Yesterday, we wrote about the numerous speculations about what could cause the overload of Ethereum and rising transaction fees. The network was experiencing a great overload that seemed to have been caused by a single party, which is constantly smaller transactions, which in their nature seemed absolutely pointless.
I had the impression that someone is deliberately willing to pay for congestion, to expose in a favorable light any upcoming events. In any case, the spammer was willing to pay exorbitant transaction fees to the ETH network, and again throw suspicion on a rival network the EOS, raising the previously circulated rumors and suspicions.
The reason was in the game
One hypothesis, which stated for involvement in overload ETH lottery game, initially, was completely rejected because after all remember “cryptonomicon”, didn’t appear any more games with a similar number of participants.
As it turned out, the last version of overload was absolutely correct. This is somewhat reassuring, because it means that the overload was not caused by some malicious intent or hacking. But, on the other hand, a few guards that lottery game, working as a kind of Ponzi scheme, has caused such problems in the network.
A smart contract that caused the congestion, was created as a kind of clone of the game called FOMO3D on the Ethereum blockchain, which encourages the purchase of new keys to users, giving the chance to win the jackpot in Ethereum.
As reported the edition Cryptovest, at some point, the smart contract reached 34.5% of the consumption of essential gas.
Dan Larimer from block.one was right
Head of the division of Blockchain engineering and security Orbs, Leonid Thighs said:
“What we saw here, it’s like another clone of the famous game-a Ponzi scheme. Analyzing the machine code of this smart contract, it was discovered that he is a very similar game FoMo3D in which the winner was the one who bought the last “key” and won the jackpot, forcing the participants to send multiple transactions and in result spamming the Ethereum network”.
This continuous process of the game, and forced users to constantly send a small transaction led to this abnormal consumption of gas, severely clogging the network.
As you can see, in this situation it absolutely was right Dan Larimer of the block.one, who, denying the charges against another EOS said earlier, that does not make sense to spend money on attack Ethereum to slow down the network because an excellent job with this game, like CryptoKitties.
