After a major tech upgrade, the world's second-largest cryptocurrency Ethereum has gained more than 25 per cent in a week. Crypto analysts say the London Hard Fork update is the reason behind the surge in the cryptocurrency's value. The update has nothing to do with London. A hard fork means an unchangeable permanent modification on the blockchain platform. Forks are major technical upgrades or changes made to the blockchain network — they typically stem from Ethereum Improvement Proposals EIPs and change the "rules" of the protocol.

Cryptocurrency Ethereum hits record high ahead of CME futures launch
September was a rough month for crypto investors, in particular for those betting big on ether, the token tied to the ethereum blockchain.
It's difficult to link short-term price movements to any specific event, and with the historic rally in crypto over the past 12 months, pullbacks are to be expected. Investors are now buying the September dip. But the September roller-coaster reflects a particularly rocky stretch for the ethereum ecosystem, which has given investors and developers reasons for concern.
The speed of the network and high transaction fees continue to be a problem. The "London" upgrade in August was supposed to make transaction fees less volatile , but it's had a limited effect. Meanwhile, rival blockchains dubbed "ethereum killers" are taking advantage of ethereum's challenges.
Ethereum also unexpectedly split into two separate chains in late August, after someone exploited a bug in the software that most people use to connect to the blockchain. That exposed the network to an attack, and not for the first time. So I wouldn't try to read too deeply into these short-term movements. Still, ethereum, which serves as the primary building block for all sorts of crypto projects, like non-fungible tokens NFTs , smart contracts and decentralized finance DeFi , has some major hurdles to overcome to fend off the emerging competition.
A central premise of ethereum's security stems from the existence of only one set of virtual books, meaning you can't create coins out of thin air. That ledger has to work, because the decentralized nature of the blockchain means there's no rule keeper or bank that sits in the middle of transactions to act as accountant.
With rising rates and inflation, investors are split on how to value bitcoin. Stocks that are inflation plays are moving closely with cryptocurrency, Trivariate Research found. For a while, it was unclear whether the split would lead to a "double-spend attack," where the same token can be spent more than once and transactions can be reversed, Hougan said. Smart contracts overseeing billions of dollars in assets could have also been at risk. Smart contracts allow people to build applications on top of ethereum with self-executing code, eliminating the need of third parties to handle transactions.
Such an attack would have been difficult to execute, since it was clear which nodes were on the correct side of the split and which were not. The good news for miners and exchanges is that most of them upgraded their software as recommended and the issue was resolved relatively quickly, said Tim Beiko, the coordinator for ethereum's protocol developers. Auston Bunsen , co-founder of QuikNode, which provides blockchain infrastructure to developers and companies, said it was a "responsibly disclosed vulnerability.
In April, the ethereum blockchain was hit with a bug in one of the software programs used to access it. And in November, many of ethereum's DeFi apps temporarily went down after a Geth upgrade debacle, which led to the chain splitting in two.
Geth is short for for Go Ethereum. To access the ethereum blockchain, operators and miners have their pick of software. When the ethereum blockchain broke in half a few weeks ago, it was because Geth had a bug in its consensus mechanism. That's what creates the single source of truth for transactions so everyone sees the same thing regardless of what software they're using. Developers discovered the bug, put out a new release with a fix and publicly told everyone to update. A lot of users upgraded, but others didn't.
When an unknown actor exploited the bug, ethereum forked, meaning that it broke into two separate chains: one for those who had updated their software and one for those who had not. Ethereum "sought the veneer of decentralization by having many clients, but as a consequence, they have incompatibilities," said Nic Carter, co-founder of blockchain data aggregator Coinmetrics.
Bitcoin takes a very different approach. It relies on a highly secure software program for nodes to access the blockchain. Bitcoin developers have long sought to avoid hard forks at all costs, so all changes in the core software tend to be opt in rather than pushed out to users, according to Carter.
Some crypto experts attribute ethereum's success to its first-mover advantage. Launched last year, Solana is gaining traction in the NFT and DeFi ecosystems because it's cheaper and faster to use than ethereum.
Ethereum can only handle roughly 13 transactions per second and transaction fees are substantially more expensive than on Solana. Institutional money is flowing. Investors who had been largely focused on ethereum "have been increasingly diversifying their holdings to other cryptocurrencies, fueling alternative blockchains like Algorand, Solana and Cardano," said Mark Peikin , CEO of Bespoke Growth Partners.
Bunsen tells CNBC that while Solana is making good strides in terms of being a usable blockchain, it's not yet decentralized enough to satisfy the larger crypto community.
It's also not immune to bugs. Last month, Solana suffered a hour outage following a denial-of-service attack, which took the form of a flood of transactions caused by bots. The list of so-called ethereum killers is long, and includes blockchains like Matic and Polygon, which are complementary to ethereum, according to Bunsen, as well Cardano, which is known for its security.
Ethereum also has its own upgrade in the works. For several years, it's been building ethereum 2. The makeover will move ethereum to a less energy-intensive mining process and, according to network founder Vitalik Buterin , could boost speed by over 7,fold to , transactions per second. If it's successful, Bunsen said, ethereum 2. Skip Navigation.

