Harvard researchers estimated the cost of attacks on the Ethereum signal chain
Researchers at Harvard University described two strategies for attacking Ethereum 2.0’s Beacon Chain: malicious block reorganizations and deferral of finality, and also estimated their cost. Four researchers at the Harvard School of Engineering and Applied Sciences – Michael Neuder, Daniel Moroz, Rithvik Rao, and David Parkesk – have described two possible ways to attack the signal chain Ethereum 2.0. In the first strategy, an attacker can confirm the wrong block by initiating so-called “private forks”.…
