F2Pool's handling of the abnormal Ethereum (ETH) transaction fee on June 11, 2020
On 2020-06-11 23:12, F2Pool mined an abnormal 3,221.6454 ETH transaction on the Ethereum network which also had a 2,310 ETH transaction fee. The TXID was 0xfd10c9a4507c4ebf1db9f71e05ba8ea09f3603c9012c24195d731a1fadfa14d9.

Later, on 2020-06-12 00:33, the sender contacted the F2Pool team and explained that they experienced a malicious attack on their wallet, and 5,531.6454 ETH (worth $1.23 million USD) was transferred out. The sender earnestly requested F2Pool to return the transaction fee part of the transaction to retrieve part of their losses.

F2Pool operates both a PPS pool (address mining) and a PPS+ pool (account mining) for Ethereum. This transaction was mined by the PPS pool (shown by the Hex code ending with "e9b1bc" in the block data).
Out of our humanitarian spirit, F2Pool has decided to return the transaction fee component of the transaction. It's not feasible to return the fee back to the original sender address as the address is also now controlled by the hacker. Therefore, we agreed to send the fee to a new address provided by the original address owner after full verification of the address and owner.
The following communication and verification process took several days of effort from us:
1. Verify the tag of the new address is consistent with the tag of the sender's original address and generates new blocks normally (another mining pool is the owner of the original address).
2. The original address holder was required to sign the new address 0x3ecef08d0e2dad803847e052249bb4f8bff2d5bb using the private key of the original address 0xda466bf1ce3c69dbef918817305cf989a6353423, and verify that the signature is valid and verified, as shown in the following message:
Address: 0xda466bf1ce3c69dbef918817305cf989a6353423
Message signature hash: 0x338dd6535591b136848abf5886e0ac36ba616e99f789c3e4693fcde2ba39c7ec24605c5fee7976780a526e0b97e92307a824bd6606839a575a2b358428b1f5061b
Original message: 0x3ecef08d0e2dad803847e052249bb4f8bff2d5bb

In order to say thank you to those that have firmly supported and trusted F2Pool even before all the details of the incident were fully disclosed, we negotiated with the original address holder to keep 10% of the transaction fee (231 ETH) and use it for a one-week event of 0% mining fees for F2Pool Ethereum mining, from 2020-06-20 to 2020-06-26 (inclusive). Any shortfall will be covered by F2Pool.

After we are completely satisfied with the verification process, F2Pool will return 2079 ETH to the new address 0x3ecef08d0e2dad803847e052249bb4f8bff2d5bb which has been provided by the sender.

We will embed this entire statement into the block when we return the ETH.

F2Pool will continue to follow its core values, providing reliable support for the healthy development of proof-of-work cryptocurrencies, and contributing its own strength to the overall growth of the blockchain industry. We hope to see the continued safe and smooth growth of the industry.

关于6月12日ETH异常交易的处理办法
北京时间6月12日07:12,ETH网络发生一笔手续费高达2310ETH的交易,转账金额为3221.6454ETH。该笔交易由F2Pool鱼池打包,交易ID为:0xfd10c9a4507c4ebf1db9f71e05ba8ea09f3603c9012c24195d731a1fadfa14d9。

随后,北京时间6月12日08:33,该交易发送方钱包地址持有人(以下简称原地址持有人)联系F2Pool鱼池,说明情况:该钱包遭到恶意攻击,节点钱包共被转走5531.6454 ETH(按当时币价,价值123万美元)。原地址持有人恳请F2Pool鱼池退回该笔交易的手续费,以挽回部分损失。

1. 验证原地址持有人提供的新地址的区块链浏览器标签,与原地址的标签一致,并持续正常出块(原地址持有人为矿池);
2. 要求原地址持有人使用原地址0xda466bf1ce3c69dbef918817305cf989a6353423的私钥对其提供的新地址0x3ecef08d0e2dad803847e052249bb4f8bff2d5bb进行签名,并验证,签名有效,验证通过,验证信息如下:

经过充分身份验证,F2Pool鱼池向原地址持有人提供的新的钱包地址0x3ecef08d0e2dad803847e052249bb4f8bff2d5bb退还手续费2079 ETH。
