The latest version of AI Arena, [FLock.io](http://FLock.io)’s pioneering decentralised AI training platform, is officially here. Following V2.0 (May 2025), this V2.1 update revamps the reward distribution to be fairer and to promote long-term growth within the ecosystem.

See our [docs](https://docs.flock.io/flock-products/ai-arena) for our updated onboarding guide for AI Arena. Get ready to stake, train and earn on [train.flock.io](http://train.flock.io)!

What has changed in V2.1?
=========================

AI Arena V2.1 has introduced two major changes to the reward structure.

Change 1: Fairer rewards for training nodes and validators that receive a delegation
------------------------------------------------------------------------------------

Before the V2.1 upgrade there was a problem: training nodes and validators saw their personal rewards reduced when they accepted delegations because they had to share the same percentage pool.

V2.1 fixed this inherent unfairness to properly reward those training the model. We now use two separate reward percentage arrays: one with delegation and one without.

1.  **With delegation:** Total reward percentages involving delegators.
    
2.  **Without delegation:** Reward percentages solely for training nodes/validators.
    

The difference (1 - 2) represents the share between training nodes/validators and delegators, adjusted by the reward sharing ratio.

This means training nodes and validators no longer receive fewer rewards for having delegation. Consequently, it also means that delegators may have fewer rewards because now they are only eligible for the rewards attributed to the delegated amount.

Hovering over Claim FLOCK shows the Daily Rewards, Unlocked Vested Rewards and Pending rewards that are still under vesting

Change 2: Less ‘sell pressure’ on final day of task
---------------------------------------------------

Training nodes can also expect less ‘sell pressure’ on the final day of each task. We achieve this by only letting training nodes claim final rewards gradually.

Previously, 95% of rewards were unlocked in one go on the final day, and 5% were released on a daily basis. 

After this upgrade, 95% of rewards are instead unlocked gradually after the task has ended, with  the rewards being vested over 30 days. 

Vested rewards are adjusted every second, promoting stability and rewarding long-term commitment. There is no dilution regarding vested rewards. 

What do users need to do?
=========================

Nothing! With the update, changes are only made to the way rewards are distributed. How you stake, delegate and interact with pools remains intact.

What is AI Arena?
=================

AI Arena is a platform for competitive model training. Decentralised AI leader [FLock.io](http://FLock.io) launched AI Arena on [train.flock.io](http://train.flock.io) in May 2024. It brings Web3 a leap closer to traceable contribution and on-chain incentivisation for data owners, model developers and compute providers.

See you in the arena!
=====================

We can’t wait to see the V2.1 upgrade promote long term and sustainable growth and development within the FLock ecosystem. The team will be working closely with our community through Discord, Twitter, and developer channels. Head over to [train.flock.io](http://train.flock.io). 

A huge thank you to all the FLockies for being a part of this project!
