Összefoglalás. A blokklánc-technológiákat első sikeres alkalmazásuk, a
kriptopénzek tették híressé és hírhedté. Valódi jelentőségük azonban az általuk
létrehozott új informatikai rendszerkategóriában, az adatbázis jellegű, több
résztvevő által közösen hitelesen tartott elosztott főkönyvekben rejlik. A tanulmány
ismerteti ezek alapelveit, jellemző üzleti alkalmazási mintáit és a
„blokkláncosítást”, mint bevezetési stratégia tervezési elvet. Új eredményként a
blokkláncosítás a biztonság területén alkalmazhatóságának megteremtéséhez
felállításra kerül egy ismert példákon alapuló érték-modell.
Summary. Blockchain technologies were made famous – and arguably,
infamous – by their first successful application: cryptocurrencies. Their true
significance, however, lies in the novel IT system category they established:
distributed ledgers, which are electronic systems of records maintained by multiple
parties. The paper summarizes the key concepts of distributed ledger technologies,
their key business application types and „blockchainification” as an innovation
strategy planning methodology. As a novel contribution, the paper proposes the
application of „blockchainification” in the complex context of security, and sets up
an initial version of the necessary domain-specific value and application type
framework.
Distributed Ledger Technologies (DLT) have reached maturity where they can be applied
to, and have been demonstrated to be able to, facilitate a very broad range of
cross-organizational and client-organization cooperation patterns. For enterprise and
industrial usage, DLT key value dimensions, supporting blockchain capbilities and
value driver application types have been already collected, facilitating the
structured and benefit-based planning of their introduction.
One such approach is what we coined „blockchainification”. Blockchainification
starts with a decomposition of the business architecture of an organization, to the
point where specific cooperations can be characterized, both functionally and by the
parties involved. Given such a decomposition, the viability of migrating or replacing
the functionality with a DLT-based solution can be assessed, on a cooperation by
cooperation basis, including the associated risks and benefits. This way, a
blockchain introduction strategy can be formulated for the gradual introduction of
DLTs. Additionally, blockchainification suggests – at least in the first phases of an
introduction strategy – an emphasis on solutions where a DLT essentially just
„replaces” the current information system support of already-digitized
cooperations.
While in the enterprise and industrial sphere blockchainification is already
facilitated by an example-based understanding of key value dimensions, blockchain
capabilities and value driver applications, for many other domains, these
prerequisites are missing. Importantly, what is already available is not readily
applicable for organizations involved in security activities in the broad sense; in
many aspects, the value these organizations seek from IT systems is markedly
different from the enterprise world. Thus, the paper proposes an initial key value
dimension and supporting blockchain capability model for organizations involved in
providing a select set of security services.
