About 57% of the energy used to mine bitcoin comes from renewable sources, according to the Bitcoin Mining Council. Much of that energy comes from renewable sources. Ethereum is closer to Switzerland's 9 million citizens, eating up about 62 million terawatt hours. Bitcoin is estimated to consume about 150 terawatt hours a year, which is more electricity than 45 million people in Argentina use. As cryptographic puzzles become more complicated and more miners compete to solve them, energy expenditure soars. Though scams and hacks are common in crypto, neither the bitcoin nor ethereum blockchains themselves have been compromised in the past. The network is made up of hundreds of thousands of computers around the world, meaning bad guys would need to control 51% of the power in this vast mining pool. To overtake ethereum right now, a bad actor would need to control 51% of the network's power. For proof-of-work blockchains, that resource is power – in the form of the electricity required to run a mining operation. Every blockchain needs to run on a scarce resource, Charbonneau explained, one that bad actors can't monopolize. 'It's what's called the Sybil resistance mechanism,' said Jon Charbonneau, an analyst at Delphi Digital. This system is called 'proof of work,' and it's how both bitcoin and ethereum blockchains run.

It takes a powerful computer to have a chance in this race, and people typically set up warehouses full of rigs for this purpose.

Doing so gives you a reward: Bitcoin miners get 6.25 bitcoin ($129,000) for every block they verify, while ethereum miners get 2 ether ($2,400) plus gas, which are the fees users pay on each transaction (which can be huge). If your computer unscrambles the cryptography first, you win the right to 'validate' a block - that is, add new data to the blockchain. Your rig competes with hundreds of thousands of miners around the world trying to solve the same puzzle.

You'd set up a powerful computer - a 'mining rig' - to run software that attempts to solve complex cryptographic puzzles.

To understand the Merge, you first need to understand the role of cryptocurrency miners. Here's what you need to know to make sense of the big day. The Ethereum Mege is scheduled to occur between Sept. 'We've been working on proof of stake for about seven years now,' ethereum co-creator Vitalik Buterin said at the Eth Shanghai conference in March, 'but finally all of that work is coming together.'

The Merge is part of what in the past was called 'ether 2.0,' a series of upgrades that reshape the blockchain's foundations. Because of its technical complexity, and the increasingly large amount of money at risk, it has been delayed multiple times.

In the Merge, ethereum will adopt a system known as proof of stake, which has been planned since 2014, before the blockchain's creation.

In an era when more people than ever view climate change mitigation as society's highest priority, the carbon emissions of bitcoin and ethereum are too conspicuous to ignore.

The first point is polarizing and subjective, but the second is unequivocally true. Skeptics of cryptocurrency typically argue that coins like bitcoin and ether are useless, and that they consume enormous amounts of electricity. If it's successful, the process will lower ethereum's massive electricity requirements by over 99%. Arcane as it sounds, the Merge matters whether or not you're a blockchain believer or a crypto critic. The long-awaited Ethereum Merge is happening next week, and it's one of the most important days in cryptocurrency history.
