① What is the super ledger in the blockchain?

The ledger (Ledger) has a certain format and consists of several account pages. It is based on accounting vouchers and controls all economic businesses. The book that carries out sequential classification records is what we usually call an account book. Blockchain represents a unique data recording format. Blockchain is "block + chain". The so-called block means data block. Each block is connected by a certain mark to form a chain. .

Hyperledger

Hyperledger (Chinese name is Hyperledger, collectively referred to as Hyperledger) is an initiative launched by the Linux Foundation in 2015 to promote blockchain digital technology and An open source project for transaction verification. Hyperledger's goal is to allow members to work together to build an open platform to meet the needs of various users from many different industries, while greatly simplifying business processes. The founding members of Hyperledge include major companies such as IBM, Intel, and Cisco. As of the completion of this book, more than 183 institutions and companies have joined Hyperledge, and they are growing rapidly.

When the Hyperledger project was established, the Linux Foundation had received several different code bases, including the IBM code base (to a certain extent inspired by Ethereum), and the DAH (Bits of Proof) Bitcoin code base. and the Sockstream codebase (an extension of the Bitcoin codebase). In addition, there are codes contributed by DigitalAsset and Ripple. With the development of the industry, a single project can no longer meet business needs, so Hyperledger has gradually developed from a single project into a project team. At present, Hyperedger is no longer a specific technology, but represents a collection of blockchain technology frameworks. As of now, the Hyperledger project team contains a total of 9 formal projects and more than 50 related modules of these formal projects.

The Xueshuo Innovation Blockchain Technology Workstation under Lianqiao Education Online is the only "blockchain technology" approved by the "Smart Learning Workshop 2020- Xueshuo Innovation Workstation" carried out by the School Planning and Construction Development Center of the Ministry of Education of China. Professional” pilot workstation. The professional base is based on providing students with diversified growth paths, promoting the reform of the training model integrating professional degree research, production, and research, and building an applied and compound talent training system.

② What exactly is blockchain? Decrypt the concept of blockchain

③ What is blockchain and what are the applications of blockchain in life? Blockchain is a new application model of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. (The consensus mechanism is a mathematical algorithm that establishes trust and obtains rights and interests between different nodes in the blockchain system). BlockchainTechnology is a technology that uses a decentralized consensus mechanism to maintain a complete, distributed, and non-tamperable ledger database. It allows participants in the blockchain to achieve a unified process without establishing a trust relationship. ledger system. In layman's terms, the blockchain is a general ledger that contains all historical transactions, and each block contains several transaction records. If the blockchain is a ledger, then a block is one page of the ledger. Details of transactions are recorded on a public ledger that can be seen by anyone on the network.

A block is a collection of many transaction data, which is marked with a time stamp and a unique mark of the previous block. Valid blocks will be appended to the main blockchain after they are unanimously recognized by the entire network. Blockchain is a data structure in which blocks containing transaction information are linked in order from back to front. The most well-known application of blockchain technology in the virtual currency market is Bitcoin.

At 3:00 pm on September 4, 2017, the People's Bank of China and seven other departments jointly issued the "Announcement on Preventing Token Issuance Financing Risks", defining ICO as "an illegal public offering without approval" Financing behavior,” the regulatory authorities also stated that all types of token issuance and financing activities should be stopped immediately, and organizations and individuals that have completed token issuance and financing should make arrangements such as withdrawal. A deputy dean said, “It is normal for the rapid development of ICO to attract the attention of regulators. From the perspective of traditional law, ICO is suspected of crowdfunding and raising capital, and it is very risky to allow development without supervision. A large number of unpromising projects are even deceptive in themselves, which not only makes investors bear huge risks, but also makes real blockchain entrepreneurial teams complain a lot, which actually has the adverse consequences of bad coins driving out good coins. A large number of retail investors and even 'aunts' ''s admission is a bellwether - it's time for ICOs to require regulatory intervention. This rectification is mainly about risk warnings and protecting investors' interests."

ICOs issue not stocks but numbers Currency is generally called a token. Blockchain startups exchange digital currencies such as Bitcoin and Ethereum through crowdfunding to achieve the purpose of financing entrepreneurship. Blockchain investors and entrepreneurs are very optimistic about blockchain technology and believe that the strong supervision by government departments is a good thing for the blockchain industry. By governing ICOs and expelling bad digital currencies, the blockchain can develop smoothly. More robust. It is hoped that this supervision can truly crack down on MLM coins and air coins, identify and treat blockchain innovation projects that are truly serious entrepreneurship, and protect the interests of serious investors and entrepreneurs.

