The integration of Fidelity International into the Tokenized Collateral Network (TCN) of JPMorgan marks a significant step forward in the application of the financial industry on digital assets and blockchain technology. The TCN project of JPMorgan, which began with the tokenization of money market shares, aims to leverage blockchain technology to enhance transaction efficiency and security. By tokenizing money market fund (MMF) shares, investors can more quickly and efficiently meet margin requirements, thereby reducing transaction costs and operational risks.
