Blockchain is supposed to be the foundation of a decentralized internet.
But there’s one major limitation hardly anyone talks about—data storage.
Everyone’s talking about how blockchain will power the future of AI, Real-World Assets (RWA), and fully on-chain applications. But before we get there, we need to answer one very basic question.
Let’s separate myth from reality.
The Common Misconception
This statement gets thrown around a lot—but the reality is more nuanced.
Technically, you can store large files. But you probably shouldn’t. Not with how current blockchains work.
Let’s explore why 👇
The Technical Wall
Most blockchains today—Ethereum, Solana, Avalanche, even Bitcoin—weren’t built for storing data. They were built to record state changes (like transactions), not house full-sized files.
Here are the three biggest issues:
1. Storage Is Insanely Expensive
On Ethereum, storing 1GB of data can cost over $100,000 in gas fees.
Yes, you read that right.
That’s because blockchain storage is priced in gas, and each byte of data comes with an execution cost. The result? Storing even a simple image or document on-chain becomes cost-prohibitive for most use cases.
2. Most “On-Chain” Apps Aren’t Really On-Chain
Take NFTs, for example.
Most NFT metadata (and actual media) isn’t stored on the blockchain—it’s stored on IPFS or other off-chain storage solutions. The smart contract just points to where the file lives.
What this means:
If the off-chain file disappears, your NFT is broken.
If the storage host fails, your “ownership” vanishes.
You didn’t really own it in the first place.
This applies to AI models, real-world documents, and game assets too. Most apps claiming to be "on-chain" are really just wrappers for centralized storage.
3. Retrieval and Speed Are a Mess
Even when data is stored on-chain, retrieving it is often slow and fragmented. Blockchains aren't optimized for data queries. They’re optimized for immutability and consensus.
If you need to fetch structured datasets in real-time—for AI, finance, analytics, or even RWA pricing models—you’ll likely end up back on centralized servers to avoid delays.
So... What’s the Point of “On-Chain” If the Data Isn’t There?
This is the elephant in the room.
We say we want full decentralization. Yet most of today’s "Web3" stack still relies on:
Off-chain storage
Centralized APIs
Fragile infrastructure
The Fix? It Starts with Storage.
New solutions are emerging—approaches that rethink how data lives on-chain from the ground up.
Not just indexing files. Not just pointing to IPFS.
But actual, scalable, affordable, native on-chain storage.
The next evolution of blockchain won’t just verify transactions.
It will store real data, enable real ownership, and support real on-chain AI and applications.
A breakthrough is coming.
And when it does—everything changes.
The fix has a name.
And it’s coming from Vanar.
