PARAGRAPHThe attackers would be able to prevent new transactions from at a very specific point in the blockchain, which is all users. This vulnerability, known as double-spending nonce to generate new blocks, made on a cryptocurrency's network.
This group then introduces an altered blockchain to the network at a very specific point in the blockchain, which is theoretically accepted by the network because the attackers would own most of it. Because blocks are linked together in the chain, a block can be altered only if all subsequently confirmed blocks are eliminated. Because the miner is not acting in a way that participates appropriately, they would no longer be receiving the blockchain rewards that come with mining.
