⑴ "Block Eye" was removed from the shelves, suspected of providing diversion services for virtual currency transactions

The official website shows that "Block Eye" is a blockchain industry The platform information query tool is developed by WikiBit and its main company is Shanghai Wancha Data Technology Co., Ltd.

According to the industrial and commercial information on Tianyancha, Shanghai Wancha Data Technology Co., Ltd. was established on April 9, 2020, with a registered capital of 1 million yuan, the legal representative is Zhang Nanping, and the major shareholder is registered in Hong Kong AFFIX LIMITED.

According to the official website of Blockchain Sky Eye, its core function is to provide basic information inquiry, regulatory license inquiry, credit evaluation, platform identification and other services for included blockchain projects.

This includes cryptocurrency exchanges, tokens, project information inquiries, word-of-mouth inquiries, complaints and rights protection, risk exposure, credit evaluation, etc. It can monitor cryptocurrency trading platforms, tokens or surrounding dynamic risk contracts in real time. regulation. At the same time, it will also provide users with services such as cryptocurrency market conditions, blockchain industry news, and industry book sales.

As of September 7, the platform has included 5,837 exchanges, 8,364 tokens, and 26 regulatory agencies. Industry insiders call it the "eye of the sky" in the currency circle.

It is worth mentioning that in mid-July, another domestic blockchain industry self-media "Coin World" APP was also removed from the shelves. For details, please see "Blockchain Self-Media Coin World Was Interviewed" Shut down ZhenFund, Shunwei Capital and other investors.”

On May 21, the Financial Stability and Development Committee of the State Council made it clear that it would crack down on Bitcoin mining and trading. Subsequently, a new round of virtual currency supervision was launched across the country, and regulatory actions covered the upstream and downstream, multiple links, and all aspects of the industry.

Recently, the People's Bank of China has just released the "China Financial Stability Report (2021)" (hereinafter referred to as the "Report"), which mentioned that it will strengthen the supervision of financial activities of platform companies and crack down on Bitcoin mining and trading activities. . Efforts should be made to make up for the shortcomings of the regulatory system, speed up the improvement of the modern financial regulatory system, and strengthen regulatory coordination. We will improve the financial risk accountability mechanism, strictly hold accountable major financial risks, and effectively prevent moral risks.

In addition, the "Report" also proposed in the main results of the battle to prevent and resolve major financial risks that the financial order has been comprehensively cleaned up and rectified. All operating P2P online lending institutions have ceased operations, and rectification work in areas such as Internet asset management, equity crowdfunding, Internet insurance, virtual currency trading, and Internet foreign exchange trading has been basically completed, and has been transferred to normalized supervision.

⑵ Where can I check blockchain?

Blockchain? Do you mean blockchain technology, blockchain information, or things related to the blockchain industry?
1) If it is just "blockchain", then you can search directly on the Internet to find a good explanation of "blockchain network".
2) If it is "blockchain"Technology", similarly, the Internet has a good interpretation, and all walks of life are also trying to combine with blockchain technology in new fields. In the future, maybe blockchain technology will be used correctly instead of being used to fool people.
3) If it is "blockchain information", then you can go to various blockchain media or financial media. There are almost every day relevant blockchain industry information and news reports. Such as: Babbitt, Biyou Finance , Blocknet, Golden, Daily, etc.
4) If it is "blockchain audio", you can go to Ximalaya FM, Lizhi Micro Class, Qianchao and other platforms to listen. Like "Biyou Voice" , "Yu Lingxiong", "Wang Feng" and other financial media have good blockchain-related audio, with various useful information and in-depth analysis.
So, where can you check the blockchain you mentioned? The above 4 points It’s all related to blockchain, it’s up to you to choose.

⑶ A new way to track and manage digital assets, teach you how to view blockchain bills

Bills record value circulation and status , 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 for the year, consumption types, Yu'e Bao and other financial management income, the number of takeaway orders, etc. Through big data technology, it can display various regions and different ages. segments of consumer interests and trends, allowing consumers to better understand the consumption environment around them, and merchants to grasp market demand in a timely manner.

In a decentralized blockchain network, transactions are permanently recorded on the chain It is open and transparent and can be checked by everyone.

However, because 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. Plus the rules of different chains Different, it has become extremely difficult to track and manage encrypted assets. This is why digital asset investors often lament that “I always feel that the accounts are not clear.”

