Cosmos History: From Whitepaper to the "Internet of Blockchains"
2014–2016: From Tendermint to the Cosmos Whitepaper
Cosmos's story starts in 2014, when Jae Kwon founded Tendermint to develop a consensus algorithm that would let independent blockchains reach agreement faster and more efficiently than Bitcoin's classic Proof-of-Work. In 2016, Kwon and Ethan Buchman published the Cosmos whitepaper, describing a vision for an "Internet of Blockchains" — a network of independent, interconnected chains.
2017: One of the Fastest ICOs in History
In April 2017, the Cosmos team held an ICO and raised $17 million in under 30 minutes — the fundraise had to be cut short due to overwhelming demand. It became one of the most notable ICOs of its time.
2019: Mainnet Launch and an Ecosystem Is Born
The main Cosmos Hub network went live in March 2019. From that point on, a whole ecosystem of independent projects grew around the Cosmos SDK — a toolkit for building custom blockchains — including Binance Chain, Osmosis, and Terra (before its 2022 collapse).
In 2020, Jae Kwon stepped down as CEO of the Interchain Foundation amid internal disagreements, remaining the technology's principal architect, while leadership passed to Peng Zhong.
2021–2022: The IBC Protocol and a Price Peak
A key technical milestone was the IBC (Inter-Blockchain Communication) protocol, which let different Cosmos SDK-based blockchains exchange tokens and data directly. Amid the broader bull market, ATOM reached an all-time high of roughly $44.70 in January 2022.
