Artcertificate's Blockchain

Certificat Blockchain

Artcertificate allows artists and professionals to create and register certificates of authenticity which will then be included in the Blockchain on the Ethereum network. A specific option allows the transfer of any certificate to the Blockchain with one click.

What is: Artcertificate Blockchain?

It's a fully managed Blockchain registration service that facilitates the creation and management of a scalable network of blockchain and distributed registry technologies used for COA Certificates of Authenticity. All COA's can be registered on the blockchain with one click and get a certificate of authenticity on Artcertificate's Blockchain (COABC).

Decentralized management:
A blockchain allows Artcertificate to create COA certificate of authenticity records where different members of the network can check the authenticity of the records without the need for a reliable central authority (Control is done outside of Artcertificate). Each party, known as a member, has a peer node in the network.

Artcertificate Blockchain uses a reputable block chain framework.

Ethereum is perfect for highly distributed block chain networks, where the transparency of data from all members is important and allows all participants in the network to independently verify the activity of every member. Ethereum also allows us to join a public Ethereum block chain network.

The register is decentralized and managed by an Ethereum blockchain that is shared among the members. The control of the registrations is independent from Artcertificate. The registration of the COA is made following the specific request of the applicant.
