What Exactly is the Ethereum Merge?

Ethereum Merge or Ethereum 2.0

The Merge has aimed to make the Ethereum Blockchain more efficient. It will switch from a proof of work (PoW) consensus mechanism to a proof of stake (PoS) system. The Mainnet of Ethereum continues to be secured by the proof of work, even while the beacon chain runs in parallel using proof of stake.
The smart contract runs into the proof of stake system, plus the full history and the current state of Ethereum, to ensure that the transition is smooth for all Ethereum holders and users.

Benefits of Merge

The consensus mechanism switch to proof of stake is expected to make Ethereum more scalable, secure, and sustainable. It will be more beneficial to Blockchain miners, thus reducing the carbon footprint and energy consumption of the Ethereum network by 99.95%
Ethereum 2.0 was the first proposal all the way back in 2016. The transaction was more complex than initially expected. Ethereum foundation lead developer Tim Beijo, indicated that the merge will happen in the few months after June of this year 2022.

Ethereum Merger will do anything with your holdings?
Nothing, it is simply a merge, there is no new token or coin that will be created. The merge only updated the consensus mechanism and improved the security and sustainability of Ethereum Blockchain.
If anyone has held an Ethereum, you don't need to do anything after the Ethereum merge launched.

Scam Alert-

Many investors were misled into thinking a new token would be issued, and scammers were capitalizing on this.
If anyone offers you a new token or link for the Ethereum Merger token, please do not click on it.
