The Ethereum network has recently been quite active, with on-chain activity reaching a record high. However, there is an interesting phenomenon behind this — security analysts have pointed out that some of the activity may be due to "address poisoning" type spam attacks.

The data is in front of us: since January, the number of new addresses and transaction volume on Ethereum have surged significantly. It looks prosperous, but there are hidden risks. The real turning point was the Dencun upgrade. After the upgrade, Ethereum's Gas fees dropped by over 60%, which sounds like a good thing, but also opened a door — low costs make large-scale spam attacks increasingly cost-effective.

Further research data shows that this type of poisoning attack has already accounted for a considerable proportion. In other words, not all network prosperity represents genuine ecological activity. On-chain activity is indeed increasing, but the quality varies. For those trying to assess the true health of the Ethereum ecosystem, this is a noteworthy signal.
