Ardor (ARDR): how it works, supply and reviews

In short

Type: Multichain platform: one parent chain (ARDR) plus child chains with their own native tokens.
Initial distribution: The Ardor genesis was built from a snapshot of the Nxt blockchain at height 1,636,363.
Risks and caveats: Funds sent to a new account are protected only by a 64-bit account ID until its public key is recorded; someone could brute-force a passphrase that maps to the same ID.

What is Ardor

Ardor is a proof-of-stake blockchain platform developed by the software company Jelurida. It uses a parent and child chain design: the ARDR parent chain secures the network, and child chains such as Ignis have their own tokens and carry most transactions. Ardor evolved from the Nxt software, and its mainnet genesis is set to 1 January 2018.

Network and consensus

Network and consensus — Ardor
Parameter	Details
Type	Multichain platform: one parent chain (ARDR) plus child chains with their own native tokens.
Consensus	100% proof of stake; blocks are forged, not mined.
Block time	About 1 minute on average.
Launched	Mainnet genesis timestamp 00:00 UTC, 1 January 2018 (first production release 2.0.9).
Forging	Accounts with more than 1,000 ARDR held for 1,440 blocks (about 24 hours) can forge.
Child chains	The current wallet covers the Ignis, BitSwift and Triffic child chains.
Software	Production software 2.6.3, released 24 June 2026.
Runs on	The public Jelurida mainnet node reports application Ardor 2.6.3, state up to date.

Supply and issuance

Supply and issuance — Ardor
Parameter	Details
Initial distribution	The Ardor genesis was built from a snapshot of the Nxt blockchain at height 1,636,363.
Total supply	Total amount reported by the node: 998,466,231.2566 ARDR (8 decimals), 1 November 2026.
Forging rewards	Forgers receive the transaction fees of the blocks they forge; child-block fees are split across the last 4 forgers, 25% each.

What ARDR is used for

ARDR is the only token used in Ardor's proof-of-stake consensus, so it secures all child chains.
Fees on each chain are paid in that chain's own coin; end users do not need ARDR, and a business can sponsor fees by running a bundler.
Holding more than 1,000 ARDR for about 24 hours lets an account forge blocks and earn fees.

Who develops and governs Ardor

Developer: Jelurida, a Swiss blockchain software company that develops and maintains Nxt and Ardor.

History

History — Ardor
Date	Event
2013	Nxt, the platform Ardor evolved from, launched in 2013 as a fully proof-of-stake cryptocurrency.
2016	Jelurida was incorporated in the Netherlands to develop and maintain the Nxt and Ardor platforms.
2017	Jelurida moved its main operations to Switzerland.
1 January 2018	Ardor mainnet genesis: the first production release set the genesis timestamp to 00:00 UTC on 1 January 2018, from a snapshot of Nxt at height 1,636,363.
24 June 2026	Ardor 2.6.3 was released as the current production version.

Security and audits

An account that has only received funds is protected by its 64-bit account ID; Ardor recommends one outgoing transaction to record the 256-bit public key on the blockchain.
The default Ardor passphrase is 12 random English words from a dictionary of more than 1,600 words.

Security incidents

No security incident is recorded in the sources checked on 1 November 2026 (the company’s own channels and incident databases): defillama.com/hacks, hacked.slowmist.io/search, rekt.news/leaderboard, jelurida.com/news/ardor, ardordocs.jelurida.com/Ardor_Software_Change_Log

Risks and caveats

Funds sent to a new account are protected only by a 64-bit account ID until its public key is recorded; someone could brute-force a passphrase that maps to the same ID.
Ardor's parent chain is secured only by ARDR held for forging, under a fully proof-of-stake design.
The Android full node is closed-source software, unlike the open-source desktop release.
