Historically, proved is the older form, while proven arose as a Scottish variant - see etymology. Used in legal writing from mid 17th century, it entered literary usage more slowly, only becoming significant in the 19th century, with the poet Alfred, Lord Tennyson among the earliest frequent users (presumably for reasons of meter). In the 19th century, proven was widely discouraged, and remained significantly less common through the mid 20th century (proved being used approximately four times as often), by the late 20th century it came to be used about equally.
As an attributive adjective, proven is much more commonly used, and proved is widely considered an error - “a proven method", not *“a proved method".
From Scottish English, as past participle of preve, a Middle English variant of prove - compare woven (from weave) and cloven (from cleave), both of which feature -eve â†’ -oven. preve died out in England, but survived in Scotland, where proven developed, initially in a legal context, as in “The jury ruled that the charges were not proven." See usage notes for historical usage patterns.
Earlier, from Late Latin probÅ (“test, try, examine, approve, show to be good or fit, prove", verb), from probus (“good, worthy, excellent"), from Proto-Indo-European *pro-bhwo- (“being in front, prominent"), from Proto-Indo-European *pro-, *per- (“toward") + Proto-Indo-European *bhu- (“to be").
