Lohkoketjulla

Lohkoketjulla is a Finnish term used to describe systems and approaches that employ blockchain technology. The word combines lohko (‘block’) and ketju (‘chain’) with the instrumental suffix -lla, yielding a phrase equivalent to “with blockchain.” In technical contexts lohkoketjulla refers to distributed ledger technologies that enable tamper-evident records across a network of participants.

A typical lohkoketjulla solution involves a distributed peer-to-peer network, cryptographic identities, a ledger of transactions, and a consensus mechanism to agree on the ledger state. Deployments can be permissioned or permissionless, and may incorporate smart contracts to automate rules. Privacy, data minimization, and GDPR compliance are common design considerations.

Applications include supply chain provenance, digital identity, land or asset registries, trade finance, and public-sector services in Finland and beyond. Proponents emphasize transparency, traceability, and resilience against single points of failure, while critics point to complexity, performance constraints, and regulatory uncertainty.

History and adoption in Finland have included government and industry pilots since the early 2010s, with experiments in document notarization, secure voting concepts, and interoperable identity schemes. Large-scale, nationwide deployment remains limited by standards, interoperability, and governance considerations.
