What Hacker News says
3 sourcesFyi the Github link on this is much more interesting than the article’s overview of it [1]. What happened is that Ethermine, the largest Ethereum miner, turned on a piece of software this week that takes advantage of their position as a miner to order transactions to their advantage. They are essentially stealing from everyone else who doesn’t control 25% of ETH hashing power. But, their software is stupid, and took a shortcut.
The software Ethermine is using simulates each transaction and then reads the logs to analyze transaction profitability. They could have chosen to analyze the “opcodes” instead, but that is technically complex, and Ethermine was in a hurry to steal. So this guy created a coin that emits fake transaction events that are recorded in the logs, specifically a fake event that made Ethermine and others like them beli