SixPencer launches a new blockchain accounting artifact, Currently, it supports asset tracking and management of the underlying assets of Bitcoin and Ethereum. It is free to use and does not require registration.

Once launched, it has been welcomed by miners, asset management institutions, OTC merchants, encryption Favored by startup companies and digital asset investors.

As a professional asset management tool, it can not only query all Transaction records on the chain, real-time viewing of account balances and assets held, and provision ofDaily income and expenditure of each currency, support single or multi-address aggregate income and expenditure statistics, address portrait analysis and charts, large transaction record ranking, 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 settledWell, for example, the simplest accounting calculation, total ETH income = ETH balance + total ETH expenditure + total ETH 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 the transaction details of each transaction, providing information such as transaction direction, counterparty, transaction amount, account balance, transaction time, daily income and expenses, 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 multiple tags and adjust the date, fund flow and other information to perform automatic asset statistics.

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 Address/label, for addresses with more than 10,000 transactions, display the contacts of the last 10,000 transactions

In summary, SixPencer’s new asset tracking and management tool 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 on-chain Further analysis of user portraits helps everyone make better decisions.

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.

⑷ How to check other people’s blockchain information

1. If you are checking account balance, historical transaction data of the account and other information, it is recommended Directly enter the wallet address to query; if you are querying relevant information about a certain transfer, such as whether it has been received and how the progress is, it is most convenient to enter the transaction ID. Of course, the blockchain browser can not only query your own account, but also query all contacts of other people's accounts: display all contact addresses/tags with transaction records, addresses with more than 10,000 transactions, and take the most recent 1 Contact display for 10,000 transactions In summary, SixPencer’s new asset tracking and management tool can provide more comprehensive query and analysis functions than a blockchain browser or wallet. As a tool product, it is intended to assist users.
2. It can be queried through the blockchain browser. In the blockchain browser, we can know what transactions a wallet address has conducted, how many assets are on the account, etc. You can view it with a blockchain browser. Enter the wallet address you want to query in the search input box. If the address you enter is incomplete, but this address has been ETH traded or queried on the blockchain before, the input box will automatically query it for you

⑸ Can the blockchain address be queried?

It can be viewed with a blockchain browser.
If the address you entered is incomplete, please enter the wallet address you want to query in the search input box. However, after this address has previously conducted ETH transactions or queries on the blockchain, the input box will automatically fill in the address you query. address.
Click Query and all information about the wallet address will appear.
Click on the transaction hash to also see the details of the transaction.
The principle of querying the blockchain browser:
Because the transaction information and other data in the blockchain are open and transparent, the blockchain browser is the address for querying the blockchain transaction records, and users can use It looks at its own transaction information and other information stored on the blockchain.
Most of them can be checked, which is a major feature of the openness and transparency of the blockchain. The address is transparent. As long as there is an address, you can query the transfer.

What is the blockchain for?

What is the blockchain for? There are many things in the world that touch our knowledge blind spots, and blockchain is one of them. However, blockchain is often mentioned, so we also need to understand blockchain. Next, I will take you to understand what blockchain is for.

What is blockchain for? 1

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm.

Blockchain is an important concept of Bitcoin. It is essentially a disintermediated database. As the underlying technology of Bitcoin, it is a series of related cryptographic methods. Each data block contains information about a Bitcoin network transaction, which is used to verify the validity of its information (anti-counterfeiting) and generate the next block.

Applications

1. Art industry

Ascribe allows artists to use blockchain technology to declare ownership and issue certificates. Numbered, limited-edition pieces can be used in digital form for any type of artwork. It even includes a marketplace where artists can buy and sell through their website without the need for any intermediary services.

2. Legal industry

BitProof is the most advanced of the many document timestamp applications that have emerged in recent years, and will make traditional notarization methods a thing of the past. Compared with free versions including Blocksgin and OriginStaemp, BitProof provides more services, including one for intellectual property. Interestingly, BitProof recently collaborated with a San Francisco IT school to put all their students’ academic certificates on the blockchain, completely redefining how diplomas and student certificates are processed and used.

3. Development industry

Colu is the first company to allow other companies to issue digital assets. Their ability to "tokenize" various assets has impressed many people. While the free Bitcoin wallet Counerparty also allows simple tokens to be issued and traded among other wallet holders, Colu's tokens can be configured in various states and types, be able to leave and return to the system, and When storing data on the blockchain is too large, the data can be stored on the BitTorrent network.

