Blockchain, explained from the mechanics up
Short answer: three evergreen guides that cover what a blockchain is, how Layer 2 networks scale it, and how proof of work and proof of stake decide who writes the next block. Every load-bearing fact is checked against official protocol documentation, and each guide lists its sources.

How a blockchain works, mechanically: blocks and headers, SHA-256 hashing, Merkle trees, nodes, consensus, and finality, with an illustrative step-by-step block build.

OpenHow these guides are written
Protocol parameters (block intervals, challenge windows, validator deposits) are verified against official documentation such as developer.bitcoin.org and ethereum.org before they appear, and anything that cannot be verified is described without the number or left out. Worked examples are labelled illustrative. The guides are education, not investment advice; the editorial policy covers the standard for the whole site.
