# Blockchain zapisi

Blockchain je integralni dio DEXPIRY sustava i putem kriptografski autoriziranih transakcija omogućuje korisnicima stvaranje, slanje i primanje DEXPIRY tokena (ERC-721 NFT).

Distribuiranim zapisima može se pristupiti putem blockchain explorera ili putem DEXPIRY aplikacije, koja omogućuje prikaz raspodjele i prometa DEXPIRY tokena između korisničkih adresa u stvarnom vremenu.

Zapisi na blockchainu odobravaju se konsenzusom nodova i nije ih moguće naknadno mijenjati. Oni sadrže podatke vezane uz svaki [<mark style="color:green;">**DEXPIRY token**</mark>](/komponente-sustava/dexpiry-token.md) pohranjen na blockchainu, kao i kronološki zabilježene podatke o transakcijama svih DEXPIRY tokena u opticaju.
