Sei's concept of a 'global settlement layer' is pretty interesting—essentially aiming to be an on-chain version of SWIFT + Nasdaq. Sub-second confirmations, institutional-grade custody, real-time price feeds—these infrastructures are indeed being gradually improved. The involvement of big players like BlackRock, Circle, and Chainlink shows that on-chain settlement is being taken seriously. The traditional T+1/T+2 settlement cycles in finance do feel outdated in the digital age. 24/7 real-time settlement is the trend. The key question is whether it can truly handle institutional-level capital flows and compliance requirements.
