Mining Pool Returns Half of Accidentally Sent Ether Fee Worth $300K

Ethereum mining pool Sparkpool has recently verified the identity of the user who had previously sent an exorbitant miner’s fee by mistake and has subsequently agreed to split the amount.

According to the mining pool, on February 25, it has received an anonymous email claiming they have accidentally attached a 2,100 Ether fee on February 19 worth approximately $300,000, prompting Sparkpool to freeze the unusually large mining reward.

To confirm the sender’s identity, Sparkpool responded that same day, asking the anonymous user to send 0.022517 in Ether through the same 0x587 address, which the user subsequently granted. Upon verifying the owner of the address which, according to Etherscan data, was a South Korea-based blockchain startup, an agreement between Sparkpool and the sender was reached, allowing the mining pool to keep half of the amount as mining reward while the other half was returned to the South Korean firm.

Upon Sparkpool’s request, a second transaction was also made on March 11 in which the user sent 0.666 Ether to the mining pool as confirmation of the agreement, with the user sending 0.666 Ether with a paragraph coded into the transaction’s hash. Sparkpool has since returned 1,050 ETH to the firm.

As stated in the paragraph:

“Thank you SparkPool and your miners for helping us to recover our loss, we are willing to share half of 2,100 ETH with the miners to thanks the miners’ integrity.”
