New blockchain service refuses to attack BDoS and is proposed to attack BTC at only 20% hash power cost

According to Medium, researchers from Cornell University and the Cryptocurrency and Contract Initiative (IC3) have jointly proposed a new type of blockchain attack in the paper "BDoS: Blockchain Denial of Service", which can destroy The economic motivation in the blockchain has led to rational miners stopping mining. This new type of attack, known as the Blockchain Denial of Service (BDoS), can perform a service denial of attack on a blockchain similar to Bitcoin, and the cost is much lower than the 51% attack cost. Requires 20% attack cost.
