Ethereum has completed its last shadow fork successfully, which is a signal that the ETH network is finally ready for the merge. This merge upgrade will move the Ethereum network towards the PoS (proof of stake) mechanism.
The shadow forks were more prerequisites that were scheduled before the upgrade of the blockchain.
Shadow forks can be viewed as stress tests that help developers ensure that network will remain safe during the permanent upgrades. The first shadow fork was implemented on 11 April 2022, and the most recent shadow fork was completed after 6 months. The recent shadow fork was dubbed the Shadowfork 13 and was conducted successfully.
Ethereum developers were able to deploy contracts, run nodes, and test the network infrastructure through the test net.
The upgrade will require the community to update their ETH clients. On top of that, they will also have to run the consensus layer and the execution layer in combination.
According to the CEO of a famous crypto exchange, close attention is needed during the upgrade of Ethereum. This will ensure that no service downtime occurs along with any unintentional problem.
When cryptocurrencies were first introduced, no one was paying attention to how much energy will be consumed for the mining process. Now that cryptocurrency has been established, it is a well-known fact that a lot of energy is wasted for no reason.
That's why the 2nd most widely used cryptocurrency Ethereum is moving towards a different consensus mechanism. Under the PoS mechanism, less energy will be required for various functions of the Ethereum network. On top of that, various other changes will be introduced as well that will make the ETH better.
Considering how many people are using the Ethereum network, it has become more important to ensure zero downtime. For now, the developers are claiming that no downtime will happen and all the recent tests also confirm the same.
