Nxt

NXT is an open source cryptocurrency and payment network launched in 2013 by anonymous software developer BCNext. It uses proof-of-stake to reach consensus for transactions—as such, there is a static money supply. Unlike Bitcoin, there is no mining. NXT was specifically conceived as a flexible platform around build applications and financial services, and serves as basis for ARDR, a blockchain-as-a-service multichain platform developed by Jelurida, and the cryptocurrency IoTeX. Jelurida stewards of Nxt, which became a child chain of Ardor. In 2026, generations of new blocks and transactions on the Nxt blockchain halted, at block 6 million. On February 1, 2026, the Nxt child chain was activated on the Ardor chain. Nxt software and source code is still available under a public license.
