One of the biggest downsides of sharding is how it can compromise security if it's done poorly. Now, you may be thinking "This is genius! Why wasn't this done from the start?!" - the answer, to be blunt, is that life isn't that simple. More lanes and parallel processing leads to much higher throughput." Instead of transactions being executed in a consecutive order, they'll be handled simultaneously - and this is clearly a much cleverer use of computing power.Īs the ConsenSys team explained: "Each shard chain is like adding another lane to upgrade Ethereum from a single lane road to a multiple lane highway. It effectively involves splitting the blockchain mainnet into loads of tiny shard chains that run alongside each other. Sharding is the technology that will make Ethereum 2.0 scalable. This means that, as well as contributing to the quest for financial freedom, the blockchain won't be calamitous for the environment. Imagine that Ethereum 1.0 is a busy road with a single lane going in each direction, meaning all of the cars have to crawl through at a slow pace when there's congestion.Įstimates from the Institute of Electrical and Electronics Engineers (that's IEEE for short) suggest that the ETH 2.0 upgrade will cut energy usage by a whopping 99%. How Is Ethereum 2.0 Different From Ethereum 1.0?īlockchain technology company ConsenSys has a neat way of describing how ETH 2.0 is different to its predecessor ETH 1.0. To sum up, the Ethereum network consists of both the execution layer and consensus layer. The foundation also expects the upgrade to ramp up security and dramatically reduce the levels of computing power and energy currently used - making the project more sustainable and "better for the environment." Overall, it's hoped these improvements will futureproof the Ethereum blockchain - ensuring it can handle thousands of transactions per second, all while making transactions faster and cheaper to use. We hope this updated terminology will bring clarity to eliminate this scam vector and help make the ecosystem safer." "Unfortunately, malicious actors have attempted to use the Eth2 misnomer to scam users by telling them to swap their ETH for 'ETH2' tokens or that they must somehow migrate their ETH before the Eth2 upgrade. The blog post went on to explain that Ethereum 2.0 has actually become "an inaccurate representation of Ethereum's roadmap," adding: By removing Eth2 terminology, we save all future users from navigating this confusing mental model." Or that Eth1 ceases to exist once Eth2 exists. "They intuitively think that Eth1 comes first and Eth2 comes after. "As work began on the Beacon Chain, it became clear that the phased Ethereum 2.0 roadmap would take several years to deliver fully."ĭevelopers argue that the use of the phrase Ethereum 2.0 "creates a broken mental model for new users," explaining: It's clear that the Ethereum Foundation's decision has been motivated by a number of external factors. Hence, Vitalik proposed that Ethereum 1.0 effectively "merge" with Ethereum 2.0 and act as " shard 0". However, it was soon discovered that various elements in the Ethereum 2.0 chain would take too long to deliver, while others like the Beacon Chain are more realistic to achieve. This is because in the original roadmap, Ethereum 2.0 represents the new PoS chain that miners would migrate too, while the Ethereum 1.0 PoW chain would be made obsolete by a difficulty bomb. The purpose behind this rebrand is so developers could accurately describe their progress along with Ethereum's roadmap.