Blockchain technology can play its role in banking, mobile payments and other fields.

④ Functional characteristics of blockchain technology

Blockchain is essentially a distributed storage system. Because it adopts a transaction accounting storage model, it also It can be called a distributed accounting system. Beijing Muqi Mobile Technology Co., Ltd., a professional blockchain development company, HuanWelcome exchanges and cooperation. Let’s talk about the functional characteristics of blockchain technology.

In traditional platform technology, central decision-making is a very common data processing method. For example, in the traditional bank transfer method, transaction information must be processed by the bank's central server cluster, and the transaction information is processed through the layers of the bank's central server cluster. The data upload and instruction distribution complete the transaction between the two accounts. Every transaction in the blockchain is directly communicated and transacted by both parties. From the initiation of the transaction to the confirmation of transaction completion, all nodes are equal and have exactly the same permissions without going through any intermediaries. This kind of The peer-to-peer transaction model in the network makes blockchain applications free from the risks of intermediary transactions.

It should be noted that although blockchain is often called a distributed ledger, and is even essentially a distributed storage system, blockchain is different from conventional distributed systems. The distributed structure is even more special. Distribution is a concept corresponding to centralization. All sub-nodes in the centralized structure only interact with the central node and have no connection with each other. Therefore, the central node needs to bear all the load. A centralized system Efficiency is basically only related to the processing speed of the central node. At the same time, once the central node encounters problems such as blocking, deadlock, and downtime, the entire centralized system will stagnate or even collapse directly. The characteristic of the distributed structure is that there are multiple nodes that can interact with other nodes for data. Distributed network storage technology stores data dispersedly on multiple independent machines and devices. This sounds a bit confusing, but it is easy to understand if it is classified and described based on the characteristics of centralization. The distributed structure includes multi-centralized structure and decentralized structure.

A polycentralized system refers to a system composed of multiple centralized systems, each of which includes a master node and several slave nodes. When performing task processing, the master node decomposes the task into multiple sub-tasks and sends them to multiple subordinate slave nodes for simultaneous processing. After the slave node transmits the processing results back to the master node, the master node will integrate the processing results of each sub-task and finally complete the task. Of course, this is just a simplified description of task processing. A multi-centralized system may have a multi-layer master-slave structure, forming a tree-like task allocation structure. At the same time, slave nodes may also take orders from multiple master nodes to maximize efficiency based on complex task management mechanisms. But the fundamental difference between multi-centralization and decentralization is whether there is a central node that controls the operation of each master node. If the top-most node is multiple nodes, then it is decentralized. On the contrary, if there is only one node at the top, it is decentralized. It's multi-centered.

In decentralization, there is a more special structure that does not have any center, which can be called a completely decentralized structure. This is also a point-to-point network structure. This structure is This is reflected in the Bitcoin network. The relative advantage of point-to-point network structure is high fault tolerance, strong node scalability, strong privacy and data consistency, etc., but there are also problems such as redundant communication and message delay.

Figure 5 Schematic diagram of network structure division

The "decentralization" emphasized in the general blockchain field mostly refers to the ownership level of the system. The system is decentralized if it belongs to the community and all accounts, and the system is centralized if it belongs to an institution or even an individual. Decentralization is a common feature of blockchain, but the completely decentralized structure of peer-to-peer networks has few current applications. Only public chains such as Bitcoin and Ethereum belong to this structure, because anyone in the world can Enter the system at any time to read data, send confirmable transactions, and compete for accounting activities, which results in the inability to guarantee its security and system efficiency. Private chains often have one or more centers that control the nodes, and all operations require permission from the center and are subject to its constraints and restrictions. Although it uses a decentralized mechanism for routine data processing, it is strictly A distributed blockchain deployment model. The alliance chain can be regarded as a collection of private chains, which is a compromise between the security and efficiency of the public chain. It adopts a multi-center technical architecture.

Due to the natural characteristics of the blockchain that cannot be tampered with, it is based on the consensus algorithm to ensure data consistency. No node in the system can tamper with or forge transactions. All transaction contents are certain and undisputed. There will be no credit risk in transactions, and the blockchain system will also have trustless characteristics.

