Cardano TPS Record Claim: One Address Made 25% Of Oct 7 Traffic

The Cardano TPS record that circulated on October 7 rests on a one-second reading, and the chain's own data shows what sat behind it. One address took part in about a quarter of all Cardano transactions that day. A BSCN post, citing Chainspect, said the network hit some 329 transactions per second and beat a 304 TPS mark from late 2024.

Where the Cardano TPS record number comes from

Koios block data for October 6 to 8 covers roughly 8,800 blocks. Blocks come every 20 seconds on average. The protocol cuts time into one-second slots, though, so two blocks can follow each other a second apart. Blocks in this sample topped out near 440 transactions. Divide one of those by a one-second gap and the result runs into the hundreds.

Block 14,038,759 shows it.

It carries 339 transactions, arrived one second after its predecessor and filled 96.59% of its size limit. Several other blocks that day held more than 300 transactions after one-second gaps. The sustained picture is far smaller. Over the whole two days the average was only 2.6 transactions a second. The best five minutes ran near 27.

One address behind the surge

Open that block up and most of it looks the same. Of its 339 transactions, 293 come from a single address starting addr1vyzte05z. Each one sends exactly 2 ADA with a fee of 0.164049 ADA and has the same size of 197 bytes. A total of 329 outputs of 2 ADA go to a single receiving address starting addr1vy740r73. The receiver ends up with about 21,700 ADA in over 10,800 tiny pieces.

Since October 6, Koios lists about 115,000 transactions involving the sender. Almost none were on October 6. On October 7 the figure was 81,831, which is 25% of the chain's 326,784 transactions that day. On October 8 up to 06:17 UTC it was 32,659, or 28.6%. In single hours the share climbed far higher, to 73% between 20:00 and 21:00 UTC on October 7 and 77% in the next hour.

What it costs and what it means

Fees on these transactions are cheap. At 0.164 ADA each, the 81,831 on October 7 cost about 13,400 ADA in fees, or roughly $3,400 at Binance's $0.2512 price. That is the price of lighting up a big share of network traffic for a day, assuming the sender paid them directly.

The chain data does not say why the address does this. It could be testing, an automated payment job or deliberate load. It is also not proof that Cardano cannot carry high throughput. Blocks were nearly full at times, which says capacity was used.

What it does show is the gap between a peak and normal use. A Cardano TPS record built this way measures block timing and bulk traffic from one sender, not organic demand. The 304 TPS mark from 2024 was not rebuilt here.
