Ethereum is the second-largest cryptocurrency by market capitalisation and the foundational infrastructure layer of decentralised finance. Unlike Bitcoin, which was designed primarily as a digital store of value, Ethereum was built as a programmable platform — a global computer that can run applications, enforce agreements, and process transactions without centralised intermediaries.
Nearly every major DeFi protocol, stablecoin, and onchain asset management platform — including UFarm.Digital — operates on Ethereum or a network built on top of it.
How Ethereum works
The Ethereum network is maintained by thousands of computers worldwide running the same software. Together they form a decentralised virtual machine that processes transactions and executes smart contracts. No single entity owns or controls it.
The network's native asset is Ether, referred to as ETH. It serves two roles: a store of value that can be sent and received like other cryptocurrencies, and the fuel that powers network activity. Every operation on Ethereum — deploying a smart contract, executing a transaction, interacting with a DeFi protocol — requires paying a fee in ETH. These fees are called gas, and they compensate the network participants who process and validate transactions.
Smart contracts on Ethereum
Smart contracts are the core innovation that makes Ethereum a platform rather than just a currency. They are programs stored on the blockchain that execute automatically when predefined conditions are met — without requiring either party to trust the other, and without any intermediary to enforce the outcome.
Ethereum was the first blockchain to make smart contracts practical at scale. Since launch in 2015, the platform has become home to thousands of applications: decentralised exchanges, lending markets, stablecoins, yield vaults, governance systems, and more. All of them run on the same underlying infrastructure, and all of their logic is publicly verifiable.
UFarm.Digital vault contracts are deployed on Ethereum. Every deposit, yield distribution, and withdrawal is governed by smart contract logic audited by independent security firms and verifiable by anyone on the network.
Proof of Stake
Ethereum originally used Proof of Work to validate transactions — the same energy-intensive consensus mechanism as Bitcoin. In September 2022, Ethereum transitioned to Proof of Stake, a fundamentally different approach.
Under Proof of Stake, validators contribute ETH to a staking pool rather than competing to solve computational puzzles. The network selects validators to confirm transaction blocks based on the size and duration of their stake. Validated blocks are confirmed by other validators through attestation, and all participating validators earn ETH rewards proportional to their contribution.
The transition reduced Ethereum's energy consumption by over 99% and improved the network's capacity for efficient, scalable transaction processing.
Ethereum and DeFi
Ethereum is the primary settlement layer for decentralised finance. The depth of its developer ecosystem, the maturity of its security tooling, and the volume of capital already deployed on the network make it the default choice for protocols managing significant user funds.
The DeFi ecosystem built on Ethereum includes lending markets, decentralised exchanges, stablecoin infrastructure, yield aggregators, and professionally managed vaults. Stablecoins like USDC and USDT — the base assets for most yield strategies — are primarily issued and traded on Ethereum.
UFarm.Digital operates on both Ethereum and Arbitrum, an Ethereum Layer 2 network that reduces transaction costs while inheriting Ethereum's security guarantees. This combination gives managers access to deep Ethereum liquidity and the cost efficiency needed for active strategy management.
ETH and gas
Understanding gas is practical for anyone interacting with Ethereum-based protocols. Gas fees are not fixed — they fluctuate based on network demand. During periods of high activity, fees rise. During quieter periods, they fall.
For DeFi users, gas costs factor into the economics of deposits, withdrawals, and rebalancing. This is one reason Layer 2 networks like Arbitrum have become increasingly important: they process transactions on a separate chain that settles to Ethereum, significantly reducing the cost of each interaction while maintaining the same security model.
The bottom line
Ethereum is the infrastructure layer that makes trustless, programmable finance possible. Smart contracts, stablecoins, lending markets, and onchain asset management all depend on it. For anyone participating in DeFi — as an investor, a manager, or a developer — understanding Ethereum is the foundation everything else builds on.
