Blockchains present a "serverless infrastructure" and have evolved from securing a limited state in first-generation blockchains like Bitcoin, to securing both state and business logic in newer generations like Ethereum and Polymesh. These blockchains act as a global trusted computer for code storage and execution, with some computational bounds but a low barrier to entry for developers. The unified execution layer provides composability guarantees, which is a unique situation for technology. Protocols like ICP further enhance this by incorporating containerization.
