Only by chatting with a supplier of BYD did I learn that BYD has a platform called Di Chain, where all suppliers in the BYD ecosystem must settle on Di Chain. Although it does not use blockchain technology, it essentially performs the functions of a major public chain, including issuing Tokens (electronic bonds of the BYD ecosystem), DEX (trading of electronic bonds), lending (collateral financing of electronic bonds), smart contracts (automatic circulation of electronic bonds in the upstream and downstream), etc. Currently, over 70 billion USD has been issued on Di Chain. If ranked among public chains, its TVL would rank as the third largest public chain, following Ethereum and Solana.
