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

“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.

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

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.
