Internet Computer – Replacing all of traditional IT with a blockchain | Dominic Williams | Fundamentals ep.68

Article hero image

The Internet Computer is a general-purpose blockchain that hosts canister smart contracts. It is designed to provide a World Computer that can replace traditional IT and host a new generation of Web3 services and applications that run solely from the blockchain, without the need for traditional IT. It can also play the role of Web3 orchestrator, by interacting with traditional blockchains.

In this episode with Dominic, we talk about the big vision behind the Internet Computer, and what the journey has looked like from initial idea to launching mainnet. Dominic walks us through the main technical innovations that have needed to be introduced to enable the vision for a true world computer, and we speak about the compelling real-world use cases that the IC can facilitate, and how adoption has been progressing for some of them.

Listen to the episode:

We cover the evolution of smart contracts, identity authentication, open internet services, and building tamperproof, autonomous, and sovereign infrastructure.

Tune in for a great discussion about restoring the Internet to its open, innovative, and creative roots.
