Space travel can now be paid for with cryptocurrency. Payment solution provider Shift4 Payments has partnered with Blue Origin, allowing users to pay for space trips using Ethereum. The logic behind this collaboration is straightforward—Blue Origin, owned by Bezos, is expanding its payment options, and Ethereum, as the world's largest smart contract platform, naturally becomes the first choice. This is not only an attempt to apply blockchain technology in high-end consumer scenarios but also a sign that cryptocurrencies are deeply penetrating the traditional business world. From DeFi to space travel, the boundaries of Web3 are continuously expanding.
