The first block of the Ardor mainnet was forged shortly after midnight on January 1st, 2018, marking the launch of the first public multi-chain blockchain ecosystem.

Together with the parent chain, three child chains were also activated at launch - Ignis, AEUR, and Bitswift. For the first time in history, multiple transactions submitted to a child chain could be bundled into a single transaction on the parent chain, the security of each child chain being ensured by the proof-of-stake consensus on the parent chain.

The Ardor public blockchain has been running stable ever since, and is under active development according to our roadmap below.
