September 23, 2024, a day to struggle with on-chain data! 🤓🔍

Early morning task: Get N transaction hashes through the wallet address, and then get event logs through these hashes and store them in the database, opening a new chapter in on-chain data research! Unexpectedly, QuickNode's API restrictions are a headache. Only 5 blocks of data can be retrieved at a time. After changing and changing, the code is being frantically optimized...😅💻

Finally, the block limit was solved, but new problems emerged: the network communication bottleneck became the biggest stumbling block, slowing down the speed, and it felt like the entire progress was crawling at a snail's pace🐢🌐.

In order to get rid of these obstacles, our full node service made a brilliant debut! 🎉 It was finally successfully started just now, and it was actually in a stopped state before (this oolong is also unique...)😂.

Now we just have to wait for the node to synchronize the subsequent data, and the research on on-chain data has taken a big step forward! 🚀📊

Special thanks to GPT-4 for helping me clear minefields and solve puzzles along the way, otherwise I would have to drink a few more cups of coffee to survive ☕️😅. This wave is worth it, the on-chain data research has just begun, and greater excitement is yet to come! 💪🔥

UK lawmakers urge government to build a pipeline of cryptocurrency and blockchain skills training

Members of the UK Parliament have unanimously called on the government to increase investment in skills that meet job demands in the cryptocurrency, blockchain and artificial intelligence (AI) industries. During a debate on Tuesday, MP Lisa Cameron stressed that the government should ensure digital skills are taught from the early stages of education and even in the workplace.
“While the UK is well placed to take advantage of the opportunities presented by the growth of the digital economy, we still need to make significant preparations and investments in education, training and skills to make the most of these opportunities and ensure that the UK has the necessary talent.” #BTC、 #区块链开发 #人工智能

How do you view virtual currency and blockchain?

Blockchain, in simple terms, is a set of encrypted distributed accounting technology. "

Encryption is a mathematical concept, distribution is a network concept, and accounting technology is a financial concept.

Generally speaking, it is difficult for ordinary people to understand blockchain because this concept involves three complex disciplines, but you don't actually need to remember this definition, you just need to remember the centralized accounting technology.

The so-called centralized accounting is the accounting method currently adopted by the financial industry. For example, if you have 10,000 yuan in a bank, this 10,000 is stored in the form of data in the bank's centralized database. In order to prevent accidents, the bank may back up the database in a very safe place. If you want to transfer 100 yuan to Zhang San, the bank only needs to add 100 yuan to Zhang San's account and subtract 100 yuan from your account, and the entire transfer process is completed.

Why blockchain is better

The advantage of centralized accounting is efficiency and convenience. After receiving your transfer instruction, the bank's settlement system can complete this operation within milliseconds. However, centralized accounting also has many disadvantages:
The first is that the bank has an extreme event: it is attacked by hackers or the system has serious bugs, and it is directly completely The bottom of the bank is destroyed or tampered with, and even the backup database is destroyed. The possibility of this happening seems small now, but the probability still exists. In this case, all your wealth in the bank will be instantly cleared, and society will fall into chaos.

Second, credit collapse: The centralized accounting method relies on centralized credit. Once this credit has problems, such as the bank stealing and privately tampering with customer bank data, this has happened many times. The bank privately steals customer funds in violation of regulations, and then the bank begins to shirk responsibility and says that it is the personal behavior of bank employees and the bank is not responsible. Although it is likely that most of the funds can be recovered through prosecution, this process makes customers miserable; in addition, if the credit supporting this center collapses, the current centralized credit is behind the country. What if the credit of this country collapses? Your money in the bank is just a pile of waste paper, such as Zimbabwe back then.

Although the probability of the above two extreme situations is very low, it is still possible, and the emergence of blockchain perfectly solves the above-mentioned centralized pain points, because the accounting method of blockchain is "distributed accounting technology."

Continuing to use the above example, if you have 10,000 yuan and need to transfer 100 yuan to Zhang San, then this transfer will not be recorded in the centralized database, but will be broadcast to all nodes in the entire network, and they will Every transfer is recorded in its own ledger, that is, every node participating in this system has a ledger recording the transaction.

If someone wants to tamper with this data at this time, they must convince more than 51% of the nodes in the entire network to help you tamper with it at the same time. As long as there are enough participating nodes, the possibility of this happening is almost zero.

Why is it important?

There are many extremists on the Internet. Even people in the currency circle such as Liang Xi and other lunatics do not actually recognize the blockchain. They have one purpose in the field, and that is to make money.
In fact, this kind of people, especially as a KOL, are extremely harmful in the currency circle. They will mislead many people and turn many novices into gamblers when they enter the market.
Since there is no value, why should I hold it for a long time? Only valuable things are worth holding for a long time.
The biggest advantage of blockchain is to change the underlying organizational form of human society, slowly transforming from the current centralization to decentralization.
Talents can truly become self-aware people.
Come on, currency circle people, #虚拟货币 #区块链开发 #去中心化

It takes three years to enter the industry, five years to master it, and ten years to become the king. Trading is not about getting rich in one go, but about making reasonable profits that can be long-term, stable, sustainable, and highly probable, so that you can continuously obtain wealth. Professionalism creates value and details determine success or failure.

I will provide you with real, valuable advice to help you move forward steadily. Let’s explore, grow and create brilliance in the currency circle together!

PINAX's new 'Block Time' service - evolving from block numbers to calendar dates

Étienne Donneger will show you the 'Block Time' service, which facilitates data retrieval using a specific date instead of a block number.
The service relies on a key-value (KV) store, paired with a substream synchronization tool to pull data from substreams.
Users will benefit from multiple query options, from pinpointing block numbers by date to narrowing down to a specific date range. Simplifying access to historical data, "Block Time" provides customization for different applications.

Explore the GitHub repository to gain deeper insights and make your own block-time based service.

Layer1 blockchain Peaq will launch PEAQ tokens on CoinList from May 9 to May 16

Peaq, a Layer1 blockchain for DePIN and machine RWA, announced that it will launch its native PEAQ tokens on CoinList from May 9 to May 16, and more details will be announced soon. Users in the United States, Canada, China, South Korea and a range of other jurisdictions will not be able to participate. The token launch comes as Peaq is preparing for the mainnet launch.
Earlier in March, it was reported that Peaq completed a $15 million financing, led by Generative Ventures and Borderless Capital, and participated by Animoca Brands and others. It is reported that Peaq currently hosts more than 20 DePIN networks. The DePIN network uses blockchain technology and token incentives to build a physical infrastructure network, allowing other projects to avoid purchasing and running their own equipment. #layer1 #区块链开发 #coinlist #Depin赛道 #RWA赛道
