JPMorgan Chase, one of the largest banks in the world, conducted its first public transaction using blockchain technology. This transaction involves the transfer of tokenized government securities (treasury transfers), meaning that traditional financial assets have been converted into digital tokens that are managed on a blockchain network. For this purpose, the bank utilized the technologies of Chainlink, which provides reliable data and connection between the blockchain and external systems, and Ondo, a platform for asset tokenization. This is an important step towards integrating blockchain into financial operations, enhancing the transparency, security, and efficiency of transactions.
