The Athens Stock Exchange (ATHEX) is set to revolutionize the financial world by incorporating blockchain technology into its Electronic Book Building (EBB) system. In collaboration with the Sui blockchain ecosystem, ATHEX plans to create digital certificates for securities, offering enhanced security, efficiency, and transparency for its users. This integration simplifies the primary issuance process by merging securities allocation and settlement into a single confirmation, resulting in faster and more efficient transactions. The use of blockchain technology provides a significant security boost, as digital certificates on a public, immutable ledger reduce the risk of manipulation. It also enhances transparency, allowing regulators to monitor trade activities more effectively. The EBB, a new tool being developed by ATHEX, aims to be a future fundraising tool for companies to list transferable securities. The Greek stock exchange’s commitment to implementing blockchain technology places it at the forefront of innovation in the global market. While ATHEX leads the way in blockchain integration, other stock exchanges, such as the London Stock Exchange, are also exploring Web3 trends in the traditional finance space. This openness to new technologies could indicate a larger trend in the industry.
