Sparkpool Ethereum Mining Pool Shares $300,000 USD Fee With Mistaken ETH User
ETH Mining Pool Sparkpool Splits $300,000 USD Fee With Accidental Sender
Something really curious happened at Sparkpool, an Ethereum mining pool, recently. According to the company, they received an email from a user who accidentally sent 2,100 ETH as a transaction fee to the company on February 19 (around $300,000 USD at the time).
At the time that the transaction was made, the money was actually frozen because the transaction was highlighted as suspicious and it was possibly sent by accident, which was what really happened.
In order to verify the information, Sparkpool checked the blockchain and determined that the person who sent the email was, indeed, the sender. After that, the company gave most of the money back to the person.
Obviously, the company would still have its fee after locating the sender, but you can bet that it was way less than 2,100 ETH. In fact, half of the money went back to the owners, a blockchain company based in South Korea.
In order to prove that they were really who they said they were, the company had to send 0.022517 ETH to Sparkpool, while later they agreed to share the profits in half, but only after another transaction, this one of 0.666 ETH, was made to Sparkpool.
The South Korean company thanked the miners and the pool and took its 1,050 ETH back, what heavily diminished its losses.
It looks like it is a very bad idea to make mistakes during blockchain transactions as the company might have lost the entirety of its money if the exchange did not agree in sending half back. In any case, the company already lost half of its money.
