The Mystery Behind Block Time
Of all the potential implications of blockchain for the energy sector, the energy use of cryptocurrencies — and bitcoin in particular — has captured the most interest. With bitcoin value tripling in recent months and Facebook announcing its new Libra coin, interest in the energy use of cryptocurrencies is again on the rise. In this commentary, we explain why and how bitcoin uses energy; dig into published estimates of bitcoin energy use and provide our own analysis; and discuss how these trends might evolve in the coming years.
In order to understand why and how bitcoin uses energy, we first need to understand its underlying technology: blockchain.
Blockchain offers a new way to conduct and record transactions, like sending money. In a traditional exchange, central authorities e. Blockchain removes the need for a central authority and ledger; instead, the ledger is held, shared, and validated across a distributed network of computers running a particular blockchain software.
The first miner to solve the puzzle is rewarded with new bitcoins and network transaction fees. The energy use of the bitcoin network is therefore both a security feature and a side effect of relying on the ever-increasing computing power of competing miners to validate transactions through PoW.
The energy use of the bitcoin network is a function of a few inter-related factors some of which respond to the changing price of bitcoin :. The rising price of bitcoin, particularly as it rose to all-time highs in December , drove huge increases in hashrate and difficulty, and the development and deployment of more powerful and energy efficient mining hardware. The IT infrastructure for bitcoin and other cryptocurrencies has evolved rapidly over the past decade. In the early days of bitcoin , hobbyists used standard central processing units CPUs to mine bitcoin.
By October , miners started to use more powerful graphics processing units GPUs as mining difficulty increased. By June , miners — increasingly large and more industrial operations — used more powerful but less energy-efficient field-programmable gate array FPGA hardware, and a year later, moved to application-specific integrated circuits ASICs.
ASICs are purpose-built chips, in this case, to mine bitcoin. Diverse methodologies , limited data availability, and highly variable conditions across the industry e. Therefore, all estimates must be interpreted with caution. These figures can appear large when compared to countries like Ireland 26 TWh or emerging technologies like electric vehicles 58 TWh in , but small when compared to other end-uses like cooling 2 TWh in Nonetheless, bitcoin mining is a highly mobile industry, allowing it to migrate quickly to areas with cheap electricity.
Localised hotspots and electricity supply issues can emerge quickly, generating strong backlash from regulators and the public. Bitcoin has also been compared on a per-transaction basis to VISA payments , the broader banking system, and gold mining. However, comparisons on a per-transaction basis are not meaningful in the context of PoW blockchains , particularly because the energy required for the networks to function is independent of the number of processed transactions.
These key assumptions have been criticised to overestimate electricity consumption; indeed, BECI estimates represent the high range of published estimates to date. They also conduct sensitivity analyses around key uncertainties, including electricity costs and capital depreciation schedules.
Under their central assumptions, they estimate that the bitcoin network consumes between 35 TWh May and 41 TWh November ; June per year. Other researchers have calculated lower-bound estimates using a bottom-up approach e. The Bitmain Antminer S9 series 0. Using this approach, we can estimate that thebitcoin network excluding cooling consumed 31 TWh in Therefore, we estimate that bitcoin mining consumed around 45 TWh in , which aligns well with the latest peer-reviewed estimate of With the recent run up in price and hashrate, energy consumption is expected to be much higher in Through the first six months of , bitcoin mining has already consumed an estimated 29 TWh.
While these early estimates provide a rough indication of bitcoin energy use today, it is clear that researchers need more data, in particular from mining facilities , to develop more rigorous methodologies and accurate estimates.
Headlines concerning the environmental impacts of bitcoin re-emerged last October, when a commentary article from Mora et al. Crucially, the use of country average and in some cases, world average emissions factors inflates the GHG estimates, since bitcoin mines are typically concentrated in renewables-rich states and provinces.
Indeed, the selection of mining locations depend on a balance of several key factors , including access to low-cost electricity, fast internet connections, cool climates, and favourable regulatory environments. These mining facilities may be absorbing overcapacity in some of these regions, using renewable energy that would otherwise be unused , given difficulties in matching these rich wind and hydro resources with demand centres on the coast.
Another analysis of data from 93 mining facilities representing 1. Since then, researchers have collected real-world data and developed and refined methodologies to establish rigorous estimates of the energy use of data centres and the global ICT sector , including by the IEA. The dire predictions about the energy use of the internet failed to materialise despite exponential growth in internet services, largely because of rapid improvements in the energy efficiency of computing and data transmission networks.
The outlook for bitcoin energy use is highly uncertain, hinging on efficiency improvements in hardware, bitcoin price trends , and regulatory restrictions on bitcoin mining or use in key markets. It is important to recognise that bitcoin is just one cryptocurrency, which is one application of blockchain, which is itself one example of distributed ledger technology DLT. Ethereum ETH , the second largest cryptocurrency by market value, processes more than twice as many transactions as the bitcoin network while using only about one-third of the electricity consumed by bitcoin.
Other DLTs like Tangle and Hashgraph similarly offer the promise of lower energy use, scalability, faster transactions, and no transaction fees compared to blockchain.
Over the coming years, other applications of blockchain — including those within the energy sector — are likely to garner more attention. As the scope and scale of blockchain applications increases, these trends combined are likely to materially reduce the future energy footprint of its technology.
That said, this is a very dynamic area that certainly requires careful monitoring and rigorous analysis — particularly, a careful monitoring of local hotspots. The energy use of bitcoin and blockchain is just part of the blockchain and energy story. Thank you for subscribing.

