IRC (Internet Relay Chat) Created
Jarkko Oikarinen creates IRC, the decentralized chat protocol that would later host Bitcoin's first trading markets and developer discussions.
In August 1988, Finnish developer Jarkko Oikarinen wrote the code for Internet Relay Chat (IRC) while working at the University of Oulu. Intended to replace the local 'Talk' program on bulletin board systems (BBS), IRC established the first scalable, real-time, text-based communication network that operated through a federation of distributed servers. Unlike modern messaging apps like WhatsApp or Slack which rely on centralized corporate servers, IRC was designed as an open protocol where anyone could run a server and connect it to the global network. This decentralized topology allowed the network to survive even if individual nodes were severed, a resilience model that influenced the design of subsequent peer-to-peer systems.
IRC introduced key concepts of digital identity and community organization—specifically 'channels' (chat rooms) and 'nicks' (nicknames)—that became the cultural bedrock of the early internet. Users could form communities instantaneously around specific topics without seeking permission from a platform administrator. This permissionless structure made IRC the natural home for the hacker, cryptography, and open-source communities throughout the 1990s and 2000s. It was on IRC (specifically the freenode network) that the early Bitcoin developers coordinated, where Satoshi Nakamoto discussed technical details, and where the first over-the-counter (OTC) Bitcoin trades were negotiated in channels like #bitcoin-otc.
The protocol's longevity—it remains in active use over 30 years later—demonstrates the robustness of simple, open standards over proprietary walled gardens. For Bitcoin, IRC provided the initial 'social layer' that allowed a distributed team of volunteers to coordinate the build-out of the financial layer. IRC fostered the formation of the borderless technical communities that would eventually birth and nurture Bitcoin, providing the communication infrastructure that made permissionless development possible.
