We remind you that Ethereum is only planning to abandon Proof-of-Work, but nobody knows when it is going to happen.
This is due to the fact that Ethereum still uses Proof-of-Work and that Ethereum dApps compete for the limited resources of a single blockchain.
In the early days of a proof-of-work chain, ASIC mining is very centralized among one or two manufacturers.
Proof-of-work is a system in which everyone can validate what happened and in what order it happened.
Each node that submits a new transaction must do some proof-of-work(PoW), which determines the“own weight” of the transaction.
Hashcash is a proof-of-work algorithm invented by Adam Back, in 1997.
It was implemented in Apache's open-source SpamAssassin platform, and Microsoft gave the proof-of-work idea a spin in the incompatible“email postmark” format.
Heavy" calls in a trustless p2p network may lead to serious vulnerabilities, because nodes are obliged to check every new block's proof-of-work.
So to mitigate this, blockchain have something called proof-of-work.
It noted that digital currency systems can achieve consensus through a variety of means, including proof-of-work and trust-based consensus.

In the current implementation of Ethereum, this mechanism is established by mining based on the proof-of-work(PoW) scheme.
However, as this idea implementation demanded more time, the network was launched on the more familiar consensus model: proof-of-work.
