『一』 TP wallet address how to track and query transaction details

View history.
To track the transaction details of tp wallet address, you can click on my homepage on the platform to view the historical records. However, please note that if the record time is too long, it will be automatically deleted.
Tokenpocket wallet is a decentralized multi-chain wallet. At the same time, it is also a very safe and reliable wallet. It is very safe to store various currencies such as EOS, ETH, BTC, etc. The TokenPocket wallet function also greatly improves the convenience of operation while ensuring the security of the wallet to the maximum extent. Decentralized wallets do not save users’ private keys, and coins are stored on the blockchain rather than in the wallet. Therefore, as long as your private key is not leaked, your assets are safe. Even if the wallet runs away, you can import the private key into other wallets and continue to manage your assets. TokenPocket is the wallet with the largest traffic volume in the EOS ecosystem and is also the largest DApp store. As a decentralized universal digital wallet that supports multiple currencies and multiple underlying layers, TokenPocket integrates digital asset management, trading, financial services, resource leasing, node voting, market information, DApp distribution, and IM (instant chat), etc. Function. Tokenpocket is like a powerful DAppStore. The most popular DApps based on the EOS ecosystem will be launched on TP as soon as possible. Tokenpocke is compatible with Scatter. Most DApps on the market only support the web version, which is very inconvenient for mobile users. Now all DApps that have been connected to the Scatter interface can perform all operations in Tokenpocke's DApp browser, which is extremely convenient for users and developers. In the DAPP area, it currently supports eight major public chains, EOS, ETH, IOST, BOS, COSMOS, MOAC, Jingtum and ENU, and 2,000 DAPPs, covering spinach, games, candy boxes, exchanges, tools, communities, mining, etc. Types of DAPP.

『二』How to implement query and search on blockchain data

Blockchain is a new application of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. model. The so-called consensus mechanism is a mathematical algorithm in the blockchain system that enables different nodes to establish trust and obtain rights and interests.

In a narrow sense, blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and non-tamperable. Unforgeable distributed ledger.

Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, and uses cryptography to ensure data mastery. The security and convenience of transmission and accessA new distributed infrastructure and computing paradigm that uses smart contracts composed of automated script code to program and manipulate data.

Generally speaking, the blockchain system consists of the data layer, network layer, consensus allocation layer, incentive layer, contract layer and application layer working together to complete the query and search of data.

『三』 IBM Walmart applies blockchain technology to prescription drug tracking

IBM, KPMG, Merck and Walmart are joining forces with the FDA to create a proof-of-concept blockchain network. The project, linked to the U.S. Drug Supply Chain Security Act, is designed to help the FDA and other organizations in the drug supply chain develop a blockchain network to identify and track the distribution of prescription drugs.

As the blockchain famous saying goes: it builds trust when you need it most! IBM's global solutions leader Mark Treschuk said that blockchain can provide an important new method to further improve trust in the biopharmaceutical supply chain. Blockchain technology can not only provide an audit trail to track drugs in the supply chain, but also track who shares data and who shares it with whom, without revealing the contents of the data itself. Blockchain therefore has the potential to change the way drug data is controlled, managed, shared and acted upon throughout its lifecycle.

IBM has been committed to the research and development of blockchain technology in recent years, and has been applied in fields such as shipping, food, banking and hard drives. In 2016, Walmart partnered with IBM to apply new food safety to its suppliers, applying blockchain technology to achieve traceability throughout the food supply chain. In addition, IBM and Maersk have formed a joint venture focusing on global trade, aiming to create a blockchain platform to serve trading partners around the world.

China is also establishing new standards for food supply chain safety, relying on the eyes of IBM, Walmart, JD.com and Tsinghua University to use blockchain technology to collect data on the origin, safety and authenticity of food.

The widespread application of blockchain technology will change people’s lives. From wearables to food, it changes people’s understanding of ordinary things. After applying blockchain, ordinary items will be redefined, and consumed items will not disappear out of thin air. Blockchain technology will make a world defined by matter. , truly becomes a digital world, and every seed that disappears on the earth will be remembered forever!

『四』Digital currency is a thief and anti-corruption, but if paper currency is used, how to track it?

There are many problems in tracking between digital currency and paper currency. Big difference.
For digital currency, since its transaction records are stored on the blockchain, each transaction is public and cannot be tampered with, so it can be tracked through blockchain technology. Blockchain technology can record the source, destination, time and other information of each transaction, making it impossible for any transaction to be deleted.Remove or modify. At the same time, blockchain technology can also implement smart contracts, allowing both parties to complete transactions without relying on a third party, thereby further improving the security and transparency of transactions.
For paper currency, since its transaction records only exist in the banking system, it can be tracked through the banking system. The banking system can record the time, amount, payee and other information of each transaction, and can determine whether the transaction is legal and whether there are any violations by querying the transaction records. In addition, the banking system can also identify potential risky customers through risk assessment models, thereby further reducing transaction risks.
In short, whether it is digital currency or paper currency, it has its own unique tracking method. Digital currency pays more attention to the application of blockchain technology, while paper currency pays more attention to the use of the banking system. No matter which method is adopted, complete regulatory mechanisms and technical means need to be established to ensure the security and transparency of transactions.

『Wu』 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 on-chain transaction records, view account balances and held assets in real time, but also provide daily income and expenditure status of each currency, support single or multi-address aggregate income and expenditure statistics, and address portraits Analysis and charts, ranking of large transaction records, 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, 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, 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 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 helps 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. 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.

『Lu』The digital currency was transferred to a scammer, can you find the other party based on the address?

This should be able to find the other party, (now Login to the platform, account... are all real-name authentication, and it is not easy to take advantage of legal supervision loopholes.) Now network supervision is gradually improving, login nicknames are very strict, and all are real-name authentication.

『撒』How can blockchain agriculture make every link of agricultural products transparent and traceable

It can provide consumers with origin information and make people more assured.

『8』How much does it cost to develop a blockchain product life cycle tracking solution?

The so-called product life cycle tracking refers to the process from people’s demand for products to the elimination of products. Tracking of the entire life course. Since the blockchain is non-tamperable, this is the best way to track it. Product life cycle tracking can be for different products, so there will be different solutions. This is the case with Yingtang Zhongchuang's blockchain commodity life cycle tracking solution, which provides a multi-product tracking solution.

『玖』How is the anti-counterfeiting traceability application of blockchain implemented?

The three major characteristics of blockchain are well known, which are decentralization, openness and transparency and inaccessibility. tamper. The non-tamperable feature enables blockchain to be used in many places. Such as product traceability, anti-counterfeiting, privacy protection, etc.

Because the production process it traces is all uploaded manually, so even if the data cannot be tampered with, the authenticity of the data cannot be guaranteed, and it still cannot be Solve substantive issues.

In general, although blockchain has brought great benefits, it is not perfect after all. However, blockchain technology has advanced the development of the times, and I believe its future is worth looking forward to.

『Shi』How to view Ant Blockchain traceability

Ant Blockchain traceability still has certain development prospects.

Blockchain traceability must anchor the physical and digital worldsrelationship, but each link can only operate on their own parallel lines, making it difficult to achieve absolute traceability. Moreover, the corresponding nodes of the Ant traceability blockchain solution can only be deployed on Alibaba Cloud.

It is fully managed by a third party of Ant Technology and cannot be deployed in upstream and downstream or industrial and commercial regulatory agencies, which further degrades the ability of decentralized anti-tampering. This solution should be a way of brand gain.
