It included EIP Metropolis Difficulty Bomb Delay and Block Reward This allows for reductions in gas costs and increases in transaction throughput. Gas fees for smart contracts can be costly, so this update kept contract creators from losing gwei—the small ether denomination used to pay for. Regarded as the third phase of Ethereum's evolution, the Metropolis-Byzantium soft fork functioned more like an operating system upgrade.

This rollout included three critical updates to Ethereum: the removal of centralization on the network, enabling users to hold and transact with ETH, and to write and deploy smart contracts. Widely regarded as the only Ethereum fork of any significance, this hard fork was based on the controversial DAO event.
The original chain became known as Ethereum Classic, and the new chain moved forward as the main Ethereum chain. This September hard fork event required all software users to upgrade their clients in order to stay with the current network. Enhancements included better security, stability, and network performance for higher volumes of traffic.
Constantinople is the current version of the Ethereum blockchain. This hard fork occurred concurrently with the St. Petersburg update. The Ethereum community is preparing for the next hard fork event Istanbul, scheduled for release on December 4th, Community members have speculated what changes will come with Serenity, but many agree that the Ethereum blockchain will shift focus from Proof of Work to Proof of Stake.
Proof of Stake means that there is less competition for completing blocks of data, significantly reducing the energy required to process data. Currently, a single Bitcoin transaction consumes the same electricity as 1. Ethereum continues to be a leading blockchain platform, with the highest number of decentralized apps dApps and a massive, engaged community. To date, cryptocurrencies have largely been the focus of news headlines.
Feeling bored on social media? Consider investing in profile picture NFTs, one of the most popular digital assets being traded today. How do you represent yourself on social media? Profile picture NFTs are pieces of digital artwork that people use to express themselves online. To learn more, this infographic explains how three well-known profile picture NFT collections were created.
CryptoPunks are commonly regarded as one of the first examples of NFTs. One interesting fact is that these NFTs were originally given out for free—today, they are worth thousands or millions of dollars each. The following table shows the species distribution of the CryptoPunks collection. Examples include a big beard found in only punks , and a VR headset found in punks. This opens up many combinations of clothing items, facial features, and accessories.
To explore further, visit the BAYC gallery. As its name suggests, the BAKC is a collection of dogs, rather than apes. Cool Cats were minted at a cost of 0. Each Cool Cat NFT is a depiction of a cartoon cat with a varying number of facial features, hats, and shirts. Altogether, there are over , possible options that could be included. Think back, for a moment, to the days of MySpace.
Users could spend hours customizing their profile page, adding music, art, and whatever else they felt was an expression of themselves. The metaverse offers something similar. To take part in a virtual universe, you need an avatar—a digital manifestation of yourself. Avatars will be highly customizable and far less constrained by the limitations of the real world. This may help to explain the recent craze around profile picture NFTs. Bitcoin mining requires significant amounts of energy, but what does this consumption look like when compared to countries and companies?
Cryptocurrencies have been some of the most talked-about assets in recent months, with bitcoin and ether prices reaching record highs. These gains were driven by a flurry of announcements, including increased adoption by businesses and institutions. Lesser known, however, is just how much electricity is required to power the Bitcoin network. This requires them to solve numerical puzzles which have a digit hexadecimal solution known as a hash. Miners may be rewarded with bitcoins, but only if they arrive at the solution before others.
It is for this reason that Bitcoin mining facilities—warehouses filled with computers—have been popping up around the world. These facilities enable miners to scale up their hashrate , also known as the number of hashes produced each second. A higher hashrate requires greater amounts of electricity, and in some cases can even overload local infrastructure. On March 18, , the annual power consumption of the Bitcoin network was estimated to be terawatt-hours TWh.
Note : A terawatt hour TWh is a measure of electricity that represents 1 trillion watts sustained for one hour. When compared to larger countries like the U. Other types of clean energy such as wind and solar appear to be less popular. Coal energy plays a significant role in the Asia-Pacific region, and was the only source to match hydroelectricity in terms of usage. But far from just a boon for the nascent technology, there is real risk in the rollout.
It is immature experimental tech," ethereum protocol developer Vlad Zamfir emphasized in a tweet earlier this year. If there's one upgrade that will lay this fact bare, Metropolis may be it. Because substantial changes to the platform put real money in danger, ethereum developers have been inclined to take their time, choosing to write off grumblings from users, entrepreneurs and a market that seems eager for the technology to make its next big advance.
Hudson Jameson, the unofficial release manager for Metropolis, emphasised that the devs "always err on the side of caution" — a hesitancy which, although well advised, has lead to a string of delays. But timeline aside, there's actually been big changes to the plans.
Metropolis, once conceived as the stage at which a user-friendly version of the technology would finally go live, has seen shifts that could change the final code rollout dramatically. Accordingly, the upgrade has now been split into two steps, named Byzantium and Constantinople, and though both are still evolving, an early picture of how they might ultimately impact the network is now taking shape.
As it stands today, Byzantium is set to involve a total of nine ethereum improvement protocols EIPs , or individual code patches to the network. These include changes such as fixing the problem of difficulty adjustments, 'returndata' operations, 'static call' operations, new precompiles, a difficulty delay feature and embedding transaction return data in receipts.
All of these are engineered to make the network function more efficiently while minimizing potential exploits. Changes are underway that will better handle faulty code within smart contracts, so that payments will fail if there are mistakes in the programming. Additionally, these changes will have a transformative impact for the lifecycle of a contract, as contract upgrades can be pre-configured into the original code. Contracts will also be newly secure, as certain changes are engineered to protect against something called a re-entrancy attack when untrusted code enters a contract to manipulate it.
A new feature for embedding transaction return data in receipts will make it possible for light clients to determine if a transaction was successful or not without actually executing the transaction in a virtual machine. This will also affect off-chain tools. Another upgrade will delay the difficulty bomb which currently detonating across the network, ensuring that transaction times do not become intolerable.
Transaction times are currently at around 25 seconds — high by ethereum's second standards. This update will also decrease the rewards that miners are given for blocks, which will mean that the mining process will be faster and cheaper. Another mining fix eliminates a previous error in the difficulty adjustment, to insure that the block time remains more stable.
New precompiles released on Byzantium pave the way for something called zk-snarks — a cryptographic procedure that for the first time, will allow genuinely private transactions to occur on the ethereum network. This is produced in collaboration with z-cash, the privacy-centric cryptocurrency that is the first widespread application of the technology. Unfortunately, there is no release date set for Constantipole, the second hardfork of Metropolis.
This is because certain edits were found to threaten assumptions set deep in ethereum's code, opening the doors to a number of potential exploits. One EIP that is planned, though, paves way for lighter client implementations, by simplifying the process of evaluating a transaction. Currently, the evaluation of contracts requires both the current state of the blockchain and the hashes of the last blocks. For lighter clients to exist this heavy information processing needs to be substantially reduced — and EIP 96 does this in an elegant way.
Yet, the main roadblock appears to be with EIP 86, the planned centerpiece of the project, and the most interesting and complicated of all EIPs. EIP 86 wants to bring about the abstraction of account security, making accounts more flexible and more customizable, while allowing new features to be elaborated.
