Blockchain transactions involve peer-to-peer transfers of digital assets, verified through consensus mechanisms such as proof-of-work (PoW) and proof-of-stake (PoS). Networks like Ethereum and Solana enable smart contract-based transactions, automating payments, lending, and governance. Users track transaction fees, gas optimization techniques, and network congestion to minimize costs. Innovations like layer-2 rollups, atomic swaps, and payment channels enhance transaction efficiency. The increasing adoption of crypto remittances, micropayments, and cross-border settlements solidifies blockchain’s role in financial technology.
