According to researchers, Bitcoin and Ethereum blockchains are vulnerable to Balance Attack, which encourages double spend and disrupts persistence of blockchain. The Proof of Work blockchains may have an Achilles Heel that makes them vulnerable to a “Balance Attack.” A group of researchers from the University of Sydney has published a paper offering details about this new type of attack. The Balance Attack targets the nodes with balanced mining power. By delaying the network communication between a subgroup of nodes, the attack forces double spend on proof of work blockchains like that of....
