Ethereum is a public blockchain network that allows developers to build and deploy software programs directly on a shared, decentralized ledger — without relying on any company, server, or central authority to keep those programs running. Unlike Bitcoin, which was designed primarily to transfer value, Ethereum was built to run programmable agreements called smart contracts….
Bitcoin and Ethereum are the two largest blockchain networks by market capitalization, but they were built to solve different problems. Bitcoin, launched in 2009, functions primarily as a decentralized digital currency and store of value with a mathematically fixed supply of 21 million coins. Ethereum, launched in 2015, is a programmable blockchain platform that uses…
Ethereum gas fees are the costs users pay to execute operations on the Ethereum network. Every transaction (sending ETH, swapping tokens, minting a digital asset, or calling a smart contract) consumes a measurable amount of computational work, and that work is priced in gas. Understanding how Ethereum gas fees work means understanding a market for…
What is an ERC-20 token? – An ERC-20 token is a fungible digital asset built on the Ethereum blockchain that follows a shared technical standard defining how the token behaves, how balances are tracked, and how transfers execute. Every compliant token, whether a dollar-pegged stablecoin, a governance instrument, or a utility asset for a specific…
How smart contracts work on Ethereum: Smart contracts on Ethereum are programs stored on a public blockchain that execute automatically when predefined conditions are met, without any central authority enforcing or overseeing the agreement. Their terms are written in code, deployed to the Ethereum network, and carried out simultaneously by thousands of independent nodes. Once…
Ethereum layer 2 solutions explained: Ethereum layer 2 solutions are protocols built on top of the Ethereum base layer that process transactions off-chain, then settle the results back to mainnet — inheriting Ethereum’s security while eliminating most of its cost and congestion. Where Ethereum’s base layer handles roughly 15 transactions per second with gas fees…
Ethereum staking rewards guide: Ethereum staking rewards are the ETH paid to validators who lock up 32 ETH (or a pooled share of it) to help secure the network under its proof-of-stake consensus system. After the network switched from proof-of-work to proof-of-stake, validating blocks replaced mining as the mechanism for both processing transactions and issuing…
The two terms get used interchangeably in tutorials, wallet interfaces, and exchange help docs — but ethereum accounts vs wallets describe different things at different levels of the network. An Ethereum account is an entity on the blockchain itself: a unique address with a balance, a transaction history, and a state record maintained by the…
Ethereum network upgrades history is the story of a live, decentralized system reinventing itself from the inside out. Since the genesis block in July 2015, the network has completed more than 20 hard forks — each one bundling Ethereum Improvement Proposals (EIPs) that fix a specific limitation, introduce new capabilities, or prepare the ground for…
Ethereum is a programmable blockchain that lets developers deploy self-executing contracts: code that runs automatically when predefined conditions are met. Unlike Bitcoin, which functions primarily as a value transfer network, Ethereum was designed from the start as a general-purpose computing platform. That design decision opened the door to a broad range of applications, from financial…
