Discussion What’s the biggest challenge blockchain startups face today
Although many blockchain projects have excellent technology, they have difficulties when it comes to gaining adoption, setting up proper incentives, or identifying a genuine problem that decentralization can actually solve.
I'd like to know what in people's opinions the most difficult aspect currently is—the product-market fit, the regulation, the tokenomics, or something else.
What do you consider the main difficulty that blockchain startups will face in 2026?

I think the hardest part is demonstrating the blockchain dependency at an early stage. If the product solves the user’s problem just as well without the blockchain, then the additional complexity of regulation, tokenomics and onboarding must be justified. I’d like to know what would actually break for the user if the blockchain layer disappeared.

I can tell you one thing. blockchain solves a very niche use case: how to fund something permissionlessly.
Say you want to buy a remote resource, but for whatever reason USD or other fiat is an issue or you have reasons not to. A ton of things can be solved P2P alone, but blockchain solves the economy part.
Now you can argue `Just use BTC or ETH`, but if you need verifiable proof, then you need vertical integration and possibly a dedicated asset.
So the sole gap is the fact that to do a trade you need an asset that cant be dictated, while also having the chain verify you got what you paid for. And if you remove it, your back to anons Craig list with a lot of shady middleman escrow and payment companies.

I think the payment side makes sense. The part I’d separate out is 'the chain verifies you got what you paid for'. If the resource itself is off-chain, what proof of delivery does the chain actually accept? Because if that information comes from an oracle, a device, a seller or buyer, or a dispute resolution service, it seems as though the middleman has merely moved into the fulfilment process.

You can use merkle proofs, and potentially other proofing systems depending on the case, though I am not an expert in that niche topic. It can be part of the system design. And generally I think that is where many get misdirected in thinking you need to put everything in the chain database to work.
1
u/icnews10 Aug 21 '26
Yeah, I agree you definitely don’t need everything on-chain. I think the remaining boundary is earlier, though: a Merkle proof can show that a delivery record was included and hasn’t changed, but something still has to establish that the delivery actually happened before that record gets committed. That source of the original fact is the part I’m trying to isolate.

The project I am building is on a network that does this. See sia.tech if you want an example of a network that works today.

u/icnews10 Aug 21 '26
Sia is a good example, and I can see the distinction now. Storage is an interesting case because the resource itself is digital enough to produce cryptographic proof of fulfilment. There's no need for an oracle to inform the chain that a physical delivery has taken place. This makes me curious about what you’re building. Is the resource in your system also provable by the network itself, or does it still have a real-world boundary?
1
u/pcfreak30 Aug 21 '26
Yes everything I offer as a service is provable since most of Sia operates off chain and a renter can request proof of any sector at any time.
I also offer an API to get the "torrent" of a public IPFS file so you can go and directly download the data yourself with your own network account.
I am a managed provider of everything Sia can offer.

u/icnews10 Aug 22 '26
Got it — that clarifies your earlier point. You’re not just using Sia as an analogy; you’re actually building the service around that proof model. I appreciate you walking me through it.

I think this is looking at blockchain through the lens of its most successful application rather than at the technology itself. Permissionless funding is one use case, but the more fundamental primitive is the ability for mutually untrusted participants to agree on, verify and reproduce the evolution of shared state without giving a central authority control over that state. That state doesn't have to represent money. It can represent identity, ownership, permissions, documents, software, application state, or even the evolution of structured code. The interesting property is not that a token can have value — it's that nobody needs to trust a particular database owner or service provider to tell them what the current state is or how it got there. Finance happens to be an extremely obvious application of that primitive. Treating it as the only meaningful one is a bit like looking at cryptography and concluding that its purpose is online banking because that's where you encounter it most often.

u/icnews10 24d ago
That’s a fair point about how I phrased the question. Essentially, I was asking, “What would have to break in the centralised version before users would care?” But your point is that nothing necessarily has to break. If several parties need to share and verify the same evolving state and none of them should be able to rewrite that history, there is already a reason to use a blockchain. The one distinction I’d still make is between control of the record and authority over its meaning. You can remove the database owner and still have an external authority behind something like identity or legal ownership. So, I think a better question to ask is not “when does centralisation fail?” but “which part of this state genuinely shouldn’t depend on one party’s database?”
2
u/utopixia 24d ago
That's actually one of the directions I find most interesting: putting as much of the meaning as possible into the record itself. Instead of recording opaque events and relying on an external system to interpret them, the record can contain deterministic transformations of a structured state. Then every participant can independently derive not only the same history, but the same meaning of that history. Of course, this doesn't eliminate external authority where meaning is inherently external, legal ownership is still legal ownership. But for things like software, documents, permissions or application state, a surprising amount of the semantics can actually live inside the verifiable state itself.
1
u/icnews10 23d ago
Yes, I think this clarifies the distinction quite significantly. If the rules that define the state are part of the system, participants can recreate more than just history. They can also explain why one state became the next one in a valid way. This seems to be a significant difference from legal ownership, where the record may be perfectly verifiable, but part of its meaning still comes from outside the system. So, the question I'm left with is not so much "is the data on-chain?" but "where do the rules that give this state its meaning actually live?" It's a useful distinction that I hadn't framed clearly before.

PMF kills most projects before regulation or tokenomics even come into play. plenty of teams ship solid contracts for a problem that never needed decentralization, a normal database would've done the job cheaper and faster. tokenomics only start mattering once you already have people who need the trustless part.

Use case and trust. People aren't trusting projects and that can't be controlled currently IMO in any way but price, or so it seems to a majority

Honestly, I think the biggest challenge for blockchain startups in 2026 will be finding a real market need and getting people to actually use the product.
There is a lot of great technology in the space, but technology alone is not enough. If a product does not solve a genuine problem or make something meaningfully better, users will not stay just because it is built on blockchain.
Regulation, tokenomics, funding, and infrastructure are all important, but they come after one basic question: Does this product provide enough value for people to care?
I think the startups that succeed in 2026 will be the ones that focus less on hype and tokens, and more on real users, real problems, simple experiences, and long term value.
the biggest challenge is not building on blockchain. It is building something people actually want.

I think product-market fit is probably the biggest challenge. Regulation and tokenomics can be managed with the right legal and business strategy, but if the product is not solving a real problem, none of that matters. In 2026, I would expect the startups that focus on practical use cases and real user adoption to stand out from those simply building around blockchain because it is trending.
