Your gateway to Bitcoin & beyond
The cryptocurrency consumes more energy than Norway. W hen bitcoin mining company Bit Digital started shipping its energy-intensive computers out of China in early , eyebrows were raised. The announcement sparked a fire sale of the computers used to power bitcoin, with mining companies scrambling to ship more than 2m of the machines out of China.
They arrived by the crateload in countries like the US, Russia and Kazakhstan. This figure keeps growing: bitcoin mining currently uses 66 times more electricity than in The threat of emergency blackouts soon led the government to permit grid operators to limit power supply to miners, leaving some facilities without power.
Even in renewable energy havens, the future of bitcoin mining is far from assured. Regulators in Sweden say that bitcoin mining siphons energy from more productive industries, and are currently lobbying the EU to ban the practice outright. But even in the free-market-loving US, an increasing number of lawmakers are souring on the industry. In theory, a greener bitcoin is possible. This is the decentralised consensus mechanism that secures the currency and prevents fraud or hacking, in the absence of oversight from banks or another centralised body.
The role of bitcoin miners is essentially to verify transactions on the blockchain. Think of bitcoin mining as a contest where miners compete to solve complex cryptographic puzzles. This ballooning energy consumption is fuelling the popularity of a less energy-intensive alternative: proof-of-stake PoS.
Kathleen Breitman, co-founder of Tezos, a blockchain platform that allows users to create and trade security tokens, says that a friend of hers ran a cryptography mailing list when bitcoin was first announced. Staking a greater number of tokens — which risk being forfeited in the event of fraud — increases the likelihood that a node will be selected by an algorithm to produce the next block of transactions, receiving rewards in the form of more tokens.
Instead of warehouses stacked high with purpose-built machines, PoS can run on a dinky Raspberry Pi microcomputer. Ethereum, the second-largest public blockchain after bitcoin, is planning to shift to PoS by the end of , and a number of new blockchain applications such as Cardano and Polkadot have chosen to launch using this protocol.
The European Commission is among the regulatory bodies trying to incentivise the industry to migrate applications from PoW to PoS but the bitcoin network has so far resisted any such move. The issue is that a majority of bitcoiners remain adamant that PoS is not a worthy replacement for PoW. Many bitcoiners believe that PoS subverts the fundamental principles of a decentralised currency that must remain outside the reach of governments and the banking system. Some bitcoiners claim that the environmental debate is overblown because energy usage will fall over the coming years.
This is because the profit miners receive for minting new coins is programmed to halve roughly every four years. Eventually, all bitcoins will be mined and miners will only receive transaction fees. In other words, shrinking rewards should shrink the pool of competing miners. The headline figure promoted at the meeting was that bitcoin accounts for only 0.
The 0. Rauchs said that the 0. Some bitcoiners argue that the cryptocurrency could incentivise a more rapid shift to renewable energy. Bitcoin mining company Marathon Digital Holdings, which runs operations in Nebraska, Texas and South Dakota, claims to have such agreements with power providers. We act like a big battery. However, bitcoin mining is not particularly unique in this regard, says Arvind Ravikumar, a petroleum researcher at the University of Texas at Austin.
And the flipside is where growing energy demands incentivise defunct fossil fuel-powered stations to come back online. Critics contend that this utility is zero, which can provoke defensiveness in its advocates.
Many allege that energy overuse is simply the latest stick with which to beat bitcoin, and that the industry is subject to unfair moral scrutiny compared to others — like gold mining or Wall Street day trading.
Ravikumar says the most important issue is what the industry is doing to reduce emissions. Illustration: Guardian Design. Reuse this content.

In this paper, we model the emergence of the Lightning Network as a bond percolation process and we explore how the distributional properties of the volume and size of transactions per user may impact its feasibility. The emergence of a connected component is studied numerically and analytically as a function of the parameters, and the phase transition separating regions in the phase space where the Lightning Network is sustainable or not is elucidated. We characterize the phase diagram determining the minimal volume of transactions that would make the Lightning Network sustainable for a given level of fees or, alternatively, the maximal cost the Lightning ecosystem may impose for a given average volume of transactions.

Bitcoin will soon be legal tender in El Salvador but much of the population in the Central American country are distrustful of the cryptocurrency and do not know how to use it, according to a poll by the Central American University UCA , a Jesuit university based in El Salvador. The survey carried out in August, questioned 1, people and found that seven out of 10 people do not fully understand what Bitcoin is. In fact, only 4. Almost 68 per cent of those surveyed said they disagree with using the cryptocurrency as a legal tender. The move follows a vote to legalise the cryptocurrency by lawmakers in June.
