Balance attack on a forkable blockchain
Blockchain consensus protocols are designed to run over a network that spreads throughout the world. These protocols implement measures to protect the system from certain attacks, even when the network experiences vulnerabilities. However, there are attacks that work in certain unfavorable situations or would require the attacker to control the network. One example of this is a so-called balance attack [1].
This project consists of exploring a balance attack experimentally, using a testnet of a vulnerable protocol. Experience with systems and networking is a desired. Prior understanding of blockchain protocols is not necessary, but would be a plus.
