A blockchain is fundamentally a distributed ledger. Transactions are grouped into blocks, and each block is cryptographically linked to the one before it, which makes historical records extremely difficult to alter after the fact. Instead of a single administrator holding write access, the ledger is replicated across many independent nodes, and every transfer must be agreed upon by the network's consensus rules before it becomes final.

Responsive design requires a single set of pages to display correctly across screen sizes. Elastic layouts, media queries, and relative units are the usual tools, and avoiding fixed pixel widths prevents the horizontal scrolling that plagues poorly adapted mobile pages.

Double spending is one of the central problems in digital currency design. Without a central clearing authority, the network must find a way to ensure that the same funds cannot be spent twice, which is achieved through consensus rules, timestamps, and the public broadcast of every valid transaction to all participating nodes.

A cryptographic hash function maps an input of arbitrary length to an output of fixed length, and it is effectively one-way. Changing a single character in the input produces an entirely different output, an effect known as the avalanche property. This behaviour underpins file integrity checks, password storage, and the chaining of blocks inside a blockchain.

The first step in web performance work is identifying the bottleneck. Browser developer tools expose the timing, size, and blocking behaviour of every request, which makes it possible to target compression, caching, or deferred loading of non-critical scripts instead of guessing.