Based on the changes in the content carried in the block from transactions to smart contracts, the trustlessness of the blockchain has two stages. The first stage is to verify the authenticity of historical transaction behaviors in the blockchain network. Trust, the second stage is trust in future transaction behavior based on smart contract rules.

The first stage of trust in the authenticity of historical behaviors can be simply understood as the blockchain system eliminates the process of proving historical transactions. When we tell others that something has happened, we need evidence to make others believe it, and this evidence often needs to be proved by a credible third party and provided with a credit guarantee through verification. For example, the electronic transaction slip provided by the shopping platform is evidence when shopping online, the tax bureau invoice provided by the restaurant when dining out is evidence, or the marriage certificate provided by the institution when purchasing a house using the identity of a couple is evidence. The person who accepts this information also needs to verify the evidence to be sure that these things have indeed happened. Corresponding to the previous article, when an online shopping dispute occurs, it is necessary to check whether the electronic transaction slip of the shopping platform actually exists; When reimbursing expenses, the signature of the invoice needs to be verified; when confirming the identity of two people as a couple, the anti-counterfeiting mark of the marriage certificate needs to be verified. However, the data of the blockchain system is considered to be non-tamperable and non-forgery, so as long as you explain a historical event to other nodes on the chain, you do not need any third-party certification, because the data on the data blockInformation can be taken out for direct verification at any time, which results in the distrust of historical transactions in the blockchain.

The second stage is trust in future transaction behavior, because in an ideal state, the smart contract of the blockchain is bound to the business, that is, the smart contract has mandatory execution in the blockchain system. force. Because the smart code is completely public and is recorded in the main chain and stored by all accounts. After the smart contract is called or triggered by a certain mechanism, the transaction will be enforced and there is no possibility of denial. Therefore, users in the blockchain system do not have to worry about the other party's credit risk in the future, and there is a lack of trust in future transactions.

In the public chain, the ledger of each node completely records all transactions. The blockchain does not directly record real-time account information, but obtains real-time account information through transaction traceability. At the same time, since anyone can create a blockchain account to form a blockchain node, the information in the public chain can be considered open to everyone, which forms the open and traceable characteristics of the blockchain. And because the code of the public chain is often open source, what is open and traceable is not only the transaction data in the system, but also the transaction rules of the entire system. The high degree of openness and transparency enables the blockchain to meet many application scenarios that require open data. .

However, the blockchain has developed many variants based on the Bitcoin network, such as light nodes, private chains and consortium chains. These variants cannot meet the strict requirements of openness. Traceable. Light nodes can only execute and verify transactions, and do not have all transaction data for traceability, so light nodes do not have traceability. However, this problem only lies in the user's choice. If there is a good enough hardware environment, the user can choose to become a full node instead of a light node in order to master all data. In addition, access permission or verification is required to join a private chain or alliance chain, and read permissions are selectively open to the outside world and are not open to the entire network, which does not meet the strict sense of openness.

⑤ What is the blockchain economy? The most important thing about the blockchain economy is the ledger

1. What must be mentioned in the blockchain economy It is a ledger. There is a block on every chain. Ledgers are also everywhere. At the same time, these ledgers do not only record transactions, but are composed of some regular data.

2. Fundamentally, ledgers describe economic and social relationships. Agreement on facts and their changes (i.e. consensus on the contents of the ledger and full trust in the accuracy of the ledger) is the cornerstone of market capitalism. Institutional cryptoeconomics gives us a tool to understand where the blockchain revolution is happening, and what we can’t predict.

3. The blockchain economy is also a phenomenon brought about by blockchain technology. Currently, many companies have adopted blockchain technology, soThe value benefits generated by using blockchain technology can be called the blockchain economy. The economic system in the general environment is also changing. What is inseparable from these systems are ledgers, so the blockchain economy must exist. the value of.

⑥ What is blockchain technology and what areas it may be used for in the future

The analysis of Jinwowo Network is as follows:
In one sentence, if Internet technology solves communication problems In other words, blockchain technology solves the problem of trust.
In layman's terms, the blockchain is a general ledger that contains all historical transactions, and each block contains several transaction records. If the blockchain is a ledger, then a block is each page of the ledger. Details of transactions are recorded on a public ledger that can be seen by anyone on the network.

