Chinese Internet Celebrity Explains Bitcoin, Blockchain Technology to Over 500,000 Viewers

A Chinese internet celebrity called Li Yongle (李永乐) has recently made a 15-minute long video where he tried to explain to his followers what bitcoin and blockchain technology are. The video reportedly went viral in the country.

According to local news outlet 8BTC, Yongle has over 900,000 followers on a popular Chinese video-sharing platform, 2.8 million followers on the country’s version of Twitter, Weibo, and over 270,000 subscribers on YouTube.

This, as he is a well-known math and physics teacher in China, that helps others understand complex topics by simplifying them. The video of him explaining bitcoin and blockchain technology, which has also been shared on YouTube, is said to have been viewed over half a million times, and racked up over 5,000 comments.

The video went viral, according to 8BTC, thanks to key opinion leaders in the Chinese community, who helped spread the word by retweeting it. Among the 5,000 comments were viewers trying to learn more, asking how they can use bitcoin with their bank accounts, or whether or not mining the cryptocurrency consumes huge amounts of energy.

While the Chinese government has in the past cracked down on cryptocurrencies, state-run publications reportedly often share Li Yongle’s work. Other Chinese celebrities have reportedly already promoted bitcoin and cryptocurrencies on their shows.

Chinese cryptocurrency billionaire Zhao Dong has, back in November of 2018, predicted bitcoin could hit $50,000 within three years. Per his words, the right time to buy bitcoin is during the bear market, as those who “make truckloads of money do not have a very short-term speculative driven investment mindset.”

Notably, China’s central bank, the People’s Bank of China (PBoC), has late last year said security token offerings (STOs) are illegal in the country, reinforcing its attitude towards the nascent sector. Despite the central bank’s attitude, a Chinese court has ruled that cryptocurrencies like bitcoin should be protected by law.

Error in Time-Locked Bitcoin Contracts Allows for Miner 'Fee-Sniping'

  • Crypto researcher 0xb10c discovered an error in bitcoin "time-locked" transactions that could be used as an attack vector.
  • Miners can take advantage of the program to carry out "fee-sniping" and steal funds from one another. 

Users have discovered an error in bitcoin “timelocked” contracts that could potentially allow miners to steal BTC from one another. 

Anonymous crypto engineer 0xb10c reported discovering more than one million “time-locked” transactions made between September 2019 and March 2020. In a post, 0xb10c detailed how these special bitcoin transactions were not being accurately enforced by the network. 

As opposed to normal transactions, time-locked transactions prevent recipient bitcoin from being accessed after sending. Users must wait for a specific number of blocks to be added to the network in ten-minute intervals before gaining control of their bitcoin. 

0xb10c claimed the errant time-locked transactions provided an attack vector for miners to steal transaction fees  from one another via “fee-sniping.” According to the engineer, the backlog of time-locked transactions were being purposefully designed for a “potentially disruptive mining strategy” involving the theft of miner fees. 

In an interview with CoinDesk, 0xb10c said time-locked transactions represented a “low-priority” problem at present that could eventually balloon to involve the wider network. He explained that fee-sniping would become more lucrative in a few years as the majority of miner income shifts towards transaction fees. 

He continued, 

A fix for this has been released in early 2020. However, it will take a while before all instances of the currently deployed software are upgraded.
