imageThus the result is determined by the combination of the server and client codes. In the turn from the customer side is also sent a random number from 1 to 100, which will determine the number of a cell to open.

Bitcoin miners initially used general-purpose computers, but they quickly switched to more dedicated hardware that offered higher performance (in terms of hash rate R , measured in the number of hashes ( h ) computed per second) at lower. For each block mined, the miner receives a block reward as well as the transaction fees of the transactions in the block. As bitcoin gained in popularity, an arms race started among miners. Bitcoin mining is attractive since it offers a strong financial incentive.

In other words, the outcome of the roll of the dices will always be formed based not only on the internal system of mixing numbers, but also on an external factor, which excludes the possibility of manipulation.

Our focus in this review is on sustainability in the context of environmental and economical aspects. We try to answer the question whether the bitcoin system is sustainable given the energy consumption required for bitcoin mining, which has been subject of debate in the last few years. Bitcoin may pose risks to the stability of the current financial system, while also lack of controls over bitcoin exchanges and the volatility of the bitcoin currency raises concerns. The contributions of this paper are: firstly, to synthesize and critically assess the viewpoints in scientific literature; and finally, to argue that the energy consumption of the bitcoin system is not excessive, which stands in contrast to the public opinion that bitcoin mining is a gross waste of energy. We explore four subquestions: What factors play a role in the energy consumption of bitcoin mining, how large is this energy consumption, does this impede sustainability, and if so are there alternatives that can reduce energy consumption? In the following sections we outline the basic operation of the bitcoin system, we summarize trends in the hardware used for bitcoin mining, we discuss the energy footprint of bitcoin mining, we present some of the alternatives that have been proposed to reduce energy consumption, and we briefly discuss other applications of the blockchain technology that is at the basis of the bitcoin system. The sustainability of bitcoin is depending on a mix of environmental [10••, 11••], economical [1, 12], financial [2, 13, 14] and ethical [15] aspects. In this review paper we provide an overview and synthesis of recent literature published in the last two years that addresses the sustainability of bitcoin.

But the gradual mainstreaming of digital currency, the investment by prominent technology people, and the experimentation with blockchain by most of the world’s largest financial institutions has mostly lifted that cloud of suspicion, particularly as Bitcoin payments become accepted by more and more mainstream retailers, BNB both online and offline.

Bitcoin is now worth quite a bit more than a few cents, rising as high as $20,000 per single coin in December 2017. It has since declined in price from that lofty level, and is extremely volatile in terms of value, jumping hundreds of dollars in a day or declining an equal amount.

There is no central server or point of control, and all nodes in the network are equal peers. The bitcoin system is a distributed, peer-to-peer network. The blockchain contains the entire history of bitcoin transactions. Each transaction to transfer an amount of bitcoins among users is transmitted to the bitcoin network where it is stored in a distributed transaction ledger, the blockchain. Each node in the network stores a (complete or partial) copy of the blockchain.

In addition to the agreement on the block order, a consensus is also required for implying updates to the state of the blockchain, namely either account balances or memory accessed by smart contracts. The new block is determined as a selection of transactions among the pool of pending transactions, namely transactions that have been issued by one of the participants but do not yet appear in the blockchain. The block selection process implies an order on the transactions. Typically, participants reach an agreement on the blockchain content through an agreed-upon addition of a new block.image
