What are the big problems in crypto today?

[reikagi]

I’m curious about a design where a blockchain isn’t optimized for speculation but for predictable settlement:
• deterministic block finality
• small validator committees with bonded stakes
• simple UTXO rules
• strong anti-spam admission policies
Basically a minimal, deterministic settlement chain.

What are the big problems in cryptocurrency today? What problems need to be solved? Please advise me.

From my perspective, altcoins have many problems, the biggest of which is that projects are created without any specific reason except scams, so the success of the project is not guaranteed, and scammers constantly set new traps by launching new altcoins. New investors invest in them after seeing the hype in the core, and at some point the project scam scares off new investors. Most altcoins in the market will disappear at some point. So it is wisest to invest in it with money that you don't mind losing.

What part of this haven't been solved by layer 1s that have launched over the years? I'm not saying there hasn't been one, I'm just saying there's a likely chance that one of such chains have been created. I think we should even move the conversation from how to optimize the blockchain to how we can utilize blockchain that build non-gambling apps that would gain traction and improve the overall standard of living for the average human.

Most systems try to solve everything at the base layer—smart contracts, DeFi, tokens, governance—but that tends to make the protocol heavier and harder to reason about. Bitcoin showed that a narrow base layer can be powerful precisely because it does less and stays predictable. The interesting question isn’t whether another chain exists, but whether we can build a base layer that remains simple enough to last decades while still being useful as a settlement foundation.

I’m not trying to launch another feature-heavy chain. The idea I’m exploring is whether a base layer that focuses only on deterministic settlement and simple validation rules might be easier for nodes and applications to reason about. Most modern systems add more functionality to the protocol itself, which increases complexity and attack surface. I’m curious whether keeping the base layer narrow and predictable could produce a more stable foundation for applications over the long term.
