of Aiserchain guarantees easy of DApp development and safety. Also, Aiserchain integrated Kaiser DEX, decentralized exchange of Kaiser into relevant blockchain and activated all coin transactions including Kaiser coin.
In addition, DEX works with Bizblocks' platform business and expands services in order to use actually and conveniently through payment system (POS and app payment). Patent-pending BSM of Aiserchain enhances the security in private chain and WalletBank, Kaiser security system, which is applicable to each platform can store assets safely against hacking. It establishes not only security but also circumstances possible to authenticate at fast speed so that increases service satisfaction of actual users but also is easy to develop business with wide applicable usage using API/SDK.
Kaiser Hardware Security System
There have been the series of record-setting hacks by new kinds of financial crime in crypto exchange and the damage of hacking is as large as 500 billion won. The coins that were hacked were stored in an online wallet (Hot Wallet). Online Wallet is a storage that is connected with the network. Users use the online wallet because the crypto exchange is reasonable, easy to manage and is capable of real-time money transfers.
However, there is a disadvantage that the online wallet stores personal assets online where it is vulnerable to hackers. Therefore, if one‟s crypto currency is stored in the Crypto exchange, it allows anybody to look through one‟s wallet.
Cold Wallet was born as a solution to online wallet‟s downfall. Cold Wallet is offline, where the private key is stored outside of the network. In other words, cold wallet is stored like a regular credit card or real money and it lessens the dangers of being hacked since it is not connected to the internet.
Users are relatively low, even though the cold wallet has better security, because of the inconvenience in using this wallet. Bizblock‟s Kaiser Wallet is protected from various kinds of external hacking such as Didos, Phishing, and Farming, and it represents the next generation of hardware wallet because it is the solution to current hard wallet issues.
IC Chip Card (Secure Element)
IC Chip Card is an electronic card that has the IC Chip attached and looks just like a regular credit card. The IC Chip on the card has 8 Byte or 32 Byte MPU, COS and EEPROM for secure storage. In other words, there is a small computer inside the card. The current magnetic card has security issues like key damage and card infringement. On the other hand, IC Chip Card is the next card of the century because it‟s impossible to copy and the shape of the card is makes it hard to damage.
The IC Chip can be divided into 4 kinds: Contact, Contactless, Hybrid and Combi (Combination). Kaiser wallet uses the combination card. The Combination Card interacts with both the contact and the contactless. If the combination card is used, one is able to use the shared application (Chip operating system, same key and password) and bring the joint benefits and reap the benefits of both contact and contactless cards.
Kaiser wallet uses the contactless communication NFC to share data with the smartphone. However, NFC is not only used. If contacted with a contact leader, this could also be used to communicate.
IC Chip that was used in Kaiser Wallet is the top grade, CC - EAL6+ (Semiformally Verified Design and Tested) certified.
EAL: Common Criteria Security Evaluation, International Standard
IC Chip Physical Architecture
The IC Chip consists of an OS(Operating System) read by the ROM(Read Only Memory)an EEPROM(Electrically Erasable Programmable Read-Only Memory) where the developer can load the program with electrical stimulation, a RAM(Random Access Memory) loaded when operated, an I/O System(Input / Output System) controlling the input and output of the chip and finally a CPU(Central Processing Unit)controlling everything. When the electrical power is supplied to the tag, the OS on the ROM gets loaded on to the RAM and starts to boot. When the booting is complete, the program on the EEPROM is loaded on to the Ram to fulfill the purpose of the program. This process can differ depending on the size, specifications and composition of the hardware.
IC Chip Logical Architecture
A Card OS is an ultra light OS. It creates environments for the functions stated in the IC Chip Card Virtual-Machine(IC Chip Card VM) to be worked normally, controls the input and output and other orders. Depending on the specifications of the card the kinds of support vary. The IC Chip Card VM interprets the byte code and runs it allowing the IC Chip Card Applications to function. The IC Chip Card Framework and API provide the environment and tools for the developer to create the Applet. The Applet is an IC Chip Card application program. By compiling applicable codes and converting them to byte codes, they are then fulfilled by VM. There are more than one applets, allowing not one but many functions to be used integrally.
