Simulating fraudolent mining strategies in a simplified Bitcoin Network

ثبت نشده
چکیده

The goal of the project is the evaluation of the Bitcoin mining process, through its simulation in TinyCoin, a simplified version of Bitcoin. In particular, it is required to consider one or more fraudolent versions of the mining process and to compare them with the standard mining process/between themselves. In TinyCoin, each user has a single address and the transactions are simplified with respect to Bitcoin as follows:

In the context of the ‘selfish-mine’ strategy proposed by Eyal and Sirer, we study the effect of propagation delay on the evolution of the Bitcoin blockchain. First, we use a simplified Markov model that tracks the contrasting states of belief about the blockchain of a small pool of miners and the ‘rest of the community’ to establish that the use of block-hiding strategies, such as selfish-mine...

On the Phase Space of Block-Hiding Strategies in Bitcoin-like networks

We calculate the probability of success of block-hiding mining strategies in Bitcoin-like networks. These strategies involve building a secret branch of the block-tree and publishing it opportunistically, aiming to replace the top of the main branch and rip the reward associated with the secretly mined blocks. We identify two types of block-hiding strategies and chart the parameter space where ...
