Etymology: The unit "dex" is a contraction of "decimal exponent." Astronomers and chemists use it to express a logarithmic change, where one dex means a tenfold difference. The shortening is simply the head of the phrase, reduced to three letters, so the term reads as a measure of powers of ten. A separate, unrelated "dex" comes from the names of drugs. Pharmacists and patients shortened long names such as dexamethasone and dextroamphetamine, both of which share the prefix "dex-" from the dextro- (right-handed) stereochemistry of their molecules. Clipping the first syllables gave a casual label that now stands in for several medicines. The blockchain sense is different again: it is an abbreviation of "decentralized exchange," a trading platform that runs without a central operator. The three-letter form is shared with the other senses, but its origin is the initials of that longer phrase rather than a clipping of a single word.