Ethereum developers were rightly alarmed in August when the chain split because of a bug. VIDEO The longer-term problem for ethereum is that random glitches like this keep happening. When the software programs don't talk to one another, it creates problems for the network. That's starting to change, thanks to the growing popularity of rival blockchains.

Ethereum cryptocurrency to slash carbon emissions
Bitcoin declined to its lowest level in six months on Monday as the crypto sell-off continued with investors moving away from risky bets. Bitcoin, the biggest cryptocurrency, which was trading at 33, — lowest since July 24, — had plunged nearly 22 per cent in the past seven days while altcoins also registered a steep decline. Ethereum dropped over 31 per cent, Binance Coin declined 28 per cent, Cardano sank 35 per cent, XRP too dipped nearly 29 per cent while Solana witnessed the biggest fall of 40 per cent among the top 10 coins, showed CoinMarketCap, at the time of filing this report. Experts opined that recent policy announcements by the US Federal Reserve have had an impact on financial markets across the world and risk assets are being sold off as a result of the anticipated macro-economic downturn. Moreover, Russia and China also announced their actions to curb crypto in their domestic markets which led to a big sell-off in the Asian markets. This, in turn, is due to a move towards the reduction in liquidity as interest rates are poised to go up globally in Also read: Budget expectations: Need more regulatory focus around cryptocurrency, NFTs, says survey.

Understanding Ethereum’s Scalability Problems And The Solution On The Horizon
Blockchain promises to solve this problem. The technology behind bitcoin, blockchain is an open, distributed ledger that records transactions safely, permanently, and very efficiently. For instance, while the transfer of a share of stock can now take up to a week, with blockchain it could happen in seconds. Blockchain could slash the cost of transactions and eliminate intermediaries like lawyers and bankers, and that could transform the economy. In this article the authors describe the path that blockchain is likely to follow and explain how firms should think about investments in it.
Ethereum explores a fix for blockchain's performance problem
A representation of virtual currency Ethereum is seen in front of a stock graph in this illustration taken February 19, NEW YORK, May 7 Reuters - Ethereum has outperformed major digital currency rivals this year, bolstered by the surge in decentralized finance DeFi and the anticipation of a technical adjustment this summer, but it faces hurdles that could stall its rise. In the crypto world, the terms "ethereum" and "ether" have become synonymous. Technically, ethereum is the blockchain network in which decentralized applications are embedded, while ether is the token or currency that enables or drives the use of these applications. A rise in institutional interest has increased ethereum demand, but supply has been limited.
Analysis: Cryptocurrency ethereum is flourishing but risks linger
Ethereum, the second-biggest blockchain network in the world, has been suffering from scalability issues for the last few years. The non-scalability of the proof-of-work model shows that blockchains using this consensus mechanism cannot rise above single-digit transaction throughput numbers. Owing to this, the network is currently undergoing a transition to proof-of-stake, an alternative consensus mechanism that seems to, theoretically, solve the problems of the Ethereum network. The consensus mechanism of the blockchain would allow for many decentralized application to run on it, similar to a cloud deployment with the added security, decentralization and uptime of being on a blockchain. This caused a lot of new users and transactions on the blockchain, which has a transaction throughput of 15 transactions per second. The network became clogged and the cost required to use the network increased. The scalability issues are intrinsic to this consensus mechanism, owing to the fact that all transactions have to be broadcast to the network for every block, and the most secure node is one with all the data of the blockchain.

The transition to ethereum 2. But could this upgrade, a vital step towards a much greener and faster version of the current system, put ethereum on the path to becoming the dominant platform on the internet and make ether number one? Bitcoin is a system for allowing people to send value between one another without the need for banks. It is built on a technology known as blockchains, which are online ledgers whose transactions are checked and recorded by a decentralised network of computers known as validators. To make this more attractive, bitcoin is relatively scarce: only around 18 million coins are in existence and the protocol is such that there can never be more than 21 million. Ether works in a similar way to bitcoin, but ethereum is different.

In coming weeks, he plans to sell Decentral, and refocus on philanthropy and other ventures not related to crypto. Back in , Di Iorio co-founded Ethereum, which has become the home of many of the hottest crypto projects, particularly in decentralised finance - which lets people borrow, lend and trade with each other without intermediaries like banks.
