Exploring Ether and the Ethereum Blockchain
Learn how Ether works within the Ethereum blockchain network, the potential applications of Ether, and how developers are working to scale the Ethereum blockchain.
Introduction to Ether
Ether is the native cryptocurrency of the Ethereum blockchain, providing a medium of exchange and acting as a fuel that incentivizes validators to maintain the Ethereum network.
Once a Proof-of-Work chain until late 2022, Ethereum is a Proof-of-Stake network, meaning that Ether holders can stake their coins to help secure the network and earn rewards. The staking process requires users to lock up 32 ETH to participate, but once they do, they are eligible for rewards from the network.
The rewards from the staking process are generated by the Ethereum network itself, using a smart contract system that automatically distributes Ethereum tokens to validators who are staking their coins. These rewards are paid out as Ether and can be used to cover transaction costs or held for future use, the value proposition of which supporters say will only become more attractive as the overall Ethereum network increases in adoption.
How Ether Functions Within the Ethereum Network
As the native token of the Ethereum blockchain, Ether plays a vital role in network function. At the heart of the Ethereum blockchain is the Ethereum Virtual Machine (EVM), which is responsible for executing smart contracts, managing consensus protocols, and validating transactions. All of these operations require Ether as a form of payment. Therefore, every action, every transaction, and every computation costs a certain amount of Ether.
The cost of each action is proportional to the computing power it takes to execute that particular action and is collected in the form of "gas." Gas is a fee or "tax" paid by users for using Ethereum's infrastructure — in general, the more computational power an action requires, the higher the gas fee.
Gas is denoted in gwei, which is a denomination of Ether (1 gwei = 0.000000001 ETH; similar to how 1 sat = 000000001 BTC). When users initiate a transaction, they pay a set gas price and gas limit to cover the cost of the transaction (which is subtracted from their Ether balance). Therefore, the higher the gas price, the faster the transaction will likely be processed.
Decentralized Applications (dApps)
Ether is used not only to fuel the Ethereum network but also to pay for the services provided by dApps. Many dApps seek a novel, trustless way of providing online services like finance, gaming, and digital identity management. To provide these services, dApps utilize Ether as payment for their services. By leveraging the power of the Ether as a cryptographically maintained value transfer system, dApps can provide services securely and transparently on the Ethereum blockchain.
For example, let's say you use the decentralized finance (DeFi) protocol Compound. As a dApp, Compound enables users to borrow and lend Ether and other cryptocurrencies. Before using the platform, you must deposit a certain amount of Ether into your account as collateral. Once you have done this, you can start borrowing or lending Ether. The amount of Ether you can borrow or lend is determined by the amount you have deposited as collateral. Compound charges you a fee in Ether to use its services as you borrow or lend Ether. This fee helps Compound continue to operate and provide users with a secure and transparent way to borrow and lend Ether and other cryptocurrencies.
In general, Ethereum supporters say that anywhere there is a need for trustless and secure digital transactions, Ether will have potential applications. However, these applications are untested and largely experimental:
- Decentralized Finance (DeFi) promises a financial revolution, enabling users to access traditional financial products such as lending, borrowing, and trading without relying on any centralized authority. Despite the potential of DeFi to revolutionize finance, there are substantial risks involved. With inconsistent code audits and proper oversight, users must manage their own funds and be wary of errors in protocols and smart contracts as well as malicious actors.
- Non-Fungible Tokens (NFTs): A type of digital asset uniquely identifiable and cannot be exchanged for any other asset.
- Decentralized Autonomous Organizations (DAOs): An organization run by a set of rules encoded into smart contracts on the Ethereum blockchain. DAOs are a relatively new, scam-prone, and experimental organizations, and their long-term viability is still uncertain.
- Tokenization of Assets: The process of converting rights to an asset into a digital token on the blockchain. Tokenization allows for the creation of a digital representation of an asset, which can be easily transferred and tracked on the blockchain. However, this process also carries some risks. For example, if the smart contract that underlies the tokenization process contains errors or vulnerabilities, it could result in the loss of the underlying asset.
- Supply Chain Management: A system of tracking and managing the movement of goods and resources from supplier to consumer.
- Distributed Cloud Computing: A type of cloud computing that runs on a decentralized network of computers.
- Digital Identity Management: A system of managing digital identities on the Ethereum blockchain, allowing users to store and manage personal data securely.
- Decentralized Prediction Markets: A market that allows users to bet on the outcome of events and receive rewards based on the accuracy of their predictions.
- Online Gaming Platforms: A platform that uses blockchain technology to facilitate creating and distributing digital assets in online games. Play-to-earn games like Axie Infinity allow users to earn tokens for participation.
Ethereum has already made strides in developing markets for NFTs, DeFi, DAOs, and more. However, as we've seen, there are still risks associated with smart contracts and decentralized applications that must be carefully considered. Security flaws, smart contract exploits, and systemic risk can all be factors that can lead to significant losses of funds. Therefore, before engaging in any Ethereum-based activity, it is essential to understand all the risks involved and take necessary precautions thoroughly.
The future of Ethereum seeks to revolutionize how we interact with digital assets and financial services, but to do that, the blockchain must scale efficiently. Ethereum's scalability challenge is one of the most pressing issues for developers and users. To deliver on Ethereum's promises, developers are working on solutions to improve scalability and efficiency. These include sharding, which divides the blockchain into smaller pieces for easier transaction processing, Optimistic Rollups that allow for scaling without compromising security, and zk-Rollups that enable privacy-preserving scaling.
Effective scaling solutions are critical for the success and continued growth of blockchain platforms like Ethereum. As demand for these platforms and their services increases, the ability to scale efficiently becomes increasingly important. Without effective scaling solutions, these platforms risk being unable to meet the needs of their users and potentially losing market share to competitors.
