Practical applications of blockchain .

In the public sector :

1. NGOs and non-profits face a loss of confidence year after year. Negative headlines suggest that these organizations manage funds poorly, which can discourage donations. However, Blockchain-based supply chain implementation would make transactions traceable, offering full visibility on the use of funds.
2. As far as taxes are concerned, it offers promising potential for simplifying tax calculation and payment in the future. By automatically recording information such as salaries and expenses, the system would be transparent, comprehensible and even enable automated payments. This would considerably reduce administrative errors and the associated costs.
3. A Blockchain-based voting system for elections would be an ideal solution for truly secure and unforgeable elections. Votes could be tracked anonymously, guaranteeing an accurate and tamper-proof vote count, thus reinforcing the integrity of the electoral process.
4. In the area of compliance and legislative controls, the "RegChain" project in Ireland has paved the way for better compliance, greater transparency and more secure storage of sensitive data, thanks to Blockchain technology. The issuing of diplomas and certificates has also been made more reliable and accessible. Universities and public administrations could issue immutable diplomas and certificates, easy to verify with personal keys, offering a global solution without the need for costly notarial processes.

6. To strengthen cybersecurity, it offers a reliable solution by securely encrypting data and providing an integrated infrastructure to combat Internet fraud and piracy. This approach helps to enhance user security and prevent various problems associated with cybercrime.

Health system :

In healthcare, Blockchain technology offers considerable benefits for patients, healthcare providers and researchers. It enables patients' medical histories to be tracked, facilitating care coordination and medical research. This could lead to more accurate diagnoses and more effective treatments.

1. Hospitals can take advantage of the Blockchain by storing medical records securely, guaranteeing the confidentiality and security of patient data. Patients, meanwhile, can access their medical records securely via a unique digital identifier, while controlling who can view this information. This approach promotes better patient care and better communication between healthcare professionals, improving the quality of care provided.
2. In the insurance sector, Blockchain-based smart contracts present interesting applications for insurance companies. The technology enables contracts and claims to be settled seamlessly, eliminating disputes and duplicate claims. This greatly simplifies payment and policy management processes, delivering a better customer experience and greater operational efficiency. In addition, traceability and immutability reinforce trust between insurance stakeholders.

• Artists, media and advertising: It can be used to pay artists and content creators directly every time their work is used or consulted. This fights piracy and ensures fair remuneration for artists.

Financial institutions

• In the field of international payments , by enabling faster, more secure and cost-effective transactions, without traditional intermediaries such as banks. Thanks to the use of Blockchain, transactions are encrypted and verified, guaranteeing the security and speed of money transfers on a global scale. This approach significantly reduces transaction costs while improving the efficiency of financial services.

• Peer-to-peer (P2P) transactions s have also been greatly facilitated, enabling direct money transfers between individuals and businesses without worrying about geographical limitations or the costs associated with traditional financial services. Users' confidence in these services is strengthened by faster, more secure transfers.

• Capital markets are also attracting the attention of major financial institutions, which see Blockchain technology as an opportunity to process transactions more efficiently. Although the development of this technology requires time and complexity, some start-ups have already made significant progress in this field, benefiting from the support of renowned investors.

• Trade financing by simplifying and accelerating the letter of credit process, thereby significantly reducing transaction times. What used to take weeks can now be accomplished in a matter of hours thanks to this technology.

• In the prevention of money laundering , due to its transparent, non-manipulable nature. Smart contracts and transparently recorded transactions make it easy to identify and verify the parties involved in transactions, reinforcing compliance and anti-money laundering measures.

• It also offers advantages in shareholder voting. It enables shareholders to exercise their voting rights relatively easily and transparently. An electoral token is generated according to the shares held, and voting rights can be exchanged more easily thanks to this technology.