Users require FIDO(Fast Identity Online) server of user verification through Kaiser App. without additional device or physical wallet in any circumstances. FIDO verifies users‟ identity through biometric information such as fingerprint and iris. And user requires electronic signature through API interworking, generates HD keys at Secure Execution Engine BSM(Back-hardware Secure Module) where is authenticated circumstances and electronic signature is done through relevant keys. At that time, core keys are generated within SEE are never exposed to outside. At that time, core keys are generated and proceeded within BSM and which are never exposed to outside. Electronic signed data consists of relevant blockchain transactions and record all the data in the blockchain through API server. The blockchain receives transactions from API server and validates them. User.
Kaiser WalletBank has been upgraded the portability, while still maintaining security by proceeding electronic signature only within the Kaiser Wallet‟s Hardware SE (Secure Element). Kaiser Wallet bank has improved convenience because it is not used as physical device like card. In other words, it is economical by reducing unnecessary cost and time (global shipping) because there is no need to deliver directly to users who don‟t need to carry. It also lessens the possibility of loss and damage. In case of Kaiser Wallet bank, electronic signing process is complete inside BSM(Back-hardware Secure Module) when signature is required. From this, it shows higher security because it uses key only inside equipment not coming outside. BSM itself is also a verified product and the system of Kaiser Wallet bank is composed in authenticated security circumstances. The compatibility is also additionally upgraded. Existing hardware wallet needs to connect cable or device supporting BLE, NFC communication depending on the device you use. The WalletBank is accessible using only an app, without any extra device. Finally, BSM is server-type equipment, supports much more algorithm, enables to establish circumstances supporting all the coins and is extremely improved in the speed of processing.
Lastly, various Dapp are able to be implemented in Kaiser WalletBank. Bitcoin or Ethereum users a simple and secure WalletBank app, and the users flow into the platform that is connected to the WalletBank secondarily. With Kaiser DApp tool, developers can easily implement a platform so they are able to establish their desired business model and coin policy.
Hardware Wallet SDK, API
Kaiser security system project is not limited to B2C, but provides security services to companies. It provides interface-interworking with customer‟s own app. by using Kaiser API as well as Kaiser Wallet and App. service itself. Kaiser SDK, API helps minimalizing development procedures and provides interworking with customers‟ App/platform. In other words, it enables to develop customizing program for different development purpose. It also provides highly compatible SDK for the program‟s operating system and to widen the operating circumstances.
Aiserchain & DApp
Aiserchain supports user-to-chain connections in Front Area. User authentication is a main factor in the front area. The core key of user authentication performs all of the operations itself from the Secure Element of IC Chip that enable data to be stored and sent. User authentication can be done through devices that support Bluetooth and NFC communication (Wallet, Watch), and if the user don‟t want to carry the device, user authentication can be obtained through a separate biometric device (iris, fingerprint) using Kaiser WalletBank. Walletbank's key management and signature are processed in the Security Execution Engine to support both security and convenience. It executes front area process with user authentication in Kaiser Wallet, Watch, and WalletBank and enters Aiserchain through App Development SDK.
In a block-chain platform, integrity is very important because it is a measure of the level of security. There must be a lot of participants in order to have integrity. However, if the number of nodes is large, the number of blocks accumulated in the main chain also increases, which causes the transaction processing speed to be slowed down.
Aiserchain has constructed a hybrid blockchain to overcome these disadvantages. The primary processing takes place in a private blockchain involving only a few authorized nodes, which is based on the etherium quorum. Because fast confirm speed is crucial in the payment and P2P trading functions, Aiserchain preferentially supports this environment through a private blockchain. Private blockchain‟s processing speed TPS (Transaction Per Second) is 300,000. In the private blockchain, the DApp chain is run separately by side chain to help speed up processing and solve problems easily when unstable DApp occurs.
