As a pioneer of the multi-chain structure concept in blockchain, the Ardor public chain is entering a new evolutionary cycle. With the successful completion of the on-chain voting hard fork of the established public chain NXT , and its imminent integration into the Ardor ecosystem as a sub-chain, Ardor officially unveils a new chapter of "on-chain multi-dimensional collaboration".
Meanwhile, Ardor version 2.5.3 was also officially released recently, providing technical support for the deployment and migration testing of Nxt subchains on the testnet, marking a substantial breakthrough for Ardor in terms of inter-chain interoperability, historical compatibility, and ecosystem integration.
This process is not only a technological evolution, but also an ecological awakening.
I. NXT Hard Fork Successful: Community Consensus Drives On-Chain Governance
In November 2025, the proposal by Jeluida to migrate NXT to the Ardor subchain underwent a decisive vote. By introducing an on-chain forger voting mechanism, the community successfully implemented a fork competition based on block versions, and the migration proposal was approved.
According to the consensus process, the NXT mainnet will officially stop producing blocks around January 20, 2026. Subsequently, it will be snapshotted and imported into the Ardor mainnet to continue operating as a brand new "Nxt sub-chain".
This process is both a practice of decentralized governance mechanisms and a bold exploration of "technological continuity" and "ecological compatibility".
II. Ardor v2.5.3 Released: Safeguarding NXT Migration Testing
Following the successful hard fork, Jeluida released the latest Ardor v2.5.3 . This version is a mandatory upgrade for the testnet, and its core purpose is:
Activate the Nxt subchain based on the NXT mainnet snapshot;
Verify the compatibility of the snapshot import mechanism with inter-chain functions;
Improve network layer stability and asset system interaction performance.
Through this step, Ardor not only verified the technical feasibility of the migration process, but also made comprehensive preparations for the final integration of the mainnet in 2026.
III. Why Ardor? The Real-World Implementation of Multi-Chain Architecture
Since its launch in 2018, Ardor has stood out in the blockchain world with its " main chain + sub-chain " structure. Compared to the traditional single-chain model, Ardor sub-chains have the following advantages:
Independent assets and functional configuration;
Native interoperability with other subchains;
Shared main chain security and consensus mechanism;
Lower deployment and management barriers.
The integration of NXT is not only a "real-world validation" of Ardor's multi-chain architecture, but also a technological fusion of classic and modern approaches.
NXT, with a 12-year history, is the world's first PoS public blockchain, boasting mature functional design and fair token distribution. Now, it joins Ardor as a subchain, retaining its own characteristics while being empowered by the main chain, truly achieving "continuation rather than abandonment" and "upgrade rather than reconstruction".
IV. Ecological Reconstruction and a Diverse Future: Ardor's Awakening Moment
With the upcoming launch of the Nxt subchain, the Ardor ecosystem is moving towards a more complex, inclusive, and sustainable collaboration model. This is not merely an increase in the number of subchains, but signifies more than just this:
Enhanced Ecosystem Diversity : Nxt, as the first "historical chain" to migrate a sub-chain, breaks down the barriers between chains;
User tier expansion : Existing NXT holders will be seamlessly transitioned to the Ardor ecosystem, activating the existing community;
Unleashing development potential : The JPL license, plug-in system, and snapshot tools will provide an integrated implementation path for new projects;
Upgraded governance model : On-chain voting governance practices provide a template for future sub-chain activation and parameter adjustment.
This migration is not only a tribute to the past, but also an embrace of the future.
V. In conclusion: Ardor, in its evolution, is awakening.
The development of blockchain goes beyond the technology itself; it is more about the adaptive capabilities of the ecosystem and the "self-evolution" capabilities of projects. Ardor public chain's successful implementation of the NXT migration, v2.5.3 release, and on-chain governance mechanism demonstrates a viable path of "multi-chain integration, consensus-driven development, and ecosystem symbiosis."
In the future, with the mainnet launch of the Nxt subchain and the deployment of more DApps and subchain projects, the Ardor ecosystem will not only be a blockchain platform, but also a "multi-chain collaborative operating system".
The evolution of the Ardor public chain doesn't stop there; a true awakening is underway.
