The week began with the news of a 51% attack on the Ethereum Classic network, which the attackers purportedly executed undetected over several days. The attackers managed to pocket the US $5.6 million through double-spending. The network was attacked again on Thursday, with the attackers ripping off US $1.6 million. The attackers were able to mount up sufficient resources for the attack by spending a mere 17.5 Bitcoins worth US $192,000 for renting the required hash power. This news and many more in this week’s newsletter.
Ethereum Attacked – Twice
Last Saturday, the Ethereum Classic network suffered the infamous 51% attack. Initially, it was assumed to be innocuous, surmised to be a miner using an old software unintentionally. However, such assumptions soon proved incorrect, and it turned out to be a thorough-planned and well-executed attack in which the attackers made away with approximately US $5.6 million after reorganizing 4,280 blocks over four days. The next attack occurred on Thursday when the attackers managed to reorganize 4,236 blocks before making away with US $1.6 million.
The core team is considering several measures to mitigate the problem, including increasing the transaction confirmation times and even contemplating on switching to Proof-of-Stake consensus.
Ethereum 2.0 Testnet Live
Meanwhile, according to the Ethereum Foundation, the official testnet of Ethereum 2.0, Medella, is live. This network has around 20,000 validators who have staked 650,000 Ethers cumulatively. One of the significant changes in Ethereum 2.0, is the switching of the consensus mechanism from resource-intensive Proof-of-Work to Proof-of-Stake.
However, the launch of the testnet did not go as expected. Only 57 percent of the validators participated during the launch. Instead of the expected 80 percent, only 57 percent of the stake was used to validate the network. Additionally, the Ethereum Foundation is planning a dedicated security team for Ethereum 2.0. The team will study any potential cybersecurity and crypto-economic issues in the next generation of the Ethereum network.
US love-and-hate relationship with Blockchain
Earlier this year, a bill to create verifiable health records on the Blockchain was proposed in the California legislation. The aim was to help slow the infection rate while keeping people with a high health risk safe. However, the digital rights group, Electronic Frontier Foundation (EEF), considers this bill as a significant privacy breach. According to EEF, putting sensitive information such as health records on Blockchain makes it easier for perpetrators to track citizens.
Meanwhile, the US Securities and Exchange Commission (SEC) is also growing an interest in cryptocurrencies. On Thursday, the US Senate voted in Hester Peirce for a second term as commissioner in SEC. Ms. Peirce, fondly addressed as Crypto Mom for her support for crypto projects, will remain in her post until 2025. Additionally, the SEC is looking to procure a blockchain forensics tool that can analyze smart contracts for security issues and vulnerabilities.
Russia’s Blockchain week
In Russia, it was a mixed bag for Blockchain. Earlier this week, reports emerged, suggesting that over personal information of over 1.1 million Russians who voted electronically in the last election were stolen. In the elections held last month to vote on constitutional amendments, Russian voters were allowed to vote electronically using Blockchain technology. The voters’ data breach is another addition to the numerous issues that have riddled this election process, casting doubts on the efficacy of Blockchain in voting systems.
Contrarily, shortly after the Russian’s President, Vladimir Putin, signed the cryptocurrency laws, Sberbank, the country’s largest bank, made a few promising announcements.