The hybrid blockchain is primarily processed in the private blockchain and secures integrity and reliability in the public blockchain secondarily. Aiserchain's public chain is risk-based, and through a hybrid blockchain that combines the two blockchains, each chain can focus on their respective advantages.
Even though ERC20-based coins can be easily integrated into exchanges and other company‟ s wallets via smart contracts in the Etherium blockchain network, the disadvantages of this system are the high fees (gas), The traffic symptoms in the chain, and thus the low block processing speed. In order to overcome such a circumstance, the third generation cryptocurrency attempts to build a scalable blockchain solution to replace it. But it is also difficult to overcome the security problems of blockchain ecosystems and hard to satisfy both users and developers because of the limit of Scalability.
Enhanced security through BSM
Hacking in the blockchain occurs by analyzing the patterns and weaknesses of the algorithm and attacking or attacking the encryption key. Aiserchain introduces BSM to prevent such risks. BSM, a hardware security module, is a solution that combines a hybrid blockchain and an enterprise type hardware key storage system. It stores core keys in BSM and performsan operation process on the electronic signature and the key itself. When authentication and data requests are made in the private blockchain, the operation process and electronic signatures are processed in the BSM, encrypted and transmitted to the private blockchain. Then, the private blockchain passes the received signature value to the public blockchain. Therefore, all Aiserchain data transmission/ reception contents are transmitted in encrypted forms and the attacker's access to the core key can be blocked at the source..
In general, a multi-signature method is used to overcome the security problem of the private blockchain. A multi-signature is an authorization method that a co- signer is created at the transaction and cannot be transmitted with one private key. It can be sent when approved by a co-signer. The security aspect is enhanced compared to a case where a transaction is performed with only one private key signature. However, there is a disadvantage that the waiting time for the approval of the co-signer is prolonged, and the signature process is ignored because the co-signer is not approved within a limited time.
However, the MS (Multi & Synchro) signature provided by Kaiser BSM is a method in which digital signatures occur simultaneously with multiple signatures. In the contract on the chain, the private key of the user and the private key stored in the BSM are co-signers. At this time, when the private key of the individual is approved at the transaction, the BSM processes the approval automatically. So it can be processed quickly and also any process is ignored due to waiting time. As a result, Aiserchain is able to transmit and receive data securely between private blockchain and public blockchain through BSM and MS signature, thereby improving security and speeding up the process by eliminating waiting time delay.
DApp chain & DApp
Kaiser's DApp chain ensures stability and the ease of DApp development as it utilizes the Aiserchain's API. Aiserchain. DApp chain works together with hybrid chain forming the Aiser platform. The Aiser platform uses two kinds of tokens: Kaiser Coin (KISC) and DApp token. DApp tokens can be traded with KISC and it forms a KISC-based Aiser DApp platform.
The most important thing in a blockchain ecosystem is practical use. Kaiser provides DApp development environment called 'DApp Chain' for actual use and for the vitalization of the platform. The DApp chain is side-chain format that developers can construct its own chain through making use of Kaiser's Aiserchain API / SDK. It provides a DApp development tool called Aiser-CLI (Command Line Interface) which supports easy development and the realization of activating the platform.
As mentioned, Aiser CLI allows DApp developers to build their own DApp environment. The Aiser CLI has features such as Init, Compile, Migrate, Debug, Discard and so on. Developers can use these functions to speed up the process of development, and thereby it is possible to secure the nuber of users as the use of Kaiser DApp chain is spread widely. By using the migration of Aiser CLI, the developer can shift the previously developed binaries into the DApp chain and this DApp chain handles coin and token related matters. In addition, DApp chain has Aiserchain's fast processing speed with Aiserchain's API and it gains the security with backed by BSM. Therefore, if you install a DApp in the Kaiser DApp chain, you can develop it more safely and easily than other DApps.
Moreover, Kaiser provides a graphical DApp development tools (graphical tool) for non-specialists to widen the range of use so that more developers come to Aiserplatform and they can be built the ecosystem. Graphic tools make Java Scripts into functions using graphical UI. Using this function, it makes easier for developers to develop DApp, and due to the wide range of DApps that are developed and loaded, the diversity of the Aiser platform is expanded.
