Ethereum successfully deployed the final network test before the Merge on the Beacon Chain. It was an extensive network test which included updating the execution and consensus layers simultaneously. This was a rehearsal of the actual merging of the mainnet and the Beacon Chain. This test impacted only testnet participants and node operators.
Update: Ethereum has now successfully implemented the Merge.
Developers of Ethereum have been adamant that the network merge will go smoothly. However, there are still some node operators who have not upgraded their clients to the merge-ready software. To make the merge more successful, these node operators should upgrade their clients to the merge-ready software.
What’s a testnet?
The testnet allowed developers to practice running nodes, deploying contracts, and experimenting with infrastructure before the final network upgrade. It also allowed developers to gauge the impact of network upgrades prior to the actual upgrade.
However, despite the many benefits, the upgrade was not without hiccups. The missed-block-rate metric was slightly higher than normal, with 0.5% of blocks experiencing failures. In addition, only 15.4% of nodes had upgraded their software before the Bellatrix upgrade.
Shadow forks
Ethereum developers recently confirmed the successful implementation of the thirteenth shadow fork, which simulated the eventual merge upgrade. Shadow forks help to ensure the network’s safety during permanent upgrades, as they stress test the network’s synchronization assumptions. After a successful shadow fork, the new system will switch to the PoS consensus mechanism.
As the transition to proof-of-stake is expected to take place between September 14th and 15th developers have been preparing the network for the change.
In April, the first network test was successfully deployed, and developers have been able to test their nodes and contracts on it. As the network transitions to proof-of-stake, the Ethereum mainnet will become faster and more energy-efficient.
Node operators have not upgraded their clients to the merge-ready software
Ethereum has successfully deployed its final network test before the Merge, but not without some hiccups. The missed-block-rate metric, which measures the frequency of blocks that fail, was 0.5% at the time of the Bellatrix upgrade, but it increased to 9% by the time the Merge went live. Ethereum developers attributed the issues to the lack of preparation on the part of node operators, who run the backbone infrastructure.
A historic upgrade
The Ethereum Merge is the biggest upgrade in the history of the cryptocurrency. A lot of testing has gone into this transition to ensure the network will remain stable throughout the transition to proof-of-stake. Next week, Ethereum developers will begin deploying the proof-of-stake consensus mechanism.
The final network test before the Merge were a crucial part of the transition process. Before the Merge, the network needed to undergo a series of tests, including a shadow fork. A shadow fork is an upgraded version of the network’s blockchain that simulates the transition from proof-of-work mining to a proof-of-stake mining model. It will also stop mining on the network.
Final thoughts
The Merge does not have certain anticipated features, such as the ability to withdraw staked ETH. Instead, proof-of-stake validators will be responsible for processing transactions and proposing blocks. The Merge will affect the entire transactional history of Ethereum. Funds are not affected by this process, but the transition to proof-of-stake will affect the issuance of ether.
Cryptocurrencies are highly volatile and great care and research should be applied before making any investment decisions. While the price of Ethereum has seen gains in recent weeks in anticipation of the Merge it is highly likely that once the Merge is complete price action may be negatively affected. This is called a “buy the rumor, sell the news” event and is quite common in both crypto and traditional markets.
