Altcoins That Fix Bitcoin's Problems, and What They Cost

Bitcoin has real limitations. It settles a few transactions per second, it cannot run meaningful programs, and every payment you have ever made with it is permanently visible to anyone who knows your address.

Those are not slanders. They are design consequences, and Bitcoin's own developers would state them roughly the same way.

So an entire industry exists to fix them, and most of that industry markets itself to you as an upgrade. I want to walk through the fixes that are genuine, because several are, and then be specific about the part nobody puts in the pitch: every one of these fixes costs something, and in at least one case the thing it costs is the clarity of the Shariah ruling.

That last category is the reason this article is on this site rather than a general crypto blog.

The throughput fix, and what it takes

Bitcoin does roughly seven transactions per second. Litecoin confirms blocks four times faster and Bitcoin Cash raised the block size so more fits in each one. Both are Halal on our screen, scoring 88 and 80. Both are older than most of what gets called innovation, both have worked continuously for a decade, and neither introduces any mechanism the fiqh has to think about. They are Bitcoin with a parameter changed.

What did they trade? Security budget and network effect, mostly. A chain with fewer miners is a chain that is cheaper to attack, and bigger blocks make running a full node more expensive, which pushes verification toward people with better hardware. That is a decentralisation cost paid in exchange for a throughput gain. Whether it was worth it is an argument, not a fact.

The newer answer is to not touch Bitcoin at all and build above it. Stacks is a Bitcoin Layer 2 that adds programmability while settling to Bitcoin, Halal at 81. That approach costs you complexity and a new trust assumption at the layer above, which is a real cost, just a different one.

The programmability fix, and the question it introduces

Bitcoin deliberately cannot run arbitrary programs. Ethereum was built because of that, and at 96 it scores level with Bitcoin on fundamentals. Solana at 85, Avalanche at 85, NEAR at 89, Polkadot at 89 and Hedera at 89 all pass, all Halal, all doing genuine work.

Here is the cost, and it is the one this site exists to talk about.

Almost every one of these secures itself with proof of stake rather than proof of work. Which means the network pays holders a yield for locking tokens up. Bitcoin has no such mechanism, so it never raises the question. These chains raise it on day one.

Our position is that native staking rewards for validating a network are payment for a service, not interest on a loan, and most of these pass on that basis. But look at Cosmos. It scores 85, its infrastructure is entirely permissible, and its verdict is Doubtful. Not because of anything the chain does wrong, but because its staking yield is funded substantially by inflation emissions rather than by real network fees, and being paid in newly printed tokens for holding tokens is a mechanism scholars genuinely disagree about.

That is the sentence I want you to take from this article. Cosmos is not doubtful because it is a worse project than Bitcoin. It is doubtful because solving a problem Bitcoin does not have required a mechanism Bitcoin does not need.

If you want the longer treatment of where that line sits, we wrote it separately. The short version is that the funding source matters, and "it pays yield" is the beginning of the question rather than the end of it.

The privacy fix, and the one nobody expects

Bitcoin's ledger is public. Anyone paid in Bitcoin by an employer can be tracked by that employer forever.

Monero fixes this properly, and here is the result that surprises people: it is Halal, and it scores 93, which is higher than Solana, higher than XRP, higher than most of the chains in the previous section. Privacy is not a Shariah problem. Concealment of a transaction is not deception, and protecting your financial affairs from strangers has a long and unembarrassed history in Islamic practice.

Zcash offers optional privacy and is also Halal, scoring 68, lower mostly because optional privacy that few people use is weaker privacy.

The cost here is not fiqh. It is law. Privacy coins are delisted from major exchanges in several jurisdictions and outright restricted in others, which means your exit is narrower and your legal position depends on where you live. That is a genuine risk, it is just a different kind of risk than the one people assume, and we treated it fully in the privacy coins article.

Where the pitch is usually dishonest

Three things to watch, because this is where "solves Bitcoin's problems" turns into marketing.

Most projects claiming to fix Bitcoin are not competing with Bitcoin at all. They are competing with Ethereum, for developers, and using Bitcoin's name because it is the one you recognise. Check what the chain is actually used for before accepting the framing.

"Faster and cheaper" is the easiest claim in this industry to make and the least meaningful. Any chain is fast when nobody is using it. The number that matters is throughput under sustained real load, and most of the projects quoting theoretical figures have never been tested at one.

And a fix nobody uses is not a fix. Celestia solves a real architectural problem, is Halal, and scores 70, which is a fair score for genuinely novel infrastructure that has not yet proven adoption. That is not a criticism. It is the honest position for something early, and I would rather it read 70 than be flattered into the 90s.

What I actually hold to

Bitcoin's limitations are the direct consequence of the properties that make it what it is. Fixed supply, ruthless simplicity, no privileged parties, no yield to argue about. Every chain that removed one of those constraints got something real in exchange and gave something real up.

Some of those trades are excellent. Ethereum at 96 and Monero at 93 are not lesser things, and anyone telling you the entire altcoin market is a scam has not read the reports.

But I would be cautious about any framing where Bitcoin is the outdated version and the new chain is the upgrade. The reason Bitcoin holds the position it does is not that nobody has built anything faster. Plenty have. It is that nobody has built anything with fewer things to argue about, and in a field where the arguments include whether a yield is riba, having fewer of them is worth more than throughput.

We ranked the major chains against the framework in the Layer 1 comparison, and each asset above has its full report on the screener, with the evidence per line. If you are about to swap Bitcoin for something that fixes it, read the fix's report first. The cost is always in there somewhere.
