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

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.
