Bitcoin mining remains controversial - US politicians demand data on environmental pollution

 


Four members of the US House of Representatives, who also sit on the parliamentary committee on energy and economy, are demanding data from four large mining companies on electricity consumption and the resulting environmental impact of mining Bitcoin ( BTC ).


With a letter to the mining companies Core Scientific, Marathon Digital Holdings, Riot Blockchain and Stronghold Digital Mining, the four US parliamentarians Frank Pallone, Bobby Rush, Diana DeGette and Paul Tonko want to obtain the release of data for the 2021 fiscal year, leading all of them concern the power consumption of the mining centers. The aim is to break down where the electricity comes from, what proportion of it comes from renewable energies and how often the operation was suspended. In addition, the politicians want to know the average electricity costs per megawatt hour for each data center.  


"Blockchain technology has immense potential that could ensure more data protection and a more efficient economy," the politicians write in their letter to Riot CEO Jason Les. To which they add: “However, the power consumption and hardware required to run PoW cryptocurrencies [like Bitcoin] could, in some cases, create massive externalities in the form of harmful emissions and excessive e-waste.”



In recent weeks and months, criticism of Bitcoin mining - and the proof-of-work (PoW) consensus process that the market leader relies on - has become louder and louder. In the course of this, a temporary ban on PoW mining was even discussed in the US state. However, parts of the crypto industry counter that the actual environmental impact of the production of Bitcoin is completely misrepresented .

From offchain to offchain: Statechains meets Lightning

  Without a doubt, the most significant off-chain Bitcoin solution is the Lightning network. But in its wake, the statechain has emerged as an intriguing replacement. There is currently a proposal to link the two offchain networks. From an ocean, for example, you can see sunbeams glistening in the water, waves rippling, and possibly a jellyfish drifting toward the light. But you only see a small portion of it. The distance from the sea's surface to its bottom is hundreds of meters. It has dozens of different fish species swimming in it, crabs and starfish crawling on the bottom, shells clinging to rocks, and sea plants climbing up. A completely new world starts where your gaze diverges. You can picture a blockchain like Bitcoin, just like the sea. What you see on the outside is only a small portion of what is actually there; the set of UTXOs (coins) and transaction history that full nodes store are just the beginning of a much larger world. It's the plan, at least. With Bitcoin

MSP Recovery and Tokenology aim to optimize healthcare with the help of Polygon

  MSP Recovery LLC, a Miami, US-based healthcare provider with an estimated enterprise value of $32.6 billion, is partnering with Web3 company Tokenology to jointly launch a new blockchain platform called Lifechain. Lifechain wants to leverage the verifiable and transparent nature of blockchain technology to aggregate medical care claims, medical expense reports and patient data and streamline their processing. For this purpose, MSP Recovery launched its own LifeWallet in January, which already has 1 million users. In addition to the wallet and blockchain platform, an associated crypto token called LifeCoin is also used. The press release explains that the primary purpose of the system is to enable secondary healthcare providers to more effectively bill health insurance companies for their costs. “The number of medical claims tokenized going forward will surpass $50 million per day by 2024. For this we need scalability, security and sustainability, which we have only found with Polygon

Phishing attack on popular crypto sites tries to empty wallets

  Several major crypto sites such as Etherscan, CoinGecko, DeFi Pulse, and others report malicious pop-ups scammers use to try to trick users into connecting their MetaMask wallets. The phishing attack came from a domain displaying the Bored Ape Yacht Club (BAYC) logo. "We are investigating the root cause of this attack to fix the threat as soon as possible," CoinGecko founder Bobby Ong tweeted. The phishing attack appears to have been triggered by a malicious ad script from Coinzilla, a crypto ad network, according to CoinGecko. Etherscan also advises its users not to confirm any transactions that may appear on the website. The attackers attempted to use the hype around the “bored monkeys” non-fungible tokens (NFT) to gain access to the cryptocurrencies of unsuspecting website visitors. Although the websites affected by the scam attempt have reacted in the last few hours and deactivated the advertising pop-up, it is still recommended not to connect your MetaMask wallet to ne
