Cuy Sheffield, head of Visa's blockchain, said in a blog post on Wednesday that despite various flaws and issues, blockchain technology is similar to the early days of the Internet and is developing from obscurity to ubiquity. Sheffield believes that blockchain technology - in terms of efficiency, related costs, and usability - may mature in the next decade.

In addition, he expects Visa's payment network to involve not only "multiple currencies and bank settlement tracks, but also multiple blockchain networks, stablecoins, and CBDC or tokenized deposits." (Decrypt)
