Ethereum just pulled off its final test run ahead of one of the most important events in crypto

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


Ethereum, the second-largest cryptocurrency by market value, just ran a final dress rehearsal ahead of a years-awaited upgrade that’s been billed as one of the most important events in the history of crypto.

Since its creation almost a decade ago, ethereum has been mined through a so-called proof-of-work model. It involves complex math equations that massive numbers of machines race to solve, and it requires an abundance of energy. Bitcoin mining follows a similar process.

Ethereum has been working to shift to a new model for securing the network called proof of stake. Rather than relying on energy-intensive mining, the new method requires users to leverage their existing cache of ether as a means to verify transactions and mint tokens. It uses far less power and is expected to translate into faster transactions.

The final test took place Wednesday at around 9:45 p.m. ET.

Ansgar Dietrichs, a researcher with the Ethereum Foundation, said in a tweet that the most relevant metric for success when it comes to a dry run like this is looking at time to finalization. He called it “another successful test.”

A research associate from Galaxy Digital pointed out that the participation rate after the test merge dropped, and it looked like there may have been an issue with one of the clients — but overall, it worked.

“A success Merge = chain finalizes,” Christine Kim wrote in a tweet, adding that we are likely to see similar types of issues with the upgrade on mainnet, “but the point is, the Merge worked.”

The timing of the upgrade will be discussed at a meeting of ethereum core developers on Thursday. Previous guidance indicated that the merge should go into effect in mid-September.

Ethereum’s transition has been repeatedly pushed back for the last several years. Core developers tell CNBC that the merge has been slow to progress, in order to allow sufficient time for research, development and implementation.

The price of ether, the token native to the ethereum blockchain, has been on an upswing the last month, rising nearly 80%, including a gain of 10% in the last 24 hours to around $1,875. However, it’s still down by about half this year.  

Here’s what happened

One of ethereum’s test networks, or testnets, called Goerli (named for a train station in Berlin) simulated a process identical to what the main network, or mainnet, will execute in September.

Testnets allow developers to try out new things and make necessary tweaks before the updates roll out across the main blockchain. Wednesday night’s exercise showed that the proof-of-stake validation process substantially reduces the energy necessary for verifying a block of transactions, and also proved that the merger process works.

Spotting the bugs

Tim Beiko, the coordinator for ethereum’s protocol developers, told CNBC that they typically know “within minutes” whether a test was successful. But they’ll still be looking out for many potential configuration issues in the hours and days ahead so they can quickly fix them.

“We want to see the network finalizing and having a high participation rate amongst validators and also make sure we don’t hit any unexpected bugs or issues,” said Beiko.

The easiest metric to track is participation rate, meaning how many validators are online and doing their duties, Beiko said. If the numbers go down, developers will have to figure out why.

Another key issue relates to transactions. Ethereum processes transactions in groups known as blocks. Beiko said one clear indicator the test went well will be if the blocks have actual transactions in them, and aren’t empty.

The last major check is whether the network is finalizing, meaning that more than two-thirds of validators are online and agree to the same view of the chain history. Beiko says it takes 15 minutes in normal network conditions. 

“If those three things look good, then there’s a long list of secondary stuff to check, but at that point, things are going well,” said Beiko.

Fintech Startup TradeStreet Tracking Unusual Market Events Expands Internationally

Fintech Startup TradeStreet Tracking Unusual Market Events Expands Internationally

The Swiss and Czech-based startup TradeStreet using a proprietary algorithm to track unusual stock market events is expanding its coverage from Switzerland and Czechia to the rest of Europe and the United States.

Prague, Czech Republic–(Newsfile Corp. – May 18, 2022) – TradeStreet, a Swiss and Czech-based fintech startup, is expanding its operations over the borders to foreign markets including the rest of Europe, the US and other major markets. TradeStreet is an application that helps to detect unusual events happening in the US stock market by analyzing hundreds of millions of data daily in real-time.

“We are committed to make the big market data readable to anyone,” Co-Founder and longtime investor Dominik Kovarik said. “People can go and search in millions of data in publicly or privately available data sources, but it is extremely difficult to interpret anything from them. Thus, we have founded TradeStreet. We combine data from many sources and by using modern AI algorithms we backtest, combine and interpret the results to the users.”

The platform makes it easy for intraday, swing and long-term traders to follow unusual option flows. Delivering more than 600 unusual option orders a day by scanning multiple exchanges at once, it helps stock and option traders to reveal sweep orders on the option market. That is especially helpful in conjunction with unusual trades in Dark Pool exchanges (private securities exchange in which typically large financial institutions trade anonymously).

The users will find many other features like analysis of insider transactions (CEOs, CFOs, beneficial owners and others). The AI runs big data analysis on this data based on clustering of the transactions, sentiment evolution and many more.

Similarly, one can follow analyst ratings from the top Wall Street analysts powered by AI and a set of other rules trying to filter the best analyst ratings. The proprietary algorithm, called TradeStreet Analyst Algo™, is an algorithm that based on several conditions trades based on new analyst ratings.

The platform is full of such features, and it is extremely transparent with their customers regarding future features. Via a public roadmap, it prioritizes new features directly with the users. Users can even suggest new feature ideas and by voting and they can eventually be implemented by the two development teams located in Switzerland and the Czech Republic.