How are Bitcoin’s Difficulty and Hash Rate Calculated?
Abstract: This piece contrasts mining economics between Bitcoin and traditional resource mining. We look at how the difficulty adjustment can impact profitability in the mining industry and some potentially perverse incentives. Mining is the random process by which new Bitcoin blocks are found, such that transactions are confirmed. This is a necessarily competitive and energy intensive process. In order to ensure a smooth and reliable network, every two weeks, based on how many blocks were mined in the period, the mining difficulty adjusts. There is an average target interval between blocks of 10 minutes.
Mining Difficulty Explained
Industry leaders in transparency and innovation, with more than 1. Cutting-edge firmware with an implementation of Stratum V2 and mining software written from scratch in Rust language. Quality improvements including reduced data loads, empty block elimination, hashrate hijacking prevention, and more. Bitcoin mining and difficulty adjustments explained in non-technical terms using a simple dice analogy. Most people misunderstand what bitcoin miners actually do, and as a result they don't fully grasp the level of security provided by bitcoin's hashrate. Simply put, mining is a lottery to create new blocks in the Bitcoin blockchain. There are two main purposes for mining:.
Mining pool
Cryptocurrency mining is a very fancy word for those who don't know the difficulties faced by miners. We have often heard about miners coming up with a powerful hardware setup to tackle the mining difficulties. It does need powerful machines, the perfect software, electricity, and a mining pool. This might be strange for people who are new to cryptocurrency mining.

Mining Difficulty Expected to Increase for the First Time Since China Crackdown
Bitcoin mining a block is difficult because the SHA hash of a block's header must be lower than or equal to the target in order for the block to be accepted by the network. This problem can be simplified for explanation purposes: The hash of a block must start with a certain number of zeros. The probability of calculating a hash that starts with many zeros is very low, therefore many attempts must be made. In order to generate a new hash each round, a nonce is incremented.
An easy look at difficulty. When mining bitcoin , one of the key factors in determining success is the difficulty. As a Proof-of-Work-based cryptocurrency, crypto miners contribute hashpower in a race to solve complex puzzles required to secure each bitcoin block. Bitcoin mining difficulty is an indicator of how hard it will be to mine a BTC block. For individual miners or pools , a higher difficulty means more hashpower is needed to be in with a chance of gaining block rewards. Bitcoin's difficulty last changed to

What is pushing mining difficulty upward?
What is the mining difficulty and Hash rate and how does it affect my returns when mining crypto currency? It was challenging for me to understand the principles of the crypto-currency networks, but I took a lot of time and effort, reading and research to understand it, so I decided to share my perspective on the mining difficulty debate. The difficulty can change. It depends on the Hash Rate of the network the number of miners who are mining the network.
