Ethereum founder Vitalik Buterin shared his calculations as to how much it could do a spam attack on the network of ETH, which took place in June. According to him, we are talking about approximately $15 million.

“According to my calculations, the recent spam-attack on the Ethereum network was worth about $15 million (~5 million cups of green tea ~75 Lamborghini, ~25 rounds, seed rounds Coinbase or ~0.9% ICO Telegram). Free market principles do not allow me to be upset that someone is using bloccano ETH as he wants, but wow,” – wrote in his Twitter Buterin.

According to my estimates, the recent tx spam on the ETH network cost up to ~$15m USD (~= 5m green teas ~75 lambos, ~25 Coinbase seed rounds, ~0.9% of Telegram ICO)

Free market principles prevent me from being too upset at someone using the ETH blockchain as they wish, but wow.

If his calculations are correct, spamming cost a round sum, although it is unclear how coordinated this attack and what kind of coverage she actually had.

In his tweet Buterin avoids speculation on this subject. Instead, he shares his calculations, complemented by colorful equivalents, and expressed surprise at the amount which he succeeded in the end.

Recall that according to Buterin, decision scaling of the second – level sharding and Plasma will give Ethereum a capacity to handle 1 million transactions per second, and further – to 100 million transactions per second.