In Kaiser DApp chain, KISC is used as a service fee. When DApp creates a transaction, a corresponding fee is generated (eg, GAS of ETH). This fee is used as a fixed amount of KISC. The fee is paid by the DApp developer, not the user who generated the transaction. This may seem to be a disadvantage to DApp developers, but it is not. This is because except the standard KISC fees generated, additional fees are set by the developer himself. So, the remainder fee can be the developer's profits depending on the setting. In other words, unlike the ERC20 platform, which does not benefit the developer even if a lot of transactions occur, the developers of Kaiser DApp platform can take some of the commission according to the amount of DApp transaction. As a result, DApp developers can generate additional profits, such as transaction fees. And this revenue models on the platform can lead to the flow of DApp developers.
Vitalization plan for DApp ecosystem
The most important thing in the block chain platform industry is the Vitalization of DApp. Therefore, Kaiser has set up various plans to revitalize the DApp ecosystem.
First, the most important issue in the recent blockchain market is actual use. As Kaiser's ecosystem builds a platform supporting for real-world and hardware assets, Kaiser's DApp is also loaded with real-world-based platforms. This real-world-based DApp is called MVP (Minimum Visible Product) DApp. There are several judging criteria for entry into Kaiser's DApp ecosystem. However, the most crucial and difficult gateway is the presence of MVPs. If there is a real thing, you can know the company's sales and net profit. So, in a real-life project, it is possible to take reasonable judgment and to calculate the token value thereby formming a reasonable price accordingly. Therefore, Kaiser's DApp ecosystem is able to build a reliable platform based on actual use.
The second is token analyst. As the market for block chain grows, the inflow to this industry has been increased both in experts and general investors. However, it is obvious that non-professional investors are lacking in expertise such as investment information, and market analysis capabilities. Accordingly, Kaiser supports the token analyst system to allow investors to invest in DApp tokens based on more reliable and credible information. Token analysts produce their portfolio and investment wrap such as general token analysis, market outlook and chart analysis of DApp. Wrap is a term used by securities firms. If analysts think something is worth to invest, they make them as a bundle and put it out as one investment product. It provides investors with useful information such as detailed investment description of the constituent stocks, reasonable rationale for the investment, and appropriate investment allocation. Analysts' investment-related information is partly paid services, which are priced at a reasonable price.
Third, the DApp development company on the Kaiser platform can invest directly in Kaiser DEX through IEO. IEO is an abbreviation of Initiative Exchange Offering and it refers to a project which invests directly in the exchange market. Since Kaiser owns its own DEX, the DApp project team is able to fund the IEO through Kaiser DEX and it is able to support the installation in the Kaiser DApp ecosystem as well. Kaiser also invests in the DApp platform through its own R&D of Dap to achieve the completeness and the scalability of the Kaiser DApp platform.

The mining of Kaiser works on Cloud server and it‟s a binary method consisting of miners + master nodes. The total supply of KISC is 4 billion and the sales volume is 2.8 billion (70% of the total supply), and the issued company‟s holding amount is 1.2 billion(30% of the total supply).
Kaiser uses the DPOI(Delegated Proof of Importance) consensus algorithm, and evaluates the level of contribution and coins are allocated depending on the contribution level to the liquidity and the transaction of the coins. DPOI is a democracy style consensus format that only the top activated 101delegated stakeholders actively maintain ecosystem, secure security and their shares are delegated. It just enables every node (miner) to mine through the continuous mining programs that the company provides in order to sustain nodes aside from mining by master nodes. Through this, we build the trusted network ecosystem of public blockchain.
The existing mining methods including POW, POS, DPOS only allows the individual to prove one‟s share directly, takes a lot of electricity and time and also vulnerable in the attack of 51% dominating hash power. Whereas DPOI algorithm of KISC has improved the existing inefficient methods in every aspect such as electricity use, time consuming and mining speed etc.. DPOI policy of KISC pursues democracy and high efficiency. A miner delegates its stake to a master node in security for coins, and the master node having high mining performance ability is mandated to mine instead. Kaiser, this kind of a user-centered decentralized service allows more chances of reward to return to the nodes who contribute to the chain facilitation, and it will lead to persistent activities.
