3 AI Blockchain Projects for Your Watchlist
Dear Subscriber,

| By Jurica Dujmovic |
Last week, I introduced you to the latest evolution in blockchain technology: a cutting-edge new consensus mechanism called Proof of Intelligence, or PoI.
To recap: Instead of the complex algorithms used to validate transactions on that blockchain, PoI mechanisms validate blocks by working on actual AI problems to train machine learning models, optimizing algorithms or processing AI datasets.
Your hardware still validates transactions and secures the network. But now it's multitasking by contributing to advancements that might actually matter.
I mentioned last week that, while the technical challenges remain substantial, PoI’s potential benefits — channeling blockchain's computational demands toward meaningful AI advancement — are too compelling to ignore.
To show the potential of this new tech, I’ve reviewed three interesting PoI projects, each with its own take on how to implement this new consensus mechanism.
While still in the early stages, their approaches showcase the varied possibilities of this technology.
PoI Blockchain 1: Lightchain AI
This innovative project is one of the most intriguing players in the PoI space.
Like other PoI projects, its approach requires validators to contribute to deep learning optimizations and natural language processing tasks instead of traditional mining puzzles.
But what really caught my attention is Lightchain AI’s (LCAI, Not Yet Rated) integration of zero-knowledge proofs (ZKPs) and homomorphic encryption to verify AI computations without exposing proprietary data.
This integration solves the fundamental privacy paradox in decentralized AI computation. It allows validators to prove they correctly executed complex AI tasks … without exposing sensitive data.
This could be a significant breakthrough for the development of secure collaborative AI across organizations which traditionally need to guard their proprietary information, like in the medical or cybersecurity fields.
Utilizing AI in this way could potentially accelerate innovation while maintaining the trustless verification blockchain networks require.
However, before you get all hyped up, I should note that Lightchain AI is still very much in development. Its token is only in presales and not available on any DEXes at the time of writing.
According to their roadmap, prototype development only began in November 2024, with subsequent implementation phases planned throughout 2025.
These concepts are incredibly compelling, but we'll need to wait to see how effectively they deliver on these technical promises.
It's definitely one to watch, though the usual "early-stage project" cautions apply.
PoI Blockchain 2: SingularityNet
SingularityNET (AGIX, Not Yet Rated) is a decentralized AI marketplace built on blockchain technology. It enables AI developers to create, share and monetize AI services at scale.
It is taking a more practical "show me the money" approach to AI consensus. According to documentation, the platform uses a hybrid model combining Proof of Stake (PoS) with a sophisticated Proof of Reputation (PoR) mechanism to secure its decentralized AI marketplace.
Its PoR mechanism essentially tells users to put their money where their mouth is, as its AI is good enough to stake tokens on it. Each rating carries financial weight, either through direct payment for completed tasks or by freezing tokens as collateral.
SingularityNET's roadmap also reveals plans for a Reputation Inspection Agent. Its purpose would be to use AI techniques to analyze transaction patterns to identify suspicious activity that could undermine the reputation system.
While not a pure PoI implementation, this hybrid approach demonstrates a sophisticated combination of financial incentives, multi-dimensional reputation tracking and anti-fraud mechanisms in an AI-blockchain convergence platform.
PoI Blockchain 3: NeuroChain
NeuroChain.io (NCC, Not Yet Rated) — not to be confused with Neurochain.ai — is another player I've been watching in this space.
According to its whitepaper, this team has developed a platform that integrates artificial intelligence across various sectors including finance, logistics and cybersecurity.
What really grabbed my attention about NeuroChain is its AI-driven governance approach. This system relies on Intelligent Bots (AI agents) to work alongside a decision protocol to assess the quality of AI computations.
This represents one of the more sophisticated implementations of AI-blockchain integration I've encountered.
The platform operates through several distinct components. At its core is what they call Proof of Involvement & Integrity (PII) combined with a Proof of Workflow mechanism, which together function similarly to the Proof of Intelligence.
Instead of relying on traditional smart contracts, they employ "intelligent applications" that autonomously decide how to process data. Each Bot carries an integrity score that's continuously updated based on its performance. If a Bot produces invalid or malicious outputs, the consensus automatically lowers its integrity score and can exclude its contributions, ensuring only high-quality computations are validated and rewarded.
The practical applications span multiple industries.
In finance, NeuroChain enables fraud detection and risk assessment.
For logistics, the platform enhances supply chain optimization, tracking and transparency.
And in cybersecurity, its AI-driven monitoring provides proactive defense by detecting anomalies.
By integrating AI deeply into its infrastructure, NeuroChain joins the ranks of promising PoI implementations that could reshape how we think about blockchain utility.
But as exciting as all three of these projects are, I'd be doing you a disservice if I painted only the rosy picture.
Remember, PoI is still brand new. And PoI blockchains are just scratching the surface of what’s possible.
That means there will be growing pains alongside the new milestones. And it’s why I listed some of the biggest concerns around this new tech last week.
If you can handle more risk and are looking to get in on the latest crypto tech breakthrough, there are a few key notes to keep in mind before you move forward.
Considerations for Interested Investors
If you're thinking about dipping your toes into the PoI waters, here are four factors you’ll want to consider before you take the plunge:
- Team composition. You should always evaluate the strength of the team behind any project you plan to invest in. But for PoI projects in particular, you’ll want to see leadership with expertise in both blockchain technology and artificial intelligence. This dual expertise will be critical in overcoming the technical challenges ahead.
- Practical applications. Pay attention to how the project addresses real use cases. Remember, utility drives adoption, not technical novelty. So any project that implements PoI solely as a novel consensus mechanism is unlikely to go the distance.
- Developer ecosystem. A healthy community of developers and researchers can make or break a project's long-term development. To see how developers feel about a project beyond what the marketing materials say, you can review GitHub activity.
-
Technical progress. This is where you’ll need to do a little more heavy lifting. Don't just take a project’s word for what progress has been made — dig into the actual development milestones for yourself!
Once you’ve read a project’s white paper, you’ll want to move on to look at its functioning repositories, testnet deployments and verifiable results. Those will separate the “pie-in-the-sky” dreamers from the real movers and shakers.
Any project can paint a beautiful theoretical picture; what you want to see is code that actually runs and solves real problems in the wild.
As I said last week, this convergence of AI and blockchain technology is one of the most intriguing developments to watch in both fields.
I’ll be watching these projects closely. And I’ll let you know if any other promising projects catch my attention.
In the meantime, I encourage you to do your own research on Lightchain, SingularityNET and NeuroChain to see if you should add them to your watchlist, as well.
Best,
Jurica Dujmovic
