As the 2nd tweet explains, the difficulty of Ethereum changes dynamically amd can decrease the longer that a block hasnt been mined, this is not the case in Bitcoin.
- infthi 4y agoBitcoin also adjust difficulty - but does that every two weeks or so. would it make sense to mine for a sibling for the last block before the difficulty increase while everyone else mines for a child block with increased difficulty? thus having twice the relative hashrate for 10 min every time difficulty increases.
- game-of-throws 4y agoNo, this attack wouldn't work on bitcoin. Bitcoin chooses the chain with the most total work (which is blocks x difficulty), not the most blocks. Else someone could fork the chain from a block sometime in 2009 when difficulty was very low and outpace the rest of the network.
- shakezula 4y agoThis is not true. Bitcoin has a difficulty adjustment. https://www.blockchain.com/charts/difficulty https://www.blockchain.com/charts/difficulty https://www.coindesk.com/learn/bitcoin-mining-difficulty-everything-you-need-to-know/ https://www.coindesk.com/learn/bitcoin-mining-difficulty-eve...
- mw888 4y agoIt was true, but they didn’t specify that Bitcoin adjusts difficulty when the new block is published, not ever while waiting for a block.
