The switch to PoS on Ethereum is now being tested on a mainnet shadow split

On Tuesday, a shadow fork of the Ethereum mainnet went live, taking it one step closer to the Ethereum 2.0 upgrade's move from proof of work (PoW) to proof-of-stake (PoS) consensus method.

The Ethereum Foundation is working on a multi-stage migration to the PoS algorithm, which will allow validators to create blocks instead of mining by staking assets.

Developers can use a shadow fork to test upgrades before putting them on the mainnet.

The switch to the PoS consensus mechanism is expected to significantly reduce energy consumption and improve Ethereum's scalability.

The Beacon Chain, the first stage of the Ethereum 2.0 upgrade, went online in December of last year, with The Merge, the second stage, projected to be finished by June or early in the third quarter of 2022.

The shadow fork explorer site was offline at 12:00 Asia time on Tuesday, but by early morning, the network had completed 1.8 million transactions with an average block creation time of 13.8 seconds.
