lohkoketjuun

Lohkoketjuun is the Finnish illative form of lohkoketju, meaning "into the blockchain" or "to the blockchain." In Finnish grammar the illative case expresses movement into or direction toward something; lohkoketjuun therefore conveys the idea that data, assets or actions are being placed on or committed to a blockchain.

The base word lohkoketju is a compound of lohko ("block") and ketju ("chain"), a calque of the English term blockchain that entered technical and public discourse with the rise of distributed ledger technologies. Lohkoketjuun is commonly used in contexts such as software documentation, news reporting and everyday speech to describe transactions, recordings or processes that are executed on or appended to a blockchain (for example, "tiedot tallennetaan lohkoketjuun" — "the data is stored on the blockchain").

Usage of lohkoketjuun can appear in both literal technical descriptions and broader figurative or policy discussions about immutability, transparency and decentralization. As with other case forms in Finnish, its specific meaning depends on context and accompanying verbs; it differs from locative forms (e.g., lohkoketjussa, "in the blockchain") that emphasize location rather than movement or transfer.
