As we know Bitcoin is the OG of cryptocurrencies. The first time I heard about bitcoin, in my mind I conjured an image of a giant digital coin which had wild price swings and could give banks the middle finger all day long. While these were all fantasies, they also had an element of truth. After all, as of today, I haven’t used a bank account in a very long time. I use exchanges, non custodial wallets and mobile money wallets and the last time I was in a real bank for personal business was 3 years ago. So, I would say that I am one of the people who have been most affected by the blockchain revolution.
While Bitcoin laid the foundation for blockchain technology, the crypto universe has since evolved and exploded in complexity as well as ambition. As of today, there is a fierce race that is unfolding for digital supremacy and blockchain platform that would power the next digital currency revolution. This is artificial intelligence (AI). Now, let's dig in and see where this race may take us.
I would like to let us look at the era of Layer-1 blockchains and the exciting sprint towards dominance over AI innovations.
What is a Layer-1 blockchain?
If you take the blockchain as a cake, then Bitcoin is the first layer that is dense, heavy and foundational. This heavy bitcoin layer was mainly built for one thing, that is to be digital money.
So, when we talk about Layer-1 blockchains, we mean base layer networks on which everything is built. Ethereum popularised this idea after bitcoin, introducing a concept of smart contracts. And, these smart contracts are codes that exist on the blockchain and they act as minicomputers that automatically execute tasks.
After this popularisation by Ethereum, we have seen the creation and development of many Layer-1 blockchains with unique features.
- Solana offers speed and lightning fast transactions.
- Avalanche has serious scaling muscle, so if you want to scale, then avalanche is for you.
- Polkadot allows inter-blockchain networking and interoperability.
- Cardano on the other hand is academic and has a research backed approach.
All these Layer-1 blockchain networks are competing to be the go to platform for decentralised applications(dApps), decentralised finance (DeFi), gaming and AI.
Why all the noise about AI?
When many people think about AI they visualise robots and scifi stuff, but that is not what we are talking about. AI is everywhere, from your phone’s voice assistant to self-driving cars. The current wave of AI innovation is demanding computing power, speed, secure data sharing and trust mechanisms. This is where we need blockchain technology.
The blockchain’s decentralisation means that no single entity controls the data. This is very crucial when dealing with sensitive personal or proprietary AI algorithms. Many Layer-1 blockchains are trying to evolve to support this by offering fast, secure and scalable infrastructure.
There is a race for AI ready Layer-1s
A few years back, Layer-1 blockchains were competing over speed and transaction costs, but this is not the case anymore. Everyone is running around scrambling to become the backbone for AI models and services. This is because whoever cracks this will unlock a trillion dollar value in blockchain plus AI synergy. Any Layer-1 that is going to break this code must be able to provide a lot of value.
The first characteristic a Layer-1 should have for synergy with AI is data integrity and provenance. AI models heavily rely on data quality and the blockchain provides an immutable ledger in which data cannot be altered sneakily once recorded. This is very important if we are to train trustworthy AI models. Several Layer-1 blockchains are integrating tools to verify data sources and track data lineage. Now, imagine if we can have an AI doctor app that can prove the medical data it used to train your diagnosis was legit and tamper proof. This is the game changer that will be coming if the Layer-1s are successful.
Some Layer-1 are exploring decentralised AI market places. Imagine Alibaba, but for AI services running on a Layer-1 blockchain. Developers want a place to sell and share their AI models securely. Consumers also want to use these models without risking their data or bias. Networks like Ethereum 2.0 and emerging chains are attempting to host these decentralised app marketplaces , where trust is automated by code.
Others are trying to explore the sharing of computational power. One limitation of the blockchain has been slow processing speeds. However, new Layer-1s are integrating technologies that allow users to sell their idle computational power to AI developers who need heavy duty computing. Now, if you have a few GPUs lying around, you would share the power with someone who needs it to train AI models in a decentralized, cheap and efficient way.
The winners of this race will shape the future and take money
Any Layer-1 blockchain technology that successfully integrates with AI applications is more likely to dominate the web 3 wave. They will be able to create a vision of the internet in which data, identity and money will flow seamlessly powered by decentralised technology. In addition this blockchain will offer another price in the form of technological sovereignty.
As governments and corporations are racing to control AI, decentralised blockchains will offer developers an escape hatch from government control and monopoly. In this case AI innovations become more democratised not monopolised. This is an opportunity for Layer-1 networks to not just construct networks but to build the future internet’s foundation.
Ethereum is leveraging AI for network optimisation while Polkadot is exploring interoperability between blockchain and AI systems. Even some newer Layer-1s are launching with AI-native architecture from day one. They are showing up to a pistol fight with submachine guns while their older competitors are still loading innovation bullets.
Direct integration; the AI twist nobody saw coming
Several Layer-1 blockchain networks are now integrating AI directly into their architecture. This is because AI needs computing power, data verification and decentralised infrastructure which is exactly what the blockchain technology has in store. There is going to be a trade because the blockchain technologies need smarter systems for optimisation, security and efficacy which AI provides.
Projects like Fetch.ai and Render Network are leading this charge by creating infrastructure where AI agents can operate autonomously on decentralised networks. Such AI systems can execute complex tasks without centralised gatekeepers. Many other projects are working to develop AI integration in areas such as:
- On-chain AI inference where machine learning models are run directly on blockchains.
- Decentralised AI learning where they would distribute AI model learning across networks.
- AI-optimised validators in which machine learning is used to improve blockchain security and consensus.
What about bitcoin, is it still relevant?
You may be wondering about the relevance of bitcoin in an age where Layer-1 innovations are more prominent. And yes, I believe Bitcoin is still very relevant. It remains digital gold and its value proposition is unmatched with pure store of value terms. However, Bitcoin’s scripting language may not be suitable for powering AI as its scripting language is just too simple for this kind of complexity.
Layer-1 blockchains like Ethereum, Solana and others are stepping into Bitcoin’s shadow, combining smart contracts, AI capabilities and scalability. While this creates a rich cryptoexperience, they cannot replace the role played by bitcoin.
For investors and developers, this is both an exciting and confusing area. The diversity of Layer-1 blockchains means that there are different use cases and such cases will find different homes. Ai integration is not only hype, it's a genuine technological evolution that could unlock previously impossible applications.
Final thoughts and conclusion
While Bitcoin opened the door, Layer-1 blockchain networks are building the mansion. In this case AI becomes the smart system that makes everything in the blockchain useful. While there is a race for AI integration in the blockchain, there will be winners and losers. However, the winner will take all and at the end the real winners are the consumers and users of these innovations. But I am so excited about this, after all we are witnessing the foundation of something great, an innovation built around complete intelligent systems that don't require permission slips from Mark Zuckerberg.
This means that the future of web 3 is not just decentralised, its also artificially intelligent.
