Eleven years ago today, on July 30, 2015, the Ethereum blockchain officially went live with the launch of its first release, code-named "Frontier." The founding team mined the network's genesis block that day, marking the birth of what would become the largest smart-contract platform in the industry. Exchanges including MEXC marked the anniversary on X, with one post reading: "11 years, still building. Happy Birthday @ethereum."
The genesis block itself is a small piece of blockchain history in its own right. It contained 8,893 transactions allocating Ether to early addresses, and was mined at 15:26 UTC on launch day — the moment the network's transaction history began.
The Road to Launch
Ethereum's public debut followed a token sale conducted nearly a year earlier. The project's initial coin offering ran from July 22 to September 2, 2014, accepting Bitcoin in exchange for Ether at an initial rate of 1 BTC for 2,000 ETH. That sale raised roughly 31,000 BTC, worth about $18 million at the time, funding the development work that led to Frontier's launch the following summer.
The Ethereum Foundation, a Switzerland-based non-profit, coordinated much of the development and community organization in the lead-up to launch, a structure that has continued to shape how the network's core protocol development gets funded and directed to this day.
What the Launch Actually Changed
Ethereum's arrival introduced smart contracts to a mainstream blockchain audience for the first time — self-executing code that could run on a decentralized network without a central operator. That single capability became the foundation for decentralized finance, non-fungible tokens, decentralized autonomous organizations, and much of the broader Web3 ecosystem that exists today, all of which trace their technical lineage back to the virtual machine Ethereum introduced at launch.
Eleven years and multiple major upgrades later — including the shift from proof-of-work to proof-of-stake — the network's core premise from that first genesis block remains unchanged: a shared, programmable ledger that doesn't depend on any single company or institution to keep running.
