⑴ What are the basic characteristics of blockchain

Answer: The basic characteristics of blockchain

1. Decentralization.
Blockchain technology does not rely on additional third-party management agencies or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, through distributed accounting and storage, each node realizes self-verification and transmission of information. and management.

2. Openness.

The foundation of blockchain technology is open source. In addition to the private information of the parties to the transaction being encrypted, the blockchain data is open to everyone. Anyone can query the blockchain data through the public interface. and develop related applications, so the entire system information is highly transparent.

3. Independence.

Based on consensus specifications and protocols (similar to various mathematical algorithms such as the hash algorithm used by Bitcoin), the entire blockchain system does not rely on other third parties, and all nodes can automatically and securely operate within the system. Verification and exchange of data do not require any human intervention.

4. Security.

As long as you cannot control 51% of all data nodes, you cannot arbitrarily manipulate and modify network data. This makes the blockchain itself relatively safe and avoids subjective and artificial data changes.

5. Anonymity.

Unless there are legal requirements, technically speaking, the identity information of each block node does not need to be disclosed or verified, and information transfer can be done anonymously.

⑵ Can I check the usdt address?

It depends on the situation. The address itself is anonymous and cannot be found by ordinary people. Only the public security department can query the address information through technical means.

Blockchain address generally refers to wallet address. The wallet on the blockchain is a tool for managing digital assets. The transfer of coins in and out and the records of transfers in and out are all achieved through the wallet. In a blockchain system, the private key is generally a 256-bit binary string randomly generated by a special random algorithm. The public key is generated from the private key through an irreversible algorithm, and the public key obtains the address through an irreversible algorithm (note : The address in some blockchain systems is the public key, and the address of the public key is calculated again to make the system more secure).

⑶ 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 to query the blockchain transaction recordsaddress, which users can use to view their 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.

⑷ 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 It holds assets and provides daily income and expenditure in various currencies, supports single or multi-address aggregate income and expenditure statistics, 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, 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, the number of tokens held is 350, and the number of transactions is the highest The token is USDT, and there are only 37 addresses with which it has been traded.

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, transaction 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 enterThe transaction details page of this 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 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, transfer-in and transfer-out transactionsQuantity, transaction quantity value and transaction number trends

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

< p> For example, ranking analysis can quickly check the specific transaction amount and large-amount transfers 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/tags, addresses with more than 10,000 transactions, display of contacts for the last 10,000 transactions

In summary, SixPencer’s new asset tracking and management tools can provide It has more comprehensive query and analysis functions than a blockchain browser or wallet. As a tool product, it is intended to assist users in digital asset management and help everyone make better decisions through further analysis of user profiles on the chain.

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. In the future, a large amount of valuable data will be stored on the blockchain. SixPencer will continue to launch more practical tools to make data better serve the business.

⑸ What is blockchain and what fields is it used in?

1. What is blockchain? One sentence summary.
Answer: Blockchain is an encrypted database chain, that is, transaction data in multiple timestamps/events are encrypted and associated together. The data cannot be tampered with and can be shared.
2. Performance and logic:
a. External operation manifestations: bank deposits, withdrawals, remittances, incoming and outgoing accounts, shopping, currency issuance, capital transactions, etc.
b. Internal logic processing (software program): After manual operation, the data will be encrypted and then stored in the database. The data will be divided into areas through the program, such as classifying and putting together the data that occurred within the event and timestamp. is the data for a region. The association of data occurring within multiple events and timestamps is the blockchain. The encrypted data can be shared but cannot be tampered with.
c. Sharing manifestations: querying personal information, checking accounts, etc. Query permissions/sharing permissions: Different permissions query different data. For example, a bank can check everyone's information, but an individual can only check personal information.
3. Most of the examples given are different, but the logical processing ideas are the same, but the implementation methods and operations are different.
4. Blockchain: It has the characteristics of encrypted data, non-tamperable data and shared data.
5. Blockchain technology: a technology that uses editing programs to encrypt, partition, and share data.
I have suggestions and would like guidance.
Application fields: finance, IT, merchandise sales, online shopping, etc.

⑹ How to query blockchain coins on Ethereum

You can directly query by entering information such as wallet address, transaction ID, block hash or block height, which is very convenient.
If you are querying account balance, historical transaction data of the account and other information, it is recommended to directly enter the wallet address to query; if you are querying relevant information of 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 other people's accounts and related transaction information, including the account of Bitcoin founder Satoshi Nakamoto.

⑺ What is blockchain, how to simply understand blockchain technology

What is blockchain

Blockchain is through point-to-point transmission, A new technology that performs encryption algorithms. There are countless points in the blockchain. Each point represents a user. If a transaction occurs between points, the transaction record will be directly uploaded to the block. The data in the block will be uploaded according to time. Linked sequentially is a blockchain.

1. Blockchain is also called a distributed ledger, which records the transactions of all nodes.Records, each node needs to maintain the development of the blockchain, supervise whether the transaction is legal, and can also testify for the transaction together.

2. Encryption technology. The transaction information in the blockchain is public, but the personal information has been encrypted. There is no need to worry about the leakage of personal information. Only with the authorization of the individual can the other party Personal information is queried and the security of personal information is guaranteed.

3. Consensus mechanism. Every node in the blockchain trusts each other. Every user can trade with confidence because the data cannot be tampered with and every transaction must be legal and will not There is a possibility of fraud.

4. In scenarios where smart contracts and blockchain technology are applied, intelligent matching can be used. For example, insurance claims can be automatically settled.

How to simply understand blockchain technology

Blockchain technology can be understood in this way. Xiaohei and Xiaobai are both nodes in the blockchain. Borrowing 1,000 yuan is a transaction, and the data will be stored in the block. At this time, Xiaobai broadcasts to everyone that Xiaohei borrowed 1,000 yuan from him, and Xiaohei also broadcasts that he borrowed money from Xiaobai. He borrowed 1,000 yuan from Xiaobai. Everyone heard the news. On the repayment day, Xiaohei said that he had not borrowed 1,000 yuan from Xiaobai. At this time, everyone came out to testify to Xiaobai that Xiaohei had indeed borrowed money. 1,000 yuan.

In the above example, Xiao Hei and Xiao Bai are equivalent to the two nodes of the blockchain. Borrowing money is a transaction. As long as the transaction is made, transaction data will be generated and uploaded directly to the block. The data in the block is public. Not only can you see it, but everyone in the blockchain can see it. This ensures that Xiaohei will not breach the contract and say that he did not borrow the money. Everyone in the block will supervise Xiaohei. To repay the money, it ensures the legality of the transaction and mutual trust between each node.

⑻ How to view the blockchain assets (digital currency) of the address through the blockchain asset address (digital wallet address)

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 previously conducted ETH transactions or been queried on the blockchain, then the input box will Automatically complete the address you query.

Click "Query" and all the information about this wallet address will appear.

Click "Transaction Hash" to see the details of the transaction.

The principle of blockchain browser query:

Because the transaction information in the blockchain, etc. The data is open and transparent, and the blockchain browser is an address for querying blockchain transaction records. Users can use it to view their own transaction information and other information stored in the blockchain.

The vast majority can be checked, which is a major feature of the openness and transparency of the blockchain. The addresses are all transparent.As long as you have an address, you can check its transfer in and out.

A friend mentioned the anonymous currency, so I won’t go into details. In other aspects, it is also a tool to check the authenticity of the project. Some funds under the guise of blockchain issue some coins to deceive investors. You can go to the browser to take a look. Sometimes there is no data on the chain at all, which proves that the points are issued by themselves.