⑦ A new way to track and manage digital assets, teach you how to view blockchain bills

Bills record value circulation and status, which is a basic function of financial services.

Our commonly used banks, Alipay, WeChat Pay, etc. will record a transaction for ordinary users and merchants, and provide query, statistics and analysis services in different dimensions.

For example, the Alipay annual bill that everyone loves to post will count the user's total income and expenditure throughout the year, consumption types, Yu'E Bao and other financial management income, and the number of takeaway orders. Through big data technology, consumer interests and trends in various regions and different age groups are displayed, so that consumers can better understand the consumption environment around them, and merchants can grasp market demand in a timely manner.

In a decentralized blockchain network, transactions are permanently recorded on the chain, open and transparent, and accessible to everyone.

However, since the design of the blockchain is more inclined to ensure non-tampering and data compression requirements, the filtering query function at the business level is missing. Coupled with the different rules of different chains, it becomes extremely difficult to track and manage crypto assets. This is why digital asset investors often lament that they “always feel like they don’t have a clear account.”

SixPencer launches a new blockchain accounting artifact, which currently supports asset tracking and management at the bottom of Bitcoin and Ethereum. It is free to use and does not require registration.

Once launched, it has been loved by miners, asset management institutions, OTC merchants, encryption startups, and digital asset investors.



As a professional asset management tool, it can not only query all transaction records on the chain, but also view account balances and Hold assets, and provide daily income and expenditure status of each currency, support single or multi-address aggregate income and expenditure systemPlanning, address portrait analysis and charts, large transaction record rankings, contact management, etc.

After entering the website, enter the Bitcoin or Ethereum address in the search box on the homepage, and click Search to enter the overview page of the address.

We use the address that currently ranks first in ETH holdings on the entire network: (tag: bitfinex 1) account as a demo account for demonstration, and all data are real on-chain data.


Here is a brief introduction to the difference between addresses and bank accounts on the blockchain. On the blockchain, an address is similar to a bank card number. Knowing the address is the same as knowing the bank card number, and you can transfer money to it.


But the difference is that the blockchain is a distributed public ledger that cannot be tampered with. It is usually anonymous and anyone can conduct public queries on any address. The bank account can only query your own account information, and you cannot know other people's account information through the bank card number.

If the user has multiple addresses or wants to track other addresses, they can search. All searched address information will be summarized on the asset portfolio page. Click the drop-down box to switch or delete accounts.

In addition to the basic information provided by the blockchain browser, SixPencer also displays some personalized indicators to help users understand their own on-chain portrait and track the on-chain trajectories of other accounts. On the overview page below, you can view the address's asset overview, historical indicators, income and expenditure statistics, and asset holding information.

Address overview

Creation time: date of first receipt of ETH

Net assets: all assets, including ERC20 tokens Total USD value of assets

ETH ranking: Ranking of all Ethereum addresses holding ETH amount

p>

ETH balance and valuation: Amount of ETH held and its corresponding USD value

Historical indicators

< p> Historical indicators display four major dimensions: transaction volume, number of transactions, token analysis and contact analysis. Through statistics, the unclear accounts can finally be settled. For example, the simplest accounting calculation, ETH total income = ETH balance + ETH total expenditure + ETH total handling fee. Another example is the total number of transactions = the number of transfer-in transactions + the number of transfer-out transactions.

Due to the particularity of the Ethereum network, all transfer fees are paid in ETH. Therefore, we list the handling fees separately, and also support separate screening of handling fees in the transaction details to help users count handling fee expenditures.


Some interesting data, the demo account fee is 1.1556ETH, a single large ETH transfer reaches 900,000 ETH, and the number of tokens held is There are 350 types, and the most traded token is USDT, with only 37 addresses that have been traded with it.

Addresses that hold hundreds of different assets are usually exchange addresses. In addition, the number of transactions and contacts are not many, so it can be ruled out that it is an external address, and it can basically be judged that it is used internally by the bitfinex exchange. address.


Income and Expenditure

Statistics of the total income and expenditure of all assets this month, including handling fees.

Asset holdings

Displays the number, value, asset price and 24h increase or decrease of assets held. The address of an exchange such as a demo account, which holds assets, usually does not fit on 10 pages.

In addition to providing the transaction flow of addresses, SixPencer also supports query and filtering of full historical transaction records, balance information, daily income and expenditure statistics, etc.

