Ethereum is the world's second-biggest cryptocurrency, and it's giving bitcoin a run for its money.Ethereum is the world’s second-biggest cryptocurrency, and it’s giving bitcoin a run for its money.

A years-awaited upgrade that has been billed as one of the most important events in the history ofcryptocurrencies was just run a final dress rehearsal.

The proof-of-work model has been used to mine ether. It requires a lot of energy because of the math equations that machines are racing to solve. A similar process is followed by the digital currency.

A new model for securing the network called proof of stake is being worked on by ether. The new method requires users to use their existing cache of ether as a way to verify transactions. It is expected to translate into quicker transactions.

Looking at time to finalization is the most relevant metric for success when it comes to a dry run. He called it a success.

It looked like there was an issue with one of the clients, but overall, it worked.

Christine Kim said that we are likely to see similar types of issues with the upgrade on mainnet.

The upgrade will be a topic of discussion at the meeting. According to previous guidance, the merge should take place in September. Wednesday was the last day of the test. There is an hour and a half later.

In the last month, the price of ether has risen 80%, and in the last 24 hours it has risen 10%. It is still down by 50% this year.

Major flaws in the implementations have caused the transition to be pushed back several times. It is on track to take place in about a month, according to developers.

One of the test networks, called Goerli, is a simulation of what the main network will do in September.

Testnets allow developers to try out new things before they are rolled out across the main network. The proof-of-stake validation process can be used to verify a block of transactions and prove that the merger process works.

"Goerli has this badge of a bottom-up testnet, and I run a permissionless peer-to-peer lending platform called PWN," said Josef Je, a developer who worked with the ethereum foundation and now runs a permissionless peer-to-peer lending platform called Je said that it was the most used testnet at the moment.

The proof of stake on Goerli will be similar to the mainnet's.

Goerli is the closest to mainnet and can be used to test smart contract interactions.

Tim Beiko told CNBC that they usually know within minutes if a test was a success. They will still be looking for potential configuration issues so they can fix them quickly.

Beiko said they wanted to see the network finalized and have a high participation rate among validators.

The easiest metric to measure is the participation rate. Developers will need to figure out why the numbers are going down.

Transactions are one of the main issues. Transactions are done in blocks. If the blocks have transactions in them, and aren't empty, it will be a good sign.

More than two-thirds of validators agree to the same view of the chain history if the network is finalized. It takes 15 minutes in normal networks.

There is a long list of secondary stuff to check, but at that point things are going well.

The proof-of-stake chain on beacon is being tested by the community. Key problems have been solved by beacon.

The original proposal required validators to have 1,500 ether in order to use it. The proof-of-stake proposal requires users to have only 32 ether if they want to use it.

It is still not a trivial sum but it is more accessible.

There are a number of developments leading up to the test. The proof-of-work execution layer was merged with the proof-of-stake beacon chain. The first major dry run of the process will take place next month.

Testing the merge allowed developers to make sure the software was stable and that the network was ready for the transition.

The nearly $2 trillion wipeout is behind the scenes.
