Blockchain

When working with blockchain, a distributed ledger that records transactions across many computers, ensuring transparency and tamper‑resistance. Also known as distributed ledger technology, it powers everything from digital money to supply‑chain tracking.

Key Concepts Around Blockchain

One major offshoot is decentralized finance, or DeFi, which recreates banking services on open protocols without intermediaries (DeFi). Another cornerstone is smart contracts, self‑executing code that runs when predefined conditions are met, enabling trustless agreements. Cryptocurrency, digital assets that use cryptographic techniques for secure transfers, is the most visible blockchain application (crypto). Finally, nodes, individual computers that validate and store the ledger, form the backbone of any blockchain network (network participants).

These entities form a logical chain: blockchain encompasses DeFi, DeFi requires smart contracts, and smart contracts rely on cryptocurrency as the native medium of value. Instant finality, a feature where transactions become irreversible within seconds, enhances blockchain settlement speed and reduces counterparty risk. In practice, a network that offers instant finality often uses Proof‑of‑Stake or Byzantine Fault Tolerance mechanisms, balancing speed against decentralisation. Understanding the attributes—like consensus type, tokenomics, and node requirements—helps you evaluate any blockchain project’s strengths and trade‑offs.

Below you’ll find a curated set of articles that break down these concepts further. From deep dives on DeFi exchange reviews to step‑by‑step guides on running full nodes, the collection covers practical tools, security considerations, and emerging trends. Dive in to sharpen your knowledge, spot opportunities, and avoid common pitfalls as you navigate the ever‑evolving blockchain landscape.
