Bitcoin Mining Pools A Cooperative Game Theoretic Analysis

We examine dynamics of pooled mining and the rewards that pools manage to collect and use cooperative game the-oretic tools to analyze how pool members may share these rewards. A cooperative game theoretic analysis.

In the second game we consider K opportunities each of which corresponding to another blockchain.

Bitcoin mining pools a cooperative game theoretic analysis

. A bitcoin is created by miners using complex mathematical proof of work procedure by computing hashes. Each pool has a designated pool supervisor or operator who then distributes the earned rewards. Request PDF Bitcoin Mining Pools.

If someone has 51 of the mining power they control the blockchain and effectively have the power to alter it at will enabling them for example to spend the same bitcoins twice. Although mining pools smooth out Bitcoin rewards and make it more predictable for an individual miner they concentrate power to the pools operator. 2015 Bitcoin mining pools.

Zohar and Rosenschein JS. We develop a game-theoretic model that allows us to capture short-term as well as long-term impacts of attacks against mining pools. Bitcoin is an innovative decentralized cryptocurrency whose core security relies on a proof of work procedure which requires network participants to repeatedly compute hashes on inputs from a large search space.

We show that for some network parameters es-pecially under high transaction loads it is difficult or even impossible to distribute rewards in a stable way. We denote by N 1 2 N the set of miners also referred to as users. Some participants are always incentivized to switch between pools.

Mining pools are groups of cooperating miners who agree to share block rewards in proportion to their contributed mining hash power. On mining pools threaten the long-term viability of Bitcoin. We develop a game-theoretic model that allows us to capture short-term as well as long-term impacts of attacks against mining pools.

While mining is the only way that new bitcoins come into existence the real purpose of mining is to confirm transactions and add them to the blockchain. We examine dynamics of pooled mining and the rewards that pools manage to collect and use cooperative game the-oretic tools to analyze how pool members may share these rewards. Blockchain Competition Game 31.

In Proceedings of the 2015 International Conference on Autonomous Agents and Multiagent Systems. Our study addresses the trade-o between two di erent investment dimen-sions in the context of Bitcoin creation. At each time slot of durationT which corresponds to a new puzzle to be.

While mining pools are desirable to the average miner as they smooth out rewards and make them more predictable they unfortunately concentrate power to the mining pools owner. There are multiple huge mining pools and each of them may possess up to 30 of the total computation power of the Bitcoin network the same applies to some other altcoins. Using this model we study the conditions under which the mining pools have no incentives to launch attacks against each other ie peaceful equilibria and the conditions under which one mining pool is marginalized by at-tacks ie one-sided attack equilibria.

Bitcoin pools are a direct example of competitive distributed computation. Mining pools are slightly better at coordinating participants due to lower-latency communication a fact which implies that they man-age to collect slightly higher rewards. A peer-to-peer electronic cash system.

A Game Theoretic Analysis.

Bitcoin Mining Pools. We show that for some network parameters especially under high transaction loads it is difficult or even impossible to distribute rewards in a stable way. A Cooperative Game Theoretic Analysis.

Using this model we study the conditions under which the mining pools have no incentives to launch attacks against each other ie peaceful equilibria. A Cooperative Game Theoretic Analysis. This can be viewed as the CPS game.

In the first game there is a single blockchain eg cryptocurrency and any of theM ESPs or mining pools can be used by the miners to solve the puzzle. We develop a game-theoretic model that allows us to capture short-term as well as long-term impacts of attacks against mining pools. Finding one of the rare inputs that generates an extremely low hash value is.

In each round of mining which roughly takes 10 minutes pools compete to solve the puzzle and the ﬁrst one to solve claims a set of newly minted Bitcoins. There is a finite population of miners and if a miner changes his strategy this will cause a change in. Some par-ticipants are always incentivized to switch between pools.

Miners mining servers and puzzlesWe consider a population of M ESPs and a set of K cryptocurrencies where each cryptocurrency is associated to its blockchain. Bitcoin is a decentralized cryptocurrency payment system working without a single administrator or a third party bank. Finding one of the rare inputs that generates an extremely low hash value.
