To interact with the ETC world computer requires communicating with a computer on the ETC network. It is relatively easy to set up a computer to become part of the network. This requires the installation of an implementation of the ETC communication protocols. Possible choices include Geth, Parity and Mantis. To use ETC, it is not necessary to set up a new computer on the network. Applications can simply request information from other network computers. Such applications are referred to as light clients. Whether using a light client or setting up a full network computer, users can communicate with the ETC network using Web 3.

Web 3

Web3 refers to a standard set of ETC application programming interfaces using the Javascript Object Notation Remote Procedue Call (JSON RPC) protocol. Web3 provides a convenient way to interact with ETC nodes and the ETC system. The name Web3 refers to the most ambitious goal for Ethereum Classic (ETC) which is to replace the World Wide Web (Web). Blockchain based replacements for the Web are often referred to as Web 3.0.

The Web was developed by Tim Berners-Lee and first made publicly available in 1991. It is a user friendly general purpose system based on the Internet. Initially the Web mainly contained simple static content such as primitive personal home pages. As the Web evolved, greater dynamism and interactivity was possible such as with social media. This improved Web is often referred to as Web 2.0. The term was popularized by Tim O’Reilly.

Neither the Internet nor the Web were initially designed to be trustless systems. Components have been steadily introduced to improve security such as Transport Layer Security (TLS), certificate authorities, and, Domain Name System Security Extensions (DNSSEC). Unfortunately, many such improvements are only partially adopted.

Gavin Wood popularized the term Web 3.0 for blockchain based trustless alternatives to the Web. Confusingly, Web 3.0 also sometimes refers to the Semantic Web.

Web 3.0 is a peer to peer replacement for the Web. A peer to peer architecture is required to build trustless systems. Web 3.0 users are pseudonymous. They are only identified by their accounts, unlike the Web, where addresses can be associated with identities. ETC requires access to additional short and long term storage systems to replace the Web. The InterPlanetary File System (IPFS) is an example of a compelling peer to peer storage system that can integrate with ETC.

The Web currently coexists with blockchain systems. Websites access these systems to provide additional functionality. As ETC and related systems mature, browsers will increasingly just point to these Web alternatives thus ushering in the era of Web 3.0.
