All of the smart contracts, coins, and NFTs that exist on the current chain would be automatically duplicated on the forked, or copied chain. If a node validates bad transactions or blocks, the validators face “slashing,” which means all their ether are “burned.” (When coins are burned, they are sent to an unusable wallet address where nobody has access to the key, rendering them effectively useless forever.)Īs Ethereum transitions to its new protocol, another risk is that a group of disgruntled miners could decide to create a competing chain. The more you stake, the greater your chance of “winning the lottery.” If you’re chosen and your block is accepted by a committee of “attestors”-a group of validators randomly chosen by an algorithm-you are awarded newly minted ether.Įthereum’s proponents claim that a key advantage proof of stake offers over proof of work is an economic incentive to play by the rules. If you don’t have that kind of spare change on hand, and not many people do, you can join a staking service where participants serve as validators jointly.Īn algorithm selects from a pool of validators based on the amount of funds they have locked up. In the proof-of-stake system Ethereum is slowly moving to, you put up 32 ether-currently worth $100,000-to become a validator. But as Buterin noted in 2014, developing such a system was “so non-trivial that some even consider it impossible.” So Ethereum launched with a proof-of-work model instead, and set to work developing a proof-of-stake algorithm. In fact, it was supposed to be the mechanism securing Ethereum from the start, according to the white paper that initially described the new blockchain in 2013. Proof of stake, first proposed on an online forum called BitcoinTalk on July 11, 2011, has been one of the more popular alternatives. Since early on in Bitcoin’s history, though, crypto enthusiasts have searched for other consensus mechanisms that can preserve some degree of decentralization-and aren’t as wasteful and destructive to the planet as proof of work. In the case of Bitcoin, this ended up putting a handful of big companies in control of the network. Any system that uses proof of work will naturally re-centralize. This works against the concept of decentralization. And the larger the mining operation, the larger their cost savings, and thus, the greater their market share. Sprawling server farms around the globe are dedicated entirely to just that, throwing out trillions of guesses a second.

That’s because building such a model is complex. “ it would take one year to POS … but it actually taken around six years,” Ethereum’s founder, Vitalik Buterin, told Fortune in May 2021. Of course, Ethereum’s move to proof of stake has been six months away for years now.

Sometime in the first half of 2022, in a dramatic event termed “ The Merge,” Ethereum plans to transition its entire network to a different consensus mechanism: proof of stake, which it promises will use 99% less energy, allow the network to scale, and potentially help it reach 100,000 transactions per second. With all the money venture capital firms are shoveling into Web3-a futuristic model where apps will all run on decentralized blockchains, much of it powered by Ethereum itself-now is a good time for Ethereum to disassociate from proof-of-work mining. CryptoKitties, a game where players breed and trade cartoon cats, caused a transaction pileup on the network in 2017.

Ethereum’s mechanism has other drawbacks-it’s tediously slow, averaging 15 transactions per second.
