The DTCC has signaled a major shift in how tokenized securities will operate on blockchain networks. Rather than consolidating everything on a single blockchain, they're advocating for a multi-blockchain approach with strong interoperability at its core. This move reflects growing recognition that different blockchain infrastructures serve different purposes—settlement speed, regulatory compliance, liquidity pools—and forcing everything onto one chain creates bottlenecks. By prioritizing cross-chain communication standards, the DTCC is essentially laying groundwork for a more fragmented but ultimately more resilient digital securities ecosystem. It's a pragmatic acknowledgment that the future likely won't be dominated by any single blockchain, but instead shaped by how well different networks can communicate and share settlement data.
