When artists sell their work, they must provide a Certificate of Authenticityin order to be more professional and give all the guarantees to the buyer. A Certificate of Authenticity is essential for the attribution of a work.

Without a Certificate of Authenticity, it's impossible to determine the artwork's origin or to attribute it to an artist. The only value it has will depend on its size, the technique, the materials, and the subject represented.

A Certificate of Authenticity is the key to the successful sale of your works. You must provide a Certificate of Authenticity to the buyer (even if he or she does not ask for one) along with the invoice.

Without a Certificate of Authenticity, most doors will remain closed; no estimate, no transaction. A Certificate of Authenticity is mandatory to establish that a work of art is authentic and has been created by the Artist.

No mention in a raisonné catalog about the financial value of the artwork. Without a Certificate of Authenticity, it's impossible to evaluate the artwork, its only value depends on its size, its technique, the materials used and the subject represented.

What is a Certificate of Authenticity?

A Certificate of Authenticity is a document that is used to attribute a painting, sculpture or photograph to an artist. Important: an invoice cannot serve as a Certificate of Authenticity.

What is the value of a Certificate of Authenticity?

The value of a Certificate of Authenticity depends on the authority of the person writing it, if he or she is recognized by all professionals as the most competent for this subject or artist at the time the certificate is written.

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.
