Blockchain at the centre of your IT projects: Improve security, transparency and efficiency

Discover our IT expertise solutions based on blockchain

Explore the potential of Blockchain for business

Mainly known for its financial system based on crypto-currencies, blockchain is a technology that is often considered as complex but which offers many applications.

Trust, security, transparency and traceability of exchanges and transactions are valuable assets guaranteed by the use of blockchain and which offer new perspectives for companies and organisations

How is blockchain technology transforming many industries?

Blockchain offers many value-added features for many industries, including :

Native token management

A blockchain makes it very easy to create a system of token transfers between its participants. Cryptoassets have many facets, and many different uses. Beyond a possible stock value or use as a currency, we use cryptoassets on many types of projects: the field of asset securitization, loyalty points, voting rights, etc.

The NFT, a “non-fungible” token, exists in only one copy in a Blockchain. By linking the ownership of this single token to that of a physical asset (a car, a painting, a concert ticket), the Blockchain becomes a phenomenal tool for managing property titles, going far beyond the simple management of digital works of art.

A universal time stamp

What is recorded in a blockchain stays in a blockchain. It is one of the best digital evidence creation solutions on the market. Often simpler to use than an electronic signature approach using PKI and a trust organization, its evidentiary value is already accepted in many courts around the world such as in Italy, China or in many jurisdictions in the United States.

Forgery-proof data notarisation

Nothing is deleted in a blockchain. This functionality is perfect for storing immutable audit trails (ex. traceability of a food product), for document integrity control via the storage of the unique fingerprint of a digital document (e.g. transformation of an EDM into an electronic records management system) or for generating proof of prior art in the field of intellectual property.

Smart contracts to automate simple processes

Simple and efficient, a smart contract allows the automation of data and transaction processing in a decentralised way. The energy sector is investing in smart grids on blockchain, the traceability of containers in our international trade is facilitated by distributed registers, and our banking system is in the process of revolutionising its securities transaction settlement and delivery chains.

Blockchain technology is central to digital transformation projects

If our team of experts in blockchain technology can operate on any type of project, due to its historical skills, Coexya has however developed a specific Blockchain offer based on its IT expertise:

Blockchain and ECM

  • Use the Blockchain to generate electronic signatures
  • Give evidential storage value to your EDM
  • Certify outgoing documents (invoices, proof of address, etc.)

Blockchain and Intellectual Property

  • Generate prior art evidence for your copyrights and patents
  • Participate in marketplaces for your copyrights and patents
  • Automate your transfer/licensing/annuity payments

Blockchain and tracking

  • Food processing, maritime transport, pharmaceutical distribution… the sectors concerned are numerous.
  • Follow complex and often regulated business procedures
  • Facilitate interoperability between different players in the same market
  • Automate complex business transactions

 Coexya is involved in blockchain technology with a model largely focused on innovation

For nearly 20 years Coexya has been a specialist integrator of specialized technologies, and this successful model also extends to the Blockchain. We assist you whether your project starts from scratch or from a specification of several hundred pages.

Coexya stands out from many smaller companies by its ability to integrate many different technologies together. Our integrator business makes us an ideal partner for this type of project.

To discover the challenges of blockchain and cryptoactives, Coexya offers a range of training and consulting services, from one to one follow-up for members of management committees of large groups to training provided in seminars for few participants.



We work on all blockchains, including those known as “EVM”, Ethereum compatible. However, we differentiate ourselves from the market by two expertise.

On the public blockchain side, we are strongly involved in Tezos, which is one of the most recognized blockchains in the corporate world due to its multiple assets: low environmental impact, reliability, liquid proof-of-stake, on-chain governance and self-amendment, high level of decentralization, low gas costs…Coexya has chosen to be particularly involved in the Tezos ecosystem due to its corporate orientation and its level of reliability

Coexya’s commitment to Tezos is illustrated through several projects

  • DigiSign and Tediji : electronic signature solutions based on the Tezos blockchain
  • Choose your baker : a solution that facilitates compliance for blockchain users by allowing a transaction issuer to choose a baker or group of bakers to process its transactions on a public blockchain. Coexya is also a Corporate Baker and member of the Choose your Baker consortium.

On the private blockchain side, we have developed a skills centre on Hyperledger solutions, and in particular its Fabric component, which we are helping to deploy in the context of enterprise consortia projects. We are also very pleased to deploy the traceability software overlay provided by IBM: IBM Supply Chain Inelligence Suite: Blockchain Transparent Supply.

To discover blockchain technologies in the context of a business project, we suggest you read the book by one of our business managers, Alain Broustail, a specialist in blockchain
