From the '1 TPS' Joke to 'Unlimited Scaling': What Cardano Actually Changed

Sun, 30 Aug 2026 09:30:00 +0000

The last article covered where Cardano is going and why to believe it. This one zooms in on the hardest parts: what Dijkstra actually changes, and how it produces “unlimited scaling” and “two-minute settlement.” I’ll tie the whole piece to one question — where exactly is a consensus chain’s bottleneck?

The ceiling every chain hits: one formula

Nearly every public chain is bound by the same physical constraint: a new block must be seen by the network quickly. The reasoning chain is short: a block is the vehicle of consensus, and the whole network extends the same ledger. If a block is too big and takes too long to propagate, some nodes will produce the next block before seeing it, two branches grow at once, and the chain forks. So a protocol must choose between “big blocks” and “frequent blocks,” and throughput gets locked into “block size ÷ block time” — any chain that builds its security on global synchronization is stuck with this formula.

Cardano Roadmap in Review: From Chang Governance to Dijkstra's Three Steps

Sat, 29 Aug 2026 09:00:00 +0000

“Unlimited scaling,” “governance first,” “an academic chain” — around Cardano, the two phrases I’ve heard longest are the ones calling it a braggart and a vaporware artist. But this year, after checking the official roadmap and progress against each other one by one, I have to own an uncomfortable fact: the bragging is being delivered on, one item at a time. And along the way there was one genuine design change — and that single event says more about how Cardano ships than any slogan.

How a Cardano Hard Fork Works

Thu, 20 Aug 2026 10:00:00 +0000

The question that kept confusing me while studying Cardano was why every upgrade takes so long. The answer is simple: a Cardano upgrade isn’t decided by a team — it’s voted in by the whole network. The van Rossem hard fork (Protocol Version 11), which wrapped up in 2026, is a living example. This post breaks down its voting mechanism: how each of the three parties votes, what each one is responsible for, and how a hard fork runs its full course.

Slow Is Fast: Why Cardano's Governance Is So Careful

Mon, 10 Aug 2026 10:00:00 +0000

This post answers the question I kept asking myself while studying Cardano: why are its upgrades so slow? The answer isn’t technology — it’s governance. Every change to the core has to pass a long on-chain process. And that’s exactly the peak of Cardano’s “slow” philosophy.

First, decide what chain it wants to be

Cardano has never hidden its positioning: a settlement layer. It doesn’t want to be the “do-everything platform.” It wants to be the foundation that carries large, long-term, trustworthy transfers of value.

Ethereum Is Excellent — but Cardano's Approach Is More Advanced

Tue, 28 Jul 2026 10:00:00 +0000

When I study a chain, one question matters above all: can it get hacked? Let me say this up front: Ethereum is an excellent chain. It created the programmable general-purpose chain, and its flexible account model powered the entire DeFi explosion. This post uses a few real security incidents as comparison points to make one argument: for building smart contracts and crossing chains, Cardano’s approach is, in my view, more advanced.

Cardano's Biggest Upgrade Yet, Leios: 100x Throughput Without Weaker Security

Sun, 28 Jun 2026 10:00:00 +0000

The harshest thing said about Cardano, in my years of following it, is “1 TPS” — painfully slow. Its long-awaited answer is called Leios, which claims to push throughput up by tens to hundreds of times without lowering security by an inch. Its public testnet went live in June 2026, with mainnet targeted for the end of the year.

Let me explain Leios in plain language: what it actually changes, and why “faster without getting flimsier” holds up.

The Cardano SecondFi Signing Incident: How One On-Chain Transaction Leaked Ed25519 Private Keys

Sat, 27 Jun 2026 17:29:00 +0000

In late June, SecondFi — the Cardano wallet that grew out of Yoroi — made headlines across the ecosystem. No smart contract was drained. No private keys were stolen off a device. There wasn’t even a phishing campaign. The attackers simply read the blockchain. Within three days, roughly 16 million ADA (about $2.4 million at the time) vanished from 374 wallets, and the team urgently moved another ~129 million ADA to a third-party custodian as a rescue measure.

Cardano Smart Contracts Aren't Free — and That's Why They're Safer

Sun, 15 Mar 2026 10:00:00 +0000

The most common complaint I hear from developers is that writing contracts on Cardano feels “handcuffed.” Ethereum lets them tweak a balance in one line; on Cardano, the same thing takes a long detour, like dancing in chains.

I used to think that was a weakness. After actually understanding the ledger model, I’m convinced this “lack of freedom” is exactly why Cardano is safer than Ethereum. Let me explain in the plainest terms possible.

Why Is Cardano So Slow? Because Its Security Is Proved in Papers

Tue, 20 Jan 2026 10:00:00 +0000

My first impression of Cardano was a single word: slow. Other chains keep shouting about scaling and ecosystems; Cardano, after ten years, is still saying “our consensus paper got through another round of peer review.” I gave it the same nickname everyone does — the academic chain — and the same verdict: so slow, no good.

After actually digging into it, I’ve come to think that “slow” is the most valuable thing about it. Let me start from the bottom: how Cardano keeps its ledger, why it dares to write “security” into academic papers, and where it differs from Ethereum.