4. Real estate industry

They plan to modernize the entire industry chain process and solve various problems faced by everyone involved in real estate, including the naming process, land registration, Agency intermediaries, etc.

What is Blockchain 2

What is Blockchain

Blockchain is a new application of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. model. It is an important concept of Bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of Bitcoin, it is a series of data blocks generated using cryptographic methods.

Each data block contains a batch of Bitcoin network transaction information, which is used to verify the validity of the information, prevent counterfeiting and generate the next block. It is a set of data storage mathematical architecture constructed in a way that is almost impossible to forge or tamper with, and can be used to store all kinds of valuable data.

The Cyberspace Administration of China issued blockchain information service management regulations on January 10, 2019, which will take effect on February 15, 2019.

What is the blockchain for 3

Before talking about the blockchain, let’s talk about the Internet. The Internet is now an indispensable part of us and is closely related to our lives. First of all, the biggest disadvantage is It can only transmit information. The key is that the information data on the Internet can be set artificially. For example, it is often said to browse Weibo and so on. Secondly, there are bugs in the Internet environment, which means that there cannot be equality in data ownership. This is to say that there are some disadvantages of the Internet.

Putting aside what blockchain is, let’s talk about the Internet and blockchain. Blockchain and the Internet are a parallel relationship, or they can be a complementary extension of each other.Continued. So what is a blockchain? A blockchain is actually a series of data blocks that are associated using cryptographic methods. Simply put, there are many data blocks connected in a certain time sequence. It can also be said that a blockchain is a ledger. , but the account book is different from the ordinary computer account book. The blockchain account book is jointly kept by all computers in the world. The biggest feature is that it cannot be tampered with.

What can the blockchain do?

1. Machine trust

In professional terms, it is because of the blockchain The tamper-proof nature of technology fundamentally changes the centralized credit model. Build lowest-cost credit with code. In other words, as long as the code on the blockchain is executed, there is no need to worry about the possibility of stopping midway. Creating a new era of machine trust. Blockchain is expected to lead us from personal trust to the era of machine trust. In other words, his trust cost is close to zero.

2. Value transfer

The Internet can only transfer information but cannot realize the value of information. In other words, the transition from the information Internet to the value Internet will Some fundamental changes occur. Blockchain transfer will be more convenient, while also achieving low-cost transfer of value.

3. Smart contract

This is also one of the most obvious features of the blockchain. When a pre-programmed condition is triggered, the smart contract begins execution and cannot be interrupted by either party, and cannot be deleted, modified, etc. until the end of the contract.

4. Token mechanism

Token mechanism is actually a form of value circulation. Through the tokenization of physical or virtual assets, it can work directly through the network. Mainly There are cost reductions, time savings and crossing borders. It can also be understood as proof of rights and interests. Xunlei and "LinkToken" all belong to the "Token" blockchain.

Blockchain characteristics

It has the characteristics of decentralization, anonymity, autonomy, openness, traceability, non-tampering, collective maintenance and no need for recognition. At present, we often talk about the following types of blockchains: public chain, private chain, alliance chain and side chain.

The application value of blockchain

1. Blockchain information security

Information security is one of the biggest features of blockchain, such as Facebook some time ago The leaks brought some negative social impacts. On May 8, Facebook established a blockchain department to study how to use blockchain technology.

2. Underlying technology

This is one of the most imaginative and core technologies of the blockchain. This is a highly professional academic. Let’s give a simple example. , the most famous project of this underlying technology is Ethereum.

3. Bass service

This is the data generated using the blockchainA series of services are provided, such as query, etc. In terms of the network, Tencent has launched its own Bass service.

Where are the five blockchains mainly used?

At present, relatively mature areas include blockchain + medical care, blockchain + Internet of Things, blockchain + culture and entertainment, blockchain + public welfare, etc.

⑻ What is blockchain

Blockchain is a term in the field of information technology. In essence, it is a shared database, the data or information stored in it , with characteristics such as “unforgeable”, “leaving traces throughout the entire process”, “traceable”, “open and transparent” and “collectively maintained”.

On January 10, 2019, the National Internet Information Reform Office issued the "Blockchain Information Service Management Regulations". On December 2, 2019, the word was selected into the top ten buzzwords of 2019 by "Yi Wen Qi Zi".
