Live|BitcoinABC developer: Avanche algorithm prevents 51% attack: Jinse Finance live report, Global Blockchain Developers Conference GBDC 2018 Day2 meeting is ongoing, BitcoinABC chief developer Amaury Séchet explained the 51% attack problem, 51% calculation Force secret mining. Most of the computing power is on the main chain, and many nodes enter the new chain, which is unpredictable, and many nodes will cause losses, which miners do not want to see. How to define whether this is an attack? Small reorganizations can also occur on the chain. The key is to distinguish between natural reorganizations that occur regularly and malicious reorganizations, but this is not easy to distinguish. If all nodes can randomly query nodes, if nodes randomly query and confirm, then the transaction will be more certain. We repeat this process, and we will continue to be sure whether malicious attacks have occurred. Malicious attacks are only a temporary phenomenon and cannot be sustained because they are expensive and require continuous burning of money. [2018/12/17]