Transaction details

From the following page, you can clearly know the income and expenditure of ETH assets this month. Users can also filter based on date, fund flow, transaction classification and labeling system. If you need more detailed statistics, we will introduce how to filter transactions at specified addresses later.

Click the ETH drop-down box in the picture above to switch to the transaction details page of other currencies. For example, switch to the transaction details of USDT to view the detailed status of USDT.

In addition to monthly bills, SixPencer displays everyThe transaction details of the transaction provide information such as transaction direction, counterparty, transaction amount, account balance, transaction time, daily income and expenditure, etc. As you can see in the picture below, the nearly 6 ETH transactions were all transactions transferred from the bitfinex 3 account to bitfinex 1.

Transaction details

Click on any transaction details to enter the transaction details page of that transaction. The transaction hash is a unique and immutable transaction ID for each on-chain transfer, similar to the concept of an order number.

The specific information of a transaction can be queried through the transaction hash.

The transaction quantity, transaction status, transaction time, sender and recipient, handling fee, etc. shown below are the specific information of this transaction and will not be repeated here. It is worth noting that SixPencer provides a personal tag and remark system. Users can make personalized classifications and notes for individual transactions to help remember and not forget every transaction.

How to quickly find and specify the transaction information of the address?

As time goes by and the number of transactions increases, it becomes extremely complex and difficult to query the specified transaction information on the chain. SixPencer refines the transaction information according to business needs and provides a tag system to assist users in customization. Transaction inquiries and statistics.

For example, you want to query the total amount of ETH transferred to the demo account from the address (label: bitfinex 3) in June 2020. Through our billing system, it only takes two steps to check.

1. Label: For demonstration, we will rename the label "bitfinex 3" to "test test".

2. Filter: Filter the dates to June 1st - June 30th, select "Transfer" in the filter bar, select "Test" in the bottom tab bar, and click Save.

After saving, you can search for all the transaction information transferred to the demo account from "test test" in June. As can be seen from the picture below, in June, the demo account transferred from the address labeled "test test" 58,440.2489 ETH received.

If the user wants to query transactions with multiple specified addresses, select multipleAfter labeling, adjust the date, capital flow and other information to perform automatic statistics of assets.

In the analysis column, users can query the chart analysis information of the address in different dimensions, including the four major dimensions of balance, transaction, classification and ranking. You can also view more detailed data and charts by clicking on each dimension separately.

Balance: Balance displays the balance quantity and value trend of assets

Transaction: Transaction displays all transactions, the number of transactions transferred in and out, and the number of transactions Trends in value and number of transactions

Classification: Classification counts transaction types based on the platform's address label system, reflecting the transaction preferences of the address

< p>

Ranking: The ranking displays active contacts according to the number of transactions, and displays large transactions according to the transaction amount

For example, ranking Analysis, you can quickly check the specific transaction amount and large transfer status with a certain address. As shown in the figure below, the demo account and the address labeled "test" have a total of 177 transactions this month. Other transactions with the demo account that have more transactions are ERC20 Token contract call transactions.

From the picture below, the large-amount rankings are also transaction information with the address labeled "test". The table displays the transaction object, transaction time, transaction direction, transaction quantity and value. If you are interested in large accounts on the exchange, you can check the large transfer information of the exchange address to see which addresses are large deposits and withdrawals.

The address book displays all addresses that have transaction records with the demo account. In addition to the platform's own label system, users can add labels to addresses or rename labels.

Tags: tags known by the display platform tag system and tags added by users

Recent Contacts: Displays addresses/labels with transaction records in the last 30 days

All Contacts: Displays all contacts with transaction records Addresses/labels, addresses with more than 10,000 transactions, display the contacts of the last 10,000 transactions

In summary, SixPencer’s newAsset tracking and management tools can provide more comprehensive query and analysis functions than blockchain browsers or wallets. As a tool product, it is intended to assist users in digital asset management. Through further analysis of user portraits on the chain, it can help everyone more Good decision making.

We believe that the open and transparent mechanism of blockchain should make data query easier, but currently it is still difficult and painful to quickly query blockchain data according to actual business needs, and has become a major obstacle to commercial implementation.

Digital asset transactions are only a small part of it. A large amount of valuable data will be stored on the blockchain in the future. SixPencer will continue to launch more practical tools to allow Data better serves the business.
