Blockchain based architecture can be efficiently used to keep product traceability. Token and transaction metadata can help to create a traceability system directly on the blockchain.


A blockchain wallet is a digital wallet composed of public and private keys that allows one to manage cryptocurrency. Wallets have a receiving address and a unique identifier such as a staking address.


Blockchain tokens are chunks of information stored on the blockchain to attest to file ownership that can represent a physical or digital item. Token metadata (text information structure in a JSON like format) store product property and details. Product information will be always accessible immutable and the manufacturer can claim the ownership digitally.

Transaction Metadata

Essential information about a batch creation or product transfer are contains in metadata. This information indicates previous transaction, receiver, product and batch, amount transferred. Metadata content allow to trace transaction backward and can be verified automatically using a blockchain explorer.

Social Network

Blockchain can contain public information store in a decentralized manner directly in the token metadata transaction. Every publication can be identified by a unique transaction hash. User will login using their wallet, information can be used cross platform and created out of one specific platform. User can be free of which information he will access.

  • Open Access
  • Decentralized
  • Immutable


Certification is necessary for everyone to prove his degree. Blockchain token can represent a certification or diploma, then a transaction can designate graduated student by their wallet in the metadata.
