| Presented by | | | | | 3. Throwback Thursday: the creation of Bitcoin Gold On October 24, 2017, a hard fork of Bitcoin was created. This was the second in the space of two months and produced Bitcoin Gold. On August 1, 2017, Bitcoin Cash was born. Bitcoin Gold's main purpose was to change the proof-of-work (PoW) algorithm used in mining, meaning that the process of mining couldn't run faster on specialized equipment compared to standard computer systems. In July 2018, a new mining algorithm was introduced. Prior to implementing the algorithm, Bitcoin Gold was hit by a 51 percent hashing attack in May. As a result, hackers were able to falsify the currency's ledger and steal $18 million from online exchanges. Platforms such as Bittrex later delisted it. A 51 percent attack stems from a malicious actor who is able to obtain over half of the mining power on a crypto network. In this case, those involved were able to do so by using superior computing power. | | | 9. Research shows that 42 percent of blockchain industry employees work for exchanges. The research looked at 158 companies, with nearly 7,700 people working at 30 different platforms. Out of the 158 firms, Bitmain, Coinbase, Huobi, and OKEx take the lead, with 1,500, 1,300, 1,000, and 950 people, respectively. –THE BLOCK | | | | Want to attend Odoo Connect?