Once mining starts, the miner give the master node coins as a guarantee and the nodes receive rewards as much as the ratio of coins that were taken as security out of the 50% of the completed mine coins. In this structure, as miners do not need to work the server directly, even though a regular node is not directly involved in mining, efficient mining through a master node can be done and it allows master nodes to do economic activities by mining bigger volume of coins with the delegated coins to them in a short period of time.
A master node means the top nodes of many nodes and the mining method of a master node has the strength that its maintenance and management is available at low cost all the time. For the smooth transaction between users, a master node performs a specific service. Since it takes a lot of time and cost to perform the service, a certain amount of incentive is provided to them for the cost.
The selection standards of a master node are to put together at least, more than 5,000 KISCs, Kaiser Wallet possession, the holding period of coins, the amount of coins they hold, average transaction times, the number of block generation etc., the level of contribution to the network inside Aiserchain network, and finally 101 master modes are elected among the candidates with high average scores by real-time voting of regular nodes. Every node has a right to vote, then the top 101 nodes who receive the most votes are delegated as master nodes.(Voting doesn‟t guarantee that the delegated you voted for becomes a master node.) Also the selected master nodes come to mine on Cloud Server according to their mining systems and they receive 40% of the mining amount as their commission. Master nodes don‟t need a specific mining hardware, maintenance fee, time and labor consuming etc. perform reasonable and economic ways of mining. In addition, each mined amount is indicated on the wallet linked APP and WEB. Then it makes it easy to figure out the mining performance ability of each master node, and helps regular nodes to make reasonable choices for their stake delegation. A master node not only receives 40% commission in compensation for mining, but also is provided with the additional coin reward according to the average holding amount of the coin within a certain period of time during the airdrop.
- Kaiser receives 10% fee by permitting master nodes to mine on Cloud server including the implementation and management of the mining environment. Also, if a node wants to delegate mining to the company, the company publishes it and performs the mining directly on behalf of the node.
Kaiser DEX is designed to eliminate the risk of hacking into centralized transactions through data public materials, which is the strength of blockchain and to apply advanced technologies in various cryptocurrencies trading. As Kaiser DEX sloves the hacking problem of centralized exchange by strengthening security through Kaiser Wallet bank, it provides good services like complementing the delay in making a contract at the existing decentralized exchange by using hybrid Aiser chain.
Cryptocurrencies have different values. The exchange of different values is established through main currency. Kaiser supports value exchange of users and transactions between users rather than service providers. First, safe asset storage shall be realized through Kaiser Wallet (Hardware Wallet). As a way to guarantee secure transactions of Kaiser Wallet, the value is established in the Aiser net with Kaiser App. and several cryptocurrencies.
The Aiser chain has two advantages in terms of security. One is use of hardware wallet, Kaiser Wallet and the other is to work in the Security Zone with the dualization inside BSM or security credibility. In particular, Kaiser security system is called Kaiser Wallet bank, which enables assets to be kept safe. Kaiser coin measures the ratio as a standard at the center of exchange of many coins. It also establishes the safety step through blockchain authentication information and makes information public with Aiser chain based Lisk
Aiser chain was designed in hybrid form in combination with private chain as a complement to the delay of public chain authentication. By connecting with private chain and improving the speed, it meets the needs of users. It is differential from centralized private chain and composes services with much more free smart contract considering advantages with boundaries of wallet bank system and public chain.
First, it is proceeded distributed transaction information is proceeded as authentication block value between individuals. Unlike central processing, it has the information of individual transaction in the grouped network as blocks, makes public to keep safe and store decentralized. Therefore, it has all authenticated procedures until users transfer information of Aiser chain to public chain. The transactions are completed after they are transferred to public blockchain passing through the calculating desk.
