1/ we have new participants entering #Ethereum, first from #DeFi, but increasingly from #NFTs
many highlight concerns on energy consumption from Proof of Work blockchains like #Ethereum & #Bitcoin

many highlight concerns on energy consumption from Proof of Work blockchains like #Ethereum & #Bitcoin
let& #39;s talk about it, and how we& #39;ll move past it in #Ethereum Proof of Stake
2/ first, it takes a tremendous amount of energy to secure a Proof of Work (PoW) blockchain
PoW blockchains are secured by computers (mostly graphics cards and specialized hardware known as "ASICS") from "miners," solving a work-intensive math problem for every block produced

3/ the total "miner" contribution of this energy/computational power is known as "hashrate"
the "winning" miner who solves each new math problem first gets to produce the next block, and receives a block reward (in ETH, BTC, etc.) and any fees paid by users within that block

4/ to be most secure, you want as much hashrate as possible from as many sources as possible
in PoW, the hardware & electricity become something miners "put at stake" in PoW
this ensures honest behavior and is critical for the operation of a decentralized PoW network

5/ if they are found to have been dishonest in that block production, the network will revert their block and the miner will lose their block reward- in effect wasting their electricity
this creates an important financial incentive for honest behavior

6/ we can debate if this energy for PoW mining is "wasted" (as it is used for a productive purpose)
but we may agree that it is sub-optimal, and perhaps there is a better way

7/ in Ethereum 2.0 (eth2), the Proof of Stake (PoS) upgrade for #Ethereum,
rather than staking electricity to produce a block, block producers instead stake their $ETH
this shifts the security model from energy expenditure to collateral-based economic security

8/ yes, computers will still secure the network, BUT there will be no more complex math problems to solve, and no electricity to be staked
thousands of computers, using the power of a consumer laptop, can get the job done- versus energy-intensive industrial mining rigs

9/ the economic incentive for honest block production is the staked $ETH each block producer must lock
each validating node must put up 32 $ETH as "stake"
if they misbehave, those holdings can be "slashed"
this may prove to be even more effective at securing Ethereum than PoW

10/ so while #Ethereum PoW energy consumption remains high, the entire community is laser focused on transitioning to eth2 / full Proof of Stake
when will this happen? well, the first part of eth2 is already live, with 3.3 million $ETH committed / "bonded" to staking nodeshttps://abs.twimg.com/emoji/v2/... draggable="false" alt="😲" title="Erstauntes Gesicht" aria-label="Emoji: Erstauntes Gesicht">

11/ we expect that the merge/transition to Proof of Stake will happen within the next 1 to 2 years
so no, while current PoW energy consumption is not ideal, we will fix it
and our community & brightest minds won& #39;t rest until #Ethereum is a green blockchainhttps://abs.twimg.com/emoji/v2/... draggable="false" alt="🌳" title="Laubbaum" aria-label="Emoji: Laubbaum">https://abs.twimg.com/emoji/v2/... draggable="false" alt="🌍" title="Europa-Afrika auf dem Globus" aria-label="Emoji: Europa-Afrika auf dem Globus">
