Coin Circle (120BTC.COM) News: Bitcoin fork project BSV (Bitcoin Satoshi's
Vision) has been reported to have been attacked by 51% since last week (17). A mysterious miner who controls about 51~80% of the computing power has produced a large number of empty blocks, causing many BSV transactions to be unable to be packaged into blocks, thus causing the entire chain to be damaged. Sometimes transactions are paralyzed.

According to the records of the blockchain browser, it can be seen that among the blocks produced in recent months and days, a very large proportion of blocks only contain one transaction, and this transaction only contains a transfer area. Block reward (6.25BSV) to address 1KPSTuJMCMRXrTWHfCwpiRZg1ALbJzh844.

 Miners maliciously crowd out other transactions

The address record shows that the miner has mined more than 31,174 BSV, and during the writing of this article, for example, starting from the height of block 762822, within two days up to the height range of 762523, there are 90 blocks in 300 blocks. The block is a malicious empty block, and the number of packaged transactions is only between 1 and 5, indicating that a large number of transactions have been maliciously excluded.

In terms of the total computing power of the entire network, the proportion of other named mining pools has almost disappeared after September, while the proportion of computing power belonging to the "unknown mining pool" label of Solo miners has increased significantly, accounting for more than 51% of the computing power of the entire network. It even exceeded 80% last week.

It is not yet clear whether they are all operated by the same miner, but according to block explorer transaction records, most of the computing power may be closely related to addresses starting with 1KPS.

 Official appeal to miners to come forward failed

After a large number of empty blocks crowded out other transactions, the BSV official Bitcoin association (Bitcoin Association) issued an announcement last week stating that miners used changing code strings to confuse the coinbase lexicon. It began to appear along with other suspicious behavior, mining empty blocks on the network, and steadily increasing the computing power to continue to interfere.

Therefore, the Bitcoin Association stated that it is taking action against the malicious behavior of this miner: The Bitcoin Association is taking action to contact all relevant exchanges and miners to freeze all block rewards related to this malicious miner, and will file criminal charges against the responsible entities. . The miner is encouraged to contact the Bitcoin Association at legal@bitcoinassociation.net within 24 hours to resolve this dispute.

The association also explained the behavior of malicious miners, saying that usually transaction packagers need to package transactions received by nodes into blocks, but this miner refused to package the transaction broadcasts received by nodes into blocks, which is essentially dishonest. This behavior will undermine the mission of the BSV blockchain and the interests of the community. It said that the Bitcoin Association contacted the miner multiple times and received no response.

The association also came up with the definition of honest nodes in the Satoshi Nakamoto white paper, and said that nodes that do not fulfill the tasks of the white paper will use Nakamoto consensus to deal with dishonest behavior, but the association did not specify how to deal with it: by voluntarily running in the network Nodes, nodes must follow the steps given in the Bitcoin whitepaper to be considered an honest node in the network. Nodes that do not fulfill this task will be considered dishonest nodes, and the white paper explains how honest nodes use Satoshi Consensus to deal with dishonest behavior... Honest miners have always proven that when miners take their role as professional business entities seriously , Bitcoin can scale to serve billions of users.

 BSV currency price has no impact

However, despite the official claim that mining empty blocks will harm the interests of the BSV community, after June this year, the BSV currency price did not differ much from the current level. Within a year, BSV reached a quotation of US$192.95 around November last year. Subsequently, as Bitcoin continued to decline, it reached US$46.44 on June 14. The quoted price before the deadline was US$46.98. The overall currency price has dropped by 75.65% after the bull market, but no empty blocks have affected its currency price.
